The JJ Builders Difference

Pole Barn

Ready to start your next custom build?

Every custom barndominium, pole barn, and post-frame building we build comes with warranty protection you can read before you sign. JJ Builders stands behind Amish craftsmanship with a 5-year workmanship warranty, a 25-year leak guarantee, and a lifetime structural guarantee when your building is built with Greenpost wraps. Serving homeowners and businesses across Pennsylvania, Maryland, and New Jersey.

Your JJ Builders barndominium or post-frame building includes a 5-year workmanship warranty on materials and labor for the structure we build. Our in-house Amish framing crews stand behind the quality of the work from day one through year five.

We include a 25-year leak guarantee on the weather-tight shell and roof systems we install. If a covered leak develops within that period, we make it right under the terms of your contract.

Choose Greenpost wraps on your post-frame build and your project qualifies for our lifetime structural guarantee. This protects the structural integrity of the wrapped post system for as long as you own the building, per the warranty terms in your agreement.
