What Is That Musty Smell in the Basement?

Back to Blog

Mainers spend half of the year waiting for winter to be over. When the spring temperatures finally do arrive, and sundown shifts to a reasonable hour, it can feel like a whole new state! But when those musty and moldy smells return to your home along with the warm spring weather, you may be feeling thankful it is warm enough to stay outside where you can avoid it. 

So what is it that causes these unpleasant odors to eminate from your Maine home, and how can you get rid of them? The short answer is — it’s moisture, and fixing it will require improving your home’s overall performance. Here’s what you need to know. 

The Causes of that Musty Smell

Musty odors happen when moisture accumulates inside your home, allowing mold and mildew to grow. This mold and mildew might not always be visible to you or your family members — it can hide behind your drywall, in the wood under your floors, or just about anywhere else.

Moisture itself generally accumulates most often in a basement or crawlspace. So why does that smell seem to find its way into other areas of your home? The reason for this is an imprtant building science principle called “the stack effect”. 

How a Wet Basement Makes for a Musty Home

Ideally, your home would have a near-airtight seal, keeping outside air out and your conditioned indoor air in as much as possible. However, there are often hidden air leaks throughout the home that can cause air to freely move in and out.

Air leaking into your basement is laden with moisture. As it warms, it moves up throughout your home toward the attic in what’s called the “stack effect”, where it escapes through the holes in your attic. Once there is moisture in your basement, mold and mildew conditions are created, and the continuing stack effect will bring that musty, smelly, and unhealthy air up into the rest of your home, reducing your indoor air quality and stinking up your living space. 

Fix Your Damp Basement, Fix the Must and Mildew!

If you are looking for a solution for your mold concerns,and the foul odors coming from the area under your home, it all starts by controlling the moisture in your basement.! At Evergreen Home Performance, we encapsulate the entire basement using vapor barrier installation, air sealing and insulation to ensure it is airtight and fully insulated. 

Basement encapsulation provides more benefit than just “stopping the stink”. Homeowners will also notice:

  • A more comfortable home, year round

  • Fewer mornings with cold floors

  • Reduced need for your heating and cooling equipment

  • Reduced indoor drafts

While the basement is like ground zero for moisture and mold problems, the rest of your home should be addressed as well in order to resolve any issues above the basement that are exacerbating the problem. With an energy audit, Evergreen Home Performance can give you a look into how your entire home is performing, and how we can upgrade your home for reliable comfort, health, and energy savings.

We had a fantastic experience working with Evergreen to insulate our roof this winter. Everyone was extremely friendly throughout the process - the crew at our home worked hard, were approachable with questions, and the team leader even showed me around the project to point out specific areas they were working to improve.

The crew members from Evergreen Home Performance each made sure to greet us every day, while maintaining their distance in this time of the pandemic. Their work took a total of nine days, spread over three weeks. Even though they were working in multiple rooms of our house, as well as the basement and attic, they were unobtrusive and always cleaned up after themselves every day. The on-sight manager kept us informed of their daily schedule so we'd know which parts of the house they'd be working on.

I would recommend Evergreen wholeheartedly because of their professionalism, their follow through, and thoughtful project planning.

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)

Jess Dee Proctor

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.

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!

Last week, my oil company asked if we were using some other kind of fuel because our usage was so much less than they had expected We are very happy with the results; the house is much more comfortable

Great company. Very professional and thorough. They take the time to explain everything and offer options to fit your budget. Wonderful experience from start to finish.

Bonnie Eustace

They were highly recommended. I found them to be very knowledgeable and so helpful, with practical ideas. Despite my not living within their service area, they were generous with their knowledge, describing the usual solutions to correct leaks in my basement, and what the result is likely to be by following path A, B or C, and why. I was discouraged. Talking with Evergreen helped me see that my basement problems are far from insurmountable and really, fairly common in 100-year old homes. There are proven solutions.

We just finished a large project air sealing and reinsulating our 1890s basement and attic. It 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.

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.

Linda Metzger

Evergreen did everything they said they would and more. I actually don't mind going into the basement now since they sealed it. The air quality in the house is noticeably better and it's warmer in the winter. We can even store clothing down there where before, whatever was in there would mildew. Even the spider population declined! I used to vacuum so many of them from the corners of the ceilings in the house. Not any more!

Loriel Van Dusen

I waited a year to write this review. Evergreen finished our job late last winter. Terrific results!!! we've gone from 12-day propane deliveries to 30+ day propane deliveries. The house is noticeably warmer. The Evergreen crew was/is professional, prompt, thorough, scientific, gracious and immaculate with respect to keeping our house clean. Money well spent.

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).
