James Hardie Elevated
As a James Hardie Elite Preferred contractor, the highest level in the James Hardie installation program, we offer exceptional siding solutions. James Hardie excels at high elevations due to its low maintenance requirements, pre-finished ColorPlus technology, and resistance to wood-borne insects, including woodpeckers.


Pella Windows Peak Performance
We also offer windows designed for high-elevation performance. Our Pella Impervia fiberglass windows feature extremely stable frames with minimal expansion and contraction. They are maintenance-free and have an authentic “mountain” appearance, unlike vinyl options.
For a warm, genuine wood look, we offer Pella Lifestyle and Reserve lines with wood interiors (available unfinished, pre-finished, or pre-stained) and beautiful, maintenance-free aluminum clad exteriors. For the most durable cladding option, inquire about the Reserve line.
