Window & Door Services

Replacement Windows

Replacement windows are one of the best upgrades you can make to an older New Jersey home. Precision General Construction removes your existing windows and installs new, energy-efficient units that fit precisely into the existing openings. No exterior trim or siding modification is needed for a standard replacement, which keeps the project clean and cost-effective. We install replacement windows from leading manufacturers, including Andersen, Pella, Marvin, and several other quality brands. Each window is measured individually to ensure a perfect fit. Our installers seal every unit with proper insulation and weatherstripping to eliminate drafts and moisture infiltration. We install every major window style: double-hung, casement, awning, sliding, bay, bow, picture, and specialty shapes. Material options include vinyl, fiberglass, wood, and aluminum-clad wood. We bring samples to your home and help you choose the right combination for each opening.

Entry Doors & Storm Doors

Your entry door is one of the first things visitors notice and one of the most important barriers protecting your home from weather and intruders. Precision installs fiberglass, steel, and wood entry doors that combine security, energy efficiency, and curb appeal. Fiberglass doors resist denting, warping, and rotting while offering the look of real wood. Steel doors provide the strongest security at an affordable price. Solid wood doors deliver a classic, high-end appearance. We also install storm doors that add an extra layer of protection and insulation to your entry. Storm doors extend the life of your primary door, improve energy efficiency, and let you enjoy ventilation through a screen in warmer months. Every entry door installation includes proper weatherstripping, threshold sealing, and hardware installation. We ensure the door is plumb, level, and operates smoothly. If your existing door frame is damaged or out of square, we repair or rebuild it before installing the new door.

Sliding & Patio Doors

Sliding patio doors and French doors connect your indoor living space to your deck, patio, or backyard. Precision installs sliding glass doors, French doors, and multi-panel folding door systems from top manufacturers. Modern patio doors feature large glass panels that flood your home with natural light while providing excellent insulation and smooth, easy operation. Options include two-panel sliders, three-panel configurations, and wide-opening folding systems that blur the line between indoor and outdoor living. All patio doors we install feature multi-point locking systems for security and dual-pane or triple-pane glass for energy efficiency. If you are adding a new deck or renovating your kitchen or living room, a new patio door can transform how you use the space. We coordinate door installation with other projects for a seamless result.

Energy Efficiency & Professional Installation

Old, single-pane windows and poorly sealed doors are among the biggest sources of energy loss in New Jersey homes. Replacing them with modern double-pane or triple-pane windows with Low-E coatings and argon gas fills, along with properly insulated doors, makes an immediate difference in comfort and utility costs. Precision's installation crews are experienced, trained, and meticulous. We remove old windows and doors carefully, prepare each opening properly, and install every unit level and plumb with proper insulation and flashing. Our installations are clean and efficient. We protect your floors and furniture, remove all debris, and leave your home in better shape than we found it. After installation, we test every window and door to ensure smooth operation and proper locking. We review maintenance and care with you and make sure you are completely satisfied.
