Exterior door replacement is one of the most impactful and affordable home improvements available to NJ and PA homeowners. A new entry door can be installed in a single day, yet it immediately improves your home's security, energy efficiency, and curb appeal. Warner Exteriors installs entry doors, patio doors, and garage doors from ProVia and Therma-Tru — two of the most trusted door manufacturers in the industry — backed by a 10-year workmanship warranty on every installation.
Why Exterior Door Replacement Is Worth the Investment
Exterior doors take a beating in New Jersey and Southeast Pennsylvania's climate — summer heat and humidity, winter cold and wind, and the seasonal freeze-thaw cycles that stress seals, thresholds, and frames. Doors installed 15–20 years ago lack the modern multi-point locking, foam-core insulation, and weatherstripping technology available today.
A new exterior door delivers:
- Improved security with modern multi-point locking systems
- Better energy efficiency and significantly reduced air infiltration
- Enhanced curb appeal and first impression
- Increased home value and buyer appeal
- Better weatherstripping and threshold seals for NJ winters
- Manufacturer warranties ranging from limited lifetime to 25+ years
- Potential Energy Star tax credit eligibility

Fiberglass vs. Steel: Which Is Right for Your Home?
Both fiberglass and steel doors significantly outperform wood in energy efficiency, durability, and maintenance requirements. The right choice depends on your priorities and budget.
Fiberglass — our most-recommended option for NJ and PA:
- Won't rust, warp, or crack from NJ's humidity and temperature extremes
- Excellent insulating performance — foam-core construction
- Available in smooth or woodgrain finishes that can be painted or stained
- Dent-resistant — maintains appearance after minor impacts
- Higher upfront cost, but better long-term performance and lower maintenance
Steel — a strong, affordable option:
- More affordable than fiberglass
- Strong security performance
- Good energy efficiency with foam-core construction
- Can dent from impact and may rust if the finish is scratched — requires prompt touch-up in coastal or humid areas
Security Features to Look For in Your New Door
Modern exterior doors offer significantly stronger security than doors installed 15–20 years ago. What Warner Exteriors includes in every installation:
- Multi-point locking systems that secure at three or more points simultaneously
- Reinforced deadbolt strike plates with 3-inch screws into structural framing
- High-performance hinge pins that resist removal
- Proper jamb and frame installation with no air gaps
- Tight weatherstripping and threshold seals that prevent air and water infiltration
A quality door installed poorly provides poor security. Improper installation leaves gaps and weak points that compromise the door's performance. Our 10-year workmanship warranty covers our installation labor — so if there's ever an issue with how the door was installed, we'll fix it.
Frequently Asked Questions
How much does exterior door replacement cost in New Jersey?
Entry door replacement in NJ and PA typically ranges from $1,200–$3,500+ installed, depending on material (steel vs. fiberglass), panel style, glass configuration, hardware, and any sidelights or transoms. Patio doors range from $1,800–$4,500+ installed. Garage doors vary significantly based on size and style. We provide free, detailed estimates for all door projects.
Is fiberglass or steel better for NJ's climate?
For most NJ and PA homeowners, fiberglass is our recommendation. It won't rust in coastal humidity, won't warp from summer heat or freeze-thaw cycles, holds paint better, and provides better insulation than steel. Steel is a solid budget option for homes in less humid inland areas, but fiberglass delivers better long-term performance in the Delaware Valley region.
How long does door installation take?
A standard entry door replacement is typically completed in 3–5 hours. More complex installations — doors requiring new sidelights, transom windows, or frame modifications — may take a full day. Patio doors generally take 4–6 hours. We'll give you a realistic timeline when you schedule your estimate.
Can I replace just my door, or do I need to replace the frame too?
In many cases, only the door needs replacement if the existing frame and jamb are structurally sound. If the frame is warped, rotted, damaged, or if the rough opening has shifted, full frame replacement ensures a proper fit and seal. We inspect the existing frame during your estimate and recommend the most cost-effective approach.
Do ProVia and Therma-Tru doors come with warranties?
Yes. ProVia entry doors carry a limited lifetime warranty. Therma-Tru fiberglass doors also carry a limited lifetime warranty on the door slab and glass. Both manufacturer warranties apply only when installed by an authorized contractor — which Warner Exteriors is. We also back all installations with our own 10-year workmanship warranty.
