Comprehensive Building Condition Assessments.

How much do you know about your home or office?
It's what you don't know that can hurt you, cost you, or even make you sick.



Thermal Imaging detects moisture.
Moisture is an enemy to your building, and your healthy indoor environment. Hidden moisture above ceilings, inside walls, and below floor finishes will provide a home for noxious molds and mildews.

Hidden moisture will also promote the premature decay and deterioration of your building's structure.

You may not be able to see a roof leak, a plumbing leak, a window wrap or a flashing leak until substantial damage has been done.

Predictive and Preventative maintenance can provide early detection of moisture, and that can help save you money, potential illness, and even costly and inconvenient litigation.



Thermal Imaging is non-invasive and non-destructive.

Thermal Imaging detects damaged, improperly installed and missing insulation.

Missing or damaged insulation can lead to condensation on living space surfaces that is conducive to mildew and mold growth.

You cannot tell how efficiently your existing insulation is performing by looking at it. Fourteen inches of blown in insulation with a high R-Value may look good, but in actuality it may be allowing cold air infiltration in winter, and hot air infiltration in summer.
Energy costs are rising and will continue to rise in the future. Updating your building's thermal efficiency has never been a better investment.



Thermal Imaging can detect overheated electrical devices that may create a fire hazard, or predict impending failure.

Thermal Imaging can evaluate subfloor heating systems for proper operation and defects, as well as traditional forced air, hot water, steam, and electrical radiant heat systems.

When central heating and cooling systems are not operating properly, it can lead to increased "plug load" because of fan and space heater use, leading to higher electric bills.

Many years of Thermal Imaging in the field has led to our ability to expect, discover and diagnose the causes of hidden conditions quickly.


What you can't see is important.

The cause of this leak in this multi-level home was a long flashing at a construction joint at the roof above. This was a substantial repair that cost over $2,700.00 to complete.


Sometimes plumbing fixtures leak.

It's always better to find out that a toilet is leaking before you have to repair and repaint the ceiling below it.  If a plumber can't see any damage, he could say it's not leaking.


40 year old hot water heat systems can start to leak.

The hottest spot is usually directly over or directly under the source of the hot water leak, making the repair as small as possible and the disruption to the building's occupants shorter.


Where was all of that hot water going?

The heating system had been leaking for years. No one could figure out where it was leaking. The only option was to run the entire heat zone overhead costing many thousands of dollars.


Cold walls make a good home for mold.

The ice damming may have happened many years ago, but the damaged insulation is going to continue to cause problems until it's fixed. Heat loss costs money and the cold surfaces host mold.


Damaged insulation in ceilings and side walls affects heating and cooling costs.

Sometimes the insulation is not complete before the drywall is installed through carelessness. Sometimes insulation gets wet and is degraded. It needs fixing.

When you buy, sell or maintain a property, it’s always a big deal.

All parties to a transaction (buyers, sellers, realtors, bankers, guarantors, etc.) and landlords and renters have a stake. That’s why you need to know who your inspector is working for.

When I am working for you, I am your advocate. I am not looking over my shoulder to see whom my report may have offended. My best interests must be your best interests.

In today's tough markets and with rising costs, you need every advantage you can get. So do I. That's why I carry a kit of high tech equipment to help me make sure that your interests are protected.

Whether you are buying or selling a property, let me help keep the unknowns to a minimum. Remember, what you don't know, can hurt you.

When I find deal breaking defects or defects that trigger price reductions in a building buying transaction, it almost always is the result of the Thermal Imaging process. I actually find more defects in new or newer buildings than in older ones, due to more prevelant poor construction practices.
