Full-Frame Window Installation Questions

The old window and its frame are fully removed, the opening is inspected for rot, damp and structural movement, and a completely new frame and window are fitted and sealed. It is more involved than fitting a new window into the existing frame, but it addresses problems a simpler job would leave behind.

Not necessarily. The condition of each opening determines the right approach. Where the existing frame is still sound, a pocket insert may be sufficient. Where there is rot, damp or a failing seal around the frame, full removal is the better option. The survey identifies which applies to each window.

Rot in a timber frame spreads into the surrounding structure over time. What starts as a localised sill problem can reach the lintel or internal wall, making the eventual repair significantly more involved and more expensive than addressing it at the window stage.

Removing the old frame takes more labour than leaving it in place, and any remedial work to the opening adds to the time on site. Materials cover the full frame assembly, not just the glazed unit. The itemised quote sets out each element so you can see where the cost sits.

Yes. Window installation in England is notifiable work under Building Regulations. The installer must either apply for a Building Regulations notice or self-certify through a scheme such as FENSA. The local installers we connect you with handle FENSA self-certification as part of the job.

A straightforward opening with no remedial work typically takes a few hours per window. Openings with rot, damp or structural issues take longer. Whole-house programmes are scheduled to keep disruption manageable, and the quote will indicate the expected time on site for your specific job.
