The Possibilities
What Your Exterior Remodel Can Include
Some projects refresh a single surface. Others rethink the whole envelope. Here is what our New Jersey clients most often take on.
Siding, Trim & Curb Appeal
New siding transforms a home’s face and its weather protection at once. We install clapboard, shake, and fiber cement with the trim details that give a facade real character.
Windows & Doors
Replacement windows and doors cut drafts, quiet the house, and sharpen its look. We handle sizing, flashing, and trim so everything performs as well as it photographs.
Porches & Front Entries
A rebuilt portico or covered entry changes how the whole house greets the street. We design entries that fit your home’s architecture, not a catalog.
Decks & Patios
From new decks with clean rail lines to bluestone patios, we build the outdoor rooms where summer actually happens.
Sunrooms & Outdoor Living
Three-season rooms, screened porches, and sunrooms blur the line between inside and out, adding light-filled space you will use most of the year.
Exterior Additions & Expansions
When the outside changes because the inside grew, we handle both. Additions, dormers, and bump-outs designed and built as one seamless project.
The Case for the Envelope
Why Remodel Your Exterior?
An exterior remodel is the rare project that pays you three ways: curb appeal, comfort, and protection.
Curb Appeal That Pays
Siding, windows, and a strong entry are the first things buyers and neighbors see. Exterior projects consistently rank among the highest-ROI remodels a New Jersey home can get.
Weather Protection First
Every exterior remodel starts with the envelope: flashing, drainage, and materials installed to keep water out for decades, not just past the warranty.
Lower Energy Bills
Modern windows, doors, insulation, and air sealing cut heating and cooling costs year round while making every room more comfortable to sit in.
One Team for the Whole Envelope
Siding, roofing lines, windows, and trim all meet each other. Design-build means one team detailing those intersections instead of three subcontractors pointing fingers.
Our Methodology
The Design-Build Advantage
Exterior projects are where multi-contractor chaos shows up fastest. A siding crew, a window installer, and a deck builder each do their piece, and the seams between them are exactly where leaks, gaps, and mismatched details live. Homeowners end up refereeing trades that do not share a plan or a P&L.
Design-build solves that problem. We put design, engineering, and construction under a single roof. Because our architects, designers, project managers, and carpenters all work for the same firm, every flashing detail, trim intersection, and material transition is decided in the design phase and built by one accountable team.
1%
Contingency Cap on Final Price
The difference shows up in the numbers. Hofmann Design Build projects carry a contingency fund of only 1% of the final price. That is a fraction of industry norms. Why? Because our integrated process eliminates the surprises that drive cost overruns elsewhere. For any homeowner comparing exterior remodel contractors in NJ, design-build is the safer path. One accountable team. Concept to completion.
★★★★★
“We worked with this group in 2015 to redo our whole home. They were very professional and came in on time and within budget. Our home went from a typical cape cod to an open floor plan modern home with Craftsman touches. We liked it so much that we wanted to use them for a second home renovation.”

From Sketch to Walkthrough
Our Design-Build Remodeling Process
Every Hofmann exterior remodel follows the same proven seven-step path. The depth of each step scales to your project, but the structure stays consistent.
01
Initial Assessment & Discovery
First, we meet at your home anywhere across our four-county New Jersey service area. We walk the space together, listen to your goals, and take precise measurements. As a result, you leave with a clear understanding of what is possible.
02
Schematic Design & Preliminary Estimate
Our designers produce visual concepts and a preliminary estimate so you can budget-check the project before any final commitments.
03
Final Design & Material Selections
We refine the design into construction-ready drawings and guide you through cabinetry, finishes, fixtures, and materials, all coordinated for cohesion.
04
Permits & Documentation
We handle permits, zoning approvals, and regulatory paperwork with your municipality, so you never have to.
05
Procurement & Pre-Construction
Materials are ordered, the construction package is finalized, and the build team is briefed before a single tool comes out.
06
Construction
Our project managers and craftspeople execute the build with respect for your home, your schedule, and the quality standards that have defined Hofmann for over 40 years.
07
Final Walkthrough & Warranty
Finally, we walk the finished space with you. We address any final details. Moreover, we stand behind the work long after the last invoice clears.

Common Questions
Frequently Asked Questions
How much does an exterior remodel cost in New Jersey?
It depends on scope. Replacing siding on a typical NJ home generally runs $40,000 to $90,000 depending on material, while a full exterior transformation with siding, windows, a new entry, and a deck or porch ranges from $100,000 to $250,000+. We provide a preliminary estimate after the schematic design phase, and our 1% contingency cap means the number you approve is the number you pay.
How long does exterior remodeling take?
Most exterior projects run 6 to 12 weeks of construction depending on scope and season. Because nearly all of the work happens outside, your daily life indoors continues largely undisturbed. We give you a realistic timeline before construction begins, and we hit it.
Can you do siding, windows, and a deck as one project?
Yes, and it is usually the smartest way to do it. Combining envelope work means one mobilization, one design that coordinates every material and color decision, and details like flashing and trim that are engineered to work together rather than patched where trades meet.
What siding materials do you work with?
Fiber cement, cedar clapboard and shake, and premium composite lines are our most common recommendations for New Jersey homes. During design we walk you through durability, maintenance, and cost tradeoffs so the material fits both the architecture and your budget.
Do I need permits for exterior work in NJ?
Most structural exterior work does: decks, porches, additions, and many window and door changes. We handle all permits, inspections, and code compliance with your municipality, so you never have to.
Can you match an addition to my existing exterior?
Yes. Because our architects and builders work as one team, additions and dormers are designed to look original to the house, with rooflines, siding, and trim that blend rather than announce themselves.
Where do I start if I am not sure what my exterior needs?
That is exactly what the Project Discovery Call is for. We walk the outside of your home with you, talk through what is cosmetic and what is protective, and help you plan the right scope before any commitments.
