Northwest Exteriors offers home improvement products to residential customers in Sonoma, Marin, Napa, Lake, Mendocino and Solano Counties. The company provides energy-efficient windows, doors and siding.

When a customer first contacts Northwest Exteriors about a home improvement project, a company specialist begins by setting up a free in-home evaluation. A representative then weighs the customer's personal, environmental and financial goals to propose a custom solution from a choice of different manufacturers. “We’ll analyze our customers’ wants and needs to determine the best possible products that will benefit them the most,” says General Manager Rick Pellhum.

Northwest Exteriors’ representatives are familiar with government programs and financing solutions, and they ensure homeowners have everything they need to maximize available incentives and affordably install their projects. The company is also a Master Distributor of Anlin Window Systems and installs CraneBoard and James Hardie siding products.

(Reviews: Scroll down to read them.)

Our surveys of only verified real customers produce the country’s most accurate ratings of local companies. Northwest Exteriors scored Highest in Quality and Helpful Expertise and passed the credential-based checks to earn Diamond Certified.

A Star Equivalent Score is calculated for each verified customer rating by weighting the 1–10 Quality score, the YES/NO Loyalty (intent to return) score and the YES/NO Helpful Expertise score. If Helpful Expertise wasn’t surveyed or didn’t apply, it’s simply not shown.
