Crawl Space Solutions

Get better air flow, increase efficiency, and moisture protection

As much as half of the air in your home comes from your crawl space. This means if your crawl space is vented or unsealed, it's likely that the air in your living space has mold, dust, contaminants, and excess moisture that's made its way up from the crawl space. Invest in your health, safety, and comfort with a crawl space system that's proven to provide years of worry-free performance and protection.

The crawl space underneath your home or business is a crucial but often-overlooked area that plays a huge role in the overall air quality and energy usage throughout the structure. McCall Service crawl space solutions are designed specifically to protect your property from moisture damage, providing a cleaner and more energy-efficient space while simultaneously helping deter many pests that seek out moisture-rich environments to infest.

damage to crawl space caused by moisture issues

Signs of a crawl space problem:

  • Musty odors and poor indoor air quality
  • Feeling of dampness in the living area
  • Buckled hardwood floors
  • Mold growth
  • Allergic reaction and worsened asthma symptoms
  • Wood rot
  • Increased energy usage and bills
  • Pest infestations

At McCall, we agree with the building science experts, create a well-sealed, unventilated crawlspace or “closed crawl space” by sealing and insulating the foundation walls and crawl space floors rather than insulating the sub-floor with ineffective fiberglass batts. This is referred to as an encapsulated crawl space. By encapsulating your crawl space, it now becomes a clean and healthy part of your house or building envelope. Call McCall for a free inspection and a free estimate on your crawl space needs.

How McCall Crawl Space Solutions Work

All three of the McCall Crawl Space Solution service package options cover the installation of a vapor barrier system in the crawl space of your home or business, with processes including:

  • On-site installation preparation involving the removal of all cellulose debris and any stored articles from the crawl space. ***Additional fees may apply
  • Installation of reinforced wall liner around the interior perimeter of the foundation wall and support piers using wall attachment tape.
  • Installation of reinforced floor liner over the entire surface area of the crawl space floor and sealing the vapor barrier with seam weld tape.
  • Cleaning of the vapor barrier or encapsulation system upon installation completion.
  • If elected for an additional fee, a cleaning treatment will be performed for all organic material within the crawl space, such as wooden structural components, to minimize the existing mold growth presence prior to encapsulation.

Both the McCall Advantage Crawl Space Solution and Premier Crawl Space Solution packages also come with the installation of a Santa Fe dehumidifier and additional equipment (as necessary). The Santa Fe Dehumidifiers have a 6-year manufacturer’s warranty. Santa Fe Dehumidifiers exceed the Energy Star efficiency requirements, utilize MERV-13 filters to provide superior air filtration, are engineered for low temperature operation and air flow issues that crawl spaces present, provide ducting options for divided crawl spaces, and feature auto-restart in the event of a power outage.

The manufacturer of our materials, Crawlspace, Inc., pioneered crawl space encapsulation in the southeast and is a national leader in crawl space encapsulation and vapor barrier innovation. Their patented vapor barrier system enables fast, flawless installation for permanent home protection. The Your Crawlspace vapor barrier system was designed to resolve efficiency, health, and safety issues for homeowners. Unlike competitors, Your Crawlspace never endangers the home’s foundation wall and is compatible with rigid board, spray foam, and fiberglass insulation applications. The safest and strongest crawl space solution available anywhere.

The McCall Advantage

McCall Service is a local, family, and veteran-owned business that has been servicing Florida and Georgia home and business-owners with safe and affordable pest control solutions since 1928. We are committed to excellence in all that we do, and we believe in delivering incredible value to our customers. When you sign on for crawl space treatment through McCall, you’ll be getting:

Better Service: Our trained and knowledgeable technicians have collectively completed hundreds of vapor barrier encapsulation services, ensuring the perfect solution to your property’s unique challenges.   

Better Materials: All floor and wall liners we use are toxin-free, flexible, waterproof, antimicrobial, puncture-resistant, fire-resistant, and ultraviolet light-tolerant. Materials emit no toxic fumes or chemicals and are strong enough to walk, work, or crawl on. The 15 mm floor liner used in the McCall Advantage Services is stronger than the 20mm floor liners used by our competition due to tighter reinforcing fibers (100% reinforced). The McCall Premier Service boasts a patented and market-leading 36 mm floor liner with a felt bottom, which wicks moisture to a sump pump or low point, eliminating odor buildup over time. 

Safe, Non-Intrusive Installation: Each of our Crawl Space Solution packages are completed using low VOC (volatile organic compounds) adhesive instead of nail guns, which can damage foundation walls or mortar joint. The materials and practices utilized will not interfere with past or future WDO inspections.

The McCall Warranty

The McCall Advantage Crawlspace Solution service package includes a limited 30-year warranty. This warranty is subject to an annual fee which must be paid in full and on-time every year in order to maintain the warranty. The annual fee includes an inspection and cleaning of or replacement of filters on dehumidifiers and sump pumps, if any, as well as repairs to any damaged liner. The warranty is transferable in the event the property is sold.
