Questions
Do you take away the old windows?
Yes. Removal and responsible disposal are included, along with making good internally. We work one opening at a time so the property is never left open, and we clear the site each day.
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.
