What are sistering floor joists? They're basically a set of beams made of wood that support the underside of a building's walls. Many homes in the U.S. and other countries use these as an integral part of their construction, and some even have them pre-built. However, there are many who'd prefer to build these themselves, as they provide a more custom look and feel to a home.
The way these come into play is pretty easy to understand. For starters, they're the foundation of the floor. And when they're not holding up the concrete or wood that supports your entire floor, then they're in trouble. If your siding isn't in top condition, it can crack, split, warp, and buckle under the weight of heavy trucks and cars driving by, and this means that your whole home could suffer from the negative effects of dampness and humidity. These issues can also lead to mold growth and other health problems in your home.
Because of these issues, you need to repair or replace your floor joists if you want to keep your house or home in good shape. But what if you don't know how to make these repairs? You might think that you'd need to hire someone else to do it, but today's DIY home improvement methods make it so that you can perform the task yourself. You'll also find that you save a lot of money in the process. It just makes sense all around.
According to extremehowto.com, people often choose to use plastics or engineered wood fibers for the joists since wood is a very porous material. As such, the floorboards will slowly warp and degrade over time if you avoid using wood for the beams. This is why many builders choose to use steel instead.
The problem with using hardwoods for the floorboards is that they're very heavy and usually have to be placed above other structural elements, such as ceiling and wall frames. This makes them prone to damage if something is dropped on them, which is why many homeowners prefer to use the lighter and less expensive plastic or fiberglass materials for their floor joists. What are sistering floor joists? They're basically four wooden beams that are placed directly beneath the floorboards. Since these beams support the floor, they need to be placed securely in place and they can't be easily pulled out of place, which makes them safer than their hardwood counterparts.
What are they used for exactly? They're often placed under the floors where heavier objects aren't wanted to sit or stand on the floorboards. For example, if you have a piano or other high piano cabinet, you may want to avoid placing heavy music equipment on the floorboards. If you do want to place heavy pieces, you can use the smaller, lighter sistering floor joists beneath them. They'll also allow you to use the smaller beams for delicate items, such as vases and small tables. They're ideal for use in high traffic areas where damage is more likely to occur, such as hallways or closets.
Joining floorboards with floor joists isn't just about safety though. While they help prevent damage to the floor, they also help keep sound out of a room. What's more, they allow you to change the floorboard configuration easily should you want to switch up the look or the arrangement. You can also adjust the height of the floor joists to accommodate different levels of ceiling height.
If you've ever had to replace floor boards because of damage or warping, you know exactly how frustrating this can be. But when you add the hassle and cost of installing new floors to an already difficult project, you can see why it's easier and cheaper to install the old ones with new floor joists. They provide strength and stability to weak floorboards, allowing you to avoid a lot of costly repairs or replacement. And once you've used them and know what a time saver they are, you may decide to invest in even more of them!
