12 Home Repairs Virginians Are Told They Need That Rarely Matter

A home inspector runs a flashlight down a thin crack in a Lynchburg basement wall and writes one line about it.

By the weekend, three companies in Virginia have called about that crack.

Two say “structural” before anyone has measured anything, and the third says to watch it and call back in the spring.

These are the home repairs Virginians are told they need that rarely matter.

Note: This is general information, not legal advice. Virginia’s contractor rules and cancellation deadlines are subject to change, so confirm the current details with an attorney.

1. Cleaning Your Air Ducts

Many duct cleaning companies sell the job as basic upkeep, a chore careful homeowners supposedly book every few years.

Duct cleaning has never been shown to prevent health problems, according to the Environmental Protection Agency (EPA), which recommends cleaning ducts only as needed.

Needed is a short list.

It means visible mold in the ductwork, rodents or insects living in there, or so much debris that dust blows into the room.

EPA prices the work at $450 to $1,000 per system, worth holding up next to the number on a mailer.

A Chesterfield County split-level with clean registers and no mildew smell gains nothing from the visit.

2. Roofs Sold From the Driveway

A line of summer storms crosses Hampton Roads, and the crews follow it street by street.

Virginia’s Department of Professional and Occupational Regulation (DPOR) warns about those door-to-door offers, and says most contracting work or bids over $1,000 calls for a state license.

Ask for the number.

DPOR runs a free license lookup, and staff answer the same question at (804) 367-8511.

Shingles that lost tabs in a straight-line wind do need repair, and your insurer sends an adjuster to price the work.

What rarely matters is the full replacement a stranger recommends without ever climbing up there.

Clawing money back is slow, since Virginia’s Contractor Transaction Recovery Fund pays only after you win a court judgment and try to collect on it.

3. Remediating Whole-House Mold

Mold turns up in a lot of Tidewater crawl spaces, and the quote that follows can carry five digits.

Much of that work sits above EPA’s own threshold. If the moldy area covers under about 10 square feet, roughly three feet by three feet, most homeowners can clean it themselves.

Two carve-outs come with that. EPA says to hire a professional when the water came from sewage or other contaminated water, and to check with a doctor first if anyone in the house has asthma, allergies, or another health concern.

Then fix the water.

Clean the mold and leave the leak, and the same wall grows the same mold by fall.

Whole-house remediation earns its price after a burst pipe or a flood, not after a flashlight found mildew on a joist.

4. Waterproofing a Damp Basement

Damp shows up on a Fairfax County basement wall in March, and by April three companies have quoted an interior drain, a sump pump, and a matching contract.

Nobody looked at the gutters.

Water standing against a foundation after a Shenandoah Valley downpour is a drainage problem before it’s a waterproofing problem.

University of Minnesota Extension says to do the easy, low-cost things first: Slope the soil away from the house, fix the gutters, and run downspouts at least four feet out.

Those fixes often solve it.

Groundwater pushing up through a slab every spring is a different story, and that problem earns a drain and a pump.

5. Fixing a Hairline Crack

A hairline crack shows up in the block foundation of a 1950s Lynchburg rancher.

Is it a problem?

Usually not.

Concrete shrinks as it cures, and cracking is inevitable in slabs and foundation walls, says the International Association of Certified Home Inspectors.

Two patterns change that answer, and both can look thin.

A crack running sideways across a block wall is a sign the soil outside is pushing in.

A wall that has started to bow or lean inward is that same warning further along.

Either sign means a structural engineer, not a repair company with a financing plan.

So does a crack that appeared overnight, keeps growing, or comes with sticking doors and uneven floors.

Everything else gets a pencil mark at each end, a date beside it, and a look again in spring. If the marks haven’t moved, you have your answer.

6. Radon Mitigation Sold Before Testing

Radon is the repair nobody should talk you out of, which is exactly why some companies sell the fix before a single test runs.

The Virginia Department of Health counts 46 counties and 15 cities in the federal high-risk zone.

Test first.

