We recently hired Alpha Le Concrete to install a stamped concrete border around our entire barn, including under the porch overhang. From the first time I contacted Leo to the day his finished, my experience was truly fantastic. Leo is easy to work with. His prices are very reasonable. Once his crew began, they did not stop until the job was complete. They were on time every day and did a great job cleaning the site before they departed. Should we have any more jobs around the house, I will absolutely be calling Leo. We couldn't be happier!

I could not be happier with my stamped concrete patio built by Leo and his team. My old patio needed to be replaced and I contacted several contractors but Leo was quick to visit the site and came back with a fair price. They were able to start work within a week or two - now I can make the most out of patio season! Beautiful workmanship done by professionals.

Leo and his crew did an amazing job for my 2 concrete jobs! They poured 2 pads for me, 1st one was a 12x10 4 inch deep shed foundation and the 2nd one was a 15x25 6 inch deep patio. Both of them got done in one day and I'm very happy with the fast and professional worksmanship. Highly recommend Leo and his crew to anyone looking to do any kind of concrete projects!

Concrete sidewalk installation
What we pour

Sidewalks built to last decades.Not patched every few years.

A residential sidewalk takes more abuse than most surfaces on a property. Foot traffic, weather, tree roots from below, water from above. Poured wrong, it cracks and heaves in a few years. Poured right, it outlasts the home.

We pour new sidewalks along property lines, replace failing slabs, install ADA-compliant approaches where the sidewalk meets a driveway or entrance, and integrate sidewalks with landscaping and existing concrete. Each project starts with proper subgrade prep and ends with saw-cut control joints that direct cracking away from the visible surface.

Sidewalk types

Four sidewalk services. One standard.

New install

Property-Line Sidewalks

New concrete sidewalk along the property line, often connecting to existing public sidewalk. Standard widths (4-5 feet) and properly sloped for drainage.

Replacement

Sidewalk Replacement

Failing sidewalks are removed and replaced. Common when old slabs have heaved from tree roots, settled unevenly, or cracked beyond repair.

ADA-compliant

ADA Approaches

Where sidewalks meet driveways or entrances, ADA-compliant ramps and approaches. Proper slope, detection warning surfaces where required.

Integration

Connected Pours

Sidewalks integrated with patios, walkways, or driveways. We pour the seams smooth so the surfaces read as one.

Decorative

Stamped Sidewalks

Stamped pattern or color hardener for sidewalks that need to integrate with stone facades or landscape walls.

Repair

Section Replacement

When only a few sidewalk sections have failed, we replace just those sections and color-match the new concrete to the existing where possible.

Our process

From layout to last brush. Weather permitting.

01

Survey & layout

We measure the sidewalk path, check slope, look at existing concrete transitions, and confirm any ADA requirements.

02

Demo & prep

For replacements, old sidewalk is removed and hauled away. We grade the subgrade, compact it, and install a stable base.

03

Pour & finish

Forms set the edges, reinforcement laid per spec. Concrete poured and finished to a broom or smooth surface, depending on use.

04

Joints & cure

Saw-cut control joints placed by hand to control where cracks happen. We walk you through the cure window before foot traffic.

Why us for sidewalks

The work below the surface is what makes a sidewalk last.

01

Proper subgrade

Most failing sidewalks failed because the subgrade was rushed. We excavate to depth, compact properly, and install a stable base. Slab thickness alone doesn’t save bad prep.

02

Drainage built in

Sidewalks slope away from buildings and toward the natural watershed. No ponding, no slip hazards, no foundation seepage.

03

Hand-cut control joints

Saw-cut joints placed in strategic locations direct cracking out of sight, instead of random splits across the surface.

04

Fully insured & warrantied

1-year limited workmanship warranty on every new pour*.

Common questions

Concrete sidewalk questions. What homeowners ask first.

01 Do I need a permit for a sidewalk in Loudoun or Fairfax County?

Sidewalks that connect to public right-of-way may require a permit. Sidewalks entirely on private property usually don’t. HOAs may have additional requirements. We help navigate it on the estimate.

02 How long does a concrete sidewalk last?

30+ years with proper installation. The biggest enemies are bad subgrade and tree roots. We prep the base properly and recommend root barriers where appropriate.

03 Will my sidewalk crack?

There’s a saying in the concrete trade: there are two types of concrete, concrete that has cracked, and concrete that hasn’t cracked yet. All concrete cracks eventually. Our job is to control where: we compact the base properly, reinforce the slab, and place control joints by hand so cracks happen on planned lines instead of random splits. Our 1-year limited workmanship warranty covers structural cracks that meet the size/length thresholds, see full warranty terms.

04 Can you replace just one section of sidewalk?

Yes. Sidewalks are typically poured in sections (slabs), and individual sections can be removed and replaced if they’re the only ones failing. We try to color-match the new concrete to the existing.

05 How much does a sidewalk cost in Northern Virginia?

Cost depends on length, width, access, and whether you’re replacing existing or pouring new. We give a real number after a quick site walk or based on photos and dimensions.
