"I have requested couple of different quotes to replace the roof on my garage. I decided to go with Infinity Exteriors. Logan Rezash worked with me who gave me the best deal. He was very professional and easy to talk to and explained in full details what they will provide me with my project. The materials and the warranty on the project that works for my budget. They kept me informed of the status of the project from the start to the finish. Their team that worked on the job was very polite and fast. They did an excellent job. They cleaned the yard and twice doubled checked for any loose nails around the garage. If you have a project to be done, I would recommend Infinity for your project. Dragica Miladinovic"

"I regret hiring this company. The sales rep was pushy and misleading about what was included ? I believed gutters, soffit, and fascia were part of the job, but later was told it was just a cleaning (which never happened). The crew left open holes in my roof on day one, and the ?one-day job? dragged into four days of loud, late work with sloppy cleanup and debris left behind. When they said the job was done, I found exposed nail heads, poor trim work, and granule loss on my brand-new roof. They had to send crews back multiple times, and I still had to hire two independent inspectors at my own expense. I was also charged over $1,000 extra for wood and for trim I didn?t want ? now I?ll have to pay to remove and replace it. Despite repeated promises from management that they would ?take care of me,? my calls, emails, texts, and photos went ignored after one brief call from the GM. Poor workmanship, poor communication, and no accountability. I would not recommend this company."

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. In 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. Today 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. J & K Home Improvement offers the highest quality materials available and backs our workmanship with a ten year limited warranty.

"Simply put, you will NOT find a better, more honest, more helpful, more easy-to-work-with, reasonably priced contractor than John Lee and his crew at J & K Home Improvement & Restoration! We had a "complicated" set of circumstances when our home was damaged by a storm, last winter. The insurance company sent out an estimator to assess the damage and, after the company recommended J & K Home Improvement & Restoration, I was introduced to John Lee. I eventually learned that John also does estimates for a variety of insurance companies (because his company is so well regarded), and he patiently listened as I described the nuances associated with our house. During our initial consultation, he was able to clearly describe all of the steps that would be necessary and answer all of our questions. Long story short, not only was John able to address EVERY single concern and request that we had regarding the eventual repairs to the house (including roof, siding, and a window upgrade that would have cost much more if we had done it at a later time), but he spent plenty of extra time making sure that everything we had talked about was addressed to our 100% satisfaction! He was also able to persuade the insurance company to cover more complete repairs than was originally specified by the first adjuster! In addition, when we had an electrical "hiccup" associated with all the pounding on the walls, John quickly sent an expert electrician to locate and correct the problem. He absolutely could have passed those charges on to us because the failure wasn't due to any mistake on the part of his crew but, instead, he picked up the unanticipated expense himself. It was truly a pleasure to work with John! He made a difficult situation as easy to manage as possible, and we would strongly recommend J & K Home Improvement & Restoration to anyone who wants to hire a quality contractor that stands behind their work and well-earned reputation!"

"I had just purchased a house. They came out and put white sealant on my flat roof. I have had water in my house for the past 7 months and hired a new roofer and they fixed it the right way and told me they basically did nothing with the white sealant. "
