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.

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.

I used to spend winters in the bathtub because my house was so cold. This was my first winter roaming around my whole house comfortably. This even led me to decorate a little. My heating oil usage has been reduced by over a quarter: I rarely have to boost the thermostat because the temp stays at a constant. The Efficiency Maine rebates, together with the energy savings, make it affordable for me to pay for the loan I took out to finance the project. I do not worry about my pipes freezing.

We had Evergreen redo the insulation in our roof. The team handling our project did a great job. They left the house spotless. We've already noticed the difference in how much better our house is retaining heat. I would definitely recommend and will use them for future projects.

Evergreen is a terrific company to deal with. Polite and efficient crews, meeting deadlines and major reduction in our heat bills. They corrected a lot of issues we suffered from doing work with a shoddy building contractor. We would recommend them to anyone.

Very Satisfied with the work performed by Evergreen. Professional employees, high quality work done in a timely manner. My sales rep was Justin, and he was phenomenal During the initial walk around my house, he gave me great ideas for how to improve the efficiency of our home. We will consult with Evergreen for our future home projects.

Evergreen was so helpful in securing us Efficiency Maine funding for a big attic insulation project early this winter. They did all of the paperwork, and totally guided us through a vermiculite removal process that included a payment from a trust for the procedure. I could instantly feel the second floor being so much warmer than before. The boiler does not kick on nearly as frequently since they completed the job. It was worth every penny! Brian Robinson was so thorough throughout the whole process including a full walk through after the job had been completed.

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.

The Evergreen crew from initial inception to installation were professional, on time, and left our place spotless. The end result was exceptional.

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!

From beginning to end – that is from the moment Justin McEdward stepped into our home to assess our energy conservation needs until the crew left – the Evergreen Home Performance process went absolutely smoothly. Justin made a thorough inspection and took pictures with an infrared camera. His proposal described the scope of work in detail, and he explained what we could expect the proposed work to accomplish. Our proposal was forthcoming within a couple of days, and Justin was available to discuss it and answer questions.

I am very pleased with my experience with Evergreen Home Performance. I met several times with Richard Burbank and he was very detailed in his explanations to all of my questions. He provided me with several options for improving the insulation to our home. The team of installers were very professional and respectful of our home. They did a great job of cleaning up every day after the days work and they were also very responsive to all my questions as well as we collaborated to get our home better insulated. It was a pleasure to work with Richard and…

Several years ago Brian Robinson evaluated the crawl space at my summer home on Islesboro where I knew moisture was becoming a problem. I had done quite a bit of work in the space many years prior with mixed results. When Brian offered some suggestions, they were ideas that incorporated work previously done, and would be a relatively low cost effort to improve the situation. He offered this advice over several phone conversations of some length, informally, and at no charge.

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.

The Evergreen Team did a fabulous job, well exceeding our expectations, In just over a week they transformed our very drafty, noisy 213 year old house into a snug, draft-free, quiet haven with warm floors! The team was prompt, did everything they said they'd do and more. We are thrilled!

From start to finish, our experience was incredible. Justin was extremely helpful. The crew was fast, friendly, and efficient. And most importantly, our home is WAY warmer and our heating is less costly. I'd highly recommend evergreen to anyone looking to upgrade their home!
