Celeste·Windows
Light, comfort, thermal precision.
Windows are the interface between your home and the outside world. They shape how light enters, how heat moves, and how your home feels. Celeste specifies and installs window systems that perform as well as they look.
Scope of Work
What we do.
Full Window Replacement
Complete removal of existing windows and installation of new units — including frame, trim, and weatherproofing.
Insert Replacement
New window units installed within existing frames where frame condition permits — less invasive, faster installation.
Sliding Door Replacement
Replacement of sliding glass doors with modern, thermally broken systems — often the largest source of heat gain in a home.
Condition Assessment
Standalone evaluation of your existing windows — thermal performance, seal failure, frame condition, and hardware.
Product Philosophy
We specify what we believe in.
Celeste evaluates window systems on thermal performance, durability, and design integrity. In Southern California, the primary concern is solar heat gain — the wrong window can significantly increase cooling loads. We specify products with verified performance data, not marketing claims.
Low-E Glass
Required on all Celeste window specifications — reduces solar heat gain without sacrificing visible light.
Thermally Broken Frames
Aluminum frames with thermal breaks prevent conductive heat transfer through the frame itself.
NFRC Ratings
We specify products with verified NFRC ratings — U-factor, SHGC, and VT — not manufacturer estimates.
ENERGY STAR Certification
All Celeste window specifications meet or exceed ENERGY STAR requirements for the Southern California climate zone.
Process
How a Celeste window project works.
01
Assessment
We evaluate your existing windows — documenting seal failures, frame condition, thermal performance, and hardware.
02
Scope & Specification
We develop a replacement scope and specify the appropriate window system for each opening — considering orientation, exposure, and architectural context.
03
Measurement
Precise field measurement of every opening — the foundation of a clean, weathertight installation.
04
Installation
Careful removal of existing units, proper flashing and weatherproofing, and precise installation of new windows.
05
Completion
Interior and exterior trim, hardware adjustment, and a final walkthrough to verify operation and weathertightness.
Southern California considerations.
Solar Heat Gain
South and west-facing windows in Southern California can dramatically increase cooling loads. Proper SHGC specification is critical.
Coastal Corrosion
Within a mile of the coast, hardware and frame materials must be specified for salt air resistance.
Seismic Performance
Window installations in California must accommodate building movement. Proper shimming and flashing details matter.
Title 24 Compliance
California's energy code has specific requirements for replacement windows. Celeste ensures every installation is compliant.
