What Is Gentek Fairhaven Sound?

Fairhaven Sound Single Select is Gentek’s specialty polypropylene siding collection designed to reproduce the appearance of shakes, scallops, and shingles. Polypropylene siding is polymeric cladding, but it is not identical to conventional PVC vinyl siding.

Gentek currently presents four Fairhaven Sound profiles:

• Traditional Shake: a relatively regular shake profile with cedar-inspired texture.
• Scallop: a rounded lower edge that creates a more decorative pattern.
• Cape Cod Shingle: a shingle-inspired option with a controlled, traditional rhythm.
• Hand-Split Shake: a more irregular, rustic shake expression.

Profile names describe visual character, not automatic suitability for every architectural style. Confirm current dimensions, packaging, colors, accessories, and availability when the material is ordered.

Manufacturer Claims and Project Assumptions Are Different

Step 1: Define the Actual Project Goal

Homeowners often begin by asking which color they should choose. A more productive first question is why the exterior project is being considered.

• Is existing siding damaged or deteriorated?
• Does the home need a stronger architectural focal point?
• Is water entering around windows or roof intersections?
• Will the wall be opened for air-sealing or insulation work?
• Is the homeowner preparing to sell?
• Is maintenance reduction the primary objective?
• Is the project correcting an incomplete addition or previous remodel?

These goals may lead to different scopes. A decorative gable accent, complete recladding project, targeted repair, and energy retrofit should not be estimated as interchangeable jobs.

Step 2: Choose the Profile by Architectural Role

PEPA, formerly the Vinyl Siding Institute, publishes design resources showing how shakes, scallops, clapboards, trim, and other polymeric products can support different architectural traditions. These resources are helpful precedents, but they do not turn every profile into a universal match.

Step 3: Decide Between Whole-House and Accent Use

PEPA’s architectural guidance recognizes shake and shingle polymeric cladding for both whole-house and accent applications. The better choice depends on the home’s form.

Whole-house coverage may be appropriate when:

• The building benefits from a continuous shingle or shake identity.
• The form is simple enough to balance the added texture.
• One factory color works across every elevation.
• The budget accommodates specialty siding, trim, preparation, and access.

Accent use may be stronger when:

• A real gable, dormer, bay, or porch provides a natural boundary.
• Horizontal siding should remain the dominant profile.
• The accent is intended to establish one clear focal point.
• A smaller specialty area meets the design and budget goals.

Accent-only use is not necessarily cheaper per square foot. Small or elevated areas may require substantial cutting, staging, trim, and flashing relative to their size.

Step 4: Build a Color Palette Around Permanent Materials

Roofing, brick, stone, windows, and major doors are expensive to change. Treat them as part of the palette rather than background objects.

1. Identify the undertones in the roof and masonry.
2. Select a dominant body color that works with those fixed materials.
3. Choose an accent with enough contrast to be visible, but not enough to divide the house unnecessarily.
4. Select trim that frames the composition and connects the materials.
5. Reserve the strongest color for a limited focal point such as the entrance.
6. View physical samples in morning, midday, and late-afternoon light.

Gentek’s Color Clear Through® system is intended to coordinate exterior siding, soffit, fascia, trim, and rainware colors. Confirm exact product availability and compare real samples because different materials and textures can produce different sheen and perceived color.

Step 5: Inspect the Existing Wall

Before deciding whether Fairhaven Sound can be installed over existing cladding, identify what is present and evaluate its condition. New siding should not conceal unresolved decay, leaks, loose material, or an unsuitable fastening base.

• What type of siding is currently installed?
• Is the wall flat, secure, and structurally suitable?
• Is there evidence of water staining, rot, mold, or insects?
• How are the windows and doors currently flashed?
• Is the water-resistive barrier accessible and repairable?
• Will added wall thickness bury existing trim?
• Are hazardous materials potentially present?

The answer cannot be determined from the exterior photograph alone. Selective removal or other investigation may be required.

Step 6: Treat Siding as Cladding, Not the Drainage Plane

PEPA states that vinyl, insulated vinyl, and polypropylene siding must be installed over a water-resistive barrier intended to limit liquid-water intrusion into the wall assembly.

The project scope should address:

• Water-resistive-barrier installation or repair
• Window and door head, jamb, and sill flashing
• Roof-to-wall step flashing
• Kick-out flashing at lower roof terminations
• Masonry and horizontal material transitions
• Deck, porch, and attached-roof intersections
• Mounting blocks and utility penetrations

Visible caulk can be part of selected joints, but it is not a complete water-management strategy. The assembly should direct water down and out even when incidental water passes the exterior cladding.

Step 7: Follow Instructions Written for Polypropylene

PEPA describes polypropylene siding as similar to vinyl siding while specifically directing installers to follow manufacturer instructions and applicable codes. Generic practices learned on PVC vinyl siding should not replace the requirements for the exact Fairhaven Sound profile.

Installation review should include:

• Required substrate and sheathing
• Approved fastener type, length, and corrosion resistance
• Fastener placement and spacing
• Temperature-related positioning guidance
• Expansion and contraction allowances
• Starter and panel-lock engagement
• Joint arrangement and pattern control
• Clearances at roofs, masonry, grade, and horizontal surfaces
• Approved trim and termination details

Panels should be secure without being fastened so tightly that intended movement is restricted. Obtain the current installation documents rather than depending on memory or an unrelated siding manual.

