Timber glazing upgrades in Croydon
The hard part of Retrofit Double Glazing in Croydon is not the making, it is the measuring. Most of what we survey locally is Victorian and Edwardian terraces, mansion blocks and post-war infill, which is not built to any modern module. high pollution load and sheltered urban humidity is the local complication, and paint failure on south-facing sashes and rot at the bottom rail is what it eventually causes. In practice that means reworking the rebate so a sealed unit fits without bulking the section.
Each opening is recorded individually, since a terrace of identical houses rarely is. We will price it properly in writing, and we will tell you if it is not worth doing.
One thing that catches people out here: large numbers of properties sit in conservation areas with like-for-like replacement conditions.

“The survey showed most of the loss was around the frames, not through the glass at all.”
Verified client, Greater London“Half the cost of replacement and the rooms hold heat noticeably better.”
Verified client, Greater London“They fitted trickle vents we had not thought about, which stopped the condensation.”

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.
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.
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.
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.
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.
