Serving Dumont, NJ (07628) from our Westwood shop since 1966

Your Dumont Plumber Since 1966

When your plumbing or HVAC fails in Dumont, you need a contractor who understands what they're walking into. Roughly a third of Dumont's housing stock predates 1940 — colonial revivals, pre-war Tudors, and early bungalows along Madison Avenue, Washington Avenue, and Knickerbocker Road that still carry original cast iron drain stacks and galvanized supply lines. H. Hofmeister has been working on Bergen County homes since 1966. We know the difference between a 1925 Dumont plumbing problem and a modern renovation, and we're family-owned, dual-licensed for both plumbing and HVAC, based right down Kinderkamack Road in Westwood.

What Dumont Homeowners Typically Call Us About

Dumont was incorporated in 1894 and built out in waves — heavy pre-1940 development along Madison Avenue and Washington Avenue, post-WWII expansion through the 1950s and 60s, and steady remodeling activity since. The result is a borough where the right plumbing or HVAC approach depends entirely on the era of the home. Roughly 30% of Dumont's housing stock predates 1940 — one of the higher pre-war proportions in Bergen County — and that drives a lot of the work we do here.

In Dumont's pre-war homes, the most common calls involve original galvanized steel supply lines that have corroded internally and dropped water pressure by 40–60% over their 80+ year life, cast iron drain stacks with pinhole leaks at horizontal joints, and old steam or hot-water radiator boilers nearing end of life. When we open walls during a kitchen or bath renovation in a 1920s Dumont colonial, we typically find a layered patchwork — original galvanized, mid-century copper splices, modern PEX or PVC, and old shutoff valves frozen in place. Sorting and repiping these systems is steady work for us.

Basement water is a recurring concern in Dumont. Older homes here often have stone foundations, brick foundations, or early poured concrete with cold joints, all of which let groundwater through during sustained rain. The borough's relatively flat topography toward the Hackensack River corridor doesn't help drainage. A properly sized sump pump with battery backup is the most cost-effective defense, and we install and service them throughout the borough. Pairing the pump with a French drain or improved exterior grading is sometimes the right combo for chronically wet basements.

Dumont is a denser borough than its neighbours to the north, and the housing sits much closer together on smaller lots. That geometry works in a homeowner's favour on underground work — service lines and sewer laterals have a shorter run from the house to the street than in a spread-out town like Closter, so excavation is usually a smaller job here. It works against you on access: less side yard means tighter working room around a bulkhead or a basement window when equipment has to come in or out.

The fixture count runs the other way too. Dumont houses generally carry fewer bathrooms than the larger homes north of the border, so the hot water complaints we get here are usually about a tank that has aged out rather than one that was undersized to begin with. Sediment, a spent anode rod and corrosion at the base are what end most Dumont water heaters, and that is a replacement conversation rather than a capacity one.

For renovation work, we handle plumbing rough-in, fixture installation, and HVAC integration. Dumont homes built before 1970 typically have boiler-and-radiator heat and no ductwork — meaning central AC retrofits require either a ductless mini-split solution or significant carpentry to thread ducts through century-old wall cavities. We walk through the tradeoffs honestly so you know what you're signing up for before the demo starts.

Why Dumont Homeowners Call H. Hofmeister

Dumont's homes deserve a contractor who knows the difference between working in a historic home and handling modern renovations. Here's why homeowners in the borough call us.

In Business Since 1966

We've been serving Bergen County for nearly 60 years. We've watched Dumont's housing stock age and know what to expect at each stage of a home's life cycle.

Comfortable with Every Era of Home

From Victorian and colonial homes with original cast iron and galvanized plumbing to modern renovations with contemporary systems, we work across the full range of housing types found in Dumont.

A Quick Drive Up Kinderkamack

Our Westwood shop is about 7 miles north — a 15-minute drive via Kinderkamack Road or New Bridge Road. Close enough for same-day service, local enough to know the streets and the housing stock.

Dual Licensed: Plumbing + HVAC

NJ plumbing license #10625 and HVAC license #19HC002574. One contractor for your pipes, your heating system, and your air conditioning. Fewer vendors, less coordination.

Family Business, Not a Franchise

We're a local family company. When you call (201) 666-1118, you reach people who live and work in Bergen County, not a national call center dispatching from out of the area.

Services for Dumont Homes

Whether you're maintaining a historic home, renovating a mid-century house, or updating systems, we provide the full range of residential plumbing, heating, and cooling services.

Plumbing

Pipe Replacement & Repiping

Dumont's older homes often have corroded galvanized supply lines or aging cast iron drains. We replace deteriorated piping with copper or PEX for supply and PVC for drains, restoring water pressure and flow.

Renovation Plumbing

Kitchen and bathroom renovations in older Dumont homes often uncover patchwork plumbing from decades of repairs. We sort out mixed-material systems and bring plumbing up to current code as part of the renovation.

Water Heater Replacement

Larger Dumont homes with multiple bathrooms can outgrow a standard 40- or 50-gallon tank. We install right-sized tank replacements and tankless systems for homes with higher hot water demand.