EPA calls radon the number one cause of lung cancer among nonsmokers and sets its action level at 4 pCi/L, or picocuries per liter, the unit a test kit reports.

Lower readings still count, and EPA tells homeowners to consider fixing a house that lands between 2 and 4 pCi/L.

Skip the system quoted before anybody tested, or sold on a reading the seller took and read alone.

Virginia law requires radon testers and mitigators to hold national certification, worth confirming before anyone drills.

7. Red-Tagging Your Furnace

A cheap furnace tune-up before the first Blacksburg cold snap is sometimes a sales call in a company polo.

The move to watch is the cracked heat exchanger, where a technician red-tags the furnace, shuts it down, and quotes a replacement on the spot.

Leave it off.

Running a furnace with a crack in question isn't worth the gamble, so leave it down and call a second company with no stake in the first quote.

A cracked heat exchanger can leak carbon monoxide, nobody can patch a crack, and a furnace with a confirmed crack does need replacing.

If a carbon monoxide alarm sounds, everybody goes outside to fresh air first, and then the call goes to 911, never to the company that red-tagged the furnace.

Ask for a photo of the crack and a second report before anybody sells you a furnace.

8. Replacing Every Window

Window salespeople price a whole house at your kitchen table, and the savings math always lands just right.

The federal ENERGY STAR program puts the payoff at up to 13 percent of a household's energy bills, and that figure describes certified windows replacing single-pane glass.

That's the ceiling.

A 1990s house in Prince William County already has insulated glass in every opening, so you save far less while the price stays the same.

Homeowners replace windows for good reasons.

Rot, fogged glass, windows painted shut for decades, and a bedroom window nobody could climb out of in a fire all qualify.

Chasing a heating bill doesn't belong on that list.

9. Sealing Your Driveway Yearly

Driveway sealing comes with a story attached, and consumer agencies have heard it for years: A crew has leftover material from a job down the road and can do your Culpeper driveway cheap, today, in cash.

EPA's fraud alert describes crews that show up unsolicited, use watered down material, and leave work the agency calls poorly done, unfinished, or unnecessary.

The script never changes.

Sealer is a surface coating, so it does nothing for a base breaking up underneath, and a yearly coat mostly darkens a sound driveway for a season.

An older asphalt driveway does benefit from sealing now and then, on a schedule you set.

And if a signature already happened on your porch, you can cancel until midnight of the third business day after signing, under Virginia's home solicitation law.

10. Topping Your Trees

After a storm drops limbs across a Blue Ridge yard, one of the easiest sales is topping, cutting the crown to stubs so the oak "won't come down on the house."

The Virginia Department of Forestry tells homeowners to say no to tree topping, and to have a certified arborist look at the tree instead.

Topping doesn't help.

A topped tree pushes out fast, weakly attached regrowth, which is the wood that snaps in the next thunderstorm.

Hazardous limbs are another matter.

A branch hanging over the driveway, a split trunk, or a trunk leaning at the roofline all deserve a certified arborist, and sometimes a removal.

11. Adding a UV Lamp

The add-on that rides along with an air conditioning service call is the UV lamp in the air handler, sold to kill mold and clean the air in every room.

Household units have limited effectiveness against bacteria and mold, EPA says, since that job takes far more exposure than a lamp in a duct delivers.

Dead spores still set off allergies, so the lamp undoes nothing already sitting in the system.

It's an expensive nightlight.

What helps through a Richmond August is duller: Clean filters, humidity held down, and a coil somebody has washed this decade.

12. More Attic Insulation

Some insulation crews quote blown-in attic work from the porch, before anyone opens the hatch.

The check takes a minute. ENERGY STAR says insulation level with or below the attic floor joists means you need more, and joists you can no longer see mean you probably have enough, where another layer may never earn its cost back.

Look at the joists.

R-value measures how well insulation slows heat, and a tape measure gets you there: Measure the depth in inches, then multiply by about 3.2 for fiberglass batts or 3.7 for loose cellulose.

Twelve inches of cellulose in a Manassas attic comes to roughly R-44, against the R-60 the Department of Energy (DOE) recommends at the top of its range.
