The keys are in your hand, the truck is booked, and the excitement is hard to hide. This is also the moment when problems are cheapest to find. Once your furniture is inside, a leaking pipe or a dead outlet becomes your problem to prove, schedule, and often pay for.
So what should you check before moving into a new house? Think of it as a short inspection walk you do while the rooms are still empty. This guide covers the checks that matter most: structure and moisture, plumbing, electrical, heating and cooling, safety devices, locks, and paperwork. You’ll see which problems can wait and which need action before move-in day. The tables below give you a room-by-room checklist, a list of warning signs, and a simple order for tackling repairs. Most checks take about an hour and need no special tools. They won’t replace a licensed inspector, but they can catch the small things that inspectors and sellers sometimes miss.
What should you check before moving into a new house?
Before moving in, check for water damage and mold, test every tap, drain, outlet, and switch, run the heating and cooling, test smoke and carbon monoxide alarms, and confirm that every lock works. Photograph any problems and report them in writing before your belongings arrive.
What is the room-by-room checklist?
| Area | What to check | How |
|---|---|---|
| Kitchen | Taps, drains, oven, fridge space, cabinet hinges | Run water for a few minutes, then look underneath for drips |
| Bathrooms | Toilet flush, water pressure, drainage, caulking | Flush, run the shower and sink together |
| Bedrooms | Windows, outlets, closet doors | Open and close every window, plug in a phone charger |
| Living areas | Light switches, ceiling stains, floor condition | Check each switch and look up |
| Basement or attic | Dampness, musty smell, pests | Use a flashlight in corners |
| Exterior | Gutters, roof edges, doors, drainage | Walk the perimeter and look for pooling water |
Which warning signs matter most?
| Warning sign | Possible cause | Urgency |
|---|---|---|
| Brown or yellow ceiling stains | Past or active leak | High |
| Musty smell | Hidden moisture or mold | High |
| Flickering lights or warm outlets | Wiring fault | High |
| Cracks wider than a coin edge | Possible movement | Medium |
| Slow drains | Blockage or pipe problem | Medium |
| Sticking doors and windows | Settling or humidity | Low |
| Droppings or chew marks | Pests | Medium |
Which safety items should you test first?
| Item | Test | Fix if it fails |
|---|---|---|
| Smoke alarms | Press the test button | Replace batteries or the unit |
| Carbon monoxide alarm | Press the test button | Install one near sleeping areas |
| Exterior locks | Lock and unlock each door | Replace or rekey |
| Window latches | Close and lock each one | Repair or replace |
| Fire extinguisher | Check the gauge | Buy one for the kitchen |
| Gas appliances | Smell for gas and check the flame color | Call the gas provider immediately if you smell gas |
What should you do about utilities and paperwork?
| Task | Why it matters |
|---|---|
| Take meter readings on day one | Protects you from paying the previous owner’s usage |
| Confirm that electricity, water, and gas are in your name | Avoids service gaps |
| Locate the water shutoff and breaker panel | Needed in an emergency |
| Collect manuals, warranties, and keys | Prevents hunting later |
| Change your address and set up mail forwarding | Keeps your mail from going astray |
In what order should you fix things?
| Priority | Examples | Timing |
|---|---|---|
| Safety first | Gas smell, bare wires, no smoke alarm | Before you move in |
| Water and moisture | Leaks, damp walls, poor drainage | Within days |
| Security | Locks, windows | Before the first night |
| Comfort | Paint, slow drains, sticky doors | After you settle in |
Frequently asked questions
Should you do a final walkthrough before closing?
Yes. A final walkthrough lets you confirm that agreed repairs were made and that nothing changed since the inspection.
Do you need a professional inspection if you check things yourself?
A home inspector can examine areas you can’t, such as roof condition and electrical panels. Your own check supplements that report and does not replace it.
What if you find a problem after closing?
Document it with photos, review your contract and any seller disclosures, and ask a real estate attorney or agent about your options.
One last thought
Take a phone and photograph everything before the first box comes in. If a dispute ever comes up, dated photos beat memory every time.
