Aside from a bit of glass cleaner and a weekly wipe, you really shouldn’t notice your windows. Windows let light into your home and add character to your castle. But if you start to notice condensation, drafts or rattling noises from your windows, it’s time for an upgrade.

Why replace your windows?

Gone are the days when a new kitchen or bathroom would wow a buyer into overlooking importance household components such as windows. In fact, whether or not windows have been upgraded is one of the top five inquiries made by potential buyers. And why not? On a typical 3-bedroom home it can cost anywhere from $6,000 to $10,000 to upgrade to basic, weather-efficient slider/picture windows—throw in custom, non-standard white frames, or unique features and prices start to jump even higher.

The good news is that investing in new windows really can create curb appeal and with the right choices or some simple design finishes, it can make a dated exterior look fresh and appealing.

How to tell if you windows need replacing?

Here are some telltale signs that your windows need replacing. If you notice:

**Drafts
**Condensation and fogging
**Rot or mould
**Cracked caulking

What to know when buying a new window?

When buying new windows, you’ll want to remember: High/Low. High is for high R-value, which determines how well a window prevents heat loss. Low is for low emissivity—otherwise known in the industry as Low-E—and this is the method windowmakers use to reflect the heat to the warm side of the glass (so in cold weather heat stays inside and in warm weather heat stays outside).

What options do I have when it comes to installing windows?

You have two choices when it comes to window installation: retrofitting (inserting new windows into the existing casing) or brick-to-brick (stripping out the windows and frames and starting fresh).

Retrofitting is typically less expensive, but brick-to-brick is typically the more energy-efficient option. That said, this rule of thumb isn’t always the case.

For instance, if you live in a home built pre-1950, you will want to seriously consider not replacing all your windows. That’s because you probably have window frames built out of old-growth wood—a much more resilient wood that as superior rot and warp resistance and holds paint much better than newer wooden frames. Now, after costing out the retrofitting of these old-growth frames with new low-E glass, you may find there’s not much difference than if you were to replace with new vinyl-framed windows. The difference, however, will be in your home’s curb appeal. Unless you upgrade—and pay the steeper sticker price—new windows just don’t have the charm, character and warmth of old-wood frame windows. Ripping out the old windows, then, could seriously impact the value of your home.

Does that mean you can’t get efficient windows in an old home? No. A number of studies were conducted over the last decade and each came to the same conclusion: There is very little difference in the heat efficiency between a brick-to-brick new window replacement and a retrofitted window combined with a storm window, as long as the windows were low-E.

What types of windows can I get?

This is the fun part. Regardless of whether or not you retrofit or replace, you can opt for a number of different types of windows. Here are descriptions of the most common types of windows:

Casement
Swinging in and out like a door and operating with a crank, they offer a high level of ventilation and have a tight seal when closed. This is a great choice for hard-to-reach or awkward places because they’re easier to open.

Double-hung
These windows consist of two sashes that move up and down. They are great for ventilation and complement any style of home—although are really popular with retrofits and upgrades on older homes.

Picture
Large and fixed they can also be flanked by two casements or double-hung windows on either side. Because of their big, dramatic shape picture windows let in lots of natural light and provide unobstructed views—which is why the price tag for these windows is quite a bit higher (and why they are used as a statement on a house, not for every room). When planning to use a picture window in a room, remember that these windows, by themselves, do not offer ventilation.

Bay
Made up of one large fixed window in the middle and a casement on either side, they project from an exterior wall and are a staple in many Victorian-style homes. If you’re planning on installing a bay window, you will need to talk to a structural engineer, as these windows are quite heavy often require additional structural support.

What else do I need to know about replacing windows?

Many people don’t realize it, but in just about every city in Canada, if you’re installing a new window where one didn’t previously exist or enlarging an existing window opening, you will have to get a building permit.

  1. Thanks for the great article! A good chunk of the homes near me are more than 50 years old. I wish more people would keep the older window frames. It creates a nice atmosphere and you can still have an energy-efficient home with them.

  2. Your tip about high/low is very important to remember when replacing your windows. In the summer, high R is helpful when trying to keep your home cool, but low E comes into play in the winter to keep the heat from seeping through the windows. With the skyrocket developments in technology, being sure to put those developments to use to make more energy efficient windows in incredibly helpful. http://kcglassinc.com/

  3. I am so glad that I saw this article! I was pretty confused with what to do with my window. I have been thinking for quite some time about getting my windows replaced. I am from Toronto and here it’s very cold during the winter. So I thought I’ll go with the energy efficient windows. I contacted the salesman at Landmark home solutions. My current windows are almost 10 years old. I’ll get the replaced soon! :) Keep Writing!

  5. We have one window in our home that definitely has a draft. I didn’t know if it was just because it was getting a little colder outside. Now that I know that it is a sign of needing a replacement window, I should probably get on that. Especially before it gets even colder. We want our home to stay nice and warm. Thanks for the tips on replacing windows. I appreciate it.

  6. Our windows seriously need an upgrade. We bought our house last year, and we were not aware of just how energy-efficient the windows were. We have paid very high costs of heating this winter and we won’t make the same mistake again. http://hardwareplusinc.com/window-and-screen-repair.html

  7. Thank you for the help. I have a window that lets in a serious draft and it has caused my heater usage to go up. I had not thought of that as a reason to replace the window, but it may be worth it. How can you tell if it is serious enough to need replacement? http://www.stevensglass.net.au/order-online

  8. I have had drafty windows and doors in some of the places I lived in. Something you mentioned that I wish I would have known about what the R-value of a window was and the Low-E value of windows. I thought all windows were same, just some were thicker than others. Thanks for all the great tips on replacing windows!

  9. I have a draft coming in through my window and so I have been thinking about getting it replaced. I don’t want to end up paying more on my energy bill because of it! I know I would once winter comes because I get cold easily enough already!
