If your home was built in the 90s, specifically in the years 1990-1996, chances are you have LP Inner-Seal Siding. To be sure, you can take a close look at your siding and find an LP in the knot pattern. This means that if you inspect your existing siding and locate a knot on a panel, you’ll be able to trace a very subtle “L” and “P” in the knot’s lines.
From the mid-1970s through the late 1990s, polybutylene pipes were installed in 6-10 million US homes. They were inexpensive and easy to install--but homeowners and plumbing professionals have discovered one serious flaw: Over time, oxidation, and exposure to chlorine in the water supply causes the pipes to swell and crack, leading to widespread flood damage throughout the home, usually without any warning.
Many home inspectors will detect polybutylene plumbing lines, but they are not required to report this finding, and thus it may go unaddressed. Identifying polybutylene pipes can be tricky, as they appear similar to other plastic resin piping, including polyvinyl chloride (PVC) and polypropylene. Polybutylene pipes, which are sometimes used in conjunction with copper piping, are described as:
white or gray in color having a dull or matte finish approximately 1/2" to 1" in diameter often stamped with "PB2110"
Louisiana-Pacific was hit with a barrage of lawsuits in the 1990s over the alleged subpar performance of LP’s faux-cedar Inner-Seal siding. LP Inner-Seal siding was produced from 1985-1995.
Inner-Seal siding from LP came with a 25-year warranty. However, the siding frequently started to decay, fall apart, and change color. Homeowners complained that their siding was expanding, discoloring, cracking, and even fungus and mildew was growing on it.
If your home was built in the 1990’s or earlier, you should check to see if your home has LP siding. Step outside and inspect your siding from above. In a perfect world, there should be no gaps or fractures, but LP Inner-Seal siding will show symptoms of board fragmentation. Look for a web of cracks on the bottom lap edge of your home’s siding. Can you break off bits by brushing your thumb against the cracks? This is an indication that the OSB is starting to delaminate, which produces voids, pits, and fractures that trap moisture and result in swelling. Moisture and the development of mold or fungi are brought on by this fragmentation.

Louisiana-Pacific was hit with a barrage of lawsuits in the 1990s over the alleged subpar performance of LP’s faux-cedar Inner-Seal siding. LP Inner-Seal siding was produced from 1985-1995.
Inner-Seal siding was a composite wood product that was pressure-fit together. The boards of this siding were made of stacked, pressed sheets held together by adhesive. The lower lap edge of the siding would fracture, absorb water, and expand as the glue started to degrade over time. The siding became exposed to the outdoors as a result of the delamination. Homeowners found clusters of mushrooms sprouting from the panels’ undersides.
After Hurricane Andrew caused havoc in South Florida in 1992, the product’s fragility became immediately clear. The disintegration process was intensified and accelerated by the high winds that tore through the panels, exposing the underlying oriented strand board (OSB) to torrential rainfall. LP was the subject of more than 37,000 claims, which were ultimately settled for over $1 billion by the business. For its part, the business recovered during the ensuing ten years, despite the fact that LP made no admissions of guilt. LP “got the most money to the most people in the quickest amount of time,” according to the judge who oversaw the case.
Unfortunately, if your house still has LP Inner-Seal siding, you’ll have to pay for replacement costs. Homeowners are no longer permitted to submit a claim to the LP Settlement Administrators following the conclusion of the class action litigation in 2002.
Louisiana-Pacific (LP) still makes siding products. In 1997, Louisiana-Pacific (LP) redesigned its siding and introduced LP “SmartSide.” There have been no significant claims of any problems with this new siding product.
因为以前换水管的花销不是非常巨大，中招也都自己换了了事。
相为房主自己买单。
因为这个牵涉到污染邻居土地，身体健康，责任太大。也是大坑。
能产生black mold的房买来出租，我也认为是坑。只要牵涉别人安全和健康问题，在我眼中，都是大坑。
哈哈，我有类似问题。。厨房离主管比较远， 坡度小，容易堵油脂。不过对我不是问题，拧开来放条小电动蛇进去，几分钟的事。 现在孩子们都走了，吃的油脂少了，不堵了。。
