🏡 WHEN THE GROUND SHAKES, BE PREPARED!

Earthquake preparedness is about more than stocking up on emergency supplies. It’s also about taking steps to protect your home and family from potential hazards.

Did you know that earthquakes can damage natural gas lines, increasing the risk of dangerous gas leaks and fires?

That’s where the Little Firefighter® Earthquake Gas Shut-Off Valve comes in! 🔥

Designed to automatically shut off the flow of natural gas during significant earthquake shaking, this safety device provides an added layer of protection for your home—even when you're not there.

🔧 HOW DOES IT WORK?
When significant seismic activity occurs, an internal mechanism activates, automatically stopping the flow of gas downstream of the valve. No electricity or manual activation is needed!

✅ Helps reduce the risk of earthquake-related gas fires.

✅ Automatically activates during significant shaking.

✅ Provides an added layer of protection for your home.

✅ Works even when no one is home.

📍 Available now in-store in our plumbing department. Please see one of our team members for more details.

Please note: Professional installation is required, and a qualified professional should inspect the gas system before service is restored following activation.

👉 Swipe through our carousel to learn how this innovative safety device works!

POV: You came in for “just one fitting” 😅

Copper can be a little overwhelming if you’re not sure what you’re looking for - but here’s a quick guide to make your next project smoother:

🔧 Couplings - Connect two pipes in a straight line
🔧 Elbows - Change direction (usually 45° or 90°)
🔧 Tees - Split your line into two directions
🔧 Adapters - Connect different pipe types or sizes

💡 Pro Tips: Always double-check your pipe size before you shop - and grab a couple extra fittings … because you will need them.

Whether you’re tackling a repair or a full install, we’ve got the pieces (and the advice) to help you get it done right.

🌧️💨 STORM SEASON IS COMING…
ARE YOU TIED DOWN? 🌪️

When the wind picks up and the rain starts pouring, the last thing you want is your outdoor equipment, supplies, or belongings getting tossed around!

A little preparation now can save you a BIG headache later. 💪

That’s why we’ve got a variety of heavy-duty ratchet straps and tie-down systems to help you secure your gear before the next storm rolls in.

🔩 STORM PREP TIP: Not all straps are created equal! Here’s what to look for:

✅ Working Load Limit: Choose straps rated for the weight of what you’re securing. Don’t confuse breaking strength with working load limit!

✅ Length Matters: Make sure your straps are long enough to properly secure your load without excess slack.

✅ Check Your Straps: Inspect for fraying, cuts, or damaged hardware before every use.

✅ Secure It Before the Storm: Bring loose outdoor items inside whenever possible, and use properly rated tie-downs and secure anchor points for equipment that needs to stay put.

⛈️ Don’t wait until the wind starts howling to get prepared!

Stop by Goodman’s hardware department and explore our selection of straps, tie-downs, and other storm-preparation essentials.

🚚 Delivery and shipping options are available. Please contact us for more details.

🪵 WHAT’S THE DIFFERENCE? PENOFIN BLUE, RED & MAROON

Planning to protect your deck, fence, siding, or outdoor wood furniture? Not all wood finishes are created equal! Here’s a quick guide to help you understand the differences between Penofin’s popular wood finishes.

🔵 PENOFIN BLUE LABEL — Premium Protection
A dependable choice for everyday exterior wood projects. Blue Label features Brazilian Rosewood Oil to help protect wood from moisture while preserving its natural grain, with up to 90% UV protection in pigmented formulas.

🔴 PENOFIN RED LABEL — Ultra-Premium Protection
Offers up to 99% UV protection in pigmented formulas, plus enhanced protection against mildew. It’s a great option for wood exposed to challenging weather conditions.

🟥 PENOFIN MAROON — Choosing the Right Formula
If you’re referring to Penofin’s maroon-labeled Stain & Sealer, this is a different product formulation designed with features such as water repellency and a no-wipe application. Check the exact product label to confirm the formula and recommended uses.

WHICH ONE IS RIGHT FOR YOUR PROJECT?

The best choice depends on your wood species, exposure to sunlight and moisture, desired finish, and the level of protection you need. Remember, the label color identifies the product line—not necessarily the final wood color!

📍 Stop by our paint department and let our paint specialists help you find the right finish for your next project.

We get it. 🌿😂
And for the record, we’re not judging. We’re enabling. 🌸🪴

Come for one plant. Leave with twelve.

Come back tomorrow because you suddenly have the perfect spot for another one. Sound familiar? 😂

Around here, we believe there’s no such thing as too many trips to the garden center.

Besides, we’d start to worry if we didn’t see you! 💚

🌱 Be honest … how many times have you visited the garden center this season? We promise this is a judgement-free zone. 😉
