So your windows are crappy. In Edmonton, unless your windows are relatively new, they probably suck. This city gets too cold to be leaving old windows in those giant square holes in your walls. You should really get new ones. So, read on to know what to consider when replacing windows.

New windows can increase the value of your home significantly

So this is the number one reason why you haven’t replaced you windows yet. I know it is. Windows are expensive, they really are. Depending on how many different sizes you have, materials you use, manufacturer,  and features you choose window prices can well over 10% of the cost of your home. On the other hand, people often spend that much on kitchen renovations alone and whereas having a sweet kitchen is really great, new windows can not only increase the value of your home significantly, but also make your life indoors much more enjoyable.

You’re going to open and close your windows a lot and some windows are pretty flimsy so they won’t hold up to any sort of abuse. When choosing windows think about who will be using them – if you’re going to have renters, or kids, choose carefully. You don’t want to be replacing latches, locks, pulls and window operators all the time. Some windows also sag over time because of their design or materials. Wood windows can shift and tall, wide windows can bind in their openings. Typically, PVC windows will hold up well against Edmonton sun and snow, but some cheaper vinyls can crack and dry out. As with anything, you often get what you pay for, so if you’re planning on spending a long time in your home, take that into account as well.

Most people don’t know that there are only a few kinds of windows that meet egress guidelines for bedrooms. Windows have to open up easily without any special knowledge or tools very easily in an emergency situation (like a fire). Unless you have a sprinkler system in your home (not the one on your lawn), you probably need to have sliding windows in the bedrooms. On the upside, these are the cheapest windows, so maybe that’s not such a bad thing. Consult your window company to make sure everything is safe and up to code before you buy anything. Most companies will tell you if something is legal or not, but not everyone will give you the heads-up.

Perhaps you have a wicked old house and you don’t want plasticky shiny windows in your home – I feel your pain. It’s hard to take out beautiful wood windows even if they do nothing for your heating bill. What can you do instead? Well you could get storm windows that cover your old windows, but these are usually a stop-gap – replacement still works best. Typically what people do now is get a vinyl window or a vinyl/wood window hybrid designed to match the style of the home and replace the older windows with that. This mean you can get the same look without the same poor insulating factor. Be warned though, this is for people who have a buttload of cash. These windows cost the earth, but that’s because they are much more customized than other windows are.

If you have a newer home, be sure to still think about how everything will look when your windows are installed. Be wary of coloured frames like beige and brown – they won’t be in style for long and may not match changes made to the exterior of the home. Often white is the best colour to go with and likely the least expensive as well. And besides how they look, window function is important. Awning windows allow you to open a window even if it’s raining outside, but they don’t offer the best ventilation. Casement windows are meant to catch breezes, but are subject to warping, sagging and operator trouble. Sliding windows are great, but offer a half the ventilation of hinged windows. All these things are very important, so be sure you’re up to speed with what’s available. There’s nothing worse than getting the wrong thing for your home – and believe me, there is a right and a wrong window for some places.

Stick with double glazed windows for older homes. This should be a huge improvement – and enough to keep them from frosting up in Edmonton’s cold winters.

These days, windows have an airspace between two or three panes of glass. This keeps heat in in the winter and out in the summer. Insulated glass units or sealed units have revolutionized the R-values of windows. But be careful not to overdo it either; put it this way, if you have 2×4 walls, you don’t need triple glazed windows – the walls will be colder than the glass – it just isn’t necessary. Typically its best to stick with double glazed windows (2 panes of glass) for older homes. If you have a new home with 2×6 walls and are thinking of installing triple glazed windows, that makes more sense because the insulation in the walls will more closely match the insulating factor of the windows.

For a number of years now special coatings on window glass have been available. There are a lot of options so I won’t go into all of them, but basically you can get a cheap one and an expensive one. The more expensive coating is like having another pane of glass in the window and keeps heat from entering in the summer by reflecting ultra-violet light and infra-red light. This can be pretty nice when you don’t have air conditioning, which few people have in Edmonton. Most windows will come with a low-e coating automatically, but be sure to ask which one and ask what that means. For example, you don’t want to be cooking in front of  a south facing window for no reason. On the other side of the house, you’ll have a north facing window which really needs no coating. Perhaps there is some savings in considering this when you’re looking to replace your windows.

If you don’t mind having smaller windows than before, you can get insert windows

Replacing old windows means old junk comes out and new shiny stuff goes in. But not everything has to come out. If you don’t mind having smaller windows than before, you can get insert windows that just slot into the original frame. This costs less even though the installers will have to cap your old outside frame with aluminum to match it to your new windows. If you want everything to be new, however, a full frame change is the best way to go. That means all the old wood frame will also be torn out and replaced with new stuff. And as an added benefit, your window opening will be a little larger than they would be if you just stuck inserts into the existing frame. Be sure to weigh the pros and cons when you choose which way to go.

