What Our Customers Say
Rated 5.0 ⭐ on Google by homeowners across Kent & Medway
I would highly recommend this company and would consider them for any future installation.
The company clearly cares about their customers and ensure they do an excellent job.
Would highly recommend Kent Window Wizard
Jake was courteous, knowledgeable and clearly takes pride in his work. It is reassuring to know there are still tradespeople out there who care about doing things properly. I would not hesitate to recommend Kent Window Wizard to anyone needing reliable, top-quality service.
Thank you, Jake — a true professional!
We are very happy with the work and will be using Kent Window Wizard in the future if we need any further window/door work.
He was extremely friendly, reliable and very professional. I was fitted into his already busy schedule. It was such great service I have now asked him to complete further work and will be using his services again.
I would highly recommend him if you are looking for any windows or doors.
We had the new door fitted today and we are extremely happy with it. It has completely transformed the front of the house.
We also were wondering if it was worth renewing some of the windows in the house. Upon looking at them Jake has advised that it would be a better option to fix them rather than renew. Many other companies may have just agreed to renewing the windows knowing full well they could be repaired and be as good as new.
Honest, reliable and affordable. Couldn’t ask for more.
He came out to fix a number of things today.
Jake sorted out my front door in no time!
He also fixes 2 windows.
He is brilliant at his job very knowledgeable in his field.
a lovely friendly man also!
Would recommend to everyone I’m gutted I never found him sooner.
(I have gad 2 other people look at my front door they couldn’t fix it Jake did it in half an hour it’s now good as new!)
Thank you very much!
Sent an enquiry via the website on Sunday and got a reply same day with a very reasonable quote (fixed cost per hinge replacement). Was able to attend Monday and fixed multiple windows for me.
I would recommend to other landlords.
Very prompt service & friendly staff 🙂
Thank you so much, for the outstanding difference you both made to our home, at such a fantastic price. Really appreciate all your hard work. It was a massive saving on time, stress & money repairing what we had, especially when we were worried that we’d have to replace it all.
Now we have easy use of the windows where you replaced broken hinges now means a lot more comfort in this hot weather & the visual difference made with the replaced glass units & removed false leading, it’s absolutely awesome.
I’m happily asking Kent Window Wizard back to work their magic again, for a full window service, the work they did last weekend put them firmly on my trusted traders list.
Highly recommend 👌 👍

What types of window and door installations do you offer?
We offer full installation of uPVC and aluminium windows including casement, sash, bay, and tilt-and-turn styles. For doors, we install composite front doors, bi-fold doors, French doors, patio doors, and stable doors. All products are available in a wide range of colours and finishes to suit your home.
Which areas in Kent and Medway do you cover?
We cover the whole of Kent and Medway, including Chatham, Maidstone, Rochester, Gillingham, Sittingbourne, Faversham, Tonbridge, Tunbridge Wells, Canterbury, Gravesend, and all surrounding towns and villages. Not sure if we cover your area? Give us a call on 01634 944 243.
Do you offer a guarantee on new installations?
Yes — every installation we complete comes with a 10-year insurance-backed guarantee. This is issued by an independent insurance provider, meaning your guarantee remains valid even if circumstances change. The guarantee is also fully transferable if you sell your home, adding value for future buyers.
How much does it cost to have new windows or doors installed?
Costs vary depending on the number, size, style, and material of the windows and doors. Use our free instant quote tool at the top of this page to get a price range in under 60 seconds. For a more detailed conversation, you’re welcome to call us on 01634 944 243 — there’s no obligation to proceed.
How long does a typical window or door installation take?
Most full-home window installations are completed in a single day. Larger properties or more complex door installations (such as bi-folds) may take one to two days. We’ll always give you a realistic timescale when we carry out your free home survey.
Are your window and door installations energy-efficient?
Absolutely. All of our windows and doors carry an A or A+ energy efficiency rating, which significantly reduces heat loss through your home’s openings. Many of our customers notice a meaningful reduction in their heating bills after installation, and modern glazing also reduces external noise and condensation.
How do I get started with a new installation?
The easiest way is to use our free instant quote tool at the top of this page — it takes under 60 seconds and gives you a guide price with no commitment. We’ll then be in touch to arrange a free home survey at a time that suits you. Alternatively, you can call us directly on 01634 944 243 and we’ll talk you through your options.
