Juan Aguirre - Longevity Expert for Chicago Homeowners
Most contractors focus on what you can see. I focus on what you can’t. I founded J&S Construction LLC because I saw too many "luxury" remodels failing from the inside out. My approach is simple: I treat every home like a permanent landmark. Whether it's a kitchen gut or a custom pavilion, J&S prioritizes structural honesty so your investment outlasts the trends.
The J&S Philosophy +
At J&S Construction LLC, we believe a home is like a living organism; it needs a skeleton that can withstand a Chicago winter without flinching. My personal philosophy is "Over-Built is the Only Way."
To me, a job well done isn't just about a happy client on move-in day—it's about a client who is still happy ten years later. At J&S, we don’t just build to code; we build to a standard of excellence that ensures every deck, bath, and addition is a testament to the art of construction.

Custom Pavilions & High-Load Decking for Premium Hosting
A deck is a bridge between your home and the elements; it must be engineered to withstand both.
At J&S Construction LLC, we don't build standard backyard platforms. We build architectural extensions of your living room. We solve the problem of rotting wood and sagging supports by utilizing advanced footing techniques and weather-resistant framing, ensuring your pavilion remains a permanent sanctuary.

Direct feedback from the homeowners who prioritized engineering and longevity with J&S Construction.
"I’ve worked with dozens of contractors, but Juan operates on a different level. It’s not just about the finishes—it’s the precision of the framing and the way he manages the site. He caught structural issues three other 'pros' missed entirely."
"The consultation phase was a game changer. Juan didn't just give me a quote; he taught me about load-bearing mechanics and sub-floor waterproofing. I feel 10x more confident in the long-term equity of my home now."
"Most professional job site I've ever seen and a builder who actually answers his phone. He engineered our pavilion to handle Chicago winters when everyone else suggested a 'kit' that wouldn't last. No hype, just structural honesty."