Windows are important. I’ve seen some really poor examples showing homes in Edmonton. Few things make a house look worse than crap windows that rattle in broken tracks. During an Edmonton winter, some windows will be so frosted up that you can’t see through them for months. Don’t forget, there are windows for a reason. You might want to actually see what it’s like outside, get some natural light and not feel like you’re living in a cave. All great reasons to get some quotes and replace your windows.

Why are my windows fogging up in winter? What did I do wrong? This is a complaint I hear from new home buyers all the time.

As it gets colder out, people may notice that their windows are icing up on the inside. This is especially true in a winter city like Edmonton. This can be a frustrating situation because you can’t seem to defrost them or get rid of the ice – it just keeps coming back. There might be days that you may not even be able to see out of your windows at all.

Fortunately, in most cases, it’s not as bad as you think. There are four main causes to windows frosting up in your home: temperature, humidity, the quality of the window installation and air circulation. Let’s take a look.

Ever noticed that it doesn’t matter how hot it is in the summer, your windows never get any condensation on them? That’s because warm air can hold a lot of moisture – so it doesn’t stick to anything – it just floats around in the air, happy to be suspended. However, drop the temperature a bit and you might notice that your windows will fog up – drop it a lot and they ice up completely. The colder it gets outside, the more likely your windows are to fog up and if it’s cold enough, they’ll frost up no matter what you do. This is the same situation that causes car windows to frost up in the winter. Warm air during the day has moisture in it and as the air cools, the moisture leaves the air and sticks to any surface it is touching allowing them to fog. Just because your house is warm doesn’t mean your windows are – but more on that later.

How To Fix It

Well this one you can’t fix. The temperature is what it is outside. But read on to learn more about the factors that you can control.

A good example of how humidity causes condensation in every day life is on the bathroom mirror. After a shower, a bathroom mirror is often fogged up. That’s because the humidity in the bathroom is off the charts, the air just can’t hold onto the moisture anymore – so it sticks to the walls, the mirror, the shower door, everything. This level of humidity is not going to be found in the rest of the house, but in the bathroom when a hot shower has been running – it’s a foggy situation.

Any water source in the house has the potential for evaporation, and consequently, high humidity and condensation on your windows in winter is the result. Plants give off moisture during the evening and watering the plants means pots of moist soil that can release water into the air. Cooking and steaming things on the stove also produce moisture and of course showers and baths will release a lot of water vapor into your home’s interior. What that all means is that when things cool off, you can end up with frosty windows.

How To Fix It

Well some causes of high humidity in the home are quite easily fixed – others are not. The easiest thing to do is if you have a forced air furnace and a whole-house humidifier is to turn down the humidity. Humidity may have to be at about 20% in the winter time if it’s -20-degrees out to keep those windows from frosting up – depending on how insulated your windows are. Here is a handy chart that shows what the humidity level is possible in a building before the windows will fog up or frost up:

So in the above chart, you can see what your windows can handle for humidity before they start to ice up. Triple glazed windows can handle a fair bit more humidity than double glazed windows – they have more insulation. Windows that are older sliding units that have two sets of panes cannot handle much humidity at all and will likely ice up at some time during the winter no matter what, and single pane windows are pretty impossible to keep clear.

If you live in Edmonton and don’t have at least two panes of glass between you and the elements, it’s time for new windows. For more on condensation, see this publication from the City of Edmonton. There are other things that add humidity to the house besides your furnace humidifier, however. Here are some specific things that can contribute to higher humidity home.

Clothes Dryer

For example, if you vent your clothes dryer into the home instead of outside, you’re going to have a large amount of humidity inside that you wouldn’t normally have. This can be fixed by running ducting outside your home and having all dryer air and moisture removed from the home. If you can’t get ducting to the outside, you can install an exhaust fan to try to take most of the moisture out.

Cooking & Bathing

A lot of every day humidity in a home comes from cooking and showering. (Think about boiling a pot of water and how much humidity that creates). Also, showers create a lot of moisture – often enough to fog up the mirror in the bathroom, right? Some of that moisture is going to make its way to your windows. So, run your hood fan in the kitchen when cooking and always run your bathroom fan when showering. This can help reduce humidity before it gets a chance to migrate over to frost up the windows. If you do this, you’ll probably solve most of your everyday frosting issues.

