Latest review:
Having just moved into a 3 bedroom house, where one of the bedrooms was far too big for my family's needs, Trevor converted the large bedroom into two smaller ones, thus creating a 4 bedroom home. Everything about the job was undertaken with great care and diligence, the workmanship was of excellent standard, everything was done within the time frame set out and all of my questions and queries were answered in full throughout. Trevor was completely professional throughout the whole process even when I changed my mind about a couple of things.

Extensions- 11 Feb 2022
We had to wait a few months before Rick and Lee could start, as their previous job overran. However, we're so glad we did! From start to finish they were an absolute joy to work with. Nothing was too much trouble for them and they always advised us the best way to go about things. They are a definite credit to the trade. The job is now complete and we're just waiting for the sign off from the Council. We can't recommend Skyline Southern enough. If you find Rick is booked up, that's because he's in high demand, for obvious reasons. My advice is be patient and wait, it will definitely be worth it in the end. Thank you Rick and Lee for a fantastic job!

What to ask a Southsea extension builder before hiring?

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

An extension builder in Southsea 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 Southsea 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 Southsea?

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 Southsea 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 Southsea 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.
