Bricklaying- 12 Nov 2016
Dear Brian I have tried to contact you on several occasions to complete the job. I really do not wish to leave negative reviews all over the Internet. Will you get in touch? Just ignoring the situation will not go away as I am now in receipt of your insurance documents and want to resolve amicably. I put you on notice to get in touch within 7 days. If I do not hear back I'm afraid I will have to start the legal processes as you give me no other option. I hope to hear from you within the allotted timeframe and do hope we can avoid litigation in this circumstance. Thank you. Dawn

Hard Flooring- 7 Nov 2017
I hired Alin to install laminate flooring within a quick time frame. Alin was quick at replying and scheduling in a date. He gave good advice to suit our needs and worked fast and efficient. He has always been professional at my home. Alin got all the work done within one day which I was delighted with. We are very happy and confident in him so we have hired him back to do many other jobs in our home.

Extensions- 13 Oct 2023
KBL recently completed a side infill extension for us that involved a lot of complex hurdles (e.g., requiring special foundations because of a Thames Water waste pipe and steel beams). In hindsight, we were very lucky to have hired them because they made the whole experience stress-free by explaining everything to us and handling our neighbours, contractors, structural engineer and building control for us. The amount of digging in confined spaces and hard, physical labour they put into this job is amazing. The extension looks great, is solid, warm and watertight. The wetroom they built inside it hasn't had any problems - plumbing is working great. Their plastering quality is excellent. We had to live in the property during the 4 months of construction but we felt relaxed and 100% trusted KBL to respect and care for the house. They have a lot of experience, know the building regulations, use quality materials and methods, they answered all of our questions with patience and always responded to my phone calls + texts quickly. They're so good that we'll give them an additional job to do which we originally planned for in spring 2024. Everyone we know wants KBL's contact details and we definitely want to ask them back for future work.

CAD / Drawings- 23 Sep 2020
Marius has been doing a great job and put in an extra effort to ensure we were happy with the outcome. I can not recommend Marius highly enough, especially as he managed to fix an issue with the council that we had from someone else drawings. He was patient and very well prepared. Went an extra mile and gave us different ideas/options. He was flexible with timings and most importantly with price. Had by far the best quote and did an exceptional job.
