A lot of Island Lake, IL exterior waterproofing failures trace back to a footing drain that was installed without proper slope, which means it never actually moved water the way it was supposed to. We verify slope during installation, not just at design.
Exterior work involves excavation near the foundation, and every crew member is trained and insured for that specific scope.
Excavation equipment and membrane materials are staged locally so an exterior project doesn't wait on out-of-town logistics.
Pricing is quoted per linear foot of foundation wall being treated, based on an on-site measurement, not a phone estimate.
Membrane seams are overlapped and sealed to manufacturer spec so the barrier performs as designed for decades, not just years.
We scope every Exterior Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.
This is the most comprehensive Island Lake, IL waterproofing fix available, addressing the wall itself rather than just managing water after it gets in.
A perforated footing drain collects groundwater at the base of the foundation and routes it away before it can build pressure against the wall.
We regrade the perimeter to direct surface water away from the wall, typically paired with downspout extensions.
Window wells collecting water get excavated, fitted with a gravel bed, and tied into the exterior drain system so they stop acting as a funnel toward the foundation.
Downspouts discharging within a few feet of the foundation send roof water directly toward the problem — we extend them well clear of the wall.
We ask about grading, downspout placement, and where interior water is showing up to narrow down the likely exterior cause.
A technician walks the exterior perimeter, checks grading slope, and identifies where excavation would be needed for a membrane or footing drain fix.
We explain what's included in landscaping restoration so there's no confusion after backfill.
Excavation, membrane installation, and backfill for a typical residential wall section usually take a few days depending on access and weather.
"Interior fixes hadn't worked for us — turned out the real problem was grading pushing water straight at the foundation. Exterior correction solved it."

"Excavation crew was careful with our landscaping and put everything back close to how it looked before."
— Island Lake Customer
"Window well kept flooding every storm. They excavated, added drainage, and resealed the window frame while they were at it."

"Fast turnaround given how much digging was involved."

Interior systems manage water after it enters; exterior systems stop water from reaching the wall in the first place, which is more invasive but often more permanent.
We discuss landscaping impact during the estimate so there are no surprises.
We measure your specific foundation during the on-site inspection rather than assuming a standard depth.
We'll walk through both options and their trade-offs so you can make an informed choice.
Yes — grading correction and downspout extension are often standalone fixes that resolve a surprising number of Island Lake, IL water intrusion issues on their own.
