Congratulations on your new home! The excitement of closing day is real—but what you do in the first weekend after closing sets the tone for security, comfort, and confidence in your new space. Before unpacking boxes or decorating, a few small but important upgrades can protect your investment and give you immediate peace of mind. This new homeowner checklist covers the most important tasks to prioritize right away.

Change the Locks: Your Home’s First Security Upgrade

One of the very first things to do after buying a house is changing the locks on all exterior doors. Even if the sellers seemed trustworthy, there’s no way to know how many spare keys exist—from contractors to neighbors to past tenants.

Installing new locks ensures you’re the only one with access. Many homeowners choose smart locks for added convenience, allowing keyless entry, remote locking, and access tracking. It’s a simple upgrade with a major security payoff.

Smoke Detectors: A Critical Safety Check

Smoke detectors are essential for protecting your home and family. During your first weekend, test every detector and replace batteries immediately. If smoke detectors are missing in key areas—inside bedrooms, outside sleeping areas, on each level of the home, and in the basement—install them right away.

This small task can literally save lives and is one of the most important safety steps new homeowners should never delay.

Replace HVAC Filters for Clean Air and Efficiency

Replacing HVAC filters is one of the easiest ways to improve indoor air quality after moving in. Old filters may contain dust, allergens, or pet dander from previous occupants. Fresh filters help your heating and cooling system run efficiently and reduce strain that can lead to costly repairs.

Plan to replace filters every 90 days—or more often if you have pets or allergies—and consider setting calendar reminders to stay on schedule.

Locate the Main Water Shutoff Valve

Knowing how to shut off your home’s water supply is essential. During your first weekend after closing, locate the main water shutoff valve and make sure it turns easily. In the event of a burst pipe or leak, quick action can prevent major damage.

While you’re at it, familiarize yourself with individual shutoff valves for sinks, toilets, washing machines, and other appliances. A few minutes now can save thousands later.

Reprogram Garage Door Openers and Keypads

If your home has a garage, especially one with direct access to the house, reprogramming garage door openers and keypad codes should be a top priority. Old codes may still be in circulation, posing a security risk.

Most systems can be reset easily using the manufacturer’s instructions. This quick step helps ensure that only you control access to your home.

Build a Local Service Provider List

One often-overlooked task for new homeowners is building a local service checklist. Gather contact information for trusted professionals such as:

• Plumbers

• Electricians

• HVAC technicians

• Locksmiths

Introducing yourself to neighbors is also a great way to build community and add an extra layer of security. Neighbors often become the best source for recommendations and support.

Final Thoughts: Start Homeownership with Confidence

The first weekend after closing is about more than settling in—it’s about securing your home and setting yourself up for success. By changing locks, checking safety systems, improving air quality, and learning your home’s essentials, you create a strong foundation from day one.

These simple upgrades don’t require major time or expense, but they deliver long-term comfort, safety, and peace of mind. Welcome home—you’ve officially begun the journey
