7 Signs It's Time to Replace Your Windows (Not Just Repair Them)

We get a lot of calls that start the same way: "I don't know if this window needs fixing or if I just need to replace the whole thing." Fair question — and honestly, the answer isn't always obvious just by looking at it. Here are the signs we actually look for when we're deciding whether a repair will hold up, or whether replacement is the smarter call.

1. You Can Feel a Draft, Even With It Fully Closed

If you can hold your hand near the edge of a closed window and feel air moving, the seal between the sash and frame has failed. A little weatherstripping can sometimes help, but if the draft is coming from the frame itself shifting or warping, no amount of caulking fixes that permanently.

2. The Glass Is Foggy Between the Panes

This one's specific: fogging on the glass wipes away. Fogging inside the double-pane glass — between the two layers — does not. That's a failed seal on the insulated glass unit, and it means the argon or insulating gas is gone. It's not repairable in the sense people hope; it needs a new sealed unit, minimum.

3. It's Hard to Open, Close, or Lock

Windows that stick, won't stay open, or won't lock properly are often telling you the frame has swollen, warped, or shifted — usually from moisture getting into the wood or the frame settling with the house. A little lubrication can help a sticky window, but if it's a structural warp, that's a replacement conversation.

4. Your Energy Bills Have Crept Up, and You Can't Explain Why

Old single-pane or early-generation double-pane windows lose heat fast, especially in Western Washington's wet, cool winters. If you've ruled out your furnace, insulation, and ductwork and your bills are still climbing, your windows are a very common hidden culprit.

5. You See Wood Rot, Soft Spots, or Peeling Paint Around the Frame

This is a big one. Moisture that's been getting into the frame for a while will soften the wood, cause paint to bubble or peel, and eventually rot the frame from the inside. Glass repair does nothing here — once the frame itself is compromised, replacement is the only real fix.

6. Outside Noise Feels Louder Than It Used To

Aging seals and thinning glass let more sound through over time. If a busy street or a neighbor's yard suddenly feels louder than it did a few years ago, it's often not your imagination — it's your windows losing their sound-dampening properties as the seals degrade.

7. The Window Is Original to an Older Home

If your house is 20-30+ years old and still has its original windows, age alone is a meaningful factor. Most window seals and hardware are built to perform well for roughly 15-20 years. Past that point, even windows that "look fine" are often quietly underperforming on insulation and efficiency.

What If You're Still Not Sure?

Honestly, that's normal — some of these signs overlap with simple maintenance issues, and it's not always obvious from the outside which one you're dealing with. That's what a free estimate is for. We'll take a look, tell you honestly whether it's a repair or a replacement situation, and never push you toward the more expensive option if the cheaper one will actually hold up.
