There are a lot of variables in play with these projects, codes to meet, plans to draw, and then sometimes you get into the actual work and have to improvise due to some previously unknown quirk of the house. None take particular skills beyond a solid knowledge of construction, plumbing or wiring, some equipment, and patience. Or, you know, a checkbook.
Plumbing That Goes Deeper Than a Fixture Swap
Replacing a faucet is a true DIY project. Moving drain lines, extending a wet wall, or tying into the main stack is not.
The reason is physics more than skill. Drain systems rely on exact slope, typically, a quarter inch of drop per foot of run, and proper venting to keep sewer gases from backing into the home. Get that slope wrong by even a small margin and you’ll have slow drains at best, standing wastewater and odor problems at worst. Sewer lateral work adds another layer of complexity, often requiring a camera inspection before anyone touches a pipe.
Bathroom and kitchen remodels are where this most often catches homeowners off guard. A homeowner hoping to move a sink or add a second bathroom needs someone who knows how black water and gray water systems interact, and how to tie into existing infrastructure without creating pressure or venting problems. Hiring a local Utah plumber who knows current code requirements means the work gets done right and passes inspection, and that matters when it’s time to sell.
Electrical Panel Upgrades and Rewiring
The panel is not the place to improvise. Homeowners regularly underestimate how tightly regulated circuit breaker panel work is, and for good reason, a wiring error doesn’t always show up immediately. It can sit in a wall for years before it becomes a fire.
Panel upgrades are also frequently required during kitchen remodels when new appliances demand dedicated circuits. This work almost always needs a permit, and permitted work gets inspected. That inspection record is documentation your insurance carrier and any future buyer will want to see.
Load-Bearing Wall Removal
It might seem like open-concept renovations are easy to do based on the renovation television shows. In reality, if you take down a wall and don’t know how loads are distributed from above, you might be stuck with a ceiling that deflects, and door and window frames that no longer close properly. Or, in the worst case, you could be stuck with structural movements that affect the foundation.
Guesswork is not how you identify a load-bearing wall. You have to assess the home’s framing plan if one is available or get a structural engineer in there to suggest solutions. A general contractor and an engineer working together are extra costs upfront, but they are far less of a hit to the budget than having to correct a sagging ceiling.
Gas Line Work
Installing new gas lines is one of the riskiest home projects you can take on. And worse than the installation risk is the cumulative risk of an undetected leak over the long term. A tiny undetectable leak in a joint/splice or at a valve/connection can silently fill a closed space, which is how a lot of houses burn down or people die.
When all the digging and fitting and sweating are done, and the line passes a forced pressure test with soapy water, what was your acceptable outcome? If you’re even going to bring that question up, or need to think about it and try to rank the level of consequence between risking a bypass and just having it done by people who do this for a living, you don’t have the tools to figure out what you’re doing.
Major Waterproofing and Sump Pump Installation
Hydrostatic pressure, which is the force that water applies against your foundation walls and floor, can slowly cause damage for years without you even noticing it, through your basement or crawl space. If it’s on the milder side, surface-level waterproofing products may be able to slow that damage. But if you have real water intrusion, you’ll need proper drainage channels, and may even require exterior membrane work, either way, you might need a sump pump, and it must be the right size to handle your water load.
Installing one without properly sizing it, considering where the discharge will go, and ensuring you have backup power will leave the pump at risk for failure when you need it most. This is also a job you’ll almost certainly need a permit for, and that means hiring a licensed contractor to ensure the discharge meets your local requirements.
The Real Cost of Getting it Wrong
According to Misthub, 63% of DIYers express regret over at least one of their projects, often because the job ended up costing more or being harder than expected. Chances are that figure doesn’t even capture the full scope of regret out there, because those DIYers aren’t obligated to reveal their mistakes until the day of sale.
Competence isn’t the best way to think about taking on jobs like this. Risk is. Professionals carry warranties, insure their work, and pass all necessary inspections, which helps boost your home’s, and its insurance company’s, sense of its value. For DIY projects in these realms, on the other hand, you’re on the hook, even after you sell the place.
Recognizing which jobs to hand off isn’t defeatism, it’s good sense.
