Warning Signs You Need Foundation Repair
Contact our foundation repair contractors when you notice these warning signs. Catching small foundation issues early helps prevent them from becoming bigger problems that could permanently damage your house foundation.
Our team has recognized common warning signs of foundation problems you should know about:
Uneven Flooring:
As your foundation shifts in the ground, it can cause your home’s floors to shift too. Your flooring can become uneven and difficult to walk on. If you notice uneven flooring that wasn’t there before, contact our professional foundation repair team.
Exterior Cracks:
Shifting foundations cause floors and walls to move. This results in exterior cracks, interior cracks, and concrete crack repair needs throughout your property.
Rotting Wood:
When your home’s piers and beams show rotting wood, contact our foundation repair service. Rotting wood often signals water damage caused by saturated soil. Saturated soil increases pressure on your house foundation, leading to cracks and foundation failure.

Your home’s foundation is its literal base. When cracks, settling, or shifting occur, the consequences ripple throughout your property. At Foundations First Northwest, we specialize in home foundation repair in Lake Oswego and nearby areas, offering proven solutions that restore strength, safety, and peace of mind.

Why Foundation Repair Matters
Foundations endure tremendous forces: soil pressure, seasonal moisture shifts, seismic activity, and the weight of your home. Over time, these stresses cause common issues like:
- Foundation cracks in walls, floors, or slabs
- Uneven or sagging floors
- Doors and windows that jam or don’t close
- Bowing or leaning walls
- Gaps between walls, ceilings, or floors
- Moisture infiltration near the base
Ignoring these signs leads to costly damage, including structural deterioration, mold growth, or system failure. Prompt foundation repair is critical for preserving your home’s integrity and protecting your investment.

Foundation Repair Solutions We Offer
Depending on your foundation problems, we offer tailored repair solutions:
Foundation Piers and Underpinning Installing steel foundation piers (helical or push piers) beneath the foundation transfers load to more stable soils. This method addresses foundation settlement repair effectively.
Slab Jacking Injecting grout beneath settled concrete slabs restores elevation and support. This concrete repair method fixes sunken floors and walkways.
Foundation Crack Repair Cracks get routed and filled or sealed with epoxy or polyurethane injection. This restores structural continuity and prevents water intrusion for proper foundation waterproofing.
Wall Reinforcement Carbon fiber straps or steel beams stabilize bowing or cracked walls. This prevents further wall movement and structural damage.
Soil Stabilization and Drainage Improving aggressive soils or moisture pressure helps prevent future damage. Proper drainage protects your foundation from water damage repair needs.
Waterproofing and Moisture Control Applying coatings, installing drainage systems, and diverting surface water support lasting repair results. Our basement waterproofing contractor services complement foundation repairs.
Not every home needs every method. As your reliable foundation contractor, we match solutions to conditions—ensuring you don’t pay for unnecessary work.

Professional, timely and willing to share their knowledge and educate me and my clients on their specific issue and affordable options and not try to gouge them just because they have a nice house and a timeline to address the issue. Will definitely use them moving forward. They saved my seller’s thousands of dollars based on another bid we received.
