What’s the Cost to Build a Deck in NJ?

Cost to build a deck in NJ: The average deck is constructed from three main features – the decking, the frame / foundation, and the railings. Decking and rails can be made from wood, composite materials or Metal. Foundation and Frame are always wood and concrete. The costs between the different rail and decking choices as well as additional trim options will usually serve as the overall deciding factors. While wood comes in at a much lower price it requires yearly maintenance. Composite materials are more expensive up front but have a much longer lifespan and are maintenance free.

For the purpose of this post we’ll consider the costs and requirements for a wooden deck measuring 16’x20′. Keep in mind this information is for NJ residence on the East Coast only. Prices for labor and materials vary from place to place.

The cost to build a deck in NJ with wood rails and decking averages at $9,600 or $35 per square foot. Remarkably, the project has an impressive resale value, a homeowner can expect to recoup around 80% of the total construction costs for such a deck at the time of sale.

This is considering the deck has a single set of stairs and is approximately 3 steps high. Stairs are more expensive to build than the deck itself so higher decks or decks with more than one set of steps are more money.

Deck Cost Breakdown

This is not a DIY project. The average homeowner doesn’t have the advanced knowledge of carpentry that’s demanded by such a project. You also need knowledge of local building codes and construction practices. And if you want to get value out of your new deck when you eventually sell your home it has to be built to a high level of quality that an average homeowner just can’t achieve.

Deck costs Include:

  • Materials – the deck described would require pressure treated framing lumber, pressure treated decking and railings. Decking installed in a basic linear array with appropriate galvanized screws (usually around 15 pounds) or clips which give the deck a screwless look to complete construction.
  • Excavation and site preparation – costs will vary according to the level of work necessary, but all projects will require leveling and the insertion of form tubes for the concrete footings.
  • Concrete – the 6×6 posts used as the framing for the structure must be set on top concrete footings.
  • Stairs and Railings  – in NJ it is illegal for any contractor to construct a deck without also ensuring that a set of stairs and safety railings were in place unless the deck is ground level.
  • Trim – On a wood deck typically the frame and stairs are kept as exposed wood. You can add Azek or some other form of Fascia or deck trim.
  • Deck Skirt – The bottom space or skirt of the deck is left open. You can close it off with lattice or make it solid if you like at additional cost. The price for this will depend on the height of the deck and material used but generally is not that expensive. Add an extra $2000 for a deck this size for a solid skirt, $1,000 for lattice considering it’s only 3 steps high.

Enhancement and improvement costs

A number of things goes into determining the cost to build a deck in NJ. Like buying a car or building a new house, most people want more than just the basics. Options can add a lot to the total construction costs needed to build your new deck. Unlike when buying a car, options in the construction business tend to pay off in the long run. Generally when selling your home you’ll get back around 80% of the total cost of the deck in resale. That can actually go up when adding options which are relatively cheap when compared to the overall cost to build a deck in NJ.

Some of these options even make great DIY projects.

  • Stain or seal – even if the decking is pressure treated it may be a good idea to seal or stain it against the weather. This is especially true in NJ where summer temperatures can be high and winter weather includes a lot of precipitation and freezing temperatures.
  • Electrical service – most decks should have at least a single electrical outlet appropriate for outdoor use. This will allow the homeowner to have access to such service without running extension cords into the home or the basement. Generally this is already on the exterior of the home but can be added if need be.
  • A pergola or awning – uncovered decks can become unpleasant during the worst of the hut summer. A pergola or awning can be added to the deck at additional cost.
  • Step Lighting – most homeowners enjoy having step lighting or other forms of low voltage “mood” lighting such as post cap lights.
  • Plumbing – Consider running a gas line for a grill or outdoor kitchen and water for a wet bar, prep sink or outdoor shower.

NJ Wood Deck Cost Summary

What does it cost to build a deck in NJ? Approximately $35 a sq. ft. will buy you a deck built from wood with concrete footings, wood decking and wood rails with a single set of steps. The deck will be built to all local codes and pass all applicable inspections. Pretty basic but affordable.

As with any remodeling or building project, it’s best to get several estimates and to discuss your ideas with an architect or designer so you can get a range of prices and find one that suits what you can afford. Gambrick has a price match guarantee so no matter what prices you get, as long as they’re from a qualified, skilled deck builder in NJ we’ll beat it.

