Old windows letting in draughts, noise or damp? Glitz Windows supplies and fits uPVC windows across Surrey and South London, made to measure and installed by experienced fitters. Whether you need one replacement or a full house refit, you’ll get a straight answer and an honest quote, with no pressure and no jargon.
If your windows are draughty, discoloured or just won’t open properly any more, you’re not imagining it. uPVC frames wear over time, especially in older homes around Surrey and South London that still have the same windows after 20 years or more.
We’d rather talk you through what actually needs doing than sell you the biggest package we can. Sometimes that means replacement uPVC windows. Sometimes a repair is all you need. We handle the whole job either way: survey, manufacture, fitting and the paperwork that comes with it.
uPVC stands for unplasticised polyvinyl chloride. It’s a tough, weather-resistant plastic that’s used to make window frames instead of timber or aluminium. It doesn’t rot, it doesn’t need repainting, and it holds its shape in conditions that would warp or split wood.
uPVC has been used in British homes for decades because it’s affordable, energy-efficient and long-lasting. A well-fitted set of frames can last 25 to 30 years.
A worn or poorly sealed window is one of the quickest ways to lose heat, however good your boiler is. Modern uPVC windows with low-E double glazing keep the warmth in, and depending on what you’re replacing, you may notice a real drop in your heating bills. Most people feel the difference in the first cold snap.
Our uPVC windows come with multi-point locking, so the frame is secured in several places instead of relying on one latch. Add reinforced frames and toughened glass options, and it’s a big step up from older single-lock windows.
No sanding, no repainting, no filling cracks where the timber has swollen. A wipe-down now and then is all a uPVC frame needs. That’s a big reason they’ve stayed so popular. Nobody wants to repaint window frames every few summers.
If you live on a main road in Croydon, near the railway in Sutton, or anywhere with more traffic than you’d like, this matters. uPVC frames with double or triple glazing won’t silence the outside world, but they’ll take the edge off it. You’ll notice the first evening you sit in the room with the windows shut.
The most common style in the UK, and for good reason. They’re practical, affordable and suit almost any property. They hinge at the side, open outwards and are easy to clean from inside.
These open inwards in two ways: tilted from the top for gentle ventilation, or swung fully open on a side hinge for cleaning. They’re a good fit for flats and upper floors, where safety and easy cleaning both matter.
A bay or bow changes the feel of a room. It pushes the space outwards and lets in more daylight, and it’s one of the most noticeable upgrades you can make to the front of a house.
If you have a period home and love the classic vertical-sliding look, uPVC sashes give you that without the draughts and rot of old timber. They’re popular in parts of Surrey with older, character housing, where planning rules sometimes apply.
A more contemporary take, with the sash sitting level with the frame. It’s a good choice if you want the character of timber windows with the low maintenance of uPVC.
Good windows only perform if they’re fitted well. That’s why we look after every step of uPVC window installation ourselves.
We come out, look at what you have and talk through your options honestly, including telling you if you don't need a full replacement. You get a clear quote with nothing vague hidden in the small print.
Every window is made for your specific openings, not a standard size. It matters more than people think. A badly fitted window undoes most of the energy and security benefits you're paying for.
Our installers remove your old windows, fit the new ones, and seal and finish everything properly, so there's no draught creeping in round the edges months later.
Once we've finished, you're covered by our guarantee. If something isn't right, we come back and sort it. We're not a company that disappears once the invoice is paid.
Not every window problem means starting again. If your frames are still in decent shape, uPVC window repairs can save you a lot of money, and we’ll tell you honestly which route makes sense.
Here’s what we can usually put right:
If you’re wondering whether to repair uPVC windows or replace them, the frames are the deciding factor. If they’re warped, cracked or badly discoloured, replacement will usually be better value in the long run. If it’s just the glass or hardware, repair is often the smarter move. We’ll take a look and give you a straight answer.
