Extensions- 3 Jul 2024
Just had a double story side extension built with loads of internal alterations carried out. Andy and his team are a brilliant bunch of lads, very approachable, clean and extremely hard working. The standard of work is first class and I would have no hesitation in hiring them for any future work. I honestly couldn't recommend them enough. In a world of cowboy builders, these guys are certainly not! It was completed on time and within budget. Andy has a great vision for planning and will tell you if better alternatives are available, he and his team have transformed what was our small family 3 bed home into what is now completely suited to our needs with 5 bedrooms, an open plan kitchen/living room, a snug area with separate utility area,downstairs toilet and an ensuite. If your thinking of having building work done, creation building services are the complete package. Thank you for transforming our home life.

Groundwork & Foundations- 4 Jun 2026
What a pleasure to have L&E Drainage & Groundworks do our Job. Very friendly, hardworking and dedicated guys. Even without their van they still made it to our job in their cars with their gear in the back. Constant communication and updates during the Job. They were on time every day even with a long commute. They dealt directly with the cabin installation company for us to make sure we got the correct information and the Cabin installers also have the necessary information for their part of the job to follow. The guys were very flexible with the changes from the original quoted job and at a perfect price. Cannot recommend them enough, Thanks guys appreciate your work.

Extensions- 21 Aug 2020
Paul and his team completed a fabulous kitchen extension in April this year. I would highly recommend Paul and all his workmen, especially as we were without a roof as we went into lockdown! They worked tirelessly during difficult times and even when materials were impossible to buy, they found a solution. Paul’s communication is excellent, unlike past experiences with the building trade. They always turned up on time, cleaned the site daily and were an absolute pleasure to have around. The price was great value for money, excellent workmanship, coped with our attention to detail and loved our two dogs! I would have absolutely no hesitation in highly recommending Paul and his team. I would never use anyone else for future projects. Thanks Paul. Maxine

Extensions- 25 Jan 2019
I love my extension very much but I would not work with John again which is ashame because I have so many more plansfor my house. There was times where I felt his attitude to myself and the people working for him was rude. Also at the end of the build he did a couple things that I was not happy with, like leaving a wall of electrics from the old kitchen which had been plastered and now had to be damaged In order to remove the unwanted electrics. He also left a radiator pipe on the wall and didn’t put it in the new wall that had been made. His cost was fair but felt that there was a few things that could have been better and if he had of been more professional I would have had him back to build my porch.

Restoration & Refurbishment- 27 May 2019
Matt did a fantastic job fitting in part of this work into his schedule. Matt and his crew poured a new concrete floor (plus insulation and screed) for my kitchen renovation. Matt was great at dealing with the Birmingham building regs department too, he does things quickly, and by-the-book. Massive thumbs up!
