    What Is LP Siding?

    LP (Louisiana-Pacific) siding refers to a type of exterior board made by the Louisiana-Pacific Corporation. LP siding is a wood-based product that is often used for residential and commercial construction. The most well-known LP siding product is SmartSide, which is an engineered wood siding.

    SmartSide siding is composed of wood strands or fibers that are bonded together with resins, wax, and zinc borate for durability and resistance to termites and fungal decay. The strands are then treated with a water-resistant resin overlay, creating a product that mimics the look of traditional wood siding but with enhanced durability.

    LP SmartSide siding is now designed to be more durable and resistant to issues such as rot, decay, and insects compared to traditional wood siding. It is available in various styles and textures, providing homeowners with options to achieve the desired aesthetic for their homes.

    However, It’s important to note that there were some issues with early versions of Louisiana Pacific in the 1990s, particularly related to moisture absorption and subsequent damage. However, LP has since addressed these concerns and introduced improved formulations to enhance the performance of their siding products. As with any construction material, proper installation and maintenance are crucial for ensuring the longevity and performance of LP siding.

    How to identify LP "Louisiana Pacific" Siding?

    Lp Siding knot

    Identifying LP (Louisiana-Pacific) SmartSide siding can be done through visual inspection. Here are some general characteristics that may help you identify LP SmartSide siding:

    Wood Grain Texture:

     LP SmartSide siding typically has a wood grain texture that resembles traditional wood siding. The texture is often designed to mimic the appearance of natural wood.

    Imprinted Brand Name:

    Look for imprinted brand names or logos on the siding. LP SmartSide may have the manufacturer’s name, “LP,” or “SmartSide” imprinted on the back or edge of the board.

    Stamped Identification Codes:

    Some LP SmartSide products may have identification codes or stamps on the back that indicate the product type or manufacturing information. Check for any markings that might be present. See image below!

    Pre-Finished Options:

    LP SmartSide siding is often available in pre-finished colors or primed for painting. The product may have a factory-applied finish that can provide additional protection and aesthetics.

    Engineered Wood Appearance:

    LP SmartSide is engineered wood, and as such, it may have a more uniform appearance compared to natural wood. Look for signs of an engineered or manufactured product, such as consistent grain patterns.

    Sizing and Profile:

    LP SmartSide comes in various sizes and profiles. Check the dimensions and profile of the siding to see if it matches the specifications commonly associated with LP SmartSide products.

    If you are unsure about the LP on your property, you may also contact the builder, contractor, or the local building department to obtain information about the materials used in construction.

    It’s worth noting that LP SmartSide has gone through product improvements over the years, so the appearance and characteristics may vary based on the specific version or formulation of the product. If in doubt, you can refer to the manufacturer’s documentation or website for more detailed information about their siding products.

    Moisture And Mold Build-Up Are Common Issues with LP Siding

    LP SmartSide, is NOT known for it’s durability and resistance to moisture-related issues. When moisture infiltrates improperly installed or damaged LP siding, it can potentially lead to mold growth, compromising the structural integrity and aesthetic appeal of the siding. Homeowners should regularly inspect and address any water damage promptly, ensuring proper ventilation and drainage. Implementing preventive measures, such as sealing joints and edges, can further safeguard against moisture intrusion.

    When there is no moisture barrier or “Vapor Barrier”, any cracked caulking or openings in your LP, this can allow rain to penetrate and get trapped behind the siding, causing mold build-up and wood rot. Thanks to excessive moisture in the air during the rainy season, the trapped water behind the siding cannot evaporate and continues to wreak havoc on the wood behind your siding.

    Once dry rot and mold damage start eating away at the studs and sheeting, the siding must be replaced to avoid damage to the structural integrity of your home, which is an issue that you want to avoid at all costs.

    Carpenter Ants LOVE LP Siding

    If we had a nickel for every carpenter ant we have seen in LP siding, we would be rich here in Clark County WA! Rot and mold damage make the soft, moist wood behind your siding the perfect nesting material for carpenter ants. These ants can help accelerate structural damage to your home.

    LP Siding Has Been Involved in Nation-Wide Lawsuits

    There have been various lawsuits and legal issues associated with LP (Louisiana-Pacific) siding, particularly related to the earlier versions of their products. Many of these legal matters were related to allegations of product defects and failures that led to issues like water intrusion, rot, and other damages.

    However, the details of specific lawsuits can change over time. All LP Siding lawsuits are closed and Homeowners are no longer able to apply for a calim.

    If your home has LP Louisiana Pacific Siding, We recommend getting a replacement with James Hardie Fiber Cement Siding and fix any rot under the siding before it causes more damage.

    Choose this company for you siding, you won't be sorry! The owner Ian, is far and above best contractor I have ever worked with. Excels at communication, follow up and explains everything in a friendly non-pressure way. I interviewed three other contractors, before settling on Elite. I knew I would be in good hands for this huge investment with Ian as he was genuine and sincere about providing the best result. Both the siding and the paint crew are top notch professionals, with a great work ethic and attention to detail, they are Hardie trained so you can be sure the installation was done to the highest standard and it shows! We went from ugly worn out 20 year vinyl to James Hardie siding, and the difference astounding, very very happy with what feels like a new house now.

