What is Dry Rot and How Can You Prevent It?

Dry rot is a common problem in residential and commercial buildings. It can affect virtually any structure with wooden components and can mean thousands of dollars in damage if it is left untreated. Even when it is removed, measures must be taken to ensure that it does not recur in the future. Working with a dry rot repair service is critical to ensuring your home or commercial property is safe and structurally sound.

What is Dry Rot?

Dry rot, or wood rot, is wood decay that is caused by fungi. It happens when wood becomes too wet and its moisture content grows to over 20%. Wood that is left damp over a period of time will begin to deteriorate. At that point, the wood-destroying fungus attacks the timber, causing major damage. It is one of the most dangerous forms of fungal decay, as it can spread quickly throughout wood and into masonry. It can also permeate beams and structural timbers, door frames, walls, and flooring of properties of all ages.

Where Does Dry Rot Occur?

Because dry rot spreads so quickly, it can affect virtually any part of a building with wood. However, some parts and spaces are typically more damp or susceptible to standing water than others, making it easier for the fungi to flourish. The following parts of a building are most commonly affected by dry rot:

How Does Dry Rot Spread?

Dry rot fungus produces spores. These spores generally travel through the air. They germinate when they reach wood that has been exposed to high moisture levels or standing water. In order to grow, these fungal spores need a food source, which is the wood they permeate. They also need oxygen, and ideally, temperatures between 71- and 77-degrees Fahrenheit. If it is not stopped by a dry rot removal service, it will cause the wood to disintegrate, which can lead to collapse and damage to other structural elements.

What Does Dry Rot Look Like?

Dry rot presents itself in different forms depending on which of the following four stages of its life cycle it is currently in:

Signs of Dry Rot

In some cases, dry rot can be spotted through visual inspection. Otherwise, there are some tell-tale signs even when it is not visible. If you notice the following in your home or commercial property, call a local dry rot repair service immediately:

How Can Dry Rot Be Prevented?

Once you have identified dry rot in your home or commercial building, it is absolutely essential that you make an appointment with a dry rot service as soon as possible. A professional can extract the fungi, repair the damaged structural elements, and ensure that the rot does not return in the future. Fixing the source of the issue so that it does not happen again is just as important as removing the fungus. In order to prevent regrowth, you will need to stop the source of moisture and make sure it is well-repaired and fortified against leaks. All infected timber and wood must be removed, and the area must be treated with fungicide treatment to create a barrier against fungal growth. The wood then needs to be replaced with pre-treated timber to prevent future infestation.

Further measures may be necessary depending on the situation, such as the addition of a dehumidifier to control moisture levels. In the future, it is a good idea to check that your doors and windows are sealed with caulk, your gutters are cleaned regularly, and your entryway doors are covered to keep rain away. Dry rot can not be definitively prevented from coming back after removal without the assistance of a professional, so be sure to contact a local wood rot repair service.
