"They also do plumbing. Everything is top notch there too. The first time they came it turned out we had to make an insurance claim before he could make the repair. He waived the inspection fee and we got the insurance claim done. The insurance hired clean up people. What happened was that house has 3 levels and the lowest level is slightly below grade and it requires a sewage ejection pump to get things up to the septic system. The sewage ejection pump failed and there was raw sewage in the basement."

"I'm extremely satisfied with the work that was performed.From the first day that I got in contact with the company,I was assured that everything would be ok.Tom of R & L came to my building and assessed the situation and he immediately began to make calls to get things back in order for me.Because of the fire damage my building and contents were in bad shape.Tom was able to contact my insurance adjuster and before you know it there was all kinds of action going on in my building to get things back in order.I must say that I do now have a very professional and new looking building from the work done by R & L company.Of all the different people that Tom had to come and perform work on my building,they were all professional with very positive attitudes,and I felt comfortable with them being in my building.I will be recommending the services of R & L in the future,they are a great company and I love the work that they did for me.

"Did a great job wit the inspection and I feel a lot more confident about the move. The only downside was he showed up a half hour late. I'm sure it happens from time to time, but it is something to be noted if you are in a time crunch."
