What You Should Know About Waterproofing Your Home or Business

Mar 24, 2025 | Waterproofing

Winter in the Pacific Northwest can bring drenching rains, sudden downpours, and near-constant dampness. While it’s no secret that extra moisture can wreak havoc on homes and businesses, many property owners remain unsure about where leaks originate and how best to prevent or fix them. If you’ve noticed water seeping into a basement corner, a leak staining your ceiling, or unexplained dampness near windows, it might be time to consult a professional. After all, water can travel surprisingly far from its actual entry point before it becomes visible—sometimes, what you see inside is just the tip of the iceberg.

Below, we’ll explore what you should be aware of when it comes to waterproofing, especially during the high-rain seasons. We’ll also walk through the process Rock Solid Waterproofing uses to identify and address leaks for both residential and commercial properties. You’ll learn why on-site inspections are so crucial, why water can travel in mysterious ways, and how a carefully coordinated approach can safeguard your home or business from escalating (and expensive) water damage.

The Surprising Ways Water Travels

One of the biggest reasons homeowners and business owners struggle with leaks is the misleading nature of water’s path. Seeing water drip from one specific spot in the interior can be deceiving, because it doesn’t necessarily mean the leak is coming from that exact location on the outside. Water can seep in through even the smallest gap—be it a hairline crack in your foundation or a hidden void in the siding—and then move along structural components, using capillary action to traverse a considerable distance.

Capillary action refers to water’s ability to move through narrow spaces (like the pores in concrete or small seams in wood), often defying gravity and common sense. You might see water stains low on a basement wall, for instance, when the actual point of entry is several feet away. Similarly, a leak in your roof could end up trickling down inside a wall cavity before ultimately showing up on the first floor. Winter weather intensifies these issues because water is both abundant and persistent, repeatedly testing every weakness in your building’s envelope.

Common Weak Points to Look For

  • Foundation Cracks
    Even minor cracks can allow water to enter at ground level. In older buildings, mortar joints or settling cracks are prime culprits.
  • Deck and Balcony Seams
    Elevated decks, balconies, or patios can experience leaks that ultimately affect interior spaces. The joints where the deck connects to the main structure are often problematic.
  • Roof Flashing
    Flashing is designed to protect areas where the roof intersects chimneys, vents, or walls. If it’s improperly installed or deteriorating, water can funnel inside.
  • Window and Door Frames
    Tiny gaps around frames can let moisture sneak in, leading to rot, mold, or even interior water stains.
  • Gutters and Downspouts
    Clogged or damaged gutters and downspouts can overflow, causing water to pool around the foundation or on decks, eventually leaking inside.

Why an On-Site Inspection Is Essential

Given the many ways water can hide its trail, a simple phone consultation rarely suffices. What’s needed is an on-site visit from a trained professional who knows how to trace water infiltration to its true origin.

  1. Direct Observation
    A waterproofing expert will look for telltale signs—discolorations, soft or warped materials, musty odors, or rust on metal components—that indicate the path water has taken.

  2. Moisture Meter Readings
    Professionals may use tools like moisture meters or thermal imaging to detect elevated moisture levels behind walls, under floors, or near suspect areas.

  3. Structural Assessment
    A knowledgeable inspector can identify issues with grading, slope, or structural weakness that encourage water to pool or move in unexpected ways.

  4. Tailored Recommendations
    Every leak situation is unique. After identifying the source, an expert can recommend a solution specifically geared to your property—whether it’s sealing a foundation crack, waterproofing a deck, updating flashing, or installing a basement drain system.

How Rock Solid Waterproofing Responds to Calls

If you suspect a leak or want to prevent potential water damage, here’s a snapshot of how Rock Solid Waterproofing handles incoming inquiries:

  • Initial Phone Call
    Customers reach out to the office, which is staffed with a live person from 8:00 AM to 5:00 PM. This ensures you can speak directly with someone about your concerns, rather than leaving a voicemail. The office staff gathers basic details, like the nature of the leak, any visible signs, and your location.

  • Appointment Scheduling
    Based on your availability and the urgency of the situation, the office sets up a time for one of the sales reps to visit your property. These sales reps aren’t just salespeople; they have hands-on experience with waterproofing and can accurately assess problem areas.

  • On-Site Inspection (30–60 Minutes)
    The sales rep arrives at your home or business, ready to listen to your history of the problem—such as how long the leak’s been occurring, what you’ve tried so far, and any unusual factors you’ve noticed (like increased staining after specific storms). They’ll measure the space, check potential entry points, and discuss possible solutions.

  • Bid and Proposal Preparation
    Once the inspection is done, the rep heads back to the office to work up a formal bid. This proposal details the scope of work, recommended materials, and estimated costs. You receive it for approval, and if you decide to move forward, the scheduling team arranges your project date.

