At Coastal Windows & Exteriors, We Believe in Going Green—for a Lifetime!

At Coastal Windows & Exteriors, we believe in not only going green, but going green for a lifetime.
We don’t just talk about sustainability—we integrate it into every area of our business.

That’s why we help our customers protect the Earth in three meaningful and lasting ways:


1. Material Selection: Durable and Eco-Friendly

First, we offer environmentally-friendly products that come with a lifetime warranty.
You’ll never need to paint, stain, or strip them—saving time and avoiding harmful chemical releases.
As a result, fewer volatile compounds enter the air, helping improve both indoor and outdoor air quality.


2. Energy Efficiency: Saving Energy and Money

Next, we focus on designing complete systems, not just selling products.
Our energy-efficient windows and doors reduce heat loss, which lowers your utility bills year-round.
More importantly, this helps cut your home’s carbon footprint.
In other words, your home becomes more comfortable and more sustainable.


3. Indoor Environmental Quality: Healthier Living

Finally, our eco-conscious products don’t just protect your home—they protect your family.
We install materials that seal out moisture, reducing the risk of mold and mildew.
This means cleaner indoor air, fewer allergens, and a home environment that supports your health.
In short, going green with us means breathing easier—literally.

Introducing The Green Alliance (GA)

In keeping with our mission, we’re proud to introduce our customers to The Green Alliance (GA), based in Portsmouth, NH.

The GA’s purpose is to connect green-minded consumers with businesses that share the same sustainable values.
Specifically, the GA performs sustainability certifications for each business partner.
These are then made visible to the public on the GA website, along with a “Green Story” that shares the journey toward eco-consciousness.


Why Join the GA Community?

Individuals join the GA not only for generous member discounts—but to become part of a like-minded green community.
This community regularly hosts events where you can meet local business owners and fellow eco-enthusiasts.

For example, members enjoy access to:

  • A Summer Party Cruise with Isles of Shoals Steamship & NHPTV

  • A Spring Music Bash at Red Hook Brewery

  • And many more exciting events

Best of all, these events are completely free for GA members!


Summer Membership Bonus: Free Gundalow Tickets!

Now through October 1st, all new Sustaining Members of the GA receive two free tickets for a sail with the Gundalow Company out of Portsmouth.
Each ticket is valued up to $40, so your membership could pay for itself immediately.


Why Lifetime Sustaining Membership Matters

While there are many ways to support the GA, the Lifetime Sustaining Membership offers the greatest impact.
Not only does it show lasting support for local sustainable businesses,
but it also reflects a long-term commitment to environmentally responsible living.