    Ian is extremely knowledgeable at his craft. He was so patient with all of our questions and concerns. We felt so comfortable from the moment we met him. We met with a few other companies to do our due diligence but Ian was the clear choice.

    My home has a fairly complex exterior, and we were looking to re-side the home as we were dealing with constant issues of water intrusion. I was searching the greater Portland/Vancouver area for Siding Contractors for Hardie Siding, as we really just wanted something that would hold up against the elements and protect us in the case of any nearby fires (we’re close to some woods). After meeting Ian from Elite Home Exteriors, we decided to go with him and we couldn’t have been happier that we decided to go with him as out Siding Contractor. We had additional problems from the water damage too, and the folks he recommended were also top notch. Ian and team are a James Hardie Elite Preferred Siding Contractor, which means basically that he’s passed the highest certification for installing James Hardie siding products. I would work with him again, but based on his fit and finish, I probably won’t need to! Thanks Ian!

    Working with Ian and his company was an absolute pleasure. I currently own 2 homes and have had 3 previous houses, so I’ve had experience with many contractors over the last 20 years and most are not good. My husband and I had a water intrusion issue (undisclosed to us during a house purchase) that we subsequently discovered for ourselves 6 months later in the rainy season. After meeting with many contactors to figure out how to execute the repair, we decided that their prices were outrageous even for just a patch job and we decided to do the right thing and replace all the wood siding with Hardie plank. My husband found Ian online, and we met with him. He is excellent at communication, through emails/text and/or phone calls. He was always pleasant to meet with and didn’t talk to me as if I was a dumb homeowner, which happens quite a bit in this industry. He was happy to answer all my questions and work with us on a documented design for adding architectural details so there was no questions on how the job would look. He and his crew were always punctual and professional. They finished the job ahead of schedule and did everything promised. Honestly, the water intrusion situation was very stressful, but Ian made it a pleasure to get resolved. I am so happy that we went with him and have had excellent results. My high-strung HOA was even happy about his work and gave us a compliment. I wholeheartedly recommend him, and I would be happy to talk to anyone wanting a reference about our pleasant experience. It isn’t every day that such a huge job is completed with such ease and professionalism. I 100% recommend working with Ian and Elite Home Exteriors NW – you won’t be disappointed!

    The South wall of the house had rot and cut siding from a previous connected wood deck. Ian was a pleasure to work with and a consummate professional from start to finish. He answered detailed questions, gave me several options to fit within my budget. Ian communicated with me throughout the process, and was accommodating when I requested more detail, or a change during planning phase. His crew shows up on schedule, were friendly and courteous of my property, and cleaned up thoroughly before leaving. The job was completed quickly and within budget. The new siding and paint is an asset to this house and exceeds my expectations. I enjoyed working with Ian, and would recommend Elite Home Exteriors NW to anyone considering a siding update for their home.

    Glad I hired Ian and his team to replace siding on the south-facing side of my house. Communication with Ian throughout project was as good as any contractor I've worked with. The work was done well, went smoothly, just what you want. Also glad to see them not show up in expensive vehicle wrapped graphics, etc that the customer pays for. I'll have more siding to do on my house and will hire them again.

      The History of LP Lousiana-Pacific Siding

      LP (Louisiana-Pacific) siding has a history marked by innovation, challenges, and evolution in the construction industry. Here’s an overview:

      1. Origins: Louisiana-Pacific Corporation, commonly known as LP, was founded in 1973 in Portland, Oregon. Initially, the company focused on producing oriented strand board (OSB), a type of engineered wood panel made from thin wood strands bonded together with adhesives.

      2. Introduction of LP Siding: In the late 1970s and early 1980s, LP expanded its product offerings to include exterior siding products made from OSB. LP siding was marketed as a cost-effective alternative to traditional wood siding, offering improved durability and weather resistance.

      3. Varieties: LP siding came in various styles and finishes, including lap siding, panel siding, and trim boards. It was designed to mimic the appearance of natural wood while providing the benefits of engineered wood, such as resistance to moisture, rot, and insects.

      4. Popularity: LP siding gained popularity among builders and homeowners for its affordability, ease of installation, and low maintenance requirements. It was widely used in residential construction projects across North America, particularly in regions where wood siding was prevalent.

      5. Challenges and Lawsuits: Despite its initial success, LP siding faced challenges related to product performance and durability. In the 1990s and early 2000s, the company became embroiled in lawsuits and class-action settlements alleging that some of its siding products were prone to premature deterioration, warping, and delamination due to manufacturing defects and improper installation.

      6. Product Revisions: In response to these challenges, LP made revisions to its siding products, including improvements in manufacturing processes and quality control measures. The company introduced new formulations and installation guidelines aimed at addressing the issues raised by consumers and contractors.

      7. Diversification and Innovation: Over the years, LP diversified its product portfolio to include a wide range of building materials and solutions beyond siding, including engineered wood products, decking, and roofing materials. The company continued to invest in research and development to innovate and improve its products’ performance and sustainability.

      8. Continued Market Presence: Despite the controversies and challenges it faced, LP siding remains a significant player in the exterior cladding market. Its products are still used in residential and commercial construction projects, with updated formulations and installation practices designed to enhance durability and longevity.

      Overall, the history of LP siding reflects the dynamic nature of the construction industry, characterized by innovation, challenges, and ongoing efforts to meet the evolving needs and expectations of builders and homeowners.
