Recently we moved our mobile home onto a private piece of land. We hired McConkey Construction as our General Contractor to handle a lot of the site work.  Because we are from out of State, we needed a company we could trust in getting the work done correctly.  The Company’s knowledge and professional crew solved problems that arise. The Company provided the test pit, septic design and installation, driveway excavation and cement slab. The crew worked well with other contractors on the job. We were very pleased with McConkey Construction Company and appreciate all the work the crew put into our project. This company went above and beyond to get this done for us.   Thanks again for all your hard work.
