Many building interior moisture intrusion issues are attributed to sheet metal failures. The primary cause for this condition is failed caulking joints. There are several reasons why these joints fail, such as inadequate attachment to the sheet metal components to adjoining surfaces such as walls, chimneys and other vertical or horizontal surfaces. Inadequate attachment relies on the caulking to keep these areas attached to each other or to surface they are mounted to, thus stressing the caulk beyond its limitations that it was intended to perform to.

Another reason that caulking joints fail is due to the application of the caulk itself. In many instances the sheet metal joints are surface sealed. This condition leaves the caulk exposed to the elements; this accelerates the deterioration of the caulk. Thermal expansion and contraction of sheet metal components and adjoining surfaces will also stress caulking beyond its limitation when only applied to the exterior surface of the joints.

For sheet metal components to perform in a satisfactory manner they must be properly lapped with caulk in between the joints, provided with proper attachment methods to the surfaces they are mounted to with acceptable interfacing to exterior cladding systems of the structure.

In some instances caulk must be applied in an exposed manner such when installing counter-flashing systems to masonry or structural concrete. With this type of application, the exposed caulking should be inspected periodically by a qualified waterproofing professional to make sure that caulking is performing as intended and to maintain the waterproofing integrity of the structure.

Waterproofing protects your home from allowing water and moisture from getting in where it doesn’t belong. But it is not just wetness you’re protecting your home against. There can be serious long-term ramifications from improper waterproofing.

Heavy rain, runoff, poorly placed gutters and many other factors may allow water to accumulate in the soil, creating hydrostatic pressure over time. This accumulation can cause the foundation to crack and leak and may cause electrical hazards, mold and mildew growth, insect problems and structural damage to your property.

Waterproofing is an extensive term and includes the application of coating systems, caulking, and sealants. They all play an intricate part in protecting your property and keeping it air and water tight.

There are an assortment of coating systems, caulking and sealants which help safeguard your exterior walls, concrete floors, windows and water features from moisture, chemicals, and heat and freeze-thaw damage. Many applications are ENERGY STAR® rated and come in a variety of colors, styles and textures which can be customized specifically for your decorative and architectural needs.

It is recommended to allow a professional to fill your waterproofing needs. They are trained to detect any unforeseen problem areas that others may not be able to identify.  This preventative maintenance can help to ensure your family and your home is properly protected for years to come.

Caulking is a form of waterproofing which is essential for keeping your home safe. Not only is it crucial on the inside but also as protection from the elements and other intrusions from the elements and other intrusions from the outside.
 
Think of caulking as putting a force field around your property. This force field protects your home by seaming joints and cracks. Caulking stops insects from getting in where they don’t belong, and that’s just scratching the surface of the many benefits of having your home properly caulked. Here are a few additional benefits:

• Save on cooling and heating costs
• Improve property value
• Improve living conditions
• Prevent moisture and mold from developing
• Prevent possible structural damage

Caulking IS green. By sealing your home and keeping cool air inside in the warmer months and out in the cooler months, your home is more energy efficient.

It is recommended to hire a professional to fill any waterproofing or caulking needs you may have. They are trained to detect any unforseen issues that others may not be able to identify. This preventative maintenance can help ensure your family and home is properly protected for years.
