practical guide

NAPREMO guide: safe advice before repairs, faults and renovations

Concrete advice that helps recognise symptoms, secure the place and prepare a useful report. No risky tricks and no hiding the cause.

The guide should help with decisions, not replace a specialist

In many faults the first minutes matter most: securing the place, taking clear photos, describing the symptom and avoiding larger damage.

First the symptom, then the cause, then the repair

A leak, a wet stain, a drain smell or a tripping breaker is only a symptom. The cause may be simple, but it can also involve installation, ventilation, a hidden leak or an installation error.

A good report shortens the way to repair

The best report says what is happening and since when, includes photos from different distances and tells whether the problem is growing.

forum-tested topics

Practical advice that really helps before a visit

These points help prepare the report and avoid actions that can make the problem worse.

plumbing

Leaking under the sink or washbasin

Most often the issue is the trap connection, misplaced gasket, deformed O-ring or dirt on the joint. A single drop does not yet show whether the cause is in the trap, drain, tap or valve.

What to check

  • Place a bowl, wipe the area dry and check where the first drop appears.
  • Take a close photo and a wider photo of the whole set under the sink.
  • Check whether water appears after opening the tap, draining more water or even without using the sink.

What not to do

  • Do not cover joints with silicone or glue.
  • Do not force plastic nuts if parts are misaligned.
Call/report the problem when: water flows constantly, a valve leaks, parts are cracked, access is built-in or the leak returns after tightening.
tap

Tap drips or the faucet is loose

With mixer taps, leaks often return because seals are worn. A loose faucet may mean a problem with the underside fixing, washer or gasket.

What to check

  • Check whether it drips from the spout, handle, rotating part or below the sink.
  • Photograph the faucet from above and from inside the cabinet.
  • Write whether the tap was moved or replaced recently.

What not to do

  • Do not disassemble the cartridge without shutting off water.
  • Do not ignore small drips near wood or cabinets.
Call/report the problem when: water gets under the worktop, the whole tap moves, a shut-off valve leaks or water cannot be closed securely.
drain

Bad smell from the drain

Common causes are a dry or sucked-out water seal, poor venting, dirt, hair or deposits in the overflow and drain.

What to check

  • Check if the smell appears after the drain has not been used.
  • Pour water into rarely used drains and observe.
  • Write if the drain gurgles or the smell increases after using appliances or WC.

What not to do

  • Do not rely only on strong chemicals if the problem returns.
  • Do not mask sewage smell with air freshener.
Call/report the problem when: the smell returns, water backs up, the drain gurgles or several points are affected.
damp

Mould, wet wall or fogged windows

Do not start with paint. First find the cause: weak ventilation, no air supply, thermal bridge, leak, roof, balcony, façade or insulation.

What to check

  • Take close and wider photos with the window, corner, floor or ceiling visible.
  • Observe whether it grows after rain, bathing, cooking, winter or closed windows.
  • Check whether vents are open and air can circulate.

What not to do

  • Do not paint over mould without removing the cause.
  • Do not seal ventilation grilles.
Call/report the problem when: the stain grows, the wall is wet near the floor, musty smell appears or mould returns after cleaning.
hidden leak

Wet stain on ceiling or wall

A wet stain may come from water, heating, roof, terrace, façade or condensation. Moisture measurement and observation help.

What to check

  • Mark the outline and take a photo with date.
  • Check whether it grows after rain, heating, bathing or using water.
  • Add photos of the room or floor above if possible.

What not to do

  • Do not break the wall blindly.
  • Do not dry aggressively if water is still arriving.
Call/report the problem when: the stain grows fast, water drips, electrics are nearby or the problem returns after rain.
electrics

Breaker or RCD trips

First disconnect devices and see whether the fault follows one appliance. Replacing protection with a stronger one is not a solution.

What to check

  • Unplug devices on the circuit and check if it still trips.
  • Note when it happens: kettle, oven, washing machine, light or no load.
  • Take a photo of the distribution board and the tripping device.

What not to do

  • Do not install a stronger breaker.
  • Do not bridge protections or open the board without qualifications.
  • Do not use a device that smells burnt or sparks.
Call/report the problem when: it trips without load, returns with one appliance, a socket heats up, lights flicker or there is a burning smell.
mounting

Something moves, falls off or will not hold

The issue is often the substrate, not just the plug: drywall, old brick, hollow block, concrete, plaster or crumbling wall.

What to check

  • Write what is to be fixed and its approximate weight.
  • Add a close photo and a wider photo of the place.
  • If known, state the wall type.