Pools & Hot Tubs

If your humidity is coming from a swimming pool, you can cover the pool when it is not in use or install a dehumidifier in the pool room. You can also reduce the temperature of the pool water – covering and lowering the temperature of the water will keep more of the water in liquid form instead of it becoming vapor and travelling to the windows. There isn’t really anything else you can do – that pool water is going to keep getting into the air and sticking to the windows. Pool areas are notorious for having fogged up windows – whether they are in commercial areas or in someone’s home. And hot tubs are the same – only worse. A hot tub should be covered any time it is not in use. Triple pane windows are also recommended for any pool or hot tub areas. And when it comes to commercial style framing for windows (the aluminum storefront type) always make sure the aluminum is thermally broken, otherwise it’s going to attract a heck of a lot of moisture and ice up very quickly when the temperature drops outside.

It should be noted that there are sometimes reasons to keep the humidity high in a house in winter. Being dry in the winter can sometime feel uncomfortable for the occupants – especially at night. If you have a hardwood floor, letting the humidity drop too low will make the floor shrink and get creaky. This should return back to normal when the humidity rises, but it does have the potential for causing cracks or splits in certain floor boards. So balance the need for drier air with your own need for moist air and you house’s need for humidity for it’s ‘woody’ components.

The last situation that can occur to make windows fog or frost up in the winter time is poorly installed windows. If insulation is not properly installed around the windows and they are just trimmed up with an empty cavity surrounding them, cold air will leak in around the window making the glass very cold on the inside where condensation will become ice. Another window quality issue is worn out weatherstripping that allows cold air to infiltrate the window area and to make the glass cold enough for water to condense on it. Poorly sealed windows can allow cold air to blow right across the pane of glass.

How To Fix It

This insulation issue is something that may be easily fixed with some spray foam or even batting insulation stuffed in the void between the rough opening and the window casing. Check with your window installer to see if this has been done. Or, if you’re handy and feel like doing a little checking yourself,  you can gently pry the window trim off and take a peek inside to see if the windows have been properly insulated around. If they haven’t, it’s a pretty cheap fix. If they have, well then you have other issues and might want to start back at the beginning by checking your humidity levels in your home or seeing if the weatherstripping is not doing its job. If your weatherstripping is old, consider replacing it. It might not only keep your windows from frosting up, but also save you some money on your heating bill!

The last issue concerns window treatments or coverings. If you have heavy drapes, blinds or shades covering your windows, you’re going to trap cooler air near the glass. This means when moisture sneaks back there and is trapped with the cold air, it’s going to stick to the windows. As an aside, this is also one of the quickest ways to ruin your window trim because the ice that forms on the glass will melt when the sun comes out and run down, sitting on the sill and peeling the paint or and rotting the wooden trim or even the windows if they are wood windows.

How To Fix It

Simply open your blinds and let the air circulate through to warm up your windows. Ever noticed how heat registers are located in front of windows? Well that’s partly because windows can be a bit drafty, but also it keeps air flowing over the glass and keeps those windows frost-free.

Maybe you don’t think it matters if your windows fog up. Well, that depends on what kinds of windows you have. If you have a window that is all PVC (vinyl), then not much will go wrong with it, you’re just going to have icy windows. And aluminum windows may be perfectly fine too – depending on what kind you have. But if there is any wood around your window (and let’s be honest, your entire home is probably made of wood), then you can end up with a rotten window sill or trim by not taking care of your moisture issue. Remember, water is what really wears out houses, so you have to keep things dry at all times. Rotten window sills and trim look ugly and will have to be fixed because rotten wood can be structural problem, eventually. Your windows may sag or even fall out if your sills are rotten – I have seen it happen!

Speaking from personal experience, we used to have windows that iced up so much that we couldn’t see out of them for about four months of the winter. This is pretty annoying when there is not much sunlight in the winter as it stands and much of it was being blocked from coming in the windows. Not cool. For us, this was a combination of old windows letting cold air in, high humidity in the home and very cold temperatures outside – we do live in Edmonton after all.

So we got new windows. They’re nothing special by today’s standards – but they’re 40 years ahead of the ones we had – and window technology has come a long way. And do they ever make a difference.  We have no problems with our windows icing up now, so I know that they were installed correctly and are a good fit for our house. It has been 30 below 0 (that’s -22 Fahrenheit for y’all down south) and there has not been any icing up around the windows at all. A simple fix, and actually not a very expensive one – and we have a lower heating bill by a large margin now as well. It was really a win-win window situation for us. If you have icy windows, it might be something you can fix yourself, or it might be time for new windows – try the tips above and if they don’t work and you have to go the replacement route, see 7 Things To Consider When Replacing Your Windows.
