Replacing your windows is a major investment — and in Ottawa’s climate, mistakes can become expensive very quickly.
Before choosing a contractor, here are the most common window replacement mistakes Ottawa homeowners should avoid.
1. Choosing Based on Price Alone
The lowest quote is rarely the best value.
Cheap window replacement often means:
-
Lower-grade materials
-
Poor insulation performance
-
Inexperienced installers
-
Weak warranty coverage
In Ottawa’s extreme winters, performance matters more than price.
2. Ignoring Energy Performance Ratings
Not all ENERGY STAR® windows are equal.
Homeowners should verify:
-
U-factor ratings
-
Solar Heat Gain Coefficient (SHGC)
-
Proper climate zone certification for Ontario
Installing the wrong performance level can reduce long-term energy savings.
3. Skipping a Written Contract
Never rely on verbal agreements.
A professional Ottawa window company should provide:
-
Detailed written quotes
-
Product specifications
-
Installation scope
-
Warranty documentation
Clear paperwork protects both parties.
4. Overlooking Installation Quality
Even the best windows can fail if installed incorrectly.
Common installation problems include:
-
Improper flashing
-
Poor air sealing
-
Incorrect leveling
-
Water intrusion issues
Always confirm the installer is licensed, insured, and experienced with Ottawa building standards.
5. Not Considering Ottawa’s Climate
Ottawa experiences:
-
Extreme cold winters
-
Humidity fluctuations
-
Freeze-thaw cycles
Windows must be selected and installed with local weather conditions in mind.
