Protecting Your Home's Exterior Masonry

The brick, stone, and block exterior of your home faces constant assault from the elements. Rain, snow, ice, and humidity work relentlessly to penetrate masonry surfaces, causing deterioration that worsens with each passing season. Bi-State Masonry, Inc. provides professional residential waterproofing services that protect your home's above-grade masonry from moisture damage. With over 26 years of experience serving homeowners throughout the Quad Cities, we understand the specific challenges our regional climate presents and deliver waterproofing solutions that work.

Many homeowners think of waterproofing only in terms of basement protection. While basement waterproofing addresses critical below-grade moisture issues, the exterior walls of your home need protection too. Brick facades, stone veneers, block walls, chimneys, and other above-grade masonry are all vulnerable to water penetration. Without proper waterproofing, moisture enters through porous masonry and deteriorated mortar joints, leading to efflorescence, spalling, freeze-thaw damage, and interior water stains. Our residential waterproofing services create a protective barrier that keeps water out while allowing your masonry to breathe.

Why Your Home's Masonry Needs Waterproofing

Brick, stone, and concrete block are durable materials, but they are also porous. Water can penetrate these surfaces and the mortar joints between them, especially as materials age and weather. In the Quad Cities, our climate makes this moisture penetration particularly damaging.

Freeze-Thaw Damage

The Quad Cities experiences roughly 100 freeze-thaw cycles each winter. When water enters masonry and then freezes, it expands with tremendous force. This expansion creates cracks, loosens mortar, and causes the face of bricks to spall (flake off). Each cycle compounds the damage from previous ones. Waterproofing prevents water from entering the masonry in the first place, stopping freeze-thaw damage before it starts.

Efflorescence

Those white, chalky deposits you sometimes see on brick walls are called efflorescence. They occur when water moves through masonry, dissolves soluble salts within the material, and deposits those salts on the surface as it evaporates. While efflorescence itself is primarily a cosmetic issue, it indicates that water is moving through your masonry—a problem that leads to more serious deterioration over time. Proper waterproofing eliminates the moisture movement that causes efflorescence.

Mortar Joint Deterioration

Mortar joints are typically more vulnerable to water penetration than the bricks or stones themselves. As mortar absorbs water and goes through freeze-thaw cycles, it cracks and crumbles. Deteriorated mortar joints allow even more water into the wall system, accelerating damage to both the mortar and the masonry units. Waterproofing combined with tuckpointing provides comprehensive protection for your walls.

Interior Water Damage

Water that penetrates exterior masonry doesn't just damage the masonry itself—it can migrate into your home. Homeowners often notice water stains on interior walls, peeling paint, or damp spots near exterior masonry walls. In severe cases, moisture intrusion leads to mold growth within wall cavities. Exterior waterproofing stops this moisture at the source, protecting both your masonry and your home's interior.

Preserving Property Value

Well-maintained masonry enhances curb appeal and protects property value. Stained, spalling, or deteriorating brick detracts from your home's appearance and signals deferred maintenance to potential buyers. Waterproofing is a relatively modest investment that helps preserve the beauty and value of your masonry for years to come.

Our Residential Waterproofing Services

Bi-State Masonry provides comprehensive waterproofing solutions for all types of above-grade residential masonry. We assess each home's specific needs and recommend the most appropriate approach.

Masonry Sealer Application

We apply professional-grade breathable sealers that penetrate masonry surfaces to create a water-resistant barrier. Unlike surface coatings that can trap moisture and cause damage, breathable sealers allow water vapor to escape from within the masonry while preventing liquid water from entering. This is essential for the long-term health of your brick, stone, or block walls. We select sealers appropriate for each masonry type and exposure condition.

Brick and Stone Waterproofing

Different masonry materials have different porosity levels and waterproofing requirements. Dense, hard-fired brick may need only a penetrating sealer, while softer brick or natural stone may benefit from a more robust waterproofing system. Our team evaluates your specific masonry and recommends products that will provide effective, lasting protection without altering the appearance of your home.

Chimney Waterproofing

Chimneys are particularly vulnerable to water damage because they're fully exposed to weather on all sides and experience significant temperature fluctuations. We waterproof chimney masonry with products designed for this demanding application. Chimney waterproofing is often performed alongside chimney restoration services for comprehensive protection.

Joint and Caulk Sealing

Water often enters wall systems at joints—where masonry meets windows, doors, trim, or other materials. We inspect these critical junctions and apply appropriate sealants to prevent water infiltration. Quality caulking at these transitions is an essential component of a complete waterproofing strategy.

Waterproof Coatings

In some situations, such as severely deteriorated masonry or walls with chronic moisture problems, a waterproof coating may be more appropriate than a penetrating sealer. These elastomeric coatings form a flexible membrane over the masonry surface that bridges small cracks and provides superior water resistance. We use coatings selectively where conditions warrant and always ensure proper surface preparation for lasting adhesion.

