Will was helpful and gave me what I thought was a good quote. He was professional throughout. We had the old drive stripped off, new concrete edges around the perimeter and replaced the shingle. I am very happy with the the finished drive it looks great. I would recommend Bly contracting to anyone needed work done in the area.

Loft Conversion- 29 Apr 2023
My house was totally renovated by this company. I was very satisfied with much of the work. I was informed that I would be given the buildings certificate and the electrical certificate for works completed once final payment was received. I was given the buildings certificate. I was not given the electrical certificate, although the house had been fully rewired as part of the work. I chased up for the certificate but my requests were ignored. I was aware an electrician had come to inspect the works, and the builder who had been on site indicated it appeared to go well. I have now just recently had the electricity in the house inspected by an electrician and have found there were issues that required rectifying.

What to ask a Southgate extension builder before hiring?

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

An extension builder in Southgate 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 Southgate 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 Southgate?

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 Southgate 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 Southgate 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.
