Timber glazing upgrades in Horsham
If Secondary Glazing in Horsham were straightforward, there would be a stock size for it. Local stock is dominated by Sussex flint cottages, Regency seafront terraces and postwar new town housing, which sets the sizes and profiles we work to. Set against strong coastal exposure with salt spray inland of the shoreline, most joinery here eventually shows finish erosion on seaward elevations within a few years of coating. The value is in internal glazing that leaves the original window entirely untouched, not in the timber bill.
The survey happens before manufacture, which is why our units fit without packing or trimming. Send what you have, even if it is only a phone photo, and we will take it from there.
Local factor worth flagging early: seafront properties need a shorter recoating cycle than inland equivalents.

“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.
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.
Do you take a deposit?
Not before the measured survey. A deposit is only requested once the survey is complete and you have approved the final schedule and price.
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.
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.
