"Crawlspace was done well and when I found an issue they came back and fixed it right away. Price was in the ball park with other companies. However, we had an exterior foundation leak repaired as well, and they installed a mesh to prevent water from leaking in. 8 months later when water is now leaking in and around their "fix" they won't repair under warranty because "weather conditions are beyond our control". DO NOT USE THEM FOR ANY OUTDOOR SERVICES."

Masonry FAQs, answered by experts

When planning masonry work, you have several eco-friendly options in Ottawa. Consider using reclaimed brick to match historic streetscapes while reducing environmental impact. For older homes, repointing with breathable lime-based mortar prevents moisture damage. Illinois energy codes also mandate continuous insulation for new above-grade masonry walls. Insulated concrete masonry units meet these strict thermal requirements and help reduce your heating and cooling loads.

Helpful?

Always verify that your professional has experience with the historic brick common throughout IL. Older brick requires softer, lime-based mortar to prevent cracking. Ask how the contractor handles cold-weather masonry work, as improper temperature management leads to rapid failure. Request local references to inspect projects that have survived multiple freeze-thaw cycles. Finally, confirm the contractor will secure all required building permits before starting.

Helpful?

The local market features several distinct professionals for masonry work. General masonry contractors handle foundations, walls, and repointing. For chimney repairs, hire a certified chimney specialist. Concrete contractors manage flatwork and block foundations. If you own a historic property in Ottawa, seek a restoration specialist experienced in preservation standards. Finally, landscape contractors build decorative exterior features like retaining walls and natural stone patios.

Helpful?

Start by inspecting your mortar joints. Ottawa experiences severe freeze-thaw cycles, making repointing an urgent priority for preventing structural damage. Next, schedule a chimney inspection to check for cracked clay-flue tiles or improper capping. You should also assess your foundation for efflorescence and mortar failure. Finally, inspect any exposed foundation walls for deteriorating parging, as this layer protects your home from accelerated water damage.

Helpful?

During masonry work, professionals uncover hidden water damage like rotted framing or failed flashing behind the brick. In older Ottawa homes, mortar deterioration extends much deeper than the surface. You must also account for brick matching challenges, as historic sizes and colors require specialty sourcing. Rusted steel lintels above windows require complete replacement and temporary shoring, adding extensive labor and materials to your project.
