Can you still get Masonite siding?

No, you cannot still get original Masonite branded hardboard lap siding as it was discontinued in the late 1990s and early 2000s due to class-action lawsuits, but similar hardboard and engineered wood siding is still available from other brands. Masonite Corporation produced hardboard siding that was widely used in the 1980s and 1990s, but it developed serious problems with swelling, buckling, and rotting when exposed to moisture, leading to a major class-action lawsuit settled in 1998 for 1 billion dollars. After that, Masonite Corporation stopped manufacturing hardboard siding and focused on doors, which is now its main business. Today, Masonite International does not sell lap siding. However, you can still buy similar looking siding products that replace Masonite siding, such as LP SmartSide engineered wood siding, which looks like wood lap siding but is made from treated wood strands and is much more durable, James Hardie fiber cement siding, and generic hardboard panels sold at lumber yards for interior use, not exterior siding. Some salvage yards may have old Masonite siding boards for patch repairs, but new Masonite branded exterior lap siding is no longer manufactured or sold at Home Depot, Lowe's, or dealers. If you need to replace Masonite siding, you should use LP SmartSide or HardiePlank, which are modern, warrantied replacements that match dimensions.

No, you cannot still get original Masonite brand hardboard siding for exterior, as Masonite Corporation discontinued manufacturing of hardboard siding in 2001 after class action lawsuits due to moisture failure, though Masonite brand still exists for interior doors and hardboard panels, and similar hardboard siding may be available from other manufacturers under different names. Masonite siding was popular from 1980s to early 1990s as cheap wood alternative, made from wood fibers pressed with resin, but prone to swelling, buckling, and rot when moisture penetrated, leading to major class action lawsuits in 1990s with settlement of hundreds of millions, causing Masonite Corporation to stop producing exterior hardboard siding in 2001, shifting focus to interior doors, where Masonite is now largest interior door manufacturer in world, and to hardboard panels for interior use. Original Masonite siding brand is no longer manufactured or sold at Home Depot or Lowe's for exterior, you cannot buy new Masonite lap siding with that brand name for exterior house siding. However, similar products exist, generic hardboard siding from other companies may still be available in some regions, and engineered wood siding like LP SmartSide is considered modern replacement that looks similar but has better moisture resistance with wax and zinc borate treatment. If you need to patch existing Masonite siding on house, you may find salvaged boards or use LP SmartSide as replacement that can be trimmed to match. So you cannot get original Masonite brand exterior siding new, it was discontinued in 2001, but Masonite brand still sells interior hardboard and doors, and similar engineered wood siding like LP SmartSide is available as replacement.
