Exterior Basement Waterproofing in Lexington, KY
Exterior Foundation Waterproofing Contractors in Lexington, KY
Exterior basement waterproofing in Lexington, KY stops water on the outside of your foundation, before it ever touches the basement wall. Our crews dig down along the wall to the footing, repair or install drainage, and apply a membrane over the foundation so the wall stays dry from the soil side. Reed’s Home Solutions handles this work for homes in Lexington, Fayette County and the towns around them.
It is the right approach when water is moving through the wall assembly itself: porous block, cracked mortar joints, a failed old coating, or a footing drain that has quit working. Rather than managing water after it gets in, you remove the reason it gets in. Every project begins with a free, no-obligation inspection so we know whether the problem really belongs outside.
Exterior work is the biggest of our waterproofing options, so we want you to choose it for the right reasons. If the inspection shows that interior basement waterproofing or a lighter fix will solve the problem, we will tell you that.
How Water Reaches Lexington Foundations From the Outside
Look at how your lot sheds water and the cause is often obvious. Central Kentucky soil is clay-heavy, and clay drains slowly. After a heavy spring rain it stays saturated against the foundation and builds hydrostatic pressure on the wall. Hillside and sloping lots send surface runoff straight toward the house, and limestone close to the surface can hold water in pockets around the footing.
Roofs and yards add to it. Downspouts that dump at the corner of the house, gutters packed with leaves, soil that has settled toward the foundation and flower beds that trap water all feed the same wall. Older Lexington homes often have clay tile footing drains from the original build that have cracked, filled with silt or been crushed over the decades.
Gaps around basement entryways and window wells are another common path. When the drain at the bottom of a well clogs or the threshold seal gives out, water pours in at one spot even though the rest of the wall is fine. That is why we study the whole outside of the house during your inspection, not just the wet patch inside.
What's Included in Exterior Basement Waterproofing in Lexington
Depending on what your inspection finds, an exterior project combines some or all of these.
Foundation Membrane & Site Waterproofing
We excavate down to the footing and apply an exterior waterproofing membrane to the wall. A moisture barrier goes on porous concrete or block, and cracks are sealed and reinforced before anything is covered. We assess the site first, because drainage, grading and soil all decide how the membrane should be installed.
Footing Drain Restoration
We inspect the existing footing drain, clean out silted lines and replace pipe that is broken or crushed. Grading is corrected where needed, and new perforated pipe with filter fabric is tied into the waterproofing and sump system. It is the same idea as a French drain, placed right at the base of the wall.
Entryway Drainage Repairs
We inspect walkout entries, stairwells and window wells, clear or replace clogged drains and correct the grading that sends water to them. Thresholds are sealed so water stops coming in under the door.
Why Lexington Homeowners Choose Exterior Waterproofing
Fixing the problem on the soil side has some advantages that inside work cannot match.
- It stops water at the outside wall. Moisture never gets the chance to soak into the foundation.
- It protects the structure. Repeated wet and dry cycles widen cracks over time, and keeping the wall dry slows that down.
- It improves drainage across the whole lot. Grading, downspout routing and entry drains get fixed along with the wall.
- It deals with the source, not the symptoms. You are repairing the failed membrane or footing drain that let the water in.
- The workmanship is warrantied. That includes the drain and entryway repairs we install.
Signs Your Basement Needs Exterior Waterproofing Instead of Interior
No single sign settles it, but these patterns point to a problem outside the wall.
- Water entering at one spot near a downspout, entry or window well
- Wet walls above the floor line, not only at the wall-floor joint
- Crumbling, flaking or bubbling old coating on the outside of the foundation
- Soil sloping toward the house or standing water along the foundation after a storm
- Cracks that open wider and leak harder after wet seasons
- A footing drain you know is old, clogged or has never been checked
How an Exterior Waterproofing Project Works in Lexington
The work moves along the outside of the house in a clear order.
Excavate to the footing
We dig along the affected wall to the footing. Lexington’s clay and rock can make this slower than it looks, which is one reason we plan access and equipment ahead of time.
Clean, inspect and repair the wall
The exposed foundation is cleaned and checked. Cracks are sealed or reinforced, and any damage to the wall or old coating is repaired before the new system goes on.
Install the membrane and drainage
The waterproofing membrane is applied, and the footing drain is cleaned, repaired or replaced with new perforated pipe wrapped in filter fabric and set in washed gravel.
