Serving Kerrville, TX and surrounding areas. (830) 488-9157
Ground moisture does not stay in the crawl space - it moves up into your floors, insulation, and air. We seal it off completely so your home stays dry and comfortable all year.
Vapor barrier installation in Kerrville means laying heavy-duty plastic sheeting across the entire crawl space floor, sealing every seam, and anchoring the edges to the foundation walls - most standard homes are completed in a single day with no disruption to daily life.
The job sounds simple, but the difference between a well-done installation and a poor one comes down to coverage and sealing. Gaps near pipes, loose edges, and untaped seams defeat the whole purpose - ground moisture finds its way through any opening. We cover every square foot of soil, including around posts and piers, and we send you photos when we are done so you can see exactly what was installed. If your crawl space needs both moisture and thermal protection, combining this with a crawl space vapor barrier system and insulation delivers full coverage in a single visit.
If your Kerrville home is more than 30 years old and has never had the crawl space inspected, an on-site assessment is the right first step - we can tell you exactly what is down there and what it would take to fix it before any money changes hands. You can also reach us directly at (830) 488-9157.
If your house develops a damp, basement-like odor during Kerrville's hot months, that smell is often coming from your crawl space. It is a sign that ground moisture is moving upward into your living area. This is one of the most common early warnings Hill Country homeowners describe before discovering they have no vapor barrier, or one that has failed.
Wood flooring absorbs moisture from below just as readily as it does from above. If sections of your floor feel spongy underfoot, or if the edges of planks are starting to curl or separate, excess crawl space moisture is a likely cause. In Kerrville's climate, this kind of damage tends to worsen each summer if the underlying moisture source is not addressed.
If you have ever looked into your crawl space and noticed water droplets forming on metal pipes or HVAC ducts, that is a clear sign the humidity down there is too high. Condensation means the air in your crawl space is holding more moisture than it should - and that moisture is looking for somewhere to go, which is usually up into your home.
Many Kerrville homes built before the 1990s were constructed with little or no crawl space moisture protection. If you have lived in your home for years and never had anyone look under the house, there is a reasonable chance the situation down there has changed - barriers degrade, shift, or were never installed properly to begin with. A quick inspection can tell you exactly where things stand.
We install vapor barriers in crawl spaces using heavy-duty polyethylene sheeting - typically 12 to 20 mil thickness for durability under foot traffic and temperature swings. Every installation covers the full ground surface, overlaps seams by at least a foot, tapes every joint, and runs the material up and anchors it to the foundation walls. The crawl space vapor barrier approach is our most common service, but we also handle slab-adjacent situations and full encapsulations where a tighter seal is needed.
When we assess your crawl space, we also note any conditions that would benefit from attic air sealing above - because a home that is leaking air at the top and moisture at the bottom is working twice as hard as it should. We will let you know what we find and quote each item separately so you can decide what to tackle now and what can wait.
Best for most Kerrville homes - heavy-duty sheeting laid over the entire crawl space floor, seamed, taped, and wall-anchored in a single day.
For crawl spaces with old torn material, insulation scraps, or minor moisture buildup that needs to be cleared before the new sheeting goes down.
Suited for homes where an existing barrier has torn, shifted, or degraded to the point where sections of soil are no longer covered - we remove and replace completely.
For homes with more significant moisture exposure, we can combine heavy-duty barrier installation with wall coverage and conditioning for complete crawl space control.
Kerrville sits on the Edwards Plateau, where shallow limestone and clay-heavy soil create moisture conditions that most homeowners underestimate. The clay absorbs water during rain and releases it slowly, meaning the ground under your home can stay damp for weeks after a storm has passed. Kerrville summers regularly reach the mid-90s, and when warm, humid soil air meets the cooled air inside your home, moisture migrates upward - right through an unprotected crawl space floor. The U.S. Department of Energy describes this process as vapor diffusion - moisture moving from wetter areas toward drier ones, which in summer means it heads straight into your home. Homeowners in Comfort and the surrounding Hill Country communities face the same conditions and benefit from the same solution.
Kerrville also sits in the Guadalupe River watershed, and the Hill Country is well known for flash flooding events that saturate the ground quickly - even for homes that are not in an official flood zone. A significant portion of Kerrville's housing stock dates from the 1960s through the 1980s, when crawl space moisture protection was minimal or nonexistent by today's standards. In areas like Ingram, where older ranch-style homes sit on lots with heavy clay, a vapor barrier is often the single most impactful improvement a homeowner can make to their home's long-term condition. The Building Science Corporation has documented how incomplete or absent ground barriers lead to persistent humidity problems in homes like these - and the repairs that follow are always more expensive than prevention.
We ask about your home's age, whether you have a crawl space or slab foundation, and any symptoms you have noticed. You do not need to know the answers to everything - just describe what you have seen or smelled. We reply within one business day.
We schedule a time to come out, access the crawl space, and spend time checking the size of the space, the condition of any existing barrier, clearance height, and drainage conditions. You get a written estimate that specifies the thickness of the material and the exact area to be covered before we leave.
The crew lays the barrier across the entire crawl space floor, overlaps and tapes every seam, and runs the material up the foundation walls to secure it. Most installations are complete in a single day. You can stay home or leave - the work is entirely under the house.
We walk you through what was done - with photos if you want them - and remove all debris and old materials from your property. We will note any additional issues we spotted during the job and explain whether they need attention now or can wait.
Free on-site assessment. Written quote before any work starts. No pressure to move forward.
(830) 488-9157We take photos of the completed crawl space and walk you through them before we leave. You should be able to see that every inch of soil is covered and every seam is taped - and we make sure you can. Most homeowners do not want to crawl under the house themselves, so the photos are our way of showing our work.
Anchoring a vapor barrier to limestone block walls requires different techniques and fasteners than standard wood framing. We have worked on older Kerrville homes where crawl space walls are entirely limestone, and we know how to do the anchoring correctly so edges do not lift over time.
We assess your crawl space and give you a written quote before scheduling any installation work. If we find that the existing barrier is still serviceable, we will tell you that too. Our reputation in the Kerrville area depends on giving homeowners accurate information, not on selling work that does not need to be done.
Texas requires insulation contractors to hold a valid license from the Texas Department of Licensing and Regulation. You can verify our standing before you hire. Licensing means you have a clear, official path to resolution if you ever have a concern about the work.
We have worked in Kerrville and the surrounding Hill Country communities long enough to know the local soil, the local housing stock, and the specific moisture problems that older homes here tend to develop. That local knowledge is what separates a contractor who understands your situation from one who is just going through the motions.
