Common Window Issues in Brentwood Homes
Brentwood's climate, with its warm summers and mild, wet winters, can take a toll on windows over time. Understanding the specific problem is the first step toward an effective and cost-efficient fix. The most frequent issues homeowners face include drafts, broken glass, foggy insulated units, and windows that are stuck or difficult to operate 1 2.
Drafts and Air Leaks
Feeling a breeze near a closed window is a clear sign of an air leak. This common problem is often caused by worn-out weatherstripping or cracked and shrunken caulking around the window frame. Not only do drafts make rooms uncomfortable, but they also force your HVAC system to work harder, leading to higher energy bills. The fix typically involves re-caulking the exterior frame and replacing the weather-stripping, which can often be completed in just a few hours 3.
Broken or Cracked Glass
Whether from an accident, impact, or stress, a broken window pane compromises your home's security, insulation, and appearance. A cracked single pane of glass is a straightforward fix for a professional, who can replace just the glass without disturbing the entire window frame. For more complex units like double-pane windows, the repair might involve replacing the sealed glass unit to maintain energy efficiency 4.
Foggy or Condensation Between Panes
When you see persistent fog or condensation trapped between the layers of glass in a double-pane window, it indicates a failed seal. The insulating gas has escaped, and moisture has infiltrated the insulated glass unit (IGU). Unfortunately, cleaning the glass won't help; the entire sealed unit must be replaced to restore the window's thermal performance and clarity. This is a specialized repair that local glass experts commonly handle 5.
Sticking Windows and Hardware Problems
Windows that are painted shut, warped, or difficult to open and close are a nuisance and a potential safety hazard. This can result from paint buildup, humidity-swollen wood frames, or failing hardware like balances, locks, and tracks. Repairs can range from simple cleaning and lubrication to adjusting mechanisms or replacing broken hardware components 2.
Understanding Repair Costs and Timelines
The cost to fix a window in Brentwood can vary significantly based on the issue, the window type, and the materials needed. Here's a general breakdown of what you might expect for common repairs 5:
- Drafts and Air Leaks: Sealing leaks with new caulk and weatherstripping is often one of the most affordable fixes, typically ranging from $100 to $600. This is usually a quick job that can be completed in a matter of hours.
- Broken Glass Pane Replacement: Replacing a single pane of glass can start around $75, but costs can rise to $2,000 or more for large, custom, or specialty glass (like tempered or decorative). The timeline often depends on glass availability, usually taking 1-2 days.
- Foggy Window (IGU Replacement): To clear the fog by replacing a failed insulated glass unit, homeowners can expect to pay between $100 and $550 or more per window. Since the new IGU must be ordered to size, this repair may take 1-3 days.
- Sticking Windows & Hardware: Fixing operational issues by adjusting or replacing hardware like locks, hinges, or balances can cost between $25 and $500. These repairs are generally completed within 1-2 days.
- Rotted Window Frames: This is a more serious issue. Repairing rotted wood in a window frame can cost between $250 and $800. If the rot is extensive and compromises the window's structure, a full window replacement may be the more prudent and cost-effective long-term solution 6.

When to Repair vs. Replace Your Window
Making the right choice between a window repair and a full window installation is key to managing your home maintenance budget. A good rule of thumb is that repair is usually the best path when the problem is isolated-like a single broken pane, a minor seal failure, or a sticky sash-and the main window frame is still structurally sound.
However, replacement becomes the smarter investment in certain scenarios. If your windows are very old, have widespread rot in the frame, are extremely inefficient (leading to consistently high energy bills), or if you have multiple issues across several windows, investing in new, energy-efficient models may offer better value, comfort, and return on investment over time 6. A local expert can provide the best assessment for your specific situation.

Maintaining Your Windows After a Repair
Once your windows are fixed, a little maintenance can go a long way in preventing future issues and extending their life. Periodically inspect the caulking and weatherstripping for cracks or gaps, especially before the rainy season. Clean window tracks and lubricate moving parts with a silicone-based spray to ensure smooth operation. Avoid painting your window sashes shut, and be gentle with locks and handles. Addressing small problems promptly can prevent them from turning into costly repairs down the line.
