Work Gloves

Work gloves provide protection to your hands when handling broken glass. While many recommend using heavy-duty leather gloves, it can be difficult to work in them due to their stiffness. An alternative is to use abrasion-resistant, and breathable safety gloves.

Putty Knife

A putty knife serves dual purposes when it comes to replacing window panes. Not only does it help you to spread glazing into the cracks between the pane and the window frame, but also helps you install the glazing points which hold the window in place.

Wood Chisel or Razor Scraper

In order to remove larger pieces of glass, you may need to remove old glazing from around the edges of the frame. Although it is possible to cut this glazing using a standard box cutter, the safest solution is to use a razor scraper or a wood chisel.

Paintbrushes play an important role because after you have removed the old pane of glass and window glazing, you will need to re-glaze the new windowpane, and eventually paint the window itself.

Tape Measure

Not all windows are created to specific dimensions. Older windows for example generally tend to have different sized panes that are cut on-site during the actual construction of the home. As a result, you may need to measure the size of the frame in order to purchase another windowpane.

Glass Cutter

A glass cutter is essential if you need to cut glass window panes yourself. These tools are specifically designed to score the face of a pane of glass in such a manner that you can “break” it in order to make a straight cut.

Metal Straightedge

Although many places that sell replacement window glass can also cut the glass, you may be left in a situation where you have no other option but to cut the glass yourself. In order to make a straight cut, you will also need to pick up a metal straightedge as a guide for the cut.

Pencils are great for marking, and although you could use a typical number two household pencil, if you truly want to be a DIY handyman, then you’ll need to keep some carpenter’s pencils lying around just in case.

Rubber Mallet

If you chose to purchase a wood chisel to help remove glazing, then a rubber mallet will come in handy. Traditional steel-headed hammers are not the right tool for smacking the end of a chisel.

How to Buy Replacement Window Glass for Your House

Believe it or not, the actual process of purchasing replacement window glass is fairly easy. In order to get the correct glass, you will need to know a few things about the glass pane that you are replacing. Not only do you need to know what size the piece will need to be, but you will also need to know how thick the glass is. But, knowing the dimensions of the glass that you need is only half the battle.

Tempered Glass

Traditional panes of glass break along a spider crack, leaving large chunks of sharp edges to get caught on. This can lead to a dangerous situation if you live in an area that regularly sees high winds or dangerous storm patterns. In order to prevent the possibility of shards of glass being strewn throughout the house, many homeowners instead ought to use tempered glass which breaks into small beads when shattered.

Laminated Glass

Depending on local building codes, the tempered glass may not be appropriate. Instead, some areas may require that you make use of laminated glass. This type of replacement glass is specially treated with a film which makes it less likely to break or shatter in the event of an impact. This film also prevents the shards of glass from being strewn all over the home if it is broken.

Insulated Windows

If you are working with insulated, energy-efficient windows that have at least two individual panes of glass, then replacing this glass on your own can be an impossible task. Many of these windows are filled with inert gas, like argon, in between the layers of glass.

Where to Purchase Home Replacement Window Glass

Once you have been able to determine what type of glass your window is, all you need to do is to locate a retailer who provides replacement window glass. Although some large box store retailers can provide most types of glass, for specialty glass such as tempered or laminated windows, you may need to go to a specialist.

Below are a few stores that can supply replacement home window glass in the United States. But, before you go out and purchase replacement glass for your window, check to make sure whether your window is still under warranty or not.


Lowe’s hardware is one of the more common big-box stores in the country. Most of these locations not only sell a variety of replacement glass for your DIY project, but they can usually cut the glass for you. All you need to do is to bring a sample, and the dimensions that you need cut.

Home Depot

In the past, Home Depot used to provide glass cutting services at most of their locations, however, in recent years they have stopped offering glass cutting and installation altogether. You will still be able to purchase replacement glass at any Home Depot store, but you will need to cut it yourself.


Menards sells a variety of replacement glass for just about any purpose. Make sure to bring your sample and the dimensions with you, because many locations do offer a glass cutting service. However, some locations may not, depending on whether or not they have an experienced cutter on site.

Ace Hardware

Ace Hardware is the place to go when it comes to not only buying replacement glass but also getting a cut. Although most stores charge a small fee for this cutting service, they are able to cut both replacement glass as well as acrylic or plexiglass sheets.

True Value

Most True Value locations offer glass cutting services in-house. However, since true value is operated as a franchise, not all stores offer the service. It is important to contact your local True Value Hardware to determine whether or not they specifically offer glass cutting services.

Cost of Home Window Glass Replacement

When it comes to a cracked or even broken window, the first thing that any homeowner thinks about is the costs associated with their home glass window replacement. After all, the annual cost of maintaining any home is already more than most homeowners like.

In determining what it would cost to replace a broken window, there are certain things that need to be taken into consideration. The most important of these is what type of window is broken. Energy-efficient windows with multiple panes of glass are more expensive than traditional single pane wooden framed windows. However, the average price of a double-hung window is between $500 and $700. Depending on the manufacturer and materials, this can easily range anywhere from $200-$1200.

But, the cost of the actual window is only part of the equation. Depending on where you live, you may need to pay an installer anywhere between $30 and $50 per hour. Although it will generally take an installer 1 to 2 hours in order to install a replacement window on the ground floor of a home, the upper-level floors can take longer.


Once you have sourced your window repair tools and home window replacement glass, and cleaned up any broken glass, you are ready to move onto replacing the window pane or fixing that crack.
