If you have ever asked yourself what actually happens during a home inspection, you are not alone. It is one of the most common questions I get from buyers, sellers, and real estate agents throughout Central New Jersey. Whether you are purchasing your first home in Edison, selling a property in East Brunswick, or refinancing in Old Bridge, understanding what a home inspection covers gives you a real advantage going into the transaction.
A thorough home inspection is not just a walk-through with a flashlight. It is a systematic, licensed evaluation of the condition of a property from the roof down to the foundation. At DGM Inspection, we follow the standards of practice required by the State of New Jersey and work room by room, system by system, to give our clients the most complete picture possible of the home they are buying or selling.
In this guide, I am going to walk you through exactly what a home inspection includes in New Jersey, broken down by area of the home. By the end, you will know what to expect, what to watch out for, and how to use the inspection to your benefit.
Why a Home Inspection Matters in New Jersey
New Jersey homes face a specific set of challenges that inspectors in other states rarely encounter. We get brutally cold winters with repeated freeze-thaw cycles that stress foundations and drainage systems. We get humid summers that drive moisture into basements and crawl spaces. We have older housing stock, particularly in towns like Metuchen, Bound Brook, Highland Park, and New Brunswick, where homes built decades ago are now going through major transactions.
A home inspection performed by a licensed New Jersey inspector gives you documentation of the current condition of the property. That means fewer surprises after closing, stronger negotiating power during the transaction, and peace of mind for everyone involved. For sellers in South Brunswick or Sayreville, a pre-listing inspection can speed up the sale and prevent deals from falling apart during due diligence.
Exterior Inspection: What We Look at First
Every home inspection at DGM Inspection begins outside. The exterior of a home reveals a great deal about how it has been maintained and how well it will hold up over time. Here in Middlesex County, where we see everything from colonial-era construction to modern developments, the exterior tells a story before we ever open the front door.
Roof
The roof is one of the most critical and most expensive components of any home. During the inspection, I examine the roofing material for age, wear, missing or damaged shingles, and signs of improper repairs. I also look at the flashing around chimneys, vents, and skylights, which is a common area for water intrusion, especially after New Jersey winters.
What We Check on the Roof:
- Shingle condition, curling, cracking, and missing sections
- Flashing integrity at chimneys, dormers, and roof valleys
- Ridge and soffit ventilation
- Gutters, downspouts, and drainage direction
- Visible signs of prior repairs or patching
- Fascia and soffit board condition
Foundation and Grading
Foundation problems are a serious concern in New Jersey, particularly because of our clay-heavy soils and freeze-thaw weather patterns. I inspect the visible portions of the foundation for cracks, settlement, bowing, and moisture staining. I also check the grading around the home to confirm that water is directed away from the structure rather than pooling against the foundation walls.
Siding, Windows, and Doors
The home’s exterior cladding, whether it is vinyl, brick, stucco, or wood, is inspected for damage, gaps, and signs of water infiltration. Windows are checked for failed seals, damaged frames, and proper weatherstripping. Exterior doors are examined for fit, locking hardware, and threshold seals. These details matter a lot in homes throughout Monroe Township and Woodbridge, where mixed construction styles are common.
Driveway, Walkways, and Decks
Cracked driveways and uneven walkways are safety hazards and can signal soil movement beneath the surface. Decks and porches get a close look for structural connections, ledger board attachment, post footings, decking condition, and railing stability. An improperly attached deck is one of the more dangerous defects I come across, and it is more common than most buyers expect.
Interior Inspection: Going Room by Room
Once we move inside, the inspection becomes a systematic review of every accessible room and space in the home. Here is what that process looks like in practice.
Attic
Many buyers overlook the attic, but it is one of the most revealing spaces in any home. I access the attic to evaluate insulation levels, ventilation, signs of moisture or mold, and the structure of the roof framing from the inside. In older Central Jersey homes, I frequently find inadequate insulation, blocked soffit vents, or evidence of prior roof leaks that were never properly addressed.
Attic Inspection Includes:
- Insulation type, depth, and coverage
- Ventilation balance between intake and exhaust
- Roof sheathing condition and visible structural members
- Signs of moisture, staining, or mold growth
- Bathroom exhaust fans that vent directly into the attic (a common and problematic find)
Kitchen
The kitchen is one of the highest-traffic areas of any home and has a lot of systems packed into a small space. During the kitchen inspection, I run the dishwasher, test the garbage disposal, check under-sink plumbing for leaks, and verify that the range hood is actually vented to the exterior. I also test all accessible outlets and look for GFCI protection near the sink.
Kitchen Checklist:
- Sink and faucet operation, water pressure, and drainage
- Under-sink cabinet for leaks and moisture damage
- Dishwasher operation and proper drainage
- Refrigerator water supply line condition
- Range hood ventilation to the exterior
- GFCI outlet protection within 6 feet of the sink
- Cabinet door alignment and condition
Bathrooms
Bathrooms are where water damage hides most effectively. I test every fixture, check the toilet for stability and proper sealing, and press against the tile and flooring around the tub and shower to feel for soft spots or water damage underneath. Exhaust fans are tested for proper operation and, importantly, checked to confirm they vent outside rather than into a wall cavity or the attic.
