Good product very neat and hassle free fitting had two new windows upstairs bedroom and bay window in front room all done in one day very neat and tidy job would definitely recommend
Andrew T.
Excellent job professionally executed. The job was a simple replacement of some blown double glazing units but from the initial measuring to final fitting, the service from DS Windows & Doors was exceptional. No hard sell from the sales rep, and the fitter, Rob was excellent, friendly and very professional. I would not hesitate to recommend DS Windows & Doors and they will be my first call for any future window or door needs.
Lyndsey W.
Brilliant service and great job thank you
Annaliese H.
Phenomenal service throughout. Jim was very informative about our options and was very helpful. Rob came and put our new front door in and did an excellent job. He was friendly and polite. We are extremely happy and would highly recommend. Will definitely use again in the future!

A very professional company from contact to fitting.
A few queries before fitting were cleared up...thanks Donna. Then on fitting day Rob and and Matt were very professional and courteous. Their work was very tidy and all cleaned up at the end. I would happily recommend this company and use them again.

Had a new composite front door installed today by Matt. Matt was very friendly and polite, cleaned up after himself and made sure i was happy before he left. The customer experience from beginning to end has been great. No pushy sales team just years of experience on the job and all questioned answered and explained. You can tell this is a family run business and not a nationwide company that do a job and leave, they are people at the end of the day and interact like people. Its been a pleasure doing business with the team. Thanks everyone!

Great communication, great installation team and the price was good!

An overwhelmingly positive experience. Replaced my door with a better quality composite one. Effortless (from my point of view), quick, accurate measurements and quote, installed it in one morning and it looks fantastic (not to mention being much more secure). The installers were friendly and polite, did a high quality job and cleaned up after themselves- couldn’t ask for more.

From the moment I made the enquiry to the day I had my new composite door installed, DS Doors were nothing but brilliant. The back office team along with Darren and Matt who fitted my front door were amazing and made sure there was no mess after installation. The door looks amazing and I’m sure and know that others will follow suit in replacing there existing front doors to these new amazing looking front doors. Thank you DS Doors for making our home look even better than before👍🥇

Wow, where do I begin with this company from my first enquiry to my final fitting yesterday? It has been AMAZING the quote given to me was fair and honest also had no pushy sales technique which made me really want to use this company from the get go! Darren came to survey my home at the time agreed really nice friendly guy. I even had some questions about a window upstairs Unrelated to my enquiry and he happily had a look for me and gave me some advice. I was kept up to date whilst my order was processed. Yesterday I had the pleasure of meeting Matt who fitted my French doors for me with care and professionalism He was super friendly and down to earth. Matt took time ensuring that everything was just right keeping me updated along the way. He cleaned up and also advised me on care going forward. I’m so happy with the end result I’ve actually already told a friend about this company. All I can say is I wish I had a found DS Window And Doors for my previous work don’t hesitate in using this company The quality of the door is top notch no damage to my wall at all when removing the old ones these guys really do care about what they do and their customers. The people I dealt with in person and via telephone/emails were amazing and so lovely that goes such a long way thank you all so much for everything! I wish you all the best going forward with your business ⭐️⭐️⭐️⭐️ ⭐️ +
