Take a look under a house that has never had a barrier laid down and you'll find soil that is faintly damp no matter the season. That dampness is not sitting still. Ground moisture evaporates continuously into the air beneath your floors, and a crawl space with exposed dirt can release gallons of water vapor into a home every single day without anyone noticing until the damage shows up. A&A Waterproofing performs crawl space vapor barrier installation for homeowners near Marietta, GA, and across the wider metro area, and putting a proper liner between the earth and your house shuts that transfer down.
A&A Waterproofing, owned by Allen Aschwege, is a veteran-owned waterproofing and foundation repair contractor with its base of operations in Marietta, Georgia. Liner work is a service our crews perform on its own and as part of larger sealed systems, and it involves clearing the ground surface, selecting material with the right thickness and puncture resistance, covering the full soil area, running the barrier up the foundation walls and around piers, overlapping and sealing every seam, and mechanically fastening the terminations. All of our work happens on buildings that already exist, never on new construction. Customers include homeowners and commercial property owners across Marietta and the surrounding counties, and quotes are always free.
Homes without adequate ground cover show it in familiar ways. Rusting duct straps and metal connectors, insulation that has fallen out of the joist bays, dark staining across the subfloor, wood that feels damp to the touch, and a humidity reading down there that stays high regardless of weather. Plenty of houses do have a barrier, though it's often a thin sheet that has torn, shifted, and stopped covering much of anything.
Soil holds an enormous amount of water, and it releases that water upward whenever the air above it is drier than the ground below. In a crawl space, the air above the dirt is almost never drier for long, so the process runs continuously and the space stays loaded with humidity. Thin builder-grade sheeting fails within a few years because anyone crawling through tears it, it never got sealed at the seams, and it stops well short of the walls. Uncovered strips along the perimeter let the same amount of vapor through as no barrier at all in some cases.
Doing it correctly starts with preparing the ground. Debris, rocks, and old torn material come out so the new liner sits flat and does not get punctured from underneath. Our crews then roll heavy material across the entire soil surface with generous overlaps at every seam, seal those overlaps with tape rated for the application, wrap and seal around every pier, and run the barrier up the foundation walls before fastening it mechanically near the top. Penetrations for plumbing and posts get detailed individually rather than left open.
Installed this way, the ground stops feeding moisture into the space and the humidity down there drops substantially. Framing dries out, metal components stop corroding, insulation stays in place, and the air being drawn up into your living space is no longer carrying whatever was rising off the dirt. Qualifying installations come with written warranty terms so the work is documented rather than assumed.
The liner does more work than its simple appearance suggests, and these are the returns that come from installing it well.
Covering the full soil area with sealed material cuts off the largest single moisture source under most homes. That reduction happens immediately rather than gradually. Everything else you might do down there works better once this piece is handled.
Thin sheeting tears under the knees of the first person who crawls across it, while heavier reinforced liner holds up to service work, storage, and years of contact. Puncture resistance is the difference between a barrier that lasts and one that becomes confetti. We use material selected for durability rather than whatever costs least per roll.
Overlaps sealed with proper tape, piers wrapped individually, and wall terminations fastened mechanically are what keep a liner functioning as a continuous barrier. Gaps at any of those points let vapor bypass the whole system. Detailing is the least visible and most important part of the job.
Plumbers, electricians, and HVAC technicians do more careful work on a clean, dry surface than in mud. Service calls become shorter and less unpleasant for everyone. Homeowners also gain the ability to go down and look at something themselves without dreading it.
Dehumidifiers, drainage, and sealed vents all perform better once ground vapor has been eliminated, since they're no longer fighting a source that never stops. Starting with the liner keeps other equipment from being oversized to compensate. This is the logical first step in almost every crawl space project.
A liner solves ground vapor and leaves other conditions to address, which these related services cover.
Homes needing more than ground cover benefit from a complete sealed system, and our crawl space encapsulation service adds vent sealing, dehumidification, mold treatment, and full cleanout to the barrier itself. That combination is what produces the noticeable change in air quality upstairs.
Liner cannot manage water that arrives from outside, so properties with standing water or seepage need collection first through our crawl space drainage system installation service. Drain lines and a sump handle the liquid, and the barrier handles the vapor.
All of our work beneath a home sits under crawl space repair and encapsulation, which includes moisture control, fungicide treatment, vent fans, and structural considerations alongside barrier installation. What a property needs comes out of the inspection rather than a package.
Anyone can unroll plastic across dirt, so the value comes from what happens before, during, and around the edges of that.
Rocks, construction debris, and old torn sheeting all come out, and the surface gets leveled where it needs it so the new liner lies flat. Material stretched over sharp debris punctures from below where nobody will ever see it. Preparation determines how long the installation lasts.
Liner that stops two feet short of the perimeter leaves a strip of exposed soil giving off vapor the whole time. Our installations run the material up the foundation walls and fasten it, closing the gap entirely. That perimeter detail is where a surprising number of jobs fall short.
Every support pier gets wrapped and sealed, and openings around plumbing, posts, and ductwork get detailed by hand. These points take time and cannot be rushed with a roller. Skipping them leaves openings scattered throughout an otherwise sound barrier.
Veteran-owned and locally run since 1996, this company has installed liner in crawl spaces across Cobb, Cherokee, Paulding, and the surrounding counties for decades. Being nearby means a warranty question years from now reaches someone who remembers the job.
Getting under the house and quoting the work costs you nothing, and you'll receive options with prices attached rather than a single figure. Acorn Finance is there when a payment plan helps, and veterans, EMTs, firefighters, police officers, and active-duty military save 10% under Hometown Heroes.
Builder-grade sheeting in the six mil range tears almost immediately under any traffic, so we install considerably heavier reinforced material that stands up to crawling, storage, and service work. Thickness alone is not the whole story either, since reinforcement and seam quality affect durability just as much. Allen will show you the material during the estimate.
Plenty of the existing barriers we find are torn, bunched up, or covering only part of the ground, in which case they're doing very little. Others are in reasonable shape and simply need seams sealed or edges extended. We'll tell you honestly which situation you're in rather than automatically quoting a replacement.
Running it up the walls and fastening it near the top closes the perimeter gap that otherwise lets vapor bypass the whole installation. Leaving a strip of bare soil around the edges undermines the coverage across the middle. This detail is one of the clearest differences between a thorough job and a quick one.
Summers here run humid enough that outside air entering a crawl space through open vents condenses on cool surfaces underneath the house, adding to whatever the soil is already releasing. Homes throughout Cobb and Cherokee counties deal with this from roughly May into September. A liner addresses the ground portion, and vent sealing addresses the rest.
Low clearance makes the work slower and harder, though our crews handle tight spaces regularly across older homes in this area. Some situations require additional labor time, and that gets reflected in the estimate up front. Access points occasionally need to be enlarged, and we'll flag that before starting.
