Crawl Space Support Post Installation in Long Island
Stabilizing Posts (Support Jacks) to Stop Floor Sagging in Suffolk & Nassau County
Are the floors above your crawl space starting to sag down or feel bouncy? You are not alone. Faulty floors above the crawl space are common in Long Island homes.
Sagging floors are caused by structural issues under the floor, which means if left ignored, the problem will only grow worse, even becoming unsafe. The sagging floors can also lead to wallboard cracks and out-of-level door frames in your Long Island home.
Why is the Floor Above my Crawl Space Sagging or Bouncy?
Construction defects cause sagging floors – several issues can be the root cause.
Long Spans: In some Long Island homes, the floor joists cover long spans beneath the floor, but the joists need to be thick/strong enough for these spans. If the joists under your crawl space are undersized, they cannot handle the weight of people and furniture on the floors above and begin to sag.
Lack of Mid-span Support. The joists in crawl spaces are supported by foundation walls and often by a central support beam. Unfortunately, some crawl spaces lack this support beam, creating the long-span
Sunken/Damaged Piers. The masonry piers that support the central beam can sometimes sink, and wood support posts can rot or shift. When these piers start to fail, stress is placed on the central beam and, in turn, the floor joists, creating a sagging, bouncy floor. Failing piers are more common in older Long Island homes.
Fixing Sagging, Bouncy Floors
The solution to fixing sagging floors above the crawl space is installing new/additional support posts (AKA stabilizer posts, crawl space jacks) beneath your crawl space joists.
ACM is your Long Island expert for fixing sagging floors above crawl spaces. We add support posts that sit on a concrete pad engineered to avoid settlement. The posts also won’t rot or shift like old wooden posts.
We cut and size the support/stabilizer posts to the exact height needed. The posts raise the crawl space joists, lifting the floor back into place.
With the support posts in place, your crawl space floor is held up exactly where it needs to be. Fixing the floors will also likely fix the door jam issues and prevent further wall cracks upstairs.
Crawl Space Structural Supports & Waterproofing
Since we are down in the crawl space already, many homeowners in Long Island also have us waterproof the area. We install an interior waterproofing system with a perimeter french drain connected to a sump pump, which pumps any entering water up and out of your crawl space.
The waterproofed crawl space also keeps out excess moisture, which can build up and rot away the wooden structural support beams in your crawl space. Waterproofing the crawl space can help prevent any sagging floors in the future.
