Timber glazing upgrades in Desborough
If you are looking at Retrofit Double Glazing in Desborough, the timber is only half the decision. Because the area is mainly ironstone cottages, boot-and-shoe terraces and new town expansion housing, no two openings measure quite the same. Add dry inland conditions with limited coastal influence to that and seasonal shrinkage and glazing bead loosening on older painted units becomes the usual trigger for replacement. The value is in reworking the rebate so a sealed unit fits without bulking the section, not in the timber bill.
The site visit comes first, because assumptions made in an office get paid for 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.

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.
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 fit, or supply only?
Both. Supply-only is common for trade and contractor clients. For private clients we usually recommend supply and fit, because responsibility for the fit and the finish then sits in one place.
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.
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.
