Just had windows and a sliding door fitted by Harry. What a fantastic job! From the surveyor coming to measuring up, customer service and the fitting- everything has been perfect and the quality of the finished job can't be faulted. Definitely recommend. I'll be using this company again.

LDG did a fantastic job on my windows and front door. Mark the fitter was very professional, all the finish and trim was left perfect and cleaned up afterwards.

Superb service salesman Simon was really friendly helpful and polite. Arrived on time was professional and gave a good quote.The installer Harry was just as professional. Arrived on time, got the job done in a timely manner and left the place clean after. All round great service and would recommend them to anyone asking about doors or windows.

From start to finish LDG deserve 10/10. Tony who came to give me an estimate was so customer focused and pleasant. That’s the first reason I decided that I was going to have them. I did have other quotes but Tony’s customer service blew them out it the park.The window fitters Paul and Lauren were excellent. Professional, friendly constantly keeping me in the loop of what they were doing on the day and making sure I agreed. They are an asset to the company. If you want windows/doors just go to the best and that really is LDG. Outstanding!!!

Simon our salesman was very friendly, not pushy and understood our budget. 4 windows replaced and the survey also revealed we needed some extra work we weren’t aware of to keep our house safe. John and Kallum our fitters done a great job, cleaned up well after themselves, were polite and done the job in good time. Many thanks again, Matt and Katie

Owen was a great salesman. Very polite and very friendly without being pushy or over bearing he secured the deal. Was advised of a 2-3 day install on the entire house. Obviously things run over and in the end it eventually went to about 2 weeks due to only working 4 days per week.We asked for 30 min notification prior to turning up on three separate occasions and not once did that happen. One day they didn't turn up at all. Once installed they looked great from a distance but when you got closer it was a mess. I'd probably be hopeless at using silicone - but so was whoever did this one. I think 3 out of 6 windows needed silicone taking off and redoing. After the panelling was added and re silicone it did look so much better and they wasted no time in getting things sorted out once notified.The welds on the frames are somewhat visible where the white has bled on the top of the grey. Most frames covered in transfer . Which all eventually can be filled in with a paint pen and the transfer can be rubbed off with a bit of elbow grease. They shouldn't really leave manufacturers before this is done but that's just my opinion. Some frames were scraped and scratched and handles scratched . These were flagged and these was rectified.Workmen we're polite and friendly and very easy to get on with. They cleaned up after themselves every shift and worked hard to get things done.The back door wouldn't lock at all. Had to leave completely unlocked overnight until someone could come and check it. Had to be readjusted and is now fine.One of the panes of glass on the patio door 'shattered' during installation so we waited around 4 days after the installation was complete for a replacement. Once again no 30 min warning just turned up at the door. As soon as this piece of glass was fitted - like literally 2 whole minutes of leaving the house - the phone then rang from the office asking to settle the invoice . Which is completely and utterly rude to be asking for money after all the crap that went wrong without checking the pane.Good job we didn't pay as the replacement glass we got had a massive scratch on the inside of the double glazing to which we waited another 2 to 3 days for that replacement.Finally almost 3 weeks from start date we was at 100% , the windows and doors look brilliant now and it was a definite improvement over how it was before we started. Ultimately when you spend this much money you just expect things to be perfect and right the first time. I can't help but think we could have saved a couple thousand pounds and got the same result if not better somewhere else. It's unfair to give any lower than a 3 and I can't find reason to give any more also.So I would say use at your own peril but please please check the work over and over again. In 20 years time - if they last that long - I probably wouldn't use this company again unfortunately and I wouldn't recommend to a friend or family . Maybe we just got a bad wave of hiccups based on the other reviews but that's my personal opinion.