What not to do

  • Do not tighten a fixing that has already torn out the substrate.
  • Do not drill blindly where pipes or wires may be.
Call/report the problem when: the item is heavy, hangs above people, the wall crumbles or installations may be nearby.
silicone

Silicone by bathtub, shower tray or sink cracks

Silicone works only on a clean, degreased and dry joint. If the bath or tray moves, re-siliconing alone will not help.

What to check

  • Check if cracking is local or along the whole joint.
  • Take close and wider photos.
  • Write if leakage appears after bathing or showering.

What not to do

  • Do not put new silicone over old dirty silicone.
  • Do not cover a place where water has entered the casing.
Call/report the problem when: damp appears on the other side, the tray or bath moves, cracks return or there is a damp smell.
outside

Gutters, balcony, terrace and façade after rain

After rainfall the direction of water matters. A wet interior wall can have an outside cause: gutter, flashing, terrace slope, balcony, façade or drain.

What to check

  • Take photos during or just after rain if safe.
  • Show gutter, sill, balcony, terrace, plinth, ground by the wall or drain.
  • Write if the problem appears only after rain and from which side the wind blows.

What not to do

  • Do not assess the problem only from inside.
  • Do not climb onto a roof or high ladder without safe access.
Call/report the problem when: water enters inside, plaster falls off, gutter overflows, façade stays wet or work at height is needed.

for communities and managers

Order in reports means less chaos on site

In administrative reports, location, photos, urgency, responsibility for a common area or unit and later documentation matter. That is why NAPREMO Admin is the better path for managers, communities and cooperatives.

Go to NAPREMO™ admin

What to add to an administrative report?

  • address, staircase, floor, unit or exact common area location,
  • before photos and photos showing access,
  • whether the fault causes damage or risk,
  • whether a protocol, photos or staged work is needed,
  • contact person on site and access hours.

Have a problem and do not know how to name it?

In NAPREMO Fix you do not need technical terms. Choose the situation, add photos, enter a phone number and describe the symptom in your own words.

Report via NAPREMO™ fix

Frequently asked questions about repairs, faults, greenery and technical requests

Does NAPREMO handle small repairs such as a dripping tap or a loose door handle?

Yes. Small reports are a normal part of NAPREMO’s work. For a simple problem, choose NAPREMO Fix, add photos and describe the symptom without technical terms.

Can I report a problem if I do not know its technical name?

Yes. Describe what is happening, since when, exactly where and whether it is getting worse. A technical term is less important than clear photos and a specific description.

Which photos are best to add to a report?

Add a close-up, a photo of the whole location, a photo showing access and one photo of the surroundings. For water show the valves and drain; for electricity the consumer unit or socket; for moisture the entire wall, ceiling, window or floor.

What should I write to receive an accurate reply more quickly?

State where the problem is, when it began, whether it is constant or intermittent, what makes it worse and whether anything has already been repaired. Access, built-ins, floor, unit and available entry times are also useful.

When should I choose NAPREMO Fix?

Choose NAPREMO Fix for a single problem reported by a resident or property owner: something leaks, drips, comes loose, does not work, needs installing, checking or documenting with photos.

When should I choose NAPREMO Admin?

NAPREMO Admin is for property managers, communities and cooperatives when an organised report, location, photos, priority, documentation, work history or handling of multiple faults is required.

Does the advice in the guide replace a specialist’s visit?

No. The guide helps recognise symptoms, secure the place and prepare a useful report. Water, electricity, moisture, work at height or a risk of damage may require an on-site assessment.

Does NAPREMO provide quotations by phone?

A simple scope can be assessed preliminarily from a description and photos. Hidden leaks, electrical work, moisture, construction work or unusual access often require an inspection and a defined working method for an honest quotation.

Why can the same fault have a different price?

The price depends on access, material, substrate, urgency, parts, risk of further damage and diagnostic time. Replacing a visible seal is different from a leak behind a built-in unit or in a riser.

Is it worth sending photos before the specialist arrives?

Yes. Photos help select tools, parts and access method and assess urgency. Good photos often shorten the time on site and reduce unnecessary journeys.

What should I check first when water leaks under the sink?

Dry the area, place a bowl and check whether the first drop appears on the trap, valve, hose, drain or tap. Add a close photo and a wider photo.

Can I tighten a leaking trap myself?

Sometimes yes, if access is easy and the nut is only loose. Do not force plastic parts and do not twist elements that are misaligned.

Why does a trap leak after cleaning?

Usually because a seal is seated incorrectly, an O-ring has moved, the elements were joined at an angle or dirt remains at the joint. State whether the leak appeared after dismantling, cleaning or installing a new element.

Is silicone a good way to seal a trap?

No. Silicone usually hides the problem, makes later repair harder and does not replace a correctly placed gasket.

Water drains slowly. Is the trap always blocked?

