"I am super appreciative that I found Elias. He really stepped up when a simple project turned into something a lot more complicated. We had some windows that we needed to replace, but in the course of fixing that, we ended up replacing the asbestos siding to our house, which revealed wood-shingled siding that needed to be painstakingly replaced. Elias handled everything for me. He found the right people to help him, kept me informed, and the work is clean and well done. I would definitely use his services in the future. I have since returned to him for various other repairs involving plumbing, electrical, tile work, drywall, and carpentry. Thank you for your services, Elias!"

"Called this company for their $77 dollar, which they advertised with a flyer, for a tune-up and cleaning for my heating system. They are a Hayward company and I was told that our Castro Valley home was not in their service area. I bet if I called to buy a new heater they would be out in a day."

"Tech said that the Freon leaked out and that the compressor burned out because of it. Quoted $4800 to replace compressor and recharge, or $7,000 for a new AC unit. Got a second opinion and hired a handyman. Turns out the breaker was tripped and needed some fiddling with. AC works great now. Can’t believe they were going to lie about what was wrong to replace the whole AC. Just because it was an old unit. Get a second opinion for them if they tell you something similar."
