Professional Door Replacement From a Trusted General Contractor
RJ Exteriors is an exterior home improvement company built on traditional craftsmanship and dependable communication. Exterior door installation is a natural extension of the siding, window, and remodeling work we've done for homeowners across Chester, Delaware, and Montgomery counties.
We treat every door project, from a front entry upgrade to a full patio slider replacement, with the same attention we give larger home exterior renovation work. That means accurate measurements, proper flashing and weatherproofing, and a finished product that fits tight and operates smoothly for years.
As a general contractor with in-house project management, we coordinate door installation alongside siding, trim, and window work. When homeowners tackle a broader exterior remodeling project, everything gets scheduled and installed as one cohesive plan rather than a series of disconnected visits.

Why Homeowners Choose Professional Door Replacement
A poorly installed door leads to drafts, water intrusion, and premature wear, even when the door itself is high quality. Correct installation is what actually protects the investment.

- Improved energy efficiency and reduced drafts around entry points
- Better home security with properly reinforced frames and hardware
- Enhanced curb appeal with styles that match the home's architecture
- Elimination of sticking, warping, and gaps common with aging doors
- Proper flashing and sealing to prevent moisture damage
- Increased resale value as part of a broader exterior renovation

Exterior Door Installation Questions From Local Homeowners

How long does exterior door installation typically take?
Most single door replacements are completed in a single day. Projects involving multiple doors, structural repairs, or coordination with siding or trim work may take longer, and we'll give you a clear timeline before work begins.
What types of exterior doors do you install?
We install entry doors, storm doors, French doors, and sliding patio doors in wood, fiberglass, and steel. We'll help you choose a material and style that fits your home's architecture and your maintenance preferences.
Will a new exterior door actually improve energy efficiency?
Yes, when it's installed correctly. Gaps around an old or poorly fitted door are a common source of drafts. Proper flashing, weatherstripping, and insulation during installation make a measurable difference in comfort and energy costs.
Can you replace a door as part of a larger exterior renovation?
Absolutely. As a full-service exterior remodeling contractor, we regularly combine door replacement with siding installation, window replacement, or porch additions so the whole project is scheduled and finished together.
Do you handle rotted or damaged door framing?
Yes. During removal, we inspect the surrounding framing for water damage or rot. If we find hidden issues, we'll walk you through the repair options before installing the new door so the final result is solid and long-lasting.
