Stable Foundations

Stable Foundations repairs foundations, crawl spaces and basements across the Richmond area. Its main office is at 12439 Maple St. in Ashland, with a second office on Summit Avenue in Richmond. Its About page says it began as a small Richmond foundation repair company in 1992, and BBB gives the same start date. BBB names J. A. Walder Jr. as president. The sister company Walder Foundation Products says Jack A. Walder Jr. also leads J.A. Walder Inc., which his father founded in 1957.

Most of the work is structural. The foundation page names helical piers as the fix for stair-step cracks, sticking doors and walls pulling apart outside, and lists crack injection, wall reinforcement and house leveling. Under the house, the company replaces vapor barriers, seals and encapsulates crawl spaces, installs dehumidifiers and sump pumps, and repairs sagging floor joists and failing support posts. It also repairs bowing basement walls and waterproofs basements with interior drains.

Every job starts with an inspection. The foundation page says the company offers a free on-site inspection, with measurements and notes, and gives you a written proposal before you commit. The site says some systems carry manufacturer warranties that may transfer with the house, depending on the product, but it gives no lengths or terms. Ask for the warranty in writing with the proposal.

On licensing, the foundation page says the company is licensed through Virginia DPOR under license 2705140978. The state list shows that number as a Class A license for Stable Foundations LLC with one specialty, Highway/Heavy (H/H). The state rule for H/H lists foundations among the work it covers. The related J A Walder Inc license at the same address adds residential (RBC) and commercial (CBC) building. Hanover County issued Stable Foundations LLC five residential alteration permits between February and May 2026.
