Extensions- 17 Jun 2022
Hartwell Projects came in to complete our extension. Right from the quoting process Jonathan was polite, timely and very knowledgeable. As our first building experience we knew very little about what needed to happen - Jonathan was patient, calm and answered all our questions and spent a lot of time on site with us making sure we were happy with everything. Jonathan was also transparent at all times willingly offering different solutions which ranged in prices to try to accommodate and make sure we made the best choices for us. When the build started we were amazed at just how clean the site was left everyday, and the progress and speed at which the build happened. Jonathan has a great core team working for him and each and every person was polite and so hardworking, which sums up Hartwell projects really well in our eyes. Attention to detail was always on point and each team member was happy to stop and talk to us when we returned home from work. The site was left secure each night without fail if we had to work late. During the build there were times that certain things weren’t going as smoothly (as with all projects there’s the odd surprise) but the speed of Jonathan’s reaction was fantastic and was quickly sorted, at all hours of the day Jonathon was available to answer any questions or worries. We wouldn’t hesitate to recommend Hartwell Projects for any project, if we ever need any future work doing Jonathan will be our first contact. ⭐️ 5 Star Service ⭐️

Greg and Amy, we can’t praise them highly enough. They have just replaced a roof lantern for us with a flat unit. They were polite, prompt and very friendly, couldn’t fault their work and left everything clean and tidy. We would definitely recommend them and certainly use them again. Many thanks.

Liam was very easy to work with and provided a competitive quote with clear end point after a site visit. The job involved stud lining and insulating a 12 x 8m agricultural building, creating a partition wall to divide the space, installing a small internal work room and installing doors. Liam and his team worked quickly and to a high standard to complete the job on time. Following this work we hired Liam to install worktops and storage units all made to our requirements and specifications.

I would not hesitate to recommend White & I construction LTD to anyone who is considering building an extension or making internal modifications. The job was completed as required and although we were abroad at the time, Ivan ensured excellent communication including photos and videos at each stage of the project. All issues were dealt with quickly and each stage of the project was completed to the required timeline. On completion of the project snags identified were rectified immediately to our satisfaction. I would like to use this opportunity to thank Ivan and his team for a job well done. Dave & Kathleen Frankland

Nice enough people to work with but the driveway hasn’t stood the test of time. A rather rough surface began breaking up a few months after completion and they agreed to come back and add a further top coat of Tarmac. After multiple broken promises, I asked for a firm date - since which all is silence. Not recommended

What to ask a Bournemouth extension builder before hiring?

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

An extension builder in Bournemouth 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 Bournemouth 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 Bournemouth?

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 Bournemouth 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 Bournemouth 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.
