Extensions- 16 Nov 2024
Conservatory demolition and new extension built Having experienced several poor builders over the last year, Gavin & his team showed how it should be done. Quoted 6 weeks for the job, they actually finished in 5 weeks! Showed up on time every day, made clear progress daily, and the level of workmanship was second to none. Friendly, polite, clean and professional. This also goes for the external roofers, plasterers and electrician which he used during the job. This is what all builders should be like. Would definitely use them again for other projects and highly recommend them to friends & neighbours.

These guys have just finished up a single storey extension for us. From being extremely punctual and going the extra mile on all areas, they have met all our expectations. They arrived on site and levelled the pour of the foundations, laid the block and beam floor and built the walls up in a great time with a keen eye to detail. They will now be my first recommendation and go to for any future work.

Plastering- 15 Apr 2024
We hired Dean for plastering and tiling our bathroom. Dean came out to review what was required and provided a break down quote quickly. His prices were fair and we appreciated that he was honest in what could and couldn't be done. Throughout the job he was clear on what times and days he could work and was always on time. He cleaned up after himself and never left a mess. The plastering work completed was done quickly and to a high standard, especially impressive when there was a large hole in the bathroom wall from the plaster blowing. We also hired Dean to complete the tiling of metro tiles for us, again the work was completed to a high standard and we are really pleased with the results. The wall (as with all Portsmouth houses) isn't level or straight! We trusted Dean to be left in the house alone and would definitely hire him again.

Fireplaces & Flues- 13 Jul 2024
Dan was fantastic, from first communication to completion. What was a tired old eyesore of an electric fireplace, is now a thing of beauty and really the focal point of the room. Transparent pricing, with careful and thoughtful work carried out. Dan's knowledge and skills made, what could've been a long complicated, messy project, look a quick and easy, which I'm sure (and know it was not). Would recommend in a heartbeat. Top work and can't wait to get a real fire going in there soon.

Bricklaying- 11 Oct 2015
Ray is a polite and respectful character who worked hard completing the work required. His timekeeping was very good, ensuring the work was completed on time. His estimate was accurate and honest. He actually popped back to finish some work - on his own time - to keep the project on track. Ray was also very flexible, and accommodated all my requests. I would recommend his services to others and will certainly use his skills for future projects.

Really pleased with the results and would highly recommend Harvey and his team.

What to ask a Sandown extension builder before hiring?

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

An extension builder in Sandown 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 Sandown 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 Sandown?

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 Sandown 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 Sandown 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.
