"The old air conditioner was installed after purchasing new windows. The window company installed it as though it would never be removed. The prior handyman could not remove it after 3 hours of trying. Ivan and his worker removed it in 30 minutes. The entire job was completed in less than 90 minutes."

"Daniel from Silver Hammer Construction did an excellent job. After getting a leaky window following our nasty winter weather, I felt like no one, my HOA or insurance, was being very helpful. Daniel was helpful and reassuring and did excellent and prompt work identifying the problem. It shocked me to be able to work on it the next day. It took two days to complete the repairs, and the work was well done. My window issue has been fixed. I appreciate all the work Daniel did to explain things to me and his quality of work as well. And the service was affordable and didn't break the bank."
