Here’s a number worth sitting with before you plan a remodel. In a 2026 national survey of homeowners who recently renovated, 37% went over their original budget and only 3% came in under. About a quarter never set a specific budget at all. But the most useful finding is buried in the reasons. The overruns rarely traced back to a bad estimate. They came from decisions made after the crew showed up, once the walls were already open.
For a kitchen or a bath, the two most expensive rooms to touch, that gap is the whole ballgame. The estimate gets the attention. The change orders quietly write the real invoice.
Why Do So Many Remodels Go Over Budget?
Most remodels go over budget because of decisions made during construction, not because the first estimate was wrong. In that 2026 survey, among the projects that ran over, 35% of homeowners upgraded to higher-end materials mid-project, 32% ran into complexity they hadn’t planned for, and 31% changed the scope while the crew was already on site.
None of those three are estimating errors. They’re choices. Some are voluntary, some are forced by what’s behind the wall, but all of them land after the number has been set. A quote is only as accurate as the plan it’s built on. When the plan is still half-formed on demolition day, every open decision turns into a live negotiation while paid labor stands in your kitchen. That’s the most expensive moment to be deciding anything.
The Estimate Isn’t Where Budgets Break
It’s tempting to shop remodelers on the bottom-line number and pick the lowest one. But an estimate is just a snapshot of a plan, and a low number often means fewer decisions have been made, or that allowances were set artificially low to win the job. It helps to know what a kitchen or bath remodel typically runs before you start comparing quotes, so you’re measuring against a realistic range instead of the most optimistic one. A quote that quietly assumes stock cabinets and builder-grade tile will always look cheaper than one that reflects the finishes you actually want.
Which Decisions Cause the Biggest Overruns?
Three decisions drive most overruns: upgrading materials after the quote, uncovering hidden problems once the walls open, and expanding the scope mid-project. The survey put hard numbers on them, at 35%, 32%, and 31% of over-budget projects. Two of the three are fully within your control, but only if you settle them before demolition rather than during it.
Upgrading Materials After You’ve Signed
This is the quiet one. You approved mid-grade quartz in the estimate. Then you stand in front of the honed marble-look slab, and it’s suddenly a few thousand dollars more. Multiply that moment across cabinets, tile, fixtures, and hardware, and a dozen small upgrades become a five-figure swing. There’s nothing wrong with wanting the nicer material. The mistake is deciding on it after the budget is locked, one temptation at a time, instead of pricing the finishes you truly want up front.
Scope Creep, One “While We’re At It” at a Time
Every remodel invites the adjacent project. The floor’s already up, so why not run new wiring? The wall’s already open, so let’s move the sink two feet. Each addition sounds reasonable on its own. Together, they’re how a kitchen refresh turns into a first-floor renovation. Deciding whether to remodel one room at a time or take on more at once before the work starts keeps scope a plan instead of an impulse you act on with a saw in your hand.
How Do You Lock Materials and Scope Before Demo Day?
You lock them during the design phase, before demolition, by making every material selection and scope decision on paper first. That means choosing cabinets, counters, tile, and fixtures in the showroom, setting realistic allowances for anything left open, and getting the full scope into a written plan and contract, so construction executes decisions instead of making them under pressure.
This is where a design-build process earns its keep. At Solstice Kitchen & Bath, the design and material selections happen in the showroom in Crofton before a single wall comes down, so you’re comparing the real tile, the real cabinet door, and the real countertop against each other instead of guessing from a two-inch sample and re-deciding on site. Because the people helping you choose are the same team that builds it, designing and pricing the full kitchen and bath remodel up front means each selection gets checked against the budget before it can quietly become a change order.
Put Every Selection and Allowance in Writing
An allowance is a placeholder dollar amount for something you haven’t picked yet, like “tile, $2,500.” Allowances are fine early on, but every one left open on demo day is a future overrun waiting to happen. Before work starts, convert allowances into real selections wherever you can. The Federal Trade Commission’s guidance on hiring a contractor is blunt about the paperwork: get the scope of work, the materials, and the cost of labor into a written contract, and don’t automatically pick the lowest bid. That contract isn’t red tape. It’s what keeps a casual “sure, we can do that” from landing on your final bill unpriced.
