Having to replace the support beams just because your floor is sagging can be a real problem. Before you start thinking about that, you’ll need to get in contact with a foundation and crawl space expert who can inspect the damage and find the best course of action.
If Replacement is Necessary
Once the inspection is done, the contractor will let you know how to proceed. There’s a chance that a full replacement of the wood in your crawl space is unnecessary and only certain parts need to be reinforced. Remember, the wooden structures in your crawl space that support your home isn’t just limited to the beams.
The sill plate, band joist, the insulation, and the concrete walls are all part of a symbiotic structure that works together to support your home. If the contractor inspects the crawl space and talks about replacing things, don’t worry: It doesn’t automatically mean the whole crawl space needs to be completely remodeled.
If Replacements Aren’t Necessary
If nothing in the crawl space needs to be replaced, the most common way to fix sagging floors is by using joist stabilizers. They are specialized jacks that hold up beams and evens the flooring in your home. Steel beams can also be added for extra support. Nailing together a sister joist is another common way to strengthen the joists. This is especially good for wood that has been cured of dry rot and just needs a little extra help supporting the flooring.
The contractor might suggest at least installing a sump pump if full encapsulation isn’t something you’re able to do at the moment. After going through the trouble of adding new support for your sagging floor, taking care of it would be wise.
