Trex vs. TimberTech vs. AZEK: Which Composite Decking is Best in Chicago?
Choosing the right composite decking is one of the most important decisions for homeowners looking to build a low-maintenance, long-lasting deck. If you’re in Glenview, Wilmette, Winnetka, Glencoe, Northbrook, Lake Forest, Lincolnshire, Evanston, Highland Park, Naperville, Barrington, Schaumburg, Riverwoods, or Chicago, you need a deck that can withstand harsh winters, hot summers, and year-round weather changes.
The three biggest names in composite decking are Trex, TimberTech, and AZEK—but which one is best for your home?
This guide will break down the durability, maintenance, appearance, price, and warranty of each brand, helping you make an informed decision.
1️⃣ Durability: Which Composite Deck Lasts the Longest?
Chicago-area homeowners need a deck that can handle extreme temperature swings, moisture, and heavy foot traffic.
Trex is made from 95% recycled materials and features a solid core with a protective shell, making it highly resistant to moisture, rot, and warping. It performs well in humid conditions but may show some scratchingover time.
TimberTech offers a composite core with a protective polymer cap, making it highly resistant to stains, fading, and moisture. It provides better scratch resistance than Trex, making it ideal for high-traffic decks.
AZEK (by TimberTech) is a premium PVC decking option, meaning it contains zero wood fibers. This makes it 100% resistant to moisture, mold, and mildew, making it the best choice for wet climates and lakefront homes in Evanston and Lake Forest.
2️⃣ Maintenance: Which Decking Requires the Least Upkeep?
One of the biggest advantages of composite decking is its low maintenance compared to traditional wood. Unlike wood decks, Trex, TimberTech, and AZEK never require sanding, staining, or sealing.
Trex requires occasional cleaning with soap and water to remove dirt and debris. However, its protective shell minimizes mold and mildew buildup, making it a great choice for low-maintenance outdoor living.
TimberTech has a more advanced capping layer than Trex, offering increased stain and moisture resistance. It's a great choice for homes in humid or rainy areas.
AZEK is the most low-maintenance option since it is made from 100% PVC. It is completely resistant to mold, mildew, and water damage, making it the best choice for decks near pools or water features.
3️⃣ Appearance: Which Composite Decking Looks the Most Realistic?
For homeowners in Winnetka, Glencoe, and Highland Park who want a deck that mimics natural wood, choosing the right brand is crucial.
Trex offers deep wood-grain textures and comes in earthy tones like brown, gray, and redwood shades. While it looks realistic, its texture is slightly more uniform compared to TimberTech.
TimberTech provides the most authentic wood-look decking, with varied grain patterns, multiple color blends, and matte finishes that resemble natural hardwoods like mahogany and cedar.
AZEK has a smoother texture and a higher-end look, but it may not feel as natural as Trex or TimberTech. However, it comes in a wide range of premium colors, making it a favorite for luxury outdoor spaces.
4️⃣ Price: Which Composite Decking Fits Your Budget?
The cost of composite decking varies based on brand, series, and installation costs in Chicago and surrounding suburbs.
Trex is generally the most affordable of the three, making it a great option for budget-conscious homeowners in Schaumburg, Riverwoods, and Evanston. Its Select and Enhance series offer a cost-effective balance between price and durability.
TimberTech falls in the mid-to-high range, but its longer lifespan, increased durability, and more realistic wood look justify the investment. Homeowners in Naperville, Highland Park, and Wilmette often choose TimberTech for its premium appearance and high scratch resistance.
AZEK is the most expensive of the three due to its 100% PVC construction, which makes it extremely durable, water-resistant, and low-maintenance. It’s a great choice for high-end homes in Lake Forest and Winnetka.
5️⃣ Warranty: Which Decking Brand Offers the Best Protection?
A strong warranty ensures your deck will last for decades without issues.
Trex provides a 25-year limited warranty on most of its composite decking, with fade and stain protection.
TimberTech offers a 30-to-50-year limited warranty, depending on the collection.
AZEK has the longest warranty, with a 50-year limited warranty and a lifetime residential warranty on certain collections.
