About Us Raising the Standard in Insulation & Coatings
509 Spray Foam started the way a lot of great trades do — out of frustration. As builders, we couldn’t find anyone to install spray foam properly. Every job felt rushed, uneven, or half-done. So we stopped hiring it out and started doing it ourselves.
We're Builders, Not Salespeople
As contractors first, we know what it’s like to chase subs, deal with callbacks, and settle for “good enough.” That’s never been our style. We launched 509 Spray Foam to raise the bar — with insulation that seals tight, coatings that last, and a team that actually cares how the job turns out.
We treat every job like it’s our own—because we know what it’s like to be on the other side of that sub list.

Frequently Asked Questions
How long does spray foam insulation last?
When it’s done right and stays dry, closed-cell spray foam can last for the lifetime of your building — no sagging, no settling.
Will it help keep my crawl space or basement dry?
Yes! Closed-cell foam is a moisture and vapor barrier, so it helps block out water and keep mold at bay.
What’s the difference between open-cell and closed-cell foam?
Open-cell is softer and cheaper, but doesn’t seal or strengthen as well. We use closed-cell because it seals better, adds structural support, and lasts longer.
Can it help with noise too?
Definitely — spray foam can help reduce sound transfer between rooms or from outside.
Is spray foam really worth the investment?
For most projects, absolutely. It’s more expensive up front, but it’s one of the few upgrades that pays for itself over time with energy savings and lower maintenance.
How soon can I get back in after install?
Most jobs are good to go within a day or so. We’ll talk you through any safety or ventilation needs before we start.
