LP Smartside Siding | Smith Builders | Bangor, Ellsworth, Belfast, Maine

Freeze-thaw cycles and humidity swings cause many siding materials to expand, contract, and eventually fail at fastener points or seams. Smith Builders installs LP Smartside engineered wood siding on residential and commercial buildings throughout Maine, serving clients who need the appearance of wood without the dimensional instability that causes traditional wood siding to warp in climates where temperature and moisture levels change dramatically between seasons. LP Smartside uses strand technology and resin binders treated with zinc borate for resistance to fungal decay and termite damage, addressing two common failure modes in wood products.

The manufacturing process compresses wood strands under heat and pressure with weather-resistant resins, creating panels and trim that resist the swelling and shrinking that occurs when natural wood absorbs and releases moisture. Installation follows standard siding practices with proper flashing, drainage plane integration, and fastener placement that allows the material to move slightly without telegraphing fasteners or buckling between attachment points. The factory-applied primer provides a consistent base for finish coats and seals edges that would otherwise absorb moisture during rain events.

Schedule a material consultation to compare LP Smartside profiles and discuss finish options for your building type.

Traditional wood siding absorbs moisture along growth rings and grain patterns, creating uneven expansion that leads to cupping, twisting, and fastener withdrawal. LP Smartside eliminates directional grain by using wood strands oriented for strength and treated throughout rather than just surface-coated, so moisture that does penetrate encounters preservative-treated material rather than untreated core. The SmartGuard process adds a layer of protection during manufacturing that continues working even if the finish coat develops minor cracks or wear over time.

Once installed, you'll have siding that maintains consistent reveal lines and flat surfaces without the warping that appears on natural wood after several freeze-thaw seasons. Trim boards stay straight along their length, and lap siding remains tight at seams rather than opening gaps as boards shrink. The consistent profile also means paint or stain wears evenly across the surface instead of failing first at raised grain or knots where natural wood absorbs finish at different rates.

LP Smartside comes in multiple profiles including lap siding, panel formats, and trim components that coordinate across the building exterior. The material accepts paint and solid stain readily, and factory priming means the first finish coat adheres uniformly. Fastener schedules and joint detailing differ slightly from natural wood due to the engineered material's different expansion coefficient, so proper installation requires following manufacturer specifications rather than using traditional wood siding techniques.

What makes LP Smartside resist moisture better than standard wood siding?
The zinc borate treatment penetrates throughout the strand matrix rather than just coating the surface, and the resin binders used in manufacturing repel water more effectively than the natural lignin in untreated wood. This combination reduces moisture absorption that leads to swelling, rot, and fastener failure in traditional wood products.
How does this siding perform in Glenburn winters compared to fiber cement?
LP Smartside weighs less than fiber cement, which simplifies installation and reduces structural load, while providing similar resistance to freeze-thaw damage. The material doesn't become brittle in cold temperatures the way some cement products can, though both materials outperform natural wood in dimensional stability during seasonal changes.
What warranty coverage applies to LP Smartside installations?
Warranty terms depend on proper installation following manufacturer specifications and use of compatible finish products, with coverage typically addressing manufacturing defects and treatment effectiveness rather than finish durability. Smith Builders ensures installation meets requirements that keep factory warranties valid.
How often does LP Smartside need repainting compared to natural wood?
Finish lifespan depends on exposure, color choice, and product quality, but the dimensional stability of LP Smartside means paint doesn't crack from substrate movement the way it does on wood that swells and shrinks. Most installations need refinishing every eight to twelve years on weather-exposed elevations.
When should I choose LP Smartside over vinyl or aluminum siding?
Engineered wood provides a milled appearance with visible grain texture that resembles natural wood more closely than extruded plastic or formed metal, making it appropriate where design standards favor traditional aesthetics. The material also accepts fasteners anywhere along its length for attaching shutters, fixtures, or trim without requiring backing.
