Change What Does Not Work Inside Your Home

Interior remodeling and general construction services in Manhattan, Brooklyn, Queens, The Bronx, Staten Island and Long Island

Rooms in your home that no longer fit how you live can be rebuilt to serve a different purpose. A basement that floods every spring can be waterproofed and finished. A kitchen with cabinets that do not close properly can be reframed and refitted. When walls are cracked, floors are uneven, or plumbing runs through spaces where you want storage, you need someone who can open the walls, fix the structure, and rebuild the space so it works.


Gemz Construction provides interior remodeling and general construction services for homeowners throughout Manhattan, Brooklyn, Queens, The Bronx, Staten Island and Long Island who need more than surface updates. We handle structural repairs, room additions, bathroom and kitchen remodels, drywall installation, flooring replacement, and finish carpentry. Our work includes fixing framing that has shifted, replacing subflooring damaged by leaks, and rebuilding interiors after water damage or long-term neglect.


If your home needs interior repairs or remodeling, contact us to discuss what needs to change and how we can rebuild it.

How interior work differs from surface renovation

Interior construction starts with assessing what is behind the walls and under the floors. We check for framing damage, moisture issues, outdated wiring, and plumbing that may interfere with the new layout. If studs are rotted or joists are sagging, we replace them before installing new drywall or flooring. If the subfloor is soft or stained, we remove the damaged section, dry the area, and install new plywood before laying finish flooring.


After construction, you will have walls that are plumb and square, floors that do not bounce or creak, and finishes that fit tightly without gaps. Doors will close without sticking, and cabinets will sit level without needing shims. If you had a leak or water damage, the rebuilt area will match the rest of the room without visible repairs.


We coordinate with electricians and plumbers when remodeling requires moving outlets, running new lines, or relocating fixtures. We install drywall, tape and mud seams, sand surfaces smooth, and prime walls before painting. Finish work includes installing trim, baseboards, and door casings that align with existing details or match new design plans. We do not start finish work until all structural and moisture issues are resolved.

What people need to know before remodeling

Homeowners in Manhattan, Brooklyn, Queens, The Bronx, Staten Island and Long Island often ask how long remodeling takes, whether they need to move out during construction, and what happens if we find hidden damage once walls are opened. These questions reflect real concerns about disruption, cost, and the condition of older homes.

How long does a typical remodel take?
A bathroom remodel usually takes two to three weeks, while a kitchen remodel takes four to six weeks depending on the scope of work. Larger projects or those requiring structural repairs take longer.
What if you find mold or rot behind the walls?
We remove the damaged material, treat the area to prevent further growth, and replace framing or insulation as needed. We document the damage and provide a revised estimate before proceeding with additional repairs.
Do I need to move out during construction?
Most homeowners stay in the house during remodeling, but you may lose access to certain rooms or utilities for a few days. We set up temporary barriers and coordinate work to minimize disruption.
Can you match existing finishes in older homes?
We match trim profiles, flooring styles, and paint colors as closely as possible. If exact matches are not available, we blend new finishes with existing ones so the transition is not obvious.
What is included in general construction services?
General construction includes framing, drywall, flooring, trim work, and structural repairs. We handle the rebuilding side of projects, and we coordinate with licensed tradespeople for electrical, plumbing, and HVAC work when needed.
