Shane, Ryan and Gareth made the effort of constructing my extension to a high standard. Shane, the foreman, was very punctual, methodical in his work and would not leave until he is satisfied with his work. He is the backbone of Matthew's Building Services. Matthew's Building Services is impressive and worth the wait.

Conversions - General- 7 Feb 2025
Stephen and his Team were utterly professional, their work was faultless and we couldn't be happy with the job. We had a wall removed in the kitchen which needed a support putting in, and a wall removed in the bathroom and a doorway sealed up. Right from my initial contact with Stephen we got got a good feeling, his quote was the most competitive but we had already decided to go with Stephen anyway as his experience, expertise and integrity were obvious as talked us through the job and what would be required. Their work was fast and to a great standard. We were very impressed with how clean Stephen and his Team managed to keep the house throughout all the work (especially as we have black mortar in the walls), they cleaned up throughly every evening and it made life so much easier on us.

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.

Extension Builder in Newport, Gwent
Started own business in a partnership deal in 2008 with long time friend who had been working as a soul trader for 6 years. We are now trading under the name of Orange Grove Construction and in this present climate have been very busy with continuous work ranging from extensions to renovating/loft conversions, kitchen fitting, bathroom fitting, wall and floor tiling, plastering and rendering, U.P.V.C, basement conversions, conservotories, fencing, garden walls, patio laying, fascia and soffits and guttering. When we set out, we only advertised for one month to pick up work, the rest of the work came in from word of mouth.

Conversions - General- 30 May 2013
Dave Phillips was brilliant. Friendly and accommodating, nothing was too much trouble. He converted our garage into living space, always solving the small problems builders face as they make progress. He has a really good network of reliable specialists for electrical, plastering...etc, all of whom he has known for decades. A perfect example of excellent small business. I have already recommended him to our friends and family, as a result he has lots of new business keeping him busy. Our friend's house needed full refurb, some very serious work, and Dave was available on the phone 24/7 when not at their house. As soon as we can afford to do more work on the house, Dave will be our first choice builder, in fact, we will wait until he is available to do any future work on our property.
