Helleman Construction has been serving Peterborough and the Kawartha’s for over 15 years.

As a third-generation carpenter and entrepreneur, it’s easy to see why he chose the profession and truly enjoys his work.

Don holds a Red Seal Certificate of Qualification as a Carpenter, has multiple Ontario Building Code qualifications, is LEED accredited, and has obtained many other industry related certifications.

Primarily focusing the last 15 years on project management and land development, Don has also spent some time on the other side of the counter as a Municipal Building Official. It is this unique work history that has him tapped-in to both sides of the equation when working through the permitting, design, and building process.

Septic Design

Helleman Construction is a qualified Part 8 design firm for Sewage Systems regulated by the Ontario Building Code.



We know how to navigate the municipal permitting process and avoid delays to your building project.

Project Management

We have an extensive background managing construction projects in a range of sectors, with a proven trades network.

Although Don is an Ontario Building Code qualified designer, his specialty is septic design and carrying projects through the full permitting process, rather than building design itself. Helleman Construction works in tandem with talented local designers to generate building designs, and can provide referrals if you are looking specifically for someone to design your structure.
