Incredible Experience Meets Excellent Service
You might not believe that we started in 2009. But our business owners Dave & Ian decided to turn their experience into a business, and now we’re one of the best installers in South Yorkshire.
Part of that has to do with our belief in the fact that our customers come first. We started in Barnsley and expanded to other South Yorkshire areas, now covering most of the area. Our expanded product line means that we can offer just about any window design in any material. That’s more than most of our competitors can say.
It’s not just a business to us. We deliver top quality service and top quality products. We offer the newest materials and state of the art designs so that you never have to worry about mould, draughts, or ugly windows again.
But we have accreditations from FENSA, the Federation of Master Builders, and Which? Trusted Traders. We comply with building and council codes, and are vetted for customer satisfaction. It also means that our business has been credit checked, for your assurance. Furthermore, our accreditations mean we use improved materials for energy efficiency. Which is only a boon for homeowners.
Our business owners, Dave & Ian have over 50 years between them. And that’s not including our professional fitting team. We believe that our experience will make your installation easier, quicker, and more painless. We’ve developed a few core principles of our business over the years. And that includes making sure we put our customer satisfaction first.
When you look through our website, you’ll notice that we use products with thermal efficiency and that are fully weatherproof, colourfast, and stain resistant. We want you to come away from the installation happy with the product and the process. And we think that your South Yorkshire home deserves full weatherproofing so that you save money in the long run.
Top Notch Service
At D&I we pride ourselves on giving you great customer service. Our Barnsley team is here to answer all of your questions. And you’ll see from our reviews that we’re an accommodating and helpful installation service. We like to make sure that we listen to you, without pushy sales tactics, and troubleshoot concerns before they become a problem.

Conservatories, Orangeries, & Garden Rooms
Improve the value of your home when you choose D&I to install your conservatory, orangery, or garden room. We offer Victorian, Edwardian, lean to or other bespoke conservatory designs. And you can talk to us more about tiled conservatory roofs. Our garden room installation is a quick and easy service for those looking for garden offices.
We all know how irritating old, single pane windows can be. Draughty, warped, prone to mould, they can be unsightly and cold. When you decide to install new windows, you’ll get rid of those cold spots and reduce your chances of getting mould. But most importantly, it will reduce your heating costs.
Double glazing is now industry standard, as we strive to improve the energy efficiency of windows and doors and reduce our carbon footprint in our homes. But when you look through our designs, you can choose glazing thickness as well.
Of course, D&I offers triple glazing on almost all of our products. That way, you can improve your Window Energy Rating (WER) and the longevity of your product. You won’t have to worry about condensation or draughts when choosing new and improved materials from D&I.
Windows & Doors
Our experience has taught us how important it is to have variety. You can find uPVC casement, flush casement, tilt & turn, or sliding sash windows. We also offer aluminium tilt & turn or casement windows. And when you contact us, we can talk more about bespoke timber windows.
You can also find Solidor composite doors, patio doors, and French doors. Our aluminium doors include entrance doors, patio sliding doors, and bifold doors. If you’re in the market for garage doors, look no further. We offer a wide range of designs and colours, which you can read more about on our product page.

I am very impressed with d&i windows. From start to finish they have been excellent. Kelly was very friendly when she came to quote, the surveyor was very friendly and knowledgeable and the fitter was very good too. After shopping around, both the wait time and price was the best in Barnsley. Really happy we chose them. Will definitely recommend

Gave D&I a call after struggling to get a ramp done for my mother in law who has been diagnosed with motor neurone disease and hasn’t been able to leave the house for a year. They immediately got on with sorting it and it wasn’t an easy process but Dave never stopped planning it and came up with a solution, They had black composite decking with a ramp and it looks absolutely beautiful ,cannot thank you all enough for everything you’ve done an absolute brilliant service

Anyone looking for new Conservatory with a light weight tiled roof look no further. These guys do a excellent job, so organised all the trades followed each other, even Covid 19 only caused slight delay D & I were back on the job as soon as safety allowed. I doubt you will get a better price anywhere else either.

Would definitely recommend. Came round to offer quote quickly. No hard sell (didn't spend hours trying to wear me down like other companies). Fair and competitive price. Very helpful in organising a fairly fast turnaround to fit in with our other building work. Guys that came to fit windows did a really neat job, took care to put down dust sheets and also tidied up after themselves. Windows look great. Certificate arrived within a couple of weeks as promised. Thanks D&I!
