My "little" family

First and foremost I am a family man. My wife and I have 8 amazing children. These guys & gals are the fuel that drive my long days.

I am a Certified Master Inspector that is licensed to provide services in Kentucky. My knowledge as a home inspector is based on 20 years of experience in the residential, commercial, and industrial construction industry and, over the past 10 years, I've inspected nearly 2000 homes. I am a Building Performance Institute certified Building Analyst. I have been certified by the Kentucky Ready Mixed Concrete Association. I designed and built both homes my family has lived in. Additionally, I am a Safety Specialist for the worlds largest online retailer. I have a passion for the work I do. I am able to use my skills and knowledge in each of these areas to provide an accurate, thorough, and unbiased inspection of your potential home. I follow the International Association of Certified Home Inspectors standards of practice, as well as the guidelines set forth by the state of Kentucky.

Well worn pouch

You don't buy them in the store this way. Years of use here.

I’ve watched the sunset on many job sites over the years. None which bring me more joy than when building for my family. When choosing your home inspector. Be sure they have experience in the building industry! I’ve built numerous houses over the years, two of those for my family. I have unlocked the front door on a whole lot more. In some of my busier towns, I can stand on the roof and count a handful of other roofs I’ve been on and can see. Having practical experience makes a huge difference in this profession.

are the best inspectors in the world. CMI is a professional designation available to all qualifying inspectors who wish to become Board-Certified by the Master Inspector Certification Board. All CMIs are experienced, dedicated to education, and have a proven record in the inspection industry.

Condensation is the accumulation of liquid water on relatively cold surfaces.

Almost all air contains water vapor, the gas phase of water composed of tiny water droplets. The molecules in warm air are far apart from one another and allow the containment of a relatively large quantity of water vapor. As air cools, its molecules get closer together and squeeze the tiny vapor droplets closer together, as well. A critical temperature, known as the dew point, exists where these water droplets will be forced so close together that they merge into visible liquid in a process called condensation.

Double-pane windows have a layer of gas (usually argon or air) trapped between two panes of glass that acts as insulation to reduce heat loss through the window. Other types of gas used in this space have various effects on heat gain or loss through the window. Some windows also have a thin film installed between panes that separates the space between the panes into two spaces, further reducing heat loss and heat gain through the window. If multiple-pane windows appear misty or foggy, it means that the seal protecting the window assembly has failed.

A desiccant is an absorbent material designed to maintain dryness in the space it protects. In a double-paned window, silica pellets inside the aluminum perimeter strip absorb moisture from any incoming air that enters the space between the panes. If not for the silica desiccant, any moisture in the space between the panes would condense on the glass as the glass cools below the dew point temperature.

Silica gel has an immense surface area, approximately 7,200 square feet per gram, which allows it to absorb large amounts of water vapor. As the sealant protecting this space fails over time, increasing amounts of moisture-containing air will enter the space between the panes, and the silica pellets will eventually become saturated and will no longer be able to prevent condensation from forming. A double-paned window that appears foggy or that has visible condensation has failed and needs to be repaired or replaced.

Although double-paned windows appear to be stable, they actually experience a daily cycle of expansion and contraction caused by thermal pumping. Sunlight heats the airspace between the panes and causes the gas there to heat up and expand, pressurizing the space between the panes. At night, the window cools and the space between the panes contracts. This motion acts like the bellows of a forge and is called thermal pumping.

Over time, the constant pressure fluctuations caused by thermal pumping will stress the seal. Eventually, the seal will develop small fractures that will slowly grow in size, allowing increasing amounts of infiltration and exfiltration of air from the space between the panes.

Windows on the sunny side of a home will experience larger temperature swings, resulting in greater amounts of thermal pumping, seal stress and failure rates.

Vinyl window frames have a higher coefficient of expansion resulting in greater long-term stress on the double-pane assembly, and a higher failure rate. Windows also experience batch failure, which describes production runs of windows, especially vinyl windows, that are defective, meaning that the pane assemblies have been manufactured with seals that have small defects that will cause the window to fail prematurely.

If it’s allowed to continue, window condensation will inevitably lead to irreversible physical window damage. This damage can appear in the following two ways:

riverbedding. Condensed vapor between the glass panes will form droplets that run down the length of the window. Water that descends in this fashion has the tendency to follow narrow paths and carve grooves into the glass surface. These grooves are formed in a process similar to canyon formation.

silica haze. Once the silica gel has been saturated, it will be eroded by passing air currents and accumulate as white “snowflakes” on the window surface. It is believed that if this damage is present, the window must be replaced.

Condensation is not always visible. If the failure is recent, a failed window may not be obvious, since condensation doesn’t usually form until the window is heated by direct sunlight. Windows in the shade may show no evidence of failure, so inspectors should disclaim responsibility for discovering failed double-paned windows.

Thermal Imaging as a Detection Tool

Under the right conditions, it’s possible to use an infrared (IR) camera to detect failed windows. IR cameras are designed to record differences in temperature.

InterNACHI provides a thermal imaging course that includes information on using IR cameras for this purpose, and has a message board forum devoted to IR.

Recommendations for Failed Windows

According to industry experts, the glazing assembly can be replaced approximately 75% of the time. Occasionally, the sashes must be replaced, and only about 5% of those cases require that the entire window be replaced.

Inspectors should be aware that there are companies that claim to be able to repair misty windows through a process known as “defogging.”

This repair method proceeds in the following order:

A hole is drilled into the window, usually from the outside, and a cleaning solution is sprayed into the air chamber.

The solution and any other moisture are sucked out through a vacuum.

A defogger device is permanently inserted into the hole that will allow the release of moisture during thermal pumping.

Inspectors should know that there is currently a debate as to whether this process is a suitable repair for windows that have failed, or if it merely removes the symptom of this failure. Condensation appears between double-paned windows when the window is compromised, and removal of this water will not fix the seal itself. A window “repaired” in this manner, although absent of condensation, might not provide any additional insulation. This method is still fairly new and opinions about its effectiveness range widely. Regardless, “defogging” certainly allows for cosmetic improvement, which is of some value to homeowners. It may also reduce the potential for damage caused by condensation in the form of mold or rot. Some skepticism exists about the effectiveness and cost effectiveness of this method of repair.

In summary, condensation in double-paned windows indicates that the glazing assembly has failed and needs repair or replacement. Visible condensation can damage glazing and is the main indication of sealant failure.
