Our Waterproofing Services
We waterproof seven parts of a home or building, each with a system matched to how water reaches it, and we take on commercial and multi-unit projects.
Basement Waterproofing
Basement waterproofing seals below-grade walls and floors against water pushed in by wet soil. Our basement waterproofing work closes cracks and joints, then adds a barrier to the inside or outside of the wall. It covers subterranean spaces too, such as lower levels built into a hillside and garages below grade.
Foundation Waterproofing
Foundation waterproofing protects the concrete where a building meets the soil, whether or not there’s a basement. We seal cracks and joints in footings and foundation walls, including the short stem walls under raised-floor homes; the foundation waterproofing page covers both sides of the wall.
Crawl Space Waterproofing
Crawl space waterproofing keeps rain runoff from collecting under raised-floor homes, which are common in older Los Angeles neighborhoods. Our crawl space waterproofing seals the stem walls and low openings, then dries the space and its framing.
Roof Waterproofing
Roof waterproofing seals flat and low-slope roofs, which shed water slowly, along with the flashing on tile roofs. The job covers the surface, seams, parapet walls and flashing around vents and skylights, and our roof waterproofing page explains each one.
Deck Waterproofing
Deck waterproofing turns a deck over a room or garage into a roof you can walk on. Our deck waterproofing adds a walkable membrane or coating and seals the door threshold and wall connection, two spots where deck leaks often start.
Balcony Waterproofing
Balcony waterproofing seals the walking surface, edges and wall joint so water can’t reach the framing or the room below. That joint with the building is where balcony leaks often start, so our balcony waterproofing work spends the most time there.
Stucco Waterproofing
Stucco waterproofing helps a porous stucco wall shed rain once its cracks and flashing are repaired. Our stucco waterproofing service applies an elastomeric coating or a clear water repellent matched to the wall.
Commercial and Multi-Unit Waterproofing
Commercial waterproofing covers apartment buildings, condos and commercial property, where one failed surface can wet several units. We trace the leak across units before we recommend a fix, and large and multi-unit projects have their own commercial waterproofing page.
Signs Your Property Needs Waterproofing
The clearest sign is water that shows up with the rain and goes away when it dries out. Look for:
- Damp basement or foundation walls after storms, or white chalky deposits on the concrete
- A musty smell in lower rooms, or wet soil under a raised-floor house
- Puddles that sit on a flat roof, deck or balcony long after rain
- Cracked, peeling or blistered coatings on decks, balconies and roofs
- Ceiling stains below a deck or balcony, or on the top floor
- Cracks in stucco near windows, doors and corners, with stains inside the same wall
Don’t caulk or patch the spot where water shows up. A fresh bead of caulk can look like a fix for a season while the wall behind it keeps getting wet.

Our Waterproofing Process
Every waterproofing job follows five steps: inspect, find where water gets in, repair that entry point, install the system and check the result.
1. Inspection
We walk the property inside and out and scan the wet areas with an infrared camera.
2. Finding Where Water Gets In
We confirm the entry point before we recommend a system. Our water leak detection work uses thermal imaging, moisture mapping and other non-invasive testing, so the fix targets the surface that’s actually failing.
3. Repair and Preparation
The entry point gets fixed first: cracked concrete, failed flashing, broken stucco or wet framing. Then we clean and prime the surface so the new system bonds.
4. Installing the System
We apply the membrane, coating or sealant that suits the surface and its exposure to sun, rain and foot traffic. On below-grade walls that means choosing a side, and our guide to interior vs. exterior waterproofing compares the two.
5. Final Check and Upkeep
Once the system is in, we recheck the area with moisture readings. You also get the upkeep the system needs and the warning signs that mean it’s time for a look.
How Much Does Waterproofing Cost?
Waterproofing costs $2,275 to $2,600 for a small project up to 3,000 sq. ft., and larger projects run from $3,000 to $150,000 or more.
| Service | Price |
|---|---|
| Basic Inspection (about 15 to 20 minutes, infrared camera) | $375 to $575 |
| Detailed Inspection (up to about 1 hour, one home or unit up to 3,000 sq. ft.) | $575 to $775 |
| Multi-Unit / Larger Property Inspection (up to 5 units or properties, 3,500 to 10,000 sq. ft.) | $975 to $1,500 |
| Water Intrusion Testing | $1,275 to $1,850+ |
| Complex Water Testing | $1,950 to $2,600+ |
| Small project (up to 3,000 sq. ft.) | $2,275 to $2,600 |
| Medium project (3,000 to 10,000 sq. ft.) | $3,000 to $10,000 |
| Large project (10,000 to 50,000 sq. ft.) | $10,000 to $50,000 |
| Large waterproofing project | $50,000 to $150,000+ |
Size sets the tier. Inside that tier, three things move the price: how much has to be repaired before the system goes on, how hard the surface is to reach (exterior foundation work means digging) and which system the surface needs.
Water testing isn’t included in inspection prices. When we do the work, the fee for a Basic or Detailed Inspection is credited toward the cost of the work. Multi-Unit / Larger Property Inspection fees and water testing fees are not credited. Your final price comes in a written estimate after the inspection.

Waterproofing FAQs
How long does waterproofing last?
Waterproofing doesn’t have a fixed lifespan in years. Service life depends on the system, the surface prep, the sun and foot traffic it gets and how it’s maintained. We tell you what upkeep your system needs and which warning signs mean it’s time for a check.
Is waterproofing disruptive?
Waterproofing usually isn’t disruptive. Most of the work happens outside the living space, on the roof, deck, balcony or exterior walls. Foundation and basement jobs can be bigger, because exterior work sometimes means digging along the wall. We explain which areas we need to reach before work starts.
When should I schedule waterproofing in Los Angeles?
The ideal window for waterproofing in Los Angeles is late spring through early fall, before winter storms arrive. Most of Southern California’s rain falls between late fall and early spring, and waterproofing systems need dry surfaces to bond. If water is already getting in, don’t wait for summer. We can find and repair the entry point now.
How do I choose a waterproofing contractor?
Choose a waterproofing contractor that finds the entry point before it recommends a system. Check the contractor’s license number with the California Contractors State License Board, and ask for a written scope and price before work starts. Ours is CSLB #998184, and our prices are listed on this page.
