What Custom Plus Vinyl Siding Offers and How It Compares

Custom Plus vinyl siding is a mid-range product line that sits between basic vinyl and premium options

Custom Plus is a specific brand and grade of vinyl siding, not a generic category. It's manufactured by Ply Gem, one of the largest siding producers in North America, and occupies the middle tier of their lineup. The product comes in standard widths and profiles, with a thicker gauge than entry-level vinyl but less customization than their highest-end lines. If you're comparing quotes from contractors, you'll see Custom Plus named alongside other specific products like Certainteed, Mastic, or Alside — each with their own thickness, color range, and warranty terms.

The appeal of Custom Plus is straightforward: it costs less than premium vinyl while offering better durability than the cheapest options. Most homeowners choose it when they want a reliable, middle-ground product without paying for features they won't use. The siding comes pre-finished in a range of colors, so you won't need to paint it, and the material itself resists fading, cracking, and warping better than wood or aluminum.

Key Takeaways

• Custom Plus is a mid-tier vinyl siding line made by Ply Gem, thicker than basic vinyl but less customizable than premium grades.
• The product comes in standard profiles and colors, requires no painting, and typically carries a 20- to 30-year warranty depending on the specific product line.
• Installation cost and labor make up a large portion of the total project expense, so getting multiple contractor quotes matters more than the siding brand alone.
• Custom Plus works well for full home replacement or partial repairs, though mixing it with existing siding of a different brand can create visible color or texture differences.

Thickness, color options, and what comes in the box

Custom Plus vinyl typically measures 0.042 to 0.046 inches thick, which is thicker than basic vinyl (often 0.035 inches) but thinner than some premium lines. That extra thickness makes it more resistant to denting from impact and less likely to warp in extreme heat. The material is hollow inside, like most vinyl siding, with reinforcing ribs molded into the back to add strength without adding weight.

Color selection for Custom Plus runs between 15 and 25 standard options depending on which Ply Gem series you're looking at — whites, grays, tans, and earth tones are typical. The colors are baked into the vinyl during manufacturing, so they don't fade as quickly as painted surfaces. Ply Gem also offers some Custom Plus lines with wood-grain textures that mimic cedar or oak shakes, though these cost slightly more than smooth finishes. You cannot order custom colors or special requests; you choose from what's in the catalog.

Each order includes the siding panels themselves, plus J-channel trim for corners and edges, starter strip for the bottom course, and closure strips to seal gaps. You'll need to order flashing separately for windows and doors, and your contractor will advise on how much trim and closure material the job requires based on your home's dimensions.

Warranty coverage and what it actually protects

Custom Plus typically comes with a 20- to 30-year limited warranty, though the exact terms depend on which specific product line you choose and whether you register it. The warranty covers manufacturing defects — things like cracking, splitting, or color fading beyond normal weathering — but does not cover installation errors, storm damage, or wear from improper maintenance. If a panel fails under warranty, Ply Gem will replace the defective material, though you pay for labor and removal of the old panel.

The warranty is transferable to a second owner if you sell your home, which can be a selling point. However, the coverage period starts from the date of manufacture, not the date of installation, so if siding sits in a warehouse for a year before going on your house, that year counts against the warranty term. Ask your contractor when the material was manufactured and whether they can provide documentation.

Installation requirements and labor costs

Custom Plus vinyl siding installs the same way as any vinyl product: panels are nailed horizontally from bottom to top, with each course overlapping the one below it. The nails go through a slot in the top of each panel, allowing the vinyl to expand and contract with temperature changes. If nails are driven too tight, the siding buckles; if too loose, it rattles and can blow off in wind. This is why contractor experience matters more than the siding brand itself.

Installation typically requires removing old siding, repairing any damaged sheathing underneath, installing new flashing and trim, and then hanging the new panels. On a 2,000-square-foot home, labor usually takes one to two weeks depending on weather and the condition of the existing structure. Labor costs vary widely by region and contractor, but generally run $3 to $8 per square foot in South Carolina, on top of material costs. Getting three to five quotes from licensed contractors will show you the range in your area.

