Based on my experience I have no hesitation recommending BCB Building Services who came recommended to me prior to this work by word of mouth. I needed to carry out modest renovation and remediation works on a newly purchased period property requiring many trades; general builder, scaffolder, plumber, plasterer, roofer, landscaper and damp specialist, etc. Brad and BCB team promptly provided a quote and, essential for me, agreed to source and project manage the diverse trades required to complete the work. They are busy but worth the patience and short wait necessary to get the work done by them. The workforce were professional, tidy, courteous and organised minimising disruption during the works and leaving the house clean and undamaged in their wake. The works were delivered per schedule and to a high standard and whilst not the cheapest, the pricing is fair and I believe the outcome represents tremendous value. Brad and the team remained pro-active beyond works completion and engaged actively in addressing the small amount of trivial snagging. They are now my go to for building works.

Bathroom Fitting- 21 Mar 2025
Zia and his team did a fantastic job completely renovating a main and en-suite bathroom. Out of everyone we got quotes from he inspired the most confidence due to his in depth knowledge of bathroom design and plumbing. He worked diligently on both bathrooms and all within a reasonable cost and timeframe. I highly recommend his services.

Tiling- 25 Oct 2017
I hired Indri to re-tile my kitchen floor and walls and do some plastering. He did a great job to the pre-agreed price, the kitchen looks amazing and my wife and I are very pleased. Indri is a good communicator, always answering emails and texts. He put in extra effort to ensure he got the right edging for the kitchen wall tiles and spend half a day driving round different merchants until he got the right product. Would definitely hire again.

Restoration & Refurbishment- 5 Sep 2020
Hubert and his team did an excellent job. We moved walls, relocated cloakroom, had a new kitchen installed, underfloor heating, megaflo and new flooring downstairs and everything that goes with it. They always showed up on time, neat and tidy and kept the overall timelines as agreed even though the refurb had to be managed during lockdown and we asked for additional works which they fitted in.

Savage Bros built me a single storey extension on the back of house with pitched roof, four velux windows in a vaulted ceiling, they fitted a new cream gloss kitchen with black granite worktops and turned my old kitchen into a new dining room. Richard also installed a new bathroom suite and downstairs toilet and finished by tiling and painting the rooms. Richard takes great pride in his work and he has great attention to detail, I cannot fault anything. He comes in early and works solidly all day, cleaning up at the end of each day. A true professional in all aspects of the job. We would recommend him, he is a lovely genuine man.

Extensions- 8 Mar 2025
Charles and his team did a brilliant job on my double garage extension. Start to finish Charles and his team were really polite and clean workers. Charles was always in contact with me and giving me updates daily and always kept me in the loop at every stage. Project was completed to a really high standard, a very reasonable price and in good time! It wasn’t the easiest build due to a water leak from Thames water nearby causing a mud pool but it was still completed in a great time frame! I can highly recommend them for any works!

What qualifications and experience do you have as an extension builder in Crowthorne?

An extension builder in Crowthorne should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Crowthorne?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Crowthorne extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Crowthorne extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
