Restoration & Refurbishment- 13 Aug 2019
David and his team were excellent. They are always on time and very professional. They always cleared up at the end of the day thereby leaving very little dust or dirt around the house. No query or issue was ever insurmountable; the answer was always "no problem", which was a joy to hear when having such a large project to do. Each different team i.e. electrician, plumber, arrived exactly on schedule so there were never any delays. The end result was amazing. I highly recommend David and his team.

Loft Conversion- 26 Nov 2020
I would highly recommend Kaca Constrution, Elson and his team were extremely professional, polite and the work was carried out to an excellent standard. I am extremely pleased with the result! I heavily researched builders before choosing Kaca Construction. The service was brilliant! The team always arrived on time and completed each stage of my project perfectly. This was the first building project that I have done (a loft conversion - hip to gable with dormer). Elson helped so much – from project planning, to connecting me with reliable suppliers - his advice was always reliable, clear and priceless. Elson was also very flexible, he always listened and tailored the project to my specific needs. I found him to be very knowledgeable and experienced. I highly recommend Kaca Construction and would definitely work with them again in the future. Excellent service and top quality work!

Loft Conversion- 14 Apr 2019
We have recently had a loft conversion done by Dymek Builders ltd. Remarkably it was within our budget and time frame. We would describe Waldek & Dymek Builders team as very reliable and trustworthy. On more than one occasion Waldek did not go for the obvious and costly solution instead he gave us an excellent advice and save as a money. Waldek kept us informed throughout the project and the quality of work is excellent. Dymek Builders ltd is a professional, friendly and qualified building firm and we have no hesitation in strongly recommending them to anyone seeking a reputable builder.

I received quotes from multiple builders to build a garden office, and choose Teodor as he provided the best quote. His workmanship is top quality and he built me a fantastic garden office which I am enjoying immensely. Teodor was very professional and reliable, keeping me involved throughout the whole project. I will be using his services again in the New Year and can wholeheartedly recommend Teodor.

Florin extended and completely refurbished our 4-bedroom semi-detached house. This included extensive steelwork, underfloor heating, complete re-plumbing and rewiring, excavation, and an entirely new slate roof as well as varying extensions up to three floors high. I cannot say enough good things about his workmanship, professionalism and reliability. His workmanship makes a perfectionist like myself happy. He is also completely professional: even with our difficult neighbours he was always courteous and understanding, and even helped them sort out issues at a moment’s notice that had nothing to do with his building work on our property. And he is also thoroughly reliable. I cannot think of any instance where he committed to something and did not deliver — he even managed to finish all the work on our house ahead of schedule and on budget. We have been so happy with his work that we contracted him to build us a summer house as well, from scratch, and to complete revamping our front garden including elements of hard landscaping. Again he delivered flawlessly and we are very happy with the result. We also continually receive positive comments from people passing by and just seeing the front garden. We have used several other builders in the past on other properties, including far more expensive ones, and none compare to his level of competence, attention to detail in his workmanship, his complete professionalism and thorough reliability. Now that we have found Florin, we will never look for another builder again. I just hope once others experience what he delivers for themselves he will still have some availability for us in the future!

Blueline completed the work to the exact high standard i was hoping for, while remaining on budget and estimated timescales - the three things that were most important to us! They were punctual, practical, knowledgeable and willing to give advice when either needed or when something could potentially be improved. They were always available to talk through what was happening at every stage of our job, with any complications arising, and importantly solutions to any problems. They knew their stuff and got the job done without any hassle either. They even came back after the job was finished to shift some pipework which i had an extra requirement for. The best feedback i could give is that we will go straight to them for any work we require in the future, and have already recommended them to friends.

Alin was professional and did a good job. He had a couple workers who were messy and we spent a lot of time cleaning up after them. But they worked hard and did a good job on our garden.