No. It may be the trap, a blocked pipe, poor slope, venting issue or a further part of the installation. Gurgling and several slow drains are important signals.

Bad smell from a drain — where to start?

Check whether the drain was unused and whether water remains in the trap. If the smell returns or the drain gurgles, the cause may be venting or sewage installation.

Do soda, vinegar or pipe chemicals solve drain smell?

They may remove deposits, but they will not fix a sucked-out trap, lack of water seal, bad venting or a leaking connection.

A tap is dripping. Is it urgent?

A small drip is not always an emergency, but it should not be ignored near wooden tops, cabinets or when the shut-off valve also leaks.

The faucet is loose. Can it just be tightened?

Sometimes, but first check the underside fixing, washer and gasket. A loose faucet can let water under the sink or worktop.

Can a loose tap cause a leak under the sink?

Yes. Water can get under the worktop or into the cabinet even when the tap itself still works. Check not only the spout but also the mounting and the contact with the worktop or sink.

There is a wet stain on the ceiling. What first?

Mark its outline, take a photo with date and check whether it grows after rain, heating, bathing or using a specific water point.

Can I dry and paint a wet stain immediately?

No. First find the cause. Painting or drying while water is still arriving only hides the symptom and the problem returns.

How to tell leak from ventilation moisture?

A leak often follows rain or water use and may have a clear path. Ventilation moisture often appears in corners, by windows and in cold periods.

Is fungicide enough for mould?

No, if the cause remains. First check ventilation, air supply, thermal bridges, leaks and the way the room is used.

Why can mould appear after window replacement?

New tight windows reduce natural air exchange. Without air inlets and working ventilation, humidity condenses on cold surfaces.

Should a ventilation grille be covered because it is cold?

No. Blocking ventilation can increase humidity, mould and safety risk. The cause of cold draft should be checked, not covered blindly.

What can wet walls near the floor indicate?

Possible causes include a leak, ground moisture, failed insulation, a thermal bridge, residual moisture after flooding or water from outside. Photos of the skirting area, floor and outside wall and information about changes after rain are important.

Does a moisture meter always give a clear answer?

No. The result depends on material, depth, salts and method. Measurement is a clue, not always a final diagnosis.

A breaker trips. What can I safely check?

Unplug devices on that circuit and note when it trips. Do not open the distribution board or replace protection with a stronger one.

RCD trips without load. What does it mean?

It may indicate insulation damage, moisture, faulty device or installation issue. This needs proper diagnosis.

Can I install a stronger breaker so it does not trip?

No. A stronger breaker can remove protection and create fire or shock risk. The cause must be found.

Socket heats up or smells burnt. What to do?

Stop using it, switch off the circuit if safe and report it. Heat, sparks or burning smell are warning signs.

Lights flicker. Is it only bulbs?

Sometimes, but it can also be loose connection, overloaded circuit or installation problem. Note when flickering appears.

Does NAPREMO carry out small electrical jobs?

Yes, but the scope must be safe and comply with technical requirements. Installations, consumer units, protection devices and measurements require proper assessment and a person with the appropriate qualifications.

What to do when something falls off the wall?

Do not tighten the torn fixing. Show the substrate, the hole and the element weight so the fixing method can be changed.

Can a heavy shelf be mounted on drywall?

Yes, but only with a method matched to load, board structure and studs. Random plugs are not enough.

How can I check whether tiles are bonded to the substrate?

As an initial check, tiles can be tapped gently and listened to for a hollow sound. This does not replace an assessment, but it may indicate that tiles have detached and are being held mainly by the grout.

Tiles are falling off in the bathroom. Is reattaching one enough?

Sometimes, but if neighbouring tiles sound hollow, the substrate is damp or a larger area is detaching, the cause must be checked. Reattaching one tile may not solve a wider problem.

Cracked silicone in the bathroom — just add new?

No. Old silicone must be removed and the place cleaned and dried. If the tray or bath moves, the cause must be fixed first.

Why does bathroom silicone turn black?

Usually because of humidity, poor ventilation, dirt or water remaining on the joint. Cleaning alone will not help if the place stays wet.

Does NAPREMO carry out unusual installations?

Yes, when the fixing method, access and responsibility can be defined safely. For unusual installations, photos, dimensions, the element’s weight and information about the substrate are essential.

Gutter overflows in rain. What photos help?

Show the gutter, downpipe, roof edge, wall below and the place where water overflows. Photos during or just after rain are useful if safe.

After rain the inside wall gets wet. Can the cause be outside?

Yes. It may be the gutter, flashing, balcony, terrace, façade, plinth or drainage outside.

Should I climb onto a roof or high ladder to take photos?

