Lately, we’ve heard from many homebuyers who are surprised that their builder-installed windows are starting to have issues early on. Some homes are less than a decade old! So one of the most common questions we get is how long do windows last?

Well, with Weather Tight, our answer is a lifetime. Our windows are backed with a lifetime warranty—and if you sell your home, the new homeowner is covered, too. Here’s what you should expect from quality windows and how to tell if your windows were built to last.

Builders Don’t Make ‘Em Like They Used To

Let’s be honest—many builders are trying to get developments up quickly. They want the homes to look nice to attract buyers, and then they move on. They’re not concerned about the long-term comfort and craftsmanship of your new home.

Many developers and contractors are also trying to save on building costs. As a result, they might buy mass quantities of windows, doors, and other building supplies, without considering the custom installation requirements and slight variances in the product. As a result, many new homes feature cheap, lower-quality windows that might look good but aren’t built to last.

Sometimes the contractor has skimped on the insulation around the window (or skipped the insulation altogether). Sometimes the window frame isn’t well-tucked or finished. Other times cheap windows can stick, be hard to open and close, or experience seal failure. Homeowners might see moisture in between the glass panes or feel air leaking in around their windows.

We see homes built in the nineties, early aughts, and even within the last decade that already need replacement windows. In contrast, we’ve worked on 100-year-old bungalows with windows that have aged relatively well and are just now starting to wear out. See why one homeowner decided to replace it below.


Don’t wait to replace your windows. In this episode of Home Improvement Tips with Tod and Todd, see why one homeowner wishes she would have made the decision to invest in replacement windows sooner:


So how long do windows last? It’s not about the age of the windows or the home; it’s about the quality of the windows, the dedication of the installer, and the customization to ensure the window fits the space.

How to Tell Your Windows Need Replacement

There are many signs that it’s time to replace your windows. The biggest is your comfort. If you reach for a sweater, slip on socks, or constantly adjust the thermostat, you may be experiencing air infiltration from your windows. Dampen your hand with some water and feel the air around the edge of your windows—do you feel a cool draft? That’s a sign that air is getting in your home (and you’re paying higher energy bills to compensate).

Another sign that your window needs to be replaced is the appearance. If your window gets foggy between the panes of glass, the seal has failed. All windows get some condensation (especially if you cook, shower, or run a humidifier in the winter), but the condensation shouldn’t be in between the glass.

Look at the window trim and frame. If it’s cracked, bubbling, or mildewing, that’s another sign that the window needs replacement. Older windows will naturally get loose as the seal starts to degrade. If your house rattles in the wind or your window frames look shabby, it’s time to consider window replacement.

You shouldn’t have to think about your windows most of the time. You shouldn’t lose sleep over the safety of your windows. You shouldn’t have to wrestle to get them open or closed, climb a ladder to clean them or fight with locks to ensure their security. Windows should never slam down like guillotines or present a hazard to children and pets.

Why Window Replacement Is a Worthy Investment

As a homeowner, you probably monitor the costs of care and maintenance. If you live in a newer home, chances are you assume that the house shouldn’t require any replacements for a while—most buyers expect that the windows, doors, roofs, and other components will be durable. But as mentioned above, unfortunately, that’s not always the case.

If you have an older home, you’re probably concerned with costs too. After all, older homes can seem like there’s always something to fix or update. Replacement windows are an essential investment to consider because they offer a significant impact and can save you considerable money down the road. They’ll increase the value of your home, the curb appeal, and efficiency—making them well worth the effort.

If you’re considering replacement, you may base your choice only on the cheapest offer or even consider a DIY window replacement. Unfortunately, many of these cheaper options are pennywise and pound-foolish. You may save money at first, but your windows will not include a lifetime guarantee. Many installation companies turn over quickly. Very few have been around for 35 years, like Weather Tight. Without professional, reliable installation, you may run into the same issues (or worse) quickly.

Why Weather Tight Windows Are Different

At Weather Tight, our windows are custom-built to fit the exact space. Each home is slightly different, and variations will occur, even in standard builds, condos, and large developments. Houses can settle over time, and there may be subtle differences. Windows aren’t a one-size-fits-all solution.

What’s more, each homeowner is different too. Some homeowners may have a distinct style, want something that matches their interior trim, or compliments the exterior of their home. For example, you may want to change out a double-hung window for a bay window in the living room or even make a sliding window larger for a more expansive view.

When you select replacement windows from Weather Tight, we’ll help you find the perfect window to complement your style, meet your needs, and beautify your home. We have many different trim options and colors available. Durable vinyl frames are maintenance-free and will look new for many years to come.

Our triple-pane windows are filled with inert argon gas that acts as an insulator, helping you keep your indoor temperatures steady and comfortable. As a result, many of our customers are surprised at the difference in their energy bills and comfort levels inside their homes. One of the most common things we hear is, “I wish I’d done this sooner!”

So if you’re considering replacement windows, don’t wait. If you’re wondering how long windows last or how long windows SHOULD last, chances are you’re experiencing dissatisfaction with the windows in your home now. Window replacement is an excellent investment in your long-term satisfaction and happiness with your home.
