Discover how to care for Andersen windows in coastal San Diego. Protect your investment with essential maintenance tips against salt spray and UV damage.
Andersen windows are known for timeless design, energy efficiency, and lasting durability. But in coastal communities like Del Mar and La Jolla, even top-tier windows need the right care to stand up to the elements—and to avoid mistakes that can quietly cost you.
Whether you’ve recently installed Andersen windows or inherited them in a luxury home, this guide will show you how to maintain them safely—and why hiring a professional may be the smartest move you can make.
Andersen’s reputation is built on:
Premium materials like wood, Fibrex® composite, and aluminum-clad exteriors
Extensive customization for high-end and historic homes
ENERGY STAR-rated performance
Modern options like tilt-wash windows for easier cleaning
In neighborhoods like Del Mar, Rancho Santa Fe, and Solana Beach, Andersen windows are a top choice for homeowners who value beautiful design with lasting function—especially in homes built around views.
Andersen windows are built to last, but San Diego’s coastal climate is harsh on glass, seals, and finishes—especially when maintenance is skipped or done incorrectly.
Here’s what our team sees most often in Del Mar homes:
Salt spray leaves a fine film that slowly etches glass
High humidity and fog corrode frames and hardware—especially wood and metal finishes
Sprinklers and hose water create hard mineral spots that no standard cleaner can remove
UV rays break down finishes and sealants, especially on south- and west-facing windows
Regular cleaning isn’t just about the view—it’s about preserving your warranty, resale value, and window performance.
Following Andersen’s official care guidelines, here’s how we help homeowners protect their investment:
This removes winter salt and summer dust. For oceanfront homes or homes with irrigation near windows, quarterly cleaning is ideal.
Mix 2–3 gallons of water with a light squeeze of mild dish soap. Avoid anything with ammonia, alcohol, or vinegar—especially on Fibrex® frames or Low-E glass.
Soft microfiber cloths
14"–18" brass or stainless-steel squeegee
Non-abrasive sponges
Large paintbrush or handheld vacuum to clear tracks and sills
Trying to “DIY” with Windex, paper towels, or hard tap water? You could be scratching coatings, voiding warranties, and wasting time.
Lay down a towel to catch drips
Gently vacuum or brush away dirt and spiderwebs
Wipe down the sill and frame with a damp cloth
Clean the glass using your solution and squeegee—top to bottom, wiping blade between passes
Tip for two-story homes: Andersen’s tilt-wash windows let you clean the outside glass from inside, so you or your spouse never have to risk a ladder again.
Remove screens and gently scrub with soap and a soft brush
Clean the frame with a microfiber cloth
Avoid direct sunlight—cleaning in shade prevents streaks
Wash glass top-down with a T-bar scrubber and squeegee
Dry frames thoroughly to prevent moisture damage
One of the most common mistakes we see? Hosing down windows with hard San Diego water. Even soft water will leave etching, void warranties, and degrade performance over time.
Pressure washing windows (forces water into seals)
Using razor blades or steel wool (scratches protective coatings)
Skipping seasonal cleans (buildup gets harder to remove and more expensive to fix)
Using newspaper (can stain wood frames)
Waiting until the view is cloudy before taking action
Andersen windows are built to last—but only when cared for properly.