Take into consideration what your house is worth and how long you plan to live in it. You don’t want to overspend on an oversize deck that does not suit the scale of your home nor do you want to skimp on the size of the deck if you have a large home. If you plan to sell your home shortly after the deck is complete, you might not want a deck that costs too much and that you will not get to enjoy for long.

Generally, gathering three good estimates may be enough. People say pick the one in the middle but that’s not a great strategy. If a great deck builder gives you a good price you should take it. Just picking the middle price out of 3 without considering anything else is pretty dumb and could get you into trouble. Be open and honest with your designer. He or she may be able to suggest ways to save you money but still get the deck you want.

NJ Composite Trex Deck Cost

On average synthetic decks run about $5 more per sq ft for both decking and rails than pressure treated decks. So the same deck with trex decking and composite railings would be $40 a sq ft. But again keep in mind that for decks with long flights of steps or multiple sets the cost per square foot will be higher.

You could also add Azek trim to cover all the pressure treated lumber. This is called Fascia. Azek fascia is figured in linear feet not square feet. Add an average of another $5 per sq. ft for the option. Bringing this deck to $45 per sq ft.

If this deck was a 2nd story deck you could add an under deck or dry deck product. This is basically a gutter system that covers the under side of the deck keeping it dry when it rains. This adds an average of about $12 per sq ft to the deck.

As you make your decision keep in mind the cost of yearly maintenance for a pressure treated wood deck vs. $0 a year for a composite one.

These numbers are just estimates. Actual costs will vary because every deck is different, but the prices we charge are always very close to these. What is the cost to build a deck in NJ with all the options? A recent deck we finished with Trex decking and railings, Azek fascia, lighting, under decking, custom built Azek columns and Pergola cost around $65,000 not including the patio. All in was about $100,000 including the custom outdoor fireplace. It was around 1,000 sq ft. with another 500 sq ft of patio.

Decks are all custom so it’s best to come up with a budget first and then design the deck to match.

Additional Costs to build a Deck in NJ

Some additional costs you’ll have to pay are zoning and building fees for permits. You’ll also need a set of plans. A homeowner can draw they’re own plans and we can help, but a builder can’t draw plans for a homeowner. If you don’t want to draw them up we have an architect that can do it for you. I Can’t say exactly how much that is but I’d figure at least $1000 for something very basic.

Many factors affect cost to build a deck in NJ, such as level of finish and site preparation, but the price of professional installation always makes up a big chunk of the bill. Knowing this can help prevent sticker shock.

In general you should follow the old fashioned 50/50 rule: “For every dollar spent on materials and supplies, expect to spend another dollar to have it installed.”  And if your contractor quotes a cost per square foot, it’s probably for labor and materials combined.

In addition to supplies and labor, the climate of the location and slope of your property can also affect the cost to build a deck.

Foundations for decks in cold climates are typically more expensive because they need deeper, freeze-proof footings, while “sloped sites can create additional expenses but also present interesting design opportunities.”

New Deck Shape

All these prices assume the deck your building is square. If you want a deck with multiple levels, cut outs or some complicated shape or a round design, it’ll be custom pricing. Round is by far the most expensive. We’ve done round decks in the past that started at $100 a sq. ft. Multi level would be the next highest followed by a custom designed single level deck. When calculating the cost to build a deck in NJ always remember each deck is unique.

Try to use some common sense when figuring out deck construction costs. If you want some elaborate deck design you’ve seen in a magazine it’s going to cost more than a simple square deck. Just like when buying a car, options are expensive and add up. They tend to be some of the nicest features on the car but they all cost money. It’s easy to double the cost of a basic deck once you’ve added in every available option so make a list of what you want most before you start designing.

Additional Deck Option Costs

Deck options are all priced separately as per the customers design. There’s really no way of giving you a good idea of what they cost because all this stuff is custom. It depends on the sizes and materials used as well as the design. Also for things like electrical and gas lines the price varies depending on how we can tap into the existing homes supply lines. For all these reasons and more I can’t give prices for extras here. Just keep in mind it can get expensive so make a list of things you want before you start designing and when in doubt just ask. It’s easy to figure out what all this stuff costs once we start designing the deck.

