Rockville Centre is full of solid older homes on tree-lined streets: Colonials, Tudors, Capes and ranches that families love but often outgrow. Much of our work here is adding space and updating these houses, along with the emergency calls every older home eventually brings, like a burst pipe, a failed water heater, a roof leak or a kitchen fire.
On Reeve Road in Rockville Centre, we added a dormer to a shingled house and rebuilt its front at the same time. We framed the new roof and walls, sheathed and wrapped the house, and kept it closed up against the weather while the work went on.
The finished exterior pairs a new stone-faced front gable and stone base with white lap siding, tall black-framed windows, a metal awning over the front door and a new stone stoop. It looks like a new house on the same lot, with the extra space inside that the family needed.




Many Rockville Centre lots don't leave room to build out, so the smart way to add bedrooms and a real bathroom is often to build up. A dormer, or a full second floor, can turn a cramped Cape or ranch into a family-size house without giving up the yard. Because the work opens the roof, it has to be planned so the house is weathertight every night and the new framing ties properly into the old.
We handle the whole job: framing, roofing, windows, siding and stone on the outside, and insulation, electrical, plumbing and finishes on the inside. Projects that add a lot of space or cost can also need extra review from the Village, and we plan for that from the start so your schedule doesn't slip.
From a new second floor to a water emergency in the middle of the night, one local team handles the work and the paperwork, so you deal with one contractor from start to finish.
Rockville Centre is an incorporated village, so building permits come from the Village of Rockville Centre Building Department at 110 Maple Ave, not the Town of Hempstead. The Village has permit applications reviewed by an inspector before they are submitted, licenses its own electricians and plumbers, and requires contractors to carry insurance naming the Village. We take care of all of it.
Whether it's a dormer you've planned for years or water coming through the ceiling tonight, every Rockville Centre job follows the same clear steps.
