Can Decking Run Perpendicular To House?

If you’re planning on installing decking, you might be wondering if you can run the boards perpendicular to your house. The answer is yes, you can!

There are a few things to keep in mind when installing decking boards perpendicular to your house, such as the size of the boards and the spacing between them.

With careful planning, you can create a beautiful and functional outdoor space that you and your family will enjoy for years to come.

When decking boards are installed across the joists at a right angle to the house, it eliminates the possibility for installation at a perpendicular angle. This means that if you want your decking boards to be installed perpendicular to the house, you’ll need to either install the joists at a 45-degree angle or use shorter boards and install them diagonally across the joists.

Second, both of these options will provide more stability for your deck and prevent cupping or warping of your decking boards over time. Keep in mind that installing the joists at a 45-degree angle will require more support than installing them parallel or perpendicular to the house. If you’re not sure which option is best for your situation, consult with a professional contractor who can help you determine which method will work best for your home.

There are many benefits to installing decking boards at a perpendicular angle to your home. This type of installation eliminates the possibility for cupping or warping of your boards over time and provides more stability for your deck. Additionally, it allows you to use shorter decking boards and install them diagonally across the joists, providing a different look for your deck. If you’re unsure about which option is best for you, consult with a professional before beginning your project.

Should deck boards be parallel or perpendicular to house?

The default direction for decking is parallel with the house. Some reasons for this are:

  • – structural support of the deck framing
  • – water runoff
  • – appearance

Decking running parallel to the house is beneficial structurally, aesthetically and cost wise. Structurally, it provides support for the deck framing. Aesthetically, it provides a clean look. Cost wise, it is less expensive to build a deck this way.

Which way should decking run from house?

As for which way the decking boards should run, it really depends on the look you’re going for. If you want a more traditional look, you can run the boards perpendicular to the house. If you’re going for a more modern look, you can run the boards parallel to the house.

There are pros and cons to both approaches.

Running the boards perpendicular to the house will give you more stability and support. It’s also easier to lay the boards this way since you won’t have to worry about making cuts at odd angles. The downside is that it can make your deck look a bit more formal and less inviting.

Running the boards parallel to the house can give your deck a more relaxed and informal look. It’s also a good option if you want to maximize your deck space. The downside is that you’ll have to make more cuts, and the deck may not be as stable.

Ultimately, it’s up to you to decide which way to run the boards. Consider the look you want to achieve and the amount of work you’re willing to put in. If you’re not sure, you can always ask a professional for advice.

Should there be a gap between decking and house?

There is no one-size-fits-all answer to this question since it largely depends on the style of your deck and the size of the gap. Typically, a gap of 1/2 to 3/4 inches is ideal. This allows rain and melted snow to easily flow through the decking and into the ground.

In some cases, a gap wider than 3/4 inches may be necessary. This is especially the case if your decking is made from composite materials, such as plastic or PVC. These materials are not as forgiving as traditional decking materials, and may require a wider gap to prevent water from entering the composite material and causing structural damage.

Ideally, you should consult with a qualified contractor to determine the correct width of gap for your specific situation. A gap that is too large can cause water to accumulate and rot the decking, while a gap that is too narrow can cause water to accumulate and rot the structural members of the house.

Does it matter which direction deck boards run?

When it comes to decks, there are a few key things to keep in mind. One of the most important things is the direction that the deck boards run. You always want to run the boards parallel to the length of the house for a few reasons. First, it gives the deck a much bigger look. Second, it helps to elongate the space and make it seem larger than it actually is. Finally, it provides a more uniform look overall.

Of course, there are always exceptions to the rule. If you have a particularly small deck or you’re working with an oddly shaped space, you may need to run the boards perpendicular to the house. In these cases, it’s still important to try and run the boards parallel to the longest length of the deck for the reasons mentioned above.

In general, it’s best to avoid running the boards perpendicular to the house unless absolutely necessary. If you do need to run the boards perpendicular, be sure to take the above factors into consideration to ensure that your deck looks its best.

What should you not do when building a deck?

When building a deck, there are a few things you should avoid doing in order to ensure the structure is safe and will last. One of the most important aspects of deck building is the planning stage. You need to take into account the size of your deck, the materials you will use, and if you need to get a permit. Once you have a plan, the next step is to build the foundation, or footers. The footers need to be the correct size and installed properly in order to support the deck.

If you use the wrong materials or fail to follow the manufacturer’s instructions, you run the risk of the deck not being up to code. This could lead to serious safety issues or even the deck collapsing. Another area where many people make mistakes is when they install the ledger board. The ledger board is what attaches the deck to your house. If it is not installed properly, it can cause the deck to pull away from the house and collapse.

Building a deck is a big project, but it is one that can be very rewarding. By taking the time to do things right, you can avoid making common mistakes that could lead to serious problems.


There’s no right or wrong answer when it comes to deciding whether to install your decking boards perpendicular or at a right angle to your house. It ultimately comes down to personal preference and what you think looks best.

If you’re going for a more traditional look, then installing the boards at a right angle to the house is probably your best bet. However, if you’re looking for something a bit more unique, then installing them perpendicular to the house could give you the look you’re going for.

Whichever way you decide to go, just make sure that you take the time to do it right and you’ll end up with a beautiful deck that you can enjoy for years to come.
