Starting your window project? Ten key considerations to get it right

Replacing ageing windows is one of the few home improvements that pays you back twice: first through immediate energy savings, and again the moment you list your home for sale. If your current windows are more than 15 years old, you aren’t just losing heat, you’re losing equity.

While the sea of options can feel overwhelming, making the right choices today transforms a daunting construction project into a lifetime of quiet comfort and curb appeal.

In this article:

If you plan to live in your home for a long time or want to make sure your home will be in great shape if you plan to sell in the future, there are a lot of factors that you should consider. You don’t want to be stuck with a purchase that you or a future buyer may not be completely happy with.

1. Evaluate function & environment

Replacement is your one chance to fix functional flaws. Don’t just replicate what's there; evaluate how each room works. You can swap a protruding casement window that blocks your deck for a hung unit that saves space, or choose an awning window that allows for fresh air even during a downpour. By matching the right function to your local climate and floor plan, you transform a static wall into a strategic tool for air quality, convenience, and year-round comfort.

2. Installation type:
(retrofit vs. full-frame)

This is the most critical technical decision in your project, and it depends entirely on the health of your home's structure.

    Retrofit (Insert)

  • If your existing window frames are sturdy and rot-free, a retrofit allows you to keep your original interior and exterior trim. It’s faster and more budget-friendly, as the new window simply "slips" into the old opening.
  • Full-frame

  • If you have water damage or want to change the window's size, a full-frame replacement is the only way to go. It involves stripping the window down to the rough wall studs, allowing for superior insulation and a "like-new" structural seal.

3. Consider energy efficiency
& in-home comfort

Energy efficiency isn't just about a lower utility bill—it’s about eliminating that "cold shoulder" feel when sitting near a window in winter. To get the best return on investment, look past the marketing and focus on two key numbers:

    U-Factor

  • This measures how well the window prevents heat from escaping. The lower the number, the better the window is at keeping your furnace’s hard work inside.
  • Solar Heat Gain Coefficient (SHGC)

  • This is about control. In cold climates, you might want a higher SHGC to let the sun help heat your home; in hot, sunny regions, a low SHGC is mandatory to keep your AC from running 24/7.

4. Match the style of your home

Windows are the "furniture" of your exterior; they can either elevate your home’s architecture or look like a mismatched afterthought. This is your opportunity to correct past mistakes and restore your home’s character.

    Respect the architecture

  • A modern, minimalist window might look sleek in a showroom, but it could clash with a traditional Craftsman or Victorian home. Consider how frame colours and profile depths complement your siding and roofline.
  • Grids & divided lites

  • The pattern of the "bars" in your window can completely change a home's personality. From traditional Colonial grids to elegant Prairie styles, these small details create the visual rhythm that makes a house look "right."
  • Colour as a tool

  • Don't feel restricted to basic white. Darker frames, like black or bronze, can create a stunning "picture frame" effect for your view, while wood-grain finishes offer the warmth of nature without the high maintenance of real timber.

5. Pick features & options

Once you’ve settled on the style, it’s time to customise. These "finishing touches" are what bridge the gap between a standard window and a high-end home upgrade.

    Hardware finishes

  • Think of hardware as the jewellery for your windows. Matching your locks and cranks to your home’s existing interior hardware,like brushed nickel, oil-rubbed bronze, or matte black, creates a cohesive, designer look.
  • Glass technology

  • Beyond efficiency, consider your lifestyle. Laminated glass can significantly reduce outside street noise, while tempered glass is a safety must-have for windows near floors or doors.
  • Ease of cleaning

  • If you have windows on a second story, look for features like "tilt-in" sashes. This allows you to clean the exterior glass from safely inside your home, eliminating the need for a ladder.

6. Think about security

Windows are a primary entry point, so their security features should never be an afterthought. Modern windows offer far more than a simple latch.

    Multi-point locking systems

  • Unlike a single centre lock, these systems engage at multiple points along the frame with one handle, making it nearly impossible to jemmy the window open from the outside.
  • Frame reinforcement

  • High-quality vinyl or composite windows often feature metal-reinforced meeting rails. This adds structural "backbone," preventing the frame from being easily pried or bent.
  • Impact resistance

  • If security is a top priority, consider impact-rated glass. It’s designed to withstand forced entry attempts (and extreme weather), providing peace of mind whether you’re home or away.

7. Choose a qualified installer

The best window in the world will fail if it’s installed poorly. Every company has a different philosophy, and getting at least three quotes isn't just about price; it’s an education. Each consultation will reveal new details about your home and available options. When you’re ready to vet your finalists, dive deep into these categories:

    Check the company’s reputation

  • Don’t just look at the star rating; read the specific reviews. Look for mentions of how they handled problems or clean-up. A company that stands by its work in the face of a challenge is worth its weight in gold.
  • Consider company stability

  • How long have they been in business? You want a company that has been around longer than the warranty they are offering. A "lifetime warranty" is useless if the company disappears in three years.
  • Do your performance homework

  • Go beyond the sales pitch. Visit Energy Star or the NFRC website to compare the actual performance ratings of the products they are quoting. This ensures you’re getting the efficiency you’re paying for.
  • Verify professional credentials

  • Ask for proof of industry-specific certifications like SAWDAC or Window Wise. These credentials indicate that the company adheres to strict installation standards and ethical business practices.
  • Ask the "what-if" questions

  • Clarity prevents "invoice shock." Specifically, ask: "If we find rotten wood in the frame after the old window is out, how is that priced?" Knowing the cost of unforeseen repairs upfront keeps the project on track.
  • Confirm disposal and hidden fees

  • Ask if the quote includes a window disposal charge. You don't want to be left with a pile of old glass and frames on your lawn or a surprise fee on the final bill.
  • Know who is in your home

  • Ask if the installers are full-time employees or subcontractors, and how they are compensated. Hourly-paid installers are often more motivated to focus on the fine details of a thorough job, whereas those paid "by the window" may be incentivised to rush.

8. Get comparative quotes

When buying windows, it’s just natural to want to get the best price you can, especially if you are replacing all the windows in your home. Unfortunately, there’s more to shopping for new windows than price. The lowest price may not be the best value. There are lots of things to consider.

9. Check the warranty

You can have the best windows in the world, but if those windows are installed incorrectly, you could be dealing with water damage, heat loss, bug infestations, airflow issues, and a general loss of comfort throughout your home. In many ways, the most important part of buying windows is the warranty.

Many window companies in and around the Ottawa area claim to have the best window warranty in the business. Unfortunately, the warranty language is often vague, misleading or full of fine print that is difficult to interpret. Every window company is different, and even companies that sell and install the same product will have differing warranties.

10. Scheduling, lead times,
and the "grant effect"

When researching your timeline, it is important to consider the impact of government incentive programs. Even when specific federal or provincial grants are closed to new applicants, they continue to influence lead times across the industry. During active grant cycles, a massive surge in demand for high-efficiency, Energy Star-certified windows can create significant manufacturing backlogs.

Furthermore, homeowners finishing existing grant journeys must meet strict completion deadlines (often year-end), which can lead to a "seasonal rush" that fills up installation schedules months in advance. To avoid these bottlenecks, we recommend starting your investigation early to secure your place in the queue, regardless of your current program status.
