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
There are a few other costs to keep in mind when budgeting for deck repairs in Boston, including permits and sales tax. Here’s how those factors impact your final cost.
Licensing and Certification
It’s essential to hire a qualified decking professional to handle your deck repairs in Boston. By law, Massachusetts decking pros must register as a Home Improvement Contractor (HIC) to repair existing decking.
However, if your project involves building a new deck or modifying any structural elements, your pro will need an HIC registration and a Construction Supervisor License (CSL) from the Commonwealth.
Permits
In Boston, you must have a building permit to make alterations to your home. You’ll need either a short-form or long-form building permit, depending on the type of deck repair and the location of your deck. Here are the estimated costs for those permits:
Short-form building permit: $20 primary fee plus $10 per $1,000 of the estimated cost of work
Long-form building permit: $50 primary fee plus $10 per $1,000 of the estimated cost of work
A deck repair pro in Boston, MA, can explain which permits you need and work with the city to obtain them on your behalf.
Sales Tax
Be sure to factor in Boston’s 6.25% sales tax into your deck repair budget, too. For example, if your project materials cost $1,200, you’d pay $75 in sales tax.
Does Deck Repair Increase Home Value?
If you’re thinking about selling your house in Boston, having a well-maintained deck can increase your home’s overall appeal. For buyers, decks are an attractive feature because they offer a private place to relax and enjoy New England’s warm summer weather.
According to the Journal of Light Construction (JLC) Cost Versus Value Report, Boston homeowners who add a wooden deck can expect to recoup 66.4% of the project costs. For composite decks, that figure increases to 72.5%.
