Slim Cavity Units across Norfolk
If Slim Cavity Units in Norfolk were straightforward, there would be a stock size for it. You will find mostly flint and pantile cottages, Georgian merchant houses and coastal resort stock in this area, and it moves as it ages. The other factor is exposed North Sea easterlies with salt-laden wind, which is why salt damage and finish erosion on east-facing coastal elevations is the most common reason people call us. Everything we do here comes back to narrow cavities that perform while keeping the sightline historic.
Nothing goes into manufacture until a surveyor has checked each opening on site. Rough dimensions and a couple of photographs are enough for us to price it properly.
Worth knowing locally: flint walls give minimal reveal, so weathering detail carries the whole load.

Frequently asked questions
Do you cover Norfolk?
Yes. We cover the whole of Norfolk including Norwich, Great Yarmouth, King's Lynn, Thetford and the surrounding villages. Flint walls give minimal reveal, so weathering detail carries the whole load. Because exposed North Sea easterlies with salt-laden wind, we allow for it at survey stage rather than discovering it on the day.
What if the opening is out of square?
Most older openings are. The survey records the actual dimensions at several points and the unit is manufactured to suit, which is the main reason we survey rather than work from the sizes given over the phone.
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 deliver nationwide?
Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.
Will the finish need maintaining?
A factory-applied microporous finish typically needs inspection every three to five years, sooner on exposed coastal elevations. Maintaining it is far cheaper than letting a coating fail and the timber take up water.
