"The stone work KLJ did in our kitchen is absolutely flawless. Perfect seams, beautiful finish, and they were done two days ahead of schedule. These guys are the real deal."

How We Work
Most homeowners dread the remodeling process. We built ours around transparency — so you always know what's happening, what it costs, and when it's done.
We come to you. No pressure, no sales pitch — just a real conversation about your project, your goals, and what's realistic for your space and budget.
You get a line-item estimate, not a ballpark. Every material, every trade, every timeline milestone — spelled out before we ever break ground.
KLJ's owner is on every job site. That's our commitment. You'll have one point of contact who knows your project inside and out.
We don't consider a project done until you do. Every punch-list item resolved before we leave the job site for the last time.
Service Area
We take jobs from the five boroughs through Nassau and Suffolk County, out to the East End. If you're serious about the work, location isn't the issue.
We've built relationships across Long Island and New York City for over 15 years. Here's what homeowners say after working with us.

They designed and built our entire backyard — patio, outdoor kitchen, and pool. It's better than anything I saw on Pinterest. Completely transformed how we use our home.

We've had other contractors before. KLJ is a different experience entirely. They showed up every day, communicated constantly, and the final product is stunning.
