You plan a deck for months, pick out the furniture, and imagine summer evenings there. Then, after the first season, you realize the afternoon sun makes it unusable from 2 PM to 6 PM. Or the wood starts cupping within a year. In 2026, Joliet homeowners are making five specific deck design mistakes that turn a $15,000 to $35,000 investment into a source of frustration. Here is what to avoid and how to get it right the first time.
1. Ignoring Joliet's Sun and Wind Patterns: Why Your Layout Fails
Joliet sits in USDA Hardiness Zone 5b, which means hot, humid summers and cold, windy winters. The most common mistake people make is designing a deck without considering where the sun hits and which direction the prevailing winds blow. A deck that faces west without shade is a baking zone from mid afternoon until sunset. You will end up eating inside and using the deck only after dark.
Before you finalize your layout, spend a few afternoons walking your yard at different times. Note where shadows fall from your house, trees, and neighboring structures. In Joliet, prevailing winds come from the southwest during summer, so if you plan a dining area without a windbreak, you will be chasing napkins and dealing with gusts that make outdoor meals unpleasant. A pergola with adjustable louvers or a partial privacy screen can make a deck usable in all but the worst weather.
Burns Carpentry always does a site evaluation that includes a sun and wind analysis before starting a Deck Building project. We have seen homeowners spend thousands on a layout that looked great on paper but turned out to be a wind tunnel or a solar oven. Fixing orientation after the deck is built means costly modifications or just living with a design that does not work.
2. Choosing the Wrong Materials for Joliet's Climate: Wood vs. Composite
The wood versus composite debate is not just about looks or cost. Joliet's freeze-thaw cycles, high humidity, and harsh UV rays punish deck materials differently. Pressure treated pine, the most common budget option, typically lasts 10 to 15 years in this climate if you seal it every two years. If you skip a season, the wood starts checking, splitting, and cupping. A 300 square foot wood deck costs roughly $4,500 to $7,000 installed, but over 15 years you will spend another $1,500 to $3,000 on sealers, stain, and labor.
Composite decking, like Trex or TimberTech, costs more upfront: about $8,000 to $12,000 for that same 300 square foot deck. But it never needs staining or sealing. In Joliet's humidity, composite resists mold and mildew better than wood. The catch is that cheap composite brands can fade and warp in direct sun. Stick with capped composite lines that have a protective shell, and make sure the substructure is rated for composite weight. Composite is 20 to 30 percent heavier than wood per square foot, so your framing needs to be designed for it.
Burns Carpentry offers both wood and composite installation. For most Joliet homeowners, we lean toward composite if you plan to stay in the house more than five years. The maintenance savings alone justify the higher upfront cost. If you love the look of natural wood and are willing to reseal every two years, a properly built wood deck with hidden fasteners and a good stain can be stunning. Just know what you are signing up for.
3. Skimping on Railings and Stairs: Safety Code Violations You Miss
Joliet follows the 2021 International Residential Code, which has specific requirements for deck railings and stairs. The most common violation we see is railing height. Decks more than 30 inches above grade need guardrails at least 36 inches high. But many homeowners try to save money by using 30 inch rails or skipping them on low decks where they are still required by code. A fall from even a 30 inch deck can cause serious injury, especially for children and older adults.
Stair tread depth is another frequent miss. The code requires a minimum 10 inch tread depth and a maximum 7.75 inch riser height. If you use standard 2x6 lumber for treads, you will only get about 9.25 inches of usable tread, which is too shallow. This makes stairs feel cramped and likely to cause trips. Also, every set of stairs over four risers needs a handrail on at least one side. Handrails must be between 34 and 38 inches high and graspable, meaning you cannot use a 2x4 nailed flat. You need a proper round or oval rail.
Burns Carpentry handles all Deck Building permits for Joliet and the surrounding areas, including Cary, Aurora, and Naperville. We have seen decks flagged by inspectors for missing post anchoring, improper ledger board attachment, and inadequate footings. A 12x16 deck needs footings that go below the frost line, which in Joliet is 42 inches deep. Skipping this step means the deck will heave in winter. The cost to fix an unpermitted deck after an inspection failure can easily hit $5,000 to $10,000.
4. Forgetting Future Use: Why Your Deck Lacks Storage and Seating
A deck is not just a platform. It is an extension of your home, and how you use it will change over time. The mistake is building a flat, empty rectangle and assuming you will add furniture later. But then you realize you have nowhere to store cushions, grilling tools, or gardening supplies. You end up with a plastic deck box that looks out of place and takes up valuable square footage.
Plan for built-in storage from the start. A bench along one side with a hinged lid gives you 20 to 30 cubic feet of hidden storage. That is enough for all your cushions, a few folding chairs, and a small cooler. If you entertain often, consider a built-in bar or a serving counter. A pergola with integrated planters and a ceiling fan makes the space feel like a room, not just a walkway.
Burns Carpentry specializes in custom Pergola Building and Composite Deck designs that include these features. We have built decks with hidden pull-out trash bins, integrated lighting, and even a small herb garden planter. Think about your life five years from now. Will you host parties? Need a dog run? Want a hot tub? A deck that is designed for future use costs only slightly more upfront but is far more functional.
5. Overlooking Permits and HOA Rules: Costly Delays and Fines
This is the mistake that costs the most money and time. Many homeowners assume a small deck does not need a permit or that their HOA will not care. In Joliet, any deck attached to the house or over 200 square feet requires a building permit. The permit fee is typically $150 to $400 depending on size, but the real cost of skipping it is the stop work order and the fine, which can be $500 to $1,500. Plus, if you sell the house, an unpermitted deck can kill a sale or force you to tear it down.
HOAs in Joliet communities like those in Shorewood, Plainfield, and Naperville have strict rules about deck height, railing style, material colors, and even the type of wood you can use. Some require a design review before you start. We have seen homeowners order $8,000 worth of composite decking only to find out their HOA requires natural wood. Or they build a two-level deck when the HOA only allows single-level structures. Fixing these mistakes after the fact is expensive and frustrating.
Burns Carpentry manages the entire permit process for every project, including Deck Building in Cary, Arlington Heights, and Chicago. We also help you navigate HOA requirements before we start. We will pull the drawings, submit the paperwork, and schedule the inspections. You do not have to deal with a single government office. This alone saves most homeowners three to five hours of headache and potential fines.
Frequently Asked Questions
How much does a new deck cost in Joliet in 2026?
For a basic 12x16 wood deck, you are looking at $5,500 to $8,500 installed. A composite deck of the same size runs $9,000 to $14,000. Add a pergola, built-in seating, or lighting and the price goes up accordingly. Burns Carpentry provides free estimates that break down every cost so there are no surprises.
Does composite decking get too hot to walk on in Joliet summers?
Yes, dark colored composite can get uncomfortably hot on 90 degree days. Light gray, tan, or brown shades stay cooler. We recommend a lighter color and a shade structure like a pergola if the deck faces south or west. You can also add an outdoor rug in high traffic areas.
How long does a deck building project take in Joliet?
Most projects take three to five weeks from consultation to completion. That includes design, permitting, material ordering, and construction. Weather can cause delays, especially if we hit a rainy stretch. We keep you updated every step of the way.
Do I need a permit for a ground level deck in Joliet?
Yes, any deck attached to the house or over 200 square feet needs a permit, even if it is ground level. Freestanding decks under 200 square feet may not require one, but check with Joliet's building department to be sure. Burns Carpentry handles all permits as part of our service.
