Why a Home Renovation Budget Goes Over — and How to Prevent It
Setting a realistic home renovation budget is the single best way to avoid being blindsided mid-project. Today I’ll give you five reasons a remodel in Austin, Texas goes over budget — and, more importantly, how to prepare a more realistic budget and prevent getting caught with unexpected costs.
Since I started New Creations in 2006, I’ve seen countless people renovate with unrealistic budgets, only to be blindsided by unexpected costs that leave them running out of money before the project ends. Unfortunately, a lot of contractors don’t warn you before it’s too late. I don’t want to see this happen to you.
So why does everyone go over budget during a remodel?
1. Custom Kitchen Remodeling Splurges
“I work hard, so I deserve this,” “While we’re at it…”, “What’s a little more to get the counters we want?” are all common phrases clients use to talk themselves into selecting items over budget. Popular upgrades like soft-close undermount hardware, LED lighting, premium Caesarstone, Lazy Susans, Thermador appliances, and custom cherry cabinets all tempt customers to overspend.
Roy’s Advice:
- Work with your designer to build a budget around your true needs versus wants.
- Talk to your designer and create a budget based on needs and wants.
- Ensure your designer only shows you items in your price range and DO NOT DEVIATE.
- Don’t waste money on a design you can’t afford.
- Be honest with yourself. If you want the best expect to pay the most.
2. Great Room Trend
A great room is created by removing walls between the kitchen and the family and dining rooms. As a result, there are additional costs to “finish out” the ceilings, walls, and floors from the wall removal.
Roy’s Advice:
- Decide whether you want a great room from the very beginning and include it in your project description.
- Understand that opening up a space turns a single-room remodel into a multi-room one.
- Ensure your remodeler is qualified to remove walls and add structural beams.
- Make sure your estimate and service agreement include all new construction finishes — ceilings, walls, and floors — when creating a great room.
- Opening walls exposes unknown conditions, which can lead to additional unexpected work.
3. The Snowball Effect
Remodeling your kitchen will outdate the remainder of your home. Once you start to update other areas, it “snowballs” into remodeling your entire house.
Roy’s Advice:
- Decide the exact scope of your remodel and stick to it. Be specific in the planning and design phase.
- Ensure your contractor provides a line-item estimate and service agreement detailing each product and service by room.
- You won’t realize how much the un-remodeled parts bother you until you’re living with the new work.
- The budgets and timelines on HGTV are not realistic.
- Choose a design-build company that specializes in an outstanding client experience to guide you.
4. The Unknowns
Contractors include contingencies in their agreements to cover costs for any unknowns that arise during construction, such as rusted pipes, rotten framing, etc. The industry average to cover these costs is 5-10% of the project value.
Roy’s Advice:
- During the bidding phase, perform a mechanical analysis where each trade (electrical, plumbing, HVAC, carpentry) examines the job site in person.
- For the most accurate estimate, remove sheetrock where necessary to look behind walls and ceilings, check whether the existing electrical panel is adequate, and locate your gas and water connections.
- Assessing your existing conditions properly minimizes much of the risk of the unknown.
- Plan on a contingency fund for surprises — a professional remodeler can tell you what’s reasonable for your project.
- Select a remodeling firm with a strong reputation for honesty.
5. Save Money and Time
When you tackle your projects together instead of one at a time, the whole process is more efficient.
Roy’s Advice:
- Make a dream list of everything in your home you’d like to remodel.
- If you can, wait until you can afford to do it all at once rather than piecemeal — one coordinated project beats several scattered ones.
- Do the projects together and move out if possible. That way you pull permits once, endure one demolition, have one phase of painting, and so on.
- Ensure your contractor has all materials procured and checked on-site before construction begins.
- Get every trade’s state license number and a copy of the ID for anyone entering your home, and change locks and security codes at the end of the project.
Conclusion
Thanks for reading. The goal of any home renovation budget is the same: to create a forever home you can enjoy with family and friends for years to come. Keep these in mind so you get exactly what you want:
- Splurges: small upgrades add up fast — decide what’s worth it up front.
- Great room: removing walls is worth it, but it adds finishing work.
- Snowball: let your budget dictate the scope, not your emotion.
- Unknowns: plan a contingency fund for what’s behind the walls.
- Do it all at once: one coordinated project beats several scattered ones.
Save yourself the hassle and choose a remodeling company that will guide you the right way.

Frequently Asked Questions
Why do home renovations go over budget?
The most common reasons are upgrade splurges that add up, expanding the scope mid-project (like opening walls for a great room), the “snowball effect” of one new room making the rest look dated, hidden conditions behind walls, and doing projects piecemeal instead of all at once.
How do I set a realistic home renovation budget?
Start with a clear, specific scope, build the budget around needs before wants, insist on a line-item estimate that details every product and service, and set aside a contingency fund for the unknowns a project can uncover.
What is a contingency fund in remodeling?
It’s money set aside to cover surprises found during construction — things like rusted pipes or rotten framing that no one can see until walls are opened. A good contractor helps you plan for it up front.
