Extensions- 29 Dec 2021
Zach and Steve have transformed our house! They worked tirelessly for 3 months to create our new extension from demolition of our garage to putting the final lick of paint on the interior! They are the most reliable tradesmen I’ve ever met, complete dedication to our project, sticking to our budget and always there! They went over and above to ensure that our project was complete in time for Christmas. I would have no hesitation in recommending Zach for any project! He knows everything there is to know about the building trade, he comes with ideas and suggestions, is able to source materials in a time where that’s not as simple as it’s always been and always delivers what he promises. If you’re looking for a reliable builder then Zach is your man! Him and Steve bring positivity and enthusiasm to the project and have been an absolute pleasure to have in our home!! We are so happy with the end product and are already planning more work for them!!

Roofing (Flat)- 12 Oct 2018
Kept in touch by phone and text. Arrived on time to look at the problem and quickly identified the issue. Quote arrived quickly and was similar to others we received. Arrived on day agreed to fix the hole and flashing problem and roof looks alot better above the dormer window and on the sill. Left everything tidy. Have kept details for future jobs. No really heavy rain since fixed but no problems in lighter rain.

What to ask a Swaffham extension builder before hiring?

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

An extension builder in Swaffham 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 Swaffham 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 Swaffham?

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 Swaffham 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 Swaffham 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
