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.

Restoration & Refurbishment- 26 Jun 2022
Tommy was a wonderful perfectionist and has done beautiful work in our stairway and hallway which had needed refurbishment for a very long time. It feels brand new. The flooring is perfect both in the hall and staircase, and the walls are now perfectly smooth and painted immaculately. Friendly and accommodating, we will be hiring again for more jobs in the future, undoubtedly. Thank you.

I recently hired LLC Projects Limited to refurbish my ground floor and add a new bathroom, and I couldn’t be happier with the results. From start to finish, the team was professional, reliable, and truly cared about delivering quality work. The new bathroom looks amazing, and the ground floor transformation exceeded my expectations. Communication was great throughout, and they kept everything on track and tidy. The crew was friendly, and they handled any concerns I had quickly. I’d definitely recommend LLC Projects Limited for any home improvement work—they’ve earned my trust, and I’ll be calling them again for future projects

Hired for a kitchen refit and other works including removing a wall to open kitchen out. Understood the job, and where appropriate offered helpful suggestions. Excellent communication throughout, I was always aware of the current status of the job. Work performed exceeded expectations - and I hope they will be free next time I have works that need doing.

Bathroom Fitting- 1 Sep 2026
Sadly…Still have the bath tap leaking. Flooded the bathroom and kitchen Broke the thermostat for the central heating. Condemned my cent heating and now need a new heater £4,000+ The freeze kit didn’t work and should have used the proper machine instead of a temporary Quickfit kit smh and then many times coming to do the job properly (even got a gas engineer that wanted to charge £150 for a job not done grrr)… £801 charged for a new sink to be installed… yes it’s a old flat (like said in the description). Very disappointed for an expensive job that’s not properly done, even now… can’t be bothered to call him back in case it’s more money. We come to these sites expecting true professional…

Bathroom Fitting- 20 Jan 2023
We highly recommend Mario & his team. They fitted a new kitchen & bathroom to a really high standard within a short, timeframe. They work hard, are friendly, professional & honest, my neighbour even commented on how considerate they were! Upon first meeting Mario we were impressed by how organised he was. He arrived on time with the description we’d posted on my builder & went through it methodically. We had A LOT of questions! He answered all of them & didn’t rush us. We received a competitive quote within a day as promised. It included everything we discussed & he quickly answered our follow up questions. We wanted an accurate idea of the cost of electrical work & Mario arranged for his electrician to come & inspect/quote before we’d appointed Mario the job. Our kitchen & bathroom is complicated, with lots of difficult angles. Damp, unlevel floor, unlevel windows, a low ceiling were uncovered in the bathroom. Mario did well to identify solutions, giving us expert advice. Pipes were neatly chased into the wall. Underfloor heating & LVT, tiling, grouting & painting all done to a very professional finish. He kept us informed of progress, checked our preferences & was patient when we had supply delays, finding ways to ensure the job finished on time enabling us to move from our temporary accommodation back home in time for Christmas. He promptly fixed some minor issues after the job finished. We highly recommend Mario & would use him again.

Don and Jake were terrific. Nothing was too much trouble and they provided work to a very high standard. They were extremely competent and I cannot recommend them highly enough. I have done many building projects and they were the first builders that I didn't fall out with!

We did a lot of research ahead of our loft build, and spoke to customers of the companies we looked at. We were impressed with Toma and her team from the outset, especially in terms of clarity and communication. We sat down with the project team at the start and walked through the week-by-week plan for our build, then a whatsapp group and weekly meets meant we knew exactly what was happening throughout. Our endless questions were responded to swiftly. Additional optional trade-ups (eg top-hung windows, larger bathroom window etc) were discussed and explained with context, sound advice (and clear pricing where nec) but always still optional. Toma's communication with the teams also seemed strong and continuous, with materials always arriving in time and ahead of when needed, no down-days etc - and importantly, the teams all seemed happy and were just lovely people to have around. I realise with hindsight too that the team's care and workmanship really put them a cut above many others in my area and the project remained on schedule. I wouldn't hesitate to recommend ICS for the whole package and in fact we've also chosen to use them again for a kitchen extension.
