What customers say

Bradley and Ricky Viles

This contractor did the general contracting putting in our new manufactured home, he was honest and helped us hurry up the job and genuinely cared about our situation. He also had a lot of knowledge he shared when it came to the permits and he was HONEST when it came to the money, which I’ll be forever grateful for! Our home turned out great, we had a few bumps in the road but they were never really due to our general contractor, he’s a great guy and has great sub contractor connections! I would post pictures but unfortunately my phone doesn’t allow me, so my husband also will be leaving a review with a before and after photo!
