No matter the size of the job, we take great pride in delivering end-to-end care. From the bid, to the project, to completion, we treat our customers like family.


We thoroughly examine the potential job to make sure we address all visible issues. Once the full scope of the problem has been diagnosed, we’ll walk you through our findings to make sure we’re on the same page.


We specialize in difficult and challenging projects, and take pride in preserving and restoring buildings to their original beauty.


When the job’s done, you won’t even know we were there — we take great care to perfectly match existing materials, such as brick, mortar and stone.

    “If you are looking for a construction company to repair or maintain your old Church building, inside or outside, big or small, please do what we have been doing for 25 years. Call. Sounds like an old advertisement slogan? Wait until you work with them, from planning to every single phase of the project, each person involved in it gave us their best.”
