Ralph and team did a tremendous job on multiple projects on our farmhouse in Hart, MI. Their…read morequality, honesty, and commitment to detail has been a terrific - especially in an rural area that can be challenging to find and schedule resources for the renovation work that was needed. An added plus was put ability to coordinate the project work from remote locations and working through phone, email, and other technologies to keep on track. They were able to stay committed and adjust the work to our schedules and budget planning, which was a huge help. These project have been over a period of two years (again, due to our schedules) after the initial structural stabilization work was done by a previous contractor; this team came in and took over the remaining work and completed * removal and replacement of fencing the original four acre lot * brush and small tree removal * grading pasture for future gardens and planting * lawn cutting through three seasons * removal of dilapidated outbuildings * application of exterior stone and mortar treatment around base of house * reinforcing structural support for interior walls and ceilings * coordinating insulation * installation of drywall and coordination of resources for taping and finishing, painting * purchase and installation of grade 1 8" spruce wall and ceiling treatment, including trim * coordination of electrical plan and installation * design and coordination of stairway rebuild * coordination with local resources for land overhaul, initial planting, and harvesting of oats on ten acres Future planned projects will include * additional tree removal * redesign and grading for new driveway * landfill and berm creation over old driveway and other areas of the property * stone/wood support wall along 72nd Av * additional fencing removal and installation * decking and other outdoor structures * pool house and landscaping

My 95 year old mom lives on a fixed income, in her own home, which was built in 1936…read more Her kids (including me) have been worried that she needed her electrical updated bc we had no idea if it ever had been. We got 3 estimates from licensed, insured electrical companies in the Muskegon area. The estimates were all fairly similar. BUT Korthase was the only one that was honest in telling us that her current electrical actually looked pretty good (it must have been updated from when the house was built, but we had no way of knowing that) and given that she would not likely be in her home for all that much longer, they said in their assessment, a big upgrade was not necessary. This saved my mom 5k! Apparently, there ARE honest companies and Korthase appears to be one of them.

Jess returned my call promptly and completed the work on time. He exceeded our expectation on the removal of a tree that was ready to topple on our property. He cleaned up and stacked the cut tree that we are keeping for fire wood and piled all the extra brush. He was aware that we needed to keep one area clear for water run off so he hauled the extra to the side for us. Professional and honest. If I need any other work done Jess will be my first call. Thanks for a job well done.

I have another project for another property and they have give a very competitive quote. Because of their quality of work and the time of the year there is a lot demand for their services. The only complaint here is now I have another project for asphalting a driveway on another property and because of their busy schedule they are unable to give a time estimate for them to come out, even if the timeframe is somewhere two months out or more, it doesn't matter to me. After having a conversation with Dan, who is very nice, he explained the dynamics of the business and what factors contribute to not being able to define a time. I still hope to do business with them because of their high reputation even if it means a later time down the road.
