First-Time Homeowner? Here Is the Maintenance Your House Needs (and When)
Just bought your first home? Here is everything you need to maintain it, organized from most urgent to least. No experience required.
Renting taught you one thing about home maintenance: it was someone else's problem.
The landlord handled the furnace. The property manager sent someone when the water heater failed. If the gutters needed cleaning, you never thought about it because you were not the one who paid when they overflowed.
That changed the day you got the keys to your own place.
Now you are the landlord. Every system in the house is your responsibility. Most first-time homeowners discover this gradually — first a filter that has not been changed in who knows how long, then a water heater making a new noise, then a spring gutters-and-roof inspection that reveals years of deferred upkeep from the previous owner.
This guide will help you get ahead of it. Here is what your house needs, organized from most urgent to least.

The First Week: Safety and Survival
Before you unpack boxes, do these things. They take a few hours and a few hundred dollars at most.
Change the Locks
The previous owners may have given out keys to contractors, neighbors, real estate agents, or people they forgot about. Rekeying the locks is inexpensive ($75–$150 for a locksmith to rekey all exterior locks) and gives you confidence that you control who has access. Alternatively, replace deadbolts yourself for $30–$60 per door.
Locate All Utility Shutoffs
Walk every inch of the house and identify:
- Main water shutoff valve — usually near the water meter, in the basement, or where the water line enters the house. Know exactly where it is before you need it in a leak emergency.
- Individual fixture shutoffs — under every sink and behind every toilet. Test that they actually turn.
- Main electrical panel — open it and label every breaker if they are not already labeled.
- Gas shutoff — if you have gas appliances, locate the main shutoff outside near the meter.
Knowing these locations before an emergency is the difference between a minor incident and a flooded basement.
Test All Smoke and Carbon Monoxide Detectors
Press the test button on every detector in the house. Replace batteries in any that chirp weakly or do not respond. If the detectors are more than 10 years old, replace the units entirely — they have a finite operational life regardless of battery condition.
Install detectors if any are missing: one on every level, one in each bedroom, one near the garage if attached.
Inspect for Obvious Problems
Walk through the house methodically before you start living in it. Look for:
- Stains on ceilings or walls (active or past water leaks)
- Soft spots in floors near bathrooms or under sinks
- Mold or mildew smell in closets, basement, or crawl space
- Cracked or missing caulking around tubs and showers
- Broken or malfunctioning windows and doors
Document anything you find with photos. Some issues are seller disclosure problems. Others are just things to put on your maintenance list.

The First Month: Learn Your Systems
The house has systems — HVAC, plumbing, electrical — and you should understand the basics of each before something goes wrong.
HVAC Filter
Find the HVAC filter, remove it, and look at it. If it is gray and clogged, replace it. If it looks relatively clean, mark the date you inspected it on the filter with a marker and replace it in 1–3 months.
Learn your system: is it a forced-air furnace with AC, a heat pump, a boiler with radiators? Know the brand and model number so when you need a technician, you can communicate clearly.
Water Heater
Find the water heater. Note the year it was manufactured (on the label) and the capacity. Most water heaters last 8–12 years. If yours is approaching the end of its life, you should budget for replacement — a $1,200–$2,500 cost that almost always arrives at the worst time if you are not expecting it.
Check the area around the base for rust or moisture. A water heater that has been leaking often leaves rust stains or mineral deposits on the floor.
Electrical Panel
Open the breaker box and verify every breaker is labeled. If they are not, spend an afternoon mapping them with a helper — one person flips breakers while the other confirms which outlets and fixtures lose power.
Note the panel's age and capacity. An older 100-amp panel in a modern house is often undersized. If you plan any renovations or additions, a panel upgrade ($1,500–$3,000) may be necessary.
Understand Your Foundation Type
Slab, crawl space, or basement — each has different maintenance requirements. A crawl space needs a vapor barrier and adequate ventilation. A basement needs a functioning sump pump if it is in a wet region. A slab is relatively low maintenance but any plumbing problems beneath it are expensive to access.

