Some of the Products We Proudly Use
Installation Standards & Material Quality
We Stand Behind
Siding performance over a 20–30 year lifespan depends almost entirely on two things: material selection and installation quality. Apex Pro Siding & Wrap follows manufacturer installation specifications precisely for every product we install — this is required to maintain warranty coverage and it is the only way to ensure the product performs as rated. We do not cut corners on flashing, starter strips, J-channel, or house wrap integration, because those details are where moisture problems originate.
Every project begins with a documented pre-installation assessment of the existing wall assembly, sheathing condition, and flashing details. We identify rot, failed house wrap, or improper drainage planes before new siding goes on the wall — not after. At contract signing, customers receive a written scope of work, product specifications, and warranty documentation for every material being installed.
We source siding products from James Hardie, CertainTeed, Kaycan, LP SmartSide, and Ply Gem, and we maintain installer certification with James Hardie as a registered contractor. Fiber cement siding installed by a James Hardie Preferred Contractor carries a 30-year non-prorated product warranty plus a separate workmanship warranty — coverage that is not available through uncertified installers.
What Types of Siding Services Do We Offer?
We install double 4-inch, double 5-inch, board-and-batten, and Dutch lap vinyl profiles, and offer insulated vinyl siding panels with integrated foam backing that improves wall R-value by up to R-2.7.
Hardie Board and Fiber Cement Siding Installation
Fiber cement siding outperforms vinyl in fire resistance, impact resistance, and dimensional stability. James Hardie products are Class A fire rated and carry a 30-year non-prorated warranty.
We install clapboard, shiplap, board-and-batten, and tongue-and-groove wood profiles and prime all six sides of every board before installation.
We install steel and aluminum panel systems for commercial exteriors, agricultural buildings, and residential applications where fire resistance or longevity is the primary driver.
Partial siding repair is appropriate when damage is localized and full replacement is appropriate when moisture has compromised the sheathing. We assess both options honestly and document our recommendation in writing.
We work with commercial building owners and GCs on storefront re-siding, office and medical building exteriors, multi-family housing, and mixed-use developments.
What Types of Siding Problems Do We Fix?
Moisture Intrusion and Rot Behind Siding
Moisture damage is the leading cause of premature siding failure and the most expensive problem a homeowner can ignore. The EPA estimates that 98% of homes with basements experience some form of moisture intrusion, and improperly installed or failed siding is a primary pathway in above-grade wall assemblies. In Apex's climate — 48 inches of average annual rainfall with humid summers — water finds any gap at windows, doors, roof-wall intersections, and penetrations. We remove the failing siding, assess and replace rotted sheathing, install a new continuous weather-resistive barrier, and reinstall with proper flashing details.
Warped, Buckled, or Wavy Vinyl Siding
Vinyl siding expands and contracts with temperature — a 12-foot panel can move up to 5/8 of an inch between Apex's winter lows and summer highs. When panels are face-nailed too tight or installed without proper expansion gaps, they buckle and warp. This is an installation error, not a product defect. We replace buckled sections, correct the nailing pattern, and reinstall with manufacturer-specified expansion clearances.
Cracked, Chipped, or Impact-Damaged Siding
Hailstorms, falling tree limbs, and lawnmower debris cause localized siding damage that allows water infiltration at the breach point. Fiber cement and wood siding can crack along the grain under severe impact. We match existing siding profiles and colors for patch repairs, and we assess adjacent sections for hidden damage that may not be visible from the surface.
Failed Caulking and Sealant at Trim and Penetrations
Caulk at window and door trim, utility penetrations, and corner trim has a functional lifespan of 5–10 years in North Carolina's climate, shorter if it was applied over dirty or wet surfaces. When caulk fails, water runs behind trim boards and into the wall cavity silently. We strip and replace all failed sealant as part of every siding job and use only paintable, flexible polyurethane or siliconized latex products rated for exterior use.
