What Our Clients Say
Real feedback from homeowners in Connecticut and New York who trusted JEF General Contracting with their projects.
JEF replaced our entire roof after storm damage and did a fantastic job. The crew was professional, cleaned up every day, and finished ahead of schedule. No pressure, no upsell.
We hired JEF for a full kitchen remodel and could not be happier. Jose Luis walked us through every step. One crew handled everything — no strangers in the house every week.
Called JEF for a chimney leak that two other contractors could not fix. They found the source in 20 minutes and had it waterproofed the same week. Straight answer, fair price.
New composite deck, siding replacement, and gutters all done by the same team in one season. JEF coordinated everything and kept us updated the whole way through.
Got three estimates. JEF was not the cheapest but they were the only ones who actually walked the roof and explained what needed to be done. Three years later, zero issues.