Sump Pump Installation & Service

Older foundations in Dumont are prone to groundwater intrusion. We install primary sump pumps and battery-backup systems to keep basements dry during heavy rain and power outages.

Drain Cleaning & Sewer Service

Tree root intrusion, grease buildup, and deterioration in older clay or cast iron sewer laterals cause slow drains and backups. We clear lines and inspect with cameras to find the source.

Fixture Installation

From faucets and sinks to toilets and showers, we install quality fixtures and ensure proper connections and sealing.

Heating

Boiler Repair & Replacement

Hot water baseboard heating is standard in many of Dumont's older homes. We service boilers of all makes and install high-efficiency replacements when repair is no longer cost-effective.

Furnace Service

Newer Dumont homes and major renovations often use forced-air furnaces. We repair, maintain, and replace gas and electric furnaces.

Seasonal Heating Maintenance

Annual boiler or furnace maintenance in early fall catches worn components before the heating season. We recommend scheduling in September or October for the best availability.

Air Conditioning

Ductless Mini Split Installation

Many of Dumont's older homes heat with boilers and have no ductwork. Ductless mini splits add efficient zone cooling without the disruption of installing ducts through finished walls and ceilings.

Central AC Repair & Installation

For homes with existing ductwork or renovations, we repair and install central air conditioning systems. We size units based on the home's square footage, insulation, and layout.

AC Maintenance

Spring tune-ups clean coils, check refrigerant, and test controls so your system runs efficiently through Bergen County's humid summer months.

Common Issues We Help With in Dumont

Dumont's mix of historic, mid-century, and renovated homes creates a wide range of plumbing and HVAC challenges.

Patchwork Plumbing in Renovated Older Homes

Pre-war and early post-war homes in Dumont have often been renovated multiple times over the decades. Each renovation may have introduced different pipe materials and methods, leaving behind a patchwork system. Copper connected to galvanized with dissimilar-metal fittings, cast iron transitioning to PVC mid-run, and supply lines that take indirect paths through finished spaces are all common. Untangling these systems and replacing the weakest sections is a regular part of our work.

Basement Moisture in Older Foundations

Dumont's older homes - particularly those with stone or block foundations - can allow groundwater intrusion after sustained or heavy rain. A properly sized sump pump with battery backup is the standard solution, and we install and maintain these systems throughout the borough.

Updating Systems in Renovated Homes

Dumont has an active renovation market, with homeowners updating kitchens, bathrooms, and HVAC systems in mid-century and older homes. We work with homeowners and contractors to ensure plumbing and HVAC systems are properly sized and installed to code.

Adding Cooling to Boiler-Heated Homes

Many of Dumont's pre-war and mid-century homes heat with boilers and hot water baseboard, which means there's no ductwork for air conditioning. Ductless mini split systems solve this by providing efficient zone cooling through compact wall-mounted units.

Dumont Service FAQs

(201) 666-1118

How far is H. Hofmeister from Dumont?

We are located at 115 Bergenline Ave in Westwood, about 3 miles from Dumont. The drive takes roughly 5 minutes via Emerson, which sits between us. We've been serving Dumont homeowners since we opened in 1966.

I'm renovating an older Dumont home. Can you handle the plumbing?

Yes. We regularly work on renovations in Dumont's older homes, including pre-war colonials and mid-century houses being updated. We can replace galvanized supply lines, swap cast iron drain stacks for modern PVC, install new fixtures, and rough in plumbing for reconfigured kitchens and bathrooms. We work carefully in older structures where walls and floors may conceal outdated or non-standard piping.

My basement gets damp after heavy rain. What can be done?

Basement moisture is common in Dumont, especially in homes with older stone or block foundations. A properly installed sump pump with a battery backup can manage water that enters below grade. We can assess your basement, recommend a pump system, and install it. For homes that already have a sump pump but still have moisture issues, the pump may be undersized, failing, or the drainage leading to it may need attention.

Do you do plumbing for new construction homes?

Yes. Dumont has seen a number of renovation and new construction projects in recent years. We handle plumbing rough-ins and finish work for new residential construction, including multi-bathroom layouts, tankless water heaters, and gas line installation.

My home has a boiler but I want to add central air. Is that possible?

Yes, and it's a common request in Dumont. Many mid-century and pre-war homes heat with hot water boilers and baseboard radiators, which means there's no existing ductwork for cooling. We install ductless mini split systems that provide zone cooling without requiring ductwork. For renovations where ductwork is being added, we can install a traditional central AC system as well.

What are your license numbers?

Our NJ plumbing license is #10625 and our HVAC license is #19HC002574. We are fully licensed, bonded, and insured for all plumbing, heating, and air conditioning work in Dumont and Bergen County.

Quick facts

Quick answer: In Dumont, NJ 07628 the housing sits on close-set lots with short service runs but tight equipment access, so the constraint on a water heater or boiler swap is usually getting the unit in and the old one out rather than the run length. H. Hofmeister & Co. has handled that from Westwood since 1966. Veolia municipal water. Call (201) 666-1118.
