Who We Are

A Team Committed to Excellence

Jonathan (Yoni) Nissim

How It Started

Yoni built I Know A Guy Flooring on one idea: be the contractor people pass along by name. After hundreds of projects across Los Angeles, that's exactly what happened. Homeowners, builders, and designers kept calling because the work held up and the job got done. The name fits. When someone needs floors done right, they know a guy.

The Hard Jobs Others Skip

Most flooring failures start below the surface. Bad subfloors, trapped moisture, and uneven slabs wreck good floors fast. We handle the problems other contractors walk away from—moisture mitigation, custom stair systems, complex leveling. That's where our craftsmanship shows. You get a floor that looks flawless and a crew that solved the issue instead of covering it up.

Our Services in California

FLOORING WORK THAT HOLDS UP IN REAL HOMES

Hardwood Flooring Installation

Hardwood Flooring Installation

Solid hardwood changes a room. We install oak, walnut, maple, and wide-plank floors that look clean and last for decades. Every board gets laid with care, tight seams, and proper acclimation so it sits right through every season. You get a floor that feels solid underfoot and adds real value to your home.

Custom Stairs & Stair Fabrication

Custom Stairs & Stair Fabrication

Stairs are tricky. They need to match your floors and hold up to daily traffic. We build and fabricate custom stair systems, from treads and risers to railings, that fit your space exactly. The result is a staircase that flows with the rest of your home and feels rock-solid every step.

Hardwood Floor Sanding & Refinishing

Hardwood Floor Sanding & Refinishing

Old floors hide good wood underneath. We sand down worn, scratched, or dull hardwood and refinish it to look new again. This costs less than full replacement and brings back the grain and color you fell in love with. Most floors can take several refinishes over their lifetime.

Subfloor Leveling & Preparation

Subfloor Leveling & Preparation

A great floor starts with what's under it. Uneven or damaged subfloors cause squeaks, gaps, and early failure. We level and prep the surface before a single plank goes down, so your finished floor sits flat and stays quiet. This step is where a lot of contractors cut corners. We don't.

Luxury Vinyl Plank Installation

Luxury Vinyl Plank Installation

Luxury vinyl handles water, pets, and heavy traffic without flinching. We install LVP that looks like real wood but stands up to kitchens, bathrooms, and busy hallways. It's a smart pick for families and rental properties. You get the look you want with far less worry about spills and wear.

Moisture Mitigation & Subfloor Repair

Moisture Mitigation & Subfloor Repair

Trapped moisture ruins floors from below. We test for moisture and install proper barriers and repairs before installation, so your floor doesn't cup, warp, or rot down the line. Damaged subfloors get fixed, not covered up. This is the kind of behind-the-scenes work that separates a floor that lasts from one that fails.

Engineered Hardwood Flooring

Engineered Hardwood Flooring

Engineered hardwood gives you a real wood surface with more stability than solid planks. It handles humidity and temperature swings better, which matters in many LA homes. We install it over concrete slabs and in spaces where solid hardwood struggles. You get the look of real wood with added peace of mind.

Wide Plank Hardwood Installation

Wide Plank Hardwood Installation

Wide planks make a room feel bigger and more open. They show off the wood grain and create a clean, modern look that designers love. Wider boards need careful installation to stay flat and tight, so we handle acclimation and subfloor prep with extra care. The payoff is a floor that turns heads.

Pet-Friendly Flooring Installation

Pet-Friendly Flooring Installation

Pets are hard on floors. We install durable, scratch-resistant flooring built to handle claws, spills, and daily traffic without showing the wear. That means the right materials and finishes for homes with dogs and cats. You keep a floor that looks good and stands up to the chaos of a busy household.

Floor Repair & Board Replacement

Floor Repair & Board Replacement

Damaged boards don't always mean a whole new floor. We replace cracked, water-damaged, or warped planks and blend the repair into your existing floor so it disappears. This saves you money and extends the life of what you already have. Done right, you won't be able to tell where the repair was.

