THINK BEYOND A SINGLE SURFACE
Expansive driveways, pool decks and outdoor living areas deserve preparation suited to their condition and finish.
Bring the driveway, patio and walkways into the same conversation. We’ll review the combined work, access and curing needs before agreeing on a plan.
Managers and community representatives can outline shared areas, multiple locations and owner or board requirements in our dedicated property-manager request.
CLEANING & SEALING SERVICES
We clean and seal stamped and decorative concrete for homes in Washington, D.C. and nearby communities. Before resealing, we check the surface and the existing finish.
Tell us about stains, faded areas or sealer that’s cloudy or peeling. We’ll explain the preparation needed and the finish you can expect.

MEET THE OWNER
I’m Edwin MacNamara, owner of DC Seals. Before we start, you’ll know what the job includes, what it costs and when to expect us. We’ll agree on what needs moving and explain when you can use the concrete again.
Start your project assessmentYOUR PROJECT, STEP BY STEP
We put the work and price in writing and confirm an arrival window. If the schedule changes, we let you know. Here’s what happens on the job.
We move furniture, planters and other agreed items out of the work area, then protect nearby surfaces and landscaping.
We clean the surface using a method suited to the concrete and existing sealer, then allow the drying time needed before sealing.
We agree on any repairs, their cost and the time they need before work starts. Repairs are completed and allowed to cure as needed before sealing.
We apply a high-quality, high-gloss sealer suited to your concrete, with a slip-resistant additive for added grip.
We confirm any extra time needed for repairs or drying, and keep you informed if weather changes the plan. After sealing, you receive completion photos and clear guidance on when to walk, drive or put furniture back.

CLEANING, FINISHES & CURING
We first check the condition of the existing sealer and whether it’s compatible with the product we plan to use. Send photos to start; we may need to inspect the surface before quoting.
Our sealing service uses a high-gloss sealer with a slip-resistant additive. The final sheen and texture depend on the surface and product, so we discuss the appearance with you before work begins.
Most cleaning and sealing jobs are planned for one working day. Repairs, drying and weather can affect the schedule. We explain the expected work time and how long to keep off the surface before you book.
That depends on the sealer, weather and surface conditions. We’ll tell you how long to keep people, vehicles and furniture off the concrete before we schedule the work.
Photos and approximate measurements help us assess the job. If we need to inspect the surface or existing sealer, we’ll arrange that before giving you a price.
