Testimonials
Mike and his crew were very professional, and they made my old pool patio look like new again. I was going to rip it up and put a new one in, but I'm glad I called Mike. His price was very reasonable, and he is very responsive! He is at your job and will make sure that you are satisfied with the work before leaving. I highly recommend Mike and his team! Here are the before and after photos. The surface is new again!

New London County FAQs

Will salt air from Long Island Sound or winter road salt hurt my coating?

New London County’s shoreline towns — New London, Groton, Stonington, East Lyme, Waterford, Old Lyme — are exposed to salty sea mist year‑round, while snowstorms lead to heavy de‑icing on I‑95 and local roads. Our coatings use chloride‑resistant resins and UV‑stable topcoats engineered to withstand both salt spray and road chemicals. A quick rinse during late winter and spring helps wash away residue, keeping your floors looking great.

Do basements near the Thames River, Niantic River, or the coast need moisture mitigation?

They often do. Many homes and businesses along the Thames and in marshy areas — including New London, Groton, Norwich, and Old Lyme — sit over high water tables or have older slabs without vapor barriers. Before applying epoxy or overlays, we test every slab for moisture vapor emissions. If readings are high, we install a moisture vapor barrier to prevent bubbling or peeling and ensure long‑lasting adhesion.

Can you install coatings and resurfacing during colder months in New London County?

Yes. While winters near the coast can be windy and damp, we work year‑round. We schedule projects around nor’easters or cold snaps and use winter‑rated resins along with portable heaters for unheated garages, basements, and shops. This allows us to maintain proper cure times even when temperatures drop.

Do coatings or resurfacing require permits?

Interior floor coatings typically do not require permits. However, if you’re adding a new slab, extending a deck, or making structural changes, you may need approval from your local building department. Municipalities like New London, Groton, and Norwich each have their own rules. During your estimate, we’ll review whether a permit is necessary and guide you through the process if needed.
