Nautic sells CWS to Pella

Nautic Partners has sold Custom Window Systems Inc to Pella Corporation. No financial terms were disclosed. Florida-based CWS is a maker of high-quality windows and doors.


PROVIDENCE, R.I.–(BUSINESS WIRE)–Nautic Partners, LLC (“Nautic”) announced today that it has sold portfolio company Custom Window Systems, Inc. and related affiliates (“Custom” or “CWS”) to Pella Corporation (“Pella”).

Custom designs, manufactures, and markets custom-configured, impact-resistant and non-impact resistant windows, doors, and porch enclosures serving both single-family and multi-family housing customers in Florida and the Southeastern U.S.

Headquartered in Ocala, FL, the company is a leading Florida manufacturer of vinyl residential windows and doors, with most of its revenue derived from impact-resistant engineered products that help to withstand wind and debris from hurricanes. Custom sells product primarily via the dealer channel, requiring greater sales and installation expertise due to local regulations and the technical nature of the impact-resistant product.

Chris Pierce, Managing Director of Nautic, said, “We thank John Manzi, Roger Sim, and the entire team for their accomplishments. Thanks to them, the company is well positioned for continued growth, with high quality products, a streamlined and efficient production facility, and plenty of capacity. It has been a pleasure partnering with them to achieve the goals that we had.”

John Manzi, CEO of Custom added, “We greatly enjoyed working with the Nautic team. They have been a stellar partner throughout Custom’s evolution over the past several years. We look forward to the next chapter for Custom under Pella ownership.”

Rod Miller, Custom VP of Sales and Marketing added, “We are extremely pleased to be a part of the Pella family. It is both a strategic and cultural fit that will afford us the opportunity to serve more customers by further expanding our capabilities in Florida and other key coastal regions. Pella has an outstanding reputation, and we’re pleased to be part of a strong organization with a rich history in the window and door industry and a strong commitment to drive accelerated growth.”

BlackArch Partners and KeyBanc Capital Markets served as advisors to Custom and Nautic.
