Gurpreet fixed two steamed up windows where the seal broke. It was originally for 1 but the quote was excellent and offered the second for a small amount. Excellent work. Great price. But not excellent timekeeping or communications. I had to chase him several times. Most importantly, Great job. Neat and very polite. Will choose again. Thank you.

Had a quote for roof repair which included for 1 missing tile, re fitting existing tiles, repairing flashing and gutter cleaning did not accept quote. On advice from another roofer just had the one missing tile replaced since there was no evidence of any leaks inside the loft or 2nd floor ceilings.

Ion did a wonderful job on our bathroom. He completely removed the entire existing bathroom back to the joists and rebuilt a beautiful shower room. I found him to be honest, trustworthy, hardworking and reasonably priced. I couldn’t recommend him higher.

Fouad and his team did a fantastic job of our Victorian gate and fence, replacing a decayed lock and painting the railings to look like new. He also refreshed our outhouse. Super service, polite, efficient and friendly service. We would definitely use again, thanks Fouad and the team!
