About Gappsi, Inc.

The business serves homeowners throughout Smithtown and surrounding Long Island communities, operating Monday through Saturday from 9 AM to 4 PM. Customers can reach the office at (631) 543-1177. The company specializes in outdoor construction projects including paver installation, pool construction, and recreational facility building.
What distinguishes Gappsi from typical contractors is their work on specialized recreational installations. One review details their construction of two bocce courts for a senior living community of 185 homes, where they tailored the design to accommodate over 100 summer league players while ensuring durability for year-round weather. Their portfolio also includes paver restoration work where they corrected deficiencies left by previous contractors, completing resealing projects within a two-day timeline.
Customers consistently mention specific team members in their feedback. One reviewer described working with Sefa on the pool end of a project and Joe for yard restoration, noting both were polite and professional. Another customer highlighted Giuseppe's responsiveness, stating the phone was answered on the first ring after a single call. A senior living community review praised the follow-up from Giuseppe and his team, noting they quickly addressed remaining small issues after completing the bocce court project.