How Custom Plus compares to other vinyl grades

Basic vinyl siding costs less upfront but is thinner, more prone to denting, and may fade faster. Premium vinyl lines from Ply Gem and other manufacturers offer thicker gauges, more color options, and sometimes wood-grain textures that look more realistic, but cost 20 to 40 percent more. Fiber cement siding (like Hardie) costs more than Custom Plus, requires painting, and is heavier to install, but lasts longer and resists impact better. Aluminum siding is rare in new installations but still appears on older homes; it dents easily and conducts heat and cold, making it less energy-efficient than vinyl.

For most South Carolina homeowners, Custom Plus sits in the practical middle: better than the cheapest option, less expensive than premium, and sufficient for a 20- to 30-year lifespan if installed correctly and maintained. If your budget is tight, basic vinyl works; if you want the best appearance and longest life, premium vinyl or fiber cement makes sense. Custom Plus is the choice when you want reliable performance without overpaying for features you won't notice.

Maintenance and long-term care

Vinyl siding requires minimal maintenance compared to wood or aluminum. Wash it every two to three years with a soft brush and mild detergent to remove dirt, mold, and pollen. Avoid pressure washers on high settings, which can force water behind the panels and damage the sheathing underneath. Check that all trim and flashing remain sealed, and caulk any gaps that open up over time.

Custom Plus vinyl won't rot, rust, or need repainting, which is the main advantage over wood or metal. However, it can become brittle in extreme cold and may warp if exposed to intense direct heat for long periods. In South Carolina's humid climate, mold and mildew can grow on the surface, especially on north-facing walls that stay damp. Regular cleaning prevents this, and the vinyl itself won't be damaged by mold — only the appearance is affected.

Mixing Custom Plus with existing siding

If you're replacing only part of your home's siding — perhaps one wall or a section damaged by a storm — matching the existing siding can be difficult. Even if the original siding was Custom Plus, color variations occur between manufacturing batches and years. Vinyl also fades over time, so new panels will look brighter than 10-year-old panels next to them. Your contractor can try to match the color code, but a perfect match is unlikely.

The best approach is to replace a full side or the entire home at once, or to accept that a partial repair will show a color difference until the new siding weathers to match. Some homeowners use this as an opportunity to upgrade to a different color across the whole house. If partial replacement is necessary, ask your contractor to show you samples of both the old and new siding in daylight before ordering.

Frequently Asked Questions

How long does Custom Plus vinyl siding last?

Most Custom Plus products are warranted for 20 to 30 years, and many last longer with proper installation and maintenance. The actual lifespan depends on climate, sun exposure, and how well the siding was installed. In South Carolina's humid environment, regular cleaning helps extend the life by preventing mold and mildew buildup.

Can I paint Custom Plus vinyl siding?

Yes, but it's not recommended. Vinyl is designed to be left unpainted, and paint can trap heat and cause the material to warp or buckle. If you do paint, use a paint formulated for vinyl and expect to repaint every five to seven years. It's usually cheaper to replace the siding with a color you like than to paint and maintain it.

Does Custom Plus vinyl need underlayment or house wrap?

House wrap or felt underlayment goes under the siding to provide a water barrier and air seal. This is standard practice and protects the sheathing and framing from moisture. Your contractor should include this in the installation; if they don't mention it, ask why and get it in writing.

What's the difference between Custom Plus and Ply Gem's other vinyl lines?

Ply Gem makes several vinyl lines at different price points. Custom Plus is mid-tier — thicker and more durable than basic vinyl but less expensive and less customizable than their premium lines. The exact differences vary by specific product, so ask your contractor to show you samples and explain what you're paying for at each level.

Will Custom Plus siding increase my home's resale value?

New siding improves curb appeal and can help your home sell, but it typically doesn't return its full cost in resale value. Most homeowners recover 70 to 80 percent of siding replacement costs. The main benefit is that new siding removes a maintenance burden and signals to buyers that the exterior is sound.
