We looked at hundreds of customer reviews across various sites like Yelp, Google, Facebook, and Houzz, and compiled a list of the most common mistakes and regrets. Ultimately, they fell into these 8 basic categories.

We’ve compiled the list here and added some advice on how to avoid them so you can learn from other people’s mistakes and not make them on your own!

Remember, there’s no ‘Undo” button for Remodeling

Once a project is complete, it is very expensive and time-consuming to make changes. Most people cannot afford to do things over, so it pays to get it right the first time.

Spending time in the design and planning process with experienced professionals is the best way to get lasting results.

8 Remodeling Mistakes and How to Avoid them

#1: Starting Before You’re Really Ready

“Due to his poor planning, in the first 9 weeks of the project there were 26 days where there was absolutely no work done.” — Angi’s List Review, Missouri

Excitement is great. But starting demo before your plan is locked down and materials are on site? That’s a fast track to delays, stress, and extra costs.

Potential Cost: $4K–$8K in labor reschedules, project downtime, and material reorders

Potential for delays and frustrations: Very high

How to Avoid It:

• • Start with a detailed Scope or Work and List of Materials. Create a set of plans that clearly show the layout and details like electric fixture locations.
• • After you sign off on the design, labor scope and materials list everything should be ordered right away.
• • As materials arrive they should be inspected for damage and make sure they are the right color, size etc…
• • Don’t start demo unitl all materials have arrived or you have a guaranteed arrival date with tracking info.

#2: Not Understanding Your Estimate

“We didn’t realize that we had to order all the materials and pay for permits separately…” — Angi review, Indianapolis

Contractor bids and estimates can be hard to understand. This is a top source of misunderstandings and even lawsuits.  That “great price” can balloon fast when the real costs show up later.

Potential Cost: $6K–$10K in hidden costs

Potential frustration: Very high

How to Avoid It:

• • Review estimates in person with your contractor and ask lots of questions.
  • Don’t accept over simplified estimates. 1 or 2 pages is not enough detail for a bathroom remodel
  • Ask if design, material selection, material ordering and storage, daily cleanup, permits, and project oversight are all included.
• • After you approve the estimate there should a design or project development process to create a final, fixed price proposal with all the details.

#3: Hiring Inexperienced Designers or Non-Specialists

“They recommended beautiful tile for our bathroom, but we were told it wasn’t even rated for wet areas. Total bummer.” — Houzz , Atlanta designer

There is decoration and then there is design. Both are important but design is very important when remodeling a kitchen or bathroom.

Kitchen and bath projects require deep knowledge of plumbing, layout, ventilation, and building codes. The wrong designer can leave you with selections that aren’t safe—or up to spec.

Potential Cost: $Unlimited. If the deisgn is not done well the whole project could be wasted. 

Potential Frustration: Very high

How to Avoid It:

• • Look for a designer certified by the National Kitchen and Bath Association (NKBA)
• • Ask how many kitchen or bath remodels they’ve completed
• • Ask for detailed product specs in the materials list

#4: Designing for Pinterest, Not Your Daily Life

“The dishwasher is on the other side of the island from the sink. Every time I wash dishes, I have to drip across the floor to load it.”

When planning a home remodel a space that looks great in a post doesn’t always live well in real life. If your kitchen’s gorgeous but you have to walk across it for a fork, that wears on you fast.

Potential Cost: $12K–$23K in layout regrets or future tweaks

Potential Frustration: Very High

How to Avoid It:

• • Think about how you use the space, your daily routines, and discuss those with your designer.

• • Think about other people who might use the space as well, and what their needs might be

• • Follow NKBA guidelines as much as possible

Mistake #5: Changing Your Mind After Orders Are Placed

“I saw this mosaic tile that was to die for—and of course, I decided to change it after we already ordered everything. It ended up costing way more than I expected, almost $1,000.”

Once materials are ordered, changes get expensive—fast. Even something as small as switching tiles can cause delivery delays, rework, or double shipping.

Potential Cost: $2K–$10K in stacked labor and reorders

Potential frustration: Medium

How to Avoid It:

• • Plan every detail in advance. Right down to the light switches

• • Bring home real samples from the showroom and live with them in your space for a few days—view them in morning light, evening light etc…

#6: Trying to “Phase” the Remodel to Save Money

“We replaced the cabinets and counters but waited to replace the flooring. Unfortunately when we replaced the floors some of the cabinets were damaged. “

Spreading out your remodel can sound like a smart way to manage the budget. But when one phase affects the next—like plumbing, flooring, or wiring—you could end up doubling the work and cost.

Potential Cost: $3K–$8K in redone prep, damaged materials, and return fees

Potential Frustration: Medium

How to Avoid It:

• • Let your contractor or designer know about any future remodels you’re considering—even if they’re years out.

• • A good team will flag what needs to be coordinated now and what could cost you double later if it’s done out of sequence.

#7: Not Budgeting for the What-Ifs

“We opened the wall and found water damage from an old leak. Our contractor says fixing it could cost  thousands…we were already tight on our budget… “

Behind-the-wall surprises are real, especially in older homes in Tallahassee. If there’s no buffer in your budget, every problem becomes a crisis.

Potential Cost: $3K–$15K for repairs, delays, or failed inspections

Potential frustration: High

How to Avoid It:

• • Build in a 10–15% buffer into your budget to cover the unexpected.

• • Talk to your contractor about potential risks and costs

• • Short term, Zero interest financing can be a good way to create  contigency budget if you need it.

#8: Treating the Estimate Like the Final Cost

“The estimate seemed affordable, but we started picking out materials and saw the real layout. The final number was way higher than we expected.”

Estimates are not the same as final costs. Often, after going through the design process the price of things increases. The less accurate the original estimate was, the more severe the increases can be.

Many contractors will give ‘low ball’ estimates to win a job, even if they know prices are likely ot increase in the design process. Or they rely on change orders during the project when they know you have no choice.

Potential Cost: 15 – 40% overages, scope creep, or upgrade stacking

Potential Frustration: High

How to Avoid It:

• • Ask your contractor how accurate their estimates typically are

• • Ask what can change the costs

• • Make sure you get a fixed-price proposal before starting

Plan It Right, and You Won’t Panic Later

The smartest homeowners? Those who made the mistakes figured out what went wrong and wish someone had told them sooner.

So here’s us, telling you sooner:

• • Finalize your layout, selections, and scope before demo even starts

• • Work with a contractor who gives you a clear, fixed-price proposal

• • Make your design decisions early—and stick with them once orders go in

• • Build in room for the stuff you can’t see yet, like surprise repairs or last-minute upgrades

And don’t forget, if you need a little extra cushion? Pre-approved financing can give you backup without the pressure to use it.
