Siding
Composite Siding
Composite siding offers a deeper profile and a truer shadow line than typical vinyl siding. These engineered wood and polymer products are designed to replicate the appearance of traditional wood, enhancing strong architectural details on a house. It provides a distinct aesthetic that can bring definition back to classic New England home designs.
The Makeup of Composite Siding Products
Composite siding blends wood fibers with resins and waxes, often treated for rot and insect resistance. Engineered wood products, like LP SmartSide, are factory-primed and designed for consistent finish and dimensional stability. These materials offer a more substantial appearance than many vinyl options, allowing for deeper grooves and profiles that hold a distinct shadow line.
Both engineered wood and polymer-based composites provide a balance between the affordability of vinyl and the robustness of fiber cement. They resist impacts and moisture effectively, offering a lifespan typically ranging from 25 to 35 years when installed correctly.
Installing Composite Siding: A Technical Overview
Installation begins with careful removal of old siding and any damaged sheathing. A weather-resistant barrier, such as house wrap, is then applied to protect against moisture intrusion and improve energy efficiency, shingled from bottom to top. Proper flashing around all windows, doors, and penetrations is critical to prevent water entry.
A starter strip provides a level base for the first course of siding. Individual composite panels are cut, fastened according to manufacturer specifications, and overlapped for a watertight seal. Each piece requires careful alignment for consistent reveals and straight visual lines.
Finally, trim boards are installed around openings and at corners. All gaps and joints are sealed with high-quality exterior sealant, and exposed fastener heads are typically filled. For primed composite products, a final coat of paint completes the finish.
Choosing Composite: Where It Fits Among Siding Materials
Composite siding bridges the gap between vinyl and fiber cement in both cost and visual depth. Vinyl siding, at $4.5 to $8 per square foot installed, offers a flatter profile that can diminish architectural details. Fiber cement, at $9.5 to $16 per square foot installed, provides excellent durability and holds its profile well, but is heavier and more labor-intensive.
Priced at $7.5 to $12.5 per square foot installed, composite siding offers a substantial look and feel, resisting the flattening effect on architectural features, without the full material weight or higher installation cost of fiber cement. It is ideal for homeowners who want to accentuate the existing character of a New England colonial or shingled coastal cottage with deeper shadow lines.
If lowest upfront cost is the priority, vinyl might be better. If extreme longevity and minimal material expansion are paramount, fiber cement could be more appropriate. Composite balances these considerations effectively.
Timeline for a Composite Siding Replacement Project
The duration of a composite siding project depends on the home's size and complexity. For a typical 1,800 square foot home in Massachusetts, a full re-side can take approximately 10 to 20 working days with a standard crew. This timeframe assumes reasonable weather conditions.
Factors extending this timeline include intricate architectural details requiring more cutting, extensive demolition, or unexpected repairs to underlying sheathing. Steep rooflines or multiple gables increase labor. Persistent rain or high winds can also cause delays, as house wrap application and painting require dry conditions. Older homes with original board sheathing may need additional preparation.
Understanding the Investment in Composite Siding
Installed engineered wood siding typically costs $7.5 to $12.5 per square foot, covering materials, labor, and basic trim. For a full re-side of an 1,800 square foot home, similar to those in Rhode Island or Connecticut, the total project cost would fall within the broader $14,000 to $38,000 range for comprehensive siding replacement, which spans vinyl through fiber cement.
Cost variance is driven by several elements. The specific brand and profile of the composite material, plus the home's exterior complexity (number of windows, doors, corners), directly impacts labor. Extensive trim work around features adds material and labor expenses.
Further drivers include existing substrate condition; significant sheathing repair adds to the budget. Disposal fees for old siding and regional labor rates across Massachusetts, Rhode Island, and Connecticut also contribute to price differences.
Avoiding Common Problems in Composite Siding Installation
Improper composite siding installation can lead to long-term issues. Inadequate moisture management is a common problem; if the weather-resistant barrier or flashing is faulty, water can penetrate the wall. This trapped moisture causes rot in the underlying wood and potential delamination of some composite products.
Incorrect fastening is another frequent error. Using the wrong fastener type, or placing them too tightly or loosely, restricts the material's expansion and contraction. This can cause panels to buckle, warp, or crack, creating an unsightly and vulnerable exterior. Manufacturer guidelines for fasteners are specific for a reason.
Incomplete sealant at joints and around trim also allows water entry, compromising the paint finish on factory-primed products, leading to peeling. A poorly executed installation shortens the siding's lifespan, requiring costly repairs sooner than the expected 25 to 35 years.
Composite Siding Across New England Architectural Styles
New England's diverse architecture presents specific considerations for composite siding. For triple-deckers in cities, composite can replicate traditional clapboard with deeper shadow lines than vinyl, while offering better durability than natural wood. Their tall facades benefit from precise installation and proper scaffolding access.
Postwar capes and center chimney colonials benefit from composite's robust appearance, which enhances window and door surrounds. When replacing existing wood siding on these homes, ensuring sound and level board sheathing is crucial. This prevents new composite panels from laying unevenly.
For shingled coastal cottages, composite products can offer a low-maintenance alternative to cedar shingles. While not identical to real cedar, these composites resist salt spray and moisture better, reducing the need for frequent staining or painting. Mill worker housing gains significant aesthetic and durability upgrades with composite, also improving energy performance with proper insulation.
Key Elements of a Detailed Composite Siding Quote
A thorough composite siding quote should clearly itemize all project components to avoid unexpected costs. It needs to specify the exact type, brand, profile, and finish of the composite material, along with the square footage of siding and linear footage of trim, fascia, and soffit materials.
Beyond the panels, a comprehensive quote details the underlayment system, explicitly naming the weather-resistant barrier. It must include specifications for all flashing around windows, doors, and roof intersections, noting new drip edges. Demolition of existing siding and its disposal, including hauling fees, should also be clearly outlined.
The quote should specify exterior finishing details, like paint coats for primed products or if pre-finished materials are used. Lead paint abatement on older homes should be addressed if applicable. Finally, it should list allowances for unforeseen repairs to sheathing or framing, explaining how such issues will be handled if discovered. A thin, lump-sum quote carries higher risk.
Common questions
Composite siding, particularly engineered wood products, typically offers a lifespan of 25 to 35 years. This duration relies on proper installation, including a robust weather-resistant barrier and correct fastening methods. Regular maintenance, such as cleaning and timely paint touch-ups for primed products, helps maximize its longevity.
Composite siding generally provides a more substantial and authentic wood appearance than most vinyl products. It holds a deeper profile and a truer shadow line, enhancing architectural details. Vinyl siding often has a flatter profile, which can diminish a home's visual depth.
Yes, engineered wood composite siding is designed with enhanced resistance to pests and rot. Products like LP SmartSide are treated with zinc borate, a natural additive that protects against fungal decay and termite infestation. This treatment contributes to a resilient exterior, especially important in humid New England climates.
Many types of composite siding, especially engineered wood products, come factory-primed and are designed to be painted. This allows homeowners to select a custom color to match their home's aesthetic. Painting adds another layer of protection to the siding, and periodic repainting is part of its long-term maintenance.
Composite siding is a low-maintenance material compared to natural wood. Regular cleaning with a soft brush, mild detergent, and a garden hose rinse is usually sufficient to remove dirt. For painted composite, periodic inspection for paint chips and timely touch-ups are necessary to maintain its protective finish.
Composite siding can suit historic New England homes where preserving detail with less maintenance is key. Its ability to hold a deeper profile and mimic wood grain can enhance historic character without the upkeep of solid wood. However, for truly historic structures, preservation guidelines may recommend authentic materials.
