Deck with repaired deck boards

If you have a deck in your yard, it requires maintenance and repair. If you’ve left things too late, you may be looking at a complete renovation instead. However, if there are just places here and there that need attention, repairing it is a more economical and convenient choice. Still, it helps to know how much the repair work is going to cost you. So, how much does it cost to repair a deck? The short answer is: it depends. Here are the factors that affect the cost of repairs:

Size of Deck

The size of your deck is a fundamental aspect with regards to calculating the cost of your deck repairs. If you’re thinking of hiring a professional and want to get some quotes for the work you need done, one of the first things you’ll be asked is what size the deck is. You should be prepared for this question. It’s easy to measure and calculate this, simply multiply the length by the width (in feet) to find the square footage.

Once you have these measurements, pricing material and labor gets a lot easier because you can calculate how many deck boards, hidden fasteners, and screws you need for your deck. If you want to find out how many boards you’ll need, measure the length of the boards you currently have to use as an estimate.

Let’s not forget the other elements of a deck, however. When calculating repairs, it is easy to forget the railings and balusters that make up a significant proportion of your deck. As such, you can estimate the number of balusters you need for your railing by taking into account the length of the railing and the number of posts it has.

Extent of Work Needed

This, along with the size of your deck, is the most crucial factor with regards to cost. If the damage is minor, the price will be minor. Similarly, if the damage is extensive, be prepared to pay thousands to get your deck looking in good shape again.

DIY Versus Hired Labor

Doing your deck repairs yourself will be more affordable, but consider that professionals often have the tools needed and carpentry skills to create a long-lasting repair. Hiring professional help might seem more expensive in the short term, but it can save you a lot of money in the long-term.

If you’re adamant about doing things yourself, supplies for repairing your deck can cost anywhere from tens to hundreds of dollars. If staining or varnishing your deck, a tin of good quality stain costs around $40. To get a more long-lasting finish, consider cleaning or power-washing your deck first. Deck cleaner costs around $10 to $20. Thus, cleaning and staining your deck will cost around $60 or more depending on its size.

For more extensive repairs like replacing rotten deck boards or completely redoing some or all of your deck, the costs go up dramatically. Redoing the entire thing will require a budget of thousands while repairing a part will cost hundreds.

Estimated Costs

It’s clear that there are many things to consider when you’re trying to calculate the cost of your deck repairs. However, it’s still possible to provide some ballpark estimates for you by assuming measurements for some of the variables. Assuming, then, that you need a section of your deck replaced entirely, here are some estimated repair costs for deck flooring:

Costs for common deck board materials
Material Cost per Square Foot
Pine, pressure treated flooring $2.50
Redwood, select heart flooring $4.35
5/4″ x 6″ recycled composite lumber $8.06
2″ x 8″ recycled composite lumber $14.27
