Moving into a new home is a great feeling of accomplishment. Fixer-uppers have been a trend in the real estate market for some time now, and for a great reason. Often minor cosmetic adjustments to homes can have a major impact. But what happens when you find a problem that isn’t so DIY-friendly? Discovering masonite siding, also known as "fiberboard" or "hardboard", may unearth more serious problems for an older home.
Masonite Siding 101:
Hardboard is an engineered wood product that is comparable to particle board. This product is made from compressed wood fibers so it does not have a grain like solid wood. However, a wood veneer may be formatted over the product so it appears to be solid. If you’re unsure if your siding is in fact masonite, check unfinished areas like the attic for manufacturer’s markings. Another way to tell that your home has Masonite is the way that it is deteriorating -- look for flakes, curls and swelling in damaged areas. Masonite is know for extensive use in various industries for its durability and flexibility. During the 1980s and 1990s this product was used as exterior siding for many new construction homes. It was widely used for its low cost compared to regular siding material.
Why It's Bad News:
As one could imagine, a product with fibers is easily susceptible to moisture damage. The compression process often leaves only one side of the product smooth which proves to be a greater risk for water issues. Over time, masonite swells and rots if continuously exposed to the elements. If properly installed and maintained, the life of the masonite may be extended. However, there are serious deterioration issues that will eventually occur. Buckling, rotting, softening, blistering and insect infestation can also wreak havoc on damaged masonite.
Fixing the Masonite Problem:
While it may seem easy to panic and immediately plan to rip the siding out, it is important to note not all masonite siding has a current problem. If the siding is not showing signs of damage and was properly installed, chances are there is not an issue. However, do not halt maintenance and regular care. Slight water damage may be slowed through caulk and paint. These items are part of ongoing maintenance necessary for masonite siding.
Plan to replace the material in the future and monitor the material for further deterioration. Small repairs can be made with a comparable fiber cement product that will match the style and look of the existing masonite siding -- this is best handled by a reputable contractor. Serious damage such as swelling or rolling should be addressed as soon as possible. Water damage always presents a formidable risk to the rest of the home. It is important to contact a professional contractor to adequately assess the damage. Each situation is unique with masonite and it will take a proper inspection to really understand the extent and price to correct the problem.
Regular maintenance and home check ups will mitigate major issues like water damage before they occur. Schedule regular visits with a contractor to ensure a safe home.
