Dave and Mattie worked solidly to complete the job in one day, even though it meant they worked later than planned on a Friday afternoon. They were friendly and respectful of my property. The carpets were cleaner after they left than before they arrived! Dave advised on a colour match for masonry paint, which was unexpected and appreciated. Top tip: they can drink impressive amounts of coffee so be ready to keep them supplied with hot brews!

From my first enquiry, the response from Fortis was prompt and professional. (Another local firm never even returned my call!). John visited to give me a quote a few days after I called them. Everything was clear and I confirmed my order soon after. I was happy with the price and I’m delighted with my new front door and windows. Highly recommended!

Exemplary service from Fortis, we had a Rockdoor supplied and fitted. Graham did a great job fitting the door. The quality of the door is excellent and the door looks great.
Highly recommend. Thank you!

Just had a rock door and sash style windows installed. The service from these guys is exemplary. Starting with John with the estimate (even returning when we decided to have windows) all fitted on the original fitting date, to the fitting guys who were respectful, tidy and had excellent attention to detail. I cannot recommend the guys at Fortis highly enough

John and his team came to the house within a week of requesting a quote for the works. Their engineer was very knowledgable and recomended work that needed doing and why, but also advised work that did not need doing, just minor adjustments, which saved us money. We were so impressed with the efficiency of Fortis windows, that we decided to take up their promotion for two new doors (Front & Rear Fitted) at the reduced rate offered. Fortis windows are very competitvely priced, and in our opinion, offer excellent value for money with very friendly, knowledgable & efficient team of engineers & fitters. We definately recommend this company.

A huge thank you to Fortis Windows for fixing a couple of our windows. I was surprised at how quickly they fixed the problem and I was really impressed that the place was left neat and tidy. I will definitely use them again and have already recommended them to my mother and father in law. Excellent service!

I approached this company to replace a badly scratched glass window that I needed changing.After spending about half a hr at my property and confirming the window was faulty and indeed need changing all good and he left.Angry and annoyed that less than 24hrs later he says he can’t change it with a feeble reason that it’s too near another window company radiance doors who fit the dodgy window.What????? You waste a customers time and come back with that pathetic reason.Shocking way to treat someone it’s not our fault radiance doors ripped us off £6k Thanxs for blaming us for faulty glass not what you said when you was slagging their company off was it😡🤔

Fortis Windows had the shortest lead time from John consulting with us to fitting our front door, far quicker than any competitors delivery estimate and we are immensly grateful for this. The team who fitted the door and side light were extremely efficient, friendly and left the area in a spotless condition. The Newark Rockdoor looks brilliant and we have had very complimentary comments from visitors. We love it and will use Fortis Windows for any future requirements and highly recommend them. Many thanks to you all.

Fortis have just completed work replacing 8 windows and our back door. The service has been exemplary. Clear communication throughout, a competitive quote and all timelines met. Our house is old and no walls are straight so it was not an easy job and yet the fitters remained professional and cheerful throughout. We have had a lot of work done on our house over the years and I can honestly say I have never been as pleased with both the way a job was carried out and the end product. The attention to detail was fantastic and they clean up REALLY well - I think the house was cleaner when they left than when they arrived!! If you are looking for someone to fit windows or doors look no further I don't think you could find a better service.

Amazing service. Kept updated via phone or email from day 1 of measuring to the day of fitting. The lads/men were great, very efficient. No mess/very tidy (cleaned up after each window was fitted), on time and polite. Would highly recommend.

My day-to-day job is working with contractors, so I feel that I’m in a good position to give honest feedback regarding the quality of work and client interaction received by Fortis.
Recently we were quoted for an outhouse UPVC door and window replacement. Fortis were very prompt in agonising a visit from my email enquiry. They arrived when they said they would and were very professional. John offered good advice and options, and I had a written quotation back within 3 days.
Fortis were very competitive on price, so we agreed to proceed.
Leadtime was 4 weeks, and to the letter I received a call a week in advance to make arrangement for fitting.
The work was carried out in a highly professional way. Attention to detail was great and the work area at the end of the day was cleaned without a trace of rubbish. I was extremely pleased with the work carried out.
As a side note and demonstration of the commitment to customer satisfaction. I spoke to John about a previous installation I had done only a few years previous that had started to develop defects. The installer I’d used had gone bust and I’d exhausted avenues to claim from the manufacture . John said he had contacts with the manufacture and that he could enquire to see if anything could be done. I didn’t hold any expectation being my experience.
To my amazement John came back to me that the manufacture as a sign of good will would replace the faulty equipment. Something I’d given up on. I was extremely grateful to Fortis for going above and beyond.

John and Shaun completed my windows and door installation on my self build dwarf wall installation. Fortunately that passed inspection!! Their on site performance was excellent and the tips given to me on how to complete the roof proved to be of great assistance. All round they were fantastic and would not hesitate to recommend them to anyone. Thanks once again Pat and Mandy.PS the roof has gone on!!

Thank you Fortis Windows for an excellent service and installation of my new front door set.

It would be remiss of me if I didn’t mention your fitter Graham, who undertook the installation. We found Graham to be a consummate professional and this was clearly evident in his approach and quality of installation. He is a credit to your business and I am sure epitomises your values and care for your customers. As a qualified joiner myself and now managing multiple tradespersons on large project, I am not easily pleased but experiencing Graham’s application and professional service I could not find fault in anything- A perfect service.

My experience with Fortis Windows Limited was excellent and would not hesitate to recommend you.

Kind Regards

Fortis have just completed replacing our windows, patio door and front door. I could not give these guys a high enough review. The price was competitive, communication was excellent and the team who came out to do the fitting (Dave and Graham) were really good. The work was completed to a very high standard, and was spotlessly clean. There was a small delay in fitting 2 glass panels due to the current supply situation, but i was kept informed, and everything was sorted quickly. I would highly recommend Fortis to anybody.
