I would highly recommend Kostoff Construction for home renovations. I called to schedule an estimate on 7/9/25. They were here the next day on time and provided a quote the next day. I needed self leveling concrete poured in my basement and installation of interlocking luxury vinyl tile & baseboards. They completed the self-leveling concrete work on 7/16, arrived on time, and returned the next day to install the flooring and baseboards. I’m very pleased with the work and will use them again in the future!
These are your guys- can’t recommend enough. Reasonable cost, very efficient and got it done quickly and well. Nakota listened to all of our ideas and requests and made every one of them happen. Responsive and communicative. Would highly recommend and would hire these guys in a heartbeat for our next project.

We couldn't be happier with how our new deck turned out! Nakoda and his team were incredibly efficient and professional. I wish I could share a better picture, but we haven’t had a chance to set things up for the warmer weather yet. I would gladly work with Krostoff Company again for future home projects and only wish I had known about them sooner when we needed a kitchen upgrade.
I had old carpet upstairs that I didn’t like. Nakoda and Tyler came over on a Wednesday evening to give me an estimate. They had some samples of vinyl plank flooring that I loved; It’s durable and looks great. The following Monday, I had new floors, and I love them! Nakoda, Tyler, and Chris did a fantastic job. They are professional, efficient, and provide great customer service. I recommend Kostoff Construction to anyone.
The guys did a great job , building a new porch using composite material. They made a porch that is safe and beautiful. I would gladly hire them again! Before and after photos below.
