Professional, high quality and thorough service.

From start to finish, our front door replacement was executed seamlessly.
Fitter was polite and courteous with an excellent attention to detail.
Our door is perfectly fitted, handed over with a full aftercare guidance including set up of the supplied smartlock.
Highly recommended company that we will no doubt use again for our other doors.

Thank you.

Contacted them via phone to request a quote. Was told by the lady who answered that I would get a rough estimate in a few days. Nothing was sent, so left a voicemail and also sent a message through their website contact form, yet nobody bothered to get back to me and was ultimately ignored.

Excellent fitters and really polite nd considerate too

Friendly, professional business from first visit to their showroom to last phone conversation checking all was well. Prompt with giving a quote. No messing about with the pricing, the work was carried out well. Happy to accommodate the date i wanted the work done. Immaculately tidy. And now I have a lovely new front door. 🙂
Highly recommended.

Very efficient, communication and timescale all top notch. The assessment beforehand was spot on, the fitter was prompt and easy to work with, did a great job and left no mess. What more could I ask for!

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.

Excellent communication, all visits were on time. Instalation day the team was on time and worked very efficiently despite a bitterly cold day, all was completed (4 windows in one day) and the finish/quality of Instalation was excellent.
All cleaned up and explained the functioning of the windows (locks/ventilation etc)
Entirely satisfied would definitely recommend DS Windows.

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!
S B.
Recently had the front windows and door replaced. From start to finish the service was spot on. Communication was great, did what they said when promised and the entire process or enquiry, measurement, choice and fitting was seamless. Matt the fitter was great, punctual and has helped transform the house. Would not hesitate to recommend their services and will certainly use again if needed.

So nice to have some old school style customer service from start to finish. From getting a quote to lots of emails back and forth the service was 10/10.
Regular updates and options given making the whole experience so easy and professional.

Come installation day, emails few days before highlighting the order of the day. Matt arrived on time and is such a lovely and hard working individual. Regular check ins from Matt throughout the day to make sure I was happy.

Once All complete, all cleaned down, rubbish taken away and porch brushed down followed by an explanation about the locks, key box the cleaning of the door. Even down to a little pot of touch up paint should I incur any scratches over time.

Finished job so good it makes the windows look tired so already booked in for a quote to replace 😂.

I would highly recommend DS Windows and Doors, they are a small local business, very competitive on price but customer service is first class.
Thank you all.

An excellent experience from the outset, no hard sell, Darren listened to what we wanted and gave excellent informed advice….we trusted him. Nothing was too much trouble with advice and support through the design process and the price was and is the best value when compared with other local and national companies, the latter being over 100 percent dearer and inferior products. The fitters (Matt and Rob) arrived on time every day and over the three days proved to be efficient, helpful, tidy and problem solvers….they worked really hard and took pride in their work. DS windows charge 50 percent on contract and the remainder once the work was completed and we confirmed it was to an agreed standard ( this is not the approach for many companies). So no hard sell, quality windows that met our needs, expertly fitted, no mess and really competitive pricing…..thankyou

Further windows fitted in Feb 2025. Good price and excellent work by Matt and Rob who really take pride in their work and go out of their way to ensure everything is done to a high standard…..keep feeding them tea is the trick
Response from the owner:Hi Paul, many thanks for taking the time to leave us a review. We're delighted you were happy with everything.

A good experience with this company. I had a new window put into my kitchen wall for more light. The price seemed very fair. The guys that came we very nice and, professional. Left everywhere nice and tidy and did a good job. Very happy and would definitely use again.
Caroline Q.
Had a composite door fitted. The fitter was lovely and very good at his job the door looks wonderful. No draughts and the door lets in plenty of light unlike our old one. The locking mechanism looks to be extremely safe and secure. The whole process of buying said door was easy, from the rep who first came, to fitting the door. Everyone at DS was friendly and professional and kept me informed of every step. All in all very pleased

We are very happy indeed with DS windows and doors. From initial enquiries; to measuring up; to fitting all of the windows we can not fault anything. Matt and Rob (the fitters) did an excellent job, in a friendly, but professional manner. They fitted the windows so neatly and cleaned up thoroughly.
We would highly recommend DS windows and doors
Response from the owner:Hi Jo, thanks so much for your kind words – reviews really help us as a small, family-run business. Many thanks for choosing DS Windows & Doors.

Fantastic service from Rob.S - very professional and got the job done quickly and efficiently! Would highly recommend 👍🏼
Ryan W.
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!
