uPVC Casement Windows in Norwich, Norfolk and Suffolk

Q: How long does it take to fit uPVC casement windows?

Most homes have their windows fitted within one to two days, depending on how many windows are being replaced and how easy they are to access. During your free survey, we will confirm exactly how many windows are involved and give you a realistic timescale, so you know what to expect before any work begins.

Q: Will you need access inside my home?

Yes, our fitters will need brief access to each room where a window is being replaced. We plan the day carefully to work efficiently and minimise disruption, protecting your floors and furnishings as we go, and we will always leave your home as we found it once the job is complete.

Q: Are you registered with FENSA?

Yes, we are a FENSA registered installer. This means every installation is carried out in line with current building regulations, and you will receive a FENSA certificate once the work is finished, which you can pass on to a future buyer when you sell your home.

Quality and Performance

Every window uses an engineered, multi-chambered uPVC profile, achieving U-values as low as 0.9 W/(m²K) and a Window Energy Rating of up to A+25. The multi-point locking hardware carries its own 10-year mechanical guarantee, and the hinge protection is tested to twice the force required for national security accreditation, so security is built in rather than added on.

 Trustindex verifies that the original source of the review is Google. Absolutely fantastic service from start to finish. The team was professional, friendly, and incredibly knowledgeable throughout the whole process. The windows look amazing and have completely transformed the appearance of our home. Installation was quick, tidy, and completed to a very high standard. Communication was excellent, and everything was finished on time with no hidden costs. You can really tell they take pride in their work. I would highly recommend this company to anyone looking for quality windows and reliable service.

 Trustindex verifies that the original source of the review is Google. Windows Plus just installed a new front and back door for us.  We are really pleased with the quality of the work and really good service throughout.  We will use them again and recommend them to others.

 Trustindex verifies that the original source of the review is Google. So it’s been a few months since Windows Plus were here but I wanted to see if having 2 new doors and a couple of windows would actually make any difference to the river of condensation I’ve been coping with the previous two winters in my bungalow! Oh My goodness, Yes it certainly did!! This is the first winter I’ve been condensation free and it’s been absolutely fantastic, even feeling a bit warmer! David and Wayne were so professional and great craftsmen. The finishes were great and they dealt with any little niggles along the way with ease, even fixing my door bell (which by the way is still working great guys lol)! I couldn’t be happier with the price and service provided! I would definitely recommend Windows Plus! Many Thanks!

 Trustindex verifies that the original source of the review is Google. I have used Windows Plus a few times and have had nothing but excellent service every time. Adrian prices competitively with no pressure sales. The service Lee provided when fitting the door was second to none. Nothing was too much trouble and when left you would never know he had been. Great job thanks guys.

 Trustindex verifies that the original source of the review is Google. 5 stars I had been told I needed to replace my window by multiple companies and quoted over £1k for replacement. Spoke to Windows Plus and they sent out an engineer and repaired the window within a week. Super happy with the service and the finish - thank you so much!

 Trustindex verifies that the original source of the review is Google. A Glowing review from a warm happy customer. Windows Plus fitted a new door and front windows in my flat for a reasonable price. They have already fitted a new back door and windows. Excellent service from them and I'm very happy.

Frequently Asked Questions

How long does it take to fit uPVC casement windows?

Do I need planning permission for replacement windows?

Most like-for-like window replacements do not require planning permission, as they fall under permitted development rights. This can vary if your property is listed or sits within a conservation area, where additional consent may be needed. We recommend checking with your local authority if you are unsure, and we are happy to point you in the right direction based on our experience across Norfolk and Suffolk.

Will you need access inside my home?

Are you registered with FENSA?

What is the difference between casement, flush casement, and French casement windows?

A standard casement window opens outward on a side hinge. A flush casement window uses the same opening style, but the sash sits flush within the frame for a more traditional, timber-look finish. A French casement window has two sashes that open outward from the centre with no central post, giving an unobstructed view. We fit all three, so we can help you choose the best fit for your home.
