Don’t neglect that maintenance 😬 Seriously though—plan to change your filter every 3 months for best results

Zonolite is a brand of vermiculite insulation found in older attics from the 1940's - 1980's. Much of it was produced from vermiculite mined in Libby, Montana, where the deposit was contaminated with asbestos.

Because of this, Zonolite has a significant likelihood of asbestos contamination and should be treated as potentially asbestos-containing unless properly assessed.

It isn’t necessarily hazardous when left undisturbed—the primary concern is disturbing the insulation and releasing fibres into the air.

Just another reason why the attic is an important part of a home inspection

Double-Tapped Breakers

Not as cool as it sounds 😂

A “double tap” simply means two wires are connected to a single breaker terminal.

Is it a big deal? Usually not — but it depends on the breaker.

Some breakers, including certain Square D models, are specifically designed and rated to accept two conductors. In that case, there’s nothing wrong with it.

Most breakers, however, are designed for only one conductor. When they’re double tapped, the wires may not be properly secured, which can lead to a loose connection and overheating.

Fortunately, when it is a defect, it’s typically a straightforward repair for a licensed electrician.

Bottom line: Two wires on one breaker doesn’t automatically mean there’s a problem. The breaker and how it was installed matter. ⚡🏠

🏠 How long do the major systems in your home actually last?

Nothing lasts forever, but knowing the typical lifespan of your roof, furnace, windows, plumbing and septic system can help you plan ahead and avoid surprises.

These are general averages, not expiration dates. Quality, installation, maintenance and environmental conditions all play a role.

Regular inspections and preventative maintenance can go a long way.

Curious what vermiculite insulation looks like?

Here's an example from an attic inspection.

Vermiculite may contain asbestos, but not all vermiculite does. The only way to know is through laboratory testing.

If testing confirms it does not contain asbestos, it is generally considered safe to leave undisturbed. If asbestos is present, avoid disturbing it and consult a qualified asbestos professional before any renovation or removal.
