Local risk factors in Johnston
Because of these factors, Johnston homeowners most often need roofing, mold remediation and hvac.
Severe storms lift shingles, drive rain under flashing and push on garage doors. Wind-rated materials and solid nailing patterns pay off here.
High humidity feeds mold in bathrooms, attics and crawl spaces and makes air conditioners work harder to dry the air.
Heavy rain and flooding soak floors, drywall and foundations. Standard homeowners policies exclude flood, so check your coverage.
