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.

Evergreen came back this year to finish insulating our house. We have been remodeling and renovating an 1850s cape for several years. Their employees are very professional and pleasant to deal with. Over several years Brian Robinson has been able to schedule us in for several small areas that needed addressing and finally turning a room we used to close off in the winter into a comfortable usable space. We primarily heat with wood and since Evergreens great work our furnace has only come on ONCE this winter. Fantastic. Really satisfied customer in Thomaston.

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!

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…

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.

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!

Thanks Evergreen Home Performance for helping to make our home more efficient. Many thanks as well to Bryan for the initial walk through and recommendations to make our home more efficient and to Dave, Roland, and Jacob for a job that was done professionally and courteous.  We were amazed at the level of efficiency and everyday they made sure to protect our floors, carpets, and furniture. We had daily discussions with Dave about progress and what was being done and where they were at in the project.

Carol Fink

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

I was extremely pleased with the professionalism and quality of service that I received from the Evergreen team. I met Richard to discuss options for insulation. I knew immediately that I wanted to do business with them because he did not try to over-sell extra services that I did not need. Dave was the project manager. He was not only kind, but very respectful of my home. I would highly recommend this company.

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.

Odette Brown

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.

Joel Wentz

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.

The team members were very professional, worked very hard, paid very close attention to detail and cleaned up meticulously every day. I really appreciated the care they took knowing the smallest details were going to make a big difference to our heating bills. Thank you!

We had Evergreen Home Performance of Rockland come in to make our home more energy efficient, and what a TOP notch crew. Brian and his crew did an amazing job from start to finish. Very knowledgeable and professional. We would Definitely highly recommend this crew to anyone who is looking for energy efficiency in their home with a company that truly is an expert and knows how to do a quality job and truly cares about their customer.

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.
