What we do and how we do it
People come to us about Secondary Glazing in the UK once the cheap option has already failed. You will find mostly a mix of period and modern stock in this area, and it moves as it ages. Because of the full range of UK exposure conditions, we see coating failure followed by rot at the joints more often here than in most of the country. Everything we do here comes back to internal glazing that improves comfort without touching the original.
The measuring is done by the people responsible for the fit, which concentrates the mind. Give us the basics and you will have a written figure, not a range that moves later.
One local point to factor in: specification should always be matched to local exposure.
Specification
- Engineered hardwood or slow-grown softwood, FSC certified
- Factory-applied microporous finish in any RAL or heritage colour
- Sealed units, slim-cavity units or single glazing with putty line
- Manufactured to survey dimensions, not to a stock size chart
- Delivered UK-wide with chain-of-custody paperwork
Repair before replace
If the original timber is sound we keep it. It is cheaper and it is better.
Draughts and rattle gone
Brush seal systems that stop movement without making the sash stiff.
Honest condition survey
Including telling you when a window is genuinely beyond saving.
Most work in a day
Draught proofing and cord renewal are usually same-day, room by room.

Frequently asked questions
Can you price from drawings?
Yes. Send a drawing set or a schedule and we will price against it. If anything is ambiguous we will query it before quoting rather than assume and reprice later.
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.
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.