Bathroom Inspection Items:
- Toilet stability, flushing, and wax seal condition
- Tub and shower caulking and grout integrity
- Tile and flooring for soft spots or delamination
- Vanity plumbing under the sink
- Exhaust fan operation and proper venting
- GFCI protection at all outlets
- Water pressure and drainage speed at each fixture
Bedrooms and Living Areas
Every bedroom and main living area is inspected for ceiling and wall conditions, window operation and locking, electrical outlets, and visible structural concerns. I look for evidence of water intrusion from above or from the exterior, and I test smoke and carbon monoxide detectors where accessible. Closets are also opened and checked for moisture, mold, or structural concerns behind stored items.
Basement and Crawl Space
In New Jersey, the basement is often the first place to tell you about bigger problems elsewhere in the home. I inspect the basement for water staining, efflorescence on block walls, sump pump operation, and cracks in the foundation walls. The type and pattern of cracks matter significantly. A horizontal crack in a block wall is a very different situation from a vertical shrinkage crack in poured concrete, and I will always explain what I am seeing in plain terms.
Crawl spaces are inspected for vapor barriers, insulation condition, signs of moisture and wood rot, pest damage, and the condition of structural components overhead. Many crawl spaces in Piscataway and Old Bridge are under-ventilated, which contributes to moisture buildup and wood deterioration over time.
Major Systems: Electrical, Plumbing, and HVAC
Beyond the structure and finishes of the home, a licensed home inspection in New Jersey covers the major mechanical systems that keep the home running safely and comfortably. These systems are often the most costly to repair or replace, so this part of the inspection deserves very close attention.
Electrical System
I inspect the main electrical panel for proper breaker sizing, double-tapping, signs of overheating, and the panel brand. Certain panel brands that were common in older New Jersey homes have known safety issues and should be evaluated carefully. I also test a representative sample of outlets throughout the home, check for AFCI and GFCI protection where required, and look for exposed or improper wiring.
Electrical Inspection Covers:
- Main service panel and breaker condition
- Grounding and bonding
- GFCI protection in kitchens, bathrooms, garages, and exterior areas
- Aluminum wiring identification (common in 1960s and 1970s homes)
- Accessible wiring in the basement, attic, and utility areas
- Smoke and CO detector presence and functionality
Plumbing System
Plumbing is inspected from the water main entry to every fixture in the home. I check water pressure, test all faucets and toilets, inspect visible supply and drain lines for material and leaks, and evaluate the water heater for age, proper installation, and safety features. In older homes throughout Central Jersey, I often find a mix of older galvanized steel lines alongside newer copper or PEX, which can signal prior repairs or partial updates worth understanding.
Plumbing Inspection Includes:
- Water supply pressure and flow
- Visible supply and drain pipe material and condition
- Water heater age, capacity, and temperature-pressure relief valve
- Sump pump operation and discharge location
- Hose bibs and exterior shutoffs
- Signs of prior leaks or moisture damage behind visible surfaces
Heating and Cooling Systems (HVAC)
The HVAC system is one of the largest investments a homeowner makes. I operate both heating and cooling at the time of inspection and document the age of the equipment, visible condition, filter status, and any operational concerns. New Jersey summers are hot and humid, and New Jersey winters are hard on heating systems. Knowing the age and condition of the HVAC before closing can save buyers thousands of dollars.
HVAC Inspection Covers:
- Furnace or boiler operation, age, and heat exchanger condition
- Central air conditioning cooling performance
- Ductwork for visible leaks, damage, or disconnected sections
- Thermostat operation and response
- Air filter condition
- Fuel supply lines and connections
- Flue and exhaust venting for all heating equipment
Garage and Outbuildings
Garages are inspected as part of the standard NJ home inspection. The automatic garage door opener is tested for proper function and, importantly, for the reverse safety mechanism that should stop and reverse the door when it contacts an obstruction. The garage floor is checked for cracks, drainage, and oil staining. The door between the garage and living space is checked for fire-rated construction and proper self-closing hardware, which is a critical safety requirement that is frequently missing.
Detached garages, sheds, and other outbuildings on the property are also inspected for structural condition, roofing, and any electrical connections. These spaces are sometimes overlooked but can represent real repair costs and safety concerns.

How Home Buyers Can Use the Inspection
For buyers, the home inspection report is one of the most valuable documents in the entire real estate transaction. Here is how to make the most of it.
- Attend the inspection in person. Walking through the home with the inspector gives you context that a written report alone cannot fully convey.
- Use the report to prioritize. Not every finding is equally significant. Safety issues and major system deficiencies carry far more weight than cosmetic concerns.
- Negotiate strategically. In competitive markets across Middlesex County, a detailed inspection report lets you ask for credits or repairs on the items that matter most.
- Plan your budget. Even when defects are minor, the report helps you estimate near-term maintenance and repair costs after closing.
