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

I had gotten estimates from several other companies, but Evergreen was in another league entirely with their professionalism. If you want the job done correctly, I couldn't recommend this company enough.

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 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 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.

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

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 completed the work at my home thoroughly and professionally. An inspector from Efficiency Maine came to inspect afterwards and described it as "state of the art" and "outstanding". The crew was very pleasant and considerate during the project. Their cleanup each day was perfect. Communications with the office were easy and reliable. I am very satisfied.

I made the mistake of NOT hiring this company last year when I bought and renovated my home. I have brought them in now and what a difference. This group knows what they are doing. They take a complete look at everything and believe they can make your home more energy efficient. They are very professional in the way they approach problems and solutions. And they find ways to save me money. Don't bother with anyone else. Bring Evergreen in before you do anything. Let them assess your issues and give you the right solutions.

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

We absolutely loved our experience with Evergreen. The team was incredibly kind, professional and great to work with. We're very impressed with the quality of work of the Evergreen team and how easy they made everything! Our house had barely any insulation ahead of this project and the results are amazing. Insulating the attic, walls and basement with Evergreen allowed us to tear a 50-year-old furnace, ductwork and oil tank out of the basement and now heat the home with new heat pumps. Evergreen also added 100 sq ft of clean, new storage space to the attic!

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!

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.

Bob & Sue

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.

Working with Brian and with Nate and the rest of the crew was a pleasure. They made everything very easy and understandable. This was a major renovation and they were always at the ready with a lot of information. We had an extensive renovation on the basement which was a dirt basement and it came out beautifully. We can already tell from all of the insulation work what a difference it's made in sound and temperature. Brian worked with me on the rebates that are available when you do this kind of work. I would highly recommend this company to…
