Waste Clearance- 25 Oct 2016
What a fantastic professional company! So glad I chose them. I wanted a concrete slab removed from my garden. Their quote came quickly and the price was reasonable for the work involved, which included removal of all debris. When I phoned to arrange a start date, I was fortunate that some of their workmen were in my area; about to finish another job, and so they were able to fit in mine immediately! The three workers were extremely hard working, polite and efficient. When the job was finished I was contacted to ensure that I was totally satisfied; which I was - I have no hesitation in recommending Spaw Construction. I would definitely use them again.

What to ask a Southampton extension builder before hiring?

What qualifications and experience do you have as an extension builder in Southampton?

An extension builder in Southampton 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 Southampton 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 Southampton?

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 Southampton 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 Southampton 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.
