I asked Alex to replace all the windows in my house, a big job. From the start, Alex was professional, thorough and knowledgeable. During the time from placing the order and the arrival of the windows for fitting, Alex kept me informed of the progress at the factory, delivery day and what I should expect once he and his team came on site. His customer service ethic is outstanding. The job was completed on time. On the last day, Alex and Gary tidied up everything and took away the old windows and frames, leaving me with the new windows in a tidy home. I’m delighted with the new fitted windows - they look even better than I expected!

Alex recently installed a new front door and bedroom window. The price was very reasonable compared to other quotes received and lots of options for the door design. Alex was prompt and ensured everything was cleaned up afterwards. I am very pleased with my new door and window and wouldn't hesitate to recommend them to others. Thanks Alex!

Some friends recommended Alex when we moved house and wanted all our windows and front door changed. We got some other quotes anyway but Alex was very reasonably priced. He was very accommodating with all our changes and indecisions too. Communication was very clear and installation dates were actually quick compared to the other suppliers we contacted. Onsite, he and his colleague Garry were super efficient, diligent, tidy and really friendly and lovely. They did a really good job and made good nicely. Couldn't recommend Alex more!

Alex and his team were so fantastic in replacing our windows and doors! They were prompt, polite, incredibly clean and tidy and we are so pleased with the finished work. The patio doors, kitchen stable door and front door are all flawless and the finish and sealing on all the windows and doors is perfect. The amount we paid was the exact quote we were given and there were no hidden costs. Alex and his team are definitely perfectionists! We would highly recommend Alex and his team for any windows, doors or glass replacement.

Alex fitted 2 bay windows, 1 smaller window and new French doors. Excellent service throughout, from initial survey and estimate, fitting them with Alex and Gary, through to rectifying a couple of issues with the glass (a depot problem, not Alex). Professional, courteous and on time throughout. Excellent value for money, when compared to other people who quoted. Would definitely recommend them.

Alex and Gary have been replacing doors and windows for many years and that tells its own story. I received 5 quotes for the work and Alex stood out from the rest. Calm, knowledgeable, punctual, and by no means the most expensive, he always followed up on what he said he would do and didn’t expect me to pay 90% of the final invoice price, before work had even started, unlike many of his competitors. The quality of the doors and windows they fitted, despite mistakes made by the factory, some of which cost Alex, was as he had promised - excellent. The quality of the installation by both him and Gary - faultless. Even the small things - the making good and tidying up was done without fuss and done with care. I wouldn’t hesitate to recommend Alex and Gary. A fine team who deserve every success that comes their way.

We have had all the windows in our house replaced, the work completed in two batches. Both times I have been very impressed with the quality of windows themselves, the professional and very efficient installation and the very competitive quote. They left the house clean and tidy and the finish on the windows is immaculate. I have already recommended them to a family member and they were also very impressed with their windows and doors, and installation as well. I would thoroughly recommend Alex Dobson Windows & Doors.

Alex quoted for fitting a new door - undecutting one other quote we had. He kept us well informed of the delivery times which were disrupted because of the coronavirus, and then arranged a date, arrived on time, fitted the door perfectly, cleared up and left. Perfect.

Replacement of polycarbonate conservatory roof to Activ blue self cleaning glass
Customer Service

Our Monarch aluminium conservatory has had a polycarbonate roof since being built 25 years ago. We decided that an upgrade to glass panels would improve both temperature control and appearance of the roof. Mr Dobson was prompt to reply to enquiries, and of the quotes we received, was the most competitive and he offered sensible advice as it was not really necessary to replace the whole roof! The existing polycarbonate panels were templated on one visit and then the Activ Blue glass panels fitted a few weeks later. The roof has been completely transformed by this glass and now gives a modern airy look to the conservatory. We highly recommend this company.

High quality work done on time and at agreed price
Work involved replacing all windows in old semidetached property and new windows and doors in single storey rear extension. Alex carried out the work at the time he said and within the timescale agreed. The job was done very professionally and highly satisfied with the result. The place was left clean and tidy and all rubbish cleared away. I would definitely use Alex again and recommend him to others.
