Five Golden Rings of Electrical Safety Electrical is probably the most important part of an inspection: while there is no doubt there is an issue when there is a waterfall in the kitchen or a large horizontal crack in the foundation, electrical issues can be difficult to detect by the untrained eye. Here are five that I always look for: Single strand aluminum branch circuits: Not all aluminum wiring is problematic; it's commonly used for electrical conduction due to its cost-effectiveness and lightweight nature. I also look for Knob & Tube (K&T) although it has largely been removed and replaced over the years. Inspection of Electrical Receptacles: Checking a representative sample for missing grounds, reverse polarity, and signs of arcing, such as burn marks.
Reporting on the status of Ground Fault (GFCI) and Arc Fault (AFCI) Circuit interrupters: Building and Electrical Codes evolve; retroactive changes are rare. In spite of this, I always suggest updating electrical systems to the latest standards. Assessing DIY Modifications: Any signs of makeshift "improvements," like the use of extension cords for permanent power supply, are noted. System Overview: Assessing the entire system for adequate amperage, checking for undersized wires (oversizing is acceptable but wasteful), and ensuring no reasons exist for the power utility and insurance company to refuse service to the home. Six Geese-a-Laying Insulation Tips In older homes, insulation sometimes becomes an issue due to DIY attempts. While modern homes adhere to updated building codes, some retrofits fall short. For instance, in one inspection of an older brick house, the added insulation was carelessly installed, defeating its purpose. Remember, proper insulation traps air in pockets; compressing it renders it ineffective. Wet fiberglass insulation? Only fit for the trash. More insulation is beneficial, but not when compressed to squeeze more in.  This compression will reduce the R-value of fibreglass insulation. Seven Swans-a-Swimming in Plumbing
Plumbing installations by professionals are generally sound, but ongoing maintenance is crucial. Homeowners need to realize that sinks and drains aren't infinite voids. Disposing of inappropriate materials like baby wipes or bacon grease can lead to plumbing issues brewing for years, suddenly surfacing as household disasters. Eight Maids-a-Milking Moisture Concerns Moisture is the ultimate nemesis of homes, fostering rot, mould, and significant damage. The following proactive measures are key:

We are currently renovating one of our three bathrooms: we replaced the shower unit, redid the floors, painted the walls and the next step will be to replace the vanity and sinks. When the installers were putting in the new shower, it was observed that there was a rotted subfloor that needed to be replaced. Not a big surprise or expense, but something that should not be ignored. Today’s blog post is a spotlight on bathrooms and some of the things we home inspectors are looking for.  Something I wish I could do as a home inspector: rip out floors! Water Damage
I’ve said it many times but will repeat again that water is the #1 enemy of homes. Obviously, a bathroom is by design filled with water using fixtures that are valuable, provided they function as intended. I have identified many leaks during home inspections, but surprisingly the bathroom is rarely the cause. This is likely because most homeowners regularly visit the bathroom and can quickly identify and stop a leak. The two most common causes of water damage are:
GFCI Receptacles Ground-Fault Circuit Interrupters are critical safety features that can prevent death by electrocution (water and electricity don’t mix!). Electrical codes have expanded their use throughout the home but the first room they were required to be installed in was the bathroom. Not only do we always check that they are working properly, but they should also be tested monthly by the homeowner/tenant. Ventilation People are often surprised to learn that the kitchen doesn’t require ventilation, but the bathroom certainly does. A fan (or window) is required to remove the high amounts of moisture, especially after a shower otherwise mould and mildew can quickly take root. There is another type of ventilation we look for: waste pipe (DWV) ventilation. One of the clearest symptoms of inadequate DWV ventilation is gurgling toilets and we can advise further steps if this is detected during a home inspection. Shower/Flooring Tiles A home inspector is not an interior decorator and does not focus on cosmetic issues, but cracked flooring or shower tiles are not only ugly but can provide a means for water to flow where it should not be going. We also don’t comment on things like carpet, but an exception is made for both the bathroom and kitchen as neither should ever have carpeted floors. Improper Drainage While I offer and usually recommend a sewer scope inspection to my clients, they aren’t always necessary to detect problems. The biggest issue I see is slow draining sinks and toilets. If all the sinks and tubs in the home are slow to drain, it is likely a system wide problem that a scope can provide more information about. Luckily most drain issues are isolated to one specific sink or tub and it is often the result of hair that catches debris and while gross, is usually not difficult to clear. Be sure to regularly clean your drains to prevent this from happening. Contrary to certain TV shows, a bathroom leak is usually not detected from a waterfall in the floor below but is usually very slow and subtle. As a home inspector I use thermal imaging, moisture meters and of course good old-fashioned