Crawl Space Services
Your crawl space is a vital, yet often overlooked, part of your home's health and efficiency. It significantly impacts your indoor air quality, energy bills, and structural integrity. At Lake Atitlan Insulation, we offer a full suite of specialized crawl space services to ensure your home remains a safe, clean, comfortable, and efficient space. We invite you to explore our services below.
Crawl space encapsulation
Crawl spaces are susceptible to moisture and humidity, which can lead to serious issues like wood rot, fungal growth, and even foundation cracks. Our professional crawl space encapsulation service provides a robust solution. We completely seal the area with a durable, white vapor barrier, covering 100% of the ground surface.
This process also includes the installation of a dehumidifier and a sump pump to actively reduce moisture buildup. By fully sealing all seams and junctions, we prevent mold growth, improve air quality, lower energy bills, protect your home from the elements, and prevent costly repairs from water damage.
Crawl space repair
Your crawl space is critical to your home's structure – it houses essential plumbing and, in some cases, HVAC systems. Damage in this area, such as wood rot, fungal growth, or foundation cracks, can lead to expensive repairs and reduced indoor air quality. We provide comprehensive, customized solutions to assess and address the root cause of the damage.
Whether you need structural repairs like band sill, joist, girder, or subfloor replacement, our expert team is ready to restore your crawl space. Signs of Crawl Space Problems include standing water, mold or mildew growth, sagging or rotted joists, and cracks along the crawl space walls.
Crawl space waterproofing
Water and humidity intrusion can cause significant damage to your home's structure and even impact the health of occupants, leading to toxic mold and compromised indoor air quality. We expertly identify the source of water and humidity, implementing customized solutions. This might include installing French drains, a sump pump, a dehumidifier, and full encapsulation.
Crawl space Water Intrusion
When water is allowed to accumulate, it can cause problems to the structure of the building. We solve standing water in your crawlspace by Installing a system of French drains, constructed out of pipe and gravel, which pitch to the lowest point where a sump pump collects the water and then pumps it out an exit line. We're skilled in evaluating various factors like your foundation type, water source, and soil grading to provide honest, effective solutions that work for your home.
Crawl space humidity control
Dampness, moldy closets, or musty odors are often a sign of crawl space moisture, as up to half your home's air can come from this area. As warm air rises, it pulls the air upward and creates a suction, drawing air from the lower extremities of the house. We eliminate humidity by sealing vents and outside air, and installing a vapor barrier with taped seams. We also maintain consistent temperature and relative humidity with a Aprilaire dehumidifier.
Crawl space mold remediation
Fungal growth under your home can be a serious health concern. Our team rapidly addresses this by removing old insulation where mold is suspected or confirmed. We then meticulously spray all affected areas with a hydrogen peroxide-based chemical and wipe them down during our full remediation application.
Crawl space cleanout & rodent control
Unwelcome guests like mice can wreak havoc in your crawl space. If you're hearing scratching, seeing droppings, or noticing strange odors, contact Lake Atitlan Insulation for a full inspection. We specialize in rodent exclusion, one of the most effective long-term methods to eliminate and prevent future infestations. This involves sealing entry points (around utility pipes, windows, and doors), eliminating Food & Water Sources, and Reducing Nesting Areas (prevent rodents from nesting in walls, boxes, or other spaces).
