Timber glazing upgrades in Irthlingborough
Half the Draught Sealing problems we fix in Irthlingborough started as a sizing assumption. The building stock is ironstone cottages, boot-and-shoe terraces and new town expansion housing, so we expect variation before we ever pick up a tape. Set against dry inland conditions with limited coastal influence, most joinery here eventually shows seasonal shrinkage and glazing bead loosening on older painted units. The part that matters is sealing the perimeter without making anything stiff to open.
A surveyor visits first and records the real dimensions, at several points on each opening. Tell us what you are working with and we will put a fixed figure in writing.
One thing that catches people out here: 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.”

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.
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.
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.
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.
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.
