We hired CL Mummert to complete a 6x10 extension on our deck & install new railings by the steps. They did a fantastic job!
His quote was competitive; he was professional and easy to communicate with. He and his team completed the job in a timely manner and left the job site cleaner than when they arrived.
Our upgraded deck is stunning and well constructed, we are so grateful for their work.
I look forward to working with C L Mummert again in the future.
Highly recommend !!

Great experience from Corey and Bobby installing my exterior doors and windows! They also redid my rear porch roof. As they were working on the porch roof, they discovered there was some damage. Corey called me right away and let me know and he fixed it! 10/10 would recommend. Affordable, timely, neat, and informative! My front door was an odd size. Shorter than most and only 34” wide! Corey was able to refit the framing so I have a standard size door. It’s beautiful! My energy bill also came down after the new windows and doors! Couldn’t be happier!
