Timber glazing upgrades in Thrapston
Getting Thermal Survey right in Thrapston depends on detail that a price list cannot capture. The housing here is largely ironstone cottages, boot-and-shoe terraces and new town expansion housing, and that shapes what will actually fit. The weather does the rest: dry inland conditions with limited coastal influence here, and seasonal shrinkage and glazing bead loosening on older painted units as the predictable result. Where we put the effort is measuring where heat is going before anyone recommends a spend.
Nothing goes into manufacture until a surveyor has checked each opening on site. Photographs and approximate sizes are all we need to start.
Local factor worth flagging early: ironstone reveals absorb water and hold it against frames in wet spells.

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.