What to Expect During an On-Site Consultation

Below are elements commonly assessed during a typical inspection:

  • Exterior Condition
    A rep may walk the perimeter of your property, examining the grade of the soil, looking for standing water near the foundation, and noting the condition of gutters, downspouts, and any visible cracks.
  • Interior Structures
    If you have a basement, they’ll check the walls, floors, and any existing waterproofing measures. For upper-level decks, the rep looks for signs of water intrusion below the structure—like water stains on ceilings or interior walls.
  • Moisture Levels
    Where needed, non-destructive tools can pinpoint areas where water is present just behind the surface.
  • History and Patterns
    The professional will want to know if the leak worsens after certain types of rain (like heavy downpours versus light but prolonged drizzles), if there’s any correlation with melting snow, and whether you’ve noticed dampness in other parts of the property.

After reviewing these details, they’ll craft a solution that addresses not just the leak itself but also the root cause—so you won’t have to call again for the same issue down the road.

Why Quick Action Matters

A water leak might seem like a minor annoyance at first, but the longer it goes unaddressed, the more significant the potential damage:

  • Structural Deterioration
    Wood framing can rot, metal beams can rust, and concrete can weaken. Over time, compromised structural elements can lead to safety hazards.
  • Health Concerns
    Moist, enclosed environments breed mold and mildew. Spores can affect indoor air quality, aggravating allergies or respiratory conditions.
  • Escalating Repair Costs
    A small leak is often cheaper to fix than a major water intrusion that’s allowed to fester. Once mold spreads or wood rot sets in, remediation costs can skyrocket.

To avoid these pitfalls, swift diagnosis and repair are essential. Winter months bring heavy, continuous rain, so even a small crack can lead to substantial infiltration if not promptly remedied.

Tailored Solutions for Every Water Problem

Rock Solid Waterproofing, like many reputable waterproofing services, understands that no two properties are alike. Variables such as soil composition, house age, foundation design, and local climate all affect how and where water enters. Possible solutions might include:

  • Foundation Sealing or Exterior Membranes
    If the water infiltration is occurring at or below ground level, an exterior membrane or sealant may be applied. Some cases also require excavation to expose exterior walls, making sure any cracks or gaps are sealed comprehensively.

  • Basement Waterproofing Systems
    For below-ground spaces, an interior drainage system (such as a perimeter drain leading to a sump pump) might be the best fix. This collects water before it seeps into living areas and safely diverts it outside.

  • Deck and Balcony Waterproofing
    Elevated structures can be sealed with specialized, multi-layer systems like Westcoat, which use acrylic cements to form a highly durable, flexible waterproof barrier.

  • Roof Flashing Replacement
    Sometimes the culprit is substandard or deteriorating flashing around chimneys, skylights, or vent pipes. Upgrading this flashing can prevent water from sneaking under shingles and traveling down interior walls.

Making the Most of Your Consultation

Here are a few tips to optimize your inspection visit and ensure your waterproofing plan is both comprehensive and cost-effective:

  • Keep a Record
    Note when you first noticed the leak, how it appears during heavy vs. light rain, and if you’ve noticed any patterns (like leaks occurring only when wind blows from a certain direction). These details help the inspector piece together the water’s path.

  • Ask Questions
    Don’t hesitate to get clarification on proposed solutions, recommended materials, or whether you need additional measures like gutter repairs or landscaping adjustments.

  • Discuss Budget and Timeline
    Waterproofing can range from a minor patch job to a full excavation and membrane replacement. Be clear about your budget constraints so the professional can tailor their proposal accordingly. Also, ask about the expected duration of work and if any parts of your home or business will be off-limits during that time.

Preventive Steps You Can Take Year-Round

While professional waterproofing is the ultimate safeguard, there are some preventive actions that help minimize the risk of leaks:

  1. Regularly Clean Gutters
    Keep gutters and downspouts free from leaves and debris so rainwater flows freely away from the foundation.

  2. Check Outdoor Grading
    Make sure the ground slopes away from your building. Flat or reverse-graded lawns can pool water near the foundation.

  3. Address Cracks Quickly
    Keep an eye on your basement walls, interior ceilings, and any masonry. Promptly reseal or repair any fissures before they expand under pressure from rain or freeze-thaw cycles.

  4. Trim Trees and Shrubs
    Vegetation growing too close to the house can funnel water onto walls or block sunlight, slowing evaporation. Overgrown trees can also drop limbs or leaves that clog gutters.

  5. Review Roofing
    Regularly assess shingle condition and flashing, particularly after storms. A small roof leak can gradually become a big problem.

Benefits of Proactive Waterproofing

When water is kept in check, your home or business gains:

  • Increased Property Value
    Potential buyers or investors appreciate a secure property that doesn’t have a history of water issues.

  • Better Indoor Air Quality
    Reducing dampness curbs mold growth and helps maintain a healthier environment.

  • Longevity of Structural Elements
    Protected foundations, framing, and other building materials last longer, helping you avoid premature replacements.

  • Peace of Mind
    The reassuring knowledge that your property can handle the worst of winter’s deluges without unwelcome surprises.
