I frequently receive this same question: what causes those black verticals stains on walls along the stud lines? To make it short and sweet, the answer is soot, and it's usually caused by candles and thermal bridging.
Have you ever noticed those big cast-iron pipes sticking up out of the ground in various places around the outside of old houses? They're old rainleaders. They took rainwater from the roof and brought it inside the house. From there, the water was either stored in a cistern or exited the house through the sewer system.
It seems like most new flashlights that come out today are simply variations on flashlights that already exist, but every once a while, something a bit new and novel comes across my desk. I simply must try them all. Today, I'll share some information about my newest monster flashlight, keychain light, and headlamp.
Today I'll share my advice on how to become a home inspector. I blogged on this topic back in 2011, and again in 2016, but things change and it's time for another update. I'm writing this because I get a ton of phone calls and emails from people who want to get into the home inspection business. Instead of sharing the first thing that comes into my head during these conversations, I'm putting down all of the most frequently asked questions right here.
I've been ranting and raving about hail-damaged roofs and how messed-up homeowners insurance is for the past couple of blog posts. While digging into this topic with a number of roofing contractors and insurance professionals, I stumbled across some very important information regarding the 15-year mark for roof coverings.
I've given up all hope of trying to assess hail damage to asphalt shingle roofs during home inspections. It's a game. I've looked at dozens of roofs that were in fantastic condition, only to have roofing salespeople come behind me and insist that the roof had hail damage. When I find damage to a roof during a home inspection, I report it. But I don't go around with a microscope trying to determine what may or may not qualify for an insurance claim.
It's no secret that stucco homes have had a ton of water problems during the last few decades. This all started here in Minnesota at the end of the 1980s, but it's not just a Minnesota thing. Newer stucco homes have had catastrophic failures all over the country, and we're still discovering problematic homes on a daily basis throughout Minnesota.
The most common issues we find with overhead powerlines during home inspections are trees rubbing up against them and exposed connectors that present an immediate shock or electrocution hazard. When we find either one of these conditions, we recommend repair. The question that always follows is "Who's responsible for that?"
Inspecting a natural draft water heater vent happens quickly and easily once you know what to look for. Today, I'll show you what to look for when looking at a water heater vent connector. I recently blogged about inspecting water heaters and testing for proper draft at water heaters, and I just couldn't squeeze the part about inspecting water heater vents into those posts. This is really a topic all on its own, so here goes.
When a water heater backdrafts, it's a safety hazard. Homeowners usually don't know they have a problem because a backdrafting water heater will almost never set off a carbon monoxide alarm. A water heater backdrafts when the exhaust gases from an atmospherically vented water heater spill out into the room, rather than safely leaving the house through the vent. Exhaust gases contain carbon monoxide and high levels of moisture, so this is always a condition that should be corrected.
Gas water heaters are a lot like decks, in the sense that most handy homeowners feel qualified to install one. Thanks to these handy folks, we find more installation defects on decks and water heaters than just about any other component in the home, and today I'm going to share how we inspect water heaters.
If you're buying an old house, beware of old water supply pipes; specifically, galvanized steel or lead. These pipes can lead to poor water flow in homes, to the point where you can't even run water in two places at once.
Buying a used house in Minnesota? Here's a rough timeline of potential problems to look out for. It's impossible to make a perfect chart like this because so many of these things are generalities, but I think this chart is a great starting point to knowing what types of issues to look out for.
One of my least favorite chores in the kitchen has always been re-filling the built-in hand soap dispenser at my kitchen sink. Through years of extensive research into this matter, I've discovered that I'm not alone. Approximately 57.3% of soap dispensers in the Twin Cities metro area remain unfilled. Sitting next to the empty soap dispensers, I often find unsightly store-bought bottles of hand soap. Oh, the humanity.
Most air conditioners use one of two types of refrigerant: R-22 or R-410A. Here at Structure Tech, we started paying close attention to this detail during our home inspections about three years ago, because units that use R-22 have become ridiculously expensive to service. The price of this refrigerant began to skyrocket many years ago, and it hasn't slowed down.
To help demonstrate solidarity this week, I'm not sharing any new photos, blog posts, videos, or podcasts. Instead, I'm sharing a special podcast episode that I recorded on Friday with my business coach, Dr. Stephen Crawford.
Governor Walz allowed Minnesota's stay-at-home order to expire yesterday, replacing it with a new order called "Stay safe Minnesota". This new order allows for gatherings to not exceed 10 people. As soon as that order came, our office was flooded with calls from clients who wanted to attend their home inspections.
As I mentioned in last week's blog post, expansion tanks are required when water in a home can't expand back into the water main. This might be caused by a check valve, a backflow preventer, or a pressure regular.
Water heaters come equipped with a temperature and pressure relief valve, also known as a TPRV. This valve allows water or steam to escape from the water heater if the temperature or pressure gets too high.
