Novelty Hill Advises Sound Glass in Sale to LLM Ventures

SEATTLE, WA – October 22, 2025: Novelty Hill Capital, a leading middle-market investment bank based in Seattle, Washington, is pleased to announce that its client Sound Glass has been acquired by LLM Ventures, a strategic buyer and owner of construction and construction-related services companies. For over four decades, Sound Glass has been a premier provider of window and door products and services in the Greater Puget Sound region, serving homeowners, contractors, and remodelers with a commitment to quality and community.

Novelty Hill Capital served as the exclusive financial advisor to Sound Glass on the transaction, honoring the legacy built by founder Warren Willoughby while positioning the company for its next phase of growth through additional opportunities for scale and expanded markets. LLM Ventures, focused on commercial, light commercial, and residential construction, is well positioned to build upon the strong foundation and market leadership Sound Glass has established since its founding in 1983 in Lakewood, Washington, with showrooms in Tacoma
and Bremerton.

Nick DeVaney, Managing Director at Novelty Hill Capital, emphasized the importance of honoring legacy in business transitions: “Sound Glass was and is the market leader with a 40+ year history. The natural progression of the company, employees, and opportunities for growth aligned well with Warren’s timing and desire. When a company and owner possess such a respected legacy and history, you naturally want to honor them in every facet of the deal allowable, which also means structuring a deal that allows that legacy to continue.”

The transaction furthers Novelty Hill Capital’s leadership in the industrial, construction, and services industries. For more information, please contact Nick DeVaney and Sean Ostrander of our industrials team.
