Our apologies

Things like meticulous planning, responsive client care, and detailed project management may not make for the most entertaining read, but it is what makes Slotegraaf exceptionally capable at delivering construction excellence – on budget and on schedule. But then, there's a lot on the line when it comes to your home, so we think you may find a new appreciation for our kind of company.

The No Surprises Guarantee

We are committed to making your building experience an enjoyable one. Of course, that means delivering on the space of your dreams, but it also means making the process a smooth one, without any of those unexpected bumps that bring stress into your already busy lives.

Our mission is to build and renovate homes right, without surprises, excuses or stress – to make the entire process an enjoyable experience for our customers.
Our vision for homeowners is to be happy with the entire home building or renovation process. For our industry, we see this building a higher overall standard in customer service.

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 continued the tradition. In 2013, Dave took over the business from his dad and is as committed as ever to upholding those foundational Slotegraaf values for the future.

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."
