Every home inspection turns up something. Even on a well-kept Bucks County twin or a recently renovated Montgomery County colonial, the report usually lists at least a dozen items that need attention. Most of those entries are routine maintenance. A handful, though, repeat across nearly every property we walk through. Knowing which findings are normal and which deserve a closer look helps you read the report without panicking and focus your negotiating leverage where it actually matters.
After more than 30 years and 15,000+ inspections across Bucks County, Montgomery County, and Philadelphia, the same problem categories show up again and again. This article walks through the findings we see most often, which ones tend to be deal-breakers, how to react when something serious is flagged, and what sellers can do before the inspector ever rings the doorbell.
What Kinds Of Issues Show Up Most On Inspection Reports?
Plumbing, roofing, electrical, HVAC, water management, and pest exposure are the categories that dominate most residential reports. Within those categories, a short list of findings repeat from house to house.
Roof and gutter problems. Aging shingles, lifted flashing around chimneys and vents, missing kickout flashing where a roof meets vertical siding, and clogged or detached gutters all rank near the top of the list. Even on newer construction, a single poorly sealed pipe boot can stain a ceiling within a year. We see roof callouts on roughly three out of four homes we inspect in the Delaware Valley, and on most of those the fix is a few hundred dollars, not a re-roof.
Water management around the foundation. Negative grading where the soil slopes toward the house, downspouts that dump within a foot of the foundation wall, missing splash blocks, and damp crawl spaces show up across most older Philadelphia rowhomes and twin homes throughout Montgomery County. These items are usually inexpensive to fix and very expensive to ignore. A wet basement that started as a clogged downspout becomes a mold and foundation conversation if it runs for a few seasons.
Electrical safety items. Open junction boxes, double-tapped breakers, missing GFCI protection in bathrooms, kitchens, and exterior receptacles, and panels with mismatched breaker brands are all common. Many of these were code-compliant when the house was originally wired but now read as safety items on a modern report. Most are an electrician half-day repair, not a panel replacement.
HVAC age and service history. Furnaces and air conditioners past 15 to 20 years almost always pick up a note. The system might still run, but the report flags it as nearing end of life so the buyer can plan a budget. Cracked heat exchangers, refrigerant leaks, and condensate drain lines plumbed into the wrong place are the specific concerns that escalate the note from informational to actionable.
Which Systems Get Flagged Most On Older Homes?
Older Delaware Valley housing stock has its own predictable list: knob-and-tube wiring tucked into walls and attics, undersized 60-amp electrical service, original cast iron drain stacks that have begun to crack at the hub, single-pane windows past their sealing life, and outdated polybutylene or galvanized plumbing supply lines.
These items rarely demand an emergency repair, but they reshape the negotiation and the first-year-of-ownership budget. A buyer who walks in knowing the wiring is partially knob-and-tube can plan a phased rewire and price it into the offer instead of being blindsided by an insurance carrier the week after closing.
Which Findings Tend To Be Deal-Breakers?
Most inspection findings are negotiable. A handful are not. The line usually runs along three words: structural, safety, and active.
Structural concerns. Visible foundation cracks wider than a quarter inch, sloping or sagging floors that suggest compromised joists, and shifting brick walls all warrant a follow-up by a licensed structural engineer. These are not findings inspectors guess at. The report identifies the pattern and recommends a specialist for the load-bearing call, and that specialist evaluation should happen before the contingency window closes.
Active water intrusion. Wet basement walls, standing water around a sump pit, or visible staining on a recently painted ceiling tell a very different story than a long-dry watermark. Active intrusion often costs thousands to chase down properly because the source might be a roof leak two rooms away, a failed window flashing, or a buried supply line under the slab.
Major system failures. A furnace that no longer fires, a water heater past its service life leaking from the base, an electrical panel with corroded or burned bus bars, or a main sewer line with a visible bellow or root intrusion all qualify. These are not optional repairs. They get addressed before move-in either by the seller or through a credit large enough for the buyer to handle it immediately.
Stucco moisture damage. Synthetic stucco systems installed across the Delaware Valley in the 1990s and early 2000s have a long history of trapping moisture behind the cladding. A thermal scan and probe test often reveals damage that looks completely fine from the curb. Severe cases require a full system replacement, which is why buyers in stucco-clad neighborhoods often request a specialized stucco moisture evaluation before closing rather than waiting on the standard visual inspection.
Radon at action levels. The EPA action level is 4 pCi/L. A test that returns higher than that warrants mitigation before move-in. Mitigation is a known, fixable process and usually a few thousand dollars, but it is a real line item buyers should address while they still have negotiating leverage in the contract.
How Should Buyers React When Issues Are Flagged?
Most buyers panic at first. The instinct is to count findings. A long report feels worse than a short one, even when the long report is mostly minor maintenance items and the short report contains the one big-ticket problem.
A better approach is to sort findings into three buckets before opening any negotiation.
Safety and structural items go first. These are non-negotiable. They get a written request for repair, a credit at closing, or a renegotiated price. This bucket includes anything tagged as a safety issue on the report, structural callouts, active water intrusion, and code-required items like missing smoke or carbon monoxide detectors.