Backfill and regrade
The trench is backfilled, and the soil is graded so surface water runs away from the house instead of back toward it.
What Affects the Cost of Exterior Waterproofing in Lexington?
Exterior work costs more than most other basement waterproofing options because of the digging, and the price swings with the site. The biggest factors are how much of the foundation needs to be exposed, how deep the footing sits and what is in the way, such as a deck, a patio, a driveway or mature trees and shrubs.
Soil conditions matter too. Rock and heavy clay slow excavation, and a hillside lot can change how equipment gets in. The scope inside the trench counts as well: membrane only, a new footing drain, entryway repairs or all three. Backfilling and regrading are part of the plan, not an afterthought.
We do not quote exterior work over the phone. The free inspection gives you a written price and a schedule for your project. If you want to spread the cost out, we can walk you through financing at the same visit.
Pairing Exterior Waterproofing With Foundation and Crawl Space Work
Because the foundation is already exposed, an exterior project is a good moment to deal with other issues on the wall. If the inspection shows stair-step cracks, a bowing wall or settlement, we can bring in foundation repair as part of the same plan. Homes with a vented or partial crawl space attached to the basement can also benefit from crawl space repair.
Inside the house, a sump pump usually remains the exit point for the drainage system, and crack repair handles stubborn leaks. Once the walls are dry, basement insulation makes the space comfortable and cuts energy loss.
Which Approach Fits Your Lexington Basement?
Exterior and interior waterproofing solve the same problem from opposite sides of the wall. This is how we decide between them.
Choose exterior when
The membrane has failed, the footing drain is damaged or silted, cracks are actively moving or the outside drainage is the cause. The area around the foundation is open enough to excavate.
Choose interior when
Access outside is blocked, you want a faster repair that does not disturb the yard, or water comes mainly through the wall-floor joint. No excavation is needed.
Choose a lighter fix when
The problem is limited. Many homes only need a French drain or a properly sized sump pump, and the inspection will say if yours does.

Exterior Basement Waterproofing in Lexington: Frequently Asked Questions
How is exterior waterproofing different from sealing the inside of my basement?
Sealing the inside tries to hold back water that has already reached the wall. Exterior waterproofing keeps it away from the wall in the first place. Interior paint or sealer can fail under hydrostatic pressure, while a membrane and footing drain on the outside relieve that pressure at its source.
Do you have to excavate the whole house, or just repair the footing drain?
It depends on what the inspection finds. Some projects expose only the wall that leaks, and some are limited to restoring a footing drain or fixing an entryway. We only dig as much as the problem requires.
What causes a footing drain to fail?
The usual causes are silt and roots clogging the pipe, old clay tile cracking or collapsing, and a drain that was never installed correctly. Poor outlet routing can also cause it to back up. A failed footing drain lets groundwater rise against the wall.
Why does water leak near my basement entryway or window well?
Those spots collect water by design, so when the drain at the bottom clogs or the threshold seal fails, the water has nowhere to go but in. Grading that slopes toward the opening makes it worse. We inspect, clear the drain, correct the grading and seal the threshold.
Is exterior waterproofing warrantied?
Yes. The workmanship on our drain and entryway repairs is warrantied, and we go over what the coverage includes during your estimate.
How long does exterior waterproofing take?
The timeline depends on how much foundation is exposed, soil conditions and the scope of repairs. We put the schedule for your project in your free estimate.
Will it tear up my landscaping?
Digging along the foundation does disturb the ground next to it. We plan around plants, patios and walkways where we can, and we backfill and regrade when the work is done. Tell us what matters most to you during the inspection so it goes into the plan.
What signs point to exterior rather than interior waterproofing?
Water entering at a single spot near an entry or window well, wet walls well above the floor, a failing coating on the outside of the wall and poor grading all point outside. Water only at the wall-floor joint often points to interior drainage. Many homes show a mix, which is why we inspect before recommending.
Can exterior waterproofing be done in winter?
Frozen or saturated ground can slow excavation, so some projects are better scheduled for milder weather. Not every job has to wait, and we will tell you what makes sense for your situation. If the basement is actively leaking, interior options may offer faster relief in the meantime.
How much does exterior waterproofing cost in Lexington?
It varies with how much foundation is exposed, the depth of the footing, what is in the way and what repairs the wall needs. Your free inspection produces a firm written price, and financing is available if you want to spread it out.