- Ask questions. At DGM Inspection, Gregory is happy to explain every finding in plain language before you leave the property.
How Home Sellers Benefit from a Pre-Listing Inspection
Pre-listing inspections are one of the smartest moves a seller in Central New Jersey can make. Here is why.
- Know your home’s condition before buyers do. Surprises discovered by a buyer’s inspector can derail a deal days before closing. Your own inspection removes that uncertainty.
- Set the right asking price. If you know the roof needs attention or the HVAC is aging, you can price accordingly or make the repair upfront.
- Speed up the transaction. Buyers often feel more confident when the seller can provide a recent inspection report, which reduces the back-and-forth after their own inspection.
- Demonstrate transparency. In tight markets in Edison, South Brunswick, and Monroe Township, sellers who disclose proactively tend to attract more serious offers.
What a Standard Home Inspection Does Not Cover
A home inspection in New Jersey is a visual, non-invasive evaluation. There are a number of things that fall outside the scope of the standard inspection, and it is important for buyers and sellers to understand this before scheduling.
- Radon testing: Radon is a significant concern in NJ and requires a separate test. DGM Inspection offers radon testing as a convenient add-on service.
- Mold testing: While visible mold growth is noted during the inspection, air quality testing for mold requires a separate laboratory analysis.
- Sewer scope inspection: The condition of underground sewer lines is not included in a standard inspection. A sewer scope is strongly recommended for older properties.
- Pest inspection: Wood-destroying insect inspections (WDI) are a separate service, though they are often conducted at the same time as the home inspection.
- Well and septic systems: Properties in rural parts of Middlesex County or beyond may have private well and septic systems that require their own specialized evaluation.
- Asbestos and lead paint testing: These require laboratory sampling and are outside the scope of a visual inspection.
DGM Inspection can coordinate or recommend qualified professionals for these additional services, so you walk away with a complete picture of the property.
Commercial Property Inspections in Central New Jersey
Beyond residential homes, DGM Inspection also provides commercial property inspections for businesses, investors, and property managers throughout Middlesex County. Commercial inspections follow a similar systematic approach but are scaled to the complexity of the building, including multi-unit properties, mixed-use spaces, and light commercial structures.
Whether you are acquiring a small retail space in New Brunswick or evaluating a multi-family building in Woodbridge, a licensed commercial inspection gives you the documentation you need to make a sound investment decision.

Frequently Asked Questions About Home Inspections in New Jersey
How long does a home inspection take in New Jersey?
Most standard home inspections in Central New Jersey take between two and four hours, depending on the size, age, and condition of the home. Larger properties or those with more complex systems may take longer. I always recommend that buyers attend the inspection in person, since being there adds a lot of value beyond what the written report alone can provide.
How much does a home inspection cost in New Jersey?
Home inspection costs in NJ typically range from $350 to $600 or more, depending on the size of the property and any add-on services such as radon testing. At DGM Inspection, our pricing is competitive for the Central New Jersey market. Visit dgminspection.com or contact us directly for a quote specific to your property.
Do I have to be present during a home inspection in NJ?
You are not required to be present, but I strongly encourage buyers to attend. Walking through the home with an experienced inspector gives you context that a written report cannot fully replace. You can ask questions in real time and leave with a much clearer picture of what the findings mean for your decision.
What is not included in a standard New Jersey home inspection?
A standard home inspection does not include radon testing, mold air sampling, sewer scope, pest or termite inspection, well and septic evaluation, or testing for lead paint and asbestos. These require separate services. DGM Inspection can help coordinate or recommend qualified professionals for these evaluations based on your property.
Can a seller request a home inspection in New Jersey?
Absolutely. Pre-listing inspections are increasingly popular in Central NJ because they give sellers advance knowledge of any issues that could complicate the sale. A pre-listing inspection through DGM Inspection helps you price your home accurately, make strategic repairs, and reduce the risk of a deal falling apart after the buyer’s inspection.
What do home inspectors look for in the basement in NJ?
In the basement, a licensed NJ inspector checks the foundation walls for cracking, bowing, and signs of water infiltration. They test the sump pump, look for efflorescence and moisture staining, examine structural posts and beams, and note any plumbing, electrical, or HVAC components in the space. Basement conditions are especially important in New Jersey given our climate and soil conditions.
Is radon testing included in a NJ home inspection?
Radon testing is not part of the standard home inspection scope, but it is highly recommended for properties in New Jersey, which has elevated radon levels in many counties. DGM Inspection offers radon testing as a separate add-on service that can be conducted simultaneously with the home inspection for your convenience.
How do I find a licensed home inspector in New Jersey?
Home inspectors in New Jersey are required to hold a state license issued by the NJ Department of Community Affairs. You can verify a license on the DCA website. Gregory Anzano of DGM Inspection holds NJ State License #24GI00201100 and serves Central New Jersey, including Edison, East Brunswick, Piscataway, Woodbridge, Metuchen, Old Bridge, South Brunswick, Sayreville, Monroe Township, Bound Brook, Highland Park, and Milltown.
