Foundation type
Foundation size
Type of damage/repair needed
Type of issue that’s causing the damage
Foundation Size
Foundation size directly impacts the cost of fixing it. The larger the home, the larger, heavier, and more structurally complex the foundation tends to be. Large foundations also often require more equipment and materials for repairs.
The per-square-foot cost of foundation repairs ranges between $3 and $11 per square foot on average. The range accounts for everything from minor sealant upgrades to full epoxy replacement. Prices can go much higher per square foot for certain materials, but assume this range on average when considering the full area of your home's foundation.

Foundation Type
Your options for foundation repairs will vary based on your home’s foundation type, whether it’s a basement, a concrete slab, cinder blocks, bricks, or a crawl space. Prices for each foundation type also depend on the type and extent of damage since there’s no single solution for all foundation problems.
Due to the extreme humidity in Portland, OR, foundations must prioritize ventilation and moisture resistance. Most Portland homes rely on concrete or stone basements, followed by cinderblock foundations, full slabs, and crawl spaces.
| Type of Foundation | Average Cost to Repair | Pros | Cons |
|---|---|---|---|
| Crawl Space | $3–$12 per sq. ft. | Affordable and easy to build | Vulnerable to mold and rot |
| Concrete Basement | $8–$14 per sq. ft. | Moisture-resistant with proper waterproofing; provides additional living and storage space | More expensive, higher maintenance |
| Stone Basement | $3–$8 per sq. ft. | Designed to allow water in, more resistant to moisture and humidity | Often requires sump pumps or dehumidifiers to keep dry. |
| Cinderblock | $250–$25,000 | More affordable than a slab or concrete basement; more flexibility | Structural repair can be extremely costly |
| Slabs | $3–$11 per sq. ft. | Low maintenance, dries quickly | Hard to access; no room for uility lines |
Type of Repair
The cost of foundation repair can depend on the repair method used to fix your problem. Many types of foundation repair are available, each requiring specific materials and experience. You can hire a foundation repair pro near you to fix most issues.

| Mold Remediation | $17–$34 per sq. ft. |
Type of Issue
Every foundation problem has a unique price tag, particularly when a contractor has to take multiple approaches to fixing it. Foundation crack repair costs, for example, depend on whether the problem stems from drainage problems, soil instability, or poor installation.
Leaks may require contractors to add a range of waterproofing methods to your foundation or investigate the source of the water from inside or outside your home. In more extreme cases, a bowing wall or sinking foundation will require major reinforcement or even replacement.
| Type of Issue | Average Cost |
|---|---|
| Cracking | $300–$2,000 |
| Bowing | $5,000–$7,000 |
| Leaking | $2,000–$5,000 (excluding water damage restoration cost) |
| Sinking | $350–$3,000 |
Foundation Repair Pro Costs
Foundation repair contractors in Portland, OR charge $100 to $300 per hour with materials included. There is a separate cost of $22 to $36 per sq. ft. for waterproofing. Minor foundation repairs in Portland do not require a permit. However, structural repairs, such as fixing bowing walls or replacing damaged cinder blocks, would require city approval.
Due to Portland's high precipitation, your foundation also requires effective drainage. If you need to install a French drain around your foundation to protect it from water damage, be prepared to pay an average of $25 per linear foot. If you need a home inspector, set aside $300 to $500 to cover inspection costs.
Does Foundation Repair Affect Home Value?
Many homeowner may be concerned that visible repairs can damage their home’s value. But that is merely a common misunderstanding. In fact, a home inspection would reveal any underlying foundation damage, and failure to address these issues can sometimes cause a deal to fall through. Therefore, while foundation repair doesn’t have any direct impact on your property’s value, leaving known problems unaddressed would likely make it harder to sell your home at your desired price.
