Slim Cavity Units across Suffolk
If you are looking at Slim Cavity Units in Suffolk, the timber is only half the decision. Most of what we survey locally is colour-washed timber-framed cottages, wool-town merchant houses and coastal stock, which is not built to any modern module. What accelerates it is dry easterly climate with strong coastal salt exposure, and lime-render and timber junction failure where movement opens the seal follows sooner than owners expect. What we concentrate on is narrow cavities that perform while keeping the sightline historic.
We would rather spend an hour surveying than a week correcting. Give us the basics and you will have a written figure, not a range that moves later.
One local point to factor in: Lavenham-style timber framing needs specialist scribed repair, not replacement.

Frequently asked questions
Do you cover Suffolk?
Yes. We cover the whole of Suffolk including Ipswich, Lowestoft, Bury St Edmunds, Felixstowe and the surrounding villages. Lavenham-style timber framing needs specialist scribed repair, not replacement. Because dry easterly climate with strong coastal salt exposure, we allow for it at survey stage rather than discovering it on the day.
Can you work on a listed building?
Yes, and a significant share of our work is listed or conservation area. We can supply drawings and section details to support a listed building consent or planning application, though the consent itself remains the owner's responsibility.
Can you match an existing profile?
Yes. If you can supply a section, a photograph with a rule in shot, or an old unit, we can replicate the profile. For conservation work this is usually the condition the planning officer will apply.
Do you deliver nationwide?
Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.
What guarantee do you provide?
Ten years on workmanship, covering manufacture and the factory-applied finish. Where we install, the installation is covered too. It is issued in writing with the handover paperwork.
