What customers are saying about us

These verified reviews from our long history of local service show why Fenix remains Montana's premier choice for exterior renovations.

"Jake did a wonderful job of installing our new siding. He's very particular and detailed in his work, which we really appreciated."

Bev Butler

"The Fenix crew was prompt and professional. Our windows were ready for installation ahead of schedule. The day of our installation was smooth and faster than expected. Everything looked perfect, and they cleaned up after themselves. We couldn't be happier"

Jill Pendleton

"Jake and his crew were fantastic. The end product of our new windows exceeded our expectations, and the crew left things better than when they arrived. They were friendly and courteous, answering every question we had. Will definitely use them again for our siding project."
