Bathroom Fitting- 10 Nov 2013
Andy and his team did a good job replacing our bathroom and cloakroom. The job overran due to a couple of logistical problems with different tradesmen, but Andy did his best to minimise the disruption. Good communication and accurate quote, which was stuck to. Overall, we're happy with the outcome.

Extensions- 9 Jun 2016
Celli Property Care did a very good job. They undertook some structural work for us; knocking through a wall, dismantling and underpinning a chimney breast and installing beams to open up our downstairs living area. All the work was done professionally and signed off by building control. They installed 2 new bathrooms, a new kitchen and did all the plastering, tiling and painting and decorating. They also renovated our floorboards, which now look amazing. The communication was excellent throughout, with Celino the project manager always going the extra mile to keep us informed and discuss options and programme. The builders were also very considerate. We are very happy with the end product. I would recommend them to others. Thanks Celli Property!

Bathroom Fitting- 30 May 2022
Mohammed Huda and his builder were professional and quick to attend our job –– recommend! The communication was fast and professional. Mohammed provided a detailed quote (our job had to go through insurance) that is fair and transparent. The builder who came around, Jafa, was very respectful to our things. We were able to trust him from the get-go and had a peace of mind when he was working. He works incredibly hard and is methodical in his process (e.g. painting ceiling first, then walls, so to avoid splatter unevenness). They responded to our requests quickly and fixed things we weren't 100% happy with. The team finished the job ahead of time, and gave us tips for refurbishing in the future. Very happy and highly recommend!

Restoration & Refurbishment- 28 Apr 2024
I highly recommend these people if you want to be fleeced, taken advantage of, treated appallingly and work left unfinished. The standard of work is below average. If you want high quality finishing do not come here. I’ve had to spend a lot to redo a lot of their mistakes and mess. If Jerzy could charge you for every single nail he would, so beware. And when you challenge, they get aggressive and nasty. Very unprofessional. Do yourself a favour and keep away. So thanks Jerzy and co for a load of stress and rubbish. I am happy to talk to anyone and advise against these people.

Mario was an absolute gem from start to finish. After a leak left our only bathroom out of action Mario came in and managed the full project to perfection (and also had a great tiler and electrician who did some other works). Six months on and I cannot fault any of the works. Highly recommended.

Lovely father son business, professional, friendly guys. I asked them to build a plasterboard wall in order to create an extra bedroom in my house, the wall was finished well, within two days and they charged me a very reasonable rate, as a young women in business I find that tradesmen often try to overcharge me but these gentleman did not. They also took a look at leak that had occured which another professional plumber failed to solve and tried to charge me over £200 just to take a look! I have and will book them on a number of other jobs.
