Take a step in the right direction by learning about deck levels
If you’re new to the world of outdoor features, there are a few things to know before building a deck, including deck step down requirements. One of the main questions to answer: Should my deck be level with my home?
In a nutshell, the answer is—no. Your deck should never be level with your home due to the risk of water damage. If your deck or patio sits at the same height as your home, it’s easy for water to get inside and wreak havoc. We’re not just talking about puddles in your entryway, either. Let’s review patio door to deck transition requirements.
How Far Below My Patio Door Should My Deck Be?
You should install the decking a few inches below the patio and entry door threshold. Hiring a local deck builder ensures they will install the deck a minimum of 2 inches below the door, but no more than 4 inches is necessary. The reason? If your deck is level with your patio door, you invite all sorts of problems due to splashback from rainfall—think rot and other water damage.
Should There Be a Step Down to a Deck?
Yes, there should be a step down to a deck from your door. Ideally, the step should measure between 2 inches and 4 inches in height. There are benefits to adding a step down to your deck. For one, it will help keep out water and other debris. Adding a step down can help prevent water damage and dreaded water damage restoration expenses. If you decide not to build a step down to a deck, invest in water-resistant materials and waterproof seals to prevent water damage.
What Is The Best Patio Door-to-Deck Transition?
It might be tempting to keep your deck level with your home. But giving a little space—2 inches to 4 inches to be exact—between the threshold and the deck’s first step is the best transition. Knowledgeable deck builders strongly suggest having a step down built into the deck from your home’s entryway to prevent water from pooling or splashing at the entryway and getting inside your home. Over time, water damage can corrode the doorframe and impact a home’s foundation.
Should a Deck Have a Slope?
If your deck is attached to your home and its boards run parallel to the house, your deck should have a slope. It’s best if your deck has a slope of about ⅛ inch per foot to ensure that water flows away from your home.
Suppose your deck is attached to your house, and the boards run perpendicular to it. In that case, you don’t need a slope because the gaps between the deck boards should drain rainwater enough to keep it away from your home. If you have a floating deck that doesn’t touch your home, you don’t need a sloping deck because the direction of the water flow doesn’t affect your house.
Can I Build a Deck Directly on the Ground?
Yes, you can build a deck directly on the ground. Ground-level decks have varying benefits that attract homeowners looking to add a little ambiance to their backyard. This type of deck can be cost-effective and may not require additional construction for railings or stairs. But, before you start building, there are two main considerations to keep in mind before starting this project: local building codes and deck materials.
Local Building Codes
The last thing you want is the added headache of a building code violation. Research your area’s local building codes before breaking ground. This step will reveal what your local municipality considers a ground-level deck, any requirements (e.g., stairs or railings), whether or not you need a building permit and—most importantly—if you’re allowed to build one.
Building Materials
Direct contact with the ground can invite environmental stresses, as wood decays faster when in direct contact with the ground. Moisture impacts wood differently on the ground than in the air. If building a deck directly on the ground, seek out speciality-treated wood or composite building materials.
What Should Be Put Under Deck Stairs?
The space under deck stairs can be critical for preventing that area from becoming a field of weeds or worse—a moisture trap. (Too much moisture can speed up decay in wood.) Adding washed gravel or crushed stone to this area will create a natural runoff for rain and snow. Lay the gravel on top of landscape fabric to prevent weed growth. Layer the stones about 3 inches to 4 inches deep.You can also install an under-decking drainage system to avoid moisture damage, water build-up, and pesky critters.