Preparation and Repair Work

Waterproofing is only as effective as the surface it's applied to. Before any sealer or coating application, we address existing damage. This may include tuckpointing deteriorated mortar joints, replacing damaged bricks, cleaning the masonry surface, and repairing cracks. Proper preparation ensures the waterproofing system bonds well and performs as intended.

Our Waterproofing Process

Professional waterproofing involves more than simply spraying a sealer on your walls. We follow a systematic process to ensure effective, long-lasting results.

Inspection and Assessment

We begin by thoroughly inspecting your masonry to identify existing damage, areas of water penetration, and conditions that affect product selection. We look for cracks, deteriorated mortar, efflorescence patterns, and other indicators of moisture problems. This assessment guides our recommendations.

Surface Preparation

Proper surface preparation is critical for waterproofing success. Depending on the condition of your masonry, preparation may include cleaning to remove dirt, mold, mildew, and efflorescence; repairing cracks and deteriorated mortar joints; and allowing adequate drying time. Sealers and coatings won't adhere properly or perform well on dirty, damaged, or wet surfaces.

Repair Work

If our inspection reveals damage that needs correction before waterproofing, we complete those repairs first. This often includes tuckpointing, crack repair, or brick replacement. Addressing these issues before waterproofing ensures you're protecting sound masonry rather than sealing in problems.

Product Application

We apply waterproofing products according to manufacturer specifications and industry best practices. Application methods vary by product type—penetrating sealers may be sprayed or rolled, while coatings are typically applied by brush or roller in multiple coats. We ensure complete, even coverage and proper application rates for optimal protection.

Quality Check

After application, we inspect the completed work to verify full coverage and proper application. We point out any areas that warrant monitoring and provide guidance on what to expect as the product cures.

When to Waterproof Your Masonry

Timing matters for waterproofing success. Here's guidance on when to consider waterproofing and when conditions are right for application.

Signs Your Masonry Needs Waterproofing

Consider waterproofing if you notice any of these conditions:

  • Efflorescence (white deposits) on brick or stone surfaces
  • Water stains on interior walls adjacent to exterior masonry
  • Damp or musty odors near exterior walls
  • Spalling (flaking) brick faces
  • Darkening of masonry during or after rain
  • Mold or mildew growth on exterior masonry
  • Deteriorating mortar joints

Proactive Waterproofing

You don't have to wait for problems to appear. Waterproofing new or well-maintained masonry prevents damage before it occurs. This is especially valuable for homes with south- or west-facing brick walls that receive heavy weather exposure, chimneys, and any masonry that's particularly exposed to the elements.

Best Conditions for Application

Waterproofing products require specific conditions for proper application and curing. Most products need dry masonry and moderate temperatures—typically above 40°F and below 90°F. Rain in the forecast can delay application, as can extremely humid conditions. In the Quad Cities, late spring through early fall generally provides the best conditions for waterproofing work. We schedule projects when conditions are appropriate and will postpone if weather doesn't cooperate.

How Often to Reapply

The longevity of waterproofing depends on the product used, exposure conditions, and masonry type. Penetrating sealers typically last 5-10 years, while elastomeric coatings may last longer. We recommend periodic inspection and reapplication as needed to maintain protection. We can advise on an appropriate maintenance schedule for your specific situation.

Frequently Asked Questions

What's the difference between residential waterproofing and basement waterproofing?

Residential waterproofing, as described on this page, focuses on protecting above-grade exterior masonry—brick walls, stone veneers, chimneys, and similar surfaces—from water penetration. Basement waterproofing addresses below-grade moisture issues, including water infiltration through foundation walls and floors. Many homes benefit from both services, as they protect different parts of the structure from different moisture sources.

Will waterproofing change the appearance of my brick?

Quality penetrating sealers are designed to be invisible once cured—they won't change the color or sheen of your masonry. Some products may slightly darken the surface temporarily during application, but this typically disappears as the product cures. Elastomeric coatings do change appearance since they form a visible film, but these are used selectively where conditions warrant. We'll discuss appearance expectations before any application.

How long does masonry waterproofing last?

Longevity depends on the product, exposure conditions, and masonry type. Penetrating sealers typically provide 5-10 years of protection, while elastomeric coatings may last 10-15 years or more. South- and west-facing walls that receive more weather exposure may need more frequent reapplication than protected surfaces. We can advise on maintenance intervals for your specific situation.

Can I waterproof masonry myself?

While consumer waterproofing products are available, professional application offers significant advantages. We assess your masonry condition and select appropriate products, complete necessary repairs before sealing, properly prepare surfaces, and apply products at correct rates for effective protection. DIY attempts often seal over damage that should be repaired or use inappropriate products that cause more harm than good.

Do you waterproof new construction?

Yes. Waterproofing new masonry before it's exposed to weather can prevent damage from ever occurring. New construction is actually an ideal time to waterproof, as the masonry is clean and undamaged. We work with homeowners and builders to protect new masonry from the start.

How much does residential waterproofing cost?

Cost depends on the area to be treated, masonry condition, product selected, and any repairs needed before application. We provide free estimates that detail the scope of work and costs. Waterproofing is generally a cost-effective investment that prevents far more expensive damage down the road.
