Masonry Cleaning & Sealing
Professional cleaning and sealing services that restore beauty, protect against staining and weather damage, and extend the life of your masonry.
Why Professional Masonry Cleaning Makes a Difference
Dirt, mold, algae, and pollution accumulate on masonry surfaces over time and ruin your property's appearance. What starts as minor discoloration gradually becomes thick buildup that makes brick and stone look old and neglected. This organic growth also holds moisture against masonry, which accelerates deterioration of both the surface material and mortar joints. Professional cleaning removes years of accumulated grime and reveals the original beauty of your masonry. The transformation often surprises homeowners who thought their brick or stone was just naturally dark or stained.
The wrong cleaning methods damage masonry permanently while amateur attempts often fail to remove stubborn staining. Pressure washing at high settings strips the protective fire skin from brick faces and erodes mortar joints. Harsh chemical cleaners etch stone surfaces and leave residues that attract more dirt. Paint and graffiti removers designed for other materials can discolor or dissolve masonry. We use appropriate cleaning methods matched to your specific masonry type, stain source, and desired results. This expertise prevents damage while achieving thorough cleaning that lasts.
Regular professional cleaning protects your masonry investment by removing contaminants before they cause permanent damage. Algae and moss growth appears harmless but their root systems penetrate mortar joints and create pathways for water intrusion. Efflorescence indicates water movement through masonry that will worsen if not addressed. Paint overspray, rust stains, and mortar smears become harder to remove the longer they remain on surfaces. Cleaning every few years maintains appearance and prevents minor issues from becoming major restoration projects. Visit our home page to learn about our complete masonry maintenance services.
Masonry Problems We Clean and Remove
- Dirt, dust, and pollution buildup that dulls masonry appearance
- Algae, mold, and moss growth causing green or black staining
- Efflorescence showing as white powder or deposits on surfaces
- Rust stains from metal fixtures, railings, or lawn equipment
- Paint splatters and graffiti requiring specialized removal
- Mortar smears and construction residue from installation
- Oil and grease stains on driveways and garage areas
- Hard water deposits and mineral staining near irrigation
Safe, Effective Masonry Cleaning Techniques
Chemical cleaning uses specialized solutions formulated for specific stain types and masonry materials. Acidic cleaners dissolve mortar residue and mineral deposits but require careful application and thorough rinsing to prevent surface etching. Alkaline cleaners work better for organic stains and general dirt without the risks of acids. We test cleaning solutions on inconspicuous areas first to verify they work safely on your specific masonry. Multiple applications with dwell time often work better than single aggressive treatments that risk damage.
Low-pressure washing combines mild chemical cleaning with water rinses that remove dirt without damaging surfaces. We use pressures appropriate for the masonry type, typically under one thousand PSI for most residential applications. Brick can tolerate slightly higher pressures than soft stone. The nozzle angle, distance from surface, and water volume all affect cleaning effectiveness and safety. Proper technique requires training and experience that most homeowners and general contractors lack. Poor pressure washing damages more masonry than any other DIY maintenance attempt.
Manual cleaning methods work best for delicate historic masonry or situations where other methods pose risks. We use soft brushes with appropriate chemical cleaners applied by hand to gently remove staining without mechanical damage. This labor-intensive approach takes longer but protects irreplaceable historic materials. Poultices draw stains out of porous stone using absorbent materials saturated with cleaning solutions. The poultice sits on stains for hours or days, then gets removed along with the dissolved staining. This method works particularly well for deep oil stains in stone.
Post-cleaning treatment neutralizes any chemical residues and prepares surfaces for sealing if desired. Thorough rinsing removes cleaning solutions that would otherwise remain in masonry pores and cause future problems. We inspect mortar joints after cleaning and recommend repointing if deterioration is visible. Sometimes cleaning reveals damage that was hidden under dirt, which gives you the opportunity to address problems before they worsen.

Protecting Your Masonry with Professional Sealing
Masonry sealers create protective barriers that repel water while allowing moisture vapor to escape from within the masonry. This breathability is critical because trapped moisture causes more damage than exposure to weather. Quality sealers prevent water absorption that leads to freeze-thaw damage, efflorescence, and staining. They also make future cleaning easier because dirt and organic growth cannot penetrate sealed surfaces as readily. Not all masonry needs sealing, but when appropriate, sealers provide excellent protection with minimal visual impact.
Different sealer types serve different purposes and masonry materials. Penetrating sealers soak into masonry pores and provide protection without changing appearance. Film-forming sealers create surface coatings that offer maximum protection but may alter color or add sheen. Some sealers enhance colors to make masonry look wet or darker, while others remain invisible. We recommend sealer types based on your masonry material, exposure conditions, and appearance preferences. Application timing also matters because sealers need clean, dry surfaces to bond properly.
Sealing frequency depends on sealer type, exposure, and traffic levels. Most quality sealers last three to seven years before reapplication becomes necessary. Horizontal surfaces like pavers and patios need more frequent sealing than vertical walls because they take more abuse from weather and traffic. We can assess your existing sealed surfaces and determine if resealing is needed or if the current protection remains adequate. Over-sealing wastes money and can trap moisture if old sealer layers prevent proper breathing.
The sealing process requires proper surface preparation including thorough cleaning and complete drying. Sealing damp masonry traps moisture inside and causes problems rather than preventing them. We wait for ideal weather conditions with appropriate temperatures and low humidity for sealer application. Multiple thin coats applied properly provide better protection than single heavy applications. The finished result is masonry that resists staining, sheds water effectively, and maintains its appearance far longer than unsealed surfaces.
