Exterior Window Renovation

Healthcare Trust of America

Contractor: Walsh Construction

Commercial Renovation Project: Coastal restored the exterior window systems of HTA’s five story office building. Our crew painted 23,000 linear feet of mullion window frames with a high quality metal paint, PPG PSX 805. In addition, contracted a window film company to install all new architecture film on the spandrel glass windows, using Avery Extreme 20 Silver, a high-grade exterior tint. To complete this renovation, our crew removed and replaced 48,000 linear feet of deteriorated window gaskets and installed a silicone wet seal, DowSil 795, guaranteed by the manufacturer to last up to 20 years of weather and wear.

Finish Caulking

San Diego International Airport

Contractor: California Sheet Metal

New Construction Project: Coastal helped weatherproof over 20,000 square feet of San Diego International Airport’s new expansion, the 130,000 square foot Federal Inspections building. After California Sheet Metal installed custom metal panels to the exterior of the new facility, Coastal installed finish caulking on the panel joints using DowSil 795 to create a weather barrier to protect the substrate underneath. Dow’s silicone products are top of the line in construction sealants, and can typically last up to 20 years after install.

Coastal most recently worked with California Sheet Metal on another high profile weatherproofing project, Makers Quarter’s Block D, a 60,000 square foot collaborative office building.

Window Wet Seal

Evening Creek Drive, San Diego

Property Manager: H.G. Fenton Company

Commercial Renovation Project: Coastal wet sealed 9,102 linear feet of windows of commercial office buildings on Evening Creek Drive using Dow Corning 795 to ensure up to a 20-year life of the window joints. Repaired damaged windows by removing and replacing deteriorated gaskets rather than replacing the entire window system thus saving the property manager time and money.

We previously worked with H.G. Fenton on a variety of window wet seal, perimeter and tilt-up joint projects at their properties across the county.

Site Work: Ivanhoe Avenue

Keller Williams office building, La Jolla

General Contractor: White Construction

Commercial Renovation Project: Coastal coordinated with painters to seal 15,000 linear feet of aluminum panels quickly and under budget in the well known Keller Williams office building in La Jolla. We contributed to the building’s full exterior make over by installing new silicone sealant at exterior aluminum panels using Sika 1A and Dow Corning 795.

Our reputation led to this project after previously working with White Construction on multiple sealing projects including replacing sidewalk joints at Islands at Carlsbad.
