You check the smoke alarms twice a year. You change the furnace filter every three months. Good. But last week, your neighbor found a puddle spreading from the washing machine into the hallway. The floor joists were soft. The repair estimate? $4,200. Her insurance adjuster said the damage fell under “ongoing maintenance,” not a sudden event. The claim was denied.
That denial happens more often than people realize. According to a 2026 J.D. Power study of homeowner claims satisfaction, 23% of denied claims involved damage that insurers classified as preventable through routine maintenance. That’s nearly one in four.
Your home insurance policy is built on the assumption you’ll keep the place in working order. Let it slide, and you’re the one holding the bill. Here are 12 jobs most homeowners forget — and what happens when you do.
1. The Washing Machine Fill Hose — A $5 Part That Can Cost $10,000
Those braided rubber hoses connecting your washer to the wall look harmless. They’re not. The National Association of Home Builders reports that washing machine hose failures cause more than $150 million in water damage claims annually in the U.S.
Rubber hoses degrade from the inside out. You can’t see the cracking until it’s too late. The burst happens when you’re at work or asleep. Water runs for hours.
What to do about it
Replace standard rubber hoses with stainless steel braided hoses. They cost $15–$25 per pair at any hardware store. Replace them every five years regardless of appearance. Write the installation date on the hose with a permanent marker.
Real claim example: A single-family home in Ohio had a hose burst at 2 a.m. Water damage to the first floor and basement totaled $18,700. The homeowner’s policy covered it, but the deductible was $2,500. A $20 hose would have prevented the entire event.
2. Gutter Cleaning — The One Job That Protects Your Foundation
This sounds obvious, but the data says otherwise. A 2026 survey by Angi found that 41% of homeowners clean their gutters less than once a year. Clogged gutters don’t just cause overflow. They cause ice dams in winter and saturated soil against your foundation in spring.
Water pooling around the foundation is the leading cause of basement leaks. Most standard homeowners policies exclude damage from “earth movement” and “water below the surface.” That includes hydrostatic pressure pushing water through your basement walls.
Frequency and cost
Clean gutters twice a year — late spring and late fall. In areas with heavy tree cover, three times. Professional cleaning runs $100–$250 per visit. DIY with a ladder and gloves costs nothing but time.
Insurance angle: If your basement floods because gutters were clogged for months, the adjuster will likely call it a maintenance issue. AM Best-rated insurers have tightened language around “continuous or repeated seepage” in recent policy forms. Read your exclusions carefully.
3. Refrigerator Coil Cleaning — Your Appliance’s Silent Killer
The coils on the back or bottom of your refrigerator dissipate heat. When they’re coated in dust, the compressor runs harder and longer. A 2026 study by the Appliance Standards Awareness Project found that dirty coils can increase energy consumption by up to 35% and reduce the lifespan of the refrigerator by 2–3 years.
Replacing a refrigerator costs $800–$2,500. Cleaning the coils costs nothing and takes 10 minutes.
How to do it
Unplug the fridge. Pull it away from the wall. Use a vacuum with a brush attachment or a coil cleaning brush ($8 at a hardware store). Do this every six months. Mark it on your calendar alongside the smoke alarm battery change.
Failure mode: Most people skip this because they don’t see the coils. Out of sight, out of mind. But the compressor failure that results isn’t covered by your homeowner’s insurance — it’s a mechanical breakdown, not a covered peril.
4. Water Heater Anode Rod Inspection — The Tank’s Sacrificial Lamb
Inside every glass-lined water heater is a metal rod called the anode. It corrodes intentionally so the tank doesn’t. Once the rod is consumed, the tank starts rusting. A leak follows.
Most homeowners never check it. The result: a 10-year water heater fails at year 7 because the anode rod was gone at year 5.
| Water Heater Type | Anode Rod Lifespan | Replacement Cost (DIY) | New Tank Cost (installed) |
|---|---|---|---|
| Gas, 40-gallon | 3–5 years | $25–$40 | $900–$1,500 |
| Electric, 50-gallon | 4–6 years | $25–$40 | $1,000–$1,800 |
| Tankless | No anode rod | N/A | $2,500–$4,500 |
Check the anode rod every three years. If it’s less than ½ inch thick or coated in calcium, replace it. A socket wrench and a breaker bar are all you need. The water heater manufacturer’s warranty may require proof of anode rod inspection. Keep a log.
