What our clients are saying about working with SL Custom Home Builders...

"Thank you for everything that you did to make our remodeling project such a success. We can't say enough good things about the quality of work and remarkable craftsmanship. The transformation from the 'before' to the 'after' is amazing... We LOVE IT! Jack, you went above and beyond to make sure that things went smoothly, making the entire process much easier and more enjoyable. Along the way, a friendship developed that we hope can continue for many years to come. After all, there are plenty of IPAs to be shared on our beautiful new porch and deck! Please extend our gratitude to the entire SL Custom Homes team. They all played a role in building a place where we look forward to creating many great memories. Special thanks to Sly for his incredible work on the cabinets, finishing work, etc. His talents are a focal point in our new place, and we continue to be in awe of his handiwork. Thanks again, it was a pleasure working together!" - Mike and Penny Sutkay

Dear Jack , "We cannot thank-you and your craftsmen enough for a spectacular, superb, impressive, outstanding, excellent job, better than well done, it is very well done. Martha and I are very happy with our new windows as it is better than expected in all areas. It is worth much more than just a simple 'thanks Jack have a nice day'. I was thoroughly impressed with the exterior finish trim work as I grew up with knowing only brick mold. This wood-looking iron clad aluminum appearance is by far an outstanding choice. Looks great. I also stopped by Argonne Lumber and thanked Ernie for all of his expertise and much needed assistance in our window project. In this make a buck greedy world, words cannot express the gratitude and character of true caring and honest people such as Ernie and yourself, Jack. Doing business with honest to goodness, truthful, professional companies such as Argonne Lumber and SL Custom Home Builders is very 'priceless'. Martha and I are very pleased. Thank you, Jack Diermeier! Sincerely, Terry and Martha Pederson

I am holding off on a porch for now, but will not hesitate to call you again. And, frankly, I regret not having you build the house. Your project management, professionalism (and jumping in to help even during a packer game) and the professionalism of your workers and subcontractors was a breath of fresh air.. Again, thank you! I look forward to working with you in the future and hope you and your family have a nice summer. Regards, Mary
