Breathing in asbestos fibers will increase your risk of developing serious diseases, including cancers, asbestosis, and mesothelioma. If you suspect you have asbestos in your home, don’t attempt to remove it because it could be released. Look for signs of damage and call a professional.

It may be tempting to attempt to repair small electrical jobs in your home, but it’s worth paying a professional instead. Reviewed recommends letting “a professional handle electrical systems 99% of the time” because “electricity is one of the most dangerous elements of any house.”

It may be tempting to save money and remove a dead tree in your yard, but it’s worth paying a professional. There’s no way to guarantee a safe landing, which could lead the tree to land on your home, vehicle, or a neighbor’s property, so leave tree surgery to a professional.

HVAC System Installation

Modern HVAC systems are complex, so DIY attempts to install them are likely to be unsuccessful. Improper installations could cause them to perform poorly, driving up your utility bills and voiding warranties, so call a professional instead.

Pesticide Application

While it may be tempting to apply pesticides to your lawn to keep your plants and vegetable patches free from pests, it’s generally a bad idea. Pesticides, particularly insecticides, are also toxic to a range of other wildlife in your garden and your pets and family, so stick to safer alternatives.

Major Plumbing

Minor plumbing jobs are great DIY projects that can save money. A contractor told Forbes Home, “With a few inexpensive tools, even a novice can save big bucks by clearing clogged drains, fixing faucets, and repairing leaks under a sink.” However, major plumbing jobs are often complex, and DIY errors can lead to more expensive repairs, so it’s best to call a professional.

Solar panels are usually installed on a home’s roof and need precise installation to maximize energy capture. Call a professional to maximize their potential and avoid accidents and injuries. Your state may also require professional installation to qualify for tax rebates.

Mold Remediation

Getting rid of small mold patches in your home is a quick, easy DIY fix. The EPA explains that “if the moldy area is less than about 10 square feet (less than roughly a 3 ft. by 3 ft. patch), in most cases, you can handle the job yourself.” However, if the area is larger or you suspect it was caused by sewage, it’s best to call an experienced contractor to do the job.

Sewage Cleanup

If sewage enters your home after flooding or when a drain bursts, it’s important to call a sewage cleanup service quickly. Sewage is dangerous to your family’s health and can cause extensive structural damage to your plumbing system and wider property.

Gas Appliances Installation

Installing a new oven isn’t a DIY job and should always be done by a professional. HomeTowne Energy argues it’s “necessary to hire a trained professional” for gas appliance installations “because incorrectly installed equipment may result in serious risks such as propane leaks.”

Chimney Cleaning

Basic DIY chimney maintenance is possible and can save you money, but a certified chimney sweep should perform a complete clean and inspection every year. Chimney sweeps use tools and techniques most DIY enthusiasts are unaware of to do a thorough job, and they also inspect for structural issues during the cleaning.

Basement Waterproofing

Waterproofing a basement is an important job that, if done improperly, can lead to major structural damage over time. It’s definitely worth it to pay for licensed professionals using professional-grade materials to avoid serious damage to your basement.

Window Replacement

Replacing a window requires precise measurements and installation to ensure proper functionality and energy efficiency. Handling large panes of glass is also risky for an untrained amateur and could lead to injury, so call a professional when you need to replace a window in your home.

Pest Removal

If you spot pests in your home, particularly large animals like raccoons or snakes, it’s important to call a pest removal service. In some states, it may be illegal to remove them yourself. Professionals know how to remove pests safely without harming themselves or the animals, so don’t attempt to do it yourself.

Home demolition is dirty and often dangerous work. It’s essential to leave it to professional builders to avoid compromising the structural integrity of other parts of your home by releasing excessive dust or even dangerous materials like asbestos.
