1. Incorrect Measurements
Why It’s a Problem
One of the most frequent mistakes in window installation is incorrect measurements. Even a small miscalculation can result in gaps around the frame, leading to air leaks, water infiltration, and higher energy bills.
How to Avoid It
- Always measure the width, height, and depth of the window opening at multiple points.
- Account for settling and shifting in older homes, which can cause slight variations in dimensions.
- Work with professional window installers who have experience in precise measurements.
2. Poor Sealing and Insulation
Why It’s a Problem
Windows that are not properly sealed allow cold drafts in winter and hot air in summer, forcing your HVAC system to work harder. Moisture can also seep in, causing mold growth and wood rot.
How to Avoid It
- Use high-quality weatherproofing materials, such as foam insulation and caulking, around the window frame.
- Ensure the window is level and tightly secured before applying sealants.
- Hire an experienced installer who understands how to properly seal windows for Alberta’s harsh climate.
3. Using Low-Quality Materials
Why It’s a Problem
Some homeowners opt for cheap materials to cut costs, but this can lead to poor insulation, shorter lifespan, and frequent repairs.
How to Avoid It
- Invest in high-quality vinyl that offer better durability and energy efficiency.
- Choose Energy Star-rated windows, which provide better insulation and reduce energy costs.
- Work with a reputable window replacement company that offers warranties on both materials and installation.
4. Ignoring Local Building Codes
Why It’s a Problem
Each region has specific building codes that ensure windows are installed safely and efficiently. Ignoring these regulations can lead to fines, safety risks, and problems during home resale.
How to Avoid It
- Work with a licensed window installation company that follows all local and provincial regulations.
- Ensure your windows meet Alberta’s energy efficiency and safety standards.
5. Improper Flashing Installation
Why It’s a Problem
Flashing is the barrier that prevents water from seeping around your windows. If installed incorrectly, it can lead to leaks, mold, and structural damage.
How to Avoid It
- Use high-quality, weather-resistant flashing materials.
- Ensure flashing is installed under and around the window, directing water away from your home.
- Hire professionals who understand proper flashing techniques for Alberta’s climate.
6. Rushing the Installation Process
Why It’s a Problem
Some contractors rush through installations to cut costs and save time, leading to poor alignment, improper sealing, and future issues.
How to Avoid It
- Choose a trusted window installation company with positive reviews and a proven track record.
- Don’t rush the process—proper installation takes time to ensure long-term performance.
- Inspect the installation before signing off on the project.
7. Not Considering Climate Factors
Why It’s a Problem
Alberta’s harsh winters and hot summers require windows that can withstand extreme temperature fluctuations. Installing the wrong type of window can lead to poor insulation and increased energy bills.
How to Avoid It
- Choose double- or triple-pane, Low-E coated windows to improve energy efficiency.
- Ensure your windows are rated for Alberta’s climate to prevent expansion, warping, or cracking.
- Work with local window installers who understand regional weather challenges.
8. Hiring Unqualified Installers
Why It’s a Problem
Inexperienced or unlicensed installers often cut corners, leading to improper fitting, weak seals, and structural damage.
How to Avoid It
- Always verify that your contractor is licensed, insured, and has strong customer reviews.
- Ask for references and examples of previous installations.
- Choose a company that offers a warranty on both windows and installation.
