Essential Guide to Double Brick Houses: Key Do’s and Don’ts for Homeowners

So, you’re thinking about building or renovating a double brick house? Nice choice, my friend. These beauties are like the tanks of the housing world—sturdy, timeless, and built to outlive your grandkids’ grandkids. But here’s the thing: double brick construction isn’t a “set it and forget it” deal. There are rules. Break them, and you might end up with a house that’s more “leaning tower of Pisa” than “forever home.”

Let me guess—you’ve already fallen down a Google rabbit hole of conflicting advice. One site says double brick is low-maintenance; another warns it’s a termite buffet. Who’s right? Spoiler: They’re both kinda right. But don’t panic. I’ve spent years geeking out over bricks (and even more years fixing other people’s mistakes at The Brick Pitt). Consider this your no-BS guide to nailing your double brick project.

Double Brick 101: Why It’s Not Just “Two Layers of Bricks”

First off, let’s clear up the basics. A double brick house isn’t just slapping two bricks together and calling it a day. Nope. It’s two separate brick walls with a gap (we call it a cavity) between them. Think of it like a brick sandwich—except the filling is air, insulation, or sometimes even your hopes of finishing this project on budget.

Why go double brick?

• Durability: These houses laugh at storms, heatwaves, and your neighbor’s kid’s drum solos.
• Thermal mass: Bricks soak up heat during the day and release it at night. Translation: lower energy bills and fewer arguments over the thermostat.
• Resale value: Buyers love ’em. It’s like the housing equivalent of a luxury sedan.

But here’s the kicker: Double brick isn’t idiot-proof. I’ve seen folks skip critical steps (looking at you, DIYers who think YouTube tutorials > hiring pros). Let’s avoid that.

The Do’s: How to Make Your double brick house a Flex

DO: Invest in Quality Materials (No, Cheap Bricks Aren’t a “Hack”)

Double brick is a long-term relationship. You wouldn’t propose on the first date with a dollar-store ring, right? Same logic applies here. Cheap bricks crack. Weak mortar crumbles. And suddenly, your dream home looks like a post-apocalyptic prop.

At The Brick Pitt, we’ve salvaged too many projects where clients tried to cut corners. Trust me: splurge on high-grade bricks and mortar. Your future self (and wallet) will thank you.

DO: Waterproof That Cavity Like Your Sanity Depends on It

Water is the enemy. If moisture gets into the cavity, you’ll get mold, mildew, and a smell that’ll make your guests ghost you. Install a proper damp-proof course (DPC) and use weep holes to let water escape. And for the love of all things holy, don’t block those weep holes during landscaping.

DO: Insulate Like You’re Prepping for the Ice Age

Double brick’s thermal mass is great, but without insulation, you’re basically living in a kiln. Stuff that cavity with rigid foam or batt insulation. Pro tip: Ask your builder about acoustic insulation if you hate hearing your neighbor’s dog bark at 3 a.m.

The Don’ts: Mistakes That’ll Haunt You (and Your Bank Account)

DON’T: Ignore Expansion Joints

Bricks expand and contract with temperature changes. Skip expansion joints, and your walls will crack faster than a dad joke at a comedy club. Place joints every 12 meters—or consult the pros at The Brick Pitt to nail the spacing.

DON’T: Treat Mortar Like Glue Stick

Mortar isn’t just “brick glue.” Use the wrong mix, and your walls will crumble like a cookie in a toddler’s fist. Too sandy? Weak. Too thick? No flexibility. Follow local standards, or better yet, let a pro handle it. FYI, we’ve seen enough DIY mortar disasters to fill a Netflix documentary.

DON’T: Forget About Termites

“But bricks aren’t edible!” Sure, but termites will happily munch on wooden frames, insulation, and that cute porch swing you added. Regular inspections are non-negotiable. IMO, it’s worth scheduling a checkup with The Brick Pitt—we’ve got X-ray eyes for hidden critters.

Maintenance: Yes, You Actually Have to Do It

Double brick might be tough, but it’s not invincible. Here’s your cheat sheet:

• Check for cracks annually: Hairline cracks? Easy fix. Gap wide enough to hide your car keys? Panic (then call us).
• Clean weep holes seasonally: A clogged weep hole is like a blocked artery. Not ideal.
• Repoint mortar every 15–20 years: Mortar ages faster than avocado on a hot day. Keep it fresh.
