Verify the record
The operative matches reported evidence with its position in the property.
Estate flats, newer developments and busy short-stay accommodation need careful scoping. We inspect the affected room and resolve block access before deciding whether controlled heat is suitable.
Tell us the block, floor, room use and latest confirmed sign.

Investigate before treating
A surveyor examines the places most closely linked with sleeping: mattress seams, divan fabric, frame joints, headboard mounts and bedside storage. Sofas and armchairs are checked when occupants spend long periods there.
We ask when signs first appeared and whether luggage, laundry or second-hand furniture recently entered the home. Those details guide the search, but only credible evidence determines the working area.
Room dimensions, fitted cupboards, electrical circuits and sensitive contents are then recorded. This establishes whether safe, measurable heating is realistic.
On the day
The operative matches reported evidence with its position in the property.
Included rooms and excluded areas are confirmed with the responsible person.
Protected items and essential removals are checked against the written list.
Machines and monitoring probes are arranged to suit volume and furniture.
The team compares readings and redirects circulation where progress differs.
Cooling, safety checks and handover are recorded before occupants return.
Matching method to evidence
Suitable rooms can be warmed under observation, with emphasis on protected harbourages rather than open air alone.
A residual plan can address selected cracks and materials where heating would be impractical.
Inspection, monitoring and different controls may be combined when the findings justify distinct stages.
Clues for the surveyor
Use a sealed pot or clear photograph and label the finding location.
Small dark marks gain meaning when their position on furniture is visible.
Photograph them before washing, while remembering that stains have other causes.
Pale skins or eggs may sit behind fittings and along sheltered edges.
A simple chronology helps distinguish an isolated introduction from repeated activity.
Skin marks are too variable to support treatment without corroborating evidence.
Homes around Custom House
Stair cores, secure doors and parking controls shape the arrival arrangements.
Management may require contractor registration and a reserved service lift.
Compact bedrooms and narrow stairs affect working space and equipment movement.
Laundry habits and use of communal furniture can connect otherwise separate rooms.
The inspection considers where each person sleeps and where bags are stored.
Agent and occupier should agree access, preparation and responsibility for handover.
Guest histories inform enquiries, while room evidence controls the final scope.
Getting the property ready
Keep bed components together so their joins remain available for inspection.
Avoid taking clothing or bags to friends, neighbours or untreated rooms.
Point out prescriptions, pressurised cans, wax, plants and fragile possessions.
Make alternative arrangements for every person and pet during restricted access.
Create safe working space beside key furniture without scattering stored contents.
Confirm which sockets and circuits are available and report known defects.
Supply working keys, fobs and permissions for the agreed rooms.
Tell reception or estate staff when the technicians and equipment are expected.
Building the quote
Size, furnishings and circuit availability establish the initial requirement.
Every added room has an evidence-based reason and its own preparation needs.
Working hours, permits and site procedures can affect time on the premises.
The final price reflects the agreed work, not a generic flat type. See Prices or contact the team.
Custom House & East London
Road conditions around ExCeL can change during large events, while newer blocks may restrict contractor parking. Confirming a lawful unloading location avoids an unsafe or excessively long carry.
The site brief should include the correct entrance, intercom, floor, stairs and lift capacity. If management requires documents in advance, send them before the appointment day.
Practical questions
No. Reactions have many causes and differ between people. Identification needs physical evidence or examination of likely harbourages.
Tell whoever controls keys, parking, communal entry or contractor approval. They may hold useful access information.
Wait for instructions. Unplanned sorting can disturb evidence and carry insects beyond the affected bedroom.
That depends on their specifications. List computers, batteries and sensitive equipment so the technician can advise correctly.
Open air warms differently from furniture and perimeter spaces. Comparing locations shows where circulation needs adjustment.
Duration depends on setup, monitored progress and cooling. The booking allows for every stage.
Not until hand-back. Equipment shutdown is followed by cooling and safety checks before anyone returns.
Usually not. Evidence, property connections and movement history identify any justified additional access.
Secure it, note where and when it appeared, and contact the team before moving possessions or using another treatment.
Arrange an assessment
Provide the Custom House address, affected room, floor, evidence and site contact. We will match the appointment to the property and explain preparation clearly.
