RS Property did a brilliant job on my bathroom; very professional and good communication with Roger throughout the project. I gave them a tight timeline and challenging materials and they worked well to get the job finished earlier than expected. They even took my bath and WC back to B&Q when they saw a small crack in them! Would highly recommend RS Property

We used J.A.M Home improvement for our new home redesign and renovation project. we had big plans and the building team headed by Ivan was very helpful at giving us ideas and solutions to our vision. We re-floored the entire house, installed new appliances, a new kitchen, re-painted, re-paved the driveway, re-modeled the bathrooms and re-modeled the garden. From start to finish J.A.M were professional and adaptable to our changing design ideas. I would highly recommend their services to anyone.

Oliver and team did a great job with our front drive. The design and outcome were closely matched, quality is good and the project came in exactly on budget / quote. The project included multi-leaf automated sliding gates which had some unique aspects to the design requirements, but Oliver found the solution and it works well. Would recommend Oliver and Tree & Stone team to others. Satisfied customer!

I can highly recommend Rob and his team at Made Build Interiors. They have just finished work on our Bathroom, Kitchen, Living room and Dining room. They have completely transformed all of these rooms and we are extremely happy with the end result. Rob is a great sounding board for creative and structural ideas and has a good eye for detail and design. They kept all work areas clean and tidy and had a friendly but professional attitude. We will definitely use them again for future work.

Job completed October but by November asked for them to comeback as new sink put in was leaking badly and blocked - not flowing out but doing well coming up from the washing machine…all connected. Said would be back, didn’t. Rang from my night shift no answer even though he was using What’s app…now paying again for what they didn’t come back and sort out. Also, 2 cupboard doors came off their hinges, new tap had to be tightened, was v lose… and yes, I could easily have had my Belfast sink put in too Hoti.

I had some fencing replaced, some crazy paving taken up and gravel put down and a gate erected by these guys. The work was done to a great standard with minimum fuss and in a timely fashion. They do not use any sub-contractors so you know who you are dealing with throughout the project. The site was left clean and tidy too so I am more than happy to recommend SNC Building and Maintenance Service for similar jobs.
