Summit jobs tend to land toward the upper end of published ranges for a few reasons. Finished basements mean more drywall, flooring, and trim to remove and restore before a drain can go in. Rock near the surface on parts of the ridge slows trenching and excavation. Steep lots, retaining walls, stone patios, and mature landscaping make exterior digging harder and add restoration work. A simple gutter and downspout fix, on the other hand, can solve a slope driven leak for very little.
| Job | Typical range | What moves the price |
|---|---|---|
| Interior perimeter drain system | $40 to $120 per linear foot | Length of wall, floor thickness, finished space that must be removed, and number of sump pits |
| Sump pump installation or replacement | $600 to $2,500 | New pit versus existing pit, pump quality, discharge routing, and electrical work |
| Battery backup sump pump | $500 to $2,000 | Battery capacity, pump type, and whether a new pit or plumbing is needed |
| Foundation crack injection | $250 to $1,500 per crack | Crack length, wall thickness, epoxy or polyurethane, and access |
| Exterior excavation and waterproofing | $7,000 to $25,000 or more | Depth to footing, number of walls, rock in the soil, hardscape removal, and landscape restoration |
| Crawl space encapsulation | $5,000 to $15,000 | Square footage, liner thickness, cleanup and mold removal, and dehumidifier choice |
| Basement dehumidifier (installed) | $1,000 to $2,800 | Capacity, ducting, and whether a condensate drain or pump is needed |
| Waterproof wall coating or sealer | $1 to $8 per square foot | Product type and wall prep; best for minor dampness, not active leaks |
These are typical ranges from published cost guides, and your actual price will depend on the inspection and the specific job.
