Our rapid success can be directly attributed to our answering a dire need for quality kitchen exhaust cleanings that customers can stake their business on. We are so confident in this that we guarantee NFPA 96 Fire Code Standards are met with each cleaning we conduct. We take this a step further than a guarantee, we prove it to our customers with a detailed visual report containing before and after photographs of all areas of the entire system taken during each cleaning in an easy to read format that instils confidence and great peace of mind. The other major proponent to our success is that while maintaining the highest levels of cleanliness, we do it green. We sterilize your entire kitchen exhaust systems with the gentle power of steam and contain the grease runoff on the roof and in the kitchen thereby limiting the contamination of grease into the environment. We have revolutionized the Kitchen Exhaust industry. It is your choice who you decide to work with. We hope you chose us. It will be a pleasure working with Grexen, we Guarantee it!
