Old caulking dries, cracks and pulls away, and window leaks are one of the most common calls from residents. We remove the failed sealant, prepare the joint and reseal it with a high-performance sealant.
On taller buildings we work from scaffolding or lifts and water-test the worst openings after sealing.

Every job is different, so your final price is set in a written estimate after a site visit, once ESR has seen the job and confirmed the full scope. Permit and plan-check fees are passed through at cost. Hidden conditions (dry rot, old wiring or Plumbing, hazardous materials) are priced separately. As California law requires, a down payment is never more than $1,000 or 10% of the contract, whichever is less.

Questions
Window & Joint Sealing FAQ
How long does new sealant last?
A good sealant on a properly prepared joint usually lasts 10 to 15 years. Sun-facing sides wear faster and are worth checking every few years.
