 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 are aluminium casement windows different from uPVC casement windows?

Aluminium allows for a slimmer frame profile for the same opening size, giving a more contemporary look and letting in more natural light, while still offering excellent strength and weather resistance. This makes aluminium casement windows a popular choice for homeowners across Norwich and Norfolk who want to maximise views and light without compromising on performance, while uPVC remains a cost-effective option for those prioritising insulation and value.

Are aluminium casement windows suitable for period properties?

Yes, with the right colour and profile choice, they can suit both contemporary and more traditional homes, and precision installation ensures a seamless fit either way. Many homeowners choose slimmer sightlines or heritage-style profiles to complement period brickwork, while our experienced team ensures every window is fitted to the exact specifications of your property.

Are my casement windows thermally efficient?

They offer excellent thermal insulation, helping maintain comfortable temperatures year-round and reduce energy costs. This is achieved through advanced thermal break technology within the frame, which limits heat transfer between the inside and outside of your home, making aluminium casement windows a practical, energy-efficient choice for homeowners across Norfolk.

Do aluminium casement windows need much maintenance?

They are low maintenance and do not need painting or varnishing, typically requiring only an occasional wipe down to stay looking their best. The frames are also resistant to corrosion, warping, and fading, so they retain their appearance and performance for years, offering homeowners across Norfolk a practical, hassle-free choice.

What colour options are available?

You can choose from over 150 RAL colours, including dual-colour finishes with a different shade inside and out, giving you real flexibility over the finished look. This wide selection allows homeowners across Norfolk to match their new windows precisely to their property’s brickwork, render, or design scheme, whether they prefer a classic or contemporary style.
