Crawl Space Repair

  • There is no one size fits all approach.  The solution to remove moisture from your crawl space needs to be designed specifically to address your issues and to accomplish your goals. 

  • A crawl space is an unoccupied, unfinished, narrow space within a building, between the ground and the first floor. The crawl space is so named because there is typically only enough room to crawl rather than stand.

  • There are ways to fill it in but it is not cost effective to do so.  You can also turn it into a basement but it is a difficult, expensive process to do so.

  • Similar to a basement.  An interior drainage system, sump pump, and crawlspace encapsulation system is the best way to address.

  • There is no one size fits all approach.  The solution to waterproof your crawl space needs to be designed specifically to address your issues and to accomplish your goals.

Dry Rot Damage Repair

    • Remove Damaged Wood: All wood that shows decay or visible fungus should be removed.
    • Remove Materials Near Damage: Plaster, paneling, linings, and ceilings around the dry rot areas should also be removed.
    • Wire brush Affected Area: Using a wire brush, loose material is removed from all surfaces including metal, masonry, and pipes. Resulting dust and debris is removed as well.
    • Disinfect area: A disinfectant is applied to all wood, masonry, and exposed soil.
    • Rebuild: Substantially rot-damaged beams, joists, and posts are replaced with pressure-treated wood.

  • Likely any wood that has damage from dry rot needs to be replaced. In fact, there is up to a 75% loss in the toughness of the wood with just a 1% decrease in the weight of the wood.

  • It really depends on the amount of the damage. But factoring in the deconstruction, the replacement of the damaged wood, clean-up of affected areas, and whether you do-it-yourself or hire professionals, the cost of repairing wood rot, can be significant.

  • It can lead to future problems with dry rot if it is not treated properly. It will not get better on its own.

  • The short answer is, “Yes, but…” If you remove previously damaged wood and other materials, remove the source of moisture and humidity and treat the remaining wood with a chemical the hinders the growth of wood rot, you may stop the growth of further rot.

  • Probably not. Wood damaged by wood rot is not salvageable and should be replaced as soon as possible to keep the rot from spreading.

Wood Damage Repair

  • If your structural support beams are rotted, a sister beam of new wood may be installed along the old one to add structural strength. Be sure to remedy the source of wood and use treated wood to prevent a future incursion.

  • A lot depends on whether you’re hiring a professional or doing-it-yourself. It also depends on the length and width of the wood you’re replacing and the difficulty of replacement – for example, do you have to tear up the floor to access. That said, replacing floor joists in a crawlspace can cost from $100-300 per joist if you can easily access the joists. If they are insulated or have any type of covering or your pro has to go through the floor, you could be looking at $1,000 or more.

  • Wood rot is caused by a type of mold or fungal growth which eats away at your floor joists' strength and ultimately its load-bearing capabilities. The fungal growth that causes dry rot begins as a spore before it starts growing in high-humidity environments, such as the crawl space of your home.

  • In a word, “Yes.” Any kind of mold or fungus spores can compromise your respiratory health. Left untreated, it can develop into wood rot and weaken the structural integrity of the home and ultimately cost you thousands of dollars in repairs.

  • There are many opinions out there on the internet about opening them in the Summer and closing them in the Winter. Our opinion is simple and that is close them – all the time. Seal off your crawl space from the humidity and crawling things. We go a step further by saying you should encapsulate your crawl space, entirely.  

  • Mold can begin growing in the right conditions within 24-48 hours. And, there is up to a 75% loss in the toughness of the wood with just a 1% decrease in the weight of the wood. So, the short answer is “really quickly” if you don’t take the appropriate action to remedy the situation.
