Timber glazing upgrades in Hanham
Nothing about Slim Cavity Units in Hanham is settled until someone has been on site. Local stock is dominated by Georgian Clifton terraces, Victorian bay-fronted streets and converted warehouses, which sets the sizes and profiles we work to. Locally you are contending with mild wet westerly weather with limited hard frost, so moss and algae growth followed by paint blistering on shaded elevations is the fault we are called out to. The detail we will not compromise on is narrow cavities that perform while keeping the sightline historic.
Every job is measured on site first, because drawn sizes and built sizes are seldom the same. Photographs and approximate sizes are all we need to start.
Worth knowing locally: Clifton's Georgian stock frequently requires exact sash box replication.

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

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.
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.
