Crawl space water damage

Crawl spaces and basements are out of sight, but they contain some of the most important components of your home. Not only are water heaters and electrical systems usually run through crawlspaces, but structural components like floor joists and foundation tie-ins are accessible. Modern homes usually have a bottom to top air flow, venting any vapor or mold spores throughout your house.

Dry rot

Dry rot is a fungus that grows in exposed wood with high moisture content. Leaks, flooding, and ground water intuitions can all create the ideal environment for dry rot to grow. If these conditions are left unchecked for months or years, wood rot can degrade the cellular matrix of wood and deteriorate the structural value of beams, joists, sub flooring, and other critical components.Dry Rot Due to Construction Defect

At SFW Construction LLC, we’re experts at dry rot repair. We can evaluate what components of your home need to be replaced or patched while addressing underlying leak or flooding issues.

Mold and Pests

Fungi is not the only organism that thrives in wet environments. Mold and other pests can also take over long forgotten crawlspaces and unfinished basements. Once mold takes hold, air circulated through your crawlspace can spread mold spores into your house. Strong, musty odors coming from your crawl space van also be a sign of raccoon, rat, or other insect infestations.

After removing standing water and solving any lingering water intrusion issues, crawlspace encapsulation can be a good solution to pest infestations. Keeping the floor of your crawlspace covered with poly sheeting can make the area much less livable!

Water Vapor

Standing water, leaks, and high moisture content can lead to water vapor circulating throughout the rest of your house. Vapor circulation is associated with warped flooring, dry wall mold, and fungal growth throughout the rest of your house.

Installing a vapor barrier into your crawlspace can help you to control water vapor in your house.

We see a lot of dry rot. Window and siding tend to accumulate dry rot when exposed to water. Fortunately for exterior envelope structures, siding, trim, and windows need to be painted every few years; this means structure inspections as you can’t (or rather shouldn’t) paint over damaged siding. Crawl spaces, unfortunately, don’t get a revamp every few years. It’s not uncommon for us to hear from our customers that they haven’t done a crawl space inspection in over 10 years!

What structures are vulnerable to crawl space dry rot?

Sill plates, the wooden structure sitting directly upon your foundation, are likely to rot due to moisture wicking upwards from the foundation wall. Modern construction best practice dictates that treated wood be used for sill plates, we often see houses where untreated wood was used. Dry rot on your sill plates can lead to dry rot extending into your floor joists, band boards, and beams! At SFW Construction, we have the ability to erect temporary shoring and repair or replace sill plates as necessary.

Floor joists, which sit upon sill plates and support the sub-flooring above, rot from either excessive water vapor content, a water intrusion above, or wicking from the sill plate below. Floor joists are responsible for holding up flooring, so dry rot compromised joists can lead to safety hazards. Active dry rot will move water upward into flooring and sub flooding, exasperating the problems if not addressed in a timely manner.

Rim Joists or band boards are likely to accumulate dry rot because of the surface area they have exposed to the exterior walls. As with floor joists, band boards are susceptible to wicking because of their surface area contact with sill plates. Depending on the extensiveness of the dry rot, it may be easier to replace rim joists from the outside!

Sub-flooring, which lays upon floor joists to create a suitable base for flooring, can also decay from air with extreme water vapor content cycling up through your home. More often than not, rotten sub-flooring is due to leaking plumbing or an external envelope leak in your siding or roof. At SFW Construction, we can address all of your crawlspace dry rot challenges.
