Callum replaced multiple weather boards on our dormer windows as they were starting to split due to lack of maintenance in previous years. It was a job that required attention to detail and was a challenge due to the dormers being recessed. The quality he delivered was great and 100% on budget and time. He communicated very well from first contact to finish and I would use Callum again in the future.

Extensions- 20 Feb 2021
Very happy with the build. Everything went smoothly, Shaun came to our house to discuss the initial quote. What surprised me was Shaun had a full breakdown quote ready the first time we met, by using the online planning with the required work. The final quote had increased but that was due to us wanting extra items such as exterior light and composite doors plus painting. No hidden or extra charges. Everything went as agreed and on time, although the weather did hold the build back on some days. The only trade that was a letdown was the painter, not by the quality of work but reliability, subcontracted and Shaun was quick to sort the issue out right away. Every trade was on time and did the work as agreed to spec. The level of professionalism is what surprised me the most from each trade. From the men doing the ground work and foundations to the electrician. As the customer myself and my parents were spoken to with respect from all the tradesmen and they took their time to explain when we had questions. Huge thank you to Graham the electrician who advised us on the best positions for the exterior spotlights. There was a delay in getting the completion certificate as our build was completed just before lockdown but we have had everything signed and checked by the council. Overall the porch with wc extension looks even better than we could imagine and I would recommend this company to anyone looking to get the same type of work. Thank you Shaun and everyone at S.ewing.

What to ask a Perth extension builder before hiring?

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

An extension builder in Perth 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 Perth 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 Perth?

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 Perth 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 Perth 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.