5. Attic Ventilation and Insulation Verification
You probably checked your attic insulation once. Maybe never. But insulation settles, and rodents move it. Vents get blocked by debris or nests. The result: ice dams in winter, excessive heat buildup in summer, and higher energy bills year-round.
Ice dams alone cause an estimated $1 billion in property damage annually in the U.S., according to the Insurance Information Institute. Many policies cover the water damage inside the house but not the cost to repair the roof or the gutters damaged by the ice dam itself.
What to look for
Go into the attic on a sunny day. Look for daylight coming through the roof deck — that’s a leak waiting to happen. Check that insulation is evenly distributed and not blocking soffit vents. Ensure bathroom fans vent outside, not into the attic space.
State-specific note: In Minnesota and Wisconsin, insurance companies have begun adding specific exclusions for ice dam damage unless the homeowner can prove the attic was properly ventilated. Check your policy if you live in a snow-prone state.
6. Exterior Caulk Inspection — The Water Entry Point You Can’t See
Caulk around windows, doors, and siding fails after 5–10 years. It shrinks, cracks, and pulls away. Water gets behind the siding and rots the sheathing. You don’t notice until the interior wall shows a stain or the window frame feels soft.
Re-caulking a window costs $5–$15 in materials. Replacing a rotted window frame costs $300–$800. Replacing rotted siding can run into the thousands.
How to inspect
Walk the perimeter of your house once a year. Press on the caulk beads. If they feel hard or brittle, scrape them out and reapply. Use a high-quality silicone or polyurethane caulk — not acrylic latex, which shrinks. Pay special attention to the tops of windows and door frames where water sits.
Insurance reality: Rot is almost never covered. It’s considered a maintenance issue. The only exception is if a sudden event like a storm caused the initial damage that led to the rot. Even then, proving the timeline is difficult.
7. Dryer Vent Cleaning — The Fire Risk You Ignore
Lint builds up in the dryer vent over time. It restricts airflow, makes the dryer work harder, and creates a fire hazard. The U.S. Fire Administration reports that 2,900 home clothes dryer fires occur each year, causing an average of 5 deaths, 100 injuries, and $35 million in property damage.
The leading cause? Failure to clean the vent.
Clean it right
Disconnect the dryer from the vent. Use a dryer vent cleaning kit ($15–$30) with a flexible brush that attaches to a drill. Run it through the entire length of the vent. Do this annually. If your dryer takes more than one cycle to dry a normal load, the vent is likely clogged.
Insurer perspective: Some insurance companies now ask about dryer vent cleaning during underwriting. A history of claims related to dryer fires can result in non-renewal. AM Best A+ rated insurers like Amica and Chubb have tightened their guidelines on this.
8. Sump Pump Testing and Battery Backup
A sump pump sits in a pit in your basement. It runs automatically when water rises. Until it doesn’t. A power outage during a heavy rain is the most common failure scenario. The pump stops, the pit fills, and water covers the basement floor.
Standard sump pumps have no battery backup. They’re hardwired into your home’s electrical system. When the power goes out, they’re useless.
What to do
Test your sump pump every three months. Pour a bucket of water into the pit. The pump should turn on and drain the water within seconds. If it doesn’t, the float switch may be stuck or the pump may be dead.
Install a battery backup sump pump or a water-powered backup unit. A battery backup system costs $200–$500 installed. A water-powered backup (uses municipal water pressure) costs $300–$600. Compare that to the average basement water damage claim of $8,000–$15,000.
Coverage note: Many standard policies exclude water damage from sump pump failure unless you have a specific endorsement. Check your policy for a “Sump Pump Discharge or Overflow” exclusion. Add the endorsement if you have a basement. It typically costs $30–$60 per year.
9. Lawn Irrigation System Winterization
If you live in a climate where temperatures drop below freezing, your underground sprinkler system needs to be drained before winter. Water left in the pipes freezes, expands, and cracks the PVC. Come spring, you turn on the system and water sprays from a dozen broken heads.
Repairing a burst irrigation line costs $150–$400 per break. Replacing a full zone can run $500–$1,500. A professional winterization service costs $50–$100.
