Expectations of Buying a New Home

We all have expectations or should. We expect the sun to rise and set, the family to be content with what you have and the family’s health to be great, or at the least understood and getting better. We expect that if our kids are sick, they got it from someone at school. Personally, I like to blame my coughing, wheezing and sneezing on the walking petri dishes called grandkids. However, many times the coughing, wheezing and sneezing is to be blamed on an unhealthy home.

Interior vs. Exterior Probe Testing

There has long been a dispute as to whether moisture testing the external walls of a structure should be
performed from the interior or from the exterior.

Why Test a Home for Moisture?

We recently completed a survey of 1,938 homes we had probetested and analyzed for moisture intrusion, the majority of which had been built after mid-1980. The results are alarming. 63 percent of the stucco homes, 52 percent of the wood homes and 47 percent of the brick homes had structural damage – rotted wood – at one or more locations across the home.

The M-Word

What is the M-word? Most people reply, mold. Understandable considering mold is a common concern in the housing industry. Most folks don’t like to hear this, but the reality is that mold is everywhere, and unless you’re wearing a mask, you are breathing in mold as you read this article.

The Great Debate: Interior vs. Exterior Probe Testing

There has long been a dispute as to whether moisture testing the external walls of a structure should be performed from the interior or from the exterior. The nationally accepted practices favor exterior probe testing because water typically winds up on the exterior side of the wall cavity once it works its way into the system. However, there are many factors to consider when determining which testing approach to use on a given home.

Infrared: Truth Or Consequences

If you are a baby boomer or aficionado of old TV shows, you might remember the daytime television show “Truth or Consequences.” The show’s host would ask questions, and the contestant would have to correctly answer all of the questions or face having to perform a crazy act in front of a nationwide audience. Basically, if you didn’t know the truth, you would have to face the consequences.

How to Save a Sale

Everyone involved in a real estate transaction wants the deal to go through – preferably with as few speed bumps as possible. There are many factors that affect the facilitation of a sale – financing, restricted inventory, contingencies on other sales and a plethora of other possible points of contention. All of these are in addition to the potential of getting stuck in a traffic jam if issues are discovered during the inspections phase.

Gutters - It's That Time of the Year

It’s that time of the year again ... the hot humid days are replaced by cool dry breezes with nights free of biting bugs.

A View About Windows

Windows are, quite often, just accepted without question.  They came with the home.  It's not until the towel brigade is mopping up water from a closed window sill that homeowners begin taking a hard look at their windows in general.

2015 IRC Building Codes: Are We Doomed to Repeat History?

By now, everyone should be aware of the moisture problems that exist in homes, and especially in stucco-clad homes.  Our own testing shows that 90% of stucco homes built in the mid-80’s through the 90’s have major moisture problems causing structural damages that most people can’t even see. While construction practices and codes have improved over the last 15 years, the old adage “history repeats itself” comes to mind when reviewing what the new 2015 IRC Building Codes are requiring in new home construction in MN.
