Middlesex County FAQs

Does coastal salt air affect epoxy and overlay longevity in towns like Old Saybrook or Westbrook?

Yes, salt spray and humid sea air are daily realities along the shoreline. We specify chloride‑resistant resins and UV‑stable topcoats for properties near Long Island Sound and along the lower Connecticut River. Occasional rinsing of your floor during winter and spring, combined with routine sweeping and mopping, will help keep the coating looking like new for years.

We’re near the Connecticut River—do we need moisture mitigation before coating?

Often yes. Homes and businesses in Middletown, Cromwell, Essex, and other river towns can sit over high water tables or older slabs without vapor barriers. Before any epoxy or resurfacing work, we test the concrete for moisture vapor emissions; if readings are elevated, we install a moisture vapor barrier to prevent bubbling or delamination.

Can you install coatings or resurfacing during colder months in Middlesex County?

Absolutely. Winter temperatures and nor’easters don’t slow us down. We use winter‑rated resins and set up portable heaters for unheated garages, basements, and workshops to ensure proper cure times. Our crews schedule installs around storms to keep your project on track.

Are permits required for epoxy coatings or concrete resurfacing?

Interior floor coatings generally do not require permits. However, if you plan to pour a new slab, expand a patio, or alter load‑bearing structures, you may need approval from your local building department. Requirements vary across Middlesex County; towns like Middletown, Old Saybrook, and Essex each have their own guidelines. We’ll help you determine whether a permit is needed and, if so, guide you through the process during your estimate.
