Over 20 years of experience doing home maintenance. My specialities include: painting, woodwork, demolition and general home repairs. I work with every customer to ensure they are satisfied with every job!

"Overall, careless and sloppy. He had one guy that was dependable but he was constantly pulled to work at other locations. As result, my projects were put on hold. Mike tried to complete the jobs himself but simply made things worse. Had to find someone else to the job and clean up his mess. Not worth hiring. Do yourself a favor, save time and money and find someone else."

"While he was here putting my 4-poster bed together, I fell and broke my foot when he said he was finished. My neighbor had a run inside and looked at it, and it looked like a bed. No issues. I later went in, and the bed is not solidly put together. It is shaking, and he also scratches the hell out of my newly done wooden floors. I have called him three times and texted him three times, and he said Send me your address again, and I will be there by the end of the day, three weeks and two days today, and he has done nothing, and I'm done. I just put in a complaint with Angie's List updated 12/11/2025 See last review he reuses to come back and fix the bed correctly and repair scratched floor?..Angi?s list has closed the case?.unreal!

"The HVAC in our new home has been problematic since day one until finally the heat pump quit. We called Airtech and they came in and identified the problem. Basically we had an over powered system with too many zones for the square footage and size of ductwork in the home. They installed a new heat pump, removed our electric backup heat and zones then coupled our heat pump to propane heat as the back up. Works like a champ now! Knowledgeable and easy to deal with."
