Whole-house triple glazing
Doing the whole house at once gives you one survey, one set of access equipment, matching frames and one handover pack for the whole house. It also lets us plan ventilation and escape windows across the house rather than room by room.
Summary
Whole-house triple glazing means replacing every window, and usually the external doors, in one job. On our guide, a typical 3-bed semi with 9 windows and a front door costs £9,395 to £11,795 to triple glaze in white uPVC, inc VAT, and usually takes 2 to 3 days on site.

Is a whole-house upgrade worth it?
If you are replacing single glazing or failing double glazing, yes: the savings, comfort and condensation benefits are real. If your double glazing is modern and sound, the extra energy saving from going triple is small, far less than replacing single glazing, so the case rests on comfort and noise rather than bills. We will tell you which applies to your house.
Planning the job
We sequence the rooms so the house is never left open overnight, protect floors and furniture, and make good the reveals as each window goes in. You get the guarantees and handover pack at the end, with Building Regulations sign-off where your nation requires it.
