Customer Reviews
"Erdman Construction did my garage door and garage side door casing. They did a fabulous job, however, their pricing is too rich for my blood to get many more projects done."
"We love our deck. Nick was great as well as everyone that built our deck. On time, great work and great clean up. We would certainly use them again."
"We 100% recommend Nick Boyer and Chad Carlton from Erdman Construction!! Nick Boyer and Chad Carlton from Erdman Contruction originally came to our home to help us with the bathroom floor. However, due to other construction problems done by another company, they need to wait until the other company comes in and fixes everything that needs to be done. This other company kinda left us hanging and running with our money. Nick and Chad both did not leave us hanging! They were very professional, honest, kind, caring, and made sure we were okay before they left. They gave us really good advice, called some people that could help us get on a great new path, and restored our faith that there are still really good and decent people out there with such kind hearts! This is by far the best $300 consulation fee we have ever spent. You two went above and beyond for us and we just met you!! We will be calling you when all of this is taken cared of for any and all future work that needs done on our home. Thank you from the bottom of our hearts for everything you are doing for us. We greatly appreicate it and appreicate you both as well!! You have no idea how much this truly means to my husband and I. We are so grateful!"
