Timber glazing upgrades in Berkhamsted
People come to us about Draught Sealing in Berkhamsted once the cheap option has already failed. Local property is overwhelmingly garden city stock, Georgian market town frontages and commuter-belt detached housing, which is why we never quote from a catalogue. Then there is moderate rainfall with cold inland frosts, which reliably produces frost damage to end grain and swelling on unbalanced-finished units given enough seasons. The value is in sealing the perimeter without making anything stiff to open, not in the timber bill.
Nothing goes into manufacture until a surveyor has checked each opening on site. A quick call or a photograph of the opening is usually enough to get you a price.
Local factor worth flagging early: garden city areas carry design codes that restrict window style changes.

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

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.
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.
How do you handle glazing?
Standard double glazed units for most work, and slim-cavity units where a conservation officer has restricted sightlines. Single glazing with putty lines is available where the consent requires it.
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 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.
