Berkhamsted, Hertfordshire
Hardwood Sash Windows in Berkhamsted
Weighted box sash and spiral-balance sash windows made from kiln-dried hardwood, with authentic sightlines and modern draught sealing.
Berkhamsted has a housing stock that punishes off-the-shelf joinery — openings settle, reveals go out of square, and cills rarely sit level. Bespoke hardwood sash windows solve that properly.
What is included
- Warm-edge spacer bars as standard, which cut the cold bridge at the glass edge and reduce condensation.
- Compression seals rather than brush pile where the design allows, for a measurably tighter close.
- FSC-certified hardwood with documented chain of custody, available on request for planning submissions.
- Warm-edge spacer bars as standard, which cut the cold bridge at the glass edge and reduce condensation.

Questions
How much disruption should I expect?
Less than most people fear. A straightforward replacement is one opening at a time, typically two to four windows a day. Scaffolding is only needed on higher elevations. We protect floors and furniture and leave the site clean each evening.
How long do hardwood windows actually last?
Properly specified and maintained hardwood joinery has a realistic service life of 60 years or more. The timber is rarely what fails — it is the finish and the seals, and both are renewable. That is the fundamental advantage over uPVC, where a failed unit or a distorted frame means the whole window goes.
Are timber windows warm enough for Building Regulations?
Yes, comfortably. Timber is a natural insulator with far lower conductivity than aluminium or steel. A standard hardwood double-glazed window achieves around 1.2–1.4 W/m²K whole-window, against a 1.4 requirement for replacements. Triple glazing in a deeper section will reach roughly 0.8.
Can I have double glazing in a conservation area?
Usually, yes — using slim-profile sealed units as narrow as 11mm, which fit within traditional glazing bar sections without fattening them. Conservation officers vary, so we specify from the outset to whatever the local authority has stated and provide section drawings for the application.
