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.

When an issue arose they resolved the matter quickly and to a high standard.Posted on Google Zayd WilsonTrustindex verifies that the original source of the review is Google. I had several quotes from the large national companies and local companies. From the outset Adeel from Glitz made me feel comfortable, no pressure selling like some of the others, no over quoting or recommending extra equipment that wasn't needed, just a fair and honest assessment. Once I received the quote Adeel was very attentive, giving us his time to make some final design choices which was really helpful as we were new to this. Throughout the process Adeel kept us informed and made us feel comfortable. The work was carried out well and the installers were great. Would recommend highlyPosted on Google Lilka JayTrustindex verifies that the original source of the review is Google. Adeel and his team built a porch for me last week and I couldn’t be happier with the results. He had helpful advice about the design and kept me informed during the process. I can definitely recommend his company. Eliska HoarePosted on Google Valeria STrustindex verifies that the original source of the review is Google. We recently had our French door replaced by Adeel and his team (Ali & Jib), and we couldn’t be happier! The door is of outstanding quality, beautifully made, and everyone who visits compliments it. Adeel has been incredibly kind from the start, accommodating every request with clear, easy communication. On delivery day, he even called to see if I was nearby so they could place it inside- such a thoughtful touch! The team was friendly, efficient, and professional. We’ll definitely call them again. Highly recommended!Posted on Google Gursharon BirdTrustindex verifies that the original source of the review is Google.

Would recommended for anyone looking for new windows!Posted on Google Jay SmithTrustindex verifies that the original source of the review is Google. High quality customer service and quality of workmanship. Would highly recommend. Was a pleasure to work with this company.Posted on Google Gioia CattiniTrustindex verifies that the original source of the review is Google. Working with Adeel was great. He is a very good communicator, he listened to our requests carefully and gave us good suggestions on how to design the windows for a great looking result. The new windows are exactly how we wanted them to be and very good quality as well. The job was executed quickly but with attention to details. We had an issue with one of the window's handle but Adeel took charge of replacing it fast. We will definitely contact Adeel again gor future works.
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.
