Timber glazing upgrades in Newhaven
Slim Cavity Units around Newhaven is a different job from one street to the next. The building stock is Regency bows and bays, weatherboarded cottages and cliff-top villas, so we expect variation before we ever pick up a tape. Then there is severe salt exposure combined with strong UV on south-facing frontages, which reliably produces UV breakdown of clear finishes and rapid degradation of putty lines given enough seasons. The value is in narrow cavities that perform while keeping the sightline historic, not in the timber bill.
The site visit comes first, because assumptions made in an office get paid for on site. Send what you have, even if it is only a phone photo, and we will take it from there.
A local consideration we always raise: Regency bow windows demand curved-glass and matched-profile joinery.

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

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.
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.