Choosing an installer matters as much as choosing the windows. Even a well-made window needs careful measuring, correct fitting and a proper finish to do its job.

Adeel was able to visit quickly and offered great advice on a new door and a replacement window panel. Competitive quote and speedy straightforward ordering process. Fitter was fantastic and we’re really pleased with the installation. Wouldn’t hesitate to recommend or use again.Posted on Google Mel BakerTrustindex verifies that the original source of the review is Google. Adel was a delight to work with. He listened, made helpful suggestions and asked lots of questions to make sure he knew what we wanted. He measured twice (at least)and kept us in the loop about delivery and instalment. During instalment he came several times a day to check on progress and was always very responsive to any messages or queries from us. Even when there was a problem with some debris left on site after completion, he sorted the issue within half a day. Highly recommended.Posted on Google Alexander CooperTrustindex verifies that the original source of the review is Google.

Fantastic service provided by Adel and his team! Highly recommend! Great communication at all times and very helpful. I'm very happy with the windows and bifold doors provided.Posted on Google john ambrosTrustindex verifies that the original source of the review is Google. I recently had all nine windows replaced by Glitz Windows and couldn’t be happier with the overall service. Our existing windows were very old and had reached the point where they really needed replacing, so we decided it was time to invest in new ones. The difference they have made to the property is incredible. Adel was fantastic throughout the whole process. Communication was clear from the beginning, he kept me updated at every stage and was always available to answer any questions. The quotation was very competitive, and I never felt under any pressure. Once everything was agreed, the installation was arranged promptly. The fitters were polite, professional and worked incredibly efficiently. We expected the installation to take around three days, but they completed everything in just two days while maintaining a high standard of workmanship. The new windows have completely transformed the look and feel of the property, and I’m really pleased with the finished result. If you’re looking for a company that offers excellent communication, competitive pricing and quality workmanship, I would definitely recommend Glitz Windows.Posted on Google Jason VASANTrustindex verifies that the original source of the review is Google. We needed windows changed at our home as it had been 25 years since we moved in... and glitz windows came over. Helpful and informative staff... brought samples and explained all our options. Eventually after comparing prices with other companies we decided to go with them. And I must say they did an amazing job. Always available on WhatsApp to explain delivery dates and answer any questions I may have had prior to installation. They arrived on time and within 3 days changed all my windows and doors. Extremely happy with the product and service provided and would highly recommend to others! Thanks guys! I enclose some before and after pictures. We went from white windows to anthracite grey.Posted on Google Jane AdamsTrustindex verifies that the original source of the review is Google. Very happy with the window and the communication. The fitter was very efficient and cleaned up afterwards.Posted on Google Laura ConnorTrustindex verifies that the original source of the review is Google. What a great company ! Saved over 600 pounds from other quotes, outstanding windows and great fitters that went the extra mile. The guy that owns it is really nice, not pushy at all.
It depends on the style, size and number of windows. A single casement costs far less than a full-house refit with bay windows. Get in touch for a free survey and we’ll give you an honest, itemised quote rather than a vague ballpark figure.
A like-for-like replacement of a single window can often be done in a day. A whole house usually takes a few days, depending on how many windows you’re having fitted and whether any work is needed around the openings.
We supply casement, sash, tilt & turn, bay & bow and flush sash windows, in a range of colours and finishes, including woodgrain effects for period homes. If you’re not sure what suits your house, we’ll talk it through at your survey.
Often they can be repaired. Misted glass, worn seals, faulty handles and sticking sashes are all common fixes. If the frames themselves are badly warped, cracked or discoloured, replacement may make more sense. We’ll inspect them and tell you honestly.
Yes. Every installation comes with a guarantee covering both the product and our workmanship, so if something isn’t right, you’re covered.
Yes. uPVC frames with double or triple glazing cut outside noise noticeably compared with older single-glazed windows. Triple glazing is worth considering on busy roads.
