Extending, converting the garage or taking a tired house back to brick. The glazing decides how the finished room feels, and when it turns up decides how smoothly the build runs. We fit windows, doors, bi-folds and lantern roofs for projects across Weston-super-Mare, North Somerset and Somerset.

We Work to Your Builder's Dates

We come out early, agree sizes and positions with your builder, and book a fitting date that suits the programme. One person measures, orders and fits, so when the dates move there's nobody to chase. Your builder gets a straight answer and you get one less thing to project manage.

What We Fit on Extension Projects

Windows in any style to match the rest of the house, bi-fold, patio and French doors onto the garden, a composite back door, and a lantern roof to bring daylight into the middle of the new room. If the existing windows are tired, it's often the right moment to do the whole house at once so everything matches.

Matching the Rest of Your House

A new extension looks like an afterthought when the glazing doesn't match. We match the style, colour and finish of your existing windows, or replace the lot so the whole house finally agrees with itself.

Measure Early, Fit on Time

Glazing is made to measure, so the lead time sits between the brickwork going up and the room being usable. Talk to us at the planning stage and we'll tell you when we need final sizes, which keeps the build moving.

  • A. Speak to us at the planning stage so sizes and positions are agreed before the brickwork goes up. We take the final measurements once the openings are built, then order and fit to the date your builder needs.

  • A. Yes. We match the style, colour and finish of your existing windows so the extension looks like part of the house

  • A. Windows and doors in a new extension are signed off as part of the Building Regulations approval for the build itself. Replacement windows in the existing house are registered with FENSA by us, and you'll get the certificate.
