Extensions- 17 Jul 2025
We initially contacted Scott for a quote to build a front porch. At the beginning, communication was clear and helpful, which gave us confidence to proceed with additional work. Scott and his team started several jobs including building the porch, decorating the lounge, refurbishing the ground floor shower, touching up the kitchen floor, changing the wall tiles in the first-floor bathroom, and plumbing/fitting a jacuzzi bath. Unfortunately, the experience changed significantly during the project. The work was left incomplete and Scott stopped responding to our calls and messages before the agreed work was finished. Despite multiple attempts to contact him and arrange completion of the remaining work, we have received no response. While the initial communication and some of the work carried out were positive, leaving a project unfinished and ignoring the client is extremely disappointing and unprofessional. Based on our experience, we cannot recommend this builder.

Extensions- 14 Jun 2018
Andy Slimm agreed to build our retirement house. Unfortunately, six months later our dream has turned into a nightmare. For the early part of the build he was helpful and wanted to do a good job. He promised much and we trusted him with everything. When he went over the deadline he started to cut corners and build 'off plan’ in order to save money and try and finish. Suddenly, the day after we had parted with most of the final payment; he took his men off site without warning and abandoned us. We had to carry on renting as the house was unliveable. Three months later we have had to move into our unfinished home which is deemed “unsafe“ due to the mistakes that have been made. Multiple roof leaks, damaging the interior, creating damp and mould problems. Unfinished roof, drainage. Sewage smells in the house due to an unvented toilet system.2 metre deep/2 metre wide hole at the back of the house full of water, unfenced and uncovered. Building control have asked for his structural calculations where he did not build to architect's plans. We have requested many times that he come back, rectify/finish the work and provide the structural engineer's calculations. He refuses, so no other option but to use other builders and to sue Andy for damages. Such a sad and disastrous end to our dream. We have never written a negative review before, however, we feel strongly that we need to warn others as we do not want other clients to go through the traumatic time we have.

What to ask a Cranbrook extension builder before hiring?

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

An extension builder in Cranbrook 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 Cranbrook 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 Cranbrook?

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 Cranbrook 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 Cranbrook 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.
