Timber glazing upgrades in Kettering
The hard part of Slim Cavity Units in Kettering is not the making, it is the measuring. With ironstone cottages, boot-and-shoe terraces and new town expansion housing making up much of the area, off-the-shelf sizes rarely line up. Locally you are contending with dry inland conditions with limited coastal influence, so seasonal shrinkage and glazing bead loosening on older painted units is the fault we are called out to. This is really a job about narrow cavities that perform while keeping the sightline historic.
We check on site before committing anything to the saw, and we query what does not add up. Give us the basics and you will have a written figure, not a range that moves later.
A detail specific to this area: ironstone reveals absorb water and hold it against frames in wet spells.

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.
How do you handle glazing?
Standard double glazed units for most work, and slim-cavity units where a conservation officer has restricted sightlines. Single glazing with putty lines is available where the consent requires it.
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.
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.
