Still Family-Owned.
Still Here.
Wolf Exteriors & Remodeling was founded in 1975 by Don Wolf as a siding operation in the Watertown area. Jim Noltner took ownership in 1997, expanded the company into roofing, windows, gutters, doors, decks, and interior remodeling, and relocated to Oconomowoc in 2012 — where Wolf has been rooted ever since.
Nearly 50 years later, the business is still independently owned, still locally operated, and still built on the same foundation it started with: quality work and a reputation worth protecting.
Why Choose Wolf?
Nearly 50 Years of Experience
What we’ve learned over five decades of Wisconsin exteriors can’t be replicated by a company that showed up last year. That experience shows up in every assessment, every installation, and every problem we catch before it becomes yours.
Quality Materials, Certified Installation
We hold certified installer status with the manufacturers we carry, including James Hardie, LP Smart Siding, Owens Corning, GAF, Andersen, Marvin, and more. The right products, installed the right way, backed by people who stand behind their work.
Local and Accountable
When you call Wolf, you’re talking to the same people who will show up, do the work, and stand behind it. No 1-800 number, no runaround. We live and work in this community, and our reputation here is everything.
One Contractor, Full Scope
Roofing, siding, windows, gutters, doors, decks, interior remodeling and additions, storm damage repair. You don’t need five contractors. You need one you can trust with all of it.
