11 DIY House Projects to Never Do

DIY projects can save homeowners major sums, but some projects are better left to the professionals. Working with plumbing, heating and cooling systems, gas lines or structural repairs can be very dangerous and require specialized knowledge and expertise.

A few missteps could lead to costly water damage, a fire or serious injury. These 11 DIY House Projects to Never Do: When to Call in the Professionals.

1. Painting

Many homeowners are drawn to DIY projects because they can save money or give a room a quick makeover. But, certain projects require expert knowledge and skill to avoid serious safety risks or damage to your home.

From removing a wall (they make it look so simple on HGTV!) to working with lead paint, a home inspection expert explains the projects that should always be left to professionals.

2. Plumbing

A quick DIY job like mudding and taping drywall may be a doable project for many homeowners, but anything involving plumbing should always be left to the professionals. A faulty faucet or pipes can lead to major issues and even water damage, which can be expensive to fix.

Complex electrical work, sewer repair, removing load-bearing walls, and roof repairs should also be left to the professionals.

3. Electrical

Some projects may look easy, but they could have serious consequences if DIYers aren’t equipped with the proper knowledge and skills. Whether it’s complex plumbing, sewer, electrical, or foundation work, these are usually best left to the professionals.

Wiring upgrades, for example, pose a risk of electrocution and code non-compliance and can lead to residential electrical fires. It’s best to leave this project to a licensed electrician.

4. Heating and Cooling

Many DIY projects are great for personalizing your living space, but some household tasks are best left to professionals. This is especially true for projects that involve working with gas lines or structural repairs.

Tackling these projects without proper knowledge and skills can be dangerous. Plus, it can damage the integrity of your home. This is why it’s important to only tackle work you know you can do well.

5. Gas Lines

Many projects around the house that look easy to do can actually be dangerous if you don’t have the proper tools and skills. For example, tinkering with electrical wiring can result in shocks and fires, while moving gas appliances can cause carbon monoxide poisoning.

If you notice any strange odors, or see dents, cracks or corrosion on gas lines, call your local gas company right away. These types of repairs should only be made by a licensed plumber.

6. Structural Repairs

Many DIY projects look simple enough to tackle, but that’s not always the case. A DIY project that goes wrong can have serious consequences for your home.

If your structural elements show signs of damage, then you need to call a professional to make repairs. This includes walls, slabs, beams and columns. These repairs should never be attempted by a homeowner.

7. Removing Walls

Removing walls is another project that should be left to a professional. It looks easy on HGTV, but this is a task that requires careful planning and can have serious consequences if done wrong. Electrical wires, plumbing pipes, and load bearing walls can all be hidden behind drywall, so it’s best to have a professional do this work.

Taking down walls can create more spacious floor plans and improve airflow, light, and views throughout your home. This is a complex project that should be handled by an experienced contractor.

8. Removing Wallpaper

If you have an old, outdated wallpaper that needs replacing, hiring a professional can save you the time and mess. They can also ensure your walls are properly prepared for the new paper or paint.

This includes removing any residue from previous decorating attempts and washing the wall. This helps ensure the new wallpaper or paint adheres and looks flawless. Prepping the wall can also prevent moisture from damaging baseboards and floorboards.

9. Painting the Ceiling

Paint drips and splatters can ruin floors, furniture and carpet. Vaamonde recommends moving all movable items from the room and covering those that can’t be moved with drop cloths.

For textured ceilings, she suggests using a stain-blocking primer before painting. This prepares the ceiling’s surface for a smooth coat of paint and helps hide flaws like water stains and discoloration from tobacco smoke.

10. Painting the Walls

Painting walls is an easy project that can transform a room. However, it’s important to know how to prep the wall and use proper paint application techniques to get a professional look.

Also, if your renovation requires a permit, it’s best to let the pros handle it. Diving in without all the necessary information could land you in hot water with the city.
