- Increases energy savings by 40% to 50%.
- Reflects heat while letting in natural light and reduces UV rays by 70%.
- Reduces condensation.
- May have either soft or hard coats.

Home Window & Door Glass Repair Cost Factors
The cost of replacing window and door glass mainly depends on the opening size, type of glass, location, accessibility, and job complexity. The complete list of factors include:
- Size of the pane (standard vs. custom)
- Single, double or triple pane
- Glass type (tempered, low-E, laminated)
- Labor and glazier prices (heavy glass requires more people to install)
- Window frame material
- Window accessibility (ladder or scaffolding may be necessary)
- Window location (basements, bathroom, bedroom, etc.)
- Glass only vs. complete window replacement
- Frame and other repairs
Labor & Glazier Prices
Labor costs $100 to $225 on average to replace window glass. Glaziers or glass specialists charge a call-out fee of $100 to $150 for the first hour, plus $35 to $75 per hour afterward. Most glaziers offer free estimates and serve a 20 to 50-mile radius.
The average time it takes to replace window glass is 60 to 90 minutes for removing the old glass, cleaning the area, and installing the new glass.
Emergency Window Glass Repair
Emergency window glass replacement costs $100 to $175 extra for after-hours house calls. Same-day glass replacements are available for standard glass types. For custom glass panels that may take 1 to 2 days ship, contractors board up any broken windows with wood.
Window Frame Repairs
Window frame repair costs $150 to $600 on average, depending on the condition, material, and size of damage. Window frames need to be in excellent condition to hold the glass in place and properly insulate. If the window frame and glass has significant damage, a full window replacement may be cheaper.
Reglazing windows costs $100 to $300 per window or $3 to $10 per linear foot to remove old framing putty and apply new glazing. Window-sealing putty often cracks when exposed to the elements. Reglazing improves insulation, leak prevention, and window strength.
Home window tinting costs $4 to $12 per square foot or $40 to $100 per window on average, including the film materials and installation. Tinting windows lowers energy bills, increases privacy, reduces glare, prevents windows from shattering, and reduces UV exposure.
Estimating Glass Replacement Costs
Homeowners with DIY construction experience can replace single pane glass in a small bedroom or bathroom window themselves. Experienced professionals should replace double-pane or larger windows to prevent poor sealing, drafts and gaps, and glass cracks.
How To Measure Glass For Window Replacement
Accurately measuring for replacement glass is essential to buy glass cut to size. Using a tape measure, record the following dimensions:
- Width and height of the original glass pane.
- Thickness of the old glass.
- Next, round the width and length to the nearest 1/16 inch.
- Subtract 1/8 inch from both measurements to account for contraction and expansion of the frame.
- Use these measurements to buy glass cut to size at a hardware store.
Tools and Supplies
The tools and supplies required for DIY window pane replacement cost $35 to $85, not including the glass.
Tools and supplies needed:
- Razorblade scraper
- Work gloves
- Putty / Glazing material
- Paint scraper or blade
- Glazier points (optional)
How To Replace Window Glass
Homeowners with construction experience can learn to replace lightweight window glass with the right tools and if the frame doesn’t need repairs.
Follow these steps for replacing single pane glass:
- Remove the old window pane and broken glass with gloves.
- Clean all old caulk, putty, and old paint buildup from inside the frame.
- Fit the replacement glass into the frame and secure it with glazing points, double-sided tape, or light caulking.
- Apply the putty or caulk in the edges of the frame evenly.
- After drying, paint the putty, or cover it with trim.
Always hire a professional for double pane windows to prevent insulation problems, window leaks, cracks, and other improper installation issues.
Reasons To Replace A Glass Window Pane
Aside from repairing broken window panes, there are several reasons to replace the glass in windows.
When To Upgrade Window Panes
- Increase energy efficiency
- Increase home value and curb appeal
- Decrease noise pollution
- Fix drafting, leaking, or condensation
- Protect against UV rays
- Old age (20+ years) or out of date
- Improper locking or closing
- Poorly insulating single pane glass
- Glass scratches, screen-burn etching, cracks
- Security upgrades for more durable tempered glass
While a glass replacement is cheaper, buying new windows might be best for extensive damage, or an old bay or bow window that’s often more expensive to repair.
Upgrading to Energy Efficient Windows
Updating single pane glass to ENERGY STAR rated dual pane windows saves $100 to $600 in utilities annually. About 25% to 30% of energy loss happens through thin glass panes and damaged or low-quality window frames. Experts recommend argon-filled insulated glass with a reflective Low-E coating.
For even greater energy efficiency, consider replacing aluminum window frames with wood, wood-clad, or vinyl (UPVC) sashes. Triple pane glass insulates the best in extreme climates. Alternatively, adding storm windows and a solar film dramatically increases energy efficiency.
Frequently Asked Questions
Can You Replace One Pane on a Double Pane Window?
Both panes in a double pane window must be replaced to maintain an airtight seal for energy efficiency. Damaged double pane windows often need a full-window replacement instead of the glass only. New dual-pane windows are customized to fit and sealed with argon gas between the panes for insulation.
Is It Cheaper To Replace Glass or Whole Window?
A full-frame window replacement costs 50 to 100 percent more than only replacing the glass. Glass-only replacement is recommended when the window frames are in good shape and a glass pane cracks, the sash is broken, or the window is foggy with condensation between the panes.
|Replace Glass||Replace Whole Window|
Can A Cracked Window Be Fixed?
Replacing the glass is the only way to fix a cracked home window completely. While most cracks won’t immediately spread, quickly replacing the broken window glass prevents injuries and maintains energy efficiency.
To temporarily seal cracked windows:
- Small Cracks – Clean the crack and apply superglue or shellac inside.
- Large Cracks – Cover both sides of the crack with masking tape.
- Severe Damage – Cover with a piece of plywood for extra security.
Hiring A Window Glass Repair Company
Before hiring a glazier or window repair specialist, plan accordingly, get multiple quotes, and know what questions to ask. For smaller window glass repairs, consider hiring a handyman.
- Check the window manufacturer’s warranty and homeowner’s insurance for glass-replacement coverage.
- Get at least three quotes to compare prices. You'll need the window size, type, and the number of panes to get an accurate estimate.
- Ask for recommendations from family, friends, and neighbors.
- Read reviews and check out their previous work on HomeGuide, Google, and the Better Business Bureau (BBB).
- Select companies that are insured, bonded, and have been in business for longer than five years.
- Ensure they completed at least 3 to 12 months of apprenticeship or obtained their glazing contractors license. In some states, only contractors' require licenses, not the glaziers who work for them.
- Avoid selecting the lowest quote as quality may suffer.
- Ask for a full itemized contract in writing in case of a dispute.
- Ask for a clear written warranty on the glass and labor.
- Avoid making large payments upfront and come up with a payment schedule for work completed.
