When most families think about replacing their old deck, the excitement centers on the new design, colors, and features. What often gets overlooked is the first step: Tearing out the existing deck. Demolition may not sound exciting, but it can have a big impact on your project’s timeline, safety, and overall cost.
At Custom Built, we know families don’t always expect demolition to play such a major role in their deck replacement budget. Our team has decades of experience handling tear-outs safely and efficiently, and we’ve seen firsthand the problems that come with old structures, from hidden rot to improper flashing.
In this article, we’ll walk you through why old deck demolition matters, how it affects your replacement costs, and what you need to consider before deciding whether to DIY or hire professionals:
- DIY vs. Professional Demolition
- Size and Complexity of Your Deck
- Material Variety Impact
- Structural Connections and Code Requirements
- Disposal and Hauling Costs
- Safety Risks of Old Decks
1. DIY vs. Professional Demolition
Some homeowners wonder if they can save money by tearing out their old deck themselves. On paper, the numbers might look appealing: Professional demolition typically runs $1,000–$2,000. But the reality is more complicated.
Professionals do this work every day. They have the tools, the team, and the process down. What might take a weekend crew hours to cut apart, load, and haul off, a professional team can do in a fraction of the time.
For a homeowner, the cost of DIY deck-building isn’t zero. You’re spending weekends wrestling with boards, paying for dumpsters, and possibly risking injury. Throwing out your back or stepping on a nail can turn that “savings” into weeks of lost time and medical costs.
2. Size and Complexity of Your Deck
The bigger and more complex your old deck, the higher the demolition cost. Multi-tiered decks, second-story structures, and decks built on sloped terrain require extra safety measures and more labor. Anytime crews work on ladders or elevated platforms, demolition slows down and costs increase.
3. Material Variety Impact
Whether your old deck is wood or composite, demolition pricing doesn’t change much. The main difference is weight.
Composite tends to be heavier, which can push disposal costs higher if you’re paying by the load. Concrete or paver patios under decks, however, add a different layer of difficulty. Removing heavy slabs or footings can be time-consuming and may require special equipment.
4. Structural Connections and Code Requirements
A major part of demolition isn’t just removing boards; it’s about how the deck connects to your home. Many older decks were built without proper flashing or water management at the ledger board.
If water has been sneaking into your home for years, the demolition phase is when the problem shows up. Responsible builders will always check these conditions and make sure the new deck is attached correctly and up to code.
This is why reputable deck builders rarely reuse existing structures. Reusing unsafe framing might save upfront, but it risks long-term structural failure.
5. Disposal and Hauling Costs
Every deck tear-out creates a pile of waste, and that debris has to go somewhere. Dumping fees are unavoidable, and they’re based on weight and volume. Someone has to haul the material, drive it to the waste yard, and pay the disposal fee.
While a homeowner might think about burning the wood, that’s not a realistic or safe solution. Professional demolition ensures debris is removed safely and legally.
6. Safety Risks of Old Decks
Finally, safety is a hidden but important cost factor. Demolition work comes with risks: sharp nails, heavy beams, circular saws, and unpredictable structural failures.
Professionals know how to dismantle decks without putting themselves or your home at risk. Cutting corners here can lead to expensive or dangerous outcomes.
What You Can Do to Prepare for a Deck Demolition
Getting ready for a deck demolition isn’t just the contractor’s job. You can play an important role in making the process smoother, safer, and faster. Here are a few practical steps to take before work begins:
- Clear the Deck: Remove all furniture, planters, grills, or décor. This ensures the demolition crew can work efficiently without delays.
- Protect Landscaping: If you have nearby plants, gardens, or trees you want to preserve, consider covering them with tarps or marking areas for your contractor to avoid.
- Plan for Pets and Kids: Demolition zones can be unsafe. Arrange for pets and young children to stay inside or off-site during work hours.
- Check Access Points: Make sure the crew has a clear path to bring in tools and haul away debris. Move vehicles, bikes, or other obstacles out of the way.
- Discuss Utilities: If lighting, electrical outlets, or gas lines run to your deck, work with your contractor to ensure they are safely disconnected before demolition.
Taking these steps not only makes the demolition more efficient but also helps reduce risks and unexpected costs.
