"This company was fantastic. They were very meticulous with everything that they did. They replaced our front and back steps with new steps, added a nice railing for the front, leveled existing areas of our patio pavers and sealed everything. They charged much less than any other company for the work they did. I would hire them again for any type of work that they do."

"Overall, this was an extremely positive experience. I'm a graphic designer and I am very detail-oriented. In other words, I'm not the easiest person to please, but I have to admit I am so impressed with our new walkway. It's really beautiful! We get compliments from our neighbors, as well as complete strangers all the time. The process started in early August 2017 when TJ came out to meet with me. I showed him a rough drawing of what my husband and I had in mind. He liked our ideas and offered some really good suggestions. He emailed his estimate about 2 days later, then I went out to his Euclid showroom to look at colors and patterns of pavers. The young man there was helpful and answered all of my questions. Soon after, we settled on a design, style and color, and TJ made us feel confident in our choices. About 2-1/2 weeks later, his crew came out to put in the new walkway. The guys arrived early, they were courteous and always professional. David (I believe was his name) completed the majority of the work. He was fast yet meticulous. I really admired his craftsmanship. He cleaned up while he worked and at the end of each day. The project was completed in about a day and a half. The estimate was accurate. We are very thankful for our new walkway which is the focal point of our new front yard landscaping."

"We hired Koontz Construction to replace the front stoop of our 1920’s Cleveland Heights house. Our stoop was larger and more complex compared to those on most other homes in the Heights and the job was made even more complicated because we wanted to incorporate into the top some granite slabs that match granite I’ve installed on a side porch and the rear entrance to the house. Koontz did a beautiful job; they weren’t fazed by our unusual and very detailed requirements for how various elements of the stoop, like the mortar and the pattern of the brick, should look (in part to match the rest of the house) and they did much more work on constructing the foundation and interior structure of the stoop than I had expected. This included pouring a foundation under the entire structure, not just under the walls which I noticed another company doing a few houses down from us while Koontz was working on our project. The crew was courteous and professional throughout and the owner was meticulous in his craftsmanship and kept us well-informed of their work schedule. On top of all of this, their price was slightly lower than two competing bids I had solicited. As ‘icing on the cake’, while they were working on our stoop, I asked if they might also replace several sections of badly heaved (due to tree roots) front sidewalk. They agreed to add this to the scope of the project for an additional $1100, about half the price I was quoted last year for this same work. It was, of course, more cost-effective for Koontz Construction because they were already involved in concrete work at the house, but they did an excellent job on the sidewalk, too, elegantly curving it around a large tree to minimize damage and perfectly matching the finish to the remaining sidewalk slabs. I highly recommend Koontz Construction!"

"After reviewing the problem, the owner offered a series of possible solutions. He worked with me to put together a plan that included sealing a 9’ length of the outer wall, replacing damaged foundation drain pipes, cleaning out blocked drain pipes to the street, and diverting roof rain water to the street drains. This solution avoided letting water enter our basement and diverted yard water away from our home. It worked well (our basement is now dry) and was somewhat less costly than other company proposals. After the work was done, though, I had to personally extend two drain pipes an additional foot or so to the ditch. The workers worked hard and were very courteous. I would call this company if needed in the future."
