Make sure the cause is understood
If an overflowing drain, defective rainwater pipe or low threshold contributed to the flood, ask what has been done about it. Repairs to decorations are not a prevention scheme. If the cause is regional flooding, understand what protection measures are realistic.
Look for evidence of drying
Ask who measured the moisture condition, what areas were tested and how hidden voids were checked. Different materials behave differently, so a single reading at the surface may not be enough. Keep records of drying equipment and completion assessments.
Services need their own sign-off
Electrical work should be inspected and certified where required by a suitably qualified electrician. Gas installations and appliances affected by flooding need a Gas Safe registered engineer. Check plumbing for leaks and consider whether drains require inspection after debris or movement.
Inspect floors, plaster and joinery
Check for loose finishes, swelling, new staining, odours and changes to doors or floors. Any remaining damp or distortion should be investigated before painting and fitting new floor coverings. Photograph concerns and raise them promptly with the contractor.
Keep documents and warranties
Retain the agreed work specification, changes, invoices, test results and product instructions. If the claim was insured, keep correspondence and the final settlement papers. Good records are useful if moisture problems return or you later sell the house.
Plan for the next storm
Think through flood warnings, access to barrier equipment, valuable possessions and who could help if you were away. Some flood resistance systems need regular tests. Aim to make the next response quicker and safer, not merely to return the house to the way it looked before.
Agree exactly what has been repaired
Compare the finished work with the insurer-approved schedule, survey findings and contractor quotation. Has the original route of water entry been addressed, or have wet finishes merely been replaced? If the proposed drainage, barrier or threshold changes were altered during the project, ask for a written explanation. Keep photographs of concealed work before it was covered over. A neat paint finish does not establish that the specification was followed.
Ask for evidence, not just reassurance
Where a drying company was involved, request its completion record and an explanation of the measurements used. For newly laid floors, ask how moisture conditions were checked against the flooring manufacturer’s requirements. Record any remaining staining, swelling, odours or soft spots before signing final paperwork. If a dispute develops later, dated records are far more useful than remembering that a contractor said everything was dry.
Check utilities and equipment
Electrical systems affected by floodwater should have been inspected and made safe by a competent electrician. Gas appliances and boilers exposed to flooding also require an appropriate professional check. Confirm that any pumps, alarms, non-return valves or barriers fitted as part of the repairs have been demonstrated, tested and supplied with instructions. Know who should be contacted if an alarm sounds or the equipment fails during heavy rainfall.
Inspect the details people tend to miss
Look behind removable kitchen plinths and around the bases of cupboards where access is safe. Check skirting joints, door frames, under-stair cupboards, floor edges and ventilation openings. Ask who has dealt with debris and possible contamination in voids rather than assuming the visible room is the whole job. If an area has been left inaccessible, request a clear record of why it was considered sound.
Warranties and future maintenance
Keep invoices, product data, relevant test results, guarantees and photographs together. Note which items require routine cleaning, such as gullies, pump sumps and channel drain gratings. A flood barrier may require seals to be examined and fitted in a particular way before each event. Maintenance instructions matter just as much as a warranty certificate if the house is at continuing risk.
When to raise concerns
Tell the contractor and insurer promptly about unresolved problems, preferably in writing with dated photographs. Explain the symptom precisely: water entering during rain, plaster staying damp, a drain still overflowing or a floor continuing to move. Avoid commissioning another full set of repairs before establishing responsibility for the defect, unless work is urgently required to protect safety or prevent further damage.
