An excellent service from start to finish

An excellent service from start to finish and couldn't be happier with the results.

With it being an old house there are usually issues when work is done but anything uncovered was dealt with without fuss. Could not recommend them more highly.
Anyone I met through the process at Williams Windows & Doors was incredibly friendly and extremely competent.

No request was too much :)

New Front Doors

From the initial visit to our home to discuss the our requirements to the final installation Williams Windows were professional and helpful. The doors are excellent quality and the fitters were quick and tidy and left a very sharp job.

We had been looking for a new front door for over a year. All the companies we contacted never pitched up as promised. We saw Williams Windows van out one day and spoke to one of the guys who gave us his flyer. Contacted Frasier who came out within a few days and advised us very professional. The guys who installed our door were first class 👌 Definitely recommend this company👋

Customer Service

Ordered door and one window in October. Finally heard from company in January to say they would arrange installation date. Fitters arrived minus door! Discussed window with fitters to discover I couldn’t clean outside of window from inside house. Asked them to not bother fitting it. Also wanted to know when door would be ready. I had to keep phoning for updates. Customer service leaves a lot to be desired. Eventually fitters returned with door and window, fitted door but couldn’t actually believe window was not correct fit. Old window was removed and non fitting window put in and made safe with some sort of foam until correct window would be ready. Again I had to phone for updates. Fitter eventually arrived to replace window, wrong handle on it! Handle changed. Not impressed with companies handling of my order. Can’t fault fitters, they were very helpful. Certainly would not recommend this company.

Dear Barbara,

Thank you for sharing your feedback. We take all reviews seriously, and as a business that has thrived on local reputation for 30 years, we are naturally disappointed to receive a 1-star rating.

We would like to clarify a few points regarding your installation to provide a full picture of the project:

The Door: As a bespoke composite door, the lead times are naturally longer than standard units. We are, however, pleased to hear that the final installation met your expectations and that you are delighted with the finished look.

The Window: Our records show the initial window provided was built to the agreed specifications. When the subsequent sizing issue arose during the second visit, we were completely transparent, immediately manufactured a replacement, and ensured the property was made safe and secure in the interim.

Going the Extra Mile: Our team always strives to be helpful, which is why our fitters were happy to install a complementary trim on a pre-existing window (not supplied by us) to resolve a draught issue for you at no extra cost.

Resolution: We acknowledge that there were communication delays, for which we have sincerely apologized. To reflect this, we provided a discount on your final bill as a gesture of goodwill.

We are pleased that the job has been completed to your satisfaction and that you found our fitting team helpful. We wish you the very best with your new installations.

Kind regards,

The Management Team

Brilliant experience from a local company who put customers first

Firstly, I chose this company because of Trustpilot reviews - windows and doors are a huge investment and we wanted to be sure we chose wisely.

The whole process was seamless with excellent customer service. We live in a listed building so we needed drawings before ordering to secure consent - this was no bother and the team went above and beyond to get these to us and there was no hard sell.

We were walked through all the options and advised on the best choices for our home, which have turned out brilliantly as the light is now flooding in (even in winter!) and the views have been opened up.

The installation team were brilliant, worked hard and treated our home with care and respect to minimise disruption for us (home workers) and our pets. And we were pleasantly surprised when Fraser visited mid-way to ensure we were happy with the work and our choices.

Long story short - this company was EXCELLENT value for money, put customer service first and we would not hesitate to recommend them.

Great Product, Great Fitters

I choose this Company because I had worked in the Home Improvement Industry for years, and had done my due diligence and research into their product and Company. The specification is to a high standard, and is made by the Company in Clydebank. The 2 installers were excellent fitters , and managed to overcome a couple of difficult issues at the install. They both worked non stop, ensuring the windows were fitted to a very high standard. And at the end of each they cleaned and hoovered up. I have came across dozens of window fitters over the years and would rate them 10 out of 10. I would recommend Williams Windows to anyone, they have been established for 30 years , they have a waiting list for installation so peace of mind is assured
