How to Weatherproof & Insulate Your Home Before Winter in Southern California

In Los Angeles, “winter” rarely conjures snow or ice. Yet discerning homeowners on the Westside and in the Pacific Palisades know that cooler months bring their own challenges - seasonal rains, coastal winds, and sudden temperature drops in the evenings. At Gregory Greenwood Construction, we approach weatherproofing not as a checklist of repairs, but as an opportunity to refine your residence’s performance with the same care and attention given to its design.

The Subtle Realities of a Southern California Winter

Our climate rewards attention to detail. While mild compared to the East Coast, Los Angeles homes, especially along the Westside and Pacific Palisades, face unique challenges:

  • Salt-laden coastal air that accelerates corrosion and finish wear.
  • Seasonal rains that test drainage, flashing, and waterproof membranes.
  • Cooler nights that expose thermal weaknesses in glazing or insulation.

These are not inconveniences to patch but long-term considerations for maintaining a home’s serenity, energy performance, and architectural integrity.


Weatherproofing as an Art Form

True weatherproofing should never be visible, it should simply work. Our approach is both technical and aesthetic:

  • Fenestration refinement: We enhance glazing assemblies and weatherstripping to preserve transparency while sealing out drafts.
  • Roofing and flashing upgrades: Elegant metal and concealed drainage systems protect structure and design.
  • Drainage integration: Subsurface systems maintain landscaping aesthetics while safeguarding foundations.

Every element is engineered to blend seamlessly with your home’s design, protecting without intrusion.


Insulation Beyond Utility

Insulation, when done properly, elevates living. For us, it serves three purposes:

  • Comfort: Maintaining stable interior climates that enhance daily life.
  • Acoustic serenity: Shielding interiors from ambient city and coastal sounds.
  • Longevity: Protecting finishes, millwork, and art collections from subtle fluctuations in temperature and humidity.

We recommend reassessing insulation and weatherproofing every 3–5 years to maintain optimal performance and the quiet refinement your home deserves.

Our Perspective

For our team, weatherproofing is not maintenance, it is mastery. It’s about foresight, discretion, and detail. These invisible luxuries ensure your estate remains as enduring and elegant as the day it was completed.
