Magnolia is a one-stop general contractor in Warren County, NJ. Whether your project starts with a leaking roof and ends with a finished basement, or begins as a kitchen update that expands into a full home renovation, we handle it all in-house. Our services cover every corner of your home.

On the exterior, we install and replace roofing in shingle, flat, and metal options. We offer full siding installation, including vinyl and fiber cement options. We install replacement windows, build and replace decks in wood and composite materials, and handle all types of masonry and paving, including brick and stone fronts, paver patios and walkways, masonry steps, and cement driveways. We also build and repair porches and steps, and install patios and walkways from the ground up.

Inside, we remodel kitchens, bathrooms, and basements, handle interior trim and finish work, and plan and build home additions and dormers.

What sets Magnolia apart is a commitment to doing things right the first time. Every project is completed using high-quality, reliable materials, and every finish is held to a standard most contractors don't bother with. From the first estimate to the final walkthrough, each job is managed with dedicated supervision, transparent communication, and the same level of care and accountability.

Much of Warren County's housing stock dates to the mid-20th century. Homes built between the 1950s and 1980s in towns like Phillipsburg, Washington, Hackettstown, and Blairstown are now anywhere from 40 to over 70 years old, and they tend to share a common set of needs.

A roof from that era has almost certainly exceeded its service life. Aging shingles and deteriorating flashing create leak pathways that, if left unaddressed, cause far more extensive damage to insulation, framing, and interior finishes. Replacing a roof before it fails is always less costly than repairing the damage that follows.

Older siding, whether it's original wood clapboard, aluminum, or early vinyl, tends to lose its protective function over time. When it cracks, warps, or allows moisture behind the wall, energy efficiency drops and structural issues can follow. Modern fiber cement and premium vinyl siding offer significantly better performance and durability for Warren County's winters.

Original windows in homes of that age are typically single-pane and poorly sealed, contributing to drafts and elevated heating costs. Energy Star-rated replacement windows address both issues and tend to pay back in reduced utility bills over time.

Inside, kitchens and bathrooms that have never been updated often carry layouts and materials that no longer serve a household well. A full remodel in either space improves daily function, brings the home up to current code where applicable, and adds measurable value to the property.

For homeowners who have lived in their Warren County home for decades and want to stay, rather than move, an addition or dormer is often the most practical way to gain the space a growing or changing household needs.

Warren County's geography creates specific conditions for homes. The county sits along the Delaware River valley, with areas of elevated terrain near the Kittatinny Ridge and Jenny Jump State Forest. That translates to colder winters, more pronounced freeze-thaw cycles, and exposure to wind and moisture that accelerates wear on a home's exterior surfaces.

Freeze-thaw activity is especially hard on masonry. Mortar joints in brick or stone work, chimney crowns, and paver installations all expand and contract with temperature swings. Cracks form, water infiltrates, and the problem compounds season after season if not addressed. Tuckpointing, masonry repairs, and proper patio and walkway installation help protect against this cycle.

The same logic applies to roofing and siding. An undetected roof penetration or a section of damaged siding does not stay a small problem through a New Jersey winter. Addressing wear early, before it becomes damaged, is what keeps a home structurally sound and protects its value.

According to the U.S. Census Bureau, the median property value in Warren County reached $346,500 in 2024, up 7.24% from the prior year. With homeownership rates at 75.1%, well above the national average, most residents here have a significant financial interest in the condition of their home. Regular updates and proactive maintenance are how that investment is protected.

A general contractor is well-positioned to support this kind of ongoing care. Rather than coordinating separate roofing, siding, and masonry contractors for a project that spans all three areas, a single contractor manages the scope, schedule, and quality of every trade involved.

Magnolia has been in business since 1996. In that time, we've worked on thousands of homes across New Jersey, and we've built a reputation that's reflected in our A+ BBB rating, our licensed and insured status, and the referrals we receive from homeowners who've worked with us before.

We're family-owned, and that shows in how we approach every project. Owners Vic and Chris are involved in the work, not just the business. Every project has a dedicated supervisor. We communicate throughout the process — before, during, and after — so you're never left wondering about the status of your home.

We work with premium materials from GAF, James Hardie, Trex, CertainTeed, and other leading brands, and we handle permitting, coordination, and project management as part of our full-service offering. You don't need to manage the process. That's what we're here for.
