Environmentally Friendly

Aluminium is one of the most environmentally friendly construction materials on the market, as it’s highly abundant, incredibly durable and infinitely recyclable. In fact, more than 75% of the aluminium produced over the last 100 years is still in use today!

Highly Secure

We use tough, durable and robust construction materials including aluminium and double glazing to ensure that your new aluminium casement windows are incredible resilient. We also implement internal beading and multi point locking mechanisms to ensure the highest levels of security we can provide.

Traditional Framing Options

Our aluminium casement windows can be manufactured with ultra slim sightlines to maximise the amount of double glazing, and the broadness of the views you have from your Belfast or Northern Ireland home. With a wide range of styles available, our aluminium casement windows can suit any home!

Strong and Durable Aluminium Casement Windows

Despite being very lightweight, aluminium is comparable in strength to steel, making it an ideal choice for any installation. You’ll find your new aluminium casement windows can stand up to just about anything and will keep doing so for many, many years to come!

Our aluminium windows are also completely weatherproof, so you’ll never need to worry no matter how wet and windy the Belfast or Northern Ireland weather gets! And aluminium is naturally resistant to all the problems that can come with traditional timber, such as bowing, bending, warping, rotting and discolouring, so you can be completely confident that they’re going to stand the test of time!

Our Happy Customers

Take a look at some of our testimonials from previous customers to see how we have helped transform homes across Northern Ireland.

Honestly cannot recommend this company enough. Had new windows and doors fitted, service throughout was amazing!!! If I could give 10 stars, I would. From customer service, design, quality (which by the way fitted my property perfectly, and I could not have done it alone), communication throughout and finally, installation, which was clean and immaculate with very little disruption. I will definitely go back for future projects. Great value for money too.

The job was done by Total Home NI this week. Two windows have been changed. The guys did a great great job. Showed up in time and also cleaned the area before they left. I can only recommend this company. Big thumbs up from us. Thank you.

Excellent service, staff and great value when compared with other companies we spoke to. Their installation team were fast and very tidy. Covid did mean we had to wait a bit longer for our installation, but that was to be expected. Can't rate this company high enough.

Highly Recommend Total Home; the whole process from ordering to installation was brilliant. The two fitters, Dom and Sam, provided an excellent service and left no mess behind. They ensured I was happy with both my new doors and made sure all locks were working before they left. Will definitely be recommending to anyone looking for new windows or doors!!!
