Basement Repair Services in Ottawa

Protect Your Home from the Ground Up

A solid, dry, and healthy basement is the foundation of a safe home. Unfortunately, many Ottawa homeowners face recurring issues with their basements—from water seepage and musty odors to major structural concerns like shifting or cracking foundation walls. At L J Masonry & Construction, we understand the unique challenges posed by Ottawa’s climate and soil conditions, and we offer customized, long-lasting basement repair solutions that protect your home’s value and your family’s safety.

Our team of experienced professionals is dedicated to helping Ottawa residents repair, waterproof, and reinforce their basements with minimal disruption and maximum peace of mind. Whether you’re dealing with minor moisture issues or serious foundation damage, we’re here to help—quickly, professionally, and affordably.

Why Basement Problems Are So Common in Ottawa

Ottawa’s extreme seasonal weather plays a significant role in basement and foundation damage:

  • Freeze-thaw cycles cause the soil to expand and contract, placing pressure on basement walls.
  • Clay-rich soil retains water and swells, increasing hydrostatic pressure on foundations.
  • Heavy spring melts and summer storms often overwhelm outdated drainage systems.
  • Older homes may lack proper waterproofing or have aging foundations prone to cracking.

These conditions can lead to cracks in your foundation, persistent leaks, flooding, and even structural instability if left unaddressed.

Complete Basement Repair Services We Offer

1. Foundation Crack Repair

We repair vertical, diagonal, and horizontal cracks using advanced injection techniques:

  • Epoxy injection for structural cracks that need strong bonding.
  • Polyurethane injection for flexible, waterproof sealing of leaking cracks.
  • Reinforcement options available for large or shifting cracks.

Cracks may look harmless but can lead to serious water damage or structural failure if ignored.

2. Interior and Exterior Waterproofing

Waterproofing is your first line of defense against leaks and flooding:

  • Exterior waterproofing includes excavating around the foundation, applying waterproof membranes, and installing new weeping tiles.
  • Interior waterproofing includes vapor barriers, sump pits, interior drainage systems, and water-resistant wall coatings.

We assess your home’s specific needs and recommend the most cost-effective solution.

3. Sump Pump Installation & Repair

A properly working sump pump is critical in Ottawa homes:

  • New sump pump installation with battery backup options.
  • Sump pump pit excavation and setup.
  • Maintenance and replacement of existing units.

We also test systems to ensure they’re ready for Ottawa’s rainy season and spring thaw.

4. Weeping Tile Installation and Replacement

Weeping tiles manage groundwater around your foundation:

  • Replacement of clogged or collapsed weeping tiles.
  • New installations tied into sump pump systems.
  • Surface drainage solutions to direct water away from your home.

This is essential for long-term moisture control and foundation health.

5. Basement Wall Reinforcement

When walls bow or bulge due to external pressure, we offer:

  • Carbon fiber straps – sleek, non-intrusive support for basement walls.
  • Steel I-beam bracing – heavy-duty reinforcements for severe movement.
  • Wall anchors – installed underground to pull and stabilize shifting walls.

Ignoring structural movement can result in costly foundation failure and safety hazards.

6. Basement Leak Detection & Moisture Control

Sometimes the source of water is not obvious. We provide:

  • Advanced leak detection technology including moisture meters and thermal cameras.
  • Identification of hidden leaks behind finished walls or flooring.
  • Solutions for high humidity, condensation, and damp odors.

Proper diagnosis is key to an effective repair.

Signs You Need Basement Repair

Watch for these early warning signs:

  • Cracks in basement walls or floors
  • Musty odors or visible mold growth
  • Standing water or wet spots after rain
  • Warped or discolored drywall or flooring
  • Difficulty opening windows/doors above the basement
  • Bowing or tilting basement walls

If you notice any of these signs, don’t wait. Delaying basement repairs can lead to more expensive structural damage and health issues from mold and moisture.
