Tom Reilly recently fitted a kitchen for me and I am very pleased with the result. The work he has done cannot be faulted. Tom was reliable and came when he said he would. He was efficient and very clean and tidy. I would highly recommend Tom and I am, in fact, hiring him again to do further work for me.

Extensions- 25 Apr 2025
we recently had the pleasure of working with Leon building contractors limited, and i cant recommend them highly enough! They carried out a single story rear extension, an internal garage conversion and porch to the front of the house. On top of that they installed our new kitchen and toilet suite downstairs all finished to a high standard. From start to finish Vic and his team were amazing nothing was too much trouble and were always happy to do anything without a fuss. Their attention to detail was first class. It wasn't only us who was impressed but our neighbors commented how friendly, respectful and hard working they all were and have already asked for his contact details. Vic trade contacts also helped us with windows/bi-folds and quartz worktops all high quality at much cheaper prices i could find myself! Thanks again to Vic and the team for doing such a brilliant job, we have no hesitation to use again in the future!

Landscaping- 20 Jun 2024
From even before the job started I knew I’d made the right choice. The communication was truly 10/10, not too common nowadays. After 2 long days of hard graft in the summer sun the place looks a thousand times better, we’re dead happy and have met two great guys in the process 👍

Replaced a rotten external single door. The existing door frame was reused, as per request. This frame wasn't perfectly square which Alex had to compensate for. Alex arrived on time and completed the work without any unresolved issues, taking all offcuts and old door away for disposal.

Restoration & Refurbishment- 17 Jul 2016
Valter was very impressive on his initial visit with some exciting ideas for the house improvements and we had no hesitation in choosing Happy Building above the other two building firms who quoted. Having signed off on the budget and scope of work, Valter's team of builders arrived. We were hugely impressed with the skill, experience and work ethic of the team; the fact that they arrived early each morning smiling underlined the "Happy Building" epithet; Jarek, the site foreman, had an especially cheery demeanour. The work involved stripping the walls back to bricks, removing walls, reinforcing foundations, plastering, extending the bathroom and removing one bedroom to create a large ensuite bedroom. The latter certainly would not have been done without Valter's vision and patience in explaining how it would look. We were able to deviate from the original plans without any problem which was very important in achieving the final look which we had desired. Valter was very careful in sticking to time and budgets which I had never experienced before with builders. The kitchen, bathroom, two bedrooms, living room and hallways were finished to the highest possible specification within our budget. There were one or two small features which, with hindsight, we would have improved such as door handles and shower fittings, however this was down to us not specifying exactly what we wanted. These are very minor details and a tiny part of the overall picture.

Roofing (Flat)- 9 Nov 2020
Darren & Son (plus Team) responded promptly to our advert for a Roofer in My Builder, they accessed the repair and quoted quickly. The work required was worst than expected but they tackled it with professionalism and speed and kept us informed of the work being done (via photos). They also cleaned up and disposed of all redundant waste. Thank you once again guys for being able to sort out what could have been a potential bigger problem and I would recommend then to anyone.

Extensions- 18 Dec 2019
What a wonderful extension Dan has built for my family and I! Everyone who visits us comments on how lovely it looks - we are extremely happy! From the moment I spoke/met with Dan I knew he would be the builder I would assign for this project. He was friendly, knowledgeable and spent time explaining the work which he would conduct. Dan and his team were always on time and worked hard all day. As promised, Dan completed the job on time and to budget. As with any build, we did encounter some issues, although Dan resolved these without any problems. I would 100% recommend Dan and his team! Give them a try, you'll be pleasantly surprised! Thank you Dan and co.

Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours. Over all I would say they are a team of very nice people, who care about what they do and take pride in achieving the result their clients are after.

What to ask a Surrey extension builder before hiring?

Before hiring an extension builder in Surrey or extension building company in Surrey, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Surrey 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 Surrey 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 Surrey?

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 Surrey 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 Surrey 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.
