Meet the Team

We listen from the start.

We want to learn about you, your lifestyle and your ideas to make sure we're planning the right build for you, down to the smallest detail. We're passionate about fine home renovations that are a direct reflection of your ideas.

We take your lead every step of the way:

planning, design and execution. You can be confident the project will never get away from you. Learn more about our design and build processes.

We hammer out the details first.

We make sure everyone is on the same page with what will unfold in the construction process.

We keep to our schedule.

There are no surprises. You'll have our committed schedule to work from so you always know what is happening and what's next. And good fiscal management of the project means no cost overruns.

We're conscientious.

We understand renovations are a disruption so we'll always make the work area as contained as possible. Our team, including sub-trades, are thoughtful and respectful of your space and schedule.

We're accountable.

You can be confident we're always available to answer any questions and address any concerns you may have.

We won't forget about you.

After the work is done, any new concerns – if any – will be addressed by our dedicated after-sales representative.

Our History

Slotegraaf Construction was started in 1979 by Sweitze Slotegraaf. For 20 years he built a company based on integrity, quality and craftsmanship. Sweitze's son Dave, who grew up working in the business, joined the company full-time in 1996 and together they continue the tradition of building quality custom homes and renovations.

Slotegraaf Construction has grown to include a dedicated team of skilled tradesmen, an in-house Design Consultant, and office administration. Our talented team of trades and professionals are committed to our vision of "Built Right. On Time."
