Timber glazing upgrades in Sawston
Misted Unit Replacement in Sawston rewards patience at the setting-out stage. The housing here is largely college-town Georgian stock, fenland brick farmhouses and rapid new-build growth, and that shapes what will actually fit. Locally you are contending with the driest region in the UK with exposed fen wind, so shrinkage and joint opening rather than rot in most inland stock is the fault we are called out to. In practice that means swapping the failed unit rather than selling you a whole window.
Nothing is ordered until someone has stood in front of the opening with a tape. Tell us the problem rather than the solution and we will advise on both.
Worth knowing locally: college and listed stock in Cambridge demands exact historic replication.

“The survey showed most of the loss was around the frames, not through the glass at all.”

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.
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.
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.
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.
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.