No, not without safe access and protection. A wider photo from the ground is better than taking risk.

How to report a fault in a common part of a building?

Give the address, staircase, floor or exact place, add photos and write whether it causes damage or risk.

What should a report for a manager include?

Location, photos, urgency, access, contact person and information whether documentation or staged work is needed.

Why are before-and-after photos important for communities and cooperatives?

They make the scope clear, help settle the work and create evidence of what was repaired.

Should urgency be defined in an administrative report?

Yes. It helps decide whether the place only needs planning or immediate securing.

When can a small fault become a large problem?

When water, electricity, loose elements, mould, repeated leaks or damage to common areas are involved.

Does NAPREMO work only on large jobs?

No. We accept single small faults and larger technical scopes.

Can several faults be reported at once?

Yes. List them separately and add photos for each place. For many administrative reports, NAPREMO Admin is the best path.

Do you help choose the repair method?

Yes. The method depends on cause, access, substrate, safety, materials and expected durability.

Do I need to buy parts before the visit?

Usually no. Send photos first. Buying parts blindly can lead to wrong dimensions or poor compatibility.

How to prepare the place before a specialist arrives?

Clear access, remove items that block work and secure children, pets and valuable items if possible.

Does lack of access to a built-in installation change the scope?

Yes. Built-in pipes, valves and drains often require opening access or choosing a diagnostic method first.

Should I describe earlier repairs?

Yes. This helps understand whether the problem is new, repeated or caused by earlier work.

Does NAPREMO operate locally in Łódź and nearby areas?

Yes. The website focuses on Łódź and nearby towns in the service area.

When should I choose NAPREMO™ Green?

Choose NAPREMO™ Green when the request concerns a tree, shrubs, a hedge, lawn, planting, irrigation or clearing a green area. The form is designed to collect the information needed to assess the site, scale and access from the start.

What work can be requested through NAPREMO™ Green?

You can request tree care and pruning, work on shrubs and hedges, mowing, lawn renovation, planting, irrigation work and clearing overgrowth or neglected land. If the issue does not fit a category exactly, choose the closest one and describe the scope in your own words.

Can I request mowing of tall grass and clearing neglected land?

Yes. For tall grass, self-seeded growth, scrub and neglected land, provide an approximate area, vegetation height, site access and several photos from different angles. This helps assess the equipment required and how the green waste should be handled.

Do you trim hedges and shrubs?

Yes. In the request, provide the approximate length and height of the hedge or the number of shrubs, and state whether you need routine shaping, heavier reduction or clearing overgrown vegetation. Photos showing the whole hedge line are more useful than close-ups alone.

Does NAPREMO™ Green work on large trees?

We accept such requests for assessment. With a large tree, its height, position relative to buildings, fences, cables and other obstacles, equipment access and the condition of the tree are important. These details help determine a safe method and the access required.

What photos should I add for a tree request?

Add a photo of the whole tree from the base to the crown, photos of the trunk, crown and surrounding area, and any nearby obstacles. If the issue concerns a specific branch, also show it from a wider perspective so its position relative to the surroundings is clear.

Can greenery work be priced from photos?

For a simple and clearly shown scope, it is often possible to give an initial estimate or price range. Large trees, difficult access, extensive neglected areas or work requiring specialist equipment may need an additional site assessment.

How should I describe the size of a lawn, hedge or area if I do not know the exact measurements?

You do not need a professional survey. Give an approximate size, such as the hedge length, estimated lawn dimensions, number of trees or shrubs, or compare the area with a familiar object. Wider-angle photos also help confirm the scale.

Can lawn, hedge, shrub and tree work be combined in one request?

Yes. If the work concerns one site, it is best to submit it in one request and describe each scope in order. This makes it easier to assess the whole job, select equipment and plan the sequence without splitting one project into several unrelated visits.

What happens to branches, grass and other green waste after the work?

The handling of green waste is agreed before the job. Depending on the scope, it can be gathered in one place, prepared for collection or included in the removal service. State in the request what you expect after the work is completed.

Does NAPREMO™ Green serve property communities, businesses and larger sites?

Yes. A request can concern a private garden, grounds around a building, common areas, company premises or a larger site. For larger areas, photos, approximate size, equipment access and a contact person responsible for access are especially important.

Can I request planting or irrigation work?

Yes. For planting, provide the location, number or type of planned plants and the expected result. For irrigation, state whether the request concerns an existing system, a repair, an extension or a new installation. Site photos make assessment easier.

Can I arrange regular maintenance of a green area?

Yes. If the site needs recurring mowing, hedge cutting, shrub care or other regular work, describe the frequency and scope. This allows us to determine whether a one-off job or a regular maintenance schedule is more suitable.