Step 8: Separate Air Sealing, Insulation, and Siding

These improvements can be coordinated, but they perform different functions:

PEPA’s 2026 construction guide says polypropylene siding can be incorporated into wall systems using continuous insulation. That compatibility does not mean Fairhaven Sound itself supplies a stated insulation value. The wall’s claimed R-value must come from documented insulation components and a complete assembly design.

Step 9: Be Skeptical of Energy-Savings Promises

No responsible contractor should promise a specific utility-bill reduction from installing shakes or scallops alone. Energy results depend on:

• Existing wall insulation
• Air leakage
• Window and door performance
• Attic and foundation conditions
• Heating and cooling equipment
• Thermostat settings and occupant behavior
• Weather and utility rates

If energy performance is a central goal, consider a qualified home-energy assessment and obtain a written wall specification showing the proposed air-control, water-control, vapor-control, and thermal layers.

Step 10: Plan Maintenance Before Installation

Gentek and PEPA describe polymeric siding as low-maintenance, but low-maintenance does not mean inspection-free. Exterior conditions should be reviewed periodically and after significant storms.

Homeowners should watch for:

• Loose, cracked, or displaced panels
• Open or distorted transitions
• Water staining below roof intersections
• Blocked weeps or drainage paths
• Organic growth and accumulated dirt
• Heat damage near grills or other heat sources
• Damage from reflected sunlight
• Failed sealant at joints where sealant is specified

Use Gentek’s current product-specific care instructions. Do not assume that a pressure-washing recommendation for another cladding applies to Fairhaven Sound. Gentek’s published Fairhaven care material directs rinsing with a garden hose after its described cleaning process.

Should Fairhaven Sound Be Painted?

Fairhaven Sound is sold as finished-color polypropylene siding rather than unfinished wood. Gentek’s public product and warranty information does not provide homeowners with a general field-painting procedure.

Do not paint it based solely on a coating labeled for “vinyl.” Obtain written Gentek approval and product-specific preparation instructions before applying any coating. If the concern is dirt, physical damage, or suspected abnormal fading, document and investigate that condition before concealing it.

Understand the Warranty Without Overstating It

Gentek markets Fairhaven Sound with a lifetime limited transferable warranty and additional coverage summarized on its product page. The complete warranty certificate—not the brief marketing description—determines eligibility, coverage periods, exclusions, transfer terms, claim procedures, and remedies.

Keep:

• The original contract and final invoice
• Installation and completion dates
• Exact profile and color
• Installer contact information
• Permit and inspection records
• Before, during, and after photographs
• Product labels and remaining cartons
• Care instructions and warranty documents
• Records of any claim, repair, or transfer communication

A transferable limited warranty should not be advertised as unlimited coverage for every subsequent owner or every kind of damage. Review the exact warranty before installation and again before a property transfer.

Do Shakes and Scallops Increase Resale Value?

They may improve architectural definition, exterior condition, and buyer perception. They do not guarantee a particular sale-price increase or return on investment.

The 2025 Remodeling Impact Report from the National Association of REALTORS® and National Association of the Remodeling Industry found that 46% of buyers were less willing to compromise on home condition. That supports the importance of a well-maintained property, but it does not establish a Fairhaven-specific resale percentage.

NAR also notes that cost recovery varies with design, material quality, location, age, condition, and homeowner preferences. Consult a local real estate professional or appraiser when resale is the primary reason for the project.

Check Permits and Historic-Property Requirements

The City of Davenport includes siding among projects addressed through its building and land-development process. It also warns that additional requirements may apply to properties in floodplains, on the Davenport Registry of Landmark Property, or on the National Register of Historic Places.

Requirements vary across Davenport, Bettendorf, Rock Island, Moline, and surrounding communities. Confirm the current rules with the authority responsible for the property before ordering material. Do not assume that a contractor’s familiarity with one Quad Cities municipality applies in another.

How to Compare Contractor Proposals

Require each bidder to price the same written scope. A meaningful proposal should identify:

• Exact Fairhaven Sound profile and factory color
• Installation areas shown on dated elevations
• Estimated quantities and waste assumptions
• Removal and disposal work
• Substrate inspection and preparation
• Water-resistive-barrier and flashing scope
• Named trim and accessory products
• Window, door, roofline, and masonry treatments
• Unit pricing for concealed damage
• Permit and inspection responsibility
• Project schedule and payment milestones
• Workmanship warranty and closeout documents

The lowest number may represent a genuinely efficient contractor, or it may omit necessary work. Compare exclusions and assumptions before comparing totals.

The Bottom Line

Gentek Fairhaven Sound shakes and scallops offer substantial design flexibility, but flexibility needs discipline. The profile should support the house, the color should coordinate with permanent materials, and every edge should have a planned transition.

Installation quality depends on the wall behind the siding as much as the surface visible from the street. Water management, flashing, fastening, movement, insulation integration, and documentation should all be addressed before the order is placed.

The strongest project is not necessarily the one with the most specialty siding. It is the one in which design, materials, installation, maintenance, and budget form one coherent decision.
