Replacement Windows fitted in Kettering
How do you know your windows have had their day? Handles that need a shove, hinges that drop, seals gone hard and black, or a sash that no longer closes flush are the usual signs. On many Kettering estates, those early uPVC frames are now old enough to be showing all of them.
Replacing windows is a job that goes well when it is planned properly, so we begin with a survey at your home. Then we make the new frames to measure at our Saffron Lane factory in Leicester, around 22 miles away, and our own installers bring them to you. Old frames come out, new ones go in, and the openings are finished neatly before the team moves to the next room. We have been doing this for nearly 40 years. Being FENSA approved means we self-certify the work, and a certificate comes to you afterwards. Ring 0116 283 1010 to book your survey.

Which replacement windows suit Kettering homes?
A replacement does not have to copy the old window. Look at what the house was built with, then decide what is worth bringing back. Many of the red-brick terraces lost their original style when plain frames went in decades ago, and a flush casement or sliding sash can restore some of that character. On a 1930s semi, check whether the top lights were once leaded before choosing a plain pane. Newer homes are simpler, and a straightforward casement often does the job. Think about which panes really need to open as well. Changing the layout at replacement stage can make cleaning easier, and upstairs windows may need to work as an escape route.
Our Work
A few of the jobs we have fitted for our customers.
Planning and building regulations in Kettering
Swapping worn-out windows for similar new ones on a house is usually permitted development. A very different look may raise questions, especially for a flat, a listed building or an address within the Kettering Town Centre Conservation Area. North Northamptonshire Council is the place to check. Building Regulations still apply to every replacement, covering matters such as energy performance and escape from upper floors. Our FENSA approval lets us self-certify, so your certificate shows compliance when you come to sell.
Replacement Windows in Kettering: your questions answered
How much mess does replacing windows make?
Some dust is unavoidable when an old frame comes out, particularly from older plaster around the opening. Our installers work room by room, so the disruption moves through the house instead of affecting everything together. Clearing sills and moving furniture back from the windows before they arrive helps. At the survey we can point out any rooms needing extra care.
Can you just replace the glass instead of the whole window?
Often, yes. If the frame is sound and only the sealed unit has misted, new glass may be all you need. When the frame itself has warped, the hinges have dropped or the locks are worn, a full replacement usually makes more sense. We will look at both on our visit and tell you which we think is right.
What paperwork should I keep after my windows are replaced?
Keep your FENSA certificate with the house documents, as a buyer's solicitor will commonly ask for it when you sell. It shows the replacement windows meet Building Regulations, so nobody needs to chase North Northamptonshire Council's building control for evidence later. If you misplace it, get in touch and we will point you in the right direction.
