Timber glazing upgrades in Bishop's Stortford
There is no standard version of Trickle Vents and Ventilation in Bishop's Stortford, which is rather the point. Given the garden city stock, Georgian market town frontages and commuter-belt detached housing that dominates locally, standard sizes are the exception not the rule. Locally you are contending with moderate rainfall with cold inland frosts, so frost damage to end grain and swelling on unbalanced-finished units is the fault we are called out to. The detail we will not compromise on is keeping background ventilation compliant once you seal a house up.
We survey before anything is cut, so the schedule reflects the opening as built rather than as drawn. Give us the basics and you will have a written figure, not a range that moves later.
A local consideration we always raise: garden city areas carry design codes that restrict window style changes.

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.
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.
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.
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.
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.
