Crawl Space Repair Services for a Safer, Healthier Home

Crawl space damage doesn’t stay hidden for long. It shows up in musty air, soft floors, high humidity, and mold that spreads through your home. If ignored, it can lead to serious structural problems and expensive repairs down the line.

At Force Basements, we repair, encapsulate, and insulate crawl spaces to stop moisture at the source and restore strength where it’s needed most. We also offer financing, because every homeowner deserves a dry, stable, and healthy home, regardless of budget.

Why Crawl Space Problems Shouldn’t Be Ignored

In Central Illinois, many homes are built over vented crawl spaces. These structures pull in moisture, cold air, and pests when left unsealed. Over time, this hidden damage rises into your living space and affects your comfort, safety, and energy costs.

Common warning signs include:

  •  

  1. Sagging or uneven floors – caused by moisture-damaged joists that can lead to full structural failure

  2. Musty odors and high humidity – signs of mold growth and poor air circulation affecting your home’s air quality

  3. Mold growth and wood rot – weaken beams, floorboards, and support posts over time

  4. Cold floors and drafts – increase energy bills and make the home uncomfortable year-round

  5. Insect infestations, including termites – thrive in damp crawl spaces and can spread unseen

  6. Cracked or shifting support beams – reduce structural stability and increase the cost of future repairs

Even if your crawl space looks fine now, these problems can develop quietly and worsen over time. That’s why early repairs and full encapsulations matter. It’s not just to protect your home, but to restore its value and livability.

Common Crawl Space Issues We Fix

Standing Water or High Humidity

Moisture buildup promotes mold growth and weakens wood framing.

Sagging Floors Above the Crawl Space

Over time, inadequate support can lead to floor joist movement and deflection.

Musty Smells Indoors

Often caused by poor air circulation in damp crawl spaces.

Mold, Rot, and Mildew

These biological growths can spread into your home’s air system and cause health issues.

Poor Insulation or Energy Loss

An unsealed crawl space allows cold air in during winter and traps humidity in summer.

Our Complete Crawl Space Repair Services

Crawl Space Encapsulation

We install high-strength vapor barriers to fully encapsulate your crawl space, turning it into a clean, dry, and conditioned zone. This helps reduce humidity.

Crawl Space Waterproofing

Our interior drainage systems collect and redirect groundwater before it can pool under your home causing musty odors and mold growth.

Crawl Space Dehumidifiers

We install high-performance crawl space dehumidifiers that maintain healthy moisture levels year-round. These systems are energy-efficient and built for tight spaces.

Sagging Floor Repair

If your floors feel soft or uneven, the issue may be beneath your feet. We install steel crawl space support jacks and stabilizers that lift and support beams, restoring structural integrity.

Crawl Space Insulation

We offer closed-cell spray foam and other crawl space insulation options that keep your floors warmer in the winter, cooler in the summer, and reduce your utility costs.

Crawl space encapsulation is the process of sealing your crawl space with a thick vapor barrier to block moisture, pests, and outside air. In Central Illinois, where humidity and rain can cause serious moisture problems, encapsulation is one of the best ways to protect your foundation and improve air quality.

Yes. Moisture in your crawl space can lead to:

  1. Mold and mildew that spread to the rest of your home
  2. Structural damage from rotting joists and beams
  3. Pest infestations
  4. Allergies or respiratory issues from poor indoor air quality

Stopping moisture at its source is key to long-term home health.

Absolutely. If your floors feel bouncy, uneven, or soft, the problem is often related to weakened or undersupported beams in the crawl space. Our crawl space stabilizers and support jacks can lift and reinforce these areas to restore stability and prevent further damage.

The cost varies depending on the problem and the size of your crawl space. Minor repairs may cost a few hundred dollars, while full encapsulation or structural repairs may be in the thousands. We provide free inspections and detailed quotes with no pressure or obligation.

Most crawl space repair projects can be completed in 1–3 days, depending on the size of your crawl space and the complexity of the work. We always aim to finish on schedule and leave the space clean and safe.
