Kitchen Fitting- 7 Jun 2021
Didn't turn up …. Nothing against Alan at all … he was very friendly, discussed the works and came across like a good honest chap But … he came to view the works but would not commit to a price. I appreciate there are some unknowns but given he had visited the house for 45 minutes to see what was needed I would assume he would be able to quote a price. He talked about if's, buts and maybe's which I was happy to allow for but this did feel like he was pricing for the 'worst case scenario'. I sent a further note around the tasks and anticipated timings, which he was happy with but it was frustrating that I only found out he was not coming on the day he was due. He was a good guy but disappointed he didn't turn up to complete the work, which was pretty simple around repairing cupboards, replacing shower tray (and cubicle if needed), repairing skirting & floor board).. After he didn't arrive, I asked him if he wanted to complete the work but he has not yet replied....

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.
