Konstantin was awesome to work with. He helped us with several projects in our house including hanging garage storage, installing a kitchen fan, and installing new windows/shutters. He was professional, always on time and his work was excellent. Highly recommend him!

Konstantin arrived on-time and completed several small projects in my garage (installing storage rails on the walls and hanging a rackfrom the ceiling for my ladders.) Thanks!

Wonderful experience. Kodak group arrived promptly and got the job done right. I had two small projects- a handrail and some carpentry work but I could tell that he is incredibly knowledgable. I will definitely hire them again!!!!

We can't begin to recommend Kosag Group highly enough. Konstantin came to patch what we thought were just two small holes in our kitchen ceiling. But this job turned out to be way more involved than just patching drywall. He showed us how the leak had actually eroded a support beam that we couldn't see before. He cut and installed a fresh beam, and removed the old one (and a ton of surrounding debris), and then patched the hole. He charged us the same price he quoted us initially, before he understood how much more work it would mean for him. He was professional, knowledgeable, really fast, and an incredible value for the quality of his work.
