Old Decking Removal – Deck Dismantling DIY Guide

Removing an old deck may seem like a tough job, but with the right approach, tools, and techniques, it can be a manageable DIY project. Whether your decking is rotting, outdated, or you’re preparing for a new outdoor setup, this guide walks you through the entire removal process. From choosing the best tools to handling hidden challenges, this guide ensures you get the job done efficiently and safely.
Planning the Decking Removal
Before tearing into the deck, take some time to assess the structure and plan the process:
- Material Check – Is your deck made of wood, composite, or PVC? Each material requires different handling.
- Structural Integrity – Identify weakened or rotted sections that may collapse unexpectedly.
- Foundation Type – Determine if your deck is built on concrete footings, wooden posts, or attached to the house.
- Disposal Strategy – Plan where you will dispose of old decking boards, screws, and concrete footings. Recycling or repurposing some materials can save costs.
Having a clear plan prevents unnecessary damage and makes the process smoother.
Best Industry Tools for Deck Removal
Using the right tools is crucial for making the job efficient and safe. Here are some of the top industry-recommended tools for decking removal:
- Demolition Pry Bar (Gutster Demo Bar or Stanley FatMax Fubar) – The best tool for prying up boards with minimal effort.
- Reciprocating Saw (Milwaukee Sawzall or DeWalt 20V XR) – Essential for cutting through screws, nails, and stubborn connections.
- Cordless Impact Driver (Makita XDT16Z or DeWalt 20V Max XR) – Helps in removing deck screws and bolts quickly.
- Hammer and Nail Puller (Estwing or Stiletto) – Useful for extracting nails from old wood.
- Circular Saw (Bosch CSW41 or DeWalt DCS577X1) – Great for cutting large deck boards into manageable sections.
- Shovel (Fiskars or Bully Tools) – Required for digging out buried footings or posts.
- Jack or Lever Bar (AirShim or Crescent Bull Bar) – Helps lift heavy boards without excessive strain.
- Angle Grinder with Cutting Wheel (Metabo or Makita GA4530R) – Ideal for cutting through rusted bolts and screws.
- Heavy-Duty Work Gloves (Mechanix or Ironclad) – Protects hands from splinters, nails, and sharp edges.
- Safety Gear (3M Respirator, Safety Glasses, and Steel-Toe Boots) – Deck removal creates dust and debris, so protection is necessary.
With these tools, dismantling the deck will be much more efficient and less physically exhausting.
Step-by-Step Guide to Removing a Deck
1. Remove Railings and Balusters First
Start with the easiest components:
- Use a drill or impact driver to remove screws from railings.
- If nails were used, a pry bar and hammer will be needed to loosen the balusters.
- Be cautious when removing glass or metal balusters—set them aside safely.
2. Take Up the Deck Boards
Once the railings are gone, it’s time to lift the deck boards:
- Screwed-down boards – Use an impact driver to remove screws. If they are rusted or stripped, an angle grinder can cut through them.
- Nailed-down boards – A demolition pry bar or claw hammer will be needed to pry up each board.
- Rotten boards – If wood is deteriorated, cutting it into sections with a circular saw may be the easiest way to remove it.
3. Cut and Remove Joists
The joists are the horizontal support beams beneath the decking boards. Once the top boards are removed:
- Use a reciprocating saw to cut through any nails or screws securing the joists.
- Remove bolts or brackets using a wrench.
- Carefully lower each joist to the ground.
4. Take Out the Support Posts and Footings
Support posts and footings hold up the entire deck structure.
- Wooden Posts – If they are above ground, they can be removed by cutting them at the base with a reciprocating saw.
- Concrete Footings – These are the toughest to remove. Options include:
- Breaking them with a sledgehammer – Best for smaller footings.
- Digging around them and pulling them out with leverage – Works if they are not too deep.
- Using a jackhammer – Needed for deeply embedded concrete blocks.
If the deck was attached to the house, remove any ledger board (horizontal beam secured to the home) with a pry bar and impact driver.
Disposing of Old Decking Materials
Proper disposal is important to keep your site clean and environmentally friendly. Consider the following options:
- Reuse or Repurpose – Old deck boards can be used for firewood, DIY projects, or rustic furniture.
- Sell or Donate – If the wood is still in decent condition, sell it online or donate it to a salvage yard.
- Recycling Centers – Some locations accept treated wood for reuse or proper disposal.
- Hire a Waste Removal Service – If you have a large volume of waste, hiring a company that specializes in deck removal disposal can save time.
Common Challenges and Solutions
Even with the best tools, deck removal can have some challenges. Here’s how to handle them:
1. Stripped Screws or Rusted Nails
- Use an impact driver with a screw extractor.
- If that fails, cut them off with an angle grinder.
2. Rotting or Splintering Wood
- Use a circular saw to cut rotted wood into sections for easier removal.
- Handle old wood carefully to avoid injury from splinters.
3. Stubborn Concrete Footings
- If a sledgehammer doesn’t work, a rented jackhammer will break the concrete faster.
- In extreme cases, a contractor with excavation equipment may be needed.
4. Hidden Wasp Nests or Pests
- Check for nests before starting, especially in warm weather.
- Use an insecticide or professional removal service if needed.
