Most sliding doors should be repaired rather than replaced, as repairs are typically 60-80% less expensive than replacement. However, replacement becomes the better option when the door frame is severely damaged, the door is over 20 years old, or repair costs exceed 50% of replacement value.
The decision between repair and replacement depends on several key factors that Chicago homeowners should carefully evaluate before making this important investment.
Cost Comparison: Repair vs. Replacement
Typical sliding door repairs range from $150 to $400, covering common issues like roller replacement, track cleaning, or weatherstripping renewal. Full door replacement, on the other hand, usually costs between $1,200 and $3,500 including installation.
When considering whether it’s better to repair or replace a sliding door, calculate the total repair costs against replacement value. If repairs would cost more than half the price of a new door, replacement often provides better long-term value.
Age and Condition Factors
Doors manufactured before 2000 often lack modern energy efficiency features and may use outdated materials that are difficult to match during repairs. These older units frequently benefit more from replacement than attempting multiple repairs.
Newer doors with isolated problems like sticky operation or minor seal issues typically respond well to targeted repairs. Professional door specialists can assess whether your door’s overall condition justifies repair investment.
When Replacement Is the Clear Winner
Certain situations make replacement the obvious choice regardless of initial cost concerns. Cracked or warped door frames cannot be effectively repaired and compromise your home’s security and energy efficiency.
Similarly, doors with broken glass panels, especially double-pane units with failed seals, often cost nearly as much to repair as replace. Water damage around the door frame also typically requires full replacement to prevent ongoing moisture problems.
Energy Efficiency Considerations
Modern sliding doors offer significantly better insulation and weatherproofing than units installed even 10 years ago. If your current door allows noticeable drafts or shows condensation between glass panes, replacement can reduce heating and cooling costs substantially.
Many homeowners find that energy savings from new doors offset replacement costs within 5-7 years, making replacement financially attractive even when sliding door repair remains technically possible.
