This was through an insurance claim so I can’t make comment on some sections as I dealt with insurers and not conservatory company . They came back to deal with a leak , again via insurers and not direct . Conservatory design is lovely

From our initial contact to discuss our project and help with achieving our vision of the overall look that we wanted to achieve, the following detailed measure and survey and the fitting team who resolved any unforseen issues whilst keeping everything organised and tidy, then it’s a YES from us and we would recommend D&M

We had three flush casement windows fitted by DM Window Installations Ltd and are delighted with the result. They were punctual, professional, and solved fitment challenges with ease. The installation was tidy, efficient, and followed up with great aftercare. Highly recommended for good quality window installation in the Bristol area.

20th October 2025

Long long delay between order and finished job due to black colour choice being difficult for manufacture apparently. First window manufactured rejected as substandard.

20th October 2025

DM Windows were brilliant throughout the process, from early communication and visits through to the actual job itself.

17th October 2025

Incredibly happy with all the work completed, everything has been done to the highest standard.

Yes 100%

5th September 2025

very good work – excellent product

28th August 2025

A helpful contractor who went the extra mile to ensure a standard of finish we required.

22nd August 2025

There was an error in manufacture by one of their suppliers which was not picked up but once identified they responded very well to rectifying the problem and subsequently were very flexible in terms of timings for latter phases of the project.  All in all I would have no hesitation in recommending DM Windows.

22nd August 2025

Good quality product and customer service

28th July 2025

very efficient

6th June 2025

Great service and post installation help from Chris.

13th March 2025

On fitting the rear door. The fitters ripped up the current floorboard, damaging it and rendering it useless. Instead of getting the carpenter on site to remove it properly.

28th February 2025

It took three attempts to install one window as it wasn’t according to the contract. Fitters were nice but administration and checking the product was fit for purpose before delivering to the customer was below zero. I could see that the window wasn’t correct as they took it off the van but they couldn’t. Yet each time I was assured that the window had been checked before delivering it. Clearly that wasn’t true. Left me with the existing window removed on a freezing day for many hours. Billing is produced late in the day on the day of payment because ‘that’s how their system works’. That’s unfair to the consumer.

25th January 2025

Brilliant, a great experience all round.  Can’t fault them.  Would highly recommend.

22nd January 2025

17th July 2024

Very helpful and very good communications. Arrived as agreed and left the site smart and tidy. Changed things quickly when required.

29th June 2024

Dealing with this company has been great. A difficult project due to dividing the building work into two halves, (to enable us to stay living in the house) which meant two seperate deliveries, and installations. They accommodated these requirements really well. Difficult weather meant a lot of the work was carried out in appalling conditions. Overall, I am really pleased with this company.

2nd December 2023

The contractor sought to rectify any problems we had with the installation and we are pleased with the final installation

24th October 2023

Good follow up and fitted very well in no time at all.

24th October 2023

Very good.

19th July 2023

The Contractor was efficient, the workman worked well and were polite and tidy. I have no complaints about the standard of workmanship. I would certainly recommend the company to friends and family.

30th November 2022

Very Helpful company

24th November 2022

Excellent customer service, easy to contact and dealt with any issues that arose professionally and promptly

24th November 2022

The quality of the doors is poor and poor silicone finishing

24th March 2022

Problem with fitting of window!

16th February 2022

My new windows look great!

16th October 2021

Good job for a competitive price, installed earlier than original target. Thanks, DM.

16th October 2021

Great Service

16th October 2021

Whilst generally happy with outcome of the installation. I would say there were delays and difficulties sticking to the agreed installation date. Communications could have been better as a customer I felt I had to do the chasing to find out what was happening.
