Windows are an important part of any home: they let in the light, keep out the elements, and give you an extended view of the world. When the glass needs replacing, you must address the issue sooner rather than later. Not only can it impact the appearance of your home, it can make it less energy efficient.

On average, most homeowners pay between $160 and $353 to replace window glass, with most repairs falling around $256. Replacing double pane window glass falls on the higher range with an average cost between $350 and $400, while the price to install new glass in a front door can fall anywhere between $100 and $500. Prices will range depending on your window style, the type of glass, and labor costs.

1. Double Pane

These windows are thicker and offer better insulation. If you’re completely replacing windows, costs can shift dramatically depending on the number and size. The below chart shows costs to replace glass when the existing double pan frame is kept compared to the price including the frame replacement.

2. Single Pane

These are your most basic windows, and are typically found in older homes. Standard single pane glass can be found for as low as $3 per square foot. After labor, the cost to replace a single pane falls in the $50 - $75 price range.

3. Bay Windows

Bay window glass replacement prices depend on the size and type of glass. For the standard three-pane window, replacement ranges from $500-$1,000.

4. Bow Windows

The average five-pane window starts at about $1,000 for glass replacement. If the one in your home is particularly large, the rate may rise to closer to $3,000.

Tips for Estimating Glass Replacement Costs

There are a few things to keep in mind to ensure you get a quality replacement at a fair price.
Know your skill level. If you’ve got plenty of home repair and do-it-yourself experience under your belt, you’ll probably be able to handle doing the replacement yourself. However, it’s important to recognize your limitations. If you’ve never really been the handy type, it might be best to hire a professional who knows exactly how to get the job done right. Similarly, if you have only basic maintenance skills and are upgrading to more insulated or tinted glass that might require special installation, you should at least consult an expert first. Installing a window improperly can lead to poor sealing, drafts and gaps, or even cracking. Avoid causing problems (and even more expenses) later on by underestimating your abilities now.
If you're going the DIY route, in addition to the glass itself, you will need a variety of tools and supplies, including a glass cutter, razor blade scraper, and heat gun. Unless you have these supplies on hand, you can expect to spend another $100 to $200 on supplies alone. But if you believe you can do the job yourself and already have most of the materials on hand, you can make the repair for just the cost of the glass.

Tools and Supplies You'll Need

  • Work gloves ($10)
  • Glass cutter ($5)
  • Razor blade scraper ($8)
  • Paint ($10)
  • Putty ($12)
  • Paintbrush ($7)
  • Putty knife ($6)
  • Chisel ($12)
  • Glazier points ($5)
  • Pliers ($9)
  • Glass of proper size ($100-$630)
Shop around. Plan to compare prices for both materials and labor. Online reviews can be excellent resource to find out about prices and contractors in your area. Keep a running list of estimates you receive, then compare them with the customer feedback you’ve found. Remember: often, it’s best to spend a little more money if you know the job will be done correctly. Weigh the pros and cons of upgrading. There’s always going to be a “cheapest option,” and window glass is no different. Consider, though, that the benefits of upgrading to more energy efficient glass are often well worth the investment. Energy Star qualified windows can save the average homeowner up to about $465 a year in heating and cooling costs. Plus, it can make your home feel much more comfortable throughout the year.

Reasons to Replace Broken Window Glass

If the glass is beyond repair, replacement will be necessary. The most common reasons to replace window glass are because the pane is cracked, because the pane is no longer transparent or because the homeowner wants to upgrade to a more efficient type of glass. Most glass replacements are done because a window has been damaged in some way, which could be due to a storm and high winds, a falling branch, or even a stray baseball during a neighborhood game. In some cases, the glass won't get clean. Although this only tends to happen with double or triple paned windows, it may still be a problem. No matter how much the glass is cleaned, it can still have streaks, condensation or other marks that detract from the home's overall curb appeal, and can potentially ruin the view from the interior of the house.

Benefits of Glass Replacement

Some of the advantages of replacing the glass in a window include an immediate solution to a broken pane, the affordability and the opportunity to upgrade the home. Replacing the entire window, which includes the frame as well as the sash, will be a much lengthier process than simply replacing the pane. Plus, a simple glass replacement is often much less money than replacing the entire window. Even if the actual window is a specialty design, an older frame or anything else that may be pricey to replace, the glass should not be expensive unless it is a customized shape.Glass replacement can be an easy way to upgrade the panes to something better. Over time, older windows may let in air from the outside and start to transfer temperatures, which reduces energy efficiency in the home. This is not only a problem for the environmentally conscious but also a problem for anyone seeing an increase in their monthly utility bills. Because there are so many different types of glass windows on the market, it is up to each homeowner to determine which type of glass is the best for their home. One of the advantages of glass replacement is that homeowners can upgrade to any of the following options:
  • Low-E glass to minimize solar warming in the home
  • Argon glass to increase energy efficiency
  • Tempered glass to prevent future damage to the pane
  • Designer glass for an attractive look

Steps to Replace Window Glass in the Home

Replacing the glass in a window doesn't always require professional assistance, but it may be best if there are several windows to do, if homeowners don't have the right tools, or if the window is unusually shaped in any way. The first step in the process will be to remove the broken or old glass. This has to be done safely with gloves and a small hammer as well as a rag to pick up the pieces of glass that fall in the process. Then, the frame can be cleaned and any old putty removed from the edges. If there is any old caulk stuck to the frame, this has to be scraped off to ensure a tight fit for the new piece of glass to be installed. The trim of the frame may have to be removed in order to facilitate this step. Then, the replacement glass can be fitted into the existing frame. It must fit perfectly, or it will need to be cut with a glass cutter to be the right size. Once in place, glazier's points, or small triangular metal pieces, can be used to hold the glass in the right spot. Then, a thin layer of putty can be applied to the edge of the frame where it meets the glass. The putty should be scraped so that it is completely flat and even. Finally, the putty can either be painted or covered back up with the existing layer of trim to match the rest of the windows in the home. If homeowners have difficulty with any of these steps, a professional can be hired to replace the glass.

Factors Affecting Price of Replacement

The exact cost of window glass replacement can vary based on dozens of different factors. Replacing a standard single pane of glass can be as cheap as buying the pane of glass. However, replacing all the window glass in the entire home and upgrading to a more energy-efficient version as well as hiring professionals to handle the job will be a lot more expensive. The size of the glass being replaced will obviously play a role in the total price, with the larger panes being more expensive. Custom glass will also be substantially more expensive. The type of glass is also important; designer windows, low-E glass windows or any other upgrades may raise the final cost of replacement. Finally, it is important to note that a damaged frame that needs to be repaired or replaced will bring additional costs.

only one company was given and I know there a several others I wanted to compare with.  The cost range is very helpful and will determine when we can have the work done.  Since these windows have aluminum frames it is best for us to obtain professional services.
