Windows & Doors (uPVC & Metal)- 13 Jun 2024
Job done promptly and within the budget required. The window was put in place so quickly I didn’t have a chance to wipe the dust of it before it went in! Would suggest the fitter carries a cloth with him to wipe fingerprints and bits off the window before installation but really a small thing considering. Overall very happy with the job done. Thanks.

Bathroom Fitting- 22 Sep 2025
I recently had my bathroom completely renovated by Zsolt and Mario and the experience was outstanding from start to finish. They were professional, punctual, and incredibly skilled—nothing was too much trouble, and their attention to detail was second to none. One of the highlights of the project was the walk-in shower they installed, It’s beautifully tiled, and gives the bathroom a sleek, modern feel. They kept the workspace clean, communicated clearly throughout. Zsolt clearly take pride in their work, and it shows in the final result. The bathroom looks fantastic and feels like a real upgrade to the home. I wouldn’t hesitate to recommend them to anyone looking for trustworthy, high-quality builders. Thanks again, Zsolt and the rest of the team, you’ve done a brilliant job.

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!

Gjon and his son Julian did an amazing job tiling our kitchen floor. They were prompt in communications and completed the job within the agreed time. Left the job clean and tidy after themselves. Will probably hire them again to install a splashback later on in the project.

Extensions- 5 Sep 2019
One of the best builders I have ever worked with. PMB take great pride in the work they do and finish to a exceptional level (even better than a lot of premium and expensive builders in the industry). Colin's knowledge about all aspects of building work is unmatched and that shows in the end product that he and his team delivered for me. PMB did a full refurbishment & substantial extension (everything knocked down except 3 external walls) - ground floor ext, first floor ext, loft extension, full re-wire, plumbing, gas, UFH, walls, plastering, fitting, decorating etc. His prices are reasonable and he advised when unexpected costs come up so I could make a decision on what to do. I will definitely use him again.

I engaged Edi to work on a full renovation and refurbishment of a 4 bedroom detached house with front and back gardens on Blackheath’s Cator Estate. Edi did an extensive amount of work, including stripping out; plumbing; plastering; windows installation; carpentry; and decoration. In addition, after commencing the property work, once the scaffold had been erected, following sensible advice, Edi and his team replaced the roof and fully insulated the attic; fitted additional electric points; rebuilt the garden patio; and replaced the flooring throughout, in addition to other important jobs including re rendering and pointing of chimneys, building new wardrobes in the main bedrooms; and upgrading the radiators. A new kitchen, and two new bathrooms have been fitted. The kitchen redesign meant knocking through a wall with the lounge to create a larger space. Edi is a highly skilled craftsman, who thinks creatively as he works to make best use of the space, including shelf fittings, and additional lighting for example. He has built some beautiful wardrobes, and the internal decorations have brightened up what was previously a rather shabby looking house. In addition to the above, I wish to commend Edi for his professionalism, courtesy, and passion for doing the best work possible. On all the site visits I attended, and every time I spoke with him on the phone, it was striking how much he cared about the work that he was doing, his desire to ensure that the house would look the best. I always left site visits with the feeling that he cared so much about the house that he could be safely relied on to give the best advice to enable us to make the right decisions. I also noticed that Edi and his team would take the upmost care to keep the property safe, tidy and in good shape throughout the project. He can be fully trusted to look after any site he works on. He is intelligent and careful when it comes to safety and security. It has been a pleasure for Edi and his team to work with us over a period of around 6 months, and he did so much to reduce the stress of a significant project so that we could always rely on him to work methodically, patiently and sensibly, and to make best use of the resources available. His pleasantness shines through, and everyone I know who has spoken to him has always provided me with the most positive feedback I have no hesitation in recommending Edi to anyone who wishes to engage him for future projects, and is most deserving of the good words that I and others that work with him have to say about him.

Tiling- 16 Feb 2026
Luis did an excellent job on my bathroom. He had to do a lot of prep work before starting the tiling, including rebuilding the floor and repairing the walls. At every stage he explained what needed to be done, ensured that I wanted to go ahead, listed the materials that would be needed, and the cost. It made a huge different to me that Luis was willing to source and purchase all materials; he checked in with me from the suppliers as to choice and cost, and sent receipts for every penny. I cannot recommend him highly enough, for his knowledge and expertise, his honesty and hard work, and also for being such a lovely person, nothing is too much trouble. I am delighted with my new bathroom, and am planning more home improvements with Luis, when he is free again!

I've used Facundo's team to install a new shower, including wall and floor tiling, massage jets, and concealed shower equipment. Facundo was the person we dealt with at all times, although someone else was assigned to do the job. The quality of the work and finish is extremely good. I was also impressed with Facundo's professional attitude at all times, being very polite and respectful, as well as proactive in addressing any potential issues affecting our planning and execution. Highly recommended.

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.

Tiling- 25 Jul 2025
Shiv builders did the tiling for my bathroom. The quote was easy and done via a WhatsApp video. Price was reasonable. The job turned out to be more challenging than we first thought with uneven walls and floorboards were quite worn however they found solutions easily. The team arrived on time and did an excellent job. Always left the place tidy and very polite and professional. I then had a few additional jobs round the house such as changing door handles and fitting light pendants which they happily accommodated and again did a good job. Will definitely be using them for future work.
