"My husband and I had a very pleasant experience with Kenji. He was very responsive and professional. My only complaint had to do with the pressure washing procedure. Water came through the crack under our front door, resulting in damp wood floors on the inside. Our screen door was damaged as well. Plus I was a bit disappointed that the old paint chips were left about the lawn which I had to clean up later. I've yet to see how the Semco product will wear under our Pacific Northwest weather, rain, cold, expansion and contraction. Everything looks good new, the test will be how it looks and wears a year from now and years to come."

"Kenji works very hard to please his customers. He applied a nice coating to our carport concrete floor. It was cracked and discolored before his work and now looks like a car showroom floor. Some chemical was spilled on our aggregrate driveway, causing some discoloration. Kenji power washed and scrubbed the whole driveway, but some discoloration remains.
He also cleaned and applied a colored coating to our stamped concrete patio. This was a bit of a challenge. For some reason, the coating bubbled. Kenji spent a lot of time sanding and refinishing these bubbles. We still have a few, but the overall effect is very pleasing and easy to maintain"

"I found Kenji, the owner (I think) to be easy to talk to about my project. It was complicated because I had concrete floors that had one area that was terribly discolored. He explained to me that he would stain the floors using a blending technique. The result was great. The floors are beautiful. I began this project so my condo would look great for the market. My husband wondered why we hadn't done this before. I guess because we didn't find Kenji. He's great! Nadine J."

"Kenji was amazing. The team was quick, highly skilled, and knew exactly what we wanted in our home. Our new floors look amazing. We had a party planned and they were up against a tight timeline and they made it work. I had compliments all night long on my new floors. I have already referred Kenji out to 5 friends and family members. I plan on having my bathrooms and kitchen counter-tops done soon as well! "

"Kenji is still working on his English so you have to listen closely. However the quality of his work more than compensates for this little bit of extra effort. Beyond that his contract documents are very detailed and crystal clear as to the work to be performed. And the work is excellent, craftsmanship approaching artistry. We Would Most Definitely Recommend Him (and his helper)."

"We couldn't be happier with Kenji and his cement options he gave us. He was on time, gracious with advice and listened to what we wanted. He did a beautiful job and we will definitely be calling on him again to do our front porch when our other remodel projects are finished. No one can tell that our gazebo floor is not slate tile. We love it! To have a custom designed floor for out outdoor entertainment is truly wonderful. Cannot say enough for Home Tech Design and will highly recommend them to anyone."
