Retaining Wall Repair

Not every damaged retaining wall needs to be replaced. In many cases, localized repairs can extend the life of the wall and address problems before they become more serious.

Common issues we see include:

  • Leaning or bowing
  • Cracked masonry or concrete
  • Loose or deteriorating mortar
  • Sections beginning to separate
  • Water buildup behind the wall
  • Settlement or shifting
  • Damaged or missing stones or blocks

These problems can develop from drainage issues, soil pressure, settlement, weather exposure, or general deterioration over time.

A&A Masonry can assess the condition of your retaining wall and determine whether repair, partial rebuilding, or full replacement is the most appropriate solution.

Retaining Wall Replacement and Rebuilding

Some retaining walls are too damaged for a simple repair.

If a wall has significant movement, widespread cracking, drainage failure, or deterioration throughout the structure, rebuilding may be the better long-term solution.

A retaining wall rebuild may involve:

  • Removing damaged sections or the existing wall
  • Correcting base or drainage issues
  • Preparing a stable foundation
  • Rebuilding with appropriate materials
  • Restoring the surrounding area

A&A Masonry can assess the condition of the wall and recommend whether a repair, partial rebuild, or full replacement makes the most sense.

Types of Retaining Walls

The right retaining wall depends on the property, the grade, the amount of soil it needs to retain, and the look you want to achieve.

A&A Masonry works with a range of retaining wall materials and systems, including:

  • Concrete block retaining walls

  • Natural stone retaining walls

  • Masonry retaining walls

  • Interlocking retaining wall systems

Each option has different advantages in terms of appearance, durability, installation, and cost.

Retaining Wall Cost in Toronto

The cost of a retaining wall can vary significantly depending on the size of the project, the materials used, and the conditions on site.

Factors that can affect pricing include:

  • Wall length and height
  • Material selection
  • Site access
  • Excavation requirements
  • Removal of an existing wall
  • Base preparation
  • Drainage requirements
  • Soil conditions
  • Overall project complexity

Because every property is different, the best way to determine cost is with an on-site assessment.

Our Retaining Wall Process

Every retaining wall project starts with understanding the property and what the wall needs to accomplish.

Our process typically includes:

  1. Site Assessment
    We review the existing wall or proposed location, including grade, access, visible damage, and surrounding conditions.

    We determine whether repair, partial rebuilding, or new construction is the best fit.
  3. Planning and Preparation
    Materials, drainage, base preparation, and site requirements are addressed before work begins.
  4. Construction or Repair
    The retaining wall is repaired or built according to the needs of the project.
  5. Final Review
    We review the completed work and surrounding area before wrapping up the project.

Why Proper Drainage Matters

Drainage plays a major role in how well a retaining wall performs over time.

When water builds up behind a wall, it increases pressure on the structure and can contribute to cracking, shifting, bowing, or other damage.

That’s why drainage should be considered as part of both retaining wall construction and repair, not treated as an afterthought.

A&A Masonry looks at the condition of the wall, surrounding grade, and visible drainage issues when assessing the best approach for the project.

Retaining Wall FAQs

Can a leaning retaining wall be repaired?

Sometimes. It depends on how much the wall has moved and what is causing the problem. Minor issues may be repairable, while significant movement can require partial rebuilding or full replacement.

What causes retaining walls to fail?

Common causes include poor drainage, soil pressure, settlement, deterioration, and problems with the original construction.

Should I repair or replace my retaining wall?

If the damage is localized, repair may be enough. If the wall has widespread cracking, major movement, or structural deterioration, rebuilding may be the better long-term option.

Does a retaining wall need drainage?

In many cases, yes. Water buildup behind a retaining wall can increase pressure on the structure and contribute to cracking, shifting, or bowing.

What is the best material for a retaining wall?

The best material depends on the property, wall height, site conditions, budget, and desired appearance. Concrete block, natural stone, masonry, and interlocking systems can all be suitable depending on the project.

How much does retaining wall repair cost in Toronto?

The cost depends on the extent of the damage, materials involved, site access, drainage issues, and whether the wall needs localized repair or partial rebuilding. An on-site assessment is the best way to determine pricing.

Client Testimonials

We had a front retaining wall, steps and walkway replaced by A&A. The crew was fabulous in all ways. Polite, friendly, helpful, tidy and creative - a pleasure to work with.

They delivered a product that was modified on the fly to accommodate leveling needs and aesthetics, and even switched out some capping that wasn't the "right" color when seeing it with the other products. They were also very careful around the existing garden and saved most of the plants that might have been dug up when rebuilding. The result was excellent - we would use this company again.

General Repair To Brickwork, Retaining Wall, Foundation.
We recently purchased our home, and there were a number of items in our home inspection report for which we were in need of a masonry contractor. We are very happy that we chose A&A Masonry. Greg, who came out to provide the estimate, was very friendly and helpful.

Dwight, who ultimately came out and performed the work on behalf of A&A was excellent. He was very courteous, professional, and careful with his work. We are pleased with the quality of the workmanship but also with the fac that Dwight completed one item on our list that he was not anticipating. That’s great service. Very happy with Dwight in particular, but A&A generally, and we have no reservations in recommending them.
