Not Every Window Problem Needs a Full Replacement

That cloudy glass between your panes? It's usually a failed seal—not a failed window. The crank that won't turn? Often just worn hardware. The draft coming through? Could be weatherstripping, not the window itself.

After 55+ years in Ottawa, we've learned that the smartest solution isn't always the most expensive one. We'll tell you exactly what's wrong and what it'll take to fix it—whether that's a $150 repair or a $1,500 replacement.

Our approach: We assess first, recommend honestly, and only suggest replacement when repair won't hold up long-term. You get the facts, then you decide.

Weatherstripping & Draft Sealing

Feeling a draft? Before assuming you need new windows, check the weatherstripping. Ottawa's freeze-thaw cycles are brutal on seals. Replacing worn weatherstripping can dramatically reduce drafts at a fraction of replacement cost.

  • Works with existing windows
  • Usually completed in one visit

Repair or Replace? Here's How to Know

We'll give you an honest assessment, but here's a general guide to help you understand when each option makes sense.

Usually Repairable

Save money with targeted repairs:

  • Foggy/cloudy glass (seal failure)
  • Cranks that won't turn or catch
  • Windows that won't stay open
  • Drafts around the edges
  • Locks or latches not working
  • Minor frame damage
  • Broken balancers (hung windows)

May Need Replacement

When repair won't be enough:

  • Rotted or severely damaged frames
  • Warped sashes that won't seal
  • Multiple failed components
  • Obsolete parts unavailable
  • Single-pane windows (upgrade opportunity)
  • Repeated seal failures
  • Major structural damage

Common Window Problems in Ottawa

Our climate is tough on windows. Here's what we see most often.

Foggy or Cloudy Glass

Moisture trapped between panes means the seal has failed. Very common after 10-15 years, especially with Ottawa's temperature swings.

Usually fixable with seal replacement

Stuck or Stiff Cranks

Casement and awning windows rely on crank mechanisms that wear out over time. Often just needs lubrication or a new operator.

Quick hardware fix in most cases

Cold Drafts

Air leaking in around window edges is often weatherstripping failure, not window failure. Our winters accelerate seal deterioration.

Weatherstripping usually solves it

Condensation Inside

If moisture forms between the panes (not on the surface), the sealed unit has failed and should be replaced.

Sealed unit replacement needed

Won't Lock Properly

Lock mechanisms can wear out or go out of alignment. Usually a simple repair or adjustment—not a window problem.

Hardware replacement or adjustment

Won't Stay Open

Hung windows use balancers (springs or spirals) to stay open. When these fail, the window drops. Replacement balancers fix it.

Window Questions We Hear Often

How much does it cost to fix a foggy window?

Sealed unit replacement typically costs 30-50% less than a full window replacement. Exact pricing depends on the size and type of glass, but we'll give you a firm quote after seeing the window. Many homeowners are pleasantly surprised at the savings.

How long does a window repair take?

Hardware repairs are often completed same-day. Sealed unit replacements require ordering the glass to your exact specifications—typically 1-2 weeks. Full window replacements depend on product availability but usually 2-4 weeks from order to installation.

Should I repair or replace my windows?

If the frame is solid and the issue is isolated (foggy glass, bad hardware, worn weatherstripping), repair usually makes sense. Replacement is better when frames are rotted, warped, or when multiple components have failed. We'll give you an honest assessment.

Do you work on all window brands?

Yes. After 55+ years, we've worked on just about every brand and style. We stock parts for most common windows and can source specialty parts when needed. Bring us your old crank or hardware—chances are we have or can get what you need.

Is there a charge for estimates?

No. We provide on-site assessments for window repairs and replacements throughout Ottawa. We'll tell you what's wrong, what it'll cost to fix, and whether repair or replacement makes more sense—no obligation.
