New article on gravity furnace inspection

October 13th, 2010

Every one in a while, you might run into a giant furnace with monstrous-looking ducts running in all different directions. These gravity furnaces, also known affectionately as “octopus furnaces”, use the force of convection to push air throughout a building. They lack the blower fan inherent to forced-air furnaces, which means they’re quieter and kick up less dust, but the benefits pretty much stop there. They are notoriously inefficient and most have outlived their life expectancies. To find out inspection tips and more, check out our new article on gravity furnace inspection.

New article on straw bale house inspection

October 12th, 2010

In the story of the Three Little Pigs, the wolf blows down a house of straw with ease. Modern straw bale houses, by contrast, can withstand high winds a whole lot better. They’re sturdier than most people realize, but they’re also more vulnerable to moisture than conventional homes. To find out more, check out our new article on straw bale house inspection.

New article on hand-dug well inspection

October 12th, 2010

The oldest wells were dug by hand, and this low-tech approach still survives today. Their construction is labor-intensive, but it requires few specialized tools. Inspection should be focused on features that keep children or animals from falling into the well, as they’re usually quite wide. A simple lid or stone wall usually does the trick. To find out more, check out our new article on hand-dug well inspection.

New article on anti-scald valves

October 9th, 2010

Anti-scald valves are designed to lessen the water temperature fluctuations in a building, which are an inconvenience and can potentially cause a person to suffer a burn or slip in the shower. They contain a special diaphragm or piston mechanism that  balances the pressure of the hot- and cold-water inputs, limiting one or the other to keep the temperature within a range of several degrees. To find out more about how they work and why they’re needed, check out our new article on anti-scald valves.

New article: Insulation R-Value

October 8th, 2010

Insulation sold in the U.S. is required to have an R-value assigned to it, but how are these ratings calculated?  Find out how R-values affect the energy efficiency of insulation — as well as why it won’t matter if the insulation is installed correctly but other building components are leaky — in Insulation R-Value.

New article: Low-E Windows

October 8th, 2010

Home inspectors know that a wide variety of windows is manufactured for increasingly specific installations.  Low-E windows are effective for blocking solar heat and the sun’s rays by reflecting them to keep heat in or out of the home or building, depending on the climate and application.  But consumers should be aware of some controversies surrounding these windows precisely because of their high-reflectivity properties that make them so efficient.  Read all about the benefits and potential problems in Low-E Windows.

New article: Solar Heat-Gain Coefficient Ratings for Windows

October 6th, 2010

As consumers search for the biggest bang for their energy-savings buck, windows take on special significance as an installation that must be as energy-efficient as possible.  Inspectors who perform energy audits can educate themselves and their clients on the importance of solar heat-gain coefficient (SHGC) ratings, especially because these ratings affect a window’s efficiency depending on the climate.  Read all about it in Solar Heat-Gain Coefficient Ratings for Windows.

New article on wildfire mitigation strategies and inspection

October 5th, 2010

As the most destructive wildfire in Colorado’s history tore through Boulder County last month, it should become more clear to homeowners, fire crews and inspectors that more emphasis should be placed on wildfire mitigation strategies. You might be surprised at just how many strategies are available, from custom window covers to vents that swell up and close when they’re heated, preventing stray embers from passing through them into the house. Inform yourself, check out our new article on wildfire mitigation strategies and inspection.

New article: U-Factor Ratings for Windows

October 5th, 2010

Understanding how to make a home more energy-efficient is a big priority for inspectors who perform energy audits, as well as for homeowners wanting to save on heating and cooling costs.  Ratings systems aid in making smart upgrades.  They’re also key in helping homeowners cash in on rebate programs.  Learn what U-factors are and how they are used to rate the energy efficiency of windows in U-Factor Ratings for Windows.

New article on PVC health hazards

October 5th, 2010

PVC is used everywhere in and around buildings, from sewage pipes and siding to shower curtains and junction boxes. It’s had a long and complicated history, but in recent years there’s been growing suspicion that PVC can vent toxic chemicals into indoor air and water. To find out more about PVC uses and its potential dangers, check out our new article on PVC health hazards.

New article on UFFI insulation inspection

October 1st, 2010

UFFI foam insulation was used extensively in North American homes during the 1970’s until it was banned due to fears over offgassing of formaldehyde. Those fears were largely unfounded and the ban was overturned in the U.S., although it still remains in effect in Canada. Learn the history of this insulation, why and where it was banned, and how to inspect for it in the home in our new article on UFFI insulation inspection.

New article on chimney collapse inspection

September 30th, 2010

Chimneys made from bricks or stone may look sturdy but few building components can crush a building so suddenly and without warning. Especially in seismically active regions, chimney inspection should be performed routinely to check for separation from the building, loose mortar, mechanical damage and undersized footings. To read more, check out our new article,  Chimney Inspection: Preventing Collapse
