Common Mistakes to Avoid

1. Ignoring Underlying Issues

Reason: Focusing solely on surface-level problems like a sticking door without addressing the cause (e.g., warped frame, foundation settling) leads to recurring issues.
Solution: Address the root cause of the problem, such as shimming a warped frame or adjusting the foundation, before tackling the symptoms.

2. Using the Wrong Type of Lubricant

Reason: Using petroleum-based lubricants attracts dust and dirt, eventually causing more problems than they solve.
Solution: Use a silicone-based spray lubricant designed for exterior doors to avoid attracting dirt and maintain smooth operation.

FAQs

How much does professional front door repair typically cost?
The cost varies greatly depending on the extent of the damage, the type of door, and the necessary repairs. Minor adjustments might cost a few hundred dollars, while extensive repairs or replacements could reach several thousand. It's best to get multiple quotes from reputable professionals before making a decision.
What should I do if my front door is stuck?
Avoid forcing the door, as this could cause further damage. First, check for obstructions like warped frames or swollen wood.

They have specialized tools and expertise to diagnose and fix the problem safely.
