Interior Drainage System Installation
When it comes to keeping your basement dry, a full-perimeter drainage system is the most efficient way to keep ground water from reaching your basement floor.
At Summit Waterproofing we install Grate Products’ patented GrateDrain™ Basement Waterproofing Drainage System. We excavate around the inside edge of the foundation, then install perforated pipes to collect and redirect water to a sump pump for removal.
GrateDrain™ is custom built for every basement, and makes it easy to keep your basement dry.

Sump Pump Installation and Back Up Battery Installation
A sump pump is designed to remove water that collects in a sump basin at the lowest point of your basement.
At Summit Waterproofing, we typically install the GrateSump™ Sump Pump Liner with the FastSump™ Sump Pump.
We also offer battery backup systems, which are critical during storms. Power outages often happen at the exact time your sump pump is needed most. A backup battery system keeps water moving out of your basement even if the power goes out.
If your current system is older, undersized, or struggling to keep up during heavy rain, it may be time for an upgrade.
Call 703-291-1516 or submit a contact form for a free sump pump installation estimate in Alexandria.
Exterior French Drain Installation
Exterior French drains are designed to stop water before it ever reaches your foundation. Instead of dealing with water once it gets inside, this system works from the outside by intercepting groundwater and redirecting it away from your home.
In Alexandria, this is especially effective for homes with poor yard drainage or properties where runoff water slopes toward the home.
Our exterior French drain installation involves excavating a sloped path and installing a drainage system that captures groundwater and redirects it away.
During installation, we:
- Set the correct slope and discharge path so water is carried safely away from the home
- Install a perforated drainage pipe system at the proper depth to capture groundwater
- Surround the pipe with gravel to allow water to flow freely into the system

Crawl Space Encapsulation Services in Alexandria, VA
Crawl space encapsulation is the process of sealing off the space beneath your home to control moisture and protect the structure. It’s one of the most effective ways to deal with ongoing moisture issues and protect the long-term health of the home.
A typical Summit encapsulation system includes:
- Heavy-duty vapor barrier installation
- Sealing vents, gaps, and entry points
- Addressing drainage issues if present
- Sump Pump installation
- Dehumidifier installation
At Summit Waterproofing we seal all vents and gaps to prevent humid outside air from entering. Then we install a sump pump system and heavy-duty vapor barriers along the floor and walls. We also install dehumidifiers based on the square footage of your space to keep humidity under control year-round.
Every space is a little different so there’s no one-size-fits-all solution when it comes to encapsulation. Every crawl space encapsulation starts with a free inspection and detailed estimate based on the specifications of your space.
If you’ve been dealing with moisture issues in your crawl space call us at 703-291-1516 or submit a contact form for a free encapsulation estimate in Alexandria.
Crawl Space Repair Services in Alexandria
In Alexandria, we commonly see crawl spaces with moisture damage that has been building for years. Floor joists start to weaken, wood begins to rot, and the floors above can feel soft or uneven. These issues don’t fix themselves and tend to get worse the longer they’re left alone.
Our crawl space repair services in Alexandria include:
- Wet crawlspace repair
- Support post repair
- Crack repair
- Floor Joist reinforcement
- Sagging floor repair
- Crawlspace door repair and replacement
- Crawlspace insulation removal & replacement
Fixing the structure without addressing the cause will only lead to the same problems coming back. In many cases, repairs go hand-in-hand with encapsulation or moisture control.
At Summit Waterproofing, every crawl space repair starts with a full inspection. From there, we provide a clear, no-obligation estimate based on what your home actually needs.
Call us at 703-291-1516 or submit a contact form for a free crawlspace repair estimate in Alexandria.
Structural Crawl Space Repairs We Handle
Structural crawl space repairs we offer include:
- Floor joist repair and replacement
- Support beam reinforcement
- Subfloor repairs
- Adding or adjusting supports
Each repair is based on the condition of your crawl space and how far the damage has progressed.

Foundation Crack Repair in Alexandria, VA
Our foundation crack repair in Alexadria focuses on identifying the cause of the crack and sealing it properly to prevent further problems.
Addressing foundation cracks early helps prevent them from widening and turning into more costly repairs.
Our foundation crack repair services consist of:
- Identifying the cause of the crack
- Sealing cracks to prevent water intrusion
- Reinforcing the area
The right repair method depends on the type of crack, how it formed, and whether it’s still moving. If you’ve noticed cracks in your basement walls or foundation, it’s worth having them inspected before they begin to leak or spread.
