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.

Total Home NI team were great to work with start to finish, they kept in touch to make sure that the work agreed at original sales matched survey and then order before being sent to factory. Like all jobs there are little things that fall out of bed when at construction stage but these were all sorted on the day and had no impact on me or the finished product. The Install Leader, Marcin, has been in touch since to make sure everything was still up to scratch. Marcin and his team a credit to the company and very happy with the product so far!

Knowledgeable and helpful during selection and specification. Provided regular updates during manufacture. Flexible with dates for installation. Installers were quick, tidy and very efficient. Payment process was easy to use.

Absolutely delighted with my full house transformation. 2 beautiful uPVC doors front and back and 13 windows in total. The fitting team were FANTASTIC, and even with a few surprises behind the walls along the way they managed everything so professionally and did a superb job in the tidy up. Nothing was a hassle to them! Thanks also to Damien and Louise for a seamless experience start to finish which was just under 8 weeks, and finally Marcin for the last finishing touch! My house now feels like the perfect 'warm ' home just in time for the cold. Love it!

Just had patio windows and a door installed, the 2 guys that fitted them were super efficient, quick and very pleasant. They really impressed me, because they even cleaned up all their mess! My house was all clean and sorted straight away! I have never had such amazing service! Thank you to the fitters! You done a fab job... Oh and the new windows look great 👍 10/10 from me 👏👏👏

I have purchased 2 front doors from Total Home NI and both times it’s been very professional. Front doors have been well fitted and work men installing friendly and work clean and tidy. Lots of payment plans to suit your needs. Would highly recommend this company.

Got some doors and windows installed with Total Home NI. Everything from ordering to the installation went nice and smooth. I was a bit worried about the freshly renovated bathroom but the guys are no doubt very professional and highly qualified in this matter. I was chuffed when arriving home and discovered that everything was installed perfectly, and all rubbish cleared. Afterwards we've asked Marcin to order us a clear glass at the front door instead of obscure and to fix two issues ( fine tuning really at the front door) and he could not be more helpful. They've sorted all my issues without charging me a penny extra. Everything looks nice and high end quality and I highly recommend this company as they're brilliant. Will see how the windows and doors are behaving in time and I'll come back with a review about endurance and reliability of these. At the moment all 100%. If more companies would work like these boys, life would be much easier.

Very professional service from start to finish. Survey and quotation was quick and the installation was efficient. We had new windows and a composite door fitted in two days.

Excellent service and communication from design start of my new front door which finalised every detail to a very smooth installation on the day. As a construction professional myself I would have no hesitation recommending Total Home NI

I visited showroom and was allowed around on my own with no one standing or hovering over me. Any assistance I required was given promptly and effectively. I subsequently made my decision and received a contract. Doors were fitted as required and workmen were clean tidy and efficient. Representative contacted me after installation to check that all was good. Very efficient company that I would recommend and use again.

Great job on the fitting, didn’t waste any time, fitted over 2 months ago and haven’t had to get anyone back for any fixes, no gaps or problems, very thorough and well done job and very competitive price.

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!!!
