Material comparison
LP SmartSide Trim & Siding looks like wood. In North Jersey weather, substrate matters more than the coating.
Many homeowners shortlist LP SmartSide Trim & Siding for rich color and grain. NJ Vinyl Siding installs James Hardie fiber cement and Alside Ascend composite instead. We do not install LP SmartSide engineered wood strand siding.

What LP SmartSide Trim & Siding is (and what James Hardie is)
LP SmartSide Trim & Siding is engineered wood siding from LP Building Solutions: wood strands bonded with resins and factory coatings. It can look excellent on paper and in showroom samples. James Hardie is fiber cement: cement, sand, and cellulose formed into planks and shingles. The field panel does not behave like wood when water gets behind the face.
Both target a painted-wood street view. The difference is what happens at cut edges, failed caulk, and freeze-thaw cycles on North Jersey walls that stay wet on shaded lots.
- LP SmartSide: engineered wood strand with factory primer or color coats
- James Hardie: fiber cement, field-primed or ColorPlus factory finish
- HardiePlank and HardieShingle: common HOA-approved profiles in Bergen County
- Neither product forgives bad flashing. Substrate still matters when moisture enters
Why moisture and freeze-thaw worry us on engineered wood
North Jersey gets repeated freeze-thaw, nor'easter wind, and long dry-out times on wooded Ridgewood and Wayne lots. LP SmartSide relies on factory treatment and site sealant at every cut. If water finds an opening at a window head, nail line, or end joint, you are not dealing with cement board. You are dealing with wood-based strands under a coating.
That is why NJ Vinyl Siding does not install LP SmartSide. We have seen too many exterior failures trace back to moisture behind the face panel. Fiber cement and color-through composite give us more confidence on walls we warranty.
- Factory coating protects the face, not hidden water behind panels
- Field cuts and penetrations need perfect sealant discipline every time
- Palisade-facing homes in Fort Lee and Edgewater take wind-driven rain
- Shaded north walls stay wet longer after storms and snow melt
What NJ Vinyl Siding installs instead
When a homeowner wants a premium wood look without vinyl texture, we steer to James Hardie fiber cement or Alside Ascend composite cladding. Hardie fits HOA boards that know HardiePlank and want non-combustible cement board. Ascend fits homeowners who want color-through composite without a repaint calendar.
Premium insulated vinyl remains the value lane when budget and speed matter. We bring physical samples for each path at your estimate.
- James Hardie: fiber cement on /services/james-hardie with fixed-price proposals
- Alside Ascend: Royal composite cladding on /ascend, no cement or wood strand core
- Premium vinyl: CertainTeed, Royal, and Prodigy lines when insulated lap fits
- Mixed elevations: Hardie or Ascend street face, vinyl or Ascend elsewhere
If another contractor quotes LP SmartSide Trim & Siding
LP SmartSide can look attractive on bid day: rich colors, thick shadow lines, competitive price. Ask how they seal every cut, who warranties moisture behind panels, and what happens at window and roof-wall flashing. Compare the same scope against our James Hardie or Ascend proposal on tear-off, wrap, and trim.
This guide is not a knock on LP SmartSide marketing. It is our contractor line: we do not install engineered wood strand products in this climate.
- Ask for cut-sealant method and inspection photos on similar jobs
- Match tear-off depth and sheathing repair allowances across bids
- Request manufacturer warranty and labor warranty in writing
- See our siding cost NJ guide for typical Hardie and vinyl ranges
HOA boards and the wood-look decision
Ridgewood, Tenafly, and Montclair boards often approve HardiePlank when they reject standard vinyl. You do not need LP SmartSide to pass architectural review. NJ Vinyl Siding prepares James Hardie and Ascend submittal packets with spec sheets and color chips.
See our HOA siding approval guide for timelines and what boards expect before you order materials.
- Hardie samples pass many boards that want dimensional lap or shake
- Ascend composite passes when boards want depth without fiber cement weight
- Submit stone, trim, and shutter colors in the same packet
- Do not order panels until written approval when covenants require it
