Words from the
homeowners we built for.
"Riley and his crew literally saved my house. After moving in it was discovered that the back of the house had rotting floor joists after a deck had been improperly installed decades prior. He was able to support the main floor from the damage caused and restore the structure properly."
"I operate a painting company and have worked with Callaghan Contracting on a number of projects. The communication and project planning they offer is VERY rare in the construction industry. As a sub trade, it is a pleasure to work on their projects."
"We had Callaghan Contracting build a pole barn for us. I can't say enough about how great Riley and his brother Rory are to deal with. Very professional and well organized. They deliver above expectations and on budget and schedule. Highly recommended."
"We just had Callaghan Contracting renovate our two bathrooms. They did a fabulous job. The work was completed on time, the workers protected our stairs from damage as they carried material up and down the stairs."
"I had a very positive experience working with Riley. He's very professional and honest. He was easy to deal with, very reliable, and delivered solid work from start to finish. Communication was smooth the whole way through."
"We contracted Callaghan Contracting in the late fall for an estimate on a new deck. Riley came, measured, took pictures and came up with a design, which we agreed to. Due to winter, we had to wait till spring. They dealt with the City for the permit and delivered a beautiful result."
