Waterproofing Rental Properties in Garden City, ID
In Garden City, many rental properties sit close to the Boise River or in older developments where water intrusion is common. Whether you manage single-family rentals, duplexes, or apartment complexes, water damage is one of the most expensive and disruptive risks you face as a landlord.
In this article, we’ll share practical waterproofing tips that help Garden City landlords reduce water damage claims, protect tenants, and avoid costly restoration bills.
Why Garden City Rentals Are at Higher Risk
Water damage in rental properties happens for many reasons — not just floods:
- Boise River overflow or rising groundwater during spring runoff
- Tenant neglect (overflowed tubs, slow leak reporting, etc.)
- Old foundations, poor grading, or outdated sump systems
- Shared plumbing systems in multifamily units
Waterproofing Tips for Landlords
1. Inspect Crawlspaces and Basements Annually
Check for moisture stains, condensation, or foundation cracks. If a tenant reports a musty smell, don’t ignore it — mold may already be forming.
2. Seal Exterior Walls and Foundations
Apply waterproof coatings to foundation walls. Caulk exterior gaps and cracks to keep water out. Grade landscaping away from the structure to divert runoff.
3. Install or Upgrade Sump Pumps
Every basement or low-level unit in Garden City should have a sump pump with a battery backup — especially near the Boise River.
4. Educate Tenants About Water Issues
Provide simple instructions on what to do if they notice leaks, drips, or flooding. Encourage quick reporting to avoid hidden mold or structural issues.
5. Use Water Sensors and Smart Leak Detectors
Install moisture alarms under sinks, in utility closets, or basements. These can send alerts before a small leak becomes a major problem.
