Extensions- 16 Oct 2023
Mariusz & his team are amazing, from start to finish they have been fantastic & we cannot recommend them enough. We met with a couple of builders for quotes & felt like our project would be in good hands with Mariusz, we instantly liked him & had a good feeling. He was happy to talk through everything with us, answer our questions & nothing was a concern or a problem, this continued throughout our whole project. Communication was faultless throughout, which in our past experience is unheard of & Mariusz was on site multiple times a week. The team were polite, hard working, tidy & professional. Andrew & Pavel were the main guys on our build & they were amazing. They arrived the same time every morning & worked so hard 6 days a week. We cannot believe how quickly & professionally they carried out each stage of the build, which ensured all timelines were met. There was no cutting corners, the quality of work was excellent, with many of our neighbours coming over to comment on their craftmanship, especially the brick work. Our local council building inspector assigned to our project was satisfied & complimentary of the build throughout, no concerns were raised. Doing any size home renovation project & finding someone you can trust & rely on can be daunting. However, Mariusz & his guys really are who you hope to work with. If you are looking for a team then look no further, you will be in safe hands. It's been an amazing journey & a pleasure to work with Mariusz. Thank you

What to ask a Dorking extension builder before hiring?

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

An extension builder in Dorking 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 Dorking 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 Dorking?

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 Dorking 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 Dorking 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.
