Frequently Asked Questions
Do I need a building permit for a new deck in Lemont, IL?
Yes. The Village of Lemont requires a building permit for all new deck constructions, layout expansions, and structural modifications. Warner’s Decking manages the entire architectural submission, zoning verification, and municipal inspection process for you.
How much does a Trex composite deck cost?
Base pricing for a standard 12×12 platform typically starts at $15,000. What affects the price the most is: sq footage, stairs, and the product chosen to build.
Why is composite decking better for Lemont’s climate?
Traditional wood decks absorb moisture in humid Illinois summers. They can also crack during winter freeze-thaw cycles. Trex composite decking has a bonded protective shell that keeps out water. It helps prevent rot, warping, and splitting during harsh Midwest weather changes.
How long does the actual deck building process take in Lemont?
Once the city approves the permits and the site is ready, builders finish most standard composite decks in 1 to 3 weeks. Elevated walkout decks with custom stairs or integrated pergolas may take slightly longer. We provide a definitive timeline with your project estimate.
What warranties do you offer?
We offer dual-layered protection. Every composite project includes a 25-year manufacturer warranty against fading, staining, and material damage. It also includes our 10-year workmanship warranty.