Major system items go second. A water heater near end of life, a roof past 20 years, an HVAC system that no longer cools to spec, a main electrical panel that is undersized for the way the home is actually used. These items get priced. You ask for a credit reflecting what you will spend in the first year or two of ownership, not the full replacement cost on day one.
Maintenance items go third. Caulking, paint, dryer vent cleaning, missing weather seals, a loose handrail. You note them, plan to address them yourself after closing, and do not burn leverage asking the seller to fix them. Building a clean, focused list is exactly the situation where knowing what to ask for after a home inspection makes the difference between losing a good house over $400 in caulking and walking away from a hidden $30,000 problem.
When Should You Bring In A Specialist?
Home inspectors are generalists. When the report flags a major roof concern, a structural anomaly, a complex electrical issue, significant stucco moisture readings, or an elevated radon result, the next step is a licensed specialist who can give a scope and cost for the repair. Treat the inspector’s recommendation to consult a specialist as a real instruction, not a hedge.
A specialist evaluation costs a few hundred dollars and almost always pays for itself in negotiation accuracy. Walking into a counter-offer with a contractor’s written estimate is much stronger than walking in with “the report said it might be expensive.” It also protects the buyer if the seller pushes back and the deal ends up needing a contingency extension.
What Can Sellers Do Before The Inspector Arrives?
Sellers are not powerless. A weekend of preparation often removes the easiest findings from the report before the inspector ever opens the front door, and a cleaner report holds up better through buyer negotiation.
Replace missing or burned-out lightbulbs. Inspectors mark every non-working bulb. A page of “fixture inoperative” entries reads worse than it deserves and gives buyers the impression that something larger is being hidden.
Clear access to mechanicals. A blocked electrical panel, an attic hatch behind a stack of boxes, or a furnace pinned in by basement clutter all become noted limitations in the report. The inspector cannot fully evaluate what they cannot see, and that uncertainty makes buyers nervous in a way that usually shows up at the negotiation table.
Test smoke and carbon monoxide detectors. Pennsylvania requires functional detectors near every sleeping area. A missing or dead detector is a code item that ends up in the request-for-repair list, and it is one of the cheapest items to address before listing.
Fix the obvious water management problems. Clean the gutters, extend downspouts past the foundation, regrade obvious low spots near the house, reseal an aging garage threshold, and address any visible chimney cap or flashing problem before the inspector photographs it. These are weekend repairs that prevent five-figure conversations later.
Service the HVAC. Replace the filter, vacuum around the unit, and run both heat and air conditioning the day before the inspection. A clean, working system that performs to spec reads differently in a report than a dusty one with a clogged filter that struggles to hold temperature.
Do not hide known defects. Pennsylvania’s Real Estate Seller Disclosure Law requires sellers to disclose known material defects in writing. Patching over a stain or repainting around active moisture creates legal exposure later and almost always backfires when the inspector pulls the panel anyway. The right move is to fix the issue cleanly or disclose it clearly and price it into the listing.
A pre-listing inspection often pays for itself by surfacing these items in advance. Sellers who go that route already know which findings to address before going on market and which to price into the listing, which removes most of the post-offer surprises that derail closings.
Frequently Asked Questions
How long does a typical home inspection take?
Most residential inspections in our service area take three to four hours for a standard single-family home. Larger properties, older homes, and homes with detached structures like a separate garage or finished basement take longer. The written report itself usually arrives within 24 to 48 hours of the visit, with photographs of every flagged item.
Do all houses fail home inspections?
Home inspections do not have a pass or fail grade. The report is a condition snapshot. Every house, including brand-new construction, will have items listed. The relevant question is which items matter for your decision and your budget, not whether the report has zero findings. A report with zero findings should actually raise eyebrows.
Are minor cosmetic issues worth negotiating?
Generally no. Cosmetic items, missing weather stripping, and small caulking jobs erode goodwill at the negotiation table without recovering meaningful dollars. Save your leverage for safety, structural, and major system items where the dollar amounts actually move the deal and where the seller can see a clear reason to come to the table.
Who pays for repairs after a home inspection?
That is negotiated between buyer and seller in the contract. Common outcomes include a seller credit at closing, a price reduction, the seller hiring a contractor before settlement, or the buyer accepting items as-is in exchange for a different concession. Pennsylvania contracts generally give buyers a defined inspection contingency window to make these requests.
Can a home inspection report be shared between buyers?
Reports are commissioned by and licensed to the buyer who paid for them. If a deal falls through and a new buyer asks about the prior report, sharing requires the original buyer’s permission, and most attorneys advise the new buyer to commission their own inspection rather than relying on a prior report that no longer carries the same legal standing.
How recent should the inspection be?
If a home has been off market for more than six to nine months, or there have been significant storms or seasonal changes since the prior report, a fresh inspection is the safer call. Roof damage, water intrusion, and HVAC performance can shift in a single hard winter or storm season, and the older report stops being a reliable picture of the house.
