This article provides a detailed breakdown of window resealing costs, factors affecting pricing, and practical tips to help you budget effectively.
Quick Reference: Average Window Resealing Cost Table

What Does Window Resealing Involve?
Window resealing refers to the process of fixing or replacing the sealant material around the perimeter of a window. This includes replacing dried or cracked caulk, repairing broken seals in insulated glass units, and addressing leaks or drafts. Professionals typically use weatherproof caulk or silicone-based sealants for optimal results.
The Key Steps in Resealing a Window:
- Inspection and identification of damaged or deteriorated seals
- Removal of the old caulking or sealant
- Surface cleaning and preparation
- Application of new high-quality sealant
- Finishing, cleaning, and curing
Resealing can be a straightforward DIY task for a handy homeowner, but challenging window placements or severe damage often require professional help.

- Type of Window: Double-hung, casement, bay, and bow windows may require different resealing techniques and materials.
- Window Size: Larger or unusually shaped windows demand extra labor and more materials.

Cost Breakdown: Labor, Materials, And Additional Services
The bulk of resealing expense generally comes from labor, especially for professionals. Here’s a more granular look at what contributes to your final bill.
| Cost Item | Typical Price Range | Description/Examples |
|---|---|---|
| Labor (per window) | $40 – $120 | Includes inspection, removal, reseal, and cleanup |
| Sealant Materials | $5 – $18 | Weatherproof caulk, silicone, tools |
| Repair for Wood Rot/Frame Damage | $30 – $150 | Patching, filler, and sanding |

Professional companies often provide “bundled” pricing, so a clear, itemized estimate is essential before work begins.
DIY vs. Professional Window Resealing: Cost Comparison And Considerations
Tackling window resealing as a DIY project can save substantial money, but introduces some risk if not performed correctly. A cost comparison is key to making an informed decision.
| Aspect | DIY Approach | Professional Service |
|---|---|---|
| Upfront Cost | $10–$50 per window | $70–$150 per window |
| Skill/Experience Needed | Moderate to high | Professional expertise, guaranteed quality |
| Time Required | Varies (30–90 mins per window) | Usually faster, less hassle |
| Warranty | None (unless self-insured) | Often included for 1+ years |
| Potential Mistakes | Possible leaks, improper finish | Less risk; professionals stand behind their work |
Cost By Window Type: What Should Homeowners Expect?
Not all windows are alike, and costs to reseal windows can vary widely based on type. Specialized shapes or features often increase the complexity.
| Window Type | Typical Professional Cost Per Window | Comments |
|---|---|---|
| Single/Double-Hung | $70 – $120 | Most common, relatively easy access |
| Casement | $80 – $130 | Additional hinges, better sealing needed |
| Bay/Bow | $150 – $300 | More glass area and joints |
| Picture Window | $95 – $190 | Large, fixed panes; more sealant required |
| Sliding Window | $70 – $140 | Track cleaning may add labor |
| Skylight | $120 – $400 | Hard access, higher risk of leaks |
How Materials Affect The Cost To Reseal A Window
Sealant materials form a key part of resealing expenses. Choosing the right product affects both performance and price.
- Silicone Caulk (Standard): $6–$12 per tube. Long-lasting, waterproof, suitable for most window types.
- Polyurethane Caulk: $7–$16 per tube. Strong adhesion and flexibility; good for extreme temperature zones.
- Specialty/Color-Matched Caulk: $8–$18 per tube. Blends with window trim for a professional look.
- Window Glazing Compound: $6–$14 per tub. For older, single-pane window restoration.
Professionals may recommend higher-end sealants in areas with temperature swings, UV exposure, or historic properties.
