Endeavour Windows & Home Improvements are widely praised for their high-quality replacement windows, composite doors, and bifold installations, leaving homes noticeably transformed and warmer. Clients frequently highlight friendly guidance from Josh and Jack, competitive pricing, and polite fitting teams who work efficiently and leave properties tidy. However, several customers experienced notable frustration with head office communication, reporting long delays, missing finishing trims, and poor follow-through when resolving snagging issues.

We had new conservatory windows, a bifold door in conservatory and a new back door fitted with Endeavour. We wanted to use a local company and Endeavour are on our doorstep at Marton Shops so they seemed perfect. Once our initial deposit was paid and finance plan set up communication was non existent unless we chased Endeavour up. Unfortunately there was one mistake after another leading to lengthly delays and getting any information or reassurance from the office and management team was next to impossible. The office staff didn't seem to know what was going on and they were very unhelpful and seemed to just want to get us off the phone asap. We were kept completely in the dark about what was going on and when fitting was going to happen. The fitters were nice hardworking lads, but there was one occasion when they did not have the correct equipment for the job and another occasion where the fitters failed to turn up on the agreed time and day and we once again had to contact Endeavour to try to get some information. Throughout the whole process we were constantly chasing Endeavour up. Very very stressful indeed. Overall this company comes across as very unprofessional. We had our new back door fitted by Endeavour early June 2026. The fitter came without some trim for the door. We are still waiting for our back door trim to be fitted. We have phoned up numerous times asking when will it be fitted and we get ignored. We have given up contacting Endeavour about the trim now and we are going to buy it elsewhere and fit it ourselves. Which is not really on considering what we are paying for the work. Don't expect anybody to contact you once work is completed to see if you are happy as after sales care is non existent with this company. We are happy with the end result and our conservatory has been transformed by the lovely new windows and doors fitted by Endeavour, but the whole process was very stressful and frustrating with constant delays. We can accept that mistakes happen but we can not accept poor management and non existent customer service skills. I don't think we will be using Endeavour Windows again unfortunatley.

Absolutely delighted with my gorgeous windows. They have elevated the appearance of my home exactly as I had hoped they would. Though my house is hidden away I have had compliments from my neighbours. I had not intended on having my porch windows replaced initially as they didn’t need it. Jack rightly said that perhaps I should consider including them as it would make a huge difference - guess what? He was right! It’s as though he knows his trade! The fitters were great, really good workers. My only slight hiccups were lack of contact between the order and fitting and some minuscule finishing touches taking time to get done. This was down to suppliers. It was all sorted without issue. Would I use them again? Yes. Do I recommend them ? Yes.

Excellent experience from start to finish. Installation brilliant and very professional. Tradespeople very professional, skilled, hardworking, turned up on time and respected our house. Price was very fair for a whole house and doors. Windows and doors super quality. All in all very good indeed and fully fitted within the timescale we were told. Highly recommended.

I highly recommend Endeavour Windows for window installations. I recently had windows fitted by them and all staff were polite and respectful. Thank you for the great and efficient service!

I wouldn't let them fit a letterbox. They left our roofline in such a mess we had birds nesting in it. They ignored our emails for months & when we did eventually get them to do the remedial work that wasn't without its issues. Please remove my details from your mailing lists.
