    Benches, bridges, flower beds, and gazebos made of wood give outdoor areas a homey, welcoming feel. Wood is a favourite food of fungi and insects.

    The wood used for the exterior of a building needs to be durable and resistant to the elements. Both chemically treated and naturally rot-resistant woods are used in the construction industry.

    Although no wood is truly rot-proof, several species are suitable for outdoor usage without the need for chemical treatment. Some are extremely susceptible to decay, while others can go longer between treatments.

    Raise beds, fences, decks, and trellises made from natural wood are inviting and comfortable. Much lumber has rot prevented with chemicals. You can use these woods outside without worrying about them rotting away.

    Decks, arbours, and saunas typically made from cedar, redwood, cypress, as well as other rot-resistant woods. In addition to being resistant to insect and fungal infestation thanks to their chemical composition, these woods also have stunning hues and grains.

    In comparison to pressure- or green-treated lumber, the lifespan of naturally resistant woods is no better. Follow these guidelines to extend the life of your high-priced natural wood by decades.

    Traditionally, homes' siding, eaves, and trim were crafted from softer woods. These forests softened after being showered and sunbathed upon.

    As a result, several types of fungi thrive in damp, softwood environments. Rotting wood is typical in older buildings. When left untreated, wood rot can weaken or even destroy a home's framework.

    Wood decay can be prevented if repairs are made in time. To ensure your home's structural integrity is maintained, it's best to engage a professional restorer and request rot-resistant timbers.

    At Hitch Property Constructions, we offer timber repairs work from simple timber repair to almost new structures, renovations, and extensions.

    Why Is Wood Still Used Today?

    Color gradations, weathering, and the development of a wide range of textures through time make wood surfaces exceptionally interesting from a design perspective. From rough log posts to sanded-smooth decks, there is a vast range of aesthetic possibilities when working with wood.

    Rot-resistant wood has many potential uses, and the natural beauty and comforting associations of wood in general are well acknowledged. From a sustainability perspective, wood is a great material option when it is supplied locally and harvested sustainably.

    Exactly What Causes Wood to Rot?

    One of wood's worst enemies is fungus. However, insects are most destructive when they feast on moist, rotting wood. Insects that eat wood, like termites, often follow the fungus that cause wood decay.

    Decay fungi eat away at wood and eventually destroy it. Green plants that lack chlorophyll. Since they lack the ability to produce food through photosynthesis, they must rely on other sources. What they eat is primarily tree trunks. Fungi that cause decay eat away at the wood's density and durability.

    For decay fungi, four main things are needed.

    Why Are Some Woods More Resistant?

    Why do some types of wood hold up well on a porch while others deteriorate in a single winter? The answer is in the tree's make-up.

    • Sapwood is the wood of a tree that is immediately adjacent to the bark. It's the thin, pale layer seen in a tree cross-section just beneath the bark. Regardless of the species of tree, sapwood lacks the durability to withstand the elements for long. The resistance to decay will be low in any piece of lumber that contains a significant amount of sapwood. And its shelf life is short in the wild.
    • Quantity of extractives: The wood's colour, fragrance, and other mechanical and physical attributes are all the result of extractives. A tree's natural compounds include waxes, essential fats, resin acids, and terpenes. Slower-growing trees tend to be more durable and extractive because they have more time to develop their wood. Therefore, older trees have a greater inherent resistance to decay.

    You don't have to be a tree specialist to figure out which species of wood offer the best protection against rot. It's likely that a worker at your local wood mill and hardware store will be able to put you in the correct direction and assist you get started with woodworking.

    Before heading out to the market to seek for wood that really is resistant to rot, it is a great idea to have some notion of a type of wood you desire. When everything has been done, different varieties of wood will also have their own unique qualities, such as their resilience to weather and how long they last. Included in this category are factors including colour, grain, texture, workability, availability, and cost.

    The Rot-Resistant Woods of the World

    It's not easy to find naturally long-lasting woods. Many tropical hardwoods are naturally resistant to degradation. Tropical regions have longer shelf lives because of the increased humidity and warmer temperatures. It takes more time and effort to locate exotic woods, and they cost more than domestic woods.

