    New bifold door fitted. John arrived on time and was very friendly and professional. Brought dust sheets and cleared everything up afterwards. Really pleased with the work.

    Fantastic!

    Posted 01 February

    We had our horrible broken sliding door replaced with lovely French doors and side panels. Debbie was great, very friendly over the phone and organised everything perfectly with great communication throughout. The guy who came to measure up (can't remember his name sorry!) was very friendly and stopped for a coffee and a chat about Lincoln City! The fitters did a very good, meticulous job, taking around 3 hours to do the work and cleaned up the minimal amount of mess they made afterwards! From the first quote to the doors being fitted was around 6 weeks. All in all, a great company!

    A brilliant job done

    Posted 19 January

    Hugely impressed with Diamond Glazing, recently had a large single story extension and partial garage conversion completed. From the first interaction to the last, it’s been professional and thoughtful. Particularly impressed with problem solving and building relationships with neighbours to help move along the process. Any issues have been swiftly dealt with, as with any project there will be hiccups but so impressed with how they were overcome.

    Window to French door conversion

    Posted 02 January

    I cannot recommend Diamond Glazing enough. They were polite, professional, and efficient throughout the entire process. They carried out a window-to-French-door conversion, and a few weeks later returned to replace the front windows of the property. The workmanship is excellent, the pricing was very reasonable, and I am extremely happy with the final result. Thank you for a great job

    Great company good values

    Posted 04 December 2025

    What a delight to deal with this company We needed a new conservatory roof and the advice we were given from John saved us money and gave us the best solution All the guys were great and it was obvious they are all very competent in their own areas of expertise Debbie in the office kept us informed and up to date throughout the process Nothing is too much trouble, have no hesitation in recommending them

We are a family run business based in Lincoln and cover Lincolnshire.

We are very proud to say we have been going strong since April 2000 when we first did our door-to-door flyer drop to kick start our business. Little did we know how many leads that would get us. Sometimes it's good to go back to basics and do old school!!

John the main man here has been in the business for over 40 years, so all our staff have been trained to an exceptional standard.

One of our key selling points is that we are a family run business, you get a personal service from us, we don’t do pressure sales ever and we don’t ask for a deposit, unlike other larger companies.

We don’t employ salesmen; John is usually the man who comes out but sometimes you get Debbie, both professionals in helping our customers choose their designs and offer amazing advice as they’ve seen it all. We try to get in and out as quickly as possible so not to disturb you for too long, we’d maybe stay for a cupper if offered!!

We do all the usual, windows, doors, conservatories, single Storey extensions, garage conversions are one of specialties, but we also offer classy pergolas for those cozy nights outside as well as replacement roofs for those old tired existing conservatories either our light weight metro tiled roofs or flat roofs with sky pods all are fully insulated and plastered to turn your once cold unloved conservatory back into an inviting cosy room for summer or winter

We also know it’s never easy having to have tradesmen in your home, which is why we take every care with your home, we clean and tidy up after we’ve finished, that’s if we make any mess of course!!! we respect your property as you do.

We don’t do much in the way of advertising so having countless returning customers over the years is testament to our high standards snd the amazing reviews we get left.

With friendly, helpful office staff, we are always here to make your home improvements run as smoothly as possible.

Another plus when dealing with a family run business, we don’t just operate from 9-5 Monday to Friday, Debbie picks up out of hours calls and emails throughout the whole week so if you have an urgent query it’s not unisual to get a text or email while your watching the soaps!! so why not give us a try if you want a personal service, no pushy sales, no signature or deposit given, you won’t be disappointed!!
