Extension Builder in Petersfield
I’ve been around the building trade for most of my life. My dad was a builder, and when I was four he built the family home we lived in during the 1980s. I spent a lot of time on site watching the trades, learning the craft, and developing a passion for quality workmanship. After leaving school I worked for my dad’s company for three years before taking a break from the industry. I returned at 27, helping with projects my dad had won, quickly taking the lead on jobs and eventually setting up my own company in 2001. I ran multiple projects at once, earning a reputation for reliable, high-quality work. In the last four years, I’ve been working for a local small building company, gaining further experience on a variety of projects. After recharging during the pandemic, I’m now ready to help clients again with both small and larger jobs, always delivering quality work, clear communication, and a job done properly.

Restoration & Refurbishment- 11 Sep 2022
My partner and I couldn't be more thrilled with the service and standard of workmanship that Matt and his team have achieved on our recent first floor conversion. The quality of the finish is fantastic and I would have no hesitation in recommending him to family and friends. Throughout the whole build communication was brilliant and at no point did Matt or Tony ever assume or make any decisions without consultation or checking in. Problems and solutions were worked through jointly and nothing was every to much trouble especially as the scope of what we originally asked for grew as the build went on. This was driven by us adding items to the original brief. They were really helpful with recommending showrooms and suppliers which made the decision making process streamlined. We were lucky to move out for the build but everyday our home was kept clean and tidy. Finally all snagging has been dealt with promptly and it's lovely to see that the company is also striving for a high standard of finish. Thanks very much for everything.

Plastering- 15 Apr 2024
We hired Dean for plastering and tiling our bathroom. Dean came out to review what was required and provided a break down quote quickly. His prices were fair and we appreciated that he was honest in what could and couldn't be done. Throughout the job he was clear on what times and days he could work and was always on time. He cleaned up after himself and never left a mess. The plastering work completed was done quickly and to a high standard, especially impressive when there was a large hole in the bathroom wall from the plaster blowing. We also hired Dean to complete the tiling of metro tiles for us, again the work was completed to a high standard and we are really pleased with the results. The wall (as with all Portsmouth houses) isn't level or straight! We trusted Dean to be left in the house alone and would definitely hire him again.

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

An extension builder in Petersfield 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 Petersfield 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 Petersfield?

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 Petersfield 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 Petersfield 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.
