The 7 Most Common Mistakes Homeowners Make During a Renovation (And How to Avoid Them)

A home renovation can be one of the most rewarding projects you take on—but it can also be one of the most stressful. While every project comes with some dust and disruption, many of the biggest headaches are preventable. Whether you’re remodeling a bathroom, updating your kitchen, or redoing your whole home, avoiding a few common missteps can save you time, money, and regret. Here are the top mistakes homeowners make during renovations—and how to steer clear of them.

1. Skipping the Planning Stage

Jumping straight into demolition might feel productive, but poor planning can lead to confusion, delays, and expensive do-overs.

Avoid it:

• Start with a clear vision and realistic goals

• Map out your budget, scope, and timeline

• Work with a contractor early to align expectations and logistics

Well-planned projects stay on schedule—and on budget.

2. Hiring the Wrong Contractor

Choosing based on the lowest price—or a gut feeling—can lead to major issues.

Avoid it:

• Check licenses, insurance, and online reviews

• Ask for references and past project photos

• Make sure they communicate clearly and consistently

Your contractor should feel like a partner, not a risk.

3. Changing the Plan Mid-Project

Wanting to swap the tile or move a wall after work has started? That’s called scope creep—and it can drain your budget fast.

Avoid it:

• Finalize all design decisions before construction begins

• Build in time for thoughtful planning up front

• If changes are unavoidable, understand the added costs and delays

Stick to the plan to stay in control.

4. Underestimating the Budget

Many homeowners plan for materials but forget labor, permits, delivery fees, and surprises behind the walls.

Avoid it:

• Build in a 10–20% contingency fund for the unexpected

• Ask your contractor to walk you through a full cost breakdown

• Be upfront about what you’re willing to spend

Being realistic from the start protects you from sticker shock later.

5. Ignoring Permits and Local Codes

Skipping permits to save time or money can lead to fines, delays, and inspection failures.

Avoid it:

• Always check with your city before starting major work

• Use a contractor familiar with Milwaukee’s local codes

• Understand what inspections are required at each phase

It may take extra time, but it’s worth avoiding legal and safety issues.

6. Living in the Construction Zone Without a Plan

Trying to maintain normal life without preparing for dust, noise, and disruption leads to stress for everyone.

Avoid it:

• Seal off work zones and create a “clean zone” in your home

• Cover furniture, remove breakables, and talk to your contractor about daily cleanup

• Consider alternative living arrangements for larger jobs

Plan for the mess so it doesn’t overwhelm you.

7. Focusing Only on Looks, Not Function

It’s easy to get caught up in pretty Pinterest boards—but if your new layout doesn’t work in real life, you’ll regret it.

Avoid it:

• Think about how you use the space daily

• Prioritize smart lighting, flow, and storage just as much as finishes

• Ask your contractor or designer for practical input

Design with your lifestyle in mind—not just the final photos.
