Kenji came when he said he would, charged what he said he would, provided great looking overlay. In fact he did a great job helping me pick out color and style appropriate to my patio. He and his crew lifted and moved huge heavy pots and came back after the job was finished just to put them back in place. I love my new patio.

Kenji not only did a beautiful job on the floor but also offed some good design advice. Kenji, one suggestion. I wish I had removed the base boards before you started. That should have made your job easier and some material stuck to the bottom of the boards making clean a bit more work

Home Tech and Design (Kenji) is excellent to work with -- his bid was competitive, great work ethic and customer service. Shows up when he says he will, communicates effectively - explains the product and process, so you understand exactly what will happen & when. Kenji and his team wrapped up just yesterday -- we love the finished product and they left the site meticulous!! Would highly recommend Kenji and his team!

Kenji was very quick with the original estimate as well as with changes to the estimate as we looked at different options. The quality of his work and the speed in which he was able to start and complete the job shows how professional he is. If I ever need more work done, I'll call him first.

Kenji worked hard to get our job done in a tight time frame. His communication with us was excellent as we planned and executed the project. He can be trusted to do what he says he will do. We love the floor design and color! I only have a few floorboard splatters to clean off.

Kenji worked with us to not only find a product and finish that worked but also a price. The finish of the product was not exactly what we had imagined but that is only due to our not fully understanding the product. It turned out nicely and fulfilled our requirements and Kenji worked hard to ensure we were happy with the final product. Although we have not had need to take him up on this yet, Kenji ensured us that if there were any issues we could call him for assistance or correction. Very professional and very good costumer communication and service. Would hire again.

Kenji turned our 100 year old basement concrete slab into something that is worth having a conversation about. He was responsive during bidding, on time, professional, and willing to rework a few areas that were of concern to us in order to ensure we were satisfied. The floor is unique and makes a statement, and we are very pleased! The PJ's

I am very pleased with the results of the concrete resurfacing project. It was done in a timely manner, and my "new" walkway up to my front door is such an improvement over the stained concrete that was there before. It's like a miracle makeover!

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.
