Indoor Air Quality & Healthy Homes

Back to Blog

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.

The EPA has good news for homeowners concerned about indoor air quality and energy efficiency: 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.

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.  Evergreen Home Performance offers comprehensive, whole-house improvements, including insulation, air sealing, basement encapsulation, and other energy-smart services.  Typically, our customers see a 25-50% reduction in their overall energy use, and a 10% return on their investment.  Contact Evergreen Home Performance for your FREE energy-smart consult at 207-594-2244 to find out how we can do the same for you!

Evergreen did a fantastic job replacing 28 windows in our house. They were friendly, courteous, and very detail oriented. Brian did a great job planning, estimating and executing the project. Our energy use has dropped significantly since the work was done.

The Evergreen team was amazing from initial assessment and planning to the crew that came to complete the work. Our basement encapsulation is the best money we've spent on our house by far. The work was thorough and high quality. And what a wonderful group of people to work with. I highly recommend Evergreen!

Bryan, Dave and the entire Evergreen team are wonderfully professional, prompt and thorough. I enjoyed working with them and look forward to continued work as we upgrade our home! Thank you so much for your professionalism, fairness, time and diligence.

Professional, friendly and hard-working staff. The product/approach they use for insulation is top notch. We felt the difference immediately, both from added warmth and eliminating drafts. The team and management were easily available to answer our questions or coordinate meeting times. Highly recommended.

A thorough inspection of our (older) house and its energy needs. Competent and personable work crew.

Jacob Watson

We just finished a large project of air sealing and reinsulating our 1890s basement and attic which had been completely renovated 8 years ago but still felt cold and lacked proper energy assessment and corrections. We met with Justin in December and were very impressed with his knowledge, professionalism and communication skills and knew Evergreen was who we wanted to work with. Dave was our on hands project manager and was excellent. The office staff has been quick to respond and helpful as well when needed.

Great team!

Thorough, smart, informative, integrated, and communicative -- that's how my experience was with Evergreen even with the covid interruption midstream. The team picked up where they left off, insulated basement and air sealed attic and knee wall in 100' temps under the eaves! This business group was a pleasure to work with.

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".

Ryan Adams

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).

I never leave reviews, but had a great experience with Evergreen and wanted to spread the word! In short, we worked with them to insulate our roof this winter and have noticed surprising immediate results. The constant ice dams I have wrestled with are completely gone, and the home is noticeably more comfortable. It's a little too early to tell if our oil bill is going to reduce, but I imagine we will see an impact there as well.

This team of individuals was professional at all times. They set up barriers that kept the dust at a minimum. They conducted an air flow audit and cut the draft circulation from the outside in half by sealing cracks. They hauled out the old insulation and replaced it with blown in insulation with an R - 60 Value. They also did the rebate paperwork so that I could get my $1500.00 rebate from the state of Maine. I highly recommend Evergreen Home Performance!

Evergreen removed and replaced the insulation in my attic. They did a great job!, Crew was excellent, and the whole thing went smoothly, and the attic was NOT easy to get into or work in, so kudos to some hard work done well!

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…

Working with Evergreen was a dream! Professional, knowledgeable, and super clean work. Communication was fast and service impeccable. The bedroom floors in our 1960's split ranch will be warm with the new insulation between them and the garage. Bring on the snow! (not really, but sort of)
