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.

Bricklaying- 10 Jun 2020
We hired Jamie to take out a window and install a door. He was very polite, gave a good quote and timescales etc. He understood exactly what we wanted, visited a few times before starting to ensure measurements were exact and that small details that we requested were agreed and clear. Before he started we asked him to quote for another job and he completed both within the timescales given, plus he was clear about what would happen on what day, and stuck to it. Nothing was too much trouble, he is very courteous, his workforce too. He's understanding, responsive to contact, and an excellent job done as well as being very clean and tidy. We are already looking to have him do the next works we need to get in the pipeline! We would not hesitate to recommend him.

What to ask a Hampshire extension builder before hiring?

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

An extension builder in Hampshire 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 Hampshire 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 Hampshire?

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 Hampshire 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 Hampshire 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.
