TK Home Improvement built our ADU with exceptional craftsmanship, seamless project management, and top-quality materials—highly recommend for anyone in Northern Colorado!
I have nothing but wonderful things to say about T.K.Improvements! Ted is very detailed about his work! We had a kitchen and bathroom remodel done and he just did an excellent job! He’s very personable and able to answer any questions you might have!
Fast, quality work with good communication. Arrived at the time he said he would and finished the repairs in a timely manner so the painters could follow as planned. Definitely would recommend as well as hire again if needed.
Ted is a fantastic contractor to rely upon… awesome at organization and time management, high quality work, and no fuss fair all inclusive pricing. He was able to squeeze our repair work in over logical quick sessions so we can move back into our bedroom soon… thank you Ted!
Did a great job at our home with a project we had that was time sensitive. Even worked the 4th July. Very accomodating to our schedule. Would highly recommend!
