Kellow Construction helped us out with our recent office TI. They were communicative, timely, kind, and clean. We're very happy with their service and will be calling them again for future work.

The Kellow Construction team is fantastic. Management is professional and amicable, costs are transparent and the finished work is top-notch. I will use them again for another construction project I have in the autumn.

We contracted with Kellow Construction to start a major kitchen/dining renovation the end of April, to be completed the end of August - and it was finished right on time! The permitting and demolition processes were smooth, and soon we were in the exciting construction phase. We were given plenty of time and assistance in making choices and it was fun to watch the transformation take place. Throughout the entire time, every worker was respectful of the fact that we were living in the house. The entire experience was pleasant and we are delighted with the outcome - the vision I had in my head is what we ended up with. Kudos to Kiel and Emily Kellow, Jason Long and the entire team for giving us a fabulous new space!

Kellow Construction is the best of the best! They helped me redesign my primary bath and I couldn’t be happier. They treated me like family and helped make my project better than I could have possibly imaged. I highly recommend!

I cannot recommend Kellow Construction enough! We needed a pole in our living room removed - right before Christmas - eek! Well there was absolutely nothing to worry about. The team that came in was so knowledgeable about the work and even had ways we hadn't thought of to make it better. The guys could not have been more friendly and kind. I truly got the sense that they all really loved what they do and genuinely enjoyed each other. I feel like that came through in the amazing job they did. Not only did they do a fantastic job on the project, they left the house better than they found it. You would never have guessed that we had construction done - it was spotless. Kiel always answered any questions that we had thoroughly and thoughtfully, always including both my husband and me in the process. And to top it off, he is just a sincerely great guy and a pleasure to talk to. It is rare to have work done without any hassles or stress but I've never even heard of anyone actually enjoying the process, but that is exactly what you'll get with Kellow Construction. We can't wait to have them back for more projects!
