Quick answer
Egress window installation in New Jersey adds a code-compliant window large enough to climb out of — and for firefighters to climb in — so a basement room can legally be used as a bedroom. It involves cutting an opening in the foundation wall, installing the window, and building a window well with a proper drain tied to your drainage system so it doesn’t turn into a leak. RDC handles the cut, the window, the sealed well and the drainage together, inspects free, and warranties the work across New Jersey. Call (908) 569-1876.
Solutions
A legal, safe, and dry egress window — the whole job, done once
New Jersey’s building code is clear: any basement room used for sleeping needs an emergency escape and rescue opening — an egress window. It’s a life-safety requirement, not a formality, and it’s what makes a finished basement bedroom, in-law suite or legal rental count as real living space. But an egress well is also a hole dug against your foundation, so if the drainage isn’t done right it becomes one of the most common leak points in the house. RDC does the full job so you get both: code compliance and a dry basement.
After a free inspection, RDC delivers:
- Code-compliant egress window & opening: a window that meets New Jersey’s minimum clear opening, sill height and operability requirements so the room legally qualifies as a bedroom.
- Precise foundation cutting: the opening is cut cleanly in poured concrete or block with the header and framing detailed to keep the wall sound.
- Sealed, drained window well: a corrugated or terraced well anchored to the foundation with a well drain at the base — the detail that separates a dry well from a leaking one.
- Drainage tie-in: the well drain routed into a gravel bed or your interior drainage and sump so rainwater never pools against the glass.
- Waterproofed opening & well cover: the perimeter sealed and a clear, code-approved cover added to shed rain and leaves while still allowing escape.
If cutting the opening means working around structural cracks or a bowing wall, we address that first — see foundation repair. And because a below-grade well is a prime entry point for water, egress work and waterproofing belong together.
When you need one
Signs your New Jersey basement needs an egress window
Egress isn’t only about code — it’s about safety, light, and a well that stays dry.
Finishing a basement bedroom
NJ code requires an egress opening in any below-grade sleeping room — without one, the space can’t legally be a bedroom.
Adding an in-law suite or rental
A legal apartment or suite below grade needs a compliant escape and rescue window to pass inspection and be insurable.
Only tiny hopper windows
Old basements have small windows no adult can climb out of — a genuine safety gap in a fire or emergency.
Water pooling in an existing well
A window well that fills after rain and leaks at the frame usually has no drain — a common, fixable failure.
A dark, cave-like basement
A full egress window floods the space with daylight and ventilation, transforming how a finished basement feels and shows.
Selling or appraising the home
Egress-compliant bedrooms count toward finished square footage and bedroom count — real value at resale.
What to know
Why egress wells leak in New Jersey — and how we prevent it
An egress well is dug into the soil right against your foundation, which in New Jersey means dense clay that holds water and a high water table that keeps the ground wet. When a well is installed without a working drain, every nor’easter and spring thaw fills it like a bucket — and the water sits against the window until it finds a way in. Leaks trace to four avoidable mistakes:
- No well drain: the single most common cause — a well with nowhere for water to go becomes a reservoir against the glass.
- Drain not tied to drainage: a drain that dead-ends in clay instead of connecting to gravel or the sump backs up under pressure.
- Poor grading around the well: soil that slopes toward the well funnels surface water straight into it — see yard drainage.
- Unsealed opening & no cover: a gap where the well meets the foundation, or an open well collecting rain and debris, lets water in at the frame.
RDC installs the window and the water management as one job, so the well drains, the opening is sealed, and the grade sheds water away. Our reviewers regularly mention that we thought about the drainage the last contractor forgot — which is exactly why their well leaked.

Egress window questions
Frequently asked questions
Do I need an egress window for a basement bedroom in New Jersey?
Yes. New Jersey’s building code requires an emergency escape and rescue opening — an egress window — in any basement room used for sleeping. Without one, the room can’t legally be counted or permitted as a bedroom, and it’s a real safety issue in a fire. RDC confirms the exact requirement for your space on a free inspection.
How much does egress window installation cost in New Jersey?
A typical egress window with a properly drained well runs a few thousand dollars, depending on the foundation type, how much concrete has to be cut, and the well and drainage details. RDC gives a fixed, itemized quote after a free inspection so you know the full cost of the window, the cut and the drainage up front.
Will an egress window leak?
Not when it’s installed correctly. The most common cause of a leaking well is no drain — water fills the well and pushes in at the frame. RDC builds a well drain tied to gravel or your sump system, seals the opening, and grades the soil away, so rainwater has somewhere to go instead of pooling against the glass.
Do you need a permit to install an egress window?
Yes — cutting a foundation opening for an egress window requires a permit and inspection in New Jersey. As a licensed NJ contractor, RDC handles the permitting and makes sure the finished opening meets the clear-opening and sill-height requirements so it passes inspection the first time.
Can you cut an egress window into a concrete or block foundation?
Yes. We cut egress openings in both poured-concrete and concrete-block foundations, detailing the header and framing so the wall stays structurally sound. If we find a crack or a bowing wall while planning the opening, we address it first with foundation repair so the new window sits in a solid wall.
