Concrete Repair & Maintenance - We Fix Cracks & More

Protect. Restore. Maintain.

The SUNDEK of Washington Concrete Maintenance Division provides reliable, year-round care for interior and exterior concrete surfaces, with specialized expertise in protecting against the harsh freeze-thaw cycles and salt exposure common in the Mid-Atlantic.

From cleaning, sealing, and polishing to surface repairs and winter damage prevention, our team helps homeowners and businesses protect their investment, extend the life of their surfaces, and maintain long-term performance—season after season.

What kind of concrete repair can SUNDEK of Washington do?

We work with cracked concrete, spalling, chipping, fading, or any other type of damage. With more than 30 years of working with concrete, there’s nothing we haven’t seen!

When should I fix my damaged concrete?

It’s critical to fix damaged concrete as soon as possible because the longer you let it sit, the worse it gets. Especially in our area of the country where we get rain and freezing temperatures, weather can cause even more problems on a damaged surface.

What does SUNDEK of Washington do with damaged concrete?

After years of experience, we’ve seen it all when it comes to concrete. Generally, here’s how we approach a damaged surface:

Assess the damage. Our experienced contractors can identify the cause of the damage and help create a plan to prevent it from occurring again.
Resolve the problem spots.
Determine necessary steps to help the area blend in with the rest of your concrete surface. There are many ways to do this. We can use color, texturing, and other techniques to make the previously troubled spot blend in seamlessly with its surroundings.
With resurfacing we can apply a coating and do stamping or staining to give you a surface that looks brand new. If your surface had cracks, we can incorporate them into a new design with custom scorelines.
Seal the surface. This step will protect your concrete and help prevent future damage (read more about the importance of sealers).

Can I repair damaged concrete myself?

Although it is possible to repair concrete yourself, we don’t recommend it. Experienced and trained contractors such as the installers at SUNDEK of Washington have years of experience working with concrete. Working with a professional is ideal so that you don’t inadvertently make things worse.

Concrete maintenance services

Regular maintenance is one of the best ways to protect your concrete investment. In our area, where freeze-thaw cycles, road salts, and year-round moisture are a fact of life, unprotected surfaces don't just look bad—they break down faster than they should.

At SUNDEK of Washington, we provide complete maintenance services for both residential and commercial properties. Whether you're looking to keep your driveway in top shape or maintain a large commercial space, we can help with:

Deep cleaning to remove dirt, mildew, stains, and buildup that dull your surface and trap moisture
Concrete sealing to create a protective barrier against moisture, salt, chemicals, and everyday wear
Surface re-coloring or refreshing for decorative concrete that's faded over time
Polishing for interior floors that need renewed shine and durability
Preventative inspections to catch small issues early—before they turn into expensive repairs

How often should concrete be maintained?

It depends on your specific surface, but here's what we typically recommend: most exterior concrete should be cleaned once a year and sealed every 2 to 3 years. High-traffic areas or commercial surfaces may need more frequent attention.

If you're not sure what your concrete needs, we're happy to take a look and give you our honest assessment. After 30 years of working with concrete in the Mid-Atlantic, we can tell you exactly what will help your surface last.

A Beautiful Space for Residents to Enjoy

At The Arrive in Alexandria, VA, we resurfaced more than 34,000 square feet—transforming it into beautiful walkways, stairways, and an outdoor experience area. Part of the challenge was one section of the project: a rooftop with major cracks and damage that was causing leaks into the parking structure below. See how we addressed the surface with waterproofing, creating a beautiful space for residents to enjoy.
