Concrete ceilings in post-war apartments are an obstacle to installing modern lighting. Wiring and lighting recesses cannot be buried in concrete without compromising the building's structure. Renaissance Renovations specializes in retrofitting modern lighting into apartments with concrete ceilings through the installation of a real, seamless, low-profile drywall ceiling with low profile recessed lighting. This height reduction is imperceptible — approximately 2 inches — and the tradeoff is high quality light in previously cavernous apartments.