senses to help determine if a bathroom requires further attention from a plumber. As a professional home inspector, my journey has been shaped not only by my keen eye for detail but also by my proficiency in collecting and analyzing data. This skill, honed through many years of experience, has allowed me to derive valuable information from the reports I generate. In this blog post, I'll delve into how my data-driven approach has transformed my inspections, enabling me to make informed decisions, identify trends, and avoid baseless speculation. Harnessing the Data Advantage In a previous role, I experienced a dramatic reduction in my workload by applying my data analysis knowledge, which also granted me the time to pursue my dream of becoming a home inspector. Armed with the insights I've gained over the years; I now use data to support my instincts and bolster my assessments with hard evidence and facts. This approach allows me to provide more comprehensive and accurate home inspections. Identifying Trends: Examples from the Field Let's take a look at some real-world examples of how data has enhanced my ability to conduct inspections:
By consistently collecting and analyzing data on these aspects, I've gained the ability to quickly assess whether a home's features fall within typical parameters or if there's something unique to investigate further. This approach not only streamlines the inspection process but also motivates me to delve deeper into rarer building materials, expanding my knowledge base. I can use this information to better inform clients on the site during the inspection process. The Limitations of Data While data is a powerful tool in the home inspection arsenal, it's crucial to acknowledge its limitations. Data should not be used as a shortcut to draw conclusions without thorough examination. To illustrate this point, let's consider a non-related example:  Lots of data, all of it useless! Imagine a casino game of roulette where a screen displays data on past spins, such as the percentage of spins landing on red versus black. This data may seem helpful but is entirely irrelevant because, in reality, the odds of the ball landing on a specific number in each spin never change. It's a constant probability as each spin of the wheel is independent of the last. Bringing it Back to Home Inspections In the world of home inspections, data can reveal statistical trends. For instance, I can share that 3-tab shingles are statistically more likely to have problems than architectural shingles (almost solely based on the fact 3-tab are generally much older), which, in turn, are more likely than metal roofs to present issues. However, the real world is filled with surprises. I've seen homes with old shingle roofs that exhibited no leaks and, conversely, brand-new roofs with leaks. Ultimately, while my knowledge of statistics and data helps me identify trends and streamline my work, it is no substitute for the hands-on inspection process. Home inspections demand a thorough, physical examination of each property, leaving no room for shortcuts or assumptions. In the realm of home inspections, the fusion of expert observation and data analysis is a powerful combination. It empowers inspectors like yours truly to make informed assessments, identify trends, and offer valuable insights to clients. Yet, it's essential to remember that data alone cannot replace the meticulous, on-site examination required to ensure a comprehensive evaluation of a property. The art of home inspection lies in striking the right balance between data-driven analysis and the hands-on inspection experience.
As both a home inspector and a semi-nerd, I always like to collect and analyze data. One benefit of this is that I can identify trends and look for anomalies during an inspection. For example, the most common plumbing DWV (drain, waste & vent) system I see is scientifically known as (C8H8·C4H6·C3H3N)n, better known as Acrylonitrile Butadiene Styrene(ABS) which looks like hard, black plastic pipe. Over 95% of the homes I have inspected contain some amount of ABS. It’s not just a plumbing material either: did you know that all Lego blocks are made of ABS? You can see a small bit of this pipe sticking out of the roof on almost all homes when looking from the street, so this statistic doesn’t surprise me. Probably the second most common thing I see is asphalt roofing shingles and like ABS pipe it provides the best combination of quality and value. Again, probably 95% of the homes I inspect use asphalt shingles, although this number will drop in the future as metal roofs are becoming more popular. There are two types of asphalt shingles: organic and fiberglass, with most now using fiberglass as organic shingles were generally not made after 2006 and completely discontinued in 2011. Now let's take a look at the two major types of asphalt shingles for residential roofs: 3-tab and architectural. I have not begun to track shingle style yet but both are common in Nova Scotia. Three Tab Shingles They are so named because they have three tabs on the bottom part of the shingle. They have a flat, uniform design and look like the picture below. The main advantage of 3 tab is that they are lightweight and generally more affordable. Architectural Shingles These can also be known as dimensional shingles and are thicker, being composed of a more random, textural look that can look more like other materials such as slate and have a somewhat 3D shape. Typically these shingles are more durable and last longer but with the disadvantage of a higher initial cost. In my experience, most homes (my own included) now use this type of shingle.
