Concrete Garage Floor Repair & Resurfacing in the D.C. Area

Learn about garage floor repair and how SUNDEK of Washington can help resurface your concrete.

Garage floors take on a lot more than most surfaces in a home—from the constant weight of vehicles to spills, moisture, and everyday wear and tear. That’s why choosing a high-quality garage floor repair contractor matters. We’ll help protect the concrete beneath while creating a surface that’s built to last. With the right contractor, a garage floor can be both tough and visually appealing, proving that this space doesn’t have to be dull or purely utilitarian.

SUNDEK coated this residential garage floor in Virginia Beach, VA, with an epoxy flake coating system.

Repair, Resurfacing, or Replacement: What’s Right for Your Garage Floor?

The right solution depends on the condition of your concrete slab.

  • Repair: Best for surface-level issues such as small cracks, chipping, spalling, or uneven areas that can be corrected with patching or leveling.
  • Resurfacing: A good option when the slab is structurally sound but worn, discolored, or dated. A new coating or overlay restores appearance and helps protect the concrete long term.
  • Replacement: Typically needed when the slab has major structural problems, large or shifting cracks, or ongoing issues related to settlement or drainage that cannot be corrected with surface repairs. (We see very few garages requiring concrete replacement.)

Pro tip: Often, the best results come from repairing the concrete and resurfacing it together. Filling cracks or patching alone can leave noticeable mismatches, but an overlay or coating helps tie the surface together visually.

Repaired cracks often standout from the rest of the garage floor.

Best Repair Options for Your Garage Floor

When it comes to choosing a system for repairing your garage floor, the best option depends on what you’re personally looking to get out of your flooring. Here, we’ll take a closer look at the garage floor solutions SUNDEK of Washington offers and how they combine durability, style, and expert installation.

Filling cracks and patching

Cracks, chips, and surface damage are common in garage floors and should be addressed first. At SUNDEK of Washington, we assess the type and extent of damage to determine the right repair approach. Minor cracks and surface imperfections can often be filled and patched, while more significant issues may require additional preparation before any finishing system is applied.

Basic clear seal

Sealing your garage floor is a great option for homeowners who are happy with the look of their existing concrete floor and simply want to protect it. This type of sealer creates a barrier that helps guard against stains, moisture intrusion, and everyday wear. Sealing concrete is an effective, low-maintenance way to extend the life of the floor while keeping its original character intact.

Epoxy coatings

Epoxy garage floor coatings are a durable option for garage floors and are typically applied after repairs are complete. SUNDEK of Washington offers several epoxy systems, depending on the look and performance you want.

  • Epoxy flake systems: A multi-layer system that adds color, texture, and durability while helping disguise minor surface imperfections.
  • Solid, non-flake epoxy: Provides the same durability as flake systems with a smoother, more uniform appearance and a lower overall cost.
  • Metallic epoxy: A decorative option that creates a smooth, glass-like finish with subtle shimmer or bold visual movement.

Pro tip: “We provide a combination of Polyurea for the base coat, giving the surface a moisture block which is so important,” says Bob Miller, Vice President and General Manager at SUNDEK of Washington.

SunBurn system

With our SunBurn Burnishable Stain System, we can offer a durable and versatile way to add long-lasting color to concrete surfaces. Because SunBurn chemically bonds with the concrete to color and harden it, it creates a finish that won’t flake, peel, or wash out over time. This system is available in a wide range of colors and can be applied in either a translucent or opaque finish. In addition to its durability and customization options, SunBurn is low-VOC, environmentally friendly, and has very little odor, making it a practical and appealing choice for many spaces.

Acrylic, non-slip floor

We can apply our acrylic systems over your bare concrete garage floor, giving it a fresh new look. We have standard colors available, but customers can also request custom colors. With our acrylic systems, we can combine other decorative techniques such as scorelines or patterns to create the look you desire for your garage floor surface.

Custom logos

A custom logo on a garage floor adds a polished, professional look while showcasing personality. We can incorporate a desired logo or custom design into your space while still maintaining the durability of the entire garage floor surface.

Frequently Asked Questions

See answers to some common questions we get about garage floor repair.

What causes cracks and surface damage in garage floors?

Garage floor cracks and surface damage can develop for several reasons, including moisture intrusion, temperature changes, heavy vehicle loads, and natural settling of the concrete. Over time, these factors can lead to cracking, chipping, spalling, or uneven areas, especially in older slabs or garages that see frequent use.

Do garage floor cracks always mean structural problems?

No. Many garage floor cracks are surface-level and do not indicate a structural issue. Hairline cracks and minor surface damage are common and can often be addressed with proper repair and resurfacing. Larger or shifting cracks may point to underlying problems and should be evaluated by an experienced contractor.

Can I apply epoxy to my garage floor myself?

There’s really no quick or simple DIY epoxy garage floor project. Proper application of epoxy or polyaspartic coatings requires careful surface preparation, precise mixing, and close attention to detail for long-lasting results. For best results, we recommend hiring an experienced professional. If you choose to do it yourself, be sure to follow a detailed, step-by-step guide closely.

What’s the difference between epoxy paint and an epoxy coating?

There’s often confusion between epoxy paint and epoxy coatings. While the names sound similar, they perform very differently. Epoxy paint contains only a small amount of epoxy and wears like paint, while an epoxy coating bonds to the concrete to create a durable, long-lasting protective surface.

We can even give you a retro checkerboard design like we did in this garage.

Can I add a design to my garage floor?

Yes—garage floors can be customized with a wide variety of design options across many decorative concrete systems. From solid colors to metallic effects, decorative aggregates, textured finishes, and high-gloss surfaces, there are plenty of ways to create a look that fits your style and needs. Looking at photos of finished garage floors is a great way to get inspiration and see what’s possible. See photos of some garage floors we’ve resurfaced here.

Are garage floor coatings slippery?

Garage floors don’t have to be slippery. A reputable contractor will add slip-resistant materials to improve traction, which is especially important in a space exposed to moisture and vehicle traffic. With the right system, a garage floor can be both durable and safe.