Stair Refinishing

Stair Refinishing

Worn stair treads take a beating and show it. We sand and refinish your existing stairs to match your floors and bring back a clean, fresh look. Refinishing costs less than rebuilding and restores the surface where it gets the most use. Your staircase ends up looking sharp and feeling solid again.

Hardwood Floor Staining

Hardwood Floor Staining

The right stain transforms the whole feel of a room. We stain hardwood in the color and tone you want, from light natural finishes to deep, rich shades. Proper sanding and prep make the color go on even and last. You end up with a floor that matches your style and the rest of your home.

Squeaky floors? Uneven slab? Old wood that's seen better days?

Why Choose I Know A Guy Flooring

The Difference is Clear

We Solve, Not Cover

Plenty of contractors install over problems and hope for the best. We find the root issue—moisture, bad subfloor, settling—and fix it first. That's why our floors don't squeak, gap, or lift a year later. You pay once and the job stays done.

Owner On The Job

Yoni runs the work, not a crew of strangers you never meet. You deal with the person whose name is on the company. That means clear answers, real accountability, and floors finished to one standard. No middleman, no guessing who's responsible.

Built For Tight Schedules

Builders and designers trust us because we hit deadlines without cutting quality. We coordinate around your construction timeline and keep the job moving. When you're juggling trades and a hard finish date, a flooring crew that shows up and delivers matters.

High-End Craftsmanship

We work in some of LA's most discerning homes, from Beverly Hills to Pacific Palisades. That demands precision—tight seams, clean transitions, flawless finishes. The standard our clients expect is the standard we bring to every job, large or small.

Frequently Asked Questions

Got Questions? We’ve Got Answers!

How much does hardwood flooring installation cost in Los Angeles?

Cost depends on the wood species, square footage, and how much subfloor prep your home needs. Solid hardwood runs higher than engineered or luxury vinyl, and tricky layouts or stairs add to the total. The honest answer is that every home is different. Call us for a free estimate and we'll give you a real number based on your space.

Can you refinish my old hardwood floors instead of replacing them?

Yes, in most cases refinishing is the better and cheaper option. If the wood is solid and thick enough, we sand it down and refinish it to look new again. Refinishing costs a fraction of full replacement and most hardwood floors can handle several refinishes over their life. We'll inspect your floors and tell you honestly whether refinishing or replacement makes more sense.

Do you fix squeaky or uneven floors before installing?

Yes, and this is where we stand apart from a lot of contractors. Squeaks and unevenness almost always trace back to the subfloor. We level and repair the surface underneath before any new flooring goes down. Skipping that step is why so many floors fail early, so we never cut that corner.

How long does a hardwood floor installation take?

Most residential installations take a few days to a week, depending on square footage and prep work. Solid hardwood also needs time to acclimate to your home before installation, which we factor into the schedule. Stairs, refinishing, and subfloor repairs can add days. We give you a clear timeline upfront so you can plan around the work.

What's the difference between luxury vinyl and real hardwood?

Real hardwood is natural wood that lasts decades and can be refinished, while luxury vinyl is a synthetic plank that resists water and heavy wear. Hardwood adds more home value and a true wood feel. Luxury vinyl handles kitchens, bathrooms, and pets better. We install both and help you pick the right one for each room and budget.

Do you build custom stairs to match my floors?

Yes, we fabricate custom stairs and match them to your existing or new flooring. That includes treads, risers, and railings built to fit your exact space. Matching stairs to your floors creates a seamless look that builders and designers ask for often. We handle the whole process so the staircase flows with the rest of your home.

Do you work with builders and interior designers?

Yes, a large share of our work comes from builders and designers across Los Angeles. We coordinate around construction schedules, hit hard deadlines, and deliver the precision high-end projects demand. Trade professionals keep calling us back because we communicate clearly and get the job right the first time. We're comfortable as one part of a larger build.

Which areas of Los Angeles do you serve?

We serve LA's westside and surrounding luxury markets, including Pacific Palisades, Brentwood, Beverly Hills, Bel Air, Malibu, Holmby Hills, Santa Monica, and Calabasas. Our work centers on homes that demand precision and clean results. If you're near these areas and need flooring done right, give us a call to confirm we cover your neighborhood.
