Westbrook industrial property sold for $13M in off-market deal 09/10/2025

We’re excited to share that our brokers, TC Haffenreffer and Sylas Hatch, successfully represented the buyer in the off-market sale of a prime industrial property at 22–48 Spiller Drive in Westbrook, which closed at $13 million. Steve Baumann of Compass Commercial Brokers and Josh Soley from CORE represented the seller, Spiller Drive LLC.

The 134,000 SF property, anchored by leading glass and metal fabricator SIGCO, checked all the boxes for buyer NRTI—a joint venture between North River Company and Two Island Real Estate.

This deal reflects continued strength in Maine’s industrial market and demonstrates The Dunham Group’s ability to deliver strategic, high-value solutions—even in off-market scenarios.

Congrats to all involved!
