Our 4-inch basement drainage systems, backed by a lifetime warranty, effectively channel water away from your home and prevent pooling or flooding. With SwainCo., you'll never worry about drainage issues again.

Our Waterproofing and Foundation Repair Solutions

Crawl Space Repair
In Indiana, homeowners turn to SwainCo. when crawl space issues begin to affect comfort and structural safety. Whether it's persistent dampness, visible mold, or uneven flooring, our specialists diagnose and resolve the root cause using advanced tools and proven repair techniques. We restore compromised wood, seal out moisture, and install modern insulation to return your crawl space to peak condition—supporting the overall integrity of your home.

Crawl Space Waterproofing
Excess moisture beneath your home seriously risks its structure and air quality. SwainCo. combats this with tailored waterproofing systems that combine sump pumps, vapor barriers, and drainage solutions. Our crawl space waterproofing system eliminates standing water and blocks humidity from entering, helping you maintain a healthier, more resilient home.

Mold Remediation
Mold in a crawl space can silently impact indoor air and weaken your home's foundation. SwainCo. applies a methodical three-step process, removing mold colonies and using our exclusive Hydrosafe treatment. This service clears existing contamination and addresses the underlying moisture that feeds it, ensuring safer conditions for your home.

Crawl Space Encapsulation
SwainCo. offers comprehensive encapsulation to fully seal your crawl space from outside moisture and contaminants. We install thick vapor barriers, insulate surfaces, manage drainage, and regulate humidity with top-tier dehumidifiers. The result is a protected subfloor environment that resists mold, pests, and temperature extremes while also improving overall energy efficiency.

Crawl Space Insulation
Insulation beneath your home is key in keeping temperatures stable and energy bills manageable. SwainCo. replaces deteriorating or outdated insulation with modern, moisture-resistant materials that help prevent air leaks and pipe freezing. Our installations provide a stronger barrier between your crawl and living spaces above.

Crawl Space Vapor Barriers
Blocking moisture at the source is one of the best ways to protect your home in the long term. Our vapor barrier installations cover crawl space floors and foundation walls, stopping water vapor from rising through the soil or seeping through porous concrete. These barriers contribute to improved indoor air and can significantly reduce future repair costs tied to moisture damage.

Crawl Space Drainage Systems
Water accumulation in your crawl space is more than an inconvenience—it threatens your foundation. SwainCo. prevents this with custom drainage solutions that include French drains and sump pump systems. Our designs ensure proper water diversion, keeping the area under your home consistently dry and structurally sound.

Crawl Space Dehumidification
Managing humidity is crucial for preventing long-term damage in enclosed crawl spaces. That's why SwainCo. installs AprilAire dehumidifiers—known for their performance and reliability. These units regulate moisture levels, discourage mold, and improve HVAC efficiency by keeping damp air out of circulation.

Exterior Drainage
Standing water outside your home can slowly degrade your yard, foundation, and peace of mind. SwainCo. builds exterior drainage systems tailored to your landscape—whether French drains, trench systems, or surface solutions—each designed to move water away from critical areas and keep your property dry.

Downspout Extensions
Redirecting roof runoff is essential for keeping water from saturating the soil around your foundation. SwainCo. installs underground downspout extensions that safely transport rainwater away from your home's base, minimizing the risks of basement leaks, crawl space dampness, and soil erosion.

Foundation Repair
Structural issues such as wall shifting, floor unevenness, or deep cracks should never be ignored. SwainCo. addresses them with precision-engineered solutions—ranging from bowed wall correction and floor supports to soil stabilization and foundation bracing. Our foundation repairs are built to last and restore your home's structural integrity with confidence.

Foundation Inspections
Routine inspections help spot trouble before it escalates. SwainCo. conducts thorough assessments, checking for cracks, moisture entry, and foundation movement. Each inspection includes a detailed report and expert-backed recommendations to ensure you stay ahead of costly repairs and preserve the safety of your home.

Foundation Crack Repairs
Small foundation cracks can become serious structural and water issues. SwainCo. uses the CrackSeal system—a durable combination of commercial-grade sealants and water redirection techniques—to repair cracks and permanently stop water infiltration in its tracks.

Bowing Wall Repair
The expansive clay soils in Indiana often lead to inward pressure on basement walls, causing them to bow. SwainCo. addresses this with wall anchor systems and steel beam stabilizers that counteract pressure and halt movement. These permanent solutions come with lifetime warranties for added peace of mind.

Structural Repairs
Sagging floors and compromised supports indicate that your home's foundation needs reinforcement. SwainCo. replaces or strengthens failing joists, beams, and supports using materials that resist moisture and last for decades. We also address underlying drainage issues to prevent recurrence and maintain structural stability.

Sump Pump Installation
A sump pump is often the first and most important line of defense against water damage. SwainCo. installs Zoeller sump pumps, engineered for durability in residential and commercial applications. Your home remains protected even during power outages or storms with battery backup options.

Commercial Services
Larger properties require scalable solutions. From multi-unit residential buildings to industrial complexes, we offer commercial-grade crawl space, basement, and foundation repair systems. Services include heavy-duty sump pumps, large-scale encapsulation, and drainage solutions tailored to the complex needs of commercial operations.
