  • "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! –Seattle WA
  • "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!" -Mercer Island, WA
  • "Kenji did a fantastic job. His knowledge of the product and hard work provided us with unique and lasting floors at a fantastic price. I would highly recommend Home Tech Design & Supply."- Tacoma, WA
  • "Visiting AIA open house we saw the SEMCO floor system applied. We spoke with the owner of the AIA house and he highly recommended Kenji’s company – Secom System Seattle. The company was very professional, on time and worked hard to achieve the color of our choice. Kenji’s service is excellent. There have been some spots we did not like the color of the application, Kenji came and corrected them. We love are floors and are glad we have decided to go with SEMCO flooring (Kenji’s company). Great product, excellent service." - SAMMAMISH WA

  • "The floor looks awesome and we receive many compliments on the final result."- Seattle WA