DIY or hire it out
You can blow out the lines yourself with an air compressor, but you need a high-CFM compressor (10+ CFM at 90 PSI). Most homeowners don’t own one. Hiring a professional is cheaper than replacing broken pipes. Do this before the first hard freeze in your area.
Insurance: Buried pipes that freeze and burst are often covered under your policy’s “freezing” peril, but only if you took reasonable care to maintain heat or drain the system. If the adjuster finds the system wasn’t winterized, the claim may be reduced or denied.
10. Chimney and Fireplace Annual Inspection
You use the fireplace three times a winter. The creosote buildup inside the chimney is invisible from the living room. A chimney fire burns at over 2,000°F and can crack the flue liner. Flames can spread to the roof or walls before you even know there’s a problem.
The Chimney Safety Institute of America recommends an annual inspection by a certified chimney sweep. Cost: $100–$250. A chimney fire can destroy a $30,000 roof and cause structural damage that exceeds $50,000.
What the inspection covers
Level 1 inspection (standard for a clean, well-maintained chimney) checks the interior and exterior of the flue, the damper, and the firebox. Level 2 (required after a chimney fire or property transfer) includes a video scan of the flue interior. Don’t skip the video scan if you bought a house with an existing fireplace.
Insurer view: Some insurers require proof of annual chimney inspection for policies covering homes with wood-burning fireplaces. If you have a claim and can’t produce the inspection record, the claim may be denied for negligence.
11. Garage Door Spring and Cable Inspection
Your garage door opens and closes 1,000+ times a year. The torsion springs and cables bear the entire weight of the door. When a spring breaks, the door slams down. If someone is underneath, serious injury can occur. If a car is in the way, the repair bill includes body work.
Garage door springs have a rated lifespan of about 10,000 cycles. For a typical household, that’s 7–10 years. They don’t wear out gradually — they snap suddenly.
What to check
Listen for squeaking or grinding when the door operates. Look for gaps in the spring coils. If a spring looks stretched or has a visible gap, it’s about to fail. Do NOT attempt to adjust or replace torsion springs yourself — they’re under extreme tension and can cause severe injury. Hire a professional. Replacement costs $150–$350 per spring.
Insurance: A broken garage door is typically covered under your home policy’s “other structures” coverage, but the deductible still applies. A car damaged by a falling door is covered under your auto policy, not the home policy.
12. HVAC Annual Tune-Up — The One That Pays for Itself
Your heating and cooling system works hardest when you need it most. A system that’s 10% less efficient costs 10% more to run. A neglected system breaks down on the hottest day of summer or the coldest night of winter.
An annual HVAC tune-up costs $100–$200. It includes cleaning the coils, checking refrigerant levels, inspecting electrical connections, and lubricating moving parts.
The data
A 2026 report from Energy Star found that regular maintenance can extend HVAC system lifespan by 5–7 years and improve efficiency by 15–20%. Replacing a failed HVAC system costs $4,000–$12,000. A tune-up is 2–5% of that cost.
Insurance link: Some insurers offer a discount for homes with a maintenance contract on the HVAC system. Ask your agent. If a system failure causes secondary damage — like a frozen pipe from a broken furnace — the claim is more likely to be approved if you can show the system was maintained.
Quick Comparison: Cost to Maintain vs. Cost to Repair
| Job | Annual Maintenance Cost | Repair/Replacement Cost (if skipped) |
|---|---|---|
| Washing machine hose replacement | $25 (every 5 years) | $5,000–$20,000 (water damage) |
| Gutter cleaning | $0–$250 | $3,000–$15,000 (foundation repair) |
| Refrigerator coil cleaning | $0 | $800–$2,500 (new fridge) |
| Water heater anode rod | $25–$40 (every 3–5 years) | $900–$1,800 (new tank) |
| Dryer vent cleaning | $15–$30 (DIY kit) | $35,000+ (fire damage) |
| HVAC tune-up | $100–$200 | $4,000–$12,000 (new system) |
The pattern is clear. A few dollars and a couple hours of work each year save thousands in repairs and keep your insurance coverage intact. Your policy is a safety net for sudden, unexpected events. It was never designed to cover neglect. Treat these 12 jobs as non-negotiable, and you’ll sleep better — and keep more money in your pocket.
