Avoid Wasting Time and Money

Your home is a complicated group of systems – heating, cooling, plumbing, electrical, roofing, siding, insulation, and many more.

If you want to solve a problem; pests, mold, roofs leaks, houses stay uncomfortable. Bad results happen despite many thousands being spent to “solve” problems.

Our goal is to help you solve problems while avoiding that frustration and wasted money. The complex but correct path is heavy up front on education. Then it requires careful planning. Some people have been told the “right” thing to do and heard so many conflicting opinions that they rightfully want to know not just what to do, but why.

Our efforts contradict a lot of the common myths perpetuated by people who don’t understand how the systems in your home are interconnected, and then explains why things need to be done. Much of it will be done with data and science.

Few of us have ever truly experienced living in a consistently pleasant comfortable home, but it is possible. No room in your home should be more than 2-3 degrees different from another. It shouldn’t have air that feels wet like a swamp or dry like a desert. The air shouldn’t feel oppressive to your sinuses or give you headaches. Nor should it smell. It should be the most comfortable house you’ve ever lived in. It should be so comfortable you never think about your comfort.

It’s a bit unsettling to hear, but studies and new measurement tools tell us our homes are often very unhealthy. High humidity levels can lead to dust mites and mold. Humidity also causes volatile organic chemicals in furniture and cleaners to release faster. These can lead to respiratory illness, allergies, asthma, etc. Appliances like gas water heaters and gas stoves emit bad things like carbon monoxide, particulates, and nitrous oxides. The air leaking into the house likely crept in through nasty places like the attic, garage, basement, crawlspace, or walls.

Liquid does the most damage, but water vapor is hard on things, too. The more moisture problems a house has, the more likely you are to need expensive repairs. If you design moisture management into your home, it is likely to be longer lasting, healthier, more comfortable, and less expensive to operate or repair. Crawl spaces won’t contribute to asthma issues. Termites won’t have wet wood to burrow into. Mold likely won’t develop or need to be treated.

This is generally what clients think of first. If you make a building really comfortable, healthy, and long-lasting, efficiency just follows. Saving Energy, Lowering Utility Bills and Rewarding yourself with a great living environment.


The first step of the process is to have our team thoroughly inspect your home inside and out, top to bottom. We check window and door frames, attics, ceilings, walls, heating and cooling systems, and more so that we can pinpoint the areas of energy loss.


We discuss our findings with you and we determine the best course of action to take to get all of the problems taken care of. This may involve the installation of new spray foam or cellulose insulation, replacement windows or doors, or we may need to seal your crawl space, as an example.


Next, we will make the repairs and improvements that you and our team have discussed. We will be sure that our experts are working with your family’s comfort and your home’s energy efficiency in mind.


Next, we will need to make sure that we perform our tests again to guarantee that the work we have done is effective. With our team, you can expect to get a great value for your dollar, and we are here to address any questions or concerns that you may have along the way.
