    LDG fitted a double glazed window upstairs with internal Georgian bars and also a new garage door and window.Excellent advice from the company rep and swift fitting from the company's own fitters.Highly recommend this company, the units have lasted well.

    I've recently had my house fitted with windows and doors. This is my second time using Lancashire double glazing and like my last house I am so happy with the whole experience. It was refreshing to see the salesman Chris Gabbott who I previously dealt with 15 years ago. It was an enjoyable experience with him as there was no pushy sales tactics, he listened to my requests and gave good advice. From sales to completion it couldn't have gone any better.

    Excellent experience with this company, had all windows replaced with the minimum of fuss.No high pressure sales technique just good advice and a good price,Surveying done professionally, both John and Calum fitted the windows to a very good standard, turned up when they said they would and tidied up afterwards.The plasterer and the sealer were pretty good also.Would highly recommend LDG.

    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.

    i wrote to you in jan-feb 25 on another site where you were advertsing.. you then hood winked me .after mentioning the quick service turn round. . you then took 2 deposit payments .(You fitted our large bedroom windows 5 units.The large breakfast room window. The boiler room & lavatory a few yeras ago.) when i;m very very ill. you then after deposit paid. place me on back burner for April 11. conned me by heather phone call.13.march25 out of blue. not in writing so no audit " best way to con a pensioner . is by then heather by a generic no reply no redress text. no reply. service no recall. another con no redress . then after closing of business on 11.04.25. a month later heard nothing. or to mention to me by cordial e-mail 'we are still coming to fit your badly needed rear door for access mobility reasons.' but hey the sales man got your money the fact your very ill and need the new door accessibility / mobility.. we couldn't give a thump ! the back door and 2 pains of glass. Nothing! no 'how are you this is our great LDG interim service.' WE HAVE YOUR DEPOSIT' . so tough . You now wait. Nothing like you still had not confirmed my installation date. . No ! we are a caring company.. it's 12.04.25 no installment no reply from heather or sales interim before during or after service team. I'm a very ill pensioner . which you have known all long. A Complete CON by heather plus whoever. You never wrote by e-mail, not even to mention- inform update or turn up. when a pensioner is very ill every aspect of life is amplified . like your woeful service. ..quote 'We specialise in making homes like yours more secure and more beautiful. We achieve this by using expert installers to fit British-made PVC-U windows and doors of an exceptional standard'...your standards are so good from the 13th march 25 you leave me in complete oblivion no contacts by heather sales production instalment at all. i wrote an email before i went for my after noon sleep.10.04.25 in between treatments. my reply came from a very nice man in Nepal he was on his holiday. i said i fuming . I've been conned. he was in NEPAL and wrote back, no one from LDG in uk did at all. show how nice tom is.when your very ill every aspect of liaison (i keep asking emails only as it's an audit. but hey anyway to not use an email by LDg is better as phone calls are audio, ) is welcomed . no liaison from either of the 4 office address on Thursday from Preston. they have pc. they have graphs production sales data. red flags accounts audit all on pc.wall charts. yet they can't write to a ill pensioner, to mention be honest that we are or we are not coming on the 11.04.25. we.ll just con you and run you ragged. what a load of hog wash. DONT USE LDG. they take your hard earned pension savings , drop you as your not important. YES i am very angry. IT DOE'S NOT Matter WHAT LYING CHEATING EXCUSE YOU USE. YOU HAVE NOT BOTHERED TO DO PRESENT THE SIMPLEST CORDIAL liaison with a ill pensionerSIMPLE CORDIAL BUSINESS TASK OF INFORMING -UPDATING A SICK PENSIONOR. THAT HE WILL BE HONOURED AND HAVE HIS INSTALLMENTS ON SCHEDULE . ABSOLUTE DISGUSTING ATTITUDE BY LDG.

    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.
