At Ewell Construction, we provide expert leak detection and waterproofing for exterior spaces throughout the South Bay, including Redondo Beach, Torrance, Manhattan Beach, and surrounding communities.​​

Why Do Deck & Balcony Leaks Happen?

Most leaks are caused by:

• Poor or aging waterproofing systems
• Cracked deck coatings or tile grout
• Improper sloping or drainage
• Loose railings or fasteners allowing water intrusion
• Damage from earthquakes, weather, or wear over time
• Rusted or deteriorated flashing

FAQs – Deck, Balcony & Railing Leak Repairs​

Q: How do I know if my deck or balcony is leaking?
A: Signs include water stains on ceilings below, soft or swollen wood, bubbling paint, musty odors, or visible cracks in surfaces.

Q: Can you fix leaks without tearing up the whole deck?
A: Often, yes. We can perform targeted waterproofing or recoat the surface depending on the damage. We'll always give you options.

Q: Do leaking railings need to be replaced?
A: Not always. If water is getting in through fastener points or gaps, we can seal and reinforce those areas. If railings are rotted or unstable, replacement may be best.

A: We service wood decks, concrete balconies, waterproof-tile systems, vinyl decks, and everything in between—residential or commercial.
​
Q: How much does leak repair usually cost?
A: Minor fixes can start around $500, while full waterproofing or rebuilds may range from $3,000–$15,000, depending on size and materials.
