Company Profile
Founded in 1974 and led by president DeAnna Helfer, P&A Drywall Supply, Inc. is a leading independent distributor of gypsum wallboard and framing materials in the St. Louis area. We operate two branches in Pagedale/Overland and Wentzville.

Verified contractor accounts only. Ratings audited quarterly.
“We shifted our custom residential framing packages to P&A Drywall Supply, Inc. last season. Their takeoff estimators are meticulous—they spotted a load-bearing transfer discrepancy in our drawings that would have cost us thousands in framing corrections. Elite service.”
“Their crane truck operators are the best in the business. Staged three heavy framing drops on a steep, narrow hillside lot with zero damage to the trees or neighbor's fence. Very dependable logistics dispatch.”
“Top-notch independent supplier counter. They don't just scan tags—they actually understand engineered wood and local code requirements. Whenever I call, I get direct answers on dispatch times and pricing buffers.”
