Our Foundation and Basement Services in Cortland

If you’ve seen flooding in your basement during heavy rains, foundation problems, or crawl space moisture, these could be signs of severe problems. Urgent consultation with a reputable repair company like Perma-Seal is essential. Prolonged issues can lead to other complications such as mold proliferation, structural weaknesses, and permanent foundation damage.

Basement Waterproofing Solutions in Cortland

The basement, whether used to store valuables or as a living room, should always be free from moisture and high humidity. Basement seepage can present themselves in several ways:

  • Foundation wall cracks which occur in block and concrete foundations.

  • Cove joint seepage.

  • Old basement widnows.

Our experienced experts in Cortland employ trusted solutions to tackle these issues. From wall crack repairs to complete basement drainage systems, we guarantee water stays out of your space. Moreover, with our sump pump installations, your basement gets an extra layer of defense against unanticipated basement water leaks.

Professional Foundation Repair Solutions

Your foundation isn’t merely for supporting your home—it’s an integral part of its overall health. Signs of foundational issues encompass:

• Zigzagging cracks on external brickwork.

• Cracks spanning basement walls or the foundation itself.

• Hard to open doors or windows.

• Basement walls that seem to be bowing inward.

These indicators should never be ignored. Our team in Cortland provides a range of services, from foundation pier installation to installing wall anchors for bowed foundation walls, ensuring your foundation remains strong and stable.

Professional Crawl Space Solutions

Homes and businesses in Cortland and the neighboring regions have crawl spaces rather than basements. Traditionally, these spaces were vented to maintain dryness. However, vents can allow moisture to gather, fostering mold growth and affecting air quality. Perma-Seal’s crawl space encapsulation system guarantees your crawl space is sealed and dry, improving your indoor air quality.

Indicators to look out for:

Flooded Crawl Space
Uneven Concrete Sidewalk

Concrete Lifting Services

Uneven or sinking concrete surfaces not only blemish the aesthetic of your property but also pose possible trip hazards. Such anomalies can arise due to different reasons:

  • Erosion of soil from overabundant rainwater or insufficient drainage.
  • Failure to compact, often seen in soil-filled areas after construction.
  • Natural soil settling over time.

In Cortland, our Perma-Seal experts utilize advanced concrete leveling techniques. We adjust uneven slabs, making sure a level and even surface. By choosing concrete leveling rather than replacement, you save time, money, and obtain an instant solution for those precarious uneven paths, patios, or driveways.
