Our Customers are Happy
Great company to work with, Here at ST Evans inc. we us RainTight on all of our projects
ST Evans IncWe could not be happier with our Rain Tight system. Not only is the product top of line and but the company and staff are outstanding.
P BRainTight Decks is a great company to work with. They always provide a high-quality product and communicate very well thought-out the entire process.
Ethan ZachmanWe recently had a roof put on our deck. It looks amazing. Well worth the wait. They are very busy but right on schedule with what they originally told us
Leo LanzafameRaintight installed an under-decking system for us to keep the patio below our deck dry. Tom and his crew did an excellent job. They arrived on time every day and cleaned up at the end of the day. They kept me informed of the progress of the project and explained what they were doing. They showed me how to maintain and clean the system as well. The end result looks great! I was very happy with the sales process as well. This company did an awesome job and Tom and his crew were wonderful.
Alan HeitmanMy under deck is fantastic, they did a really nice job…….. with exception of the lights that are cheap junk. They don’t fit well and fall apart quite easily. They don’t install the lights which may be why they use them (someone else’s problem). They told me that the lights they use are all they can find. Not sure I fully believe that but they really need to upgrade the lights especially for the price they charge for them.
Dennis FischerTom was amazing! He needed to replace what was installed and took the time to do it right! He knew this project meant alot to me and executed it flawlessly.
MelissaThe Rain Tight installation team arrived on time, cleaned up after themselves, and their under deck roof/ceiling looks great.
Mike KarlowI strongly recommend using Rain Tight Decks. They were very easy to work with, great communicators, the quality of work was excellent and competitvely priced. Thanks Anne, Dave and Rick for a great experience.
