Extensions- 5 Feb 2019
We are in the finishing touches on our 6 month project for a double storey side, back extension, loft conversion, new roof & total renovation with Rapid Bee. We invited a few builders to quote for our job & found RapidBee to be on the money. They certainly were neither the cheapest nor most expensive. We liked them mainly because of their professionalism & the can do attitude & knowledge. Whilst other builders tried to talk us out of some ideas we had, Adam & Saulius were happy to incorporate all our requirements & offered further options to make things better. It is refreshing to speak to a builder who doesn’t complain but offers good updates & offer solutions to problems. They employ an extremely hard working team that show great attention to detail & want to do a good job. The guys dealt with our idiot neighbour professionally & avoided confrontation & Building control on a few matters & Adam provided us solutions before he even told us about the problem. We added a few optional extras along the way & whilst they weren’t cheap we knew they would offer good value for money. They supplied all our windows of a top brand product at a competitive price that look absolutely stunning. They are a few weeks ahead of schedule, an outcome rarely heard of amongst builders. They prepared a clear schedule up front which made it easy to keep track of cash flow on work completed. We actively encourage anyone to get a quote from them & have a conversation with them when comparing builders

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.

Extensions- 11 May 2018
After a rogue builder left me with 18 (eighteen) structural issues. Lez and his crew came in transformed my failed extension into a masterpiece. All aspects of the job was done to the highest quality and utmost care and attention to detail was shown to building control needs. They cleaned up after every day and made sure the house was habitable, as I had to live there. Every aspect of the build, from the carpentry, plastering and tiling was first class and their recommend electrician and plumbers were from the same stock. Total professionals. My only regret is that I did not use this builder the first time. The prices were reasonable and even building control had good word to say about their work. Thanks Lez

Very few tradesmen can engage in a detailed, professional and friendly manner. They took out an old kitchen and replaced it with a new one - which the helped source at below market cost saving us in excess of £5000. Right from conception to finish, there was full transparency of the costs and crucially at the end, no cost overruns. Definitely five stars and will reengage again for other building/renovation works I have planned.

Kitchen Fitting- 19 Mar 2024
Highly skilled, professional and courteous Nik responded quickly to the job request and promptly confirmed the appointment for doing the work. During the initial discussion he did not try to push for un-necessary changes. He completed the work as per the requirement even going out of his way to source parts that were not matching. The work was fiddly and took longer than expected but Nik was professional about it and persisted with it on the committed times and cost. On completion, Nik tested everything was in order and left everything neat and tidy. We are looking forward to working with Nik again on the next set of changes in our house.

Bricklaying- 24 Apr 2019
Jake and Harry did an amazing job with our front wall and fence in the rear garden. We got three quotes for the job and they were the cheapest but also came across professionally. It wasn't a straight forward job, it was was using reclaimed materials that were varying size and shapes. I was also quite particular on the look, I wanted the brickwork to match our house, they took care to match the pointing and bricks but offered advice on how we could save money whist still getting the look we wanted. They arrived everyday on time, they were reliable, honest and extremely hardworking. They also kept us in the loop throughout the work making sure we were going to be happy with the end result. I have already recommended them to friends and will use them again for our next project. Thumbs up from us!
