Replacement of a conservatory for a larger more eco friendly and useable space to comprise a kitchen, dining and family room. Shea and his excellent team completed the work to a very high standard and I am very happy with the result. In addition he was charming, friendly and efficient as were his colleagues in the trades who completed their various roles in a friendly manner and with an obvious level of expertise and pride in their work. I plan to have Shea and Mountfair Homes back again for my next round of home improvements and cannot speak highly enough of them.

Landscaping- 2 Aug 2020
I am really happy with my front garden, it now looks completely in keeping with the period and has transformed the look of the whole terrace. Peter really understood what I wanted, and had a huge amount of knowledge of the type of renovation and the difference it could make by using stone of the period, together with the right kind of flag stones to help reflect light into the front of the house. I cannot believe the difference it has made to the front of my house. I would absolutely recommend Peter and would not hesitate to use him again.

What to ask a Sunderland extension builder before hiring?

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

An extension builder in Sunderland 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 Sunderland 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 Sunderland?

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 Sunderland 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 Sunderland 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.
