What areas need masonry waterproofing?

The foundation of your house is the primary structure that requires effective waterproofing. By applying specialized techniques and materials, we ensure that your foundation remains secure and protected against moisture infiltration.

Basement Walls

Basements are particularly susceptible to water seepage due to their below-ground level. Sealing/ waterproofing creates a barrier that prevents water penetration, keeping your basement dry and free from issues such as dampness, mold, and mildew.

Exterior Walls

The exterior walls of your house are constantly exposed to the elements. Waterproofing these walls is crucial to prevent water from seeping through the masonry, which can lead to structural damage and interior moisture problems.


Chimneys are highly vulnerable to water damage due to their vertical positioning and exposure to rain and other weather conditions.

Waterproofing ensures that your chimney remains protected, preventing water infiltration and potential issues such as brick deterioration and interior leaks.

Retaining Walls

Retaining walls provide structural support and prevent soil erosion. Waterproofing these walls is essential to maintain their integrity and prevent water from compromising their stability.

Crawl Spaces

Crawl spaces are often overlooked but require proper waterproofing to prevent moisture buildup and the associated problems, such as mold growth and wood rot. Our waterproofing solutions help keep crawl spaces dry and protected.

Waterproofing the foundation is crucial because it serves as the base and support for the entire structure, damage to which can compromise their structural integrity.

By keeping the foundation dry, it reduces the risk of cracks, shifting, and settlement, ensuring the stability and longevity of the building.

Basement Walls

Basements are below ground level and are more susceptible to water intrusion due to hydrostatic pressure and poor drainage.

Waterproofing basement walls prevents water seepage, which can lead to basement flooding, dampness, and the growth of mold and mildew. It helps maintain a dry and usable space, protecting valuable belongings and preventing damage to the foundation.

Interior Walls

Interior walls, particularly those in areas prone to moisture, such as bathrooms, kitchens, and laundry rooms, require waterproofing to prevent water damage.

Waterproofing interior walls creates a protective barrier that prevents water from infiltrating the wall materials, reducing the risk of deterioration, mold growth, and costly repairs.

Exterior Walls

Exterior walls are constantly exposed to the elements, including rain, snow, and fluctuating temperatures. Waterproofing exterior walls helps prevent water penetration, which can cause structural damage and degradation of building materials.

Additionally, by waterproofing you can also maintain higher energy efficiency of the building as it prevents water infiltration and subsequent heat loss.


Chimneys are exposed to the elements, making them highly vulnerable to water damage. Waterproofing the chimney is necessary to protect it from water infiltration.

Moisture can deteriorate the chimney structure, leading to cracks, spalling, and the potential for collapse. Using specialized sealants and coatings creates a barrier that prevents water penetration, extending its lifespan and ensuring its safe operation.

Retaining Walls

Retaining walls are designed to hold back soil and prevent erosion. Waterproofing these walls is crucial to maintain their structural integrity and longevity.

Without proper waterproofing, moisture can seep into the retaining walls, causing soil expansion, cracks, and damage.

Crawl Spaces

Crawl spaces are typically located beneath a house and often suffer from excess moisture. Without proper waterproofing, crawl spaces can become damp and susceptible to mold growth, wood rot, and structural damage.

Waterproofing the crawl space helps prevent moisture infiltration, creating a dry and healthy environment.

It also contributes to improved indoor air quality and helps protect the structural integrity of the house by preventing issues like rotting floor joists and mold-related problems.

Where do you need caulking repairs/ services?

Windows and Doors

Caulking around windows and doors helps create a tight seal, preventing drafts, air leakage, and moisture infiltration. It improves energy efficiency and enhances indoor comfort.

Caulking is applied at all joints where two or more of different materials or buildings meet. This helps create a watertight seal, preventing water from seeping into the gaps and potentially causing damage to the inside of the building.

Shelf Angles

A shelf angle is most of the time a structural steel member that supports and transfers the dead load of the outer brick wythe back to the building frame. Commonly detailed on masonry-clad buildings, these horizontal steel angles are attached to the frame at vertical intervals.

These need flashing and caulking maintenance over the years.

Metal Panels

New to architecture, metal panels now are being used at a greater pace. These panels many times rely on caulking to keep the members watertight. Once the caulk begins to wear, it’s time for a review and possible removal and replacement of the caulking.

This prevents water from infiltrating the gaps and ensures a tight seal, reducing the risk of water damage and maintaining the overall integrity of the exterior.

Gaps and Cracks

Caulking is effective for sealing gaps and cracks in walls, ceilings, and floors. It prevents air leakage, water intrusion, and the entry of pests or insects.

Exterior Joints

Exterior joints, such as where different materials meet (e.g., siding and trim), may require caulking to seal gaps and protect against weather elements. Proper caulking helps prevent water intrusion, air leakage, and potential damage to the building.

Expansion Joints

In large structures or areas where there is expected movement or expansion, caulking is applied to expansion joints. These joints allow for thermal expansion and contraction while maintaining a watertight seal.

Concrete Cracks

Caulking is often used to seal cracks in concrete surfaces, such as sidewalks, driveways, and parking lots. It helps prevent water from entering the cracks, minimizing further deterioration and extending the life of the concrete.

HVAC Penetrations

Caulking is applied around HVAC (Heating, Ventilation, and Air Conditioning) penetrations, such as pipes and vents, to prevent air leakage and maintain energy efficiency.

Why do you need caulking repairs/services?

Caulking serves several important functions in building maintenance and construction:


Caulking creates a tight seal between two surfaces, such as joints, gaps, or cracks. It fills in voids and prevents the infiltration of air, water, or pests. By sealing these openings, caulking helps maintain the integrity of the structure and enhances energy efficiency.

Draft and Air Leak Prevention

Caulking is effective in reducing drafts and air leakage in buildings. By sealing gaps and cracks, it prevents the exchange of indoor and outdoor air. This improves the energy efficiency of the structure by reducing heat loss in winter and heat gain in summer, leading to lower energy bills.


Caulking can contribute to sound insulation by sealing gaps in walls, floors, and ceilings. It helps reduce the transmission of noise between rooms or from outside sources, enhancing acoustic comfort within the building.

Aesthetic Enhancement

In addition to its functional benefits, caulking also provides a finished and polished appearance. It can be color-matched to blend seamlessly with the surrounding surfaces, improving the overall aesthetic appeal of the space.
