Frequently asked questions

Most residential surveys take between one and two hours on site, with the written report issued within two working days.

If your homebuyer report flagged elevated moisture readings, yes. A specialist survey tells you whether the issue is cosmetic, a maintenance item or a significant cost, which is useful in price negotiation.

Lenders generally accept a written specialist report that identifies the cause, the works required and the cost. We format reports with this in mind.

Typically 600mm to 1200mm. Damp appearing higher than that is almost always penetrating damp, condensation or a leak.

No. Waterproof paints and sealers trap moisture and salts, which usually pushes the problem higher up the wall or into the adjoining room.

Renovating plaster generally needs four to six weeks to dry before decorating, and we recommend a breathable emulsion for the first coat.

Winter brings prolonged driving rain and lower evaporation rates, so masonry stays saturated long enough for moisture to reach the inner face.

Only when it is a breathable, vapour-permeable product and the underlying defect has been repaired. Non-breathable coatings trap moisture and cause worse problems.

Yes. We use towers, ladders and access equipment appropriate to the elevation and can arrange scaffolding for larger repairs.

It helps, but it relies on occupants and wastes heat. Controlled background ventilation gives a consistent result without the heat loss.

A positive input ventilation unit sits in the loft and gently supplies filtered air into the home, diluting humid air and pushing it out through natural leakage paths.

Insulation raises surface temperatures and helps considerably, but without ventilation the moisture still has nowhere to go.

It can aggravate respiratory conditions and allergies, particularly for children, older people and anyone immunosuppressed. It should be removed promptly and properly.

Household bleach can decolourise surface mould but does not penetrate porous plaster, so growth usually returns. Professional biocides and moisture control are required.

In most cases yes. For extensive remediation we will advise on which rooms to avoid during works.

Most homes are completed in one to three days depending on the number of rooms and whether ventilation works are included.

They slow regrowth but are not a cure on their own. Used after biocidal cleaning and alongside ventilation they are very effective.

Yes, once dry. We advise keeping treated rooms clear for a few hours and ventilating during application.

A typical single-room escape of water takes one to three weeks depending on the materials affected and how long the leak ran.

For anything beyond minor staining, usually yes. We can quote for the works and supply the evidence your insurer will ask for.

Rarely advisable. Natural drying is slow and often stalls, allowing mould and rot to establish in enclosed voids.

Not necessarily — we can carry out detection and, for many leaks, the repair itself. If specialist works are needed we will tell you.

Only if the material is still wet or the leak persists. We test before decorating and use a stain-block primer.

We generally offer appointments within a few days across Banstead and neighbouring areas, with faster slots for time-critical transactions.

In most cases we locate the leak to within a small, clearly defined area, which keeps opening-up works to a minimum.

Many policies include a trace-and-access limit specifically for this purpose. Check your schedule — our report supports the claim.

Yes. Screeded and concrete floors are routine work for us using thermal, acoustic and tracer gas methods.

If it is safe to do so, releasing trapped water into a bucket reduces the collapse risk. Turn off the circuit first and call us.

Often yes. If the board is sound and dry, a stain-block and redecoration is enough.

Yes, we repair traditional ceilings using compatible materials rather than automatically replacing them with plasterboard.

It depends on the material. We always compare against a dry control area in the same property rather than relying on a single number.

Yes. Screed hygrometer testing to the relevant standard prevents costly flooring failures.

Yes, we produce clear, evidence-based reports suitable for landlords, tenants, agents and insurers.

Fees depend on property size and scope. Call us with the address and we will quote before attending.

Yes, a costed schedule is included, but you are under no obligation to use us for the repairs.

No. It needs timber moisture content above roughly 20% to establish; the name refers to the dry, crumbly state of the decayed wood.

In warm, unventilated conditions it can advance rapidly, which is why early professional assessment matters.

Not always. Outbreaks caught early are often contained to a small area — the extent depends on how long the moisture has been present.

Wet rot stays in wet timber and lacks the white mycelium strands and rust-red spore dust typical of dry rot. We confirm on site.

Frequently yes, with spliced timber or resin repair systems, which is far cheaper than replacing an entire frame.

We apply preservative to adjacent sound timber as a precaution once the moisture source is removed.

Fresh, clean-edged holes with light-coloured bore dust suggest activity. Dark, dusty holes in dry timber are usually historic.

Usually only for a few hours during and after treatment. We will advise for your specific job.

Yes, our timber treatments come with a written guarantee subject to the moisture source having been resolved.

Membrane systems are more forgiving and easier to maintain in older properties; tanking suits sound, structurally stable substrates. We advise per property.

Only if water cannot discharge to a suitable drain by gravity. Where a pump is required we always recommend a backup.

With a properly designed waterproofing system, ventilation and the necessary building regulations approvals, yes.

Warm humid summer air entering a cold cellar condenses on the cool surfaces, which is why summer can be worse than winter.

No — sealing usually makes it worse. Controlled ventilation is almost always the better answer.

Yes. Moist air migrates upward and can raise humidity and cause mould at ground floor level.

A minimum 15-minute overrun, or better, a continuous-run unit that boosts on humidity and never fully switches off.

For long duct runs or noisy locations, yes — a loft-mounted inline fan offers much better performance and is quieter in the room.

It helps but the moisture has usually already spread by the time the window is opened, and in winter most people close it too soon.

A trickle vent or slightly open window helps considerably. Continuous low-level ventilation is better than occasional wide opening.

Usually because it is the coldest — often north-facing, above a garage or with two external walls.

It manages the symptom effectively and can be a good interim measure, but ventilation and heating tackle the cause.

Sustained wetting can decay roof timbers and ruins the performance of insulation, so it should be resolved rather than ignored.

Ventilation helps, but if a bathroom fan is discharging into the loft no amount of vents will keep up. Both sides need addressing.

No — insulation pushed into the eaves blocks the airflow path. Ventilation trays maintain the gap.

In almost all cases yes. Your policy may nominate a supplier, but you are generally entitled to obtain and submit your own quotation.

Policies differ. Sudden escape of water is normally covered; long-term gradual seepage often is not. Our report clarifies which applies.

Yes, with your authority we correspond with adjusters and claims handlers to agree the scope.

Turn off the internal stop tap, switch off electrics to the affected area at the consumer unit, and move belongings clear.

We quote clearly before attending so you know the cost of the emergency visit up front.

Yes. We frequently work between leaseholders, freeholders and managing agents to resolve these situations.

Running costs vary with the equipment used and duration. We tell you the expected consumption up front and, on insurance jobs, this is usually recoverable.

Usually yes, though the equipment is noisy and rooms will feel warm. We plan around occupied homes routinely.

Warm dry air is fed directly into a sealed void — under a floor or inside a wall cavity — where a room dehumidifier cannot reach.

Allow four to six weeks for renovating plaster and longer for lime, then use a breathable mist coat first.

Yes, we can repair and match cornices and decorative plasterwork in period properties.

Not usually. We remove to a sensible margin beyond the damage and blend the repair into the existing surface.

In most cases yes. We source matching or closest-available materials and will show you samples before ordering.

Yes, decoration is included in our reinstatement scope so the room is finished when we hand it back.

A single room is typically three to seven working days depending on the finishes involved.
