Hello again from Sunny Perth. I’m Russell McCarthy, founder and lead building inspector at WA Building Inspections Perth. Over the years, I’ve seen my fair share of dodgy builders, but this recent building inspection in South Perth truly takes the cake. It was a practical completion inspection, and the level of poor workmanship I encountered was so shocking that I found myself laughing in disbelief. In this article, I’ll walk you through the most critical elements of a final house inspection checklist, share some insights from that South Perth inspection, and explain why you really need a professional to catch these kinds of issues.

Why a Final House Inspection is Essential

You might think that following a house inspection checklist is enough to protect your investment. And while it’s a good start, it’s not foolproof. I’ve come across countless homes where the defects were so well hidden that only a trained eye could spot them. The video above from a recent final buuilding inspection in South Perth definitely did NOT have any well hidden defects. Every single defect was so plainly obvious, it was literally laughable. The issues ranged from faulty roof plumbing to improperly installed gutters, and they were all things that could easily be missed by someone without the right experience.

As I went through my normal final house inspection checklist, my sarcasm was pretty obvious:

“Time to look at another roof plumbing job, a nice compliant job. Let’s take a look. No apron flashings, right? No neutral-cure silicone. Those fixings not 40 millimetres apart. Look at the box gutter. It’s 35mm deep, falling in the wrong direction.”

This is why a final inspection before settlement is your last chance to catch these issues before they become your problem.

The Ultimate House Inspection Checklist

While nothing beats the expertise of a professional building inspection in South Perth, having a checklist can certainly help you understand what to look out for during your final home inspection. Here’s a comprehensive house inspection checklist that you can use:

Roofing and Gutters

• Apron Flashings: These should be properly installed to prevent water from seeping into the house. Flashings are essential in directing water away from critical areas like chimneys and roof valleys. Missing or poorly installed flashings can lead to significant water damage over time.
• Gutter Installation: Ensure that the gutters are deep enough (at least 35mm) and sloped correctly to avoid water pooling and potential leaks. The gutters should direct water away from the house foundation. In the South Perth inspection, I found gutters that were not only too shallow but also sloped in the wrong direction, which could lead to major water damage.
• Downspouts: Downspouts should be securely attached and direct water at least 1.8 meters away from the foundation. Check that they aren’t clogged and are properly connected to the drainage system.
• Roof Shingles and Tiles: Inspect shingles and tiles for signs of damage, such as cracks, curling, or missing pieces. These could indicate potential leaks. Also, check for excessive granule loss on shingles, as this is a sign of wear.
• Roof Ventilation: Proper ventilation is crucial to prevent heat buildup and moisture accumulation in the attic, which can lead to roof damage. Ensure that ridge vents, soffit vents, and gable vents are clear and functioning.
• Chimneys and Skylights: Inspect chimneys for cracks or signs of wear in the masonry, and ensure that skylights are sealed correctly to prevent leaks.

Structural Integrity

• Brick Tie-Down Straps: Verify that these are correctly installed and trimmed to avoid water ingress. Poorly installed tie-down straps can compromise the structural integrity of the walls. In the South Perth case, I discovered brick tie-down straps that weren’t trimmed before rendering, which could have easily caused water damage.
• Foundation and Slabs: Check for any signs of cracks in the foundation or slabs. Cracks can indicate settling, which might lead to structural issues. Ensure there are no signs of water pooling around the foundation, which could indicate drainage issues.
• Exterior Walls: Inspect the exterior walls for any cracks, gaps, or signs of moisture intrusion. Pay close attention to the areas around windows and doors, as these are common points where water can seep in. Also, check for any signs of termites or other pests.
• Windows and Doors: Check that all windows and doors open and close properly. Look for gaps that could allow water or air to seep in. Inspect the caulking around windows and doors to ensure it’s intact and not cracked or peeling.
• Decks and Balconies: Inspect decks and balconies for signs of rot, rust, or loose fittings. Ensure that railings are secure and that there is proper drainage to prevent water accumulation.

