What we fit
Installations and repairs, start to finish.
In one customer's words, the firm is the one to call for windows, doors, bi-folds, patio doors, fascias and gutters. Here is what that covers.
Front doors
Front doors fitted, with the old door and frame taken away. When one customer wanted a very specific door, Paul and Daniel went and found it.
Patio and French doors
A dining room window taken out and a patio door fitted in its place. French doors added to a bay window so neatly the owner says they look like they have always been there.
Bi-folds
Bi-fold doors are on the list of work customers recommend the firm for, alongside windows, doors and patio doors.
Fascias and gutters
Fascias and gutters, so the roofline can be done by the same firm that did the windows.
Plastering and finishing
The plastering and finishing inside is done by the firm too. A customer who manages properties says every job is left fully completed, with no loose ends.
Front doors
If the door you want is hard to find, they will find it.
One family had a very particular front door in mind and asked Paul and Daniel to track it down. This is how they describe what happened next.
“After months of looking and research they found the perfect door for us and as always fitted it to perfection…”
Recent work
Brick, render and stone. White frames and black.

Absolutely fantastic service! I contacted Paul on behalf of a family member - his expertise and advice was second to none. From the initial quote Paul and his son have been excellent and pleasure to deal with. The fitting of the windows have been done to a very high standard - what a difference to the appearance of the house! Thank you again for all your hard work

Used Paul first time 16 years ago...he was that good I kept his details should we need him in the future. Moved house and decided to add french doors to a bay window. Such a nice job, looks like they've always been there! Reliable, tidy and respectful and above all good quality windows and workmanship. Highly recommend +++

I’ve worked with Paul and Daniel for many years, and the quality of their work is second to none. They’ve completed projects on my own home, properties belonging to my clients, and multiple properties I manage professionally — and every job has been completed to an exceptional standard. If you’re looking for first-class workmanship, I can highly recommend Knowsley Windows. Paul, Daniel, and the team consistently go above and beyond from start to finish. What really sets them apart is that they don’t just install windows and doors — they also carry out the plastering and finishing work internally, leaving every job fully completed to a high standard with no loose ends. Professional, reliable, and genuinely top-quality craftsmen, and genuine people.

Fantastic service again from Paul and Daniel @Knowsley Windows. We and friends/family have used them on numerous occasions but our last experience topped them all. We gave them the difficult task of finding a very specific door that we really wanted. After months of looking and research they found the perfect door for us and as always fitted it to perfection with a clean and tidy installation and taking away our old door and frame. We are over the moon with our new front door and have had lots of comments on it also from friends, family and neighbours. Would highly recommend Knowsley Windows for all your Windows, doors, bi-folds, patio doors, fascia’s and gutters. 5* service every time and they go above and beyond. Thanks again Paul and Daniel 😀
