Smooth and Protect Concrete That Lasts

Concrete grinding and sealing services for commercial and residential properties in Everett, Washington and the Greater Seattle region.

Your concrete floors show every crack, every uneven patch, and every stain that comes from years of use in a damp climate. In Everett, Lynnwood, Seattle, and surrounding areas, where moisture seeps into unsealed surfaces and causes dusting, breakdown, and discoloration, untreated concrete becomes harder to clean and less safe to walk on. Rough spots catch debris, and the surface never looks as clean as it should.


Sorin's Janitorial provides concrete grinding to level and smooth surfaces, followed by sealing that protects against moisture, staining, and surface wear. This process works for garages, warehouses, walkways, and commercial floors where durability and appearance both matter. Grinding removes old coatings, lippage, and imperfections, while sealing creates a protective barrier that helps the surface resist the damp conditions common across Everett and the Pacific Northwest.

How Grinding and Sealing Improve Your Concrete

Grinding starts with industrial equipment that levels the surface and removes old coatings, adhesive residue, or rough spots. In Everett and the surrounding areas, where moisture impacts concrete over time, this step prepares the surface to accept a sealer that actually bonds. Once the concrete is smooth and clean, a protective coating is applied to guard against water penetration, staining, and dusting.


After the work is complete, you will notice a cleaner, more uniform surface that is easier to sweep and maintain. The sealed concrete resists moisture absorption, which means less dusting, fewer stains, and a finish that holds up better under foot traffic and equipment use.


Sorin's Janitorial uses surface prep techniques and coatings suited to the specific use of your space, whether that is a warehouse floor, a residential garage, or a commercial walkway. The service does not repair structural damage or deep cracks, but it does make usable concrete more durable and easier to keep clean. Drying time varies depending on the sealer used and environmental conditions.

Questions come up when planning concrete work

Clients typically ask about timing, surface preparation, and how long the sealer will last. These are the most common questions before scheduling concrete grinding and sealing.

What does concrete grinding actually do?
Grinding levels the surface, removes old coatings, and smooths out rough patches or lippage. It prepares the concrete so the sealer can bond properly and last longer.
How long does the sealer take to dry?
Most sealers allow light foot traffic within a few hours and full use within 24 to 48 hours. Cure time depends on temperature, humidity, and the product used.
Will sealing prevent all staining and moisture damage?
Sealing greatly reduces staining and moisture penetration, but it is not completely stain-proof. Prompt cleanup of spills and regular maintenance will keep the surface looking its best.
What types of concrete can be ground and sealed?

This service works on most interior and exterior concrete slabs, including garage floors, warehouse surfaces, and walkways. Sorin's Janitorial evaluates the condition during the assessment to confirm suitability.

How often does concrete need to be resealed?
Resealing frequency depends on traffic and exposure, but most sealed concrete in Everett benefits from reapplication every three to five years. High-use areas may need it sooner.
