Complete Guide to Gentek Fairhaven Sound Single Select
Why contractors prefer to sell and install this premium shake-and-scallop siding—and how thoughtful HOVER presentations can help turn small accent upgrades into larger, more complete exterior contracts.
Homeowners often know when an exterior looks special, even if they cannot immediately explain why. In many cases, the difference comes from texture, shadow lines and carefully placed architectural accents.
Gentek Fairhaven Sound Single Select is designed to provide the character of traditional cedar shakes and scallops with the lower-maintenance qualities of high-performance polymer siding. Contractors can use it across an entire elevation or, more commonly, as a premium accent on gables, dormers, entryways and other prominent architectural areas.
The strongest Fairhaven presentation is not simply, “Would you like to add shakes?” It is a visual conversation about proportion, color, texture and how the entire home can feel more finished.
What Is Gentek Fairhaven?
Fairhaven Sound Single Select is Gentek’s ultra-premium collection of polymer shakes and scallops. It is intended to recreate the warmth and individual character of traditional specialty siding without the routine scraping, staining or painting associated with natural wood.
Natural-Looking Character
Varied molds and cedargrain detailing help break up repetition and create a more handcrafted appearance.
Longer Panel Design
Gentek identifies an extended panel length of approximately 6 feet, 8 inches, helping installers create longer visual lines with fewer panel-to-panel transitions.
Integrated Locking System
The panel-locking design helps secure adjoining components and supports a more uniform finished appearance when installed correctly.
Installation Guides
Self-aligning nail slots and a temperature chart on the side tab help installers position the panels for seasonal movement.
Why Contractors Prefer to Sell Fairhaven
Fairhaven gives contractors a premium upgrade that homeowners can immediately see. That makes it easier to explain than an improvement hidden behind the wall or buried inside a technical specification.
- It creates a visible design upgrade. Texture on a gable, dormer or front entry can change the character of the entire elevation.
- It supports premium project positioning. Contractors can move the conversation beyond price per square and toward architectural value.
- It works with multiple home styles. Shake and scallop details can complement Craftsman, Cape Cod, cottage, Victorian and many updated traditional designs.
- It opens the door to coordinated upgrades. Once the homeowner sees an improved elevation, conversations about trim, soffit, fascia, gutters, windows and entry details become more natural.
- It tells a better before-and-after story. The improvement is easy to demonstrate in photographs, renderings, proposals and completed-project marketing.
Why Installers Prefer a Panelized Shake System
Compared with installing and finishing individual natural-wood shakes, a panelized polymer system can provide more consistent courses and a more repeatable installation process. Fairhaven also eliminates field painting and staining.
That does not mean installers should treat Fairhaven like conventional horizontal vinyl siding. Fairhaven is a polypropylene specialty-cladding system with product-specific fastening, temperature and layout requirements.
The installer’s practical rule
Use VSI guidance to understand the principles of polymeric siding, but use the current Gentek instructions for the actual Fairhaven panel. Product-specific requirements should never be replaced by habits carried over from ordinary lap siding.
Installation Details That Protect the Finished Result
-
1. Begin with a flat, code-compliant substrate
Specialty panels can reveal an uneven wall. Confirm sheathing, water-resistive barrier, flashing and substrate requirements before setting the first course.
-
2. Establish a level starting line
A small error at the starter course can become much more noticeable across a gable or prominent front elevation. Check level at multiple points instead of relying on an existing wall or roofline.
-
3. Follow the Fairhaven temperature chart
Polymer cladding expands and contracts as temperatures change. Use the temperature-positioning guidance molded into the panel and follow the current Gentek installation specifications.
-
4. Fasten through the designated nail slots
Use approved corrosion-resistant fasteners, maintain the required spacing and avoid driving fasteners so tightly that the panels cannot move as designed.
-
5. Respect panel engagement and course alignment
Confirm that every panel is completely engaged with the locking system before fastening the next course. Do not stretch, force or distort a panel to make it reach a layout mark.
-
6. Detail transitions before production begins
Plan how Fairhaven will terminate against lap siding, windows, doors, rooflines, inside corners and outside corners. Proper flashing must manage water behind the cladding; caulk should not be expected to replace correctly integrated flashing.
VSI, ASTM and Manufacturer Requirements
Specifications matter because the installation affects appearance, wind-load performance and warranty eligibility. Contractors should keep the current product literature, installation instructions and applicable code documents in the job file.
VSI guidance
The VSI installation manual explains general polymeric-cladding principles. It specifically directs installers of polypropylene siding to follow the manufacturer’s instructions and applicable local building codes.
ASTM D7254-21
This is the active ASTM specification addressing polypropylene siding. It is more directly relevant to Fairhaven than ASTM D3679, which applies to rigid PVC siding.
ASTM D5206-24
This test method addresses the wind-load resistance of rigid plastic siding when the siding is fastened according to the applicable product specification or manufacturer instructions.
ASTM D7856-21
This specification addresses color and appearance retention for solid and variegated plastic siding products using the CIELAB color space.
Gentek specifications
Gentek’s current instructions control panel positioning, fastening, allowable substrates, clearances, accessories and other requirements unique to Fairhaven. Verify the current version before installation.
How to Use HOVER to Win Larger Contracts
HOVER can turn photographs of a home into a measured, customizable 3D model. That gives contractors an opportunity to show homeowners where Fairhaven will create the greatest visual impact before materials are ordered.
Capture and measure the complete exterior
Include every elevation, opening, gable and transition. Review the completed measurements and confirm critical dimensions in the field before ordering.
Build a clean base design
Begin by showing the homeowner the primary lap-siding option without specialty accents. This establishes a fair baseline for comparison.
Add Fairhaven where architecture supports it
Test Fairhaven on front-facing gables, dormers, porch peaks, entry towers or other natural focal points. Avoid placing accents everywhere simply to increase the project total.
Present good, better and best options
- Good: primary siding replacement with essential trim.
- Better: primary siding plus a Fairhaven front-gable accent.
- Best: a coordinated exterior with Fairhaven accents, upgraded trim, soffit, fascia and other appropriate exterior components.
Connect the design to a transparent estimate
Show the added material, labor and trim costs as clearly labeled options. Homeowners should understand exactly what changes between each version of the proposal.
Important HOVER Presentation Note
Confirm whether the exact Fairhaven profile and color are available in your current HOVER material catalog. If they are not, use the closest appropriate visual representation, clearly identify it as conceptual and make final selections with current Gentek literature and physical product samples.
A rendering helps a homeowner make a confident design decision, but it is not a substitute for field verification, a product sample or the written contract.
A Soft, Professional Way to Present the Upgrade
“The standard design already gives you a clean exterior. I also prepared an option with Fairhaven on the front gable so you can see what a little more texture does for the home. It is completely optional, but the 3D model makes it easier to decide whether the architectural difference is worth the added investment.”
This approach does not pressure the homeowner. It gives them a clear comparison and allows the design to demonstrate the value.
Contractor Training Perspective
Sell the Design—Then Protect It with the Installation
A useful principle reinforced through experienced industry training is that premium siding must be supported by premium workmanship. A beautiful HOVER presentation may help earn the contract, but careful layout, fastening, flashing and temperature positioning are what protect the homeowner’s investment.
