Magnesite Decking in Los Angeles & Orange County
Skilled magnesite repair and replacement that restores worn, cracked, and failing deck substrates, then seals them with a lasting waterproofing system.
Takes about 30 seconds. No obligation, no pressure.
Bring Failing Magnesite Decks Back to Life
Magnesite shows up on many older Southern California decks and stairs, and over time it cracks, delaminates, and lets water reach the structure underneath. Patching over failing magnesite rarely holds, the underlying problem keeps spreading until the substrate is addressed.
Balcony Works removes and repairs failing magnesite, rebuilds a solid substrate, and applies a modern waterproofing system over it, giving you a durable surface backed by our 8-year warranty on most projects.
Signs Your Magnesite Deck Is Failing

Common Magnesite Decking Questions
Is it better to repair or fully replace a magnesite deck?
It comes down to how far the deterioration has spread. We check the substrate during a free inspection and recommend either targeted repair or full replacement, whichever protects your property better.
How long does a waterproofing job hold up?
A properly installed system typically holds up for years. Most of our projects come with an 8-year workmanship warranty, and regular upkeep can stretch that lifespan even further.
What should I expect to pay for waterproofing in the LA area?
Pricing depends on the size of the surface, its current condition, and which coating system fits the job. After a free on-site inspection we give you a clear, itemized quote, no pressure and no obligation.

Most residential decks, balconies, and stairs wrap up in one to three days depending on prep work and weather. You will get a firm timeline before the crew starts.
