| Wood | $40–$60 |
| Metal | $55–$85 |

When to Repair vs. Replace Your Deck
While it’s a great idea to repair rather than replace a deck when possible, there are some instances when it’s better to start fresh. Unfortunately, if your deck is in poor shape, your best option is to tear it down and rebuild. Here are some key signs that it’s time to budget for deck replacement costs.
| Deck Repair | Deck Replacement |
|---|---|
| Minor damage, like small cracks | Significant damage, like large holes and split boards |
| Mold that hasn’t permeated the interior | Extensive termite or mold damage |
| Popped nails or screws | Large sections of rotting wood |
| Buildup of dirt and grime | The overall structure sways |
| Loose railing | Frequent and high repair costs |
| It needs a maintenance visit | It’s older than the projected lifespan |
Deck Repair Pro Costs
While you may be able to nail in a loose board or replace a missing screw on your own, most deck repairs are best left to the pros. Hire a deck repair expert in Denver, CO, to fix your deck as quickly as possible so that you can get back to enjoying your outdoor space before winter comes.
Labor
Labor rates for deck repairs in Denver start at $15 per square foot, or you may be charged $50 to $100 per hour. Most deck repairs take two to five hours, although rebuilding parts of the deck could take at least a couple of weeks when factoring in the permit process.
Permits
Smaller repairs won’t require a permit in Denver, but rebuilding parts of the deck or replacing the deck entirely does require a permit. Your contractor will know whether you need a permit and can handle the application and inspection process for you.
If you do need a permit for your project, you’ll need to contact the Community Planning and Development office. Permit fees start at $20 for projects with a value up to $500.
Taxes
You (or your contractor) will pay sales and use taxes on construction materials for your deck repairs. Denver has a general sales and use tax of 5.15% and a 4.81% consumer’s use tax on construction materials. The city/state combined sales and use tax is 9.15%.
Your contractor will be responsible for paying the sales and use taxes on materials and will build those costs into the project quote.
Tipping
Tipping isn’t required or expected for deck repairs, but if pros are working on a hot summer day or in cold temperatures, a tip of 10% to 20% can show your appreciation.
Does Deck Repair Increase Home Value?
Decks are particularly attractive in Denver, where many homeowners appreciate more time spent outdoors. A deck in excellent condition can offer 70% to 80% of a return on your investment into building the deck, so keep up with regular deck maintenance and repairs to get the best ROI.
