"Mad City was personable and professional with all that needed to be done at my home. Patio door replacement, bedroom window replacement, and shower stall installation. They even hired a subcontractor to repair a hole in the ceiling that was caused by a leaky bathtub. My highest complements!"

"Ridgeline came in and assessed the system and made us aware a cost effective repair was an option. Ted efficiently repaired our furnace and tuned it up. Their replacement cost was the best but we can wait at least a few more years until it's necessary!"
