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.

Greetings one and all! I am writing to express my gratitude to all involved in my insulation project.  From start to finish, I appreciate the universal theme which was maintained by each and every one of you, to ensure that my home was insulated and protected from freezing pipes as if it was your home. Andrea, thanks for helping me navigate my way to the project. Nate, thanks for the thorough initial assessment and the time you took to explain this project to me, step by step. Brian, thanks for setting up my project - so happy

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.

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.

Really great experience from start to finish with Evergreen. They helped us prioritize what needed to be completed first, and has made a significant difference in our hearing costs already. Plus they were really friendly and considerate to work with!

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.

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

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.

Mary Carey

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.

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.

I highly recommend Evergreen! 1st, I had a home efficiency inspection (that was free) & Bryan P. was great! He took the time needed, asked & listened to what I thought were priorities, explained clearly what he thought were priorities & why, then gave me numerous options. No pressure whatsoever. Then I had my attic sealed & insulated as the 1st step & Bryan came along on day 1 to introduce everyone & make sure we were all on the same page. Bruce's team (inc. Kelsey & Roland) did the work - they were exceptional!!

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).

We had Evergreen come out to our tiny old (100+ year old) house to see what they would recommend for decreasing our carbon footprint, saving money, and increasing our comfort in the cold season. Richard and Bryan were great to work with, patiently answering our many questions and walking us through multiple options. We could only afford to tackle a few areas this year; we ended up replacing some windows and having them weatherize the entire house.

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 have always been impressed by the high level of service, quality of work, and excellent follow-through provided by Evergreen Home Performance in the three projects that they completed at the Wells Reserve at Laudholm over the past several years.

Evergreen came out 2 years ago to do an assessment and insulate our roof. This year we had them come back and do the basement as well. They are hands-down the best crew we've ever hired to work on our house. They are experts at what they do, and super meticulous in their work. After working in our house for a week with blown insulation, there was no trace they were ever here. We've seen a huge decrease in our energy bills while at the same time the house has become way more comfortable. Can't recommend them enough.
