Dennis Laycock - 20/07/23

Very happy with their products and service. Apart from a very slight glitch on the order, this was very quickly sorted. Cannot thank Danny who did the fitting, he did a supurb job with real attention to detail. Both Dave & Ian I met and found them approachable and amenable and only to happy to ensure satisfaction all round. Would recommend anytime.

Morton C. - 15/11/22

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

Laura Moody - 10/10/22

Had a large garden room built and decking area by D&I ...can honestly say David and Ian have been nothing but accommodating to our needs. Been absolutely fabulous with us in every way. Also a big Thankyou to the fitters Jason, Brandon, & Terry for weeks and weeks of hard work.

Terry Vaile - 01/09/21

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

Lucie Evans - 03/05/21

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.

Jillian Butler - 05/11/21

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!

Sue McGlone - 23/10/2017