    These hardwoods are listed from most decay- and rot-resistant to least, along with notes on how simple or challenging they are to deal with and any other physical properties which may make them attractive for specific applications.

    Insects and rot are drawn to softwood. Water damage is common in older homes because termites thrive on damp, rotting wood. The white pines, fir, and other soft woods that are commonly utilised in modern construction today give very little protection against termites and rot.

    Why don't we use wood that doesn't rot? We can't afford it. To avoid rot, use a rot-resistant wood from the list below.

    Use rot-proof wood for making repairs (especially exterior repairs). Wooden flooring, mantles, and interior mouldings don't require the same level of protection as external trimming, porches, and decks.

    Here are some suggestions for rot-resistant wood and why they could be appropriate for your undertaking. Price and availability may vary by region. Discover what's going on in the area by doing some digging.

    Wood with Decent Rot Resistance

    Cypress

    Ample supplies of this wood kind are uncovered all around the south-east. It's cheap, it's simple to work with, and it takes paint and stain quite well.

    Redwood

    The redwood tree is the equivalent of the cypress tree in the western United States. A kind of timber that is widely utilised for exterior purposes due to its low cost and ease of availability.

    Old-Growth Pine

    Although pine isn't inherently resistant to decay, old-growth pine has far greater resistance than its younger counterpart. Shiplap siding as well as other decorative components on the exterior of historic homes are often made from this sort of wood.

    Rot-Resistant Wood

    Old-Growth Cypress

    The variant of this durable wood obtained from old-growth trees contains noticeably more heartwood than just its contemporaries obtained from younger or second-growth trees. Because of this, it lasts longer and resists decay and insects considerably better than before.

    Cedar (Eastern White or Western Red) 

    Cedar is a great choice for external use. With its attractive grain pattern, cedar is a great material for staining. Cedar's resins can seep through other finishes if you're not using a stain-blocking oil primer beforehand.

    White Oak 

    White Oak is a native hardwood that is widely accessible in the United States and is well-known for its great durability. Wood has been used for ages to create doors, windows, high-quality furniture, and floors.

    Old-Growth Redwood

    To reiterate, the kind of this wood that comes from old-growth forests is exceptionally resistant to decay and insects.

    Pressure-Treated Pine

    Probably the most widely available and durable wood species in the USA. It's available at any hardware store and won't decay or attract pests. It can withstand being in contact with dirt without decaying and has a high paint retention rate. It's recommended to wait several weeks following installation before painting due to the chemicals used in the treatment. This is necessary to allow the chemicals to dry. You should handle it with care since as it dries it will shrink considerably.

    Extremely Rot-Resistant Wood

    Mahogany

    When it comes to hardwoods, this species is the best there is. Its great density and hardness make it resistant to decay by keeping out water and insects. Doors made of mahogany are popular because the wood looks good even before it has been completed. Paint also sticks to it extremely well. However, its high cost is justified by its durability and aesthetic appeal.

    Spanish Cedar 

    The Spanish cedar is quite dense and has a look and feel reminiscent of mahogany. While it lacks the hardness of mahogany and the expense of exotic hardwoods, its stability makes it a great choice for the construction of window panes and exterior trim. This wood has been more hard to find in recent years, but you might be lucky enough to find some in your area.

    Teak

    Because of its reputation as one of the toughest woods on the market, this tropical hardwood is frequently used for decks and porches. The wood is so durable that it may be left untreated and outside in all weather conditions without suffering any damage. Its exceptional hardness makes even basic manipulations like cutting and milling very difficult and time consuming. Holes for the screws should be pre-drilled due to its toughness.

    Ipe 

    This wood, like teak, is quite solid and heavy, making it perfect for use as decking or porching. It will look beautiful in the outdoors for decades if you keep the deep red color maintained.

    Accoya

    This new species of wood supposedly has very high rot resistance. Radiata Pine, a crucial component in the therapy, undergoes acetylation. This technique causes a chemical change in the wood that makes it resistant to decay and insect infestation as well as maintaining its original dimensions (it didn't decrease or twist). Unlike pressure-treated wood, which often contains hazardous chemicals, Accoya is not handled with anything that could potentially hurt the user. You can learn more about Accoya by reading this article.

