Cracks & Holes in Windows

Potential Problems

• Small cracks or holes in your windows can lead to greater disrepair and damage as your home’s interior is exposed to the elements. Compromised windows are in danger of breaking, which means your family and pets may be cut by glass shards. The openings waste energy, allowing your heated or cooled air to escape. Rodents and insects may enter your home through breaks. Broken windows can also compromise your home’s security.

Maintenance

• Check for broken glass at least once each year. The spring and fall are the best times to inspect your windows. Assess the condition of your window putty in the spring, and repair or replace hardware to prevent breaks from windows that stick in the fall. Check for moisture problems; rot can trigger sagging that may cause poor function and fit, which may lead to breakage. Remove and replace putty that is chipped, missing or damaged. Many glass companies offer home installation services that will repair or replace broken windows. Salvage companies and artisan glass shops carry older glass if you need to replace glass in an historic home.

Temporary Solutions

• The ServiceMagic website suggests methods for mitigating damage and affecting short-term repairs, including placing duct tape over cracked glass to prevent further breakage, caulking around cracks near the sash or frame, and using plastic kits to seal your windows against openings during colder months.

Repair vs Replacement

• If repairs are extensive and expensive, or the potential energy savings will be enough to justify replacement, you may opt to upgrade to newer, more energy-efficient windows; however, in many cases, you can restore the proper function of older windows. Properly weatherstripped and accompanied by storm windows in good condition, old windows can perform as well as double-pane replacement windows, sparing you the cost and inconvenience of replacement.
