 Trustindex verifies that the original source of the review is Google. My husband and I have hired Koch Konstruction many times, including replacing home roof twice, replacing shed roof, installing storm door, and miscellaneous home repair work on soffitts, etc.  We have always been pleased with the work they've done for us.  It has been a pleasure doing business with Paul, the owner.  He takes time to come to the home and explain details and answer questions.  Brandy, the lady who answers company phone, is always very cordial and helpful.  We highly recommend Koch Konstruction.

Charge was reasonable and the repairs occurred before the interior experienced the additional damage. Recommended without reservation.

I had storm damage with shingles blown off and when they came out to tarp it I told them I had shingles left over and he said he could fix the roof immediately and I didn't even have to go through insurance after all. He was soaked to the bone since it had been raining and I really appreciated the work he did.

 Trustindex verifies that the original source of the review is Google. We had Koch Konstruction repair both our siding and roof, and they also removed a door and balcony from our bedroom. From start to finish, the communication was excellent, so we always knew what to expect. The crew was professional, kept the job site clean, and the quality of their work was outstanding. Overall, it was a fantastic experience.

Had a roof leak pop up at my personal house and knew exactly who to contact! Paul is super responsive. He was out quickly to assess, quote, and once approved, schedule. The repair was completed quickly and there has been no issues since! Would 110% trust Koch with any project for work or home!

 Trustindex verifies that the original source of the review is Google. We had a great experience working with Paul at Koch Konstruction for our new siding, windows, and doors. Paul was professional, knowledgeable, and easy to work with from start to finish. When unexpected issues came up, the team worked through them efficiently, and Paul was always available to talk, answer questions, and provide updates. The quality of the workmanship was excellent, and the crew was respectful of our home. Everything looks amazing, and our home feels more comfortable and updated. We highly recommend Paul and Koch Konstruction!
