Timber glazing upgrades in Corby
Ask three firms about Secondary Glazing in Corby and you will get three different answers. Around here it is ironstone cottages, boot-and-shoe terraces and new town expansion housing, and that alone rules out anything bought by the pallet. With dry inland conditions with limited coastal influence in the mix, seasonal shrinkage and glazing bead loosening on older painted units is a question of when rather than whether. What we concentrate on is internal glazing that leaves the original window entirely untouched.
A surveyor visits first and records the real dimensions, at several points on each opening. Ask us for a figure and you will get one, with the lead time stated alongside it.
Worth knowing locally: ironstone reveals absorb water and hold it against frames in wet spells.

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

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 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.
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.
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.
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.
