Why Rain Leaks Cause Building Damage.

What kind of costly dangers can window and wall leaks bring to you and your building?

A lot of property managers see rain leaks as a temporary event happening in Southern California only a few times a year. And, mistakenly, their main remedy is just putting a bucket or towel to capture water dripping from window frames, walls, ceilings, and promising their tenants to somehow eventually fix it.

However, the problems caused by rain leaks are much more serious and eventually result in substantial damage to underlying structure of your building.

Water intrusion damage is considered the most common cause for expensive building repairs. In fact, based on insurance claim statistics, building owners in US spend billions of dollars each year, dealing with the consequences of water damage.

And if left unfixed, the damages will cost you thousands of dollars.

Rain water entering and penetrating through faulty windows and wall joints can result in the following problems:

Problem #1: Mold.

Not only mold can bring unpleasant look and odor, it can also cause serious health problems. Exposure to mold can lead to cough, nasal stuffiness, eye irritation and skin issues. Remediation procedures can turn out to be very expensive. That would also require to shut down the space for a few days or weeks.

Problem #2: Corrosion of structural beams.

Once a little rust settles in, the corrosion can be extremely costly to repair, and it becomes a serious safety hazard to the building’s occupants. Corrosion of structural beams can substantially weaken your building and cause rust staining on the exterior and interior.

Problem #3: Fire caused by the watered wiring.

When watered, wires can easily fry your appliances by causing power malfunctions and lead to property fire. Also, handling damaged wiring or failing to notice electrified tools, equipment, or standing water can severely injure your occupants and employees. And there are plenty of other various damages and threats that water leaks can lead to.

These costly problems should be enough reasons for you to get caulking for your property.

Exterior Caulking is critical for building health 

Exterior Caulking (link: ) serves as a powerful agent that blocks water, dust, sound and heat transmission through joints around windows, doors, trim, flashing, and other exterior building elements.

In addition, it allows joints movements within certain limits. Such movements caused by various factors including building settlement, earthquakes and, most commonly, heating and cooling of building exterior. In fact, building exterior expands when it’s under direct sun and heated, and shrinks when it’s cold at night time.

Besides of rain leaks prevention, exterior caulking is essential for maintaining temperature control inside a building. Waterproofed joints prevent heat from entering and cold air from leaving through the joints, and vice versa depending on outside temperature. Thus, it significantly increases energy efficiency and cost savings on electricity bills.

Lastly, in commercial settings, caulk greatly contributes to the appearance and value of your building. A proper caulking application by a caulking contractor can make your corners, slits, and joints look clean, attractive, and actually durable & sustainable.

Typical lifespan of any caulking sealant is between 5 to 10 years depending on the type of material, UV exposure, level and frequency of exterior joints deformation. However, caulk won’t last even a few months if it was applied incorrectly or wrong type of sealant was used.

The most common problems with exterior caulking are missed open joints, old sealant cracking, loss of adhesion and substrate failure (cracks). All of these problems except cracks, are fully preventable. That’s why it’s critically important to hire professional caulking contractor whether it install new caulking or identify leaking areas and fix them.

Typically, most of the leaks from frames & walls are caused by deteriorated sealant in leaking windows or wall joints. Such joints need to be thoroughly cleaned from old sealant, degreased, and re-caulked with the right products, compatible with the substrate, width of the joints, and overall environment.

Facade Waterproofing

Some walls are built from porous materials such as brick, natural stone and concrete. During strong rains, water can easily penetrate through, causing moisture and water damage inside your building. We provide commercial waterproofing by re-sealing wall joints and applying clear sealer (water repellent) to successfully prevent water penetration.
