Tiling- 10 Apr 2016
Kieran did an awesome job of both enlarging my loft hatch, fitting a loft ladder and both tiling and flooring my bathroom. He is super helpful and a really nice guy who will always do his utmost to make sure the client is happy. Kieran has also done work for two of my neighbours who can't speak highly enough of his work. I can recommend KVC 100% and will definitely be using Kieran again in the future!

Extensions- 5 Sep 2025
We are so glad we chose Mark and the team! From start to finish. Sorting the structural calculations, dealing with the building control department and co ordinating the contractors needed to complete the job. Great communication, trustworthy and a pleasure to deal with. In some ways we are sad that they have finished! Quality work, completed in good time. Scheduled payments as the job progressed. Running my own business I am always critical of other services. I can safely say there isn’t one thing I could criticise. Building control required additional specifications but Mark didn't charge us any extra. A man to his word and price. We are so happy with the end result. Would highly recommend Engwell Building services. Top people. Top job.

Landscaping- 19 Apr 2019
For many years I have had problems with the grass quality in the back garden with weeds and moss. This year I decided to have a patio and artificial grass laid to overcome my frustrations. Jamie from active groundwork services came to view the task I had initially thought of, with his experience in this type of garden work he suggested I go a little further and designed a plan to rejuvenate the area. What a complete difference and impact his idea had on the project, the end product was totally amazing. Jamie's quality of workmanship and finishing is of a very high standard, he goes out of his way to provide advice and suggestions throughout all stages of the work, and had a very helpful understanding attitude, this coupled with a competitive price, I would highly recommend Jamie to anyone, to a point that I would not consider any other firm before consulting him. There are a few other little issues/jobs I have in the front and side of the house which Jamie is kindly going to address in the near future. Thank you.

Carpentry- 15 Jan 2019
The standard of work was abysmal. The photos in the photo gallery must have been taken from someone else's site. Catalogue of errors. Where do I start. - Failed to follow the instructions on boarding the ceiling, instead boxing off part of the room. - Much of the insulation was removed, - The boards were not properly screwed down, leaving unlevelled floor board, with dips and rises in the floor. - Both the flooring and ceiling boards had gaps, which were filled with foam. - The work caused cracks in the ceiling below. - The original fitted loft door was cut. This was cut short. Then repaired by putting another piece of wood on top. The loft door is now two pieces of board stuck together, which is unsightly to look at. -Since the "job" was done the loft door does not stay closed, as the lock was not properly fitted probably due to the loft door not fitting. -The ladder is flimsy, the cheapest on the market. As the loft is high I have been told that the ladder is inadequate. I requested the receipt to return it. The receipt was sent to me after the 30 days that the ladder was purchased. The shop were it was brought refused to take it back as it was outside the refund period. The flooring is so bad it has to be boarded over, which is an additional cost. The plasterer had to screw down boards before he could start plastering.
