Glitz Windows & Doors is a family-run glazing company based in Coulsdon, and we’ve spent over 25 years fitting windows for homeowners across South London and Surrey. Our casement windows aluminium frames are slim, strong and secure, which means more glass, more daylight and a sleek look that lasts for decades.
Every job comes with FENSA-registered fitters, a 10-year guarantee and a free, no-obligation survey. Most standard replacements are finished in a single day, and you deal with one local team from your first call to the final tidy-up.
We’re not a national chain. We’re a local team that understands the homes and weather of Surrey and South London, and our own experienced fitters carry out every installation.
Each window is built to fit your openings exactly. You can choose side-hung, top-hung, fixed or flush casements, in a wide range of colours and finishes.
We visit your home, take accurate measurements and talk through styles, glazing and finishes, with no pressure to buy. You’ll receive a detailed written quote afterwards.
Most standard replacements take a single day. We protect your home, remove the old frames, fit and seal the new windows, then tidy up and check everything with you before we leave.
Our FENSA-registered fitters work to current Building Regulations, including Part L for thermal performance and Part Q for security. You’ll receive a FENSA certificate on completion, which you’ll need when you sell, plus our 10-year guarantee.
Windows rarely fail overnight. They slowly get colder, noisier and harder to use until one day you notice.
Look out for draughts, condensation trapped between the panes, rotting or warped frames, stiff handles and heating bills that keep creeping up. If two or three of these sound familiar, replacement usually pays off.
You'll enjoy a warmer, quieter and more secure home, with far less upkeep. Aluminium frames don't rot, warp or need repainting, and fresh windows do wonders for kerb appeal and resale value.
Aluminium gives the slimmest frames, great strength and a long life with minimal maintenance. Explore our Aluminium windows to see the full range of styles and finishes. uPVC is a popular budget-friendly choice with thicker frames, while timber has a classic look but needs regular painting and care. We fit all three, so we’ll give you an honest recommendation for your home.
Not every problem means a new window. We supply, replace and repair all window types, so we’ll fix what can be fixed.
Worn hinges, stiff handles and tired seals cause most draughts and rattles. New hardware often makes a window feel like new.
Fogging between the panes means the sealed unit has failed. We can usually replace the glass without replacing the frame, and cracked panes can be swapped quickly, with safety glass if needed.
If a frame is badly damaged, or several windows are failing at once, replacing them often makes more sense than paying for repeated repairs. We'll always be upfront about which route suits you.
Every home is different, so there’s no single price that fits every project. The cost depends on the size and number of windows, the type of glazing, your choice of colour and finish, the opening style, and how easy your property is to access.
The simplest way to find out is to ask us. We offer a free survey and a detailed written quote with no obligation. Customers often tell us they appreciated a fair, honest assessment without being sold extras they didn’t need.

Posted on Google Barnaby DawsonTrustindex verifies that the original source of the review is Google. Adeel and his colleagues were very considerate and efficient. 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. I couldn’t be more satisfied and impressed with the quality and fitting of my windows and doors. Adeel and his wonderful team are local and professional in their ability to deliver. I will definitely be using them again for future projects. 5* plus!!!Posted on Google Ellie CarterTrustindex verifies that the original source of the review is Google. From meeting Adeel for a quote to having our new windows installed, the whole process has been smooth and effortless. I was kept in the loop with delivery times and start dates and the guys who installed the windows were extremely polite and worked very quickly. They also tided up after themselves. 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.
