Slim Cavity Units across Surrey
Nothing about Slim Cavity Units in Surrey is settled until someone has been on site. The building stock is interwar detached stock, Arts and Crafts houses and 1930s semis, so we expect variation before we ever pick up a tape. Then there is mild but damp, with heavy tree cover holding moisture against elevations, which reliably produces sap staining and green growth on north elevations followed by joint opening given enough seasons. What you are paying for is narrow cavities that perform while keeping the sightline historic.
Nothing is ordered until someone has stood in front of the opening with a tape. Send us sizes and a photograph and we will come back with a fixed written price.
One local point to factor in: high-value stock where owners specify hardwood over softwood as standard.

Frequently asked questions
Do you cover Surrey?
Yes. We cover the whole of Surrey including Guildford, Woking, Epsom, Redhill and the surrounding villages. High-value stock where owners specify hardwood over softwood as standard. Because mild but damp, with heavy tree cover holding moisture against elevations, we allow for it at survey stage rather than discovering it on the day.
Is the timber certified?
All our stock is FSC certified and chain-of-custody documentation is supplied with the order, which most main contractors and specifiers now require for their records.
Can you price from drawings?
Yes. Send a drawing set or a schedule and we will price against it. If anything is ambiguous we will query it before quoting rather than assume and reprice later.
Do you take a deposit?
Not before the measured survey. A deposit is only requested once the survey is complete and you have approved the final schedule and price.
Do you work in hardwood or softwood?
Both. Engineered hardwood is the default where movement or exposure is a concern, and slow-grown softwood is often the better value choice for painted work in sheltered positions. We will tell you which we would specify and why.
