Exterior siding in Northern Idaho ages under significant stress: heavy snowfall, freeze-thaw cycles, spring moisture, and intense summer UV. Most homes in Benewah and Shoshone counties with original wood siding from the 1960s through 1980s are overdue for evaluation.
Signs Your Siding Needs Attention
Paint bubbling or peeling in large sections. Paint failure usually indicates moisture infiltration from behind the siding, not just surface weathering. Repainting without addressing the moisture source is money wasted.
Soft spots when you press on the siding. This is rot. Press at several points along the lower courses, around window and door trim, and at any areas where two surfaces meet. Soft spots mean the siding has lost structural integrity.
Cracked or splitting boards. Longitudinal cracks that allow water infiltration accelerate deterioration in Northern Idaho's freeze-thaw climate.
Visible gaps at seams or caulk failures at trim. Gaps are water entry points that grow larger every freeze-thaw cycle.
Insect damage. Carpenter ants and woodpeckers are drawn to siding that has begun to rot. Their presence indicates deterioration is already underway.
When to Repair vs. Replace
Spot repairs work when damage is isolated to specific boards and the surrounding siding is in good condition.
Full replacement is appropriate when more than 30 percent of the siding surface shows deterioration, when the moisture source is systemic (failed flashing, inadequate housewrap), or when the existing profile is no longer available for matching.
Material Choice for Northern Idaho
For most Benewah and Shoshone County homes replacing aging wood siding, James Hardie fiber cement is the most durable long-term choice. LP SmartSide is a strong alternative where natural wood appearance is important.

What the Project Involves
Full siding replacement includes removal of existing siding, inspection and repair of sheathing and housewrap, installation of new moisture-resistive barrier where needed, new siding per manufacturer specifications, new exterior trim, and caulking.
