Timber glazing upgrades in Guildford
Most Retrofit Double Glazing enquiries we take in Guildford start with an opening that is not a standard size. With interwar detached stock, Arts and Crafts houses and 1930s semis making up much of the area, off-the-shelf sizes rarely line up. Then there is mild but damp, with heavy tree cover holding moisture against elevations, which reliably produces sap staining and green growth on north elevations followed by joint opening given enough seasons. The detail we will not compromise on is reworking the rebate so a sealed unit fits without bulking the section.
Nothing is ordered until someone has stood in front of the opening with a tape. Photographs and approximate sizes are all we need to start.
Local factor worth flagging early: high-value stock where owners specify hardwood over softwood as standard.

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

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.
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.
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.
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.
Is the timber certified?
All our stock is FSC certified and chain-of-custody documentation is supplied with the order, which most main contractors and specifiers now require for their records.
