Don’t DIY This: 6 Dangerous Home Repairs You Should Always Leave to Pros

Every year, thousands of residents nationwide attempt simple home repairs that, while seemingly straightforward, can lead to property damage or severe injury. Understanding when you should invest in a professional can save you not only money, but your life in the long run.

While replacing a cabinet knob or painting over a living room wall makes for a relaxing weekend activity, complex projects are best left to those with the experience and right licensing. By hiring professional help through a trusted Homeservice provider, not only will you feel more secure in your own home, but you can also count on the work being completed up to local building code standards. Here are 6 home repairs that should be left to the experts.

Why Some Home Repairs Become Dangerous

A small problem can be indicative of a very serious situation. For instance, an individual may identify that his overhead light fixture is flickering and he decides to change the light bulb only. However, he may end up realizing that this is a symptom of a much more serious problem, which could be overloaded circuits in the walls.

There are some issues that can be caused by faulty or improper home repairs, which include:

  • Fire outbreak: When sparks arise from faulty wiring, it might reach 1,000 degrees of temperature, which can easily burn the surrounding wood or drywall.
  • Water damage: Pipes that are not properly attached and exposed to pressure will eventually burst, releasing hundreds of gallons of water to flood your house.
  • Insurance issues: If the repair was not up to code, or completed by a licensed professional, your insurance company may refuse to pay for damages resulting from the initial repair.
  • Structural integrity: Unknowingly drilling the wrong support beam could lead to sagging ceilings or floors, or collapsed walls.

As per the National Fire Protection Association, electrical failures or malfunctions are the common causes of residential fires in America each year.

How to Know If a Home Repair Is Urgent

When a homeowner sees these warning signs, they should immediately cease their current activity and vacate the area:

  • A scorched smell coming from an electrical outlet
  • Sparks or burns coming from an outlet
  • Water leaking around or into an electrical panel
  • A smell of natural gas or rotten eggs
  • A ceiling sagging or a large crack forming in a cinderblock foundation

Sometimes, waiting to address an issue can make things significantly harder. For instance, a slow roof leak will not be able to cause any significant damage since only a few droplets of water will drop within the hour. Nevertheless, when one ignores a drip that leaks consistently for six months, poisonous molds start developing, causing the beams and insulation to rot.

The 6 Dangerous Home Repairs to Leave to Professionals

1. Main Electrical Panel and Other High Voltage Wires

The main electrical service panel contains the high voltage wires that deliver electricity to the entire home. These should be left to professionals, as a circuit may still hold a powerful electric charge even when the main breaker is turned off.

Warning signs of an issue: Frequently tripped breakers, a humming sound coming from the panel, or warm outlet covers.

What to do if an issue is present: Turn the main breaker switch off immediately, unplug any sensitive electronics, and call for professional assistance.

Level of Risk: Very high

2. Gas Line Connections and Appliances

Natural gas is extremely volatile, and just one turn of a screw too far can cause a potentially deadly explosion within your home.

Warning signs of an issue: A hissing sound near a gas connection, a sulphur/smell of rotten eggs, or yellow-brown grass above an outdoor line.

What to do if an issue is present: Evacuate the home immediately and call the professional from a safe location. Never use an indoor phone if gas is suspected to be leaking.

Level of Risk: Critical

3. High Pitch Roof and Flashing

Most ladder-related accidents occur when attempting rooftop work, with over 100,000 emergency room visits being reported to the US Consumer Product Safety Commission annually.

Warning signs of an issue: Missing shingles, watermarks on an upstairs ceiling, or damaged flashing around a chimney.

What to do if an issue is present: Place buckets underneath any leaking areas, and never climb on a wet or steep roof. Always use fall arrestment systems when on a roof.

Level of Risk: High

4. In-Wall Plumbing and Sewer Lines

Walls can contain a number of different plumbing lines, which can reach very high pressure when water is running through them. A DIY mistake with a soldering torch or PVC cement can easily lead to an explosion within the walls, damaging insulation, drywall, and potentially other plumbing lines.

