Very helpful and efficient
Customer Service
We had to call DG after our tilt and turn patio door stuck after putting out our Christmas tree. We were unable to close it, let alone lock it. Jan was very helpful and reassuring on the telephone and as they had had a cancellation a couple of engineers were here within a couple of hours of my call. Both wore PPE and very quickly and efficiently solved the problem. Thank you DG, you turned a bad start to a New Year into a warmer, drier one.

Triple Glazed Beauty
Customer Service
DG servicing supplied and fitted three new triple glazed front windows to our property. The value for money is unbelievable when comparing them to other suppliers/fitters. The quality of the product is superb, they look wonderfully modern and sleek. The property has been transformed aesthetically. Three fitters (including Dan the Manager) fitted all three in one day. Their workmanship was superb, they were respectful and tidy. A thoroughly excellent job and they come highly recommended.

First class service
Customer Service
Fast and friendly service, arrived exactly on time, the lady in the office who took my call was excellent, arranged a visit that afternoon, the 2 men who did the job, replacing the rollers on my patio door, were also excellent. Would certainly recommend this company.

Installation of replacement door locking system
Customer Service
The old UPVC door locking system broke in the locked position stopping the door from opening. DG were contacted and their team were on the job very quickly. The door was very old and the handle mechanism was also very worn and loose. The locksmith assessed the situation and advised that they could change the damaged mechanism complete with a modern equivalent. They left the door in a secure condition while obtaining the materials. Within a week they were back on site, the old lock and linkages removed and replaced with a complete new system within two hours. Good, friendly service, nice people to do business with.

A very happy customer
Customer Service
I had two jobs done at the same time: A) One of the French doors would not lock easily - whole door had dropped B) Double glazed single door to back of garage would not lock at all. The engineer and his assistant arrived promptly and assessed the problem for each door. Having explained the procedure required to fix each door, they checked I was happy for them to carry out the repairs. They worked swiftly and efficiently and cleared up after themselves, leaving me with two perfectly smoothly locking doors. I would have no hesitation in recommending this company. The receptionist was extremely helpful in arranging a visit at short notice, taking on board my time constraints. When it clearly would be impossible for the engineer to add my callout on to the end of the Tuesday, she phoned me to confirm that it would be ok for the engineers to visit first thing the next morning. I also used this company many years ago and found their service exemplary. I am delighted to be asked to complete a Which? review for this outstanding company.
