Replacing Your Deck? Here's How Much You Should Expect to Pay (2024)

Decks allow for outdoor dining, relaxation, and entertainment. However, they also deteriorate over time due to wear and tear, so understanding the average costs of deck repair and replacement is crucial for homeowners.

The average cost to repair a deck is about $2,000, but this figure varies depending on the extent of the damage and the materials needed. Standard repair tasks include replacing damaged boards, reinforcing structural supports, and refinishing the surface. The cost to replace a deck is typically around $15,000. However, this price varies depending on the deck size, materials, labor, permits, inspection, scope of work, and geographical location.

Average Deck Repair Costs

Deck life spans typically range from 10 to 30 years, and the cost and quality of deck materials often correlate with the frequency of repairs. The average cost ranges from a few hundred to several thousand dollars, depending on the scope of work and the geographic location of the home.

Minor repairs—such as replacing broken nails, boards, or loose railings—might cost between $100 and $4,000. More extensive maintenance involving structural issues or replacing a significant portion of the deck escalates the cost. This wide range of potential expenses underscores the importance of understanding the average deck repair costs before committing to a contractor.

Average Deck Replacement Costs

“The average price for a new, professionally built deck is around $20,000-$25,000, but you can get a smaller wood deck for as low as $10,000, and some maintenance-free options such as composite or PVC decking could cost as much as $60,000 or more,” says Diego Machado, president at Charlotte Deck Builders. While the initial cost may seem high, investing in a new deck brings long-term benefits, such as a competitive advantage when it’s time to sell and an enhanced outdoor living space if you decide to stay for the long term.

Factors That Affect Deck Replacement Costs

Machado says that some factors influencing the deck replacement costs are, “First, the size. The bigger the deck, the more expensive it will be. The second is the type of material used. A 100 percent wood deck is cheaper, but it requires some maintenance like repainting and sometimes replacement,” he says.

While the geographical location of your house affects the labor and material costs, the physical location of the deck also impacts the cost. If it is difficult for laborers to work under specific temperature, time, or space limitations, they may pass on the cost to you. Additionally, unique lighting and railing features also increase prices. Hiring a professional increases the final price, but DIYing increases the amount of time and the risk burden for the homeowner.

DIY vs. Hiring a Professional

Hiring a professional can significantly affect the overall cost of deck repair or replacement. “A professionally built deck usually costs three times more than the materials for a DIY deck, but it’s really important to know your local building codes. Simple structural mistakes, such as joists and beam sizes, post-to-beam connections, or even the way you use screws and nails, are fundamental to the durability and integrity of the deck. Ignored mistakes could put your family at risk or cost even more to rebuild,” notes Machado.

So, while DIY repairs may seem cost-effective initially, they require time, skills, and tools. Replacing a few boards or applying fresh deck stain is manageable for DIY enthusiasts. However, for long-term safety, complex structural repairs or complete deck replacements are best left to professionals. Hiring a professional contractor can ensure the job has the right permits and is done correctly, albeit at a higher cost.

Tips and Strategies for Saving on Deck Replacement Costs

Several strategies can help you save money on a deck replacement.

• Consider cost-effective materials, like pressure-treated lumber or composite decking, over expensive premium hardwoods or imported materials.
• Reuse existing deck components. Framing or railing can sometimes be salvaged and reused to reduce material costs.
• Shop around. “If you intend to replace your deck fully. I would also advise that you shop around for companies who can provide this service. In doing this, you may be able to find a business who can source materials for cheaper or charge less for their time and labor,” advises Mike Falahee, president of Marygrove Awning Co.
• Obtain multiple quotes from different contractors to negotiate the best value for price. Falahee adds, “Keep an eye on the cost difference between certain materials. You should also maintain your deck yourself to prevent damage.”
• Keep the deck size small. Another cost-saving tip is to keep your deck size small. It may be hard to define precisely how much space you need, but consider the deck’s purpose. If it will be primarily used for lounging and grilling, you might not need as much space as if you plan to host regular outdoor family meals. Take time to consider reasonable sizes for your desired deck experiences and research different materials best suited for the job.

Tips for Prolonging the Life of Your Deck

Quarterly maintenance prevents minor issues from becoming major headaches. Promptly address any early warning signs of deterioration or weather damage to extend the life span of your deck and minimize repair expenses.

Additionally, avoid excessive weight loads, keep the deck surface clear of debris, and don’t lean heavy items on the support beams. Watch out for wood-eating bugs and any wobbling. Both jeopardize the structural integrity of your deck.

Do I Need to Replace My Deck?

If your deck is over two decades old or is in visibly poor shape, the best option might be to replace it rather than undertake cosmetic repairs. Signs that it’s time to replace your deck include significant termite damage, rotting, warping wood, mold, cracked or damaged support posts, loose railings, loose or bowing boards, and wobbly stairs.

Consult with a decking professional to help your family safely enjoy your deck for many years.
