Founded in 1996, J & K has held quality workmanship at its core from the very beginning. We started as a exterior restoration company with 5 employees. We were small, but we knew that if we worked hard and stayed true to our quality we would be successful in the long run.\n\nIn 2005, responding to huge demand, we started working as a General Contractor. The dedication to quality, strong work ethic and great customer service continued to be our hallmark. Over the years we have grown and learned to never forget the ethics that have guided us.\n\nToday we find the marketplace more competitive than ever before. The rapidly rising cost of materials, fuel and labor make surviving in our industry more and more difficult. Unfortunately the result is a high failure rate of businesses in our market.\n\nJ & K Home Improvement offers the highest quality materials available and backs our workmanship with a ten year limited warranty.