The First Season: Exterior and Weather
Your first full season in the house is when you learn its quirks. Take notes.
Gutters
If you move in during fall: clean the gutters before winter. If you move in during spring: check that gutters came through winter intact and clean any debris. Gutters that overflow direct water against your foundation. Over years, that water causes settlement, cracks, and basement moisture problems.
Check that downspouts discharge at least 4–6 feet from the foundation. Add downspout extensions if they drain too close.
Weatherstripping and Air Sealing
Walk around every exterior door and window. Look for daylight at the edges. Feel for air movement on a windy day. Worn weatherstripping wastes energy and lets moisture in.
Replacement weatherstripping costs $10–$30 per door and takes under an hour to install. Caulking windows costs under $20. These are among the highest-ROI home maintenance tasks for new homeowners because they pay back in lower utility bills immediately.
Exterior Grading
Stand outside after a heavy rain and watch where the water goes. It should flow away from the house in all directions. If it pools against the foundation, that is a problem. Grading corrections often involve nothing more than adding topsoil against the foundation to redirect water away — a $100–$300 DIY project in straightforward cases.

The First Year: System Inspections
Before your first year is out, get professional eyes on the major systems. You want a baseline understanding of their condition.
HVAC Tune-Up
Hire an HVAC technician to service the system. For a forced-air system: expect coil cleaning, electrical inspection, refrigerant check, and filter replacement. Cost: $100–$200. This establishes the condition of the system and gives you a technician you can call when something fails.
Roof Inspection
Have a licensed roofer inspect the roof. Even if the inspection report from your home purchase was recent, having your own roofer assess it gives you an independent opinion and a relationship with a contractor before you have an emergency. A basic inspection costs $150–$300. They will tell you the age of the shingles, any areas of concern, and estimated remaining life.
Plumbing Inspection
Consider having a plumber flush your water heater (if it has not been done recently), inspect accessible supply and drain lines, and check the water pressure. High water pressure (above 80 PSI) stresses pipes and fixtures and can be corrected with a pressure-reducing valve.
Pest Inspection
A pest inspection by a licensed exterminator will identify active infestations (termites, carpenter ants, rodents) and conditions that attract them. In most regions, an annual pest inspection costs $100–$200 and is far cheaper than treating an established infestation.

Building Your Maintenance Routine
After the first year, maintenance becomes a rhythm rather than a discovery process. You know your systems. You know which tasks are seasonal and which are monthly. You know which contractor to call and what the normal state of things looks like.
The challenge is that rhythm requires consistent reminders. Most people maintain good habits for a few months, then life gets busy, and six months later they realize they skipped three filter changes and never cleaned the gutters.
The solution is a system. Sign up for FixReminder and set up recurring reminders for every task: monthly for HVAC filters and detector tests, quarterly for gutters and dryer vents, annually for water heater flushing and HVAC service. You will get an email when each task is due. That is it.
A spreadsheet can work. A whiteboard can work. A reminder app can work. What does not work is relying on memory when you have a job, a family, and a hundred other things demanding attention.

Frequently Asked Questions
What should I do first after buying a house?
The first week priorities are: change the locks, locate all utility shutoffs (water main, electrical panel, gas), and test every smoke and carbon monoxide detector. These are safety-first actions that should happen before you start unpacking.
How much does home maintenance cost per year for first-time owners?
Budget 1–2% of your home's value annually. For a $350,000 home, that is $3,500–$7,000. The first year often costs more because you may be catching up on deferred maintenance from the previous owner plus establishing service relationships with contractors.
How do I know when my systems need replacement?
Age and condition together tell the story. HVAC systems last 15–25 years; water heaters last 8–12 years; roofs last 20–30 years depending on material. A professional inspection at the time of purchase — and annually thereafter — will give you a reliable remaining life estimate so you can budget rather than react.
What is the biggest maintenance mistake first-time homeowners make?
Waiting for something to break. Preventive maintenance is a mindset shift: you are not fixing problems, you are preventing them. A $15 HVAC filter prevents a $3,000 service call. A $150 gutter cleaning prevents $5,000 in foundation damage. The work feels unnecessary when nothing is wrong — until it becomes necessary and expensive.
Is a home warranty worth it for a new homeowner?
Maybe. Home warranties cover repair and replacement of major systems and appliances, typically for $400–$700 per year. They add value on older homes with aging systems. They add less value when systems are newer and well-maintained. Read the exclusions carefully — many warranties exclude conditions caused by deferred maintenance, which is exactly when you need coverage most.
Do I need to hire professionals for all maintenance tasks?
No. Many tasks are straightforward DIY: replacing HVAC filters, testing detectors, cleaning gutters, replacing weatherstripping, and lubricating garage doors. Reserve professionals for anything involving electrical panels, gas lines, roofs, or HVAC refrigerant. A good rule: if a mistake would cost more than hiring a professional, hire the professional.
