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

Led by Brian Robinson, the Evergreen Home Performance team just completed an insulation refit at my home. It was truly a great experience from start to finish, a period of time that was a fraction of the time that I originally anticipated due to the team's unbelievable work habits and professional knowledge of their tasks. As impressive were the communication skills and friendliness of each and every member of the team.

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.

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.

Update 12/2018: Evergreen has completed Phase II of my house (insulating and installing air/moisture barrier on exterior walls, replacing old windows) and now that heating season is upon us, the difference is astonishing. The house is tight as a drum and so easy to keep warm. Worth every penny. Thank you all! Working with Evergreen was a positive experience from start (no charge energy audit) to finish (a MUCH more comfortable home). Brian Robinson spent a lot of time with me on the audit, explaining clearly what he was finding in my ca.

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.

Bonnie Eustace

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!

We couldn't be more pleased with the easy, professional, high-value service from Evergreen. Having purchased an older home that had been in our family for generations, we needed multiple upgrades, including insulation throughout. Evergreen insulated our attic with blown-in cellulose, built a new, super-insulated attic hatch, sealed off the old one (which was just a piece of plywood in a closet ceiling), and also talked us through our best options to upgrade our heating system given the plans we have to add onto the house.

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!

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 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.

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.

RC Lations II

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.

My experience with Evergreen was excellent. From their thorough and thoughtful initial consultation to their detailed post-work visit, the team was professional, knowledgeable, and responsive. Their workmanship was top notch. Our home is now much warmer and more efficient. I highly recommend their services!

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!
