Concrete Preparation & Repair Services in Southern New Hampshire
Proper surface preparation is the foundation of any long-lasting concrete or epoxy flooring project. Sealed C&E provides professional concrete prep and repair services for homeowners across Southern New Hampshire, ensuring every floor is strong, smooth, and ready for a high-quality finish. Whether you're planning to install epoxy flooring, refresh an existing concrete surface, or remove old materials, proper preparation is essential for durable results.
Why Concrete Preparation Matters
A concrete surface is only as strong as the foundation beneath it. Without proper prep, coatings may peel, adhesives may fail, and cracks can continue to spread. Professional preparation ensures the surface is structurally sound, moisture-tested, and ready to bond with a new finish.
Strong Foundation
Proper preparation strengthens the concrete surface, ensuring it’s structurally sound, level, and ready to support a long-lasting finish.
Prevents Moisture Problems
Moisture testing and surface prep help prevent issues like bubbling, peeling, and mold-related damage—especially important in Southern NH basements and garages.
Better Performance
Grinding and repairs create a clean, receptive surface so coatings bond correctly, reducing the risk of lifting, peeling, and premature wear.
Smooth, Even Final Surface
Prep eliminates cracks, rough spots, old residue, and imperfections, resulting in a smooth, durable floor that looks better and performs longer.

FAQs About Concrete Preparation
Concrete preparation ensures the surface is clean, level, and structurally sound so coatings bond correctly. Without proper prep, floors can peel, bubble, or fail prematurely—especially in New England’s moisture-heavy climate.
Most projects involve mechanical grinding, crack repair, adhesive removal (if needed), moisture testing, and general surface cleaning. The exact steps depend on the condition and age of the concrete.
Yes. Cracks must be repaired to prevent them from spreading and to ensure a smooth, even finish. Proper crack repair also helps coatings apply evenly and last longer.
Absolutely. Old coatings and adhesives can block proper adhesion. Mechanical grinding removes these layers and exposes clean concrete so new coatings bond securely.
Basements, garages, and older concrete slabs in Southern NH often experience moisture issues. If there are signs of dampness, discoloration, or previous coating failure, moisture testing is recommended before installation.
Most do. Grinding removes surface weaknesses, opens the pores of the concrete, and helps coatings soak in instead of sitting on top—reducing the risk of peeling or lifting.
Most residential prep projects take a few hours to a full day, depending on the size of the space and the amount of repair work needed.
Yes. Mechanical grinding and repair can be completed safely indoors using dust-controlled equipment designed for enclosed spaces.
No. Professional grinding equipment includes dust collection systems that keep the workspace clean and minimize airborne dust.
Yes. Proper prep improves the look, safety, and longevity of bare concrete. It also prevents further deterioration and makes future coatings easier and more effective.
