Custom Home Additions & Garages Built for Greensburg Properties
A few things come up again and again on Greensburg jobs: early 1900s brick and stone homes that need a structural check before an addition, and city utilities that have to be located and coordinated before excavation. We plan for both before we price the work, and we know what the local building department wants to see on a permit application, which keeps the review from dragging on.
Common challenges we address here
- Early 1900s brick and stone homes that need a structural check before an addition
- City utilities that have to be located and coordinated before excavation
- Steep grades in the older neighborhoods that affect drainage and site prep
Seasonal Considerations
Greensburg sits a little higher than Pittsburgh and picks up more snow, which pushes some winter exterior work. Spring is the busiest season for home improvement projects in town.

What Greensburg Customers Say
JP Construction built our two-car garage from the ground up and it came out better than we imagined. They pulled all the permits, kept us informed throughout, and finished on schedule. Quality workmanship and zero headaches.
We added a master suite and laundry room to our 1980s colonial. JP Construction matched the roofline and exterior perfectly, and neighbors have asked us if the house was always that size. Their crew was on-site consistently and that level of involvement made all the difference.
Getting permits for our older home was intimidating, but JP Construction navigated the whole process without any delays. The addition came out exactly as designed. Honest pricing, clear communication, real craftsmanship.