Value for Your Money

A new deck can expand the outdoor living space of your home and increase your home’s value. Decks are consistently one of the improvements you can add to your home that will increase its value. According to Hanley Wood’s Remodeling magazine’s annual 2011-12 Cost vs. Value Report. The cost to build a deck in NJ is recouped an average of 80% at resale. That’s always something to consider when thinking about what the cost to build a new deck is. It’s a good investment vs. a bad one like putting the money into a new car that goes down in value the second you drive it off the lot.
The magazine’s survey indicates that a mid range wood deck addition that costs $10,350 in the Mid-Atlantic region of the U.S. will recoup about 70 percent of its value at resale on the national average. In the same study, a composite deck addition that cost $15,579 recouped 62.8 percent on the national average. Even in a down housing market, a deck upgrade can mean more money in your pocket when you sell your home. Any way you look at it decks are a solid investment. They hold their value extremely well when compared to other home improvements in NJ.

How to plan your deck installation

Know your limits: A deck is a permanent addition to your home, just like a bathroom or kitchen remodel. Decks must follow local building and zoning codes, such as required distance from property lines, that may limit the size and scope of the project. Upkeep is another limiting factor to consider: Composite decking and other synthetic materials generally cost more but require less maintenance, making them cheaper in the long run.

Make a budget: Start with a list of “wants” and “must-haves,” as well as the amount you’re willing to spend. When considering the cost to build a deck in NJ have a pre-determined budget like you’d have when shopping for a new car or home.

Then, think about the size and value of your home, as well as how long you plan to live there. A large, luxurious home might look funny with a small, simple deck. And an oversized deck with lots of personal features may not make sense for a small house you might outgrow in a few years. Work with a professional builder to fit as many must-have elements into the design as your budget will allow.

Things To Consider

Balance cost with benefits: When planning a deck, increased comfort and living space should be the main goal. Should you ever refinance or sell, improved home value and marketability may be a happy side effect. Never forget the cost to build a deck in NJ is always a factor but should be balanced out with all the other benefits of building a new deck.

Find the right contractor: Peace of mind and a workmanship warranty are usually worth the added cost of hiring a pro. Still, some homework is required to find the right one. When considering the cost to build a deck in NJ make sure to:

  • Compare quotes from three or more deck contractors to ensure a fair price
  • Read credible reviews of all potential contractors as well as the materials they use
  • Request pictures of past deck projects, and don’t be afraid to ask whether the initial timeline and estimate were met
  • Ask the contractor’s previous clients if they are satisfied with the service and finished product
  • Confirm that contractors are bonded, licensed and insured (if required) by contacting your local building department or state consumer protection agency before hiring them

Tips to reduce the cost to build a deck in NJ

Keep it simple: Eliminating curves and other fancy design features will make a difference. Although reducing the overall size of the deck is where you’ll likely find the biggest savings, Wormer said. Matching deck dimensions to standard lumber lengths and using pre-made concrete piers, or footings, can also reduce cost.

Choose wood, but carefully: Untreated wood decks are generally the cheapest to install, but don’t forget long-term costs. Wood decks require yearly maintenance and deteriorate quickly if they don’t get it. Investing in pressure-treated wood or a composite deck could save time and money later, especially if you plan to stay in the house for a long time.

Time it right: The warmer months are most popular for deck building, so scheduling your installation in the offseason could be a way to save. With fewer jobs competing for their time between November and March, contractors may offer reduced labor rates and faster scheduling to gain your business.

Not a DIY Project

DIY if you dare: Pulling permits, interpreting building codes and properly installing foundation supports are above the skill level of many DIYers. In most cases, paying a pro to install a deck is worth the peace of mind. But, if you’re confident in your carpentry skills or have friends who are experienced builders, doing it yourself can significantly reduce the cost. There are many resources and how-to videos available online, especially if you’re content with a simple, rectangular design.

In some cases, it could make sense to have a professional handle the harder parts of building a deck, while leaving the easier tasks to you. For example, a pro could install an unfinished wood deck and you could do the sealing, staining or painting. It’s fairly easy for any homeowner and would save some money.

When In Doubt Ask?

The best way to figure out what the cost to build a deck in NJ is, is to ask. Call a professional like Gambrick and tell them what your thinking of doing.
