Why Silicone & Sealant Repairs Are Important
Over time, the silicone and sealants around glass, windows, doors, and curtain wall systems can deteriorate due to UV exposure, temperature changes, or building movement. Damaged or missing sealant can allow water intrusion, cause air leaks, and reduce energy efficiency — leading to costly repairs if ignored.

FAQs
How long does sealant last before needing replacement?
Most exterior silicone sealants last 10–20 years, but harsh weather can shorten their lifespan.
Can you repair only the leaking section?
Yes — we can do targeted repairs, but we always recommend inspecting the entire perimeter to avoid future leaks.
What type of silicone do you use?
We use premium, construction-grade silicone that remains flexible and weatherproof in extreme temperatures.
Do you offer warranty on sealant work?
Yes — all our sealant repairs are backed by a workmanship warranty.
