Structural Survey in Addlestone

A structural survey is sensible when you see cracking, movement, sloping floors, sticking doors or signs that an extension has not tied into the original building correctly. It is also the right choice after a lender or buyer raises concern about subsidence, a chimney leaning, or work carried out without structural calculations. In Addlestone, that often comes up in converted buildings around Station Road, newer schemes at Woburn Hill, and older homes that have had walls removed or openings widened. If the issue affects the structure, our survey is the tool that gets to the cause.

A building survey, usually a RICS Level 3 survey, gives a broad condition review across the property. A structural survey goes deeper into load paths, foundations, structural movement and the reason a defect is happening. Our chartered structural engineers can also produce calculations and repair specifications where the problem needs design input, which is not the same as a general condition summary. If the concern is a crack, a bulge or a failed alteration, the structural route is usually the better fit.

Our structural survey prices start from £500, with the final fee depending on the size of the property, the severity of the problem and how easy it is to access the parts we need to inspect. A simple crack investigation in a small house will usually cost less than a complex appraisal of a conversion with limited roof or subfloor access. If calculations or a more detailed defect report are needed, the fee may rise to reflect the extra engineering work. The quote is set around the actual inspection, not a one-size price.

A typical site visit takes 2-3 hours, although a larger property or a severe defect can take longer. Our engineer needs time to inspect the issue, measure movement, assess the construction and review any drawings or paperwork that are available. The written report is usually delivered within 5-10 working days after the inspection. If the property is one of the larger schemes or a complex alteration around Addlestone, we may spend longer on the analysis stage.

Yes. Our structural engineers assess subsidence by looking at crack form, level differences, drainage, trees, soil behaviour and the age of the movement. We also separate subsidence from other causes such as thermal movement, drying shrinkage or poor alterations, because the repair route changes completely once the cause is known. If the evidence points to active movement, we may recommend monitoring over time before any remedial work starts. That avoids unnecessary underpinning or rushed repair decisions.

Insurance can cover structural repairs if the damage is linked to an insured event, but each policy has its own terms and exclusions. Subsidence claims often need monitoring, photographs and level readings before an insurer will agree the next step. Our report gives clear evidence for that process, including the likely cause of movement and whether the problem is historic, ongoing or stabilising. If you are making a claim, a precise engineering report is usually far more useful than a short note.

Yes, and those jobs are common in Addlestone because the local stock includes conversions like Aviator Park and newer schemes such as Clifton Gardens on Woburn Hill. Extensions can fail where the new and old structures meet, especially if openings were widened, floors were altered or foundations were not matched correctly. Our engineers check the junctions, the load transfer and any sign of movement at the interface. That is often where the first real clue appears.