Warning signs of an issue: Loss of water pressure in the home, damp or wet drywall, or sewage backing up in basement drains.

What to do if an issue is present: Shut off the main water supply to the home immediately.

Level of Risk: High

5. Structural and Load-Bearing Wall Alterations

Cutting into the wrong wall can compromise the integrity of your roof or upper floors. It is extremely important to determine ahead of time whether the wall in question is a load-bearing structure.

Warning signs of an issue: Sticking doors, slanted cracks along the perimeter of a room, or buckling drywall.

What to do if an issue is present: Call a licensed structural engineer to evaluate the wall before attempting to alter it in any way.

Level of Risk: Critical

6. HVAC Refrigerant and Electrical Servicing

Modern HVAC units operate using high-voltage electrical currents and high pressure refrigerant chemicals, which are controlled by federal law.

Warning signs of an issue: Icy build-up on the copper HVAC lines, cool air coming from the vents, and unusual compressor noises.

What to do if an issue is present: Turn the thermostat off to prevent the compressor from burning out.

Level of Risk: High

What Professionals Check That Homeowners Usually Miss

Professional contractors have the tools and training to inspect all aspects of a repair project and ensure everything is up to code. Many issues that arise from DIY repairs could be prevented if you simply hire the right professional:

  • Code compliance: A licensed contractor will check that all wiring, plumbing, and HVAC are sized correctly, according to local building standards.
  • System tests: Contractors perform a variety of tests to make sure gas lines, electrical, and plumbing lines are completely secure.
  • Pressure testing: This helps contractors verify gas, water, and sewer lines are completely secure.
  • Proper venting: Technicians will make sure that gas water heaters and HVAC systems are properly vented to remove CO fumes from a home.

By selecting a professional from a trusted Homeservice provider, you can feel confident that the work is being done up to all building codes, with the proper inspections completed along the way.

Practical Application: The SAFE Decision Method

When a sudden malfunction occurs, here’s how to respond:

  • S – Stop and Assess the Situation: Are there any warning signs? Is there immediate risk or danger of gas, water, or electricity leaking?
  • A – Avoid Utilities: If you suspect a gas leak, electrical short, or plumbing issue, avoid the gas main, electrical panel, or water shut-off valve.
  • F – Find Other Warning Signs: Are there any signs of damage or scorching? Are there warning smells coming from the vicinity? Is there any dripping water?
  • E – Employ a Professional: If the task requires permits or work on high-pressure gas, water, or electricity, call a professional

What You Can Safely DIY Instead

Instead of DIY jobs requiring permits, experience, or caution, consider these projects:

  • Replace HVAC air filters every 1-3 months
  • Paint walls and interior trim
  • Re-sealing bathtub, sink, or shower caulk
  • Weather stripping doors and windows
  • Testing or replacing batteries in smoke and carbon monoxide detectors twice a year

Decision Checklist Before Picking Up Your Toolbox

Before attempting a repair, ask yourself these key questions:

[ ] Could this job possibly lead to a serious fall or injury?

[ ] Is there an electrical panel or live electricity involved in this project?

[ ] Is there a gas line that could leak during this repair?

[ ] Is there a possibility of causing water damage inside the walls?

[ ] Could this repair void my homeowners insurance policy?

[ ] Do local building codes require a permit for this type of repair?

Rule of Thumb: If you answered “Yes” to any of the above questions, put the toolbox down and call a licensed professional.

Conclusion

Being safe is much less expensive compared to having to fix the problems that have occurred, not only in terms of money but also in terms of the risk to your well-being. Although doing things by yourself may be quite enjoyable and rewarding, it is important to recognize when it is the right moment to stop working in order not to damage anything or harm yourself. When in doubt, it is better to ask for assistance from professionals, especially in high-voltage work, in gas work, and at high roofs.
