Bathroom Fitting- 10 Nov 2020
William and his team were very good and installed an entirely new shower cubicle in place on an existing cupboard in a bathroom with previously only a WC and sink. I am delighted with the result and will be using William and his team again for other projects across my rental portfolio.

Bathroom Fitting- 14 Mar 2025
My previous bathroom fitters did a very bad job with the bathroom and cloakroom toilet and left it unfinished. I am so glad I went with JM Building service as Joe and Martin completely transformed both rooms. They rectified the previous fitters errors and completed the rooms. Joe didn’t just rush through the job to get it done quickly—he took his time, ensuring every detail was finished to a high standard. He worked meticulously, making adjustments until everything looked exactly as it should, rather than settling for ‘good enough.’ His dedication to quality and precision was evident throughout, and the end result speaks for itself. As well as being very good at what they do, they are friendly, reliable, trustworthy and hardworking. I have already booked them in for another job and requested a quote for another. I highly recommend JM Building services for their professionalism and craftsmanship.

Tiling- 3 Oct 2018
Goni and his team did a fantastic job. He came around to quote promptly, and the quote was competitive. The tiling itself was done to an exceptionally high stand with a precise eye for detail. He also did a couple of other extra jobs - fitting a doorstop, replacing a radiator so the tiling was perfect, and fitting a tiled upstand where the old skirting boards were. I am deeply impressed and have no hesitation in recommending Goni.

A & Building in association with Home Snag4u. I pride myself on doing a good job and if it is not good enough for me to accept in my own home then it is not good enough for my customers. Advice to all customers when requesting any information regarding building work, alterations or repairs, please provide as much information as possible. Example is it a new home or older home. As you can imagine the difference in work between the 2 can vary due to building methods and materials. Also if possible try and upload some photos that capture the work you wish to have done as this will enable to provide you with the best estimate possible. Facebook Home Snag4u 0*7*8*6 6 7 5 3 0 4 9
