It is typically better to repair a rotted windowsill rather than replacing the entire window unit. Utilizing professional epoxy repair methods allows us to restore the structural integrity of your existing window and extend its lifespan without the significantly higher cost associated with a full replacement.

Our approach involves a systematic restoration process:

• Consolidation: We remove decayed material and use epoxy-based consolidants to penetrate and solidify the remaining sound wood fibers.
• Rebuilding: Voids are filled with high-quality, two-part epoxy wood fillers that provide a durable and sandable surface to match the original profile.
• Moisture Management: We ensure the sill maintains a forward slope of 5 to 15 degrees and install metal drip caps to deflect water and prevent future decay.

However, a full replacement may be necessary if the rot has extensively compromised the internal wall framing. If you notice water stains, mold growth, or soggy framing inside your walls, we recommend a professional evaluation to address these structural issues before proceeding.

Let us help you get your project started. Because every home is different, estimates are preliminary and subject to change after site inspection and a full scope review. Project outcomes and timelines may vary based on site conditions, permitting, material availability, and unforeseen issues. Please consult a licensed contractor for definitive advice and verify licensure with the Colorado Department of Regulatory Agencies (DORA).
