Foundation Masonry Repair

Where the building meets the ground, water and movement do the most damage.

Overview

Foundation masonry — brick or concrete block below and at grade — sits in the harshest spot on the building: in contact with soil moisture, hit by runoff, and subject to settlement and frost movement. Deteriorated mortar, cracked or spalling block, bowing, and step cracks at the foundation level let water into basements and crawlspaces and signal movement that needs attention before it spreads upward.

We repair foundation masonry: repointing deteriorated joints, replacing spalled brick and cracked block, addressing the water and drainage causing the damage, and stabilizing where movement is active. Structural movement beyond masonry repair is identified honestly and coordinated with the right specialists.

Scope of Work

  • Foundation repointing and joint repair
  • Cracked and spalled block replacement
  • Below-grade brick repair
  • Parge coat repair and application
  • Water-entry and drainage correction
  • Crack assessment and stabilization

Warning Signs

When to Call Us

01

Deteriorated Mortar at Grade

Mortar joints at and just below grade take constant moisture and freeze-thaw. Recessed, soft, or missing mortar here lets water directly into the foundation wall.

02

Cracked or Spalling Block

Cracked concrete block or spalling brick at the foundation indicates moisture damage or movement. Left open, these become direct water paths into the basement.

03

Step Cracks in the Foundation

Diagonal stair-step cracks following the joints often indicate differential settlement. The crack pattern tells us where the movement is originating and whether it's ongoing.

04

Basement Moisture or Efflorescence

Damp interior foundation walls, white salt deposits, or musty smells point to water moving through the foundation masonry — usually from failed joints or grading and drainage issues outside.

Materials We Use

  • Type S mortar for below-grade and structural joints
  • Replacement concrete block and brick
  • Parge and waterproof coatings
  • Hydraulic cement for active seepage points

What Affects the Price

  • Extent of deteriorated masonry
  • Whether drainage/grading correction is needed
  • Access and excavation requirements
  • Active movement vs. static damage

Every building is different. We provide free on-site estimates so you get a real number for your property — call (708) 288-1696.

Making the Right Call

Masonry repair vs. structural underpinning

Most foundation masonry problems are repointing, unit replacement, and water correction. When cracks indicate active settlement, that's a structural matter beyond masonry — we identify it honestly instead of sealing over a moving wall.

FAQ

Common Questions

It depends on the type. A crack through the mortar joint only is often manageable with repointing. Wide, stair-step, or actively widening cracks can indicate settlement and need assessment before repair. We give an honest read on-site about what's cosmetic and what's structural.

Often, yes — by repointing failed joints, replacing damaged masonry, and correcting the grading or drainage feeding water to the wall. Where the problem is hydrostatic pressure or a failing drain tile, we'll tell you and coordinate the right approach rather than just sealing over it.

We handle foundation masonry repair — repointing, brick and block replacement, and stabilization. When movement points to a structural issue beyond masonry (piering, underpinning), we identify it honestly and coordinate with the appropriate specialist.

Soil moisture, poor drainage, and Chicago's freeze-thaw cycle. Water saturates the masonry at grade, freezes, and breaks it down; settlement and frost heave add movement that cracks joints and units.
