I contracted with R&K to install additional blown-in insulation in my attic. Our salesperson, Luis M. was extremely knowledgeable, professional and personable. He listened to our concerns, evaluated the situation and suggested that we add enough additional insulation to attain an R-49 rating. Their pricing was competitive and their service was exceptional. The 2 man installation crew that arrived at our home were very polite and professional. They showed up exactly on time and completed the job in a timely fashion. They thoroughly cleaned up after the job and left our home as they found it. The new insulation has made a noticeable difference to our comfort level in our home. Thanks to R&K for a job well done.
