Evaluate the stairs
Review visible cracks, worn surfaces, loose edges, drainage and signs of leakage. Determine whether opening selected areas is needed to understand concealed conditions.

Magnesite & Stair Repair in Los Angeles & Orange County
Cracked steps, loose edges or recurring leaks? We evaluate your existing magnesite stairs and landings, explain what can be repaired, and identify when removal and a new waterproofing assembly are needed.
Experienced waterproofing since 1985
Magnesite stair repair, removal & waterproofing
Cracked magnesite steps, crumbling stair edges, hollow areas and leaking landings can indicate deterioration beneath the surface. We evaluate the existing material, supporting assembly, drainage and wall transitions before recommending localized magnesite repair or broader removal.
Where removal is needed, the exposed plywood, framing or metal can be evaluated before a compatible replacement waterproofing assembly is installed. Concealed repairs are documented and addressed through the agreed scope or a change order. The proposal identifies the replacement materials, finish texture and access arrangements; a magnesite repair does not automatically mean installing new magnesite.
From our project portfolio
Walkways and stairs, treated as a complete assembly
Our featured CIM 1000 walkway and staircase project illustrates the attention given to walking surfaces and adjoining details. Your repair system is selected after evaluating your own stairs and substrate.
View our projectsHow the work is approached
A complete scope—not just a surface coating
Repair the supporting assembly
Remove approved damaged areas and evaluate the exposed substrate. Coordinate necessary structural or metal repairs before waterproofing covers the work.
Waterproof and finish
Install the selected compatible assembly with attention to edges, landings and transitions. Choose a pedestrian finish and allow the required curing time before reopening.
Common applications
Projects we can evaluate
The final recommendation depends on site conditions, access, the existing assembly and what is uncovered during approved preparation or demolition.
- Apartment exterior stairs
- HOA stairways and landings
- Existing magnesite surfaces
- Residential entry stairs
- Stairs adjoining elevated walkways

Magnesite & Stair Repair FAQs
These answers explain the decisions that usually affect scope, scheduling and system selection. The final recommendation is based on the conditions at your property.
Ask about your projectCan you repair existing magnesite instead of replacing everything?+
That depends on the extent of damage, adhesion and the condition of the supporting assembly. We assess whether a localized repair is practical before recommending broader removal. A surface inspection cannot establish every concealed condition.
Will you simply coat over cracked stairs?+
The scope must address the cause and condition of the damage. Loose material, failing edges and damaged substrates need appropriate preparation or repair before a compatible waterproofing system is installed.
Do you install new magnesite on every repair?+
No. We evaluate the existing magnesite and specify a suitable repair or replacement assembly for the substrate and exposure. The proposal identifies the materials to be installed.
Can residents use the stairs while work is underway?+
The affected stairs may need to close during removal, installation and curing. Access arrangements and the work sequence must be coordinated with the owner or manager before starting.
