Bricklaying- 26 May 2026
Jake and Liam came to build a supporting wall in my garden, unfortunately for them, during the hottest May bank holiday on record. However, despite it being a million degrees, they never complained, slowed down or made a mistake. The wall looks amazing. Thoroughly recommend.

Landscaping- 4 Nov 2024
The gardens are looking tidy and it’s so nice to come home to calm and order! Max was very helpful with advice both prior and during the job and very responsive to messages to clarify and answer questions. The quote was competitive and Max was even willing to do a little extra at request, again for very fair cost. End result looks good and hopefully when we can walk on the grass (once it takes root) it will be nice and even - finally!

For anyone looking for someone who can trim and fit oak doors to a very high standard, Tom is your guy. We were in a bit of a hurry and he was able to fit us in, carrying out the job quickly and efficiently, with no mess left behind. Despite our Victorian door frames, Tom trimmed and fitted the doors perfectly, and at a very reasonable price. We would definitely recommend him to anyone looking for quality door-fitting work!!

What to ask a Seaford extension builder before hiring?

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

An extension builder in Seaford 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 Seaford 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 Seaford?

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 Seaford 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 Seaford 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.
