Waterproofing & Crawl Space Repair in Alcoa, TN
Alcoa crawl spaces, from wet ground to tired piers
Alcoa sits right against Maryville, and the city still carries the name of the aluminum company that built it up. McGhee Tyson Airport is here too, so a lot of our Alcoa calls come from people who moved in for work and bought a house without ever having looked under it. That's fine. That's what the free estimate is for. We crawl the whole space, photograph the ground, the piers, the vents and the ductwork, and walk you through the pictures at the kitchen table. Water problems, structural support, vapor barrier and encapsulation all come from our crew, so the price you get covers the whole crawl space.

Ground conditions
Alcoa sits in the Valley and Ridge, on limestone bedrock full of sinkholes, springs and solution channels.
Under Alcoa you're on the same Blount County limestone as Maryville. That rock is full of seams, and groundwater uses them like plumbing. A crawl space can sit dry through a whole summer and then pool water after a couple of days of steady rain, with the wet spot nowhere near the downspout that caused it. The same voids can let a block pier slowly sink. So at an Alcoa house we trace water first, then check every pier and the girder line, then look at the air. Getting the order right keeps the repair from coming undone.
Sudden water intrusion
Solution channels in limestone can deliver storm water to a foundation with almost no warning.
Sinkholes and localized settling
Voids in soluble bedrock let soil migrate downward, dropping piers and footings unevenly.
Shallow bedrock
Thin soil over rock limits how deep a drain line can go and changes where the water can be sent.

Alcoa questions
What homeowners ask us
I just moved to Alcoa for a job near the airport and I've never been under my house. Should someone check it?
It's a good idea, especially if the house is older or the inspection skipped the crawl space. Our estimate is free and takes about an hour. You'll see photos of everything under there, and if it all looks fine we'll tell you that.
Our Alcoa house only gets crawl space water after it rains two or three days straight. Why the delay?
Long rains saturate the soil and fill the cracks in the limestone underneath, and once there's nowhere left for it to go, water comes in from below or the side. Short storms run off before that happens. A perimeter drain to a sump pump is the usual answer for that pattern, but we'll check gutters and grading first.
My Alcoa crawl space has a vapor barrier, but it's torn and half the ground is bare. Can you replace it?
Yes, replacing a torn or missing vapor barrier is common work for us. Before we lay new plastic we look for the reason it's wet down there, since a new barrier over a water problem just holds the puddle. If humidity stays high, we'll talk about whether full encapsulation makes sense.
We're buying in Alcoa and the seller says the crawl space was encapsulated a few years ago. What should I look for?
Look for liner on the walls as well as the ground, taped seams, closed vents, and a working dehumidifier with a drain. Torn liner, water sitting on top of it, or a dead dehumidifier means the system has stopped doing its job. We can come out and tell you what condition it's in.
Is an Alcoa estimate on the same terms as one in Knoxville, or does the drive cost extra?
Same terms. No travel charge, a free on-site estimate, and 10 percent off your first service. Financing is available if the job turns out to be a bigger one.
The floor in our Alcoa hallway bounces and one bedroom door won't latch anymore. Is that a crawl space issue?
It often is. A cracked or sunk pier under the girder lets the floor drop a little, which pulls door frames out of square. We set adjustable steel jacks on proper footings and raise it slowly so the house can adjust. Doors don't always come all the way back, but the floor stops moving.
Our Alcoa crawl space smells like an old cellar and the ducts are sweating. What's behind that?
Sweating ducts mean the air under the house is humid enough to condense on cold metal. That moisture soaks the insulation, and it's where the musty smell comes from. Sealing the vents, lining the space and running a dehumidifier around 50 to 55 percent humidity usually stops both.
Can one crew handle Alcoa jobs that need waterproofing and crawl space repair at the same time?
Yes, and the two are often linked. Water under the house softens the ground under piers, so we usually fix the water first and then add supports. One crew, one written price.
I'd like to be there when you look at my Alcoa crawl space, but I work until 4. What are my options?
Our day runs 9 to 5, Monday through Friday, so a late afternoon slot often works. Tell us when you call and we'll try to fit the visit around you.
Will you give me a ballpark over the phone for my Alcoa house?
We don't quote over the phone, because two houses on the same street can need very different work. The estimate visit is free and gets you a written price you can hold us to.
Typical prices for every service are in the crawl space cost guide, and more answers are on the FAQ page.
