We had a very complicated problem in Jan 2026 with windows that were deteriorating. Karl Kardel Co. managed to restore the windows WITHOUT having to get on the delicate slate roof, which would have had to involve removing slate and installing roof jacks! They also picked a gorgeous green that we’ll be choosing for every piece of trim around the house. MAJOR THANKS, guys!!!

“Karl and his team completed an extensive repair project at my Upper Rockridge home in May 2012. I highly recommend the company and would use him again for a repair or remodel. We had water intrusion problems. Karl was the fourth contractor who looked at the problem; the first three were stumped and could not determine the source.”

“I hired Karl Kardel Company to paint the trim on my house. It was badly in need of repairs and they did a more than perfect job, milling new window frame pieces and repairing dry rot. They even found holes and cracks in the stucco by the chimney and near the roof that needed repairs that I would haven’t noticed myself.”

“I’ve had Karl and his crews help me out on my house on many occasions. From painting to waterproofing work he and his guys are some of the best in the business, and certainly some of the most knowledgeable. If you have a difficult waterproofing issue or stucco building I would not hesitate to call Kardel.”

“We are happy to provide a good reference for Karl Kardel Company. We think you folks did a fantastic job on our house.”