Interior Finishes

• Walls and Ceilings: Check for any cracks, bulges, or water stains on the walls and ceilings. These could indicate structural issues or water damage. Also, inspect the paint for any signs of peeling or bubbling, which could be a sign of moisture problems.
• Flooring: Inspect all flooring for signs of damage, such as warping, buckling, or gaps between boards. Check for uneven floors, which could indicate issues with the subfloor or foundation. Also, pay attention to the transitions between different types of flooring to ensure they’re smooth and secure.
• Range Hoods: Confirm that range hoods are properly connected and functioning. During the South Perth inspection, I found a range hood that wasn’t even connected, rendering it completely useless. A properly installed range hood is crucial for ventilation and removing smoke and odors from the kitchen.
• Plumbing: Inspect all plumbing under sinks, in bathrooms, and around the kitchen for leaks. Even small leaks can lead to bigger problems down the road, such as mould and water damage. Check that all fixtures, such as faucets, showerheads, and toilets, are functioning correctly and aren’t leaking.
• Electrical Outlets and Switches: Ensure all electrical outlets and switches are properly installed and functional. Test each switch and outlet to make sure they work and aren’t loose. Look for any signs of faulty wiring, such as flickering lights or outlets that don’t hold plugs securely.

Electrical and Plumbing Systems

• Electrical Panel: Inspect the electrical panel for any signs of wear or improper labelling. Ensure that the panel has a main breaker and that all circuits are correctly labelled. Check for any signs of overheating or burn marks, which could indicate electrical issues.
• Wiring and Lighting: Check that all visible wiring is in good condition and that there are no signs of fraying or exposed wires. Inspect lighting fixtures to ensure they’re securely installed and functioning properly.
• Water Heater: Inspect the water heater for signs of rust, leaks, or corrosion. Check that the temperature and pressure relief valve is functioning correctly. Make sure the water heater is properly vented to prevent carbon monoxide buildup.
• Plumbing Fixtures: Make sure all fixtures are properly connected and there are no signs of leaks. Pay special attention to areas around showers, bathtubs, and sinks, where water damage is most likely to occur. In the South Perth inspection video above, I found a particularly concerning issue where water pooled and didn’t drain properly from the shower and bathtub. This kind of problem can lead to serious water damage, mould growth, and structural issues over time. Also, check that the water pressure is adequate in all faucets and that there are no unusual sounds coming from the plumbing system. Proper drainage is crucial to prevent long-term damage, so any pooling water should be addressed immediately.

Safety Features

• Smoke and Carbon Monoxide Detectors: Ensure that smoke detectors and carbon monoxide detectors are installed in all necessary locations, such as bedrooms and hallways. Test each detector to make sure it’s working properly, and replace any batteries as needed.
• Fire Extinguishers: Check that fire extinguishers are installed in key areas, such as the kitchen and garage. Ensure that they are easily accessible and haven’t expired.
• Bushfire Safety: Ensure the property meets all bushfire safety requirements, especially in areas prone to bushfires. This includes checking for adequate fire breaks, non-flammable materials used in construction, and proper placement of fire-resistant landscaping.
• Insulation: Verify that insulation is correctly installed and made of non-flammable materials. Poorly installed insulation can not only increase energy costs but also pose a fire hazard. Check the attic, walls, and crawl spaces for proper insulation.

Appliances and Systems

• HVAC System: Inspect the HVAC system to ensure it’s functioning correctly. Check that the filters are clean and that the system is providing adequate heating and cooling. Also, listen for any unusual noises that could indicate issues with the system.
• Kitchen Appliances: Test all kitchen appliances, including the stove, oven, refrigerator, and dishwasher, to ensure they’re working properly. Check that the dishwasher is securely installed and that there are no leaks around the base.
• Laundry Appliances: Inspect the washer and dryer for any signs of leaks or damage. Make sure the dryer vent is clean and free of lint buildup, which can pose a fire hazard.
• Water Supply and Drainage: Check the water supply lines for any signs of leaks or corrosion. Test all faucets and showers to ensure they provide adequate water pressure and that the water drains properly.

South Perth, Beware of this Dodgy Builder

Let’s return to that South Perth inspection for a moment. The level of incompetence displayed by the builders was astounding. From gutters that leaked directly into the property to a roof that was practically falling apart, it was a disaster waiting to happen. And it wasn’t just the exterior; the interior was just as bad.

“This house has been handed over. This house has been handed over now. It’s already not performing.”

This situation shows the importance of having a professional building inspection in South Perth before you settle into your new home. If I hadn’t caught these issues, the homeowner would have been left with a mountain of problems and no recourse.

Why You Need a Professional Building Inspector

You might be tempted to rely solely on a house inspection checklist, but that’s a risky move. As the South Perth inspection demonstrated, there are countless issues that an untrained eye might miss. And that’s where I come in.

Hiring a professional building inspector like myself isn’t just about peace of mind; it’s about protecting your investment. My detailed inspection reports provide you with the necessary documentation to demand that the builder corrects any defects before you move in.
