What to Expect from Interior Home Renovation Costs

Thinking about remodeling your home? Whether you're upgrading a single room or planning a full renovation, the cost can vary based on the size of your home, the materials you choose, and the complexity of the work. Knowing what to expect can help you plan your budget and avoid unexpected expenses.

The average cost of an interior home renovation ranges from $10,000 to $150,000 or more. A small update, like new flooring or fresh paint, may cost a few thousand dollars, while a full-scale remodel—such as a kitchen and bathroom overhaul—can reach six figures. Prices depend on factors like labor, materials, permits, and structural changes.

In this guide, we’ll break down renovation costs by project type, highlight hidden expenses, and share practical budgeting tips. If you’re planning a renovation, this will give you a clear idea of what to expect and how to make informed decisions.

Interior Home Renovation Costs: Quick Breakdown by Project Type

Before diving into details, let’s get straight to the numbers. Here’s what you can expect to pay for different types of interior renovations.

Full Home Interior Renovation ($50,000 – $150,000+)

If you're remodeling an entire house, the cost will depend on the home's size and the extent of the work. This includes flooring, walls, kitchen, bathrooms, and electrical or plumbing upgrades. High-end finishes and custom designs can push costs even higher.

Kitchen Remodel ($10,000 – $50,000+)

Kitchens are one of the most expensive rooms to remodel.

Basic Upgrade ($10,000 – $20,000)

High-End Remodel ($35,000 – $50,000+)

Offers custom cabinets, stone countertops, premium appliances, and smart kitchen technology.

Bathroom Remodel ($5,000 – $30,000+)

A small bathroom update—new fixtures, paint, and flooring—can cost around $5,000. A full remodel, including a new shower, tile work, vanity, and plumbing upgrades, can range from $15,000 to $30,000 or more.

Living Room & Bedroom Updates ($2,000 – $15,000+)

Custom features like a home theater, gym, or luxury finishes.

Flooring, Painting, and Minor Updates ($1,000 – $10,000+)

If you're just looking to refresh your space, small updates can be budget-friendly. New paint might cost a few hundred dollars per room, while new flooring can range from $3,000 to $10,000, depending on the material.

These numbers are general estimates. The final cost will depend on your home's size, the materials you choose, and labor costs in your area.

Hidden Costs You Need to Consider

Renovation costs don’t stop at materials and labor. Many homeowners run into unexpected expenses that can quickly add up. Before you start, it’s important to budget for these hidden costs to avoid surprises.

Structural and Electrical Upgrades

Older homes often need electrical rewiring, plumbing updates, or structural reinforcements to meet modern safety codes. If your project involves tearing down walls or opening ceilings, you might find outdated wiring, unstable framing, or hidden water damage. These upgrades can cost anywhere from $2,000 to $15,000, depending on the extent of the work.

Permit Fees and Inspections

Many remodeling projects require permits, especially for electrical, plumbing, or structural changes. Permit costs vary by location but can range from $100 to $2,000 or more. Skipping permits may lead to fines and issues when selling your home. Inspections also add to the cost but ensure the work is done safely and up to code.

Mold, Water Damage, or Pest Issues

Hidden issues behind walls or under floors can derail your budget. If contractors discover mold, termite damage, or water leaks, you’ll need to pay for repairs before continuing the renovation. Mold remediation alone can cost $500 to $6,000, while fixing termite damage can run into the thousands.

Material Delivery and Waste Disposal

Ordering materials often comes with shipping or delivery fees, especially for heavy items like cabinets, countertops, and flooring. At the same time, removing old materials creates waste that needs to be hauled away. Dumpster rentals or debris removal can cost $300 to $1,500, depending on the project size.

Temporary Living Expenses

For large renovations, you may need to stay elsewhere while work is being done, adding hotel or rental costs to your budget. If your kitchen is under construction, you may also spend more on takeout and dining out during the project.

These hidden costs can add 10-20% to your total renovation budget, so it’s best to plan ahead.

How to Budget for Your Interior Renovation Without Overspending

Now that you know the potential costs—including hidden ones—it’s time to create a realistic budget. Whether you're doing a small update or a full renovation, careful planning can help you stay on track and avoid financial stress.

Set a Clear Budget and Prioritize

Start by deciding how much you’re willing to spend and break it down by project. If you have a $50,000 budget, consider how much will go toward materials, labor, permits, and unexpected expenses. Prioritize the areas that will add the most value and improve functionality.

Get Multiple Quotes from Contractors

Labor is one of the biggest expenses in a home renovation. To get the best price for quality work, request estimates from at least three licensed contractors. A detailed quote should include labor, materials, permits, and estimated timelines. Be cautious of quotes that seem too low—they may indicate poor-quality work or hidden fees later on.

Choose Materials Wisely

Materials can make or break your budget. High-end finishes look great, but they aren’t always necessary. Consider mid-range alternatives that offer the same durability and style without the hefty price tag. For example:

• Flooring: Luxury vinyl plank (LVP) looks like hardwood but costs much less.

• Countertops: Quartz is a durable alternative to granite with a similar look.

• Cabinetry: Semi-custom cabinets can save thousands compared to custom-built options.

Plan for Unexpected Costs

Even with careful planning, unexpected expenses happen. Set aside at least 10-20% of your total budget for surprises. If everything goes smoothly, you’ll have extra funds for finishing touches.

Consider Financing Options

If you don’t have the full amount saved, there are financing options available:

• Home equity loans or lines of credit (HELOCs) – Use your home's equity to fund renovations.

• Personal loans – Quick approval, but higher interest rates.

• Contractor financing plans – Some companies offer low-interest or no-interest financing for a set period.

A well-planned budget keeps your renovation on track and prevents costly mistakes.

Why Hiring the Right Contractor Matters

Choosing the right contractor is one of the most important steps in a successful renovation. A skilled, experienced professional ensures the job is done correctly, on time, and within budget. The wrong choice, however, can lead to delays, poor workmanship, and unexpected costs.

The Risks of DIY vs. Hiring a Professional

While DIY projects can save money on labor, they’re not always the best option—especially for electrical work, plumbing, or structural changes. Mistakes in these areas can be dangerous and cost more to fix than hiring a pro from the start. A licensed contractor ensures the work is up to code and done right the first time.

How to Vet Contractors for Quality and Transparency

Before hiring a contractor, take the time to research and ask questions. Here’s what to look for:

• Licensing and Insurance – Make sure the contractor is licensed, bonded, and insured to protect yourself from liability.

• Experience and Specialization – Look for professionals who have completed similar projects.

• References and Reviews – Check online reviews and ask for references from past clients.

• Detailed Written Estimates – A reputable contractor provides a clear, itemized quote covering labor, materials, and timelines.

• Communication and Availability – Choose someone who listens to your needs, answers your questions, and provides regular project updates.

Red Flags to Watch Out For

Not all contractors are trustworthy. Be cautious of:

• Extremely low bids – If a price seems too good to be true, it probably is.

• Lack of references or poor reviews – A history of complaints is a red flag.

• No written contract – Avoid anyone who won’t provide a detailed contract outlining the scope of work.

• High upfront payments – Most reputable contractors require a deposit, not full payment before work begins.

Hiring the right contractor saves time, money, and stress. When you work with a qualified professional, you can feel confident that your renovation is in good hands.

Conclusion and Next Steps

Renovating your home is a big investment, but knowing how much it costs and what factors influence pricing can help you plan wisely. Whether you’re updating a kitchen, bathroom, flooring, or adding extra living space, having a clear budget and hiring the right contractor ensures the project runs smoothly. Remember to account for hidden costs, permits, and potential surprises so you’re fully prepared.
