Upgrading your home’s exterior with low-maintenance materials can shrink your to-do list and boost your curb appeal. These durable options save you time and effort and also maintain their appearance for years before needing attention. From weather-resistant trim to long-lasting siding and decking, homeowners can easily minimize upkeep without compromising on style or quality.
Types of Low-Maintenance Exterior Materials
Before we dive into specific products, let’s look at the different materials you may encounter when shopping for low-maintenance exterior fencing, trim, siding, and decking.
Poly-Ash
Poly-ash, marketed under the name TruExterior, is a material composed of adhesive polymers and fly-ash recovered from coal-burning power plants. Its unique composition allows for uniform milling into paint-grade exterior products such as siding, molding, and trim.
TruExterior products remain stable across various temperatures. This helps extend the life of any paint you apply. Poly-ash can even survive ground contact, making it versatile for different exterior applications. All TruExterior products come with a 20-year warranty.
Cellular PVC
Cellular PVC is an advanced form of vinyl that offers the look and feel of wood without wood maintenance issues like rotting, warping, and splitting. Nitrogen gas is injected into the vinyl during cellular PVC manufacturing, causing it to swell and create a cellular structure. The resulting product has the same density and dimensions as solid pine but is free from defects, immune to decay, and resistant to insects.
This material is an excellent choice for exterior applications like trim, moldings, and siding. Note that cellular PVC expands and contracts lengthwise with temperature changes, so you’ll need to take those changes into account during installation for a seamless finish.
Engineered Wood
Engineered wood is a versatile material created by reconstituting wood into stronger, more stable products. It involves slicing wood into veneers, flakes, or strands and gluing them back together to form boards, beams, or sheets. While engineered wood is stronger and more stable than natural wood, it’s more susceptible to moisture damage.
Commonly used in interior applications such as framing, flooring, and cabinetry, engineered wood requires thorough saturation with preservatives to withstand outdoor conditions. This process enhances its durability, making it suitable for exterior use in fencing and other outdoor structures.
Fiber Cement
Fiber cement is a composite material that combines wood fiber with cement, creating durable siding. This unique blend preserves the wood fibers in a high-pH, rot-free environment for a strong and crack-resistant product. Temperature changes don’t affect fiber cement siding, so paint lasts significantly longer. It’s heavier than some alternatives.
Although fiber cement isn’t entirely immune to moisture, proper installation and maintenance can help prevent water absorption. Prime or caulk cuts and overdriven nails in your fiber cement siding or trim, and keep them clear of the ground and adjacent roof surfaces.
Composite Decking
Composite decking has evolved significantly since its inception, offering homeowners a durable and low-maintenance alternative to traditional wood decking. Though originally made from recycled milk jugs melted and mixed with wood fiber, modern composites incorporate various materials to achieve specific performance characteristics and match different price points.
The best composite decking products have a cap layer of acrylic, which is a UV-resistant polymer that you can color and texture to mimic wood grain. This protective layer enhances the deck’s appearance and provides superior resistance to decay, insect damage, and fading. The textured surface also helps prevent slips, especially when the deck is wet.
Examples of Low-Maintenance Exterior Materials
Now that you know more about the materials available, let’s explore a few specific products we recommend.
