This was a wild year! We had a lot of fun and worked our butts off. We had our ups and downs. Our good days and not so terrible days.

We would like to thank all of the people that allow us to work with them in accomplishing their dreams and ideas and look forward to another great years!

Happy New Years to everyone!

Merry Christmas!!

Thank you to all who put together a great Hartford's Hometown Christmas, Hartford SD. We put together a great float with the help of my wife, kids, Ashley, Keke, Jesus and Logan! Special thanks to the Nielson family for walking with us and handing out candy.

We would like to wish all families a Merry Christmas and Happy New Year!

After a long wet July, we were finally able to finish up this pole barn for Watembachs! The weather was not cooperating with us but that didn’t stop us with getting this amazing barn done. Want to thank Long Creek Steel and Hartford Building Center for getting everything out to us. Huge thanks to the Watembach family for getting us out to Emery again! Looking forward to the next project.

Quick update for our new construction! Over the last two months we have had Siemonsma electric, Darrin’s plumbing, new prairie insulation, Irvine Construction LLC, Hartford Building Center, MasterBrand Cabinets, and Carpet One Of Sioux Falls get this house moving along great! All of the guys that help us bring plans to life are the absolute best to work with! Soon we will be tackling the trim! After we clean up the floors can shine again and we can hope to get the Nielson family moved in soon!

We had an absolute blast remodeling Zach and Rachel’s bathroom. We definitely took our time to get it done but we all made it through the process without getting sick of each other. This bathroom will be beautiful for years to come!

Here are some pictures of our progress on Joey and Kelsey’s after a month. Hopefully this week we get the house enclosed and can start working towards getting her sealed up and ready to get finished up this winter! Thank you Hartford Building Center for getting us everything so far!
