EM Construction provides professional window and door replacement and installation services for residential and commercial properties throughout New York and New Jersey. Our crews install energy-efficient windows and secure, well-fitted doors that improve comfort, reduce energy costs, and enhance the appearance of your property.
Windows and doors are your building’s primary interface with the exterior environment. Worn, single-pane, or poorly sealed windows allow heat and conditioned air to escape, drive up energy bills, permit outside noise to penetrate, and create condensation and moisture problems. Deteriorated or ill-fitting doors compromise security, comfort, and curb appeal. EM Construction replaces aging windows and doors with modern, energy-efficient units installed to manufacturer specifications for lasting performance.
Window Services
Window Replacement
We remove existing windows — including the frames and sill components where necessary — and install new double-hung, casement, awning, sliding, picture, or bay windows. All installations include proper flashing, insulation at the perimeter, and sealant at all joints to prevent air and water infiltration.
Energy-Efficient Window Installation
Modern windows with double or triple insulated glass units, low-E coatings, argon gas fill, and thermally broken frames dramatically reduce heat loss in winter and solar heat gain in summer. EM Construction specifies and installs windows that qualify for Energy Star certification and may be eligible for utility company rebates.
Historic & Landmark Window Replacement
Buildings in New York City landmark districts or on the National Register of Historic Places have restrictions on window replacement. We work with appropriate products and obtain the required approvals from the NYC Landmarks Preservation Commission (LPC) where applicable.
Commercial Window Installation
Large-scale commercial window replacements — storefronts, curtain wall units, and punched openings in commercial buildings — require specialized equipment and coordination with building operations. EM Construction manages commercial window projects with minimal disruption to building occupants.
Window Frame Repair
When the window unit itself is functional but the surrounding frame, sill, or trim is deteriorated, we repair or replace the affected components without replacing the entire window.
Window Guard Installation
New York City law requires window guards on all windows above the first floor in buildings where children under 10 reside. We install code-compliant window guards and provide the required annual maintenance and certification.
Door Services
Entry Door Replacement
A new entry door dramatically improves a building’s curb appeal, security, and energy performance. We install steel, fiberglass, and wood entry doors with proper weatherstripping, threshold, and door sweep installation to achieve a tight, draft-free seal.
Commercial Door Installation
Storefront glass doors, steel hollow metal doors, and aluminum-framed commercial entries are installed by our crews with proper frame alignment, hardware, and ADA-compliant hardware where required.
Interior Door Installation
Interior door replacement refreshes the look of any space. We install pre-hung interior doors — hollow core, solid core, fire-rated, and bi-fold configurations — with precision shimming, mortised hardware, and properly fitted trim.
Sliding & Pocket Door Installation
Sliding and pocket doors maximize usable floor area in tight spaces. We install both new and replacement sliding and pocket door systems with properly leveled track and smooth operation.
Door Hardware & Locksets
Upgrading door hardware — handles, locksets, deadbolts, closers, and hinges — improves security and function. We install residential and commercial grade hardware appropriate for each application.
Door Repair
Before recommending replacement, we assess whether a door can be repaired. Common repairs include planing swollen or binding doors, replacing worn weatherstripping, adjusting hinges, repairing damaged frames, and replacing failed glazing in glass-panel doors.
Storm Door Installation
Storm doors add a layer of insulation and weather protection to existing entry doors, extending their life and improving energy performance. We install full-view and half-view storm doors in aluminum and wood-composite frames.
