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.

Extensions- 2 Jul 2017
I can't recommend Damian enough, from the very first engagement he was extremely knowledgeable and reassuring, very attentive to the requirements and armed with great ideas and suggestions. Damian provided a detailed quote very quickly and also followed up immediately to queries and clarifications. Damian is an excellent and highly experienced all-round builder who can pretty much undertake anything in the building trade and finish it to a very high standard. The job he did for me was the addition of a side extension which had a bedroom with a Velux skylight and a shower room, a full house refurbishment, relocation of the family bathroom, and improvement of the rear garden and front driveway. Damian totally stuck to his budget except for the areas where I changed the specification and asked for extra work or costlier items, or where unexpected items came up like woodworm infestation after the old flooring was lifted. Even with these additional items, Damian's pricing was extremely competitive and pretty much at the cost of the materials or parts required. Damian was completely reliable and his team worked at least 6 days a week, sometimes 7 days, from 8 in the morning or earlier! He was always available and responsive to queries throughout, always taking the time to talk or respond to e-mails and SMS messages, always checking to ensure things were right and that I was happy with the work and progress. In summary, I would not hesitate to recommend him and would use him again.

Rhys and his team were a joy to work with- extremely hard working, pleasant and professional team. Rhys and his team did a full renovation of our house, effectively doubling it in size so this was a major piece of work. The job was completed on time and pretty much on budget as anticipated.

Landscaping- 23 Jan 2025
CNH did a great job on the bridge of our busy church in central Guildford. We had lots of positive feedback from our parishioners and they matched the colour of the resin bonding very well to the aesthetic of the building. The end result was that it looked like it had always been there, apart from the obvious newness of the surfacing.

Carpentry- 22 Mar 2018
Ross and his team did a nice job. I was particularly impressed with the carpentry work, a good finish with a lot of attention to detail, the carpenter was very willing to discuss exactly what was required. Some of the masonry work did require additional correction and had to be pointed out to be fixed. But if I had any complaint it was with relation to some slow communications and removal of waste materials upon completion of the job but overall I would certainly recommend.

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.
