Chris re-caulked all my exterior doors and windows in 2012. The work he did and the product he used has stood the test of time and outlived my windows and doors. I just replaced my windows and doors this spring (used 2 companies). I wish Chris and his team could have done all the caulking for the new installations. The window company installers have been back several times already to correct deficient caulking work. Bluesky never had to come back in 10 years. Bluesky does excellent work and they use superior products that last!
