A stone, catapulted from the lawn mower, completely smashed the fixed window of our patio door. We obtained a few quotations from local companies, including the firm which initially had installed the patio door, which turned out to be the most expensive. The quote from Alex Dobson Windows and Doors Ltd seemed reasonable and we are pleased to have chosen this firm. Mr Dobson arrived on time and carried out the job quickly and professionally. He also attended to some other windows which required re-balancing. Again he remediated the problem competently. Overall, he carried out all the jobs to our complete satisfaction and we are very happy with the service we received. We certainly would use this company again and can highly recommend it.

Triple Glazed the whole house (17 windows) and a new front door Moved into new area with no Knowledge of good tradesmen. Came across Alex Dobson. The Outfit understood customer focus and conception to completion. We found him patient, helpful and knowledgeable on design and product. Comfortable to go with him against the big boys in the industry based on cost and trustworthiness. Excellent at what he does and tidying up after himself. Completed within the time promised. When we called back over a manufacturing fault Alex turn the next day and promised a replacement window. One the best tradesmen I have ever dealt with, no stories, no shortcuts. A mutual respect all round. Happy to recommend him to my grandmother and others.

Alex Dobson personally replaced all the windows and doors in our 1970's detached 4 bedroomed house. This included a new front door, a pair of very large patio doors and triple glazed full wall sized window. I would highly recommend Alex Dobson. His work is of a very high standard and he works very hard. He ensures that each room is completed in a day, to minimize disruption and discomfort. He is helpful and courteous, always arrives on time and completes work within the agreed timescale. He does not put you under any pressure for extra work. He goes the 'extra mile' to ensure customer satisfaction; in my case he created, from scratch, a neat platform for my cat to help her access the cat-flap! The materials he uses are of high quality. The end result was excellent. A terrific contractor!
