ABOUT M&L

A family business
building outdoor spaces
across St. Louis since 2013.

M&L Exterior Design started with a simple frustration: most paver work in Missouri fails within a few winters because contractors cut corners on the base.

We do it differently. We're not a sales-first crew that subs out the actual install. Every patio, walkway, and driveway is built by our own team — start to finish — on a properly engineered foundation that won't shift, crack, or settle.

Twelve years in, our work still looks the day it was laid. That's the standard. That's the promise.

Hand-built by us

No sub-crews. The same team that quotes your project lays every paver.

Engineered to last

6" gravel base · geotextile fabric · polymeric joint sand. Every job. No shortcuts.

We answer the phone

Need us after install? Call. We'll pick up. That's how a family business works.

Our Promise

"If a paver settles or shifts on a job we built, we come back. No fine print. No fees."

— The M&L Team
WHY M&L

We don't cut what
holds it up.

Most paver failures happen below the surface. We don't shortcut the base — and we don't disappear after install.

01
Engineered Foundation

6" of compacted gravel base with geotextile fabric. The reason our work doesn't sink, shift, or split when winter hits.

02
Hand-Cut Precision

Every edge piece scored and cut on-site. No catalogue templates. No off-the-shelf bullnose. Every curve flows.

03
Workmanship Guarantee

If a paver settles or shifts, we come back. No fine print. No fees. Two-season minimum on every install.

HOW WE WORK

From first walk
to the final sweep.

01

Consultation

We walk your property, listen to how you live outside, and translate your vision into measurable design intent.

02

Design

Detailed material selection, pattern mockups, and a transparent quote — no surprises before we break ground.

03

Installation

Excavation, engineered base, precision laying, and finishing. Every step inspected, every joint compacted.

04

Lasting Beauty

We seal, polish, and walk you through care. Then we stand by it — long after the final paver is set.

"Three contractors quoted us. M&L was the only one who actually listened. The walkway looks like it grew out of the garden."
Michael Trent
Garden Walkway & Steps
"Two winters in and not a single paver has shifted. They know their craft. We'll be calling them for the pool deck next."

COMMON QUESTIONS

Got questions?
Real answers.

The questions we hear most from St. Louis homeowners before starting a paver, patio, or walkway project. Don't see yours? Call us — 636-849-6681.

Yes — every project starts with a free on-site consultation and a transparent written estimate. We walk your property, measure the space, discuss materials, and send you a detailed quote within 24 hours.

When installed on a proper engineered base — 30+ years easily. We use a 6" compacted gravel base with geotextile fabric, then polymeric joint sand. The pavers themselves can last a lifetime. The base is what fails on most jobs, which is why we don't cut corners there.

Most residential patios range from $15–$30 per square foot installed, depending on materials, layout complexity, and site prep. Premium materials and custom features (seating walls, fire pits, lighting) shift the price. We always give a transparent line-item quote — no surprises.

A typical patio or walkway takes 3–7 working days from excavation to final sweep. Larger or more complex projects (with retaining walls, fire features, or drainage work) can run 1–3 weeks. We give you a precise timeline before we break ground.

For most outdoor spaces — yes. Pavers won't crack, can be lifted and reset if needed, allow drainage (permeable options), and look premium for decades. Concrete is cheaper upfront but cracks within years, can't be repaired cleanly, and looks utilitarian. We install both, but recommend pavers 9 times out of 10.

Yes. Proper drainage is part of every install — pitched grades, drainage channels, and permeable joint options when needed. We also handle retaining walls, edge restraints, and any site prep required. One crew, one accountable team.

Yes — fully licensed and insured in Missouri. ICPI-certified installers. We're happy to share our insurance certificate on request. Family-owned and based locally since 2013.
