Foundation Repair, Basement Waterproofing & Crawl Space Encapsulation in Johnson City, TN

A floor that sits low toward one end, cracking through the block, a door that stopped shutting on that same side. On the Tree Streets the footings are old and shallow, and a century of water running past them has taken material away a little at a time. What is left underneath eventually stops carrying the weight.

What we do depends on how far it has gone. Supports get driven down past the softened ground to something that will hold, then loaded to bring the corner back toward level. Where a wall has moved rather than dropped, it gets braced instead of lifted, which is the commoner answer on the Boones Creek slabs. And where the water is still arriving, drainage goes in first, because ground that keeps taking on water will keep moving whatever we put in it.

The first job is telling those apart. Levels through the rooms, a look underneath, and a walk outside to find where the water comes off the slope and where it ends up. You get told what is moving, what is cosmetic, and what it costs before anything starts.

Two questions come with this job every single time: will insurance pay for it, and what is the cheapest way to do it. More people in Johnson City ask us about basement water than about anything else. In a Tree Streets basement water shows at the joint where the wall meets the floor, or halfway up the block, and it shows within a few hours of a real downpour rather than days later.

There are two honest routes. From the inside, a drain goes in around the perimeter below the floor and runs to a pump, which takes the water that has already got through and puts it outside. From the outside, the wall gets dug clear, sealed across its face, and a drain laid at the footing so the water never reaches it. Outside costs more and lasts longer.

Which one is right depends on how much water and where it comes from, and around Boones Creek that answer is different street to street. Interior work is the common answer. Exterior is the answer when the ground outside stays saturated for days at a time. We will tell you which you are looking at.

More people here search for this than for anything else we do. The signs are upstairs rather than down: a smell that meets you in the hall, insulation sagging wet between the joists, floors that never quite feel warm. The ground under a house on a crawl space is open dirt, and open dirt gives off water the whole time.

Encapsulation shuts that off. A heavy liner goes across the whole floor, up the piers and up the walls, taped at the seams and sealed at the top. Vents that were letting damp outside air in get closed, and through Boones Creek that alone changes the reading. Where water is actually running in under the house, a drain and a pump go in below the liner first, because sealing over standing water only hides it.

The rooms above change within days. The smell goes, the floors stop feeling cold, and the heating stops fighting the crawl space. In the older houses through the Tree Streets it also keeps the joists dry, which is the part that decides how long the floor lasts.

On a slope the rain does not have to land on your property to become your problem. It runs down from above, meets the first thing in its way, and stops there. Around the Tree Streets you see it as ground that stays soft on the uphill side for days, or water standing at the corner where a downspout lets go.

A drain gives it somewhere better to be. A trench is cut on the side taking the water, lined so soil cannot work its way in, and a perforated pipe is bedded in washed stone. It is set at a depth and a fall that moves water away under its own weight, then let out well clear of the house. Downspouts get tied in rather than left to dump at the wall.

Depth and distance from the wall are what decide whether it works, and they are also why the ones people dig themselves stop working after a couple of winters. Through Boones Creek, where the lots are wider, there is usually room to put it far enough out. Done properly this is often the cheapest thing that fixes a foundation problem.

A barrier covers the dirt and nothing more. It is the smaller version of encapsulation, and for a crawl space that is damp rather than wet it is often all that is wanted. The builder-grade sheeting most houses got is thin, torn by whoever has been down there since, and it rarely reaches the corners.

New sheeting goes down heavier than what came out, overlapped and taped at the seams, and run up the walls far enough that moisture cannot come around the edge. Whatever has been left under there over the years gets cleared first. In the low crawl spaces common through the Tree Streets that clearing is most of the work.

It is worth saying plainly where the limit is. A barrier handles water coming out of the ground and nothing else. It does nothing about damp outside air through open vents, and nothing about water running in after a storm. If either of those is what you have, this is not the job you want, and around Boones Creek it often is not the job we end up quoting.

The drain collects the water and the pump is what actually gets rid of it, so an interior system is only ever as good as the pump sitting in it. It is also the part that fails, usually in the middle of the storm that needed it most, which is when people find out the float was stuck or the discharge line was frozen shut.

A proper install starts with the pit, sized and set below the floor so water reaches it instead of pooling on a Tree Streets basement slab. A cast-iron pump lasts longer than a plastic one and runs cooler. The discharge goes well away from the house, not to the corner where it can come straight back in. A check valve keeps what has been pumped out from running back down.

Battery backup is worth the money here, and through Boones Creek where storms take the power out it is not optional. The rain that fills a basement is often the same weather that drops the power, and a pump with no power is an ornament. We will also tell you if your existing pump is fine, because plenty of them are and replacing a working pump is not a repair.
