Dry Rot: Is Your Home at Risk?
Unexpected home repairs are frustrating, and even more so when you find dry rot in your crawl space. Many homeowners know about dry rot but may not fully understand its definition, implications, or potential damage. If you’re unsure whether you’re seeing dry rot or simply want to learn more, this page is here to help.
Keep reading to learn how proper dry rot identification can help prevent damage and explore repair methods to address issues before it’s too late.
What is Dry Rot?
Dry rot is wood decay caused by the Serpula lacrymans fungus. It thrives in dark, moist environments and spreads rapidly across wooden structures, such as crawl space support beams and piers. This fungus can also travel through plaster and masonry, affecting other wooden elements even after the wood begins to dry.
Optimal conditions for dry rot growth include temperatures between 68 and 72 degrees Fahrenheit and wood moisture content between 20 and 40 percent.
What Are the Signs of Dry Rot?
Dry rot can be challenging to identify, as it is often mistaken for mold. However, recognizing the signs as soon as they become evident helps prevent dry rot damage to your home. Here’s what to look for:
- Musty Odors: Stale, musty odors and poor indoor air quality may indicate mold or dry rot.
- Brittle or Cracked Wood: Deep cracks, brittleness, and crumbling indicate wood affected by dry rot.
- Wood Discoloration: Affected wood becomes yellow or dark brown as it deteriorates.
- Mycelium Growth: Fluffy white or grayish mycelium that looks like cotton wool may develop on affected wood surfaces.
- Fruiting Bodies: Mushroom-like or bracket-like fruiting bodies with a reddish-orange color may develop on wood surfaces.
- Spore Dust: Reddish-brown or orange dust may be visible around the affected area.
- Structural Damage: Sagging floors and uneven surfaces may indicate structural failure caused by dry rot.
You can prevent dry rot damage by recognizing, identifying, and addressing the signs of dry rot as soon as they become visible. Contact Groundworks for a free inspection if you suspect your home is at risk. We repair dry rot in wood with specialized solutions tailored to your home and budget.
What Causes Dry Rot?
Moisture is the primary cause of dry rot, but it’s not the only cause. Other factors contribute to dry rot growth, including:
- Construction Defects: Leaky roofs, faulty gutters, and dampproofing can lead to moisture accumulation in wooden structures.
- Untreated Wood: Wood lacking protective fungal treatments are more susceptible to dry rot.
- Plumbing Leaks: Leaking pipes allow moisture in areas where it shouldn’t be. This moisture can lead to dry rot.
- Unencapsulated Crawl Spaces: Unencapsulated crawl spaces are vulnerable to moisture and outdoor elements that cause dry rot, as they lack proper waterproofing protection.
- Poor Ventilation: Condensation, high humidity, and dampness caused by poor crawl space ventilation foster fungal development.
These conditions create an ideal environment for dry rot. If you notice signs of dry rot, contact Groundworks for a free inspection and expert advice on the next steps.
How to Prevent Dry Rot Damage
So far, we’ve learned the signs of dry rot and its causes. Now, let’s discuss how to prevent dry rot damage. Homeowners protect their properties from moisture and structural damage with the following encapsulation strategies:
When used together, these components provide comprehensive crawl space protection. Crawl space encapsulation prevents ground moisture seepage and infiltration, preventing high humidity and condensation that leads to mold growth, dry rot, and structural damage.

Dry Rot FAQs
Most standard homeowner’s insurance policies do not cover dry rot, as it is considered a maintenance issue resulting from gradual deterioration. Insurers typically view wood rot as a homeowner’s responsibility to prevent it through regular maintenance and moisture control. Only in rare cases involving sudden, unexpected events might partial coverage be possible.
One of the major reasons for bouncy floors is wood rot. Whether an expert has told you that you have wood rot or you just suspect it due to your bouncy floors, you might worry that staying in a home with wood rot is dangerous. Here’s a full run-down of the information regarding the dangerousness of wood rot itself.
- Toxicity of Wood Rot
Because wood rot is a fungal infestation, many homeowners associate mold with wood rot. Mold can be extremely dangerous just to be around; it can exacerbate allergies and asthma, making it a problem in any home. However, wood rot itself is not toxic, so it isn’t dangerous in that manner.
What can be dangerous, however, are the pests that are attracted to rotting organic material. The most obvious pests that thrive in these conditions are cockroaches, but there are others. The droppings and bacteria that come with pest infestations can be very damaging to your health. As well as being unhygienic, they can cause skin rashes and respiratory problems.
- Compromised Structures
Where the dangers of wood rot lay are in how drastically and quickly it can compromise your home. Wood is a primary component used to build most homes. In many cases, wood comprises the framework of a house. This serves as its skeleton, as it were. Left to its own devices, wood rot will continue to eat away at these essential structures until the home is unsafe to live in.
If you have drywall panels in your home, they will succumb to things like dampness, wood rot, and termites far more quickly than thick, wooden support beams. Of course, the fallout of damaged drywall panels is far less severe than the potential outcomes of a rotting support beam or a roof joist infested with termites.
- Difficult to Fix
Another reason that wood rot can seem very dangerous is because it’s immensely difficult to fix, especially if you ignore it for a long time. If you leave the wood rot for a very long time, allowing it to keep eating away at your home’s walls and floors, you could end up paying thousands upon thousands of dollars to fix the problem.
There’s very little that you can do other than to cut the rot out. This is fairly inconvenient when it’s a few floor support joists, but when it comes to replacing structural support beams, you could be looking at an immense amount of time and money. This, of course, is a homeowner’s worst nightmare, but GroundWorks has options in place to help with even the worst-case scenario.
You might wonder why you need to invest time and energy into keeping your crawl space dry in the first place. Mostly, this is a health and safety risk. Ensuring that your crawl space remains sanitary is important for the health of your family.
- Water Damage
Water damage can develop from repeated exposures to water. There are many ways that water can impact your home’s structure, including both waterlogging and the growth of fungus.
Supports and floor joists can be impacted by this excessive moisture if wood rot spawns. Wood rot readily devours wood, and left alone, it can compromise your home’s structural integrity. Your insulation is also at risk of mold and mildew if it isn’t made from a resistant material.
- Air Quality
Crawl spaces infected with wood rot, mold, or mildew will also lead to a change in indoor air quality. These organisms spread by releasing spores. As the humid air rises into the home, these spores are carried up as well.
Issues with air quality can impact the comfort and well-being of your family, especially if they have allergies. Plus, it can cause mold and mildew to grow in the rest of the home as well.
