FAQs

Do I need to remove my blinds?

If blinds are fitted to the window being replaced they will need removing. If you need any help with this please let us know in advance.

Do I need to put dust sheets down for a window installation?

No, we will bring our own sheets and clean up after ourselves.

Does changing my windows make much mess?

There is obvious disruption when changing windows but when finished, your home should be as clean and tidy as we found it.

I have alarm points on my windows, do they need moving?

Every alarm system is different, most points will transfer over with ease but please be sure to point out your alarm points and ask so we can give you a better evaluation once viewed.

Will changing my bathroom window damage tiles?

Most windows can be changed without any damage to tiles but it can depend on the age and condition of the tiles around the window.

Do you need to trim the inside of windows?

We try and leave installations with no extra work for you to do once finished, which is where internal trims help. If you don’t like internal trims ask us about different options.

Do I have to have trickle vents on my new windows?

Yes, all new windows now come with trickle vents to comply with current building regulations.

I couldn’t be happier with the service and quality from K and M Installs Ltd. K & M Installs have just fitted a full house of windows for us, back and front, plus new front door and side door (in just 3 days!) and we couldn’t be happier with the service and quality of workmanship. Kris was patient and helpful during the design stage, very responsive throughout, and his team were hard working, really friendly and went above and beyond during the installation. I wouldn’t hesitate to recommend K & M Installs.

Google review, 5 stars

I cannot thank Kris and his lads enough that came to fit the new bathroom window and bedroom window on 20/11/25. From the very outset Kris’ company was professional. A huge tick returning my call to get a quote. Second big tick actually turning up when Kris said he would. And the biggest tick was the fitters. Not only did they arrive on time. They treated our house like it was their own home. Covered everything (I had just had new carpets fitted) cleaned up after they had finished, actually leaving the two rooms cleaner than when they first started. Their workmanship was immaculate. I cannot sing their praises enough. Please do approach this company for a quote and their work. You will not be disappointed. I would highly recommend them. Thank you again Kris and the lovely lads that came to fit.

Trustpilot review, 5 stars

Used K&M for all our replacement windows and now for the install of patio doors. Looks incredible, so happy with it. Install team were great, a credit to the company. Pleasant to have in your home and worked hard to clean up & finish it all to a top standard.

Yell.com review, 5 stars

I had K and M Installs back to do the work because I was very happy with the previous work that they did replacing some windows. I chose them via a recommendation and am confident to recommend them to family and friends. They are professional, pleasant to work with and I think reasonably priced to offer a good product. My house is now far more effective in retaining heat. Thank you K and M for a smooth experience.

Rated People review

We would highly recommend K and M Installs. All the way through the process of obtaining a quotation to installation of new windows and doors, they were very professional. Nothing was too much trouble even when we asked them to do additional work. Very competitive pricing too. It is now two weeks since all the work was completed and we have received so many compliments. Looks like a brand new house. Thank you Kris to you and your team.
