Window Frame Repair Cost

The cost of hiring a professional to repair a window frame (including materials) usually ranges from $180 to $593 and averages $365. However, window frame repairs differ in complexity and scale, so costs also vary significantly. Small repairs cost as little as $50, while more extensive work costs as much as $1,000.

Factors affecting the overall cost include the nature of the repair, the size of the window, the type of window frame, the time it takes to complete the work, your geographical location and whether you employ a professional or do the work yourself. If you do the work, then costs are limited to your time and any materials you need to rent or purchase.

In some cases, it's not possible to repair a window frame, or you may decide to take the opportunity to upgrade all of your windows. The cost of installing new windows ranges from $2,608 to $7,389 and averages $4,982.

Common Window Frame Issues

Common Window Frame Issues

Common problems for window frames vary based on the type of material; however, all windows have the potential to develop faults. Common issues include:

  • Broken hardware
  • Rotting wood
  • Cracks or holes in the frame
  • Drafts
  • Foggy glass (relating to broken seals)
  • Broken shutters

What Causes Window Frame Repairs?

The most common damage to window frames relates to general wear over time. Exposure to the elements causes paint to flake, and wood starts to rot in the damp. Changes in temperature cause frames to expand or contract, weakening nails and sealant. Hinges rust, and dirt gets into the mechanisms, making them difficult to operate. Damage may also occur as the result of vandalism, an accident, or even improperly fitted window treatments.

What Causes Window Frame Repairs

Window Frame Repair By Window Type

The type of window frame is the best indicator of potential problems. For example, wooden frames require regular treatment to avoid rotting, while aluminum frames don't rot at all but may need re-glazing occasionally. Sometimes, you may need to replace the glass. The cost of replacing glass varies; for example, tinted windows are more expensive to replace.

Wooden Frames

Regularly painting or staining wooden frames helps to preserve them and costs as little as $20 for a can of paint. If wooden frames are poorly maintained, or exposed to extreme weather conditions, they may start to rot or split. Professional window fitters charge from $180 to $380 to patch wooden frames. If frames are completely rotten, then it costs around $700 to remove and rebuild them, and it may be more cost-effective to purchase a new window instead.

Be aware that wooden frames installed prior to 1978 may have a coating of lead paint, which is hazardous to your health. For safety reasons, hire a professional window fitter to work on older windows.

Vinyl Frames

Vinyl frames don't require maintenance other than regular cleaning, making them a desirable alternative to wooden frames. However, expansion and contraction through changes in temperature may cause them to crack. Window fitters charge approximately $600 for the labor and materials to patch vinyl frames with a fiberglass gel. Expansion may also break the sealant around the windows, eventually causing the glass to fog up inside. Replacing the sealant is quick and prevents further damage to the glass.

Aluminum Frames

Aluminum window frames don't require maintenance, and they are resistant to the elements. One of the common issues with this type of frame is broken glazing caused by the metal expanding or twisting. The glazing is the hard putty that creates weatherproof seals on the exterior of the frame. A professional fitter can re-glaze a window in two hours and charges approximately $480.

Broken Hardware

Broken hardware is a fault common to all types of windows. The accumulation of dirt in the hardware's mechanisms may cause them to seize up or break, or they may just become difficult to operate. Employing a home services contractor to replace the hardware costs $50 to $270, depending on how many windows are affected and the quality of the new fittings you select.

Window Frame Repair By Window Type

DIY Or Hire A Pro?

Completing window frame repairs yourself may seem like a cost-effective way to resolve the issue, but it's not always a wise option. Your windows provide security and insulation for your home, so proper installation and maintenance is essential. Poorly fitted windows may be easier to access from the outside or may let warm air escape, resulting in increased energy bills. You may wish to tackle minor maintenance, such as applying new sealant in gaps or repainting wooden frames, but it's usually a better option to employ a professional contractor. Professionals have all the correct tools and skills to repair the frame efficiently.

How To Repair Window Frames

One of the most common types of window frame repair involves replacing rotted wooden sills. This task requires some specialty tools, such as an oscillating saw, circular saw, flat bar and caulk gun. The process is relatively straightforward but requires care and skill to avoid damaging the existing window fittings and to cut a new sill accurately.

  1. Cut the nails securing the sill to the stool.
  2. Cut beneath the sill, and then remove the center section.
  3. Remove the center section of the sill, using a flat bar if necessary.
  4. Break off the sides of the sill using a hammer and chisel.
  5. Remove any nails.
  6. Measure up for the new sill.
  7. Cut, shape and sand the new sill.
  8. Paint the sill with a coat of water-based primer.
  9. Line the recess with caulk, and use expanding foam under the stool for insulation.
  10. Push new sill into position before the foam hardens and expands.
  11. Nail the stool to the new sill.
  12. Seal around the frame with more caulk for waterproofing.
