The Most Common Remodeling Mistakes Homeowners Make (And How to Avoid Them)

A remodel can completely transform your home — but it can also become stressful, expensive, and chaotic if you don’t plan it correctly. As a designer and former general contractor, I’ve seen homeowners unknowingly make decisions that lead to delays, change orders, and wasted money.

Here are the top remodeling mistakes homeowners make, and exactly how to avoid them.

1. Starting With a Contractor Before You Have a Design Plan

The #1 mistake — by far.

Contractors build.
Designers plan.
You need the plan before the build.

Without:

• Floor plans

• Elevations

• 3D views

• Material selections

…your contractor is estimating blindly.
This leads to unexpected costs, confusion, and rework.

2. Not Taking Proper Measurements

Incorrect measurements = disaster.

Common issues I fix:

• Appliances too large for the space

• Cabinet doors hitting walls

• Vanities blocking door swings

• Lighting not centered

• Tile patterns not aligning

• Furniture too big for the room

A professional floor plan solves all of this.

3. Choosing Materials Too Late

If you wait until demo day to choose tile or cabinets, you will experience:
❌ delays
❌ backorders
❌ rushed decisions
❌ mismatched finishes

Material selections should be completed before construction begins.

4. Not Planning the Lighting Layout

Lighting is one of the biggest design mistakes homeowners make.

Poor lighting = cheap-looking remodel.

Plan:

• Recessed lighting

• Task lighting

• Pendant placement

• Vanity sconces

• Under-cabinet lighting

• Dimmer switches

Lighting changes the entire mood of the home.

5. Underestimating the Budget

Most remodels go over budget because homeowners don’t understand:

• Freight fees

• Dump trailer costs

• Permit fees

• Electrical upgrades

• Plumbing code updates

• Trim carpentry

• Drywall finishing

This is why we always include a 10–15% contingency when planning.

6. Rushing the Process

If you try to rush design, you’ll pay for it during construction.

Good design saves time.
Rushed decisions cost time.

7. Not Getting a Full Design Package

Contractors need:

• Floor plans

• Cabinet elevations

• Lighting plans

• Plumbing locations

• Tile layouts

• Material selections

If you don’t have these, the remodel is built on guesswork.
