That oversight could mean you walk into a
flooded kitchen if the seal on the water dispenser is faulty or the ice
machine springs a leak.
Leaky faucets
To put a home’s plumbing through its paces, all faucets should be
turned on; toilets should be flushed multiple times; and drain
pipes—even if they’re under the house—checked for leaks while the water
is running.
When it comes to sinks, the faucets need to be run long enough to
fill them before draining in order to spot a leaky pipe or drain. In the
shower, an inspector will need to block the drain pan with a washcloth
or rubber jar opener and fill the shower to the top of the “pan” or
floor, The water should sit for 15 to 20 minutes to test for leaks in
the drain, Kraeutler says.
“That also helps spot if the shower pan is faulty, which is a super-expensive fix,” he says.
Another thing: Leaky shower tiles happen when gaps form in the tile
grout or caulk. And they show up only when wet. To simulate showering,
the inspector needs to splash his hands under the water and check the
integrity of grout and caulk.
Cracked sewage and drainage pipes
Home inspections are always limited to what is visible and
accessible, Kraeutler says. So cracks in underground or buried pipes and
drain lines will be checked only if your inspector conducts a camera
inspection.
That in-depth look into your drain will cost you extra. But the
additional few hundred dollars are a drop in the bucket compared to the
thousands you’ll shell out repairing or replacing faulty sewage and
drainage pipes.
Corroded central air conditioning
Did you know that air-conditioning units can’t be tested in certain temperatures?
It has to be at least 55 degrees Fahrenheit outside in order to run a
unit—temperatures lower than that can cause damage to the air
conditioner, Kraeutler says. That means inspections done in cool
temperatures could have an inspector ignoring the AC altogether.
So if it’s too cold to run the unit, ask your inspector how he looks
for potential problems. You’ll want to make sure the inspector examines
all connections and looks for signs of damage, says
Will Hawkins, owner of All Pro Drain in Austin, TX.
And, if the temperature is 55 or higher, make sure the AC is run for
several hours to test the functioning of the unit’s condenser coil.
“We’ve had customers notice condensation or water seeping through the
walls in a few hours [of turning on the air conditioner] or overnight,”
Hawkins says. “And unless the AC is run for several hours, that’s
something a home inspector would be hard pressed to see during his
run-through.”
Dangerous DIY improvements
It might be tempting to spruce up your home with some DIY projects
before putting it on the market. But if those home improvements are
completed with low-quality materials or not installed properly, a buyer
could face an exorbitant—and unexpected—renovation.
A DIY renovation could be dangerous, too. If a basement or attic is
finished without proper permits, electrical and plumbing work might not
be up to code. And that could mean potential damage—or even danger—to
the residents.
Although many home inspectors check for construction permits with the
local municipality, Kraeutler suggests verifying that step isn’t
overlooked.
Damp porches, decks, and balconies
You might not think of decks and balconies as sources of
expensive leaks. But costs of damage can surge up to $100,000, according
to
Bill Leys, owner of Division 7 Waterproofing Consultants and a deck inspector in San Luis Obispo, CA.
“A deck or balcony can also have serious safety issues and be at risk of collapse,” he says.
Asking your inspector about cracks, rusted flashing, and soft areas
around drains can help keep water from seeping into your home.
One final tip: Most home inspections are performed at least two
months before closing. A lot can change in that time—especially if a
house is vacant, Kraeutler says. Consider having a follow-up inspection
the day of (or no earlier than the day before) closing to ensure you’re
not purchasing a money pit.
