Extensions- 7 Sep 2018
Steve has now done two jobs for me: knocked down an internal wall and built a garage. I have just booked him to rebuild two chimneys because the quality of his work is so good. All the guys he hires are hard working, nice and respectful. Nothing is too much trouble. Steve’s communication is excellent, so is his time keeping and he’s a really nice guy. (My friend thinks he looks like David Beckham). As a woman home owner I appreciated being treated with respect and listened to when I wanted to change things. I’d recommend Steve without any hesitation and would suggest booking him soon because he’s going to get booked up.

Extensions- 9 Jan 2024
I would recommend Paul Hamblin of Artisan (south) Ltd without any hesitation. Paul and his team gave first class service from day one until the day of completion. Paul was always easy to reach, quick to respond and reassure. He was also flexible and able to accommodate necessary changes. There was additional work which wasn’t on the original build but Paul’s fantastic team were still able to bring it in on time. Paul’s team, Matt, Daryl and Toby were a pleasure to have around. They were always polite and respectful. Nothing was too much trouble. They left my property clean and tidy. I couldn’t believe how quickly they cleared everything up. They are a credit to their profession. To choose Paul Hamblin of Artisan (south) Ltd is to know that your property is in safe capable hands. Thank you Paul.

Extensions- 30 Jul 2022
Overall hard work to get a decent job done if you question there progress your told it’s your fault.the extension we had done should have taken 6-7 weeks but after 12 weeks we were forced to give them a date to finish job or leave the site. The actual shell went up nice and quickly with no problem. ,it was getting the other trades done was the problem the interior ,roof ,windows etc ,they don’t have those tradesman at hand. Also after the shell was done ,we were getting told someone would be on site at a certain time to later receive text messages to cancel it. Overall we were averaging one and a half days work done in a week. Would I use again? If it was a brick I’d job then yes more than that. NO

What to ask a Weymouth extension builder before hiring?

Before hiring an extension builder in Weymouth or extension building company in Weymouth, 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 Weymouth?

An extension builder in Weymouth 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 Weymouth 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 Weymouth?

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 Weymouth 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 Weymouth 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.
