Had wood delivered. Did not turn up to start the job. I tried calling and it sounded like he was asleep. Would not take any further calls. I asked for wood to be collected as he is unreliable but it is still here.

Nico and the Greenbuild team are polite, professional, clean and tidy, hard and fast working and were a pleasure to work with. Having completed several renovation projects and new builds, I can safely say that this team was the best by a long shot. Highly recommended. I hope they are not to busy to start my next project!

Extensions- 5 Oct 2020
Billy, Darren & the team have just finished the single side and rear extension & refurb works on my house, and they've done a brilliant job! From the start, quotations we're received promptly and competitively priced. Communication for commencement of works (during COVID-19) was always going to be uncertain but, Billy dealt with this really well and scheduled the work in as soon as was achievable. From the first day on site it was clear the team have worked with each other for years and are willing to put the extra time in to get the build done quickly, but correctly. Communication throughout build was processed well and the guys are on hand to respond to queries and questions at all times. We had a delay in the project which was unforeseen, but we sat down and came to an agreement and the extra work was carried out quickly and the project was wrapped up in really good time. I wouldn't hesitate in recommending Innovation for any building or decoration work to friends and family as the end result of our place is stunning! Special shout out to Jordan, Fog, Florin (wood work wizard) & Joy for their hard work throughout. Thank you Innovation!

Extensions- 1 Feb 2019
Extremely satisfied. He happily goes the “extra mile” and his charges for such additional work are reasonable. Inevitably the odd unanticipated item arises in the course of the work and he discusses the options rather than making up our minds for us. His dictum that he does not leave a job for another before the first job is finished is reassuring - and fact. We have been happy to contract further work to him - including hard landscaping - on the completion of the original extension work, and are equally impressed with his performance in this.

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.

Joinery & Cabinet Making- 23 Aug 2019
Can’t recommend Alex highly enough! He built wardrobes into our attic eaves, altered some stairs, and fitted our new wooden hallway flooring, all to an exceptional standard and at a very reasonable price. He was professional, tidy, efficient and consulted me every step of the way to ensure the finished design was exactly what I was after. I’ve already asked him about doing some future jobs I was that impressed.

Kitchen Fitting- 7 Jul 2016
Excellent! We hope to use again! I cannot recommend Alex & Richard highly enough. We had a full kitchen/diner knock through and complete refit. They were an absolute pleasure to have working at our house. From the moment they came round to quote for the work, they were pleasant, prompt, clear and concise. They were able to start work quickly which was great for us. The professionalism and attention to detail was amazing. Always arriving on time, they often stayed late to complete their work which lasted just over 2 weeks. They are a credit to the building industry and themselves. Our finished kitchen/diner looks amazing. We are so pleased. Please do not hesitate to hire these guys - you won't be disappointed!

An extension builder in Guildford 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?

Your Guildford extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Guildford?

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 Guildford extension builder’s ability to deliver a result that meets your expectations.
