Timber glazing upgrades in Bletchley
Draught Sealing is one of those jobs in Bletchley where the survey decides everything. You are mostly dealing with Chiltern brick-and-flint cottages alongside large modern estates around here, so openings vary more than people expect. What accelerates it is chalk-valley damp with cold air pooling overnight, and persistent condensation staining and cill rot on older single-glazed units follows sooner than owners expect. The part that matters is sealing the perimeter without making anything stiff to open.
Nothing is ordered until someone has stood in front of the opening with a tape. One call is usually enough for us to tell you roughly where the price will land.
Worth knowing locally: AONB designation across much of the county tightens external alteration consent.

How long does a typical order take?
Most made-to-size orders run six to ten weeks from survey to delivery. Conservation and heavily detailed work can take longer, and we confirm the lead time in writing at quotation rather than leaving it open.
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.
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.
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.
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.
