Slotegraaf is amazing! I hired them to do a large renovation on a 1926 house. Right from the beginning I felt they would do a great job. They set me up with wonderful designers who brought my ideas to life, including adding some of their own. They started the project on time, and the quality of their work was fantastic. Everyone comments on how beautiful the house looks. They made the Reno run smoothly and as stress free as possible. Slotegraaf is the only company I would hire if I had to renovate again!

During a basement renovation, my wife and I noticed that 2 of our foundation walls had a 1 inch crack all throughout. We called Slotegraaf and the owner Dave came out to see it personally! Not many companies have the owner hands on! He was so professional, looked at the problem, came up with a solution on site and put the wheels in motion. Had to put my house on stilts, knock out my cinderblock foundation and formed and poured a new concrete foundation with updated egress windows. They were super busy, but he fit us in because this was a serious issue for our home. Can't say enough good things

As a local designer, I work with a lot of builders and contractors, and I have to say that Slotegraaf is among the best! I've worked with them on multiple projects and they are always extremely professional, highly-qualified, and provide great quality work. My designs can be complicated and unique to build, but they always put the time into understanding the design and take the details seriously.

Their project management is also something that sets them apart, everything is well coordinated so nothing gets overlooked. They also handle tough time constraints and always do their best to get things
