Basement Waterproofing Services in Pasadena, CA

Basement water can enter through a wall, floor, crack, joint, or pipe opening. It can also collect below the property because of poor drainage. We review the problem first, then explain which service may fit the water source and property layout.

Our basement waterproofing services

Detailed options for different water paths.

The visible wet area may not show where the leak began. Each service starts with the source, accessible conditions, and the way water moves through the property.

01

Active water

Wet Basement Repair

Water may appear after rain, near one wall, or along the basement floor. Our service focuses on finding the likely water path through wall cracks, floor joints, pipe openings, drainage, or exterior grading.

Get Help With a Wet Basement →

Wet basement repair may help with:

  • Water after heavy rain
  • Basement wall leaks
  • Floor seepage
  • Cove-joint leakage
  • Damp walls
  • Musty odors
  • Standing water
  • Mineral deposits
  • Repeat leaks

The repair may involve crack sealing, drainage, waterproofing, or sump-pump work. The right service depends on the cause.

02

Below-grade walls

Foundation Waterproofing & Crack Repair

Wet soil can bring water to foundation cracks, joints, and porous wall sections. The work should match the crack condition, wall material, drainage, and accessible foundation area.

Request a Foundation Leak Inspection →

The work may include:

  • Foundation-wall inspection
  • Concrete crack repair
  • Crack injection
  • Foundation sealing
  • Exterior membranes
  • Drainage boards
  • Foundation drainage
  • Interior moisture control

A small stable crack may need direct repair. A wide or moving crack may require a separate structural review.

03

Method comparison

Interior & Exterior Basement Waterproofing

Interior systems manage water from inside using drainage channels, wall barriers, crack repair, and sump pumps. Exterior systems protect the soil side through excavation, preparation, membranes, and footing drainage.

Compare Interior & Exterior Options →

Interior may fit when:

  • Water enters near the floor
  • Exterior access is limited
  • Below-slab water needs control
  • A sump system is required

Exterior may fit when:

  • Water moves through an outside wall
  • Wet soil stays against the foundation
  • An old barrier has failed
  • Exterior cracks need direct access

Some basements need both methods. The water source should guide the final decision.

04

Water collection

French Drains & Basement Drainage

Interior drains may sit near the wall or below the floor edge. Exterior drains can collect groundwater or runoff before it reaches the foundation. The correct route depends on the source, slope, and outlet.

Request a Drainage System Review →

Drainage services may include:

  • Interior French drains
  • Exterior French drains
  • Perimeter drains
  • Foundation drainage
  • Drainage channels
  • Gravel and perforated pipe
  • Sump-basin connections
  • Planned discharge routes

Surface drains collect visible runoff. French drains collect water moving through soil.

05

Water removal

Sump Pump Installation & Repair

A sump pump removes water after a basement or crawl-space drainage system collects it. Pump size, basin, power supply, check valve, and discharge route must work together.

Schedule Sump Pump Service →

Our pump service may include:

  • New pump installation
  • Sump pump repair
  • Pump replacement
  • Float-switch checks
  • Basin inspection
  • Discharge-line review
  • Check-valve service
  • Battery backup options
  • Routine maintenance
06

Below the home

Crawl-Space Waterproofing

Crawl spaces can collect moisture from damp soil, runoff, plumbing leaks, and wet foundation walls. The first visible sign may be standing water—or only a musty smell inside the home.

Request a Crawl-Space Inspection →

The service may include:

  • Crawl-space drainage
  • Ground vapor barriers
  • Sump pump installation
  • Foundation crack sealing
  • Wall moisture control
  • Encapsulation options
  • Humidity-control planning

A vapor barrier slows soil moisture; it does not remove standing water. Active water may need drainage before a barrier is installed.

07

Focused leak repair

Basement Leak Repair

A recurring leak needs more than a surface patch. We compare the wet area with cracks, wall-floor joints, pipe penetrations, window wells, exterior runoff, and drainage so the repair addresses the route water is actually using.

Explore Basement Leak Repair →

A focused leak review may cover:

  • Leak timing and rain history
  • Wall and floor entry points
  • Window-well drainage
  • Pipe and utility penetrations
  • Interior water management
  • Exterior grading and runoff

Direct sealing may be enough for a stable, accessible opening. Repeat seepage across a wider area may need drainage or a broader waterproofing system. The dedicated page explains how those decisions are made.

08

Cracks and joints

Basement Crack Repair

Cracks can be dry, leaking, stable, or moving. Those differences matter. We review the crack pattern and surrounding moisture before discussing injection, surface sealing, drainage support, or a structural referral.

Explore Basement Crack Repair →

The assessment considers:

  • Crack direction and width
  • Signs of recent movement
  • Water staining or mineral deposits
  • Wall material and accessibility
  • Nearby drainage pressure
  • Repair history

A waterproof repair should not disguise active structural movement. If the pattern suggests a foundation concern, the structural issue is separated from the moisture-control scope.

09

Managed moisture boundary

Basement Encapsulation

Encapsulation covers appropriate exposed surfaces with a durable moisture-control layer. It can help separate interior air from damp masonry or soil, but active leaks and standing water must be addressed first.

Explore Basement Encapsulation →

A complete plan may include:

  • Moisture-source inspection
  • Surface preparation
  • Sealed barrier installation
  • Drainage beneath or beside the system
  • Sump pump coordination
  • Humidity monitoring

The goal is not simply to cover a wall or floor. The barrier, seams, drainage, and indoor moisture strategy need to work as one system.

10

Foundation-side water

Foundation Leak Repair

Foundation leaks may follow a crack, construction joint, porous wall section, or opening around a utility. We inspect both the visible entry point and the exterior conditions that may be keeping soil wet against the foundation.

Explore Foundation Leak Repair →

Possible repair components:

  • Crack injection or sealing
  • Joint and penetration repair
  • Interior drainage
  • Exterior excavation where practical
  • Waterproof membrane work
  • Footing-drain review

The most durable scope controls both the opening and the water pressure behind it. Structural movement, plumbing leaks, and condensation are identified separately so the wrong repair is not applied.

Common basement and foundation problems

Finding the cause helps avoid the wrong service.

The same sign can have different causes. A musty smell, for example, may come from damp soil, a plumbing leak, standing water, or wet materials.

Water after rain Leaking foundation walls Floor seepage Wet wall-floor joints Foundation cracks White powder on masonry Peeling basement paint Standing crawl-space water Wet insulation Musty smells High humidity Sump pump failure Water near the foundation

How we match the service to the problem

Six steps from symptom to defined work.

Water may travel before it becomes visible. We compare the affected area with accessible entry points, drainage, and exterior conditions.

STEP 01

Review the symptoms

Where does water appear, when does it happen, and does it follow rain?

STEP 02

Inspect accessible areas

Walls, floors, cracks, drains, pumps, and crawl spaces are checked where access allows.

STEP 03

Review exterior drainage

Grading, soil level, downspouts, patios, and surface drainage may be reviewed.

STEP 04

Trace the water path

We compare the wet area with possible entry points and collection routes.

STEP 05

Explain the options

We explain which service may fit the findings and what its practical limits are.

STEP 06

Define the work

The scope covers the work area, access, drainage route, and approved repairs.

Waterproofing services for Pasadena properties

Each property needs its own review.

Rainwater can move from roofs, driveways, patios, and higher ground toward a foundation. Water may also travel through soil and reach below-grade walls.

Neighborhood, building age, and foundation type alone cannot decide the correct system. Access, slope, drainage, and the actual water path matter.
