“Smooth and professional job. As you can see the job was not easy but his men Rose to the occasion and then professionally installed the leader”
— Donyale McRae
“Johnston did a great job in working on a balcony which had old tile and needed a refresh with the Westcoat tile system. Received a site visit from Jason 24 hours after calling and a quote shortly thereafter. Workers professional, stayed until sunrise, and kept the property clean each day. Would use Johnston again!”
— Harley Johnson
“We give our highest recommendation to C. Johnston and Sons for brownstone exterior and roofing work. Charles and his sons are highly professional, punctual, responsible, and responsive. They made thoughtful suggestions and recommendations, and were very expert in their approach. They did top quality work on our late-1800s brick brownstone, including some difficult façade repair. Just as important, they were pleasant and easy to work with, always on time or early, very responsive to all of our questions and concerns, and actually left their work spaces cleaner than they were to begin with. Their prices also seem quite fair and reasonable. A good experience in every way.
Positive
Responsiveness, Punctuality, Quality, Professionalism, Value”
