You just bought your first home. Congratulations. Now what? As someone who spent years adjusting insurance claims, I can tell you that most big-dollar claims start with something small that got ignored for months. This 1st home checklist is designed to help you find those problems before they turn into claims. I've seen the same patterns over and over: a slow toilet leak, a cracked heat exchanger, a gutter that dumps water next to the foundation. Each of those started as a ten-minute check. This checklist covers the five most important areas every new homeowner should inspect within their first 30 days.
1. Water — The Most Common Claim Source
Start with water. I can't tell you how many claims I've seen from a slow leak that went unnoticed for weeks. Go to every toilet in the house. Remove the tank lid and look inside. Is the water level 1/2 inch below the overflow tube? Is the flapper sealing? Then check under every sink — look for signs of moisture or corrosion. Run all faucets. Listen for drips. This part of the 1st home checklist alone can save you from a $8,000 subfloor repair. Case file #42: a slow toilet leak went unnoticed for six months. The subfloor rotted, and the homeowner faced $8,600 in repairs. That leak was visible from day one if someone had lifted the toilet tank lid.

2. HVAC — The Second Most Expensive Claim
Your furnace and AC unit are the most expensive systems in the house. A neglected furnace can fail on the coldest night, and a dirty AC coil can cost you 30% more in energy. Check the air filter. If it's dirty, replace it. Look at the outdoor unit — is it clear of debris? Listen for strange noises when it runs. This 1st home checklist step is often overlooked, but it's critical. A failed furnace can cost $4,000–$8,000 to replace. I've seen homeowners postpone a $200 tune-up and end up spending $6,000 on a new unit. Also check the refrigerant lines for insulation damage — that can cut AC efficiency significantly.
3. Roof and Gutters — The Silent Water Intruder
Gutters that clog cause water to overflow and pool near the foundation. That can lead to basement leaks and foundation damage. Walk around the house with binoculars and look at the gutters. Are they free of leaves? Is the downspout directed away from the house? Also check the roof for missing shingles or curled edges. This 1st home checklist item is one you can do in 15 minutes. I've seen a $500 gutter cleaning prevent a $15,000 foundation repair. One claim I handled involved clogged gutters that caused water to seep into the basement, ruining drywall and flooring. That claim was over $12,000. Also make sure downspout extensions carry water at least five feet from the foundation.
4. Electrical — Safety Check
Check the electrical panel. Are there any double-tapped breakers? Is it labeled? GFCIs should be in kitchens and bathrooms. Press the test button on each. If it doesn't trip, have an electrician inspect it. This is not something to postpone. This 1st home checklist safety step could prevent a fire. Electrical claims are often smaller but can be deadly. A faulty outlet caused a house fire that totaled a home I inspected. The homeowner had ignored a frequently tripping breaker for months. Also look for outlets that feel warm to the touch — that's a sign of overload.

5. Foundation and Crawlspace
Go into the crawlspace or basement. Look for cracks in the foundation. Horizontal cracks are serious; vertical cracks are often cosmetic. Also look for standing water or mold. A musty smell indicates moisture. This 1st home checklist visit can catch problems early. I've seen a $200 foundation crack seal prevent a $10,000 structural repair. Water intrusion from a crack can lead to mold remediation and structural work. If you see a crack wider than a credit card, call a structural engineer this week. Also check for rotten sill plates — they can allow pests and water in.
6. Smoke and Carbon Monoxide Detectors
This is the fastest check. Are there detectors on every floor and outside sleeping areas? Press the test button. Replace batteries if needed. This 1st home checklist item is free and takes five minutes. I can't count how many homes I've inspected where detectors were missing or dead. It's the cheapest insurance you can buy. Also consider interconnected detectors — if one goes off, they all sound.
7. Pest and Rodent Inspection
Walk around the exterior and look for signs of pests: termite mud tubes, rodent droppings, chewed wires, or holes in siding. Inside, check for frass (sawdust-like termite droppings) near wood trim and listen for scratching in walls. A pest inspection should be part of your 1st home checklist because termite damage often isn't covered by standard homeowners insurance. I've seen a $150 termite inspection reveal $5,000 in damage that could have worsened. If you find evidence, call a pest control company immediately.
A ten-minute check today saves a ten-thousand-dollar call tomorrow. Walk your home with this 1st home checklist. Mark off each item. You'll sleep better knowing your biggest investment is protected.
