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
In addition to the above costs, you’ll face a few more expenses when planning a deck repair project. Here’s what to expect.
Licensing
When repairing a deck in Washington, D.C., it’s important to hire a licensed, insured, and bonded Home Improvement Contractor for the job. Working with a qualified professional who builds decks will ensure your deck repair is safe and compliant with Washington, D.C.’s regulations.
Permits
Your deck repair pro in Washington, D.C., should pull any required permits for your repair project. In the nation’s capital, deck permit fees and structures depend on the value of the work performed. You’ll either pay a flat fee or a flat fee plus a percentage of the total construction cost.
Sales Tax
Don’t forget about Washington, D.C.’s 6% sales tax rate when budgeting for deck repairs. It might not make a huge difference in your overall costs—but if you need $1,000 worth of decking materials, for example, you’d pay $60 in sales tax.
Does Deck Repair Increase Home Value?
Fixing a damaged deck can enhance your home’s desirability in the eyes of potential buyers, which could help you sell your house for a higher price. Decks can be particularly appealing in densely populated places like Washington, D.C., since they provide private outdoor gathering spaces (which can be hard to come by).
According to the Journal of Light Construction (JLC) Cost Versus Value Report, homeowners in the Middle Atlantic region recoup 94.9% of the cost of adding a wood deck.
