New Homeowner? The First-Year Maintenance Guide

The hardest adjustment to owning a home isn't the mortgage — it's realizing there's no landlord to call. When the water heater leaks or the furnace quits, it's on you to know where the shutoff is and who to call. The good news is that the first year is mostly about setup: locating your home's critical systems, learning how they work, and putting a maintenance routine in place before a surprise repair finds you first.

This guide walks you through that first year — what to find, what to check, and what to schedule, grouped by area of the home. Do it in the first few months and you'll trade the anxiety of "what am I forgetting?" for a home you actually understand. Most of it is free; the rest is a few cheap professional visits that head off expensive failures.

First: find your shutoffs and panels

Before anything breaks, know how to stop it. This is the most important hour you'll spend as a new owner.

• Locate the main water shutoff — DIY. Usually where the line enters the house, near the meter, or in the basement. Test that it turns. In a burst-pipe emergency you'll have seconds, and our burst pipe guide starts with this valve.
• Locate the main gas shutoff — DIY. Know where it is and how to turn it, but only shut it in an emergency and let the utility restore it. If you ever smell gas, leave and call the utility.
• Find the electrical panel and label the breakers — DIY. Map which breaker controls what. It saves you in an outage or an electrical emergency.
• Locate individual shutoffs — DIY. Under sinks, behind toilets, at the water heater, and at the outdoor faucets.
• Find the HVAC units, water heater, and their switches — DIY. Know where they are and how to power them down.

Roof, gutters & exterior

Walk the outside of your home with fresh eyes — you'll spot deferred maintenance the inspection may have flagged.

• Inspect the roof from the ground — DIY. Note the shingle condition and roughly how old the roof is. Book a professional inspection if you're unsure — Pro. Learn the habits in our roof maintenance guide.
• Clean the gutters and check downspouts — DIY. Confirm water drains away from the foundation. Our gutter cleaning guide covers the how and how-often.
• Walk the foundation and grading — DIY. Look for cracks and low spots that pool water. Know what fixes cost in our foundation repair guide.
• Check caulking, weatherstripping, and siding — DIY. Seal gaps to cut energy bills and keep water out.

HVAC & water heater

These are your two most expensive systems to replace, so learning to maintain them pays off immediately.

• Find and learn the HVAC filter — DIY. Note the size, buy a few, and set a monthly reminder to check it. This one habit does more for your system than anything else.
• Book a tune-up for the heating and cooling system — Pro. Especially if you don't know its service history. A furnace or AC tune-up now establishes a baseline and catches inherited problems. See our HVAC maintenance guide.
• Locate the water heater and note its age and type — DIY. Check the label; most tanks last 8–12 years, so you'll know how much runway you have.
• Plan to flush the water heater annually — DIY. Our water heater maintenance guide walks through it.

Plumbing & interior

• Check under every sink and around fixtures for leaks — DIY. Slow drips are the most common inherited problem.
• Test the sump pump if you have one — DIY. Pour water in the pit and confirm it runs.
• Locate and clean the dryer vent — DIY. A common overlooked fire hazard in a new-to-you home.
• Learn your appliances — DIY. Find the manuals (or look them up by model number) and note filter and maintenance needs for the fridge, dishwasher, and disposal.

Safety detectors

Never assume the previous owner kept these current.

• Test every smoke and CO detector, and replace old ones — DIY. Smoke detectors expire at 10 years, CO detectors at 5–7. When in doubt, replace them — it's cheap.
• Buy a fire extinguisher for the kitchen and check any you inherited — DIY.
• Note where detectors are missing — DIY. Add them outside bedrooms and on every level.

Build your team and your calendar

Part of year one is lining up the people you'll call before you need them in a panic.

• Find a plumber, an electrician, and an HVAC company you trust — Pro. Vet them calmly now, not during a 2 a.m. emergency. Our guide to hiring a contractor covers checking licensing, insurance, and getting three quotes.
• Set up your maintenance calendar — DIY. Adopt our year-round maintenance schedule so monthly and seasonal tasks never slip.
• Start a home file — DIY. Keep manuals, warranties, service records, and receipts in one place. It pays off at resale and every service call.

Why the first year matters most

New homeowners get surprised more than anyone, because they inherit years of someone else's deferred maintenance without knowing what's been neglected. That's exactly why the setup work above pays off so fast. Not knowing where the water shutoff is can turn a burst pipe into a $3,867-average water damage disaster. Skipping a first-year HVAC tune-up can let an inherited problem grow into a $5,000–$28,000 system replacement that a caught-early repair would have prevented. An un-flushed, unknown-age water heater fails on its own schedule — usually the worst one.

The first year isn't about spending money. It's about knowledge and habits: knowing your home, knowing who to call, and putting a routine in place. Do that, and you spend the rest of your ownership ahead of problems instead of chasing them.

Don't try to do it all at once

You don't need to finish this in a weekend. Start with the shutoffs and detectors — the safety-critical items — then work through the exterior and systems over your first few months, and let the year-round schedule carry you the rest of the way. The goal is a home you understand and a routine that runs itself, not a heroic first weekend.

FAQ

What should a new homeowner do first? Locate and test your shutoffs — water, gas, and the electrical panel — and check every smoke and CO detector. Those are the safety-critical basics that let you respond to an emergency instead of scrambling.

Should I get my new home's systems serviced right away? Yes, especially the HVAC and, if it's older, the water heater. A first-year tune-up establishes a baseline, catches problems the previous owner deferred, and often keeps warranties valid.

How do I find good contractors before I have an emergency? Vet them calmly now: check licensing and insurance, ask for references, and get three quotes on any real job. Lining up a trusted plumber, electrician, and HVAC company in year one means you're not calling the first name you find at 2 a.m.

How much should I budget for maintenance? A common rule of thumb is 1–3% of your home's value per year for maintenance and repairs. Much of the routine upkeep is cheap or free; budgeting protects you when a bigger system reaches the end of its life.
