What Is Masonry Repair?
Masonry repair is the restoration of any brick, block, or stone structure that has sustained damage from water infiltration, settlement, freeze-thaw cycling, or age. This includes foundation walls, retaining walls, steps, window sills, lintels, and decorative masonry elements. Proper masonry repair restores structural integrity and prevents small problems from becoming expensive rebuilds.
Six Signs You Need Masonry Repair

Sign 3

Masonry structures rely on every component working together. When one element fails, it transfers stress to adjacent elements, creating a chain reaction of deterioration.

Our Masonry Repair Process
Structural Assessment
We evaluate the full masonry structure - not just the visible damage. Cracks, movement, water patterns, and load paths are all documented.
Root Cause Identification
We determine why the masonry failed: water, settlement, overloading, frost heave, or material deterioration. Fixing symptoms without addressing causes wastes money.
Repair Plan Development
We create a repair scope that addresses both the visible damage and the underlying cause. You get a written estimate detailing every element.
Material Preparation
Correct mortar type, matching brick or block, proper drainage materials, and waterproofing products are sourced before work begins.
Expert Execution
Our licensed crew performs the repair using ASTM-compliant materials and techniques. Our own crew, no shortcuts.
Final Inspection
Walkthrough of all completed work and documentation of repairs.

Request EstimateTechnical Standards & Mortar Types
Masonry repair requires matching the mortar type to the application. Foundation work demands higher compressive strength than above-grade walls.
| Mortar Type | Compressive Strength | Correct Use | Risk if Misused |
|---|---|---|---|
| Type N | 750 PSI | Above-grade walls, steps, decorative masonry | Not suitable for foundation or retaining wall applications. |
| Type S | 1,800 PSI | Foundations, retaining walls, below-grade, heavy load areas | Standard for structural masonry repair. Good balance of strength and flexibility. |
| Type M | 2,500 PSI | Severe load-bearing, retaining walls under heavy soil pressure | Maximum strength. Limited flexibility. Used only where loads demand it. |
All Delta work follows ASTM C270 Standard Specification for Mortar for Unit Masonry.
Masonry Repair Pricing
Masonry repair scope varies widely. Free on-site assessment determines exact scope and pricing. We never recommend more work than the structure requires.
What Our Customers Say
"Our front steps were separating from the house and sinking. Delta rebuilt them completely - new footing, new treads, new cheek walls. Rock solid and look great."
"Foundation wall was leaking in two places. Delta tuckpointed the interior block, sealed the cracks, and solved a problem we had lived with for years."
"Retaining wall was leaning badly. Two companies said tear it down and pour concrete. Delta rebuilt it in block with proper drainage. Looks better than the original."
