Highlights
“Daniel repsonded to me almost immediately, measured up the windows same day and sent me a quote the next. Very happy with the work completed. He was on time and finished replacing the window units much quicker than I expected. All together super efficient and good quality. Daniel was really friendly and happy to help with any questions. Would recommend to my friends.”
“I found Dan's details on Trustatrader as I needed a number of sealed units replaced. After our initial meeting and obtaining the estimate of costs, I decided to have all the sealed units in the house replaced and the style changed, giving my property a fresh new look. Not only did I find the costs very reasonable, Dan & his colleague are very approachable & knowledgeable and did a great job for us. Highly recommended, and Dan also carried out a couple of extra jobs for me that hadn't been requested, but needed fixing. Thanks again Dan,”

I recently had the pleasure of hiring Dan for some double glazing repairs, and I couldn't be more satisfied with the experience. From start to finish, Dan proved he is a professional, with a huge commitment to quality customer service. Dan took great care to ensure that the work area was kept tidy throughout the process, leaving no mess behind. He provided a clear explanation of the repair process and the estimated timeframe for completion. There were no hidden costs or surprises along the way. I found Dan’s fees to be very reasonable compared to other quotes I had received, and he offer’s excellent value for the quality of service provided. I wholeheartedly recommend Dan. His exceptional service, tidiness, honesty, and reasonable fees set him apart as a standout professional in his field. I will definitely be reaching out to Dan for any future repair needs and confidently recommend his services to friends and family.

What to check before you hire
Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.
Be wary of high-pressure 'today-only' discounts and a salesperson who won't leave. A reputable window or door firm gives you a written, itemised quote you can take away and compare against others.
Never pay the full price up front; a modest deposit with the balance on completion is normal. Ask what deposit protection or insurance-backed guarantee you get if the firm stops trading before fitting.
Get the specification in writing (frame material, the glazing units and their energy rating, and any trickle vents) so you can check you got what you paid for.
