Old windows leak

With the summer sun heating up your Johnson County or Kansas City area home with a vengeance, it may be time to take a look at the condition of your current windows. Inefficient windows allow for heat transference that not only reduces your overall comfort level but also, if you’re running the A/C, will make its job more difficult and increases the utility bill.

According to the experts, hot and cold conditioned air escaping through poorly insulated windows can be responsible for as much as 10-20 percent of your average home energy costs. Modern technology has developed some very efficient windows to help with this problem but these windows are expensive to buy. Fortunately, there are easier, more affordable ways to affect window repair to keep the heat out.

Older homes windows on the south and west sides of your house will be the ones allowing for the most summer heat gain and should be tackled first. The place to start on these windows is to seal any gaps in and around the window frame where air is being allowed to pass. Caulk and weather stripping can be effectively used to provide a resistant barrier against air infiltration. Next, seal the perimeter around the frame where it meets the glass pane.  This may require replacing old, cracked glazing putty with new material. For windows not utilizing putty, a bead of clear silicone sealant works well for adhering the pane to the frame.

A popular window repair technique to help keep out summer heat is to apply a reflective film designed to reduce the amount of radiant sunlight able to pass through the glass. This film is usually tinted and may be what’s called low-emissivity or low-e. A low-e film, which is an important component of many of the new double- or triple-pane windows now on the market, can be applied to single-pane window glass to improve its reflective abilities and reduce its absorption characteristics.

A less-popular but highly effective means of reducing heat transference through windows is to apply aluminum foil on the interior glass, shiny side facing the home’s exterior. Disadvantages of this window repair method are that all incoming light is blocked out and the aesthetics aren’t great. Adding light-colored blinds, shades or drapes will also aid in reflecting out some of summer’s heat. Effective shading can also be affected by a well-positioned shade tree near the window or the installation of awnings. 

At the end of the day if all the repairing is too time consuming or too much of a headache it can’t hurt to get a quote from a local contractor to see how much it really costs. Not only will it save you the time and headache but it will also save you a bunch of money on your energy bill. It doesn’t cost as much as you would think.