Faded, Peeling, or Oxidized Siding Finish
Wood and engineered wood siding requires repainting on a 5–7 year cycle in humid southeastern climates. Fiber cement siding with a factory finish is baked and far more durable, but field-cut edges require priming and sealing at installation. We repair surface deterioration, prep the substrate correctly, and apply finish coats with commercial-grade exterior coatings rated for the material.
What Specialty Services Do We Offer?
House wrap is not an optional upgrade — it is a required component of a code-compliant wall assembly in North Carolina. The NC Residential Building Code requires a weather-resistive barrier on all exterior walls under siding. We install Tyvek HomeWrap, DuPont Flashing Tape, ZIP System sheathing panels, and Huber AdvanTech products depending on project requirements. ZIP System eliminates the need for separate house wrap on new construction by integrating the weather barrier and sheathing into a single panel — a system that reduces labor time and eliminates seam failures at the wall.
Continuous insulation installed over the sheathing before siding eliminates thermal bridging through wall studs, which account for 20–25% of above-grade heat loss in a typical wood-framed home. We install rigid foam CI systems — EPS, XPS, and polyiso boards — integrated with proper drainage mat and weather barrier for compliance with the NC Energy Conservation Code. Continuous insulation upgrades are most cost-effective when combined with a full re-siding project.
Apex's residential developments — from planned communities like Haddon Hall and Brighton Forest to the older neighborhoods near Salem Pond Park — contain a wide range of architectural styles and HOA-governed exterior color requirements. We assist homeowners in matching existing siding profiles and colors for partial repairs, navigating HOA approval processes, and selecting products with color options that hold up under direct southern sun exposure.

Siding & Wrap FAQs
How long does a full siding replacement take on a typical home in Apex?
A standard single-family home siding replacement in Apex runs 3–7 days for the installation crew, depending on square footage, the number of penetrations and architectural details, and whether sheathing repairs are required. We schedule a pre-construction walkthrough to review scope and access before confirming a start date. Most projects in the 1,500–2,500 sq ft range complete in 4–5 days under normal conditions.
Does siding installation in Apex require a permit?
Yes. The Town of Apex requires a building permit for full siding replacement. We pull the permit on your behalf as part of every project — it is included in the contract and there are no hidden permit fees. The permit triggers a final inspection by the Town of Apex Inspections Department, which confirms the installation meets NC Residential Building Code requirements including the weather-resistive barrier.
Does re-siding add to a home's resale value?
It does, and the return is well documented. The National Association of Realtors' Remodeling Impact Report puts vinyl siding replacement at approximately 80% cost recovery at resale, and fiber cement siding consistently ranks among the top exterior improvement projects for ROI. Beyond the dollar figure, updated siding directly affects buyer first impressions and the appraiser's condition rating — both of which influence sale price and time on market.
What is the difference between house wrap and a vapor barrier?
House wrap is a weather-resistive barrier — it blocks liquid water from entering the wall assembly while allowing water vapor to pass through and escape. A vapor barrier is a low-permeability membrane designed to block moisture vapor movement entirely and is typically installed on the interior warm side of the wall in cold climates. In North Carolina's mixed-humid climate, the NC Building Code does not require an interior vapor barrier in most residential applications — but it does require a weather-resistive barrier under all exterior siding. Installing a true vapor barrier on the exterior in this climate can trap moisture in the wall cavity and cause more damage than it prevents.
How do I know if my siding has hidden moisture damage?
The most reliable indicator is soft or spongy sheathing behind the siding, which you can sometimes detect by pressing firmly on the wall surface. Other signs include interior drywall staining or bubbling paint near windows and doors, visible mold or mildew on the siding surface, siding panels that have separated from the wall or shifted out of alignment, and a persistent musty odor inside exterior walls. The only way to confirm the extent of damage is to remove siding panels in suspect areas and inspect the sheathing and framing directly — which we do as part of every pre-installation assessment at no charge.
