Exterior Waterproofing & Drainage in Trumbull county, Ohio
What exterior waterproofing involves
Exterior waterproofing stops water before it reaches your foundation wall. A crew excavates down to the footing, cleans and repairs the wall, applies a membrane or coating, and sets drainage tile in gravel at the footing. Many jobs also add a dimpled drainage board, new downspout extensions, and regrading so surface water runs away from the house.
In Trumbull County, heavy clay soil and freeze-thaw cycles hold water against block and poured walls. That makes drainage as important as the coating itself.
What to look for
- A written scope that names the membrane product, the drain tile type, and where the tile discharges (daylight, sump, or storm connection).
- A clear plan for the dig: utilities, landscaping, decks, and concrete that must be removed and restored.
- A transferable warranty that covers labor as well as materials.
- A look at gutters, grading, and window wells, not just the wall.

Common questions about exterior waterproofing & drainage
- How much does exterior waterproofing cost?
- Full excavation and waterproofing typically runs about $70 to $150 per linear foot, so a whole basement often lands between $8,000 and $25,000. Deep walls, hard access, or needing to remove decks and patios push it higher. Partial or single-wall jobs and drainage-only fixes cost less.
- How often does exterior waterproofing need to be done?
- Done correctly, the membrane and drain tile should last decades, and many contractors offer 25-year or lifetime warranties. Clogged or crushed tile, or downspouts that dump near the wall, can cause problems sooner. Clean gutters yearly and check discharge points.
- What should I expect during the work?
- Expect a trench dug along the foundation, often 5 to 8 feet deep, with heavy equipment in the yard. The job commonly takes several days to a week or two, depending on wall length and weather. Backfilling and final landscaping may be separate steps.
- How do I judge a contractor's quality?
- Ask for a detailed written scope, proof of insurance, local references, and the exact warranty terms. Be cautious of quotes that skip drain tile or say only 'sealant'. Quotes that differ widely usually differ in scope, so compare line by line.
