Windows are a really important element in any home, and that’s why they require periodic maintenance. The connection with the outside environment brings a double benefit, which is translated by a beautiful view of the landscape and having the right element to welcome friends and relatives who pass by the house. For some of the damages that can occur in the case of windows, the solution can be reglazing.

How Much Does It Cost to Reglaze Windows?

The cost to reglaze a window will vary, depending on factors such as the size of the glass pane and windows, the total number of windows, and the material used for the frame and window.

Plan on spending anywhere between $300 and $750 for reglazing a traditional window. This price range will include the window repair, the material cost, and the labor cost. It may take fifteen minutes to one hour to reglaze a single pane of glass.

Expect to pay around $1,510 to reglaze a large-size vinyl or wood window. It would cost you anywhere between $650 and $1,220 to replace three panels of a bay window.

For instance, if a section of an average window is cracked or rotted, you will have to pay $200 to $550 to repair it.

Window glazing overview

Years of use, harsh weather conditions, and sometimes lack of maintenance can lead to worn and cracked windows. In order to protect them, regular care is required, regardless of the type of frame from which the windows are built, from vinyl, wood, and aluminum frames to thermal insulation frames, so that they last longer and protect the home.

A window is made of panes of glass, mounted on the window frame. The space between them is filled with glazing putty.

Why it is important to reglaze windows?

It is important to reglaze windows because it brings many benefits such as:

  • Offers protection to the windows after restoration.
  • It will help control the temperature inside the house
  • It keeps the storm windows or wooden windows weathertight.
  • It prevents energy loss, air leaks, and loss of heat.
  • It keeps the window glasses in place and so the windows will need less fixing.
  • The energy of your house will be increased.

Signs you need to reglaze your windows

There are many signs that show you that you have to reglaze the windows immediately. Some of these include:

  • The window edge is not covered properly.
  • Cracked glaze falls off the window glaze.
  • More than ten to fifteen years have passed since the windows have been glazed.
  • Air and heat leakage from the house.
  • The windows must be reglazed after you replaced them.

Cost of sealant or glazing putty

There are three types of putty on the market and the price will be different for each of these. In general, you will need less than a pint of glazing to reglaze a small pane or a single window. Expect to pay around $100 for a 20 oz. container of glazing.

Of course, the costs for a double-pane window will be higher than for a single-pane window. You can find sealants and putty at any hardware store. The window glazing cost will be determined by the size and number of windows.

You will have to buy a larger container if you have large windows and so your costs will increase.

Quality of the Putty Cost Range
Premium Quality $75-$120
Mid-range Level $40-$75
Budget-friendly $15-$40

The cost of glass replacement

Single-pane glass can break very easily but can take any shape. This is why most people choose double glass windows. It meets the standards of modern building codes and is very durable. This can be bought from any hardware store and can be cut in any size and shape you need.

Cost for a window reglazing professional

You will have to pay anywhere between $55 and $160 per window for hiring a professional to come and reglaze your windows. The cost will depend on the labor time, the window’s condition, and the place where you are living.

Usually, it is necessary to be very careful when reglazing or replacing the windows of an old house. It is recommended to hire a professional glazer to replace an old window with a double-paned window or to glaze it.

A step-by-step guide to reglaze windows at home

  1. Investigate the window’s condition

To test if your window has to be reglazed, you can place a knife blade in the cracks and if it fits there then you must reglaze the windows. After that, you have to establish how many windows and glass panes you need to repair.

  1. Remove the damaged glaze

Remove the faulty glaze using a scraper or a razor knife. Take care when you chip off the glaze from the window not to break the glass.

Also, you can use a heat gun to soften the glaze if it is hard to remove. But be careful because it may affect the paint of nearby areas.

  1. Remove the faulty wood and glass

Only the wood and glass will remain in the frame after removing the glaze. If these are damaged you have to remove them.

  1. Replace the wood and glass

Take measurements of the old pieces of wood and glass and purchase the same size from any hardware store.

  1. Reglaze windows

The glazing compound must be kept at room temperature or warm. This way it will be easy to give it any shape.

  1. Paint the glaze

You should leave ten to fifteen days before applying the paint. This step is not mandatory but may increase the lifetime of the glaze.

Things to pay attention to when purchasing glazing putty

You should expect that your new reglazed windows will last ten to twenty years. To make sure this improvement will last as long as possible, you will have to consider some important features when buying glazing putty, such as:


Regardless of what brand you buy, the glazing putty has to be weatherproof. You will just waste your money if this does not survive in any weather conditions.

Drying time

The main feature you should look for is the drying time. You will finish the work and paint the surface faster if it dries quickly. Buy the product that will dry faster than others.


The glazing putty has to remain elastic in the container before it is applied to the window and dried up. Verify it before buying. You should avoid the ones that get hard in the container.


In general, the low-cost putty shrinks after drying up. This will expand the smoothness of the glazed surface and will make the holes visible. Try to avoid this type of product.

Yellowing or marks

There are some glazing putty brands that may leave marks or yellowing on the window after applying and drying. Buy the glazing putty that offers a bright appearance after drying.

What is better? Replacing windows or reglazing windows?

Reglaze a WindowIn general, it is hard for people to decide between replacing or reglazing windows. In the case of reglazing, when the old putty runs out, the windows are filled with new glaze. In most cases, it is an easy job and takes very little labor and time.

When replacing a window, the old one is removed and a new set of wooden windows or metal windows is installed. This process takes more time and labor.

Your decision depends on the window’s condition. If it’s still in good structure and the glass panes are also good looking and only the glaze is affected, then you should choose to reglaze it.

On the other hand, if the window is too old and the glass panes are cracked, you should replace it. In the case of old house windows, it is more beneficial to replace them instead of reglazing.

Tips for saving money

When reglazing a window, there are some routes you can choose in order to save money. These would include:

  • The cost for single glazing will be half the cost of putting double glazing after glass repair.
  • You can reglaze windows on your own. This is a DIY job.
  • Buy an elastic window putty that will last a long period of time.
  • Try to use the remaining putty from any previous work, if it is still in good condition.
  • Use the traditional hard linseed oil putty.
  • The previously used glass can be used again.
  • Replace the old glasses with single-pane glass.


How long does window glazing last?

Window glazing may last 10 to 39 years, depending on the putty type, window materials, putty quality, and others.

How long does it take for the window glaze to dry?

Depending on the type of glaze, it may take 5 to 30 days for the window glaze to dry. For instance, water-based glazing takes 5 to 15 days to dry, while oil-based glazing may take 15 to 30 days to dry.

Is it difficult to reglaze windows?

The difficulty of this job depends on the glass pane condition and window condition. If you only need to place in putty you can try a DIY job, but if you have to replace a damaged frame or wood and remove the window, then you should hire a professional.

Can I reglaze windows without removing them?

Yes, windows can be reglazed without having to remove them. If the wooden frame and glass pane are in good condition, you can reglaze the windows without removing them.
