Stop drafty windows in winter by sealing visible gaps short-term and planning a window replacement in Swampscott long-term.
Drafts usually mean failed seals, worn weatherstripping, or single pane glass that can’t keep up with North Shore winters. Short-term fixes help, but replacement delivers permanent comfort and lower bills.
What Swampscott Homeowners Need to Know:
| Fix | Pros | Cons | Best For | Cost Range |
| Weatherstripping | Cheap, fast | Temporary, doesn’t fix glass | Renters, mild drafts | Low |
| Caulking | Easy DIY | Cracks over time | Visible gaps in trim | Low |
| Window film | Insulates extra layer | Looks cluttered | Single-season fix | Low |
| Triple pane replacement | Permanent fix, $500+/year savings | Higher upfront | Long-term homeowners | Higher upfront, long payback |
- Triple pane savings: Upgrading from single to triple pane windows can save over $500 per year on energy bills.
