I have been using Cornerstone for a couple of years now. I started off on my primary house with plumber Kiel installing a iron/water filtration for iron in my well. I then had an electrician install additional outlets at my home and a hvac agent service my a/c system. I was talked into buying the service plan by Kiel and I’m so happy I did. I am getting quality work at a discount. Today I have my dad’s rental property getting flipped, because well,it needs to and he can’t do it anymore due to dementia. I hired some contractors to fix up the property (redo floors, tile work, and even install cabinets). One contractor even claimed to be a prior plumber and assured me he could conquer the job with quality. Well…thank goodness Jerry, a Cornerstone plumber, came to my rescue because my so called plumber had no clue what he is doing. Jerry is taking the time to make sure the plumbing is done right and to county code! Going above and beyond the call of duty. Every time I have called cornerstone for electric, plumbing, or HVAC it has always been top notch service. I know you may not be the cheapest, but you definitely get what you pay for! Thank you!
