How do I find a waterproofing or foundation repair company for sale?

Waterproofing and foundation repair firms work below grade, usually on other people’s basements, and most are small, owner-led companies. They are not always easy to spot on a listing site. A seller may call the business a contractor, a home improvement company or a specialty trade. A good search therefore uses several words and several routes at once, and it starts with a clear idea of what you want to own.

Search under the right headings

Try waterproofing, basement repair, foundation repair, drainage and excavation, then browse the general contracting and home services categories. Save the searches so new listings reach you. Read each listing for what the firm actually does. Some do mostly interior drainage, some mostly exterior digging, and some mostly crack repair. Each mix needs different crews and equipment.

Approach owners directly

Many trade owners never list. Suppliers of drainage products, concrete and equipment rental yards know who is busy and who is tiring. A short, courteous note that promises confidentiality is fair. Ask permission to talk before asking for any numbers. Our pages on finding a paving company or a masonry business describe the same approach for neighbouring trades.

First questions to ask

Keep the first conversation about the shape of the firm. These questions tell you quickly whether to go further.

• How many past jobs still carry a warranty, and how are callbacks handled?
• Where do the leads come from, and how much depends on the owner’s own reputation?
• How busy is each season, and what keeps the crews working in the slow months?
• Is the digging done by the firm’s own crews or by subcontractors?
