The scary words
Words such as subsidence, asbestos, indemnity and flood risk can be unsettling when they appear without much context. The name of an issue is only the beginning; what was found, how far it extends and what it means for this property matter far more.
Damp and condensation
A high moisture reading or visible staining does not identify the source. Possibilities include condensation, leaking plumbing, failed rainwater goods, defective pointing, raised external ground, poor ventilation or water moving through part of the building.
Ask where the moisture was found, whether there is active damage, what construction the home uses and what evidence supports the proposed cause. If specialist advice is needed, consider whether the inspector is independent of the treatment being sold.
Cracks, movement and subsidence
Buildings move for several reasons and many cracks are not progressive structural failure. Width, pattern, location, change over time and the surrounding ground all matter. A general surveyor may recommend a structural engineer when the cause or significance cannot be settled visually.
For known historic subsidence, obtain the reports, repair and monitoring history, guarantees and insurance claims. Check current buildings-insurance availability and terms before exchange; a repaired structure and an awkward insurance history are separate questions.
Asbestos
Some older products may contain asbestos, but appearance alone does not confirm it. Sampling and analysis are needed for certainty. Material in good condition and unlikely to be disturbed can often be managed in place; planned drilling, removal or refurbishment changes the risk.
Do not take an improvised sample. If your plans could disturb suspect material, get competent advice on the appropriate survey, sampling and removal route.
Indemnity insurance
A legal indemnity policy covers a defined financial loss if a specified title or consent risk is enforced. It does not provide missing planning or building-regulations approval, make construction sound or repair a defect.
Read the insured risk, exclusions, duration and who benefits. Contacting the person or authority able to enforce the issue can prevent cover being available, so ask the conveyancer before trying to investigate it yourself.
Japanese knotweed and other invasive plants
Identification, location, extent, lender policy and a credible treatment plan matter. A plant name alone does not tell you whether lending or use of the garden is affected. Use a competent specialist and check whether any management plan and guarantee will transfer.
Flood risk
Official long-term maps are useful screening, while property searches, local history and insurance quotations add different information. Surface water, river, sea and groundwater risks are not interchangeable. Find out whether the home itself has flooded, not only whether an area is shaded on a map.
Spray foam insulation
Roof spray foam can obstruct inspection and create lender or insurance concerns, depending on the product, installation, roof condition and available documentation. Removal alone may not answer every concern, so find out what was installed, who did the work, which records survive and what evidence the lender and surveyor require.
Flying freehold, covenants and private services
These are legal arrangements rather than physical defects. A flying freehold means part of one property lies above or below another ownership. A restrictive covenant limits use. A private road, drain or shared drive needs rights and repair arrangements.
Tell the conveyancer what you intend to do and ask who has the right to use, enter, maintain and recover costs. The practical relationship and the written title both matter.
What has actually been observed? What is the likely cause? What remains unknown? Which decision could the answer change?
If the person raising the issue cannot answer all four, ask what further inspection, document or specialist opinion would provide the missing evidence.
What to check for your purchase
- Ask whether the report describes a visible sign, a suspected cause or a confirmed diagnosis.
- Find out whether the issue affects safety, ongoing damage, the mortgage, insurance or a later sale.
- Ask the surveyor which independent specialist is needed and what question that person should answer.
- Read what an indemnity policy actually covers.
- Tell the conveyancer if you plan to alter, extend, let or run a business from the property.
- Estimate the likely repair and financial consequences before deciding whether to continue, renegotiate or withdraw.
