Common Crawl Space Problems

Sagging or shifting crawl space beams and posts can lead to a range of problems, including:

  • Basement walls bending or leaning.
  • Uneven or sloping floors.
  • Gaps between walls, floors, and ceilings.
  • The occurrence of mold and mildew often requires comprehensive mold removal services.
  • Cracks, holes, and spaces in drywall.
  • Bowed or tilted walls.
  • Basement moisture issues.

Poor foundation soils and improper pier installation are common culprits behind settling crawl space columns and support beams. Inadequate soil compaction and moisture can prevent the foundation from settling over time. Moreover, incorrect spacing during beam and crawl space jack post installation can lead to sagging. Moisture can also contribute to settling by decaying wooden beams and support posts.

Do you need crawl space repairs?

If you’re planning to sell your house, repairing your crawl space and passing an inspection is essential. This often involves addressing foundation and basement cracks to meet specific state requirements. Delaying inspection and repairs can lead to worsening damage, including water intrusion, wildlife intrusion, and pest infestations.

Understanding Crawl Space Supports and Floor Joists

Crawl space floor jacks are crucial in supporting the structure of your basement or crawl space. They provide support for flooring, furniture, and interior fixtures. Floor joists and horizontal frames used in new homes work with the subfloor to provide stability. These joists span between load-bearing walls or beams and must be parallel and evenly spaced.

How can we help?

Our experts conduct thorough investigations to identify crawl space support issues and recommend appropriate solutions, including:

Transfer of Weight on Stable Loads

If excessive weight is causing floor joists to sag, our crawl space support system can redistribute the weight to more stable areas, preventing further damage.

Support for Extremely Heavy Loads

Our crawl space support system is certified to industry standards and can handle substantial weight, restoring your crawl space to its original capacity.

Return Floors to Their Original Position Using Lifts

Our crawl space support jacks can adjust to various heights and lift significant weight, allowing us to restore your floors to their original position, effectively eliminating the issue..

Trust Groundworks to provide the expertise and technology needed to address crawl space support concerns and safeguard the structural integrity of your home.

I received a few quotes to get the walls in my home filled in with blown in insulation. Zavza Seal was affordable and they did an excellent job.

They were very concerned with cleaning up, which I appreciated. I felt the difference in my home immediately. No more freezing cold walls. I recommend them, hands down.

Efficient, courteous and responsible workers. The job was quoted as being completed in 2 days but more work was required and they returned on the 3rd day and completed the job without additional charges. They reinsulated my crawlspace (not an easy job). I recommend Zavza Seal without reservation.

Couldn’t be more satisfied with the job Zavza Seal did. Brendan and Jake were accommodating, fair and extremely knowledgeable. Their team worked incredibly hard that day under difficult conditions and did a great job. I manage a multi-unit HOA and we will definitely be using them again.
