We're so pleased with our new windows from DS Windows and Doors. The windows themselves are gorgeous and finished to a really high standard, and the professional installation by Matt and Rob was far smoother than anticipated - efficient, tidy and painless. On top of this, the customer service was fantastic - Donna was so organised, helpful and attentive, making the whole process effortless from start to finish. We’d recommend DS Windows and Doors to anyone and would definitely return to them in the future 😊

Absolutely can’t fault this company. Extremely helpful and accommodating. 8 weeks from first enquiring to fitting. Darren, Donna and Mark were second to none in their customer care and attention to detail. Will definitely use again.

Thank you to DS windows and doors. We had all of our windows done and 2 doors and french doors.

We saw Darren in the showroom who helped us with our so many questions as we had never bought windows and doors before.

Donna in the office also so helpful and happy to answer many questions! They were able to fit installation around our schedule.

Matt and Rob the fitters were just so friendly and efficient - they were really tidy and took real care when working. They also answered any questions we had during the process. The windows and doors look amazing and they were installed so quickly!

Perfect! The team at DS Windows were friendly, knowledgeable and efficient from start to finish (and patient). Our renovation has gone a lot more smoothly dealing with this company. They understood what my wife and I wanted and fitted around our plans and we are so pleased with the result. Highly recommend 👌

DS Windows and Doors exceeded all expectations. I spent quite a while searching for a company I felt I could trust. Their other reviews were really good so I decided to give them a call. I spoke to a lovely lady called Donna, she answered all my questions and was so bubbly and set my mind at ease to give them a try. Darren came to give a quote. He was very helpful and had lots of good suggestions for windows we may not of thought of. We found the cost resonable and went ahead with the order.
I was apprehensive, expecting there to be quite a bit of mess, but need not of worried. Two lovely guys Matt and Rob came to do the installation and they were brilliant. Their work was so neat and tidy, no mess apart from a bit of dust. Could not of asked for nicer people, or a better job. Really thrilled with everything. I totally recommend this company.
Response from the owner:Thank you so much for your lovely review! We’re really pleased you chose us and that Donna, Darren, Matt and Rob all looked after you so well. It’s great to hear you were happy with the advice, the installation, and how tidy everything was left. We really appreciate your recommendation – thanks again for trusting DS Windows & Doors!

This is a great firm to deal with. Communication throughout was excellent, the price was very fair and the fitting of the front door was carried out efficiently and skilfully by Matt who was also a really nice bloke as well! Highly recommended
Response from the owner:Thank you for your fantastic review! We’re really pleased to hear you found the whole process smooth and that you were happy with the communication and pricing. Matt will be delighted to hear your kind words – we’re glad you’re happy with your new front door and the quality of the installation. Thanks again for your recommendation, it’s greatly appreciated!

DS Doors and Windows came recommended to us, I cannot say how highly I would recommend this company to anyone looking to replace their existing doors and windows. From beginning to end, the communication, the guys that fitted our doors, all were absolutely amazing, we are thrilled with our new doors, they are all friendly, professional, clean up after themselves and did a fantastic job. It’s difficult these days for some company’s to deliver on what they promise but they did that and more. Thank you to all of you for everything, you are all a credit to the company