    Exposed Wood Use

    Outdoor furniture

    The greater price tag on stylish outdoor furniture might be reasonable if you consider it an investment in materials that will stand up well over time. Over time, everything decays. Concerned that, as Wonder Bread for exterior materials, items that claim unusually extended shelf lives are actually loaded with chemicals to achieve that goal.

    Decks 

    The widespread adoption of wood decking for use around pools and outdoor showers can be attributed to the fact that it is so comfortable to walk on barefoot. An experienced builder or carpenter will know the ins and outs of making wood elements that don't soak up moisture.

    Wood post fences

    The ash juniper post fence is a good example of how to incorporate a rustic wood fence into a house landscape while still maintaining a great handmade look. In order to create a laid-back ambience, it's preferable to choose timber that hasn't been sanded smooth or shaped into ideal beams.

    Trellises 

    Allowing plants to climb a wood trellis will eventually lead to its disintegration because the plants will trap moisture against the wood, making it more prone to rot. While a metal trellis would not work for a cottage garden, a wooden one would. The rot-resistant wood trellis is ideal for twining-type vines which wrap around buildings, such as clematis, because the vines will not seek to connect their roots to the wood.

    Raised beds

    To prevent the cedar from rotting, it is important to put raised cedar beds on sand rather than soil. A geotextile or landscaping cloth can be used to separate the soil in the raised bed's interior from the wooden frame. This prevents the wood from absorbing water and decaying prematurely.

    Accents

    Wood can be utilised not just as the principal component of the a deck or pergola, but also as decorative feature in the garden. Ipe and redwood, both highly sought-after hardwoods, are regularly employed for such work. Incorporating wood as a finishing touch into a metal railing or seat prevents it from touching the ground and gives the structure a unique look.

    How to Prevent or Stop Rot

    Age or exposure to extreme conditions can compromise the durability of even the most rot-resistant woods. Under these conditions, the question of how to protect wood from decay naturally arises.

    Outdoors

    The first and most crucial step in using a wooden block in an outdoor setting is to ensure that it is made from rot-resistant material. After that:

    • Prevent as much touch as possible with the ground. When a piece of wood is resting on the ground, moisture can easily seep into the wood, inviting the growth of mould and fungus.
    • Make sure water doesn't pool on the wood by giving it a pitch.
    • Take away any overhanging vegetation. Because of the humidity, they hasten the decaying process.
    • To prevent decay fungus from using wood as a food supply, use chemical wood preservatives.
    • Paint or stain it to help prevent water damage.
    • Get rid of any pools of water.

    Fungus is less likely to take over the woodwork in the outdoor area as well as on the outdoor furniture if you are able to keep moisture out of the wood as much as possible. Preventing rot from occuring is easier than fixing it after it has spread.

    Pressure-Treated Wood

    When talking about wood, the term "pressure-treated timber" indicates that the wood has undergone a process that injects a chemical protection into the wood at a much deeper level. The pressure step occurs when the timber product is placed in a huge holding tank and the tank is depressurized to eliminate any air.

    The tank is filled with a preservative and then pressurised to drive the chemical deep into the wood. Once that's done, any leftover preservation is transferred to another system. When the wood has been extracted from the tank, it undergoes a series of operations in order to be sent on its way to the local lumberyard.

    Treated wood lasts longer because it is less susceptible to decay from fungi and insect infestation thanks to the chemical treatment. It can then be bought in stores as boards, lumber, posts, or plywood.

    The Perfect Building Material for Any Weather

    Pressure-treated wood is a great wood to utilise for outdoor building since it is weather-resistant and stable throughout the year. Any piece of outdoor furniture, swing set, swing, deck, mailbox, picnic table, or other product produced from pressure-treated lumber may be expected to last for many years, regardless of whether it was built by you or a professional.

    Is It Okay to Use Chemically Treated Wood?

    When you hear that wood has been "chemically treated," you might worry about using it in areas where children or dogs might come into contact with it, such as in a garden or a home.

