Many Bellingham homes feature CertainTeed windows, known for their classic style and durability. However, even high-quality windows eventually wear down due to our harsh Pacific Northwest climate. Topside Roofing provides professional replacement services to keep your home warm and dry.

How long do CertainTeed windows last in Washington? In the Pacific Northwest, CertainTeed vinyl windows typically last between 20 to 30 years. Consequently, older units may develop seal failures or drafts due to constant exposure to Bellingham's heavy rainfall and seasonal temperature shifts.

Signs You Need Window Replacement

Specifically, local homeowners often notice moisture buildup between glass panes. This indicates a failed seal, which ruins your window's insulating properties. Additionally, look for these common warning signs:

• Difficulty Opening or Closing: Swollen frames or hardware corrosion from salt air.

• Drafts near the Sill: Air leaks that force your heater to work overtime during Whatcom winters.

• Visible Mold or Rot: Resultantly, moisture can damage your interior drywall or window trim.

• Increased Noise: Outdated seals no longer block the sound of I-5 traffic or local winds.
