Timber glazing upgrades in Northampton
We take a fair volume of Retrofit Double Glazing work across Northampton, and almost none of it repeats. You are mostly dealing with ironstone cottages, boot-and-shoe terraces and new town expansion housing around here, so openings vary more than people expect. Then there is dry inland conditions with limited coastal influence, which reliably produces seasonal shrinkage and glazing bead loosening on older painted units given enough seasons. Everything we do here comes back to reworking the rebate so a sealed unit fits without bulking the section.
Manufacture only starts once the survey figures are agreed with you in writing. Get in touch and we will be straight with you about cost and timescale.
Local factor worth flagging early: 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 work on a listed building?
Yes, and a significant share of our work is listed or conservation area. We can supply drawings and section details to support a listed building consent or planning application, though the consent itself remains the owner's responsibility.
Do you work in hardwood or softwood?
Both. Engineered hardwood is the default where movement or exposure is a concern, and slow-grown softwood is often the better value choice for painted work in sheltered positions. We will tell you which we would specify and why.
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.
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.
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.