What About the Surprises You Can’t Plan For?
Some overruns are unavoidable. The 32% who hit unplanned complexity usually found something real behind the wall: brittle old wiring, hidden water damage, a drain line exactly where the new island was going. You can’t design those away. But you can shrink how often they blindside you with a careful pre-demolition assessment, and you can absorb the rest with a contingency you set aside on purpose.
Set Aside a Contingency Before You Need It
A contingency is money you budget specifically for the unexpected, kept separate from your material selections. Homeowners who set one rarely feel the scramble that the quarter of homeowners with no budget at all describe. When nothing goes wrong, it’s money you simply didn’t spend. When the subfloor turns out to be rotted, it’s the difference between a solvable line item and a stalled job. Decide the number while the plan is calm, not in the middle of an open floor.
A Diagnostic Walk-Through Finds Problems Early
The best way to reduce surprises is to look before you commit. Solstice’s process starts from the functional problem you’re actually living with, the cramped galley or the bath that never dries out, and works back through layout, plumbing, and the likely condition behind the surfaces, rather than starting from a finish you liked online. That whole-space diagnostic won’t catch everything. It does turn a lot of demo-day emergencies into things you already planned for. It also helps to hire a remodeling contractor who keeps the whole plan under one roof, so the person who finds the problem is the same person accountable for solving it.
Frequently Asked Questions
Why do most kitchen remodels go over budget?
Most go over because of decisions made during construction, not a wrong estimate. Recent 2026 survey data found that among over-budget projects, homeowners most often upgraded materials mid-project, hit hidden conditions, or expanded the scope after work began. Settle your materials and scope before demolition, and you remove the two biggest controllable causes.
How much should I budget for the unexpected?
Set aside a dedicated contingency, separate from your material selections, and decide it before work starts. The right amount depends on the age and condition of your home and how much you’re opening up. An older home with original plumbing or wiring warrants a larger cushion. The point isn’t a magic number. It’s having a planned line for surprises instead of scrambling mid-project.
What is a change order?
A change order is a written record of any change to the agreed scope, materials, or price after the contract is signed. It spells out what’s changing, what it costs, and how it affects the timeline, before the work happens. Handling changes this way keeps a casual “can you also…” from showing up as an unexplained charge on your final invoice.
Should I choose all my materials before construction starts?
As many as you can, yes. Every selection left open as an allowance is a decision you’ll make later, often on site, under time pressure, when upgrades are hardest to resist. Choosing cabinets, counters, tile, and fixtures during the design phase lets you price what you actually want and keeps the budget attached to real choices instead of placeholders.
Does a fixed-price quote protect me from going over budget?
It helps, but only for the scope it covers. A fixed price is fixed against a specific plan and specific selections. Change the plan, upgrade a material, or uncover a hidden problem, and the price moves through a change order. A fixed quote built on a vague plan gives false comfort. A detailed one built on finished selections is far more reliable.
Can I avoid surprises behind the walls entirely?
Not entirely, but you can reduce them. A thorough pre-demolition assessment of layout, plumbing, and the likely condition behind your surfaces catches many issues before they become mid-project emergencies. What it can’t rule out, like a rotted subfloor or undersized wiring, is exactly what your contingency is for. The goal is fewer surprises and a plan for the ones that remain.
Is it cheaper to remodel a kitchen and bath at the same time?
It can be more efficient to overlap shared work like permits, demolition, and trade scheduling, but combining projects also raises the total budget and the disruption at once. Whether it saves depends on your scope and how the trades sequence. The safer question isn’t cheaper or not. It’s whether your plan and contingency cover both rooms fully before either one starts.
Ready to Plan a Remodel That Won’t Blow Its Budget?
The surest way to keep a remodel on budget is to decide the expensive things before demolition, not during it. If you’d like to walk through your project with our design team and see the real materials in the showroom before you commit, that’s exactly where a Solstice remodel begins, with a plan detailed enough that the estimate and the final invoice actually resemble each other.
