Slim Cavity Glazing across South Yorkshire
Slim Cavity Glazing is one of those jobs in South Yorkshire where the survey decides everything. You are mostly dealing with steel-era terraces, interwar council stock and stone village housing around here, so openings vary more than people expect. Because of cold inland winters with prolonged damp, we see condensation-driven decay on single-glazed units in unheated rooms more often here than in most of the country. Everything we do here comes back to getting a sealed unit into a historic sightline without bulking it out.
Nothing goes into manufacture until a surveyor has checked each opening on site. Give us the basics and you will have a written figure, not a range that moves later.
A detail specific to this area: large volumes of pre-1919 stock make sash repair the dominant enquiry.

Frequently asked questions
Do you cover South Yorkshire?
Yes. We cover the whole of South Yorkshire including Sheffield, Doncaster, Rotherham, Barnsley and the surrounding villages. Large volumes of pre-1919 stock make sash repair the dominant enquiry. Because cold inland winters with prolonged damp, we allow for it at survey stage rather than discovering it on the day.
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.
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 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 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.