    The insecticides used in pressure-treated wood are currently under review by the Environmental Protection Agency (EPA). The chromate copper arsenate (CCA) found in these materials is a carcinogenic member of the arsenic family. Restrictions on numerous CCA applications have already been imposed by the EPA.

    Currently, pressure-treated wood is treated with Alkaline Copper (AC) and Quaternary Ammonium Compounds (ACQ). Research shows that despite being much less harmful than CCA and creosote, these chemicals do not leach into soils. As a result, health hazards are mitigated but not entirely removed.

    Guidelines for the Protection of Chemically Treated Wood

    • Children should avoid touching treated wood until they have washed their hands.
    • It is not safe to put food directly onto a picnic table or other surface made of treated wood.
    • In areas where it might come into touch with food, such a garden, treated wood should not be used.
    • Indoor or outdoor, you should never burn treated wood. If you burn this wood, you'll get chemicals in your smoke and ash.
    • Do not place treated wood in close proximity to animals used for food or feed.
    • Wood that has been treated with chemicals should not be used anywhere people will be exposed to drinking water.
    • Do not use mulch or compost made from treated wood or sawdust.
    • Do not clean or bleach treated wood with substances like sodium hypochlorite, sodium hydroxide, sodium percarbonate, citric acid, or oxalic acid. As a result, the wood may emit chemicals that are harmful to humans when inhaled or made contact with.

    The moisture content and exposure to sunshine are the key contributors to the development of wood rot. Moreover, wood can be harmed by a wide variety of creatures, including insects, fungi, and others. It is especially crucial to use rot-resistant wood when the wood will be in close proximity to the soil, as in an elevated garden bed or a vine trellis.

    Because it allows moisture to soak into the wood, which causes it to expand and fracture as an outcome of the reaction, soil contact exposes the timber to the risks of mould and fungus. You can avoid direct contact with the earth by using certain construction techniques, and you can avoid having water pool on top of stacked wood by changing the way it is stacked. The rotting process is hastened when plants and vines grow over decaying wood because of the increased moisture content.

    FAQs About Wood Rot

    Sand the damaged area with medium-grit sandpaper, following the direction of the wood grain. The goals are to smooth the wood, remove loose paint, and prepare the surface for accepting new primer and paint.

    Moisture can easily cause rotting and splitting in wood, and a new coat of paint will not do anything to fix the problem. When water soaks into wood, it can cause wood to expand and swell as well as deteriorate to the point of falling apart. So, painting over the problem only won't fix it, it will just add to it.

    Use a polyester filler to rebuild rotted or damaged wood. You can mold and shape it to match the original wood profile. It takes paint well and won't rot.

    Dry rot is a type of dampness primarily found in aged homes and buildings. If left untreated, it can cause wooden structures to weaken and the building's foundation will get disturbed.

    If the wood can be salvaged, the first stage to dealing with decay is to cut out the affected area. If the wood is wet, allow it to dry before filling with a wood filler such as Cuprinol Ultra Tough Wood Filler. For best results, pre-treat the repair area with Cuprinol Clear wood preserver and allow it to dry.

    Conclusion

    Fungi and insects love to eat wood. Wood rot can weaken or completely destroy a building's framework if not handled. It's common practise to use chemically treated woods in construction, but naturally rot-resistant woods are also widely employed. If you stick to these rules, you can make your expensive natural wood last much longer. Wood decay fungi are responsible for the ultimate destruction of wooden structures.

    Most trees that grow more slowly are also more robust and useful for lumber. Inherently, older trees are more resistant to degradation because of their advanced age. It's important to remember that different types of wood, even within the same species, will have their own distinct characteristics, such as varying degrees of resistance to the elements. Softwood is more susceptible to insect infestation and fungal decay. When fixing things, use wood that won't decay (especially exterior repairs).

    Stopping rot from starting is far simpler than trying to repair it after the fact. Because of its durability and stability regardless of the season, pressure-treated wood is an excellent material for outdoor construction. Chemically treated wood shouldn't be used anyplace people might come into contact with potable water. In situations where the wood will be in direct contact with the soil, like in an elevated garden bed or a vine trellis, rot-resistant wood is essential.
