Properties in and around Oldwick sit on generous multi-acre lots carved out of Hunterdon County’s rolling hills, where wooded terrain, natural grade changes, and full seasonal weather cycles demand outdoor construction that is built to last and designed to belong. The freeze-thaw patterns that define New Jersey winters stress framing and fasteners in ways that only quality materials and proper construction methods can withstand. Decks by Kiefer is a deck builder in Oldwick, NJ that understands those demands and builds to meet them.
Bob Kiefer founded Decks by Kiefer in 1986 with a background in landscape architecture and a standard of craftsmanship that has earned multiple NADRA awards and national recognition in publications, including Professional Deck Builder and Popular Mechanics. Homeowners in communities like Oldwick, Tewksbury, and Pottersville trust Decks by Kiefer because every project receives one dedicated crew, Bob’s personal oversight from design through the final walkthrough, and materials sourced at a level no competitor can match.
One Crew, One Standard, No Competing Jobs Pulling Focus From Yours

Most deck builders in New Jersey run several projects at once, dividing crews and attention among multiple job sites. We work on one project at a time, giving each build a dedicated crew and focused oversight from the first design conversation through the final walkthrough.
Our approach has produced more than 1,000 completed decks. We have a process built around quality control and direct supervision that leads to cleaner builds, tighter timelines, and fewer surprises during construction.
Material sourcing is another advantage. As a direct importer of Ipe hardwood, Decks By Kiefer assures quality from origin to installation, giving homeowners access to one of the most durable decking materials available for environments where seasonal weather extremes, moisture, and UV exposure take a toll year after year.
Ipe’s natural density makes it highly resistant to rot, insects, and weathering without chemical treatment. With a lifespan often reaching 40 to 75 years, it remains one of the most reliable materials for long-term construction in New Jersey’s variable climate. It is why we recommend it.
Your Complete Outdoor Living and Deck Builder in Oldwick, NJ
Decks by Kiefer builds the full range of outdoor living projects, from single-level custom decks to complete outdoor environments with pergolas, fire features, and screened enclosures. Every service below is designed with the same precision and built to the same structural standard.
Custom Decks
A custom deck starts with a site visit, not a catalog. The design is built around your property’s grade, your home’s architecture, and how your family actually uses outdoor space, so the finished deck looks like it belongs rather than like something bolted to the back of the house. The sloped, wooded lots common throughout the Oldwick area are well-suited to multi-level decks that step down across the terrain, giving each area a defined purpose, whether that is dining, lounging, or entertaining while surrounded by mature tree canopy.
Pool and swim spa decks are designed with drainage, slip resistance, and constant moisture exposure factored in from the start. Single-level builds on flatter portions of a property, and our deck contractor in Oldwick, NJ, are designed with the same precision and material standards as any other project, because the simplicity of the layout is no reason to compromise on the quality of the result.
Curved Decks
Most decking contractors avoid curved decks because the geometry is unforgiving and the skill required goes well beyond standard construction. A curved deck has to account for the arc at every stage, from how the frame is laid out to how each board is cut, how the stairs flow from the surface, and how the railing follows the edge without creating flat segments that break the visual line. The result, when done correctly, is an outdoor space that looks as if it grew out of the landscape rather than was placed on top of it. For this reason, Bob Kiefer earned a reputation as the King of Curved Decks.
Deck Features
The details built into a deck are what separate a finished outdoor space from a finished construction project. Deck railings installation here means cable systems from Feeney and Cable Bullet that preserve your sightlines across a wooded yard or open property while standing up to the moisture and UV exposure that deteriorate painted wood alternatives over time.
Dryspace underdeck ceiling systems capture surface water and redirect it through a drainage channel, converting the space below an elevated deck into a dry, usable outdoor room. Built-in bench seating, custom planters, stair lighting, and recessed deck lighting are all planned from the layout stage, so every element looks intentional rather than added on after the fact.
Deck Materials
The material you choose determines how your deck looks on day one and how it performs 20 years from now. Ipe is a Brazilian hardwood that is naturally resistant to rot, insects, fire, and weathering without any chemical treatment, and its density gives it a lifespan of 40 to 75 years that no composite product can match.
Kiefer Oil is a proprietary stain developed specifically for fine wood surfaces like Ipe, penetrating the grain to protect against UV exposure and moisture far more effectively than anything available off the shelf. TimberTech and AZEK composites are also available for homeowners who want a clean, consistent surface with minimal upkeep.
Outdoor Living Structures
A well-designed outdoor space extends beyond the deck surface into the structures that define how you use it across New Jersey’s four seasons. As a porch contractor and gazebo builder, the company builds covered porches, screened porches, screen rooms, pavilions, and gazebos as permanent architectural additions that look like they were always part of the home. Louvered pergola systems with motorized slats let you adjust for sun, shade, or rain without leaving your seat.
As a patio builder serving Oldwick and the surrounding communities, the company designs custom paver patios, outdoor kitchens with built-in grills and refrigeration, and fire pits and fireplaces as integrated components of the overall outdoor environment.