It's Not Quite THAT Simple
There are also various grades of shingles available on the market. Unfortunately, determining the grade of shingle is beyond the ability of a home inspector but it is important to note there is no such thing as "bad" shingles. I always like to joke how every company has a "good, better and best" but never "crappy, less crappy and mediocre". In this case, the former is a good representation of the products on the market and a quality installation is far more important to a long lasting, leak free roof. I am now entering my third year running an independent home inspection company and what a fun ride it has been! I can now confidently say that every home is different, no two homes are alike and one of the most exciting parts of being a home inspector is discovering something new. It is always fun to see a unique feature of a home and to see things that we previously have only seen during training.
However, there are some things that are the same on every inspection and while no two inspector’s skill or background is the same there are some things every inspector should know. It always comes off as a shock when I tell clients that there are zero home inspection regulations in Nova Scotia, and anyone can legally call themselves a home inspector in a week or two. Here is a sample of some questions a home inspector should be able to confidently answer after every inspection. Does This Home Have Concerning Electrical Issues? While we are not electricians, home inspectors should be able to detect most major electrical issues. They include:
What Are the Major Plumbing Materials? Most homes I inspect use copper pipe to bring service in from the street, cross-linked polyethylene (PEX) for distribution and plastic, and either ABS (black) or PVC (white) for wastewater. An inspector should be aware of materials that may or may not be a concern such as:
Does The Home Have Potential Water Infiltration Issues? There is a common phrase I use which is “water is the #1 enemy of homes” and biggest concern I get called about is moisture and the damage it has caused. A home inspector should know that water has many ways to enter a home and some of the many signs of water damage. Like many home inspectors, I use a number of tools as well as all my senses to look for signs of either active or potential water infiltration into the home. While we don't have X-ray vision and leaks can be very difficult to detect, a home inspector should be aware of the various ways unwelcome ways water can enter a home. These are just some baseline areas that all home inspectors should be able to confidently speak of. While we are generalists, not specialists we should have a strong enough knowledge to identify the majority of home defects. Your inspector should answer these three questions either verbally or in a report. Welcome to Nova Scotia! There has been a recent spike in people who have chosen to make our city home from both across Canada and around the world and it is wonderful to see the vast and growing cultural diversity when walking around town. My son will get to grow up in a community that is much more welcoming of diversity and valuing of inclusion and I am happy to see our city change for the better. However, as a professional home inspector based in Halifax and having grown up on the Dartmouth side of Halifax Harbour, I see a lot of misconceptions about homes in our community. The overwhelming majority of professional home inspectors in the world are in either Canada or the United States and this is not a coincidence. North America is certainly an economically strong region but there is a common misconception that homes are virtually maintenance free. This is FAR from the truth, and I have never inspected a home that did not have at least one issue (yes, even brand-new homes). Homes in North America are NOT Built Like Tanks There is a commonly held belief that houses in Canada are well built using strict building codes. This is only partial correct: while major structural issues (such as catastrophic collapse due to high winds) are extremely rare, modern homes are often built as cheaply as legally possible. This means that engineered components that while affordable, need to be properly installed to be effective and have limited lifespan that can be greatly reduced under certain conditions (like moisture penetration), such as roof and wall components. Unfortunately, on many building sites these can be installed by subcontractors not as familiar with proper installation techniques. We Have Mild Winters (and That’s a Bad Thing) While compared to the world at large we have brutally cold winters, looking at just Nova Scotia we typically have warmer winters than the rest of Canada. This means we usually get 8-10 mini winters with rain and warmer temperatures in the middle. As a homeowner I appreciate the snow being cleared but as a home inspector this is a challenge to work around. One consequence of our weather is that the frequent freeze/thaw cycles can cause significant destruction to homes through the expansion of water as it cools. Once water gets into building cracks, it can quickly cause further damage. This is one reason with Stucco-cladded homes are so rare in our province. Homes are Usually Built as Single-Family (3-4 people) Homes Until recently, it was considered unusual in North America to share a home with another generation or family. Once children reached their 20s, it was commonly expected that they would move out on their own. Today, it is very common to see 6 or more adults living under a single roof. While this is a great way of sharing resources, this is a concern to home inspectors. Put simply, modern homes need to be carefully balanced: HVAC, plumbing and electrical systems that work great in a 2-person household can experience significant issues in an 8+ person household and can experience major problems that never existed before. Beware the Flipped House I have seen many newcomers buying flipped (homes bought, renovated, and quickly resold) houses that I can see have major structural issues. While not all flipped houses are bad, I have seen far too many recent new arrivals pay a premium for homes that still have major and very expensive issues, such as electrical and plumbing problems. Home inspectors as a rule have an overall negative view of flipped homes as many are renovated as cheaply and quickly as possible. Remember, a home inspector is trained and experienced in telling the difference between a cheap cosmetic flip and a high-quality renovation. There is no question that houses are not nearly as plentiful as they should be, but you should still get all the information about your new home before making that financial commitment as it could cost you a lot more in the long run.
