Moisture & Mold Isn’t Just a Basement Problem – It’s a Whole-Home Concern

Did you know that a wet or damp basement doesn’t just stay in the basement? Excess moisture rises through your home. Frequently an old leaky home with a wet basement can have moisture condensation that results in that moisture showing up in the attic, with mold on the roof deck due to poor attic air sealing and attic ventilation. If you have signs of attic mold, the moisture very well could have come from a wet basement!

A damp basement also creates the perfect environment for mold and mildew to thrive, and once established, mold releases spores that can infiltrate your entire home, impacting indoor air quality and your family’s health. Additionally, moisture and mold can deteriorate building materials like wood, drywall, and insulation.

Here’s a picture we took from a Maine basement we inspected. The humidity levels were so high that a dead spider had white mold growing on it! This is surprisingly common for us to find, and a telltale sign that your basement needs help!

Increased humidity levels also creates the perfect environment for dust mites to thrive in your home – in your carpets, bedding, and furniture, where they feed on skin cells.

By controlling moisture at the source with proper basement waterproofing, you’re not just protecting your home from water damage – you’re also creating a healthier living environment upstairs by reducing dust mite populations and improving overall air quality. It’s one of the hidden health benefits of keeping your basement dry and your home breathing easier.

Why Mold Grows – and How to Prevent It

Mold thrives in environments where humidity levels are above 50%. And a moisture-ridden basement or crawlspace is exactly the kind of dark, damp place they need.

What causes excess basement humidity?

  • Humid Maine summers
  • Ponding water in your basement floor from rain
  • Plumbing leaks (common and often unnoticed in old Maine basements)

Left unchecked, this leads to:

  • Mold and mildew
  • Rot and rust
  • Poor indoor air quality
  • Damage to storage, furniture, and HVAC systems

Wet Maine basements and crawlspaces can introduce additional respiratory hazards and allergens that can exacerbate allergies and asthma. You don’t want to worry about what’s growing behind your walls or under your feet and whether the air in your home is safe for your family to breathe

That’s why Evergreen starts every basement consult by understanding the full moisture picture, so we can recommend the right steps in the right order.

Evergreen’s Comprehensive Approach to Mold Prevention

Evergreen doesn’t provide mold remediation or cleanup services. If your basement already has significant visible mold, we’ll refer you to a trusted professional for safe removal before we solve the causes of the excess moisture that led to your current issues.

Our team is focused on solving the root causes of home moisture and mold problems. Depending on the specifics of your home, we have integrated basement waterproofing solutions and crawlspace encapsulation services which can include:​

  • Interior French drain systems that redirect water out of your basement or crawlspace
  • Sump pump installation with battery backups that ensure continuous operation during power outages
  • Vapor barriers that seal out ground moisture while also controlling soil gases like radon
  • Dehumidifiers that help maintain optimal humidity levels​ (Every Maine basement needs a dehumidifier!)

Together, these upgrades create a basement or crawlspace where mold and mildew can’t take hold.

Protect Your Home – and Everyone Who Lives in It

Mold exposure can lead to respiratory issues, allergies, and other health concerns. But with Evergreen’s help, you can:

  • Lower your risk of mold growth
  • Improve the quality of the air your family breathes
  • Preserve the value of your home for the long haul

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!

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!

Joel A.

Very easy process, start to finish.  Friendly, professional, and really know their stuff.  They made some improvements to our condo and we were very happy with how it played out.  Would definitely recommend them.

Clayton Eames

Evergreen has insulated two homes that we've owned now and both times we experienced exceptional service and craftsmanship. Our rep, Justin, went above and beyond answering questions and the installation team was attentive to every detail, including pulling out old poorly installed insulation and redoing a bathroom fan that wasn't up to current code. They also left the place spotless every day! Our home is already so much warmer this fall and we are looking forward to using less oil this winter.

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

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 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.

Evergreen did a fantastic job insulating our 1930's home. The onsite team was professional, clean, and really just a joy to interact with throughout the process. A blower test at the end showed a significant decrease in air leakage. I highly recommend Evergreen.

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

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 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.

Paul D.

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!

John S.

South Portland

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.

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!

Martha Bracy

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!
