Les McDougall – Residential and commercial foundation expert

Owner Les McDougall started his business in 1983 as a licensed bricklayer and stonemason, specialising in construction services and the rectification and repairs of federation buildings and dwellings. Over the next 10 years, Les became an expert in residential and commercial foundation repairs and underpinning buildings.

In 1993, Les became a licensed underpinner and has successfully completed thousands of foundation construction and remediation projects, as well as underpinning for the domestic and commercial sector, insurance companies and the Department of Fair Trading.

With over 38 years’ experience in the building and construction industry, Les prides himself on providing cost effective solutions to his customers without compromise. This is why he only uses solid concrete for repairing and laying foundations and piers, because he knows concrete works!

Why Hire Adept Underpinners?

Over the years, Les has developed a reputation not only for creative construction solutions, but also for excellence through both professional standards of service and quality workmanship. Clear communication is an important part of his work ethic and has a lot to do with his company’s outstanding record for completing on time and within budget.

Another important part of Les’s success in repairing residential and commercial construction and excavation problems is ensuring that his clients fully understand the work that needs to be undertaken. He appreciates the inconvenience often associated with having tradesmen working on-site, so he does his best to guarantee a stress free experience during the project.

On-site cleanliness is another important aspect of Les’s work ethic and is regularly commented on in their customer testimonials. The endorsements and recommendations received from previous clients and engineers are also testimony to his belief that a quality experience is important for his clients.
