Frequently Asked Questions
- How often should exterior caulking be replaced?
- Most exterior caulking should be inspected annually and replaced every 5–10 years depending on sun exposure and sealant quality. Failed caulking is one of the most common sources of water intrusion.
- What type of caulk is best for waterproofing?
- Polyurethane sealants are the most durable for exterior waterproofing. Silicone is best for areas needing flexibility. We match the sealant to the specific application for maximum longevity.
