Energy Upgrades & Healthy Homes

Are you living with one of the EPA’s list of top five environmental threats to public health?

Are you sick of that musty smell wafting up from your basement – or sick because of it?  Indoor pollution levels are typically two to five times higher than those outside, and even if you’re adamant about maintaining a tidy, smoke-free home, moisture problems, poor ventilation, and contaminants can increase your risk of health problems from allergies and asthma to headaches, nausea, and worse. It’s no wonder that indoor air quality makes the EPA’s list of Top Five Environmental Threats to public health

Indoor air quality was also the focus of Ellen Tohn‘s presentation at the Affordable Comfort, Inc. New England Home Performance Conference.  “Weatherization and Home Performance will touch at least a million homes in the next decade,” said Tohn.  Integrating healthy home features into energy upgrades provides “the opportunity to make a huge difference for public health.

The EPA agrees: Integrated healthy home and energy efficiency upgrade activities can simultaneously lower utility costs and improve indoor air quality.”  Here’s how:

Keep pollutants out
In your living space, this means banning secondhand smoke and chemical-laden household cleaners, vacuuming and dusting regularly to eliminate pet dander and dust mites, and using carbon monoxide detectors to signal the presence of the poisonous gas.

Stop mold and mildew at their source
Damp, smelly basements are a breeding ground for mold and mildew.  If you’re tempted to close the basement door and try to forget about the petri dish beneath your feet, consider this:  you inhale almost 3000 gallons of air every day, and, thanks to the stack effect, most of the air in your home has passed through your basement. Whether the door is closed or not, your indoor air quality depends on having a dry, clean basement.  Basement encapsulation transforms damp, leaky basements into dry, healthy spaces – and research shows that moisture remediation lowers the risk of asthma by 33%.

Ventilate effectively
Your home depends on a slow, steady flow of air
.  The best way to ensure that a home is healthy, safe, and energy efficient is to pair air sealing with increased mechanical ventilation to make sure that air cycles in and out of the house at a healthy and consistent rate.

Get building science advice from an expert you trust
Unfortunately, the EPA has bad news, too: “Home energy upgrade activities might negatively affect indoor air quality if the appropriate home assessment is not made before work begins or if work is performed improperly.

The key to healthy, effective home performance upgrades is remembering that your house is a system.  You can’t change one part without affecting all the others, so enlist the advice of a trained building scientist before you start.

We are so pleased with the work the team from Evergreen Home Performance did in our home. The project included encapsulation of our basement with a reinforced vapor barrier, installation of a sump pump, spray foam insulation on the walls and insulation of the heating duct work. Everyone at Evergreen was friendly and professional. The project was completed on time and in budget. Our home is much cozier and warmer since the project was completed.

Evergreen did an amazing job insulating our historic home. Their professional staff worked hard to ensure the tough areas in the attic were covered, and clearly communicated their progress. We are seeing the results with our discounted heating bills. Thank you, Evergreen!

In the final stages of selling our home, and with a closing date set, an inspection came across an unanticipated issue in our attic. We quickly called in contractors, but nobody was able to identify the source of the problem. Then we thought of Evergreen. Brian Robinson was on site the next morning and immediately identified the source (a faulty roofing job completed three years earlier which had effectively sealed up portions of the ridge vent and restricted air flow - not easily visible with a quick inspection).

First we have Evergreen do a BIG project worth about $20K (windows, basement, insulate & rebuild an entire wall, a door, attics, and air sealing). They were so great we had them come back later when we decided we did want to do our other door. They are professional and do great work. They take care of your home and are trustworthy, and on top of all that friendly! I highly recommend you call them!

Very easy process, start to finish.  Friendly, professional, and really know their stuff.  They made some improvements to our condo and we were very happy with how it played out.  Would definitely recommend them.

We needed basement encapsulation to stop moisture coming up into the house from our regularly flooding basement. We had mold growing on windowsills and furniture. All the staff were friendly, respectful of our home, and easy to work with. Humidity has gone from 70% down to 40% and mold has not grown back after two months. Very grateful.

The Evergreen crew who installed insulation in my attic were fantastic! They were very professional, worked exceedingly hard, and they did an excellent job. They were very pleasant and friendly to be around. They cleaned up beautifully after each work day, and left my home in great shape on when they walked out the door for the last time. I can't believe they were able to accomplish all that they did with heat soaring into the 80s and 90s. It was pretty unbearable up there! They have my highest praise and my gratitude.

We had Evergreen energy do blow-in cellulose. I was very happy with the result. They tested with blower-door before and after. House is now MUCH warmer. Also, in the time since when I've had to open walls for various access, I've been impressed with how they got the insulation packed in everywhere. I'd use them again.

Great job installing windows and insulation.

Our house still the most efficient home we’ve ever lived in. And we have you folks to thank for that! A special howdy to Brian Robinson please!

Nothing but good things to say. The guys that came and did the actual work were extremely nice and did a great job. The energy audit was thorough and I was presented with multiple improvement options, I was even given ideas for improvement that Evergreen didn't offer. I never felt like I was being "sold".

Evergreen Home Performance shows its expertise from start to finish. Evergreen did three house projects in winter/spring/summer 2020 for me, attic insulation, crawl space under a porch insulation, and basement foam/vapor barrier. From my initial discussion with Bryan, I understood the reasons for choosing different types of insulation, the associated costs, and time estimates. Evergreen scheduled in advance, came when they said they would, and the crews were highly professional in their work and demeanor.

Awesome company. It was a few years ago that they did the audit and then we commissioned them to do the work. We subsequently sold our house and moved to South Africa, but their level of service and expertise will live on.

Working with Brian and with Nate and the rest of the crew was a pleasure. They made everything very easy and understandable. This was a major renovation and they were always at the ready with a lot of information. We had an extensive renovation on the basement which was a dirt basement and it came out beautifully. We can already tell from all of the insulation work what a difference it's made in sound and temperature. Brian worked with me on the rebates that are available when you do this kind of work. I would highly recommend this company to…

I had gotten estimates from several other companies, but Evergreen was in another league entirely with their professionalism. If you want the job done correctly, I couldn't recommend this company enough.
