Places In Your Home To Look For Rotted Wood

Decaying wood inside or outside a house makes the structure less stable and more prone to collapse, and can also spread rapidly if left untreated. To keep decay from spreading around your home, you should know the typical places to check for rotting wood on your property.

Common places to find decayed wood inside your home include under sinks, in attic beams, and in your basement. Cabinets, windowsills, and entryways can also exhibit wood rot. Fences, outdoor furniture, porch and patio decking, and your roof are also places to look. Musty smells, visual signs, and a soft texture are all easy-to-spot symptoms of wood rot.

If left untreated, decaying wood can cost thousands of dollars to fix, and it can even make your home unsafe to live in. But you can’t fix this problem if you don’t know it exists. The best way to stop wood rot from spreading is to catch it before it gets out of control. Below is a list of all the most common places both inside and outside your home where you are likely to spot this issue.

Four Ways To Easily Recognize Rotted Wood

1. Visual

As wood begins to decay, you'll often see clues that something’s wrong. One of the most common signs is mold. If you see patches of fuzzy mold growing on any wood, investigate further. Rotting can also look like discoloration or deteriorating wood. If you see wood crumbling or with holes, that's a bad sign. Taking a close look at vulnerable wood in your home is a great way to stop rot before it spreads.

2. Texture

Beyond what you can see, wood may also feel different as it starts to rot. It can become brittle and flaky, soft and spongy, or crumble. Check the texture, as this is often the most effective way to confirm rotting wood and identify affected areas.

3. Touch

One great way to confirm rotted wood is to perform the poke test. If you poke the wood with your finger and it is clearly soft, or if it flakes away or crumbles, then there’s a good chance it is rotting.

4. Smell

While wood doesn't always take on a new smell as it rots, it often carries a musty or decaying odor, especially if it is rotting from water exposure. Any time you notice musty or rotting smells, it’s a red flag. Find the source of the unpleasant odor and confirm whether any wood in the area is decayed.

Six Places Inside The Home To Look For Rotted Wood

1. The Basement

Since wood often decays in damp, dark areas, the basement is a common place to find rotting wood. Basements are often the most humid area in the home. Water leaks, condensation, and close proximity to the ground make this room a place where wood-killing mold can thrive.

If you have wood in your basement, make sure it is dry, properly sealed, and treated to prevent mold growth and wood rot. Investing in a dehumidifier is a great way to reduce moisture levels in your basement, which can also decrease the likelihood of wood rot.

2. Under Sinks

Leaking pipes and other water leaks often cause wood rot, and few places in the home have more of these than under a sink. Regularly inspect cabinets and floors around your sinks to confirm there are no leaks, which can rot wood, cause structural damage, and cause toxic mold that can be very expensive to fix if left untreated for months.

3. Windowsills 

If you live in an older home, you likely have window treatments and sills made of solid wood. While these old-school elements have beautiful antique charm, windowsills are vulnerable to wood rot. Check them regularly for signs of wood rot, especially the texture. If they are soft and spongy, you likely need to replace them with new material.

4. Entryway

Because an entryway sees heavy traffic and often wet shoes and boots, it is more susceptible to all types of damage, including wood rot. If you live in a particularly wet climate and your entryway is made of wood, inspect your entryway seasonally, especially before winter, because decaying wood won’t keep out cold air properly.

5. Attic Beams

A roof is one of the most important structures on any home. If it’s vulnerable, all sorts of serious and expensive issues can arise. Attic beams are often made of wood, and if your roof is holding moisture, or worse, leaking, the beams are vulnerable. Moisture from outside can cause wood-eating fungus to thrive in your attic. Regularly check the structural integrity of wooden attic beams to ensure they are strong and healthy.

6. Around The Toilet And Shower

Your bathroom is often the most humid room in the home, and it is prone to mold and mildew. Mold can grow on all sorts of surfaces, but it is particularly dangerous when it grows on wood. Keep your bathroom dry. Run the exhaust fan whenever you shower, leave the door open, and clean up any water puddles as soon as you notice them. This will reduce the risk of mold growing on wood in your bathroom.

Five Places Outside Your Home To Search For Rotted Wood

1. Fences

Fences come in all sorts of materials, from chain-link to plastic, but many are made of wood. If you have a wood fence, check it regularly for rot. If you haven’t sealed or painted the fence in years, it is more susceptible to decay. Address rotting parts of the fence or the issue can spread and result in a costly repair.

2. Patios And Deck Floors

Wooden patios and decks can add value to your home, but only if they are in good condition. If you don’t clean and seal a deck and patio properly, fungus can grow rapidly. Many neglected decks rot, and the damage can be so severe that you may need to replace the entire structure, which can cost thousands of dollars.

3. Outdoor Furniture

Wooden furniture that lives outside year-round needs protection and to be inspected regularly. Even strong hardwoods can rot in unforgiving conditions. In addition to checking the furniture, you should consider storing it in a dry place out of the sun when it’s not in use. Proper storage can extend furniture life by many years.

4. The Roof And Eaves

Your roof, and the eaves in particular, see a lot of lingering moisture year-round. If your roof is old or damaged, water can become trapped inside and cause it to rot from within. The eaves may experience rot over time, especially if the gutters are old, damaged, or were improperly installed. Whenever you inspect the roof, ensure you check both for signs of wood rot.

5. Siding

If your home’s exterior is wood siding, inspect it regularly for damage. Unlike damaged vinyl siding, issues with wood can spread rapidly. Closely inspect discolored or damaged siding on your home’s exterior. If you see signs of rot, replace the pieces and check the surrounding area for damage.

Summing Up Places To Look For Rotted Wood On Your Property

Wood rot is a serious problem that can appear seemingly out of nowhere, and then spread rapidly. It can cause structural damage to your home, which can be expensive to fix. To prevent these costly problems, check areas of your property prone to wood rot.

Your attic beams, roof, and eaves are crucial areas to check regularly, as is your basement. Wood often rots in moist areas, including under sinks, in bathrooms, on windowsills, and at entryways. Outside your home, check your wooden decks, fences, and outdoor furniture, as they are all prone to rot, especially when neglected.
