Sump Pump Services in Mount Prospect, IL
A properly functioning sump pump system is the backbone of a dry basement. When groundwater rises around your home, the sump pump collects that water and safely discharges it away from the foundation before it can cause flooding or damage.
Because Mount Prospect homes vary widely in age, construction style, and drainage design, sump pump systems must be installed, repaired, and maintained correctly to perform when it matters most.
Sump Pump Installation
If your home does not have a sump pump—or relies on an outdated or undersized system—we provide professional sump pump installation tailored to Mount Prospect conditions. This includes proper pit sizing, high-quality pumps, sealed lids, and discharge lines that move water far enough away to prevent recycling back toward the foundation.
Each installation is designed around your home’s layout and long-term waterproofing needs, not a one-size-fits-all approach.
Sump Pump Replacement
Most sump pumps have a lifespan of about 7 to 10 years. If your pump is nearing that range, replacement is often the safest and most cost-effective option—especially if your basement has flooded before.
We provide sump pump replacement in Mount Prospect using modern, high-performance systems designed to handle higher water volumes and increased groundwater pressure. Replacement is also an ideal time to upgrade capacity or add backup protection.
Sump Pump Repair
Sump pump problems rarely happen at convenient times. If your pump is running nonstop, failing to activate, making unusual noises, or struggling to keep up during rain, fast action is critical.
Our sump pump repair services in Mount Prospect focus on identifying the root cause—whether it’s a float switch issue, motor wear, clogged discharge line, or check valve failure. We don’t just get the pump running again; we make sure it will perform reliably during the next major storm.
Battery Backup Sump Pump Systems
Power outages often happen during severe storms—exactly when sump pumps are needed most. Battery backup sump pumps provide an extra layer of protection by keeping your system running even if the power goes out or the primary pump fails.
Many Arlington Heights homeowners choose to add a backup system for peace of mind, especially if they have a finished basement or valuable items below grade.
Sump Pump Maintenance
Regular maintenance helps prevent unexpected sump pump failure. Our sump pump maintenance services include system testing, pit cleaning, float adjustment, and discharge line inspection. Proactive maintenance can significantly extend the life of your pump and reduce emergency repair calls.
Crawl Space Repair Services
Homes with crawl spaces face similar moisture risks as basements. Excess moisture can lead to mold growth, wood rot, and poor indoor air quality.
Our crawl space repair services help control moisture, protect structural components, and improve overall home health. Crawl space solutions are often recommended alongside basement waterproofing for full-property protection.
Foundation Crack Repair in Mount Prospect, IL
Foundation cracks are one of the most common causes of basement leaks in Mount Prospect homes. Even hairline cracks can allow water to seep inside during heavy rain or snowmelt, leading to damp walls, musty odors, and potential mold growth.
We provide professional foundation crack repair that stops leaks at the source.
Common Signs of Foundation Crack Problems
- Water leaking through basement walls
- Visible vertical or stair-step cracks
- White, chalky residue on walls (efflorescence)
- Increased basement humidity or odors
- Cracks that widen over time
Our crack repair methods are designed to permanently seal cracks and prevent future water intrusion—not just hide the problem.
Drain Tile Installationin Mount Prospect, IL
In some Mount Prospect homes, sump pumps alone are not enough to manage groundwater pressure. When water builds up around the foundation, it needs a controlled path to the sump system.
Interior drain tile installation collects groundwater along the basement perimeter and directs it into the sump pump, relieving pressure on foundation walls and preventing leaks. Drain tile systems are often installed alongside sump pumps and crack repair for complete basement waterproofing.
Basement Window Well Drains
Window wells are another common entry point for water. Without proper drainage, rainwater can collect around basement windows and leak inside.
We install window well drains that connect to your sump pump or drainage system, allowing water to drain safely and reducing the risk of leaks and window damage.
A Local, System-Based Approach
Mount Prospect’s soil composition, aging foundations, and seasonal weather patterns create unique waterproofing challenges. Our local experience allows us to tailor each solution—whether it’s sump pump installation, crack repair, or drain tile—to your specific property.
We don’t believe in temporary fixes or generic systems.

Frequently Asked Questions – Mount Prospect Basement Waterproofing
Not all foundation cracks are structural, but any crack that allows water into your basement should be repaired. Vertical cracks in poured concrete walls are common in Northern Illinois and often result from soil settlement or hydrostatic pressure. If a crack leaks during rain, appears to be growing, or is accompanied by musty odors or efflorescence (white powder on walls), it’s a strong sign that professional repair is needed. A proper inspection helps determine whether the crack is cosmetic, water-related, or structural.
Yes. Many older homes in Mount Prospect were built before modern drainage and waterproofing standards existed. These homes may have undersized sump pits, outdated pumps, or no drainage system at all. In these cases, upgrading the sump pump, adding a drain tile system, or installing a battery backup pump is often necessary to handle today’s groundwater conditions and prevent recurring basement water issues.
Foundation cracks can expand over time due to soil movement, freeze-thaw cycles, and ongoing water pressure. What starts as a small crack may eventually allow more water inside or contribute to structural stress if left unaddressed. Early foundation crack repair helps prevent leaks, reduces moisture problems, and protects the long-term stability of your home.
The best repair method depends on the type, size, and cause of the crack. For leaking cracks in poured concrete foundations, professional crack injection using polyurethane or epoxy materials is often the most effective solution. These materials seal the crack from the inside and bond with the foundation wall to prevent future water intrusion. In cases involving structural movement or block wall foundations, additional stabilization or drainage solutions may be recommended.
In some Mount Prospect homes, a sump pump alone is not enough. If water pressure is building up along the foundation walls, an interior drain tile system may be required to collect groundwater and direct it to the sump pump efficiently. Drain tile helps relieve pressure on the foundation and prevents water from entering through wall-floor joints and cracks.
Power outages often happen during severe storms—the same time sump pumps are needed most. Without power, a standard sump pump cannot operate, which can quickly lead to flooding. Installing a battery backup sump pump provides continued protection by automatically activating when the primary pump or power supply fails.
We recommend professional sump pump inspections at least once per year. Homes with high groundwater levels, finished basements, or older systems may benefit from more frequent checks. Regular inspections help identify issues like failing float switches, clogged discharge lines, or worn motors before they cause a basement flood.
Yes. Window wells are a frequent source of basement leaks, especially during heavy rain. If a window well lacks proper drainage, water can pool against the window and seep inside. Installing window well drains connected to the sump or drainage system helps move water away and reduces the risk of leaks and window damage.
Absolutely. Moisture in crawl spaces can lead to mold growth, wood rot, and poor indoor air quality. That moisture can travel upward into living areas, affecting comfort and health. Crawl space repair and moisture control help protect both the structure of your home and the air you breathe.
Yes. A dry, protected basement is a major selling point. Basement waterproofing reduces the risk of future damage, improves usable space, and gives buyers confidence that the home has been properly maintained. It also helps avoid inspection issues during resale.
Every home is different. The best way to determine the right solution is with a professional basement inspection. By evaluating your sump pump, foundation, drainage, and moisture conditions, we can recommend a system tailored to your home’s specific needs—without unnecessary upgrades or pressure.
