JRS Engineering is Now “4EA Building Science”

JRS Engineering LLC has rebranded and is now 4EA Building Science.

We are still the same company and same great team that you know, but we now have a new name and a new look in the U.S.

Over the next few weeks, our existing clients and industry partners will see a transition in our work product from our former JRS brands to 4EA Building Science.

Why the change? As we look forward to expanding to new markets and services in the U.S., we felt it was time for a change to better position our brand with the fundamentals of what we do. More about our new brand and our refined approach can be found on our About Us page.

In addition to our established Seattle office, we have now also expanded into California – learn more about that here.
