7 Home Renovations You Should Never DIY, According to Experts

Kitchen Updates

Becoming the designer, project manager, and contractor of a kitchen renovation is a huge undertaking. “At first glance, it might seem like a few manageable DIY projects, but it's far more complex than it appears,” says Jordan DeBrincat, vice president of Altree Developments.

Perhaps the biggest challenge is that you have to consider function in your interior design scheme. “For instance, placing the dishwasher right next to the sink may seem like a small detail, but it prevents unnecessary water messes when rinsing and loading dishes," adds DeBrincat.

Bathroom Refresh

The bathroom may be a smaller space, but you shouldn't handle these renovations on your own, either. There are a few minor details that can make a big difference in the long run–especially when it comes to overall function.

“A common oversight is placing the toilet in direct view when the bathroom door is open,” says DeBrincat. “Instead, the door should open toward the vanity, keeping the toilet out of immediate sight. Since bathroom doors are often left ajar, this simple adjustment creates a more appealing and thoughtful layout."

Mechanical, Electrical, and Plumbing

Anything requiring MEP (mechanical, electrical, and plumbing) requires extra caution, as an unprofessional approach can also lead to serious safety issues. “A small misstep with pipes or water lines may cause leaks, water damage, or even flooding,” says Jessii Lee, senior interior designer at Page, an architecture firm.

All in all, if you can’t afford to bring on a professional, you’re not ready for the renovation. “Reconsider any project that involves potentially risking your own safety and your home’s code compliance,” says Kendra Sinclair, a design trends expert at Thumbtack. “Big projects, like rewiring the electricity in your house, really benefit from trained experts. They'll know how to comply with local building codes and regulations.”

Drywall

Drywall isn’t a DIY project unless you have a lot of experience. “While it seems easy, getting the tape and seams smooth is an art,” says interior designer and TV host Mikel Welch. “Improper installation can lead to visible seams, cracks, and an uneven finish that’s tough to fix. Not only does it affect the aesthetics of your space, but it can also impact overall structural integrity."

Structural Changes

Remember, you’re not on a home renovation show. You'll have to live with that open-concept layout that you desperately want, so at least get a design consultation before knocking down any walls.

“It looks like fun to grab a hammer and take your anger out on the wall, but if there's any sort of plumbing or electrical, or if it’s a load-bearing wall, you’re in big trouble,” says Gaby Beyer Padro, a real estate agent with Compass. “Always have a contractor advise on it first.”

Also, if you move forward without a plan, then there's a chance that your property will go down in value. “As an agent, we notice a sloppy DIY project right away, and so does your future buyer,” says realtor Curt Kelliher. “Plus, it makes the buyer ask, ‘What else did they do themselves?’"

Outdoor Investment

Think of an outdoor space as another room in your home, especially if you have an elaborate vision that requires an al fresco kitchen or living room.

“We recommend hiring a professional for an outdoor patio,” says Heather Napier, director of marketing at Backyard Discovery, an exterior furniture and décor brand. “It takes a lot of work before the pavers even go down—from knowing how many inches of ground to remove to leveling the space and ensuring proper installment for drainage."

Napier adds that expert help is especially important if there's any electrical, plumbing, or gas work involved, as incorrect installation can be dangerous. "A patio is a big investment," she says. "Professionals know how to effectively and efficiently install one and ensure problems are avoided.”

High-End HVAC

Finally, renovating an HVAC (heating, ventilation, and air conditioning) system isn’t the time to show off. An experienced technician must be looped in right from the beginning.

“Many homeowners are looking for more efficient ways to heat and cool their homes,” says Keith Bynum, star of HGTV's "Bargain Block." “Today, there are an abundance of products and systems that will help do just that. While some of these systems, like radiant floor heat, are easy enough to install, many others, like geothermal heating and solar arrays, are complex tasks that require a good deal of knowledge."
