A legitimate cleaning price increase letter gives you four things you can check: advance notice of 30 to 60 days, a specific reason tied to a real cost, the exact new price or percentage, and the date it starts. When all four are there and the increase is sized to match the reason, you’re looking at an honest adjustment. When the letter says “due to rising costs, effective immediately” and nothing else, you’re looking at a test of whether you’ll notice.
Price increases in commercial cleaning are normal. Wages rise, insurance climbs, supplies cost more, and a company that never adjusts is either losing money or cutting corners on your account. Forget whether an increase is fair in the abstract. What matters is whether this increase, in this letter, is backed by something you can actually verify.
One line in the letter tells you almost everything, and it isn’t the percentage.
What a Real Cleaning Price Increase Letter Contains
A professional increase letter reads like a business document, not a shrug. It contains, at minimum:
- Advance notice, usually 30 to 60 days. A real company gives you time to budget, ask questions, or shop around. An increase that starts next week is a company betting you won’t push back.
- A specific, named reason. Not “rising costs,” but which cost: a wage increase, a jump in insurance premiums, a supply cost, an added scope. The reason should be concrete enough to check.
- The exact new number. A dollar figure or a clear percentage, not a vague “adjustment.” You can’t evaluate what you can’t see.
- An effective date. The day the new price starts, in writing.
- A reference to your contract, if it has an escalator clause. A company operating in good faith points to the clause you already agreed to, rather than acting like the increase came from nowhere.
If a letter has all five, the company is treating you like a partner. If it’s missing three of them, that tells you how the relationship will go.
Most increases trace back to whatever the contract allowed in the first place, which is why our office cleaning services guide spends real time on contract terms before you’ve signed anything.
The Evidence a Justified Increase Points To
The reason in the letter should point to a cost that actually moved, and you can sanity check most of them in a few minutes.
Labor is the big one. Cleaning is a labor business, and wages are the largest single cost in the bill, so a wage increase is the most common honest reason a price goes up. If the local labor market tightened or a wage floor rose, a proportional increase follows. That connection between wages and your price is the whole story of what drives office cleaning cost, and it’s why a labor reason is usually a real one.
Beyond wages, a few costs legitimately move a price:
- Insurance premiums, which rose across the board for service businesses.
- Supplies and paper goods, which track inflation.
- Fuel, if the crew drives a distance to your building.
- Added scope, if you asked for more rooms, more frequency, or a new service.
The test is proportion. A 4 percent wage increase doesn’t justify a 20 percent price jump. If the increase is roughly in line with the cost it names, it’s honest. If the number dwarfs the reason, the reason is a cover story.
Escalator Clauses: When an Increase Is Already in Your Contract
Many commercial cleaning contracts include an escalator: a clause that lets the company raise the price on a schedule, usually once a year, tied to something like the Consumer Price Index or a fixed percentage.
If you signed one, a matching increase is just the contract working as written. Pull out your agreement and read the clause. A fair escalator names its basis (CPI, or a set percentage), applies once a year, and often caps the annual rise so it can’t spike. An increase that matches your clause is one you already agreed to.
If your contract has no escalator clause, a mid contract increase is a different matter. The company can ask, but you don’t have to accept it until the term ends, and a company that treats an optional increase as mandatory is telling you something. Knowing exactly what your agreement says about price is why the fine print matters, and our guide to commercial cleaning contracts walks through the clauses that decide questions like this.
Red Flags of an Opportunistic Increase
Some increases are tests dressed as adjustments. These are the signs the letter is reaching:
- A vague reason. “Rising costs” with nothing named. If they can’t say which cost, there may not be one.
- No notice. An increase effective immediately or within a few days gives you no room to respond, which is the point.
- A jump far bigger than any real cost moved. Wages and inflation move in single digits. A sudden 25 or 30 percent increase with a generic reason isn’t tracking a cost, it’s testing your attention.
- No effective date or no specific number. Vagueness protects the company, not you.
- A mid contract increase with no escalator clause, presented as final rather than as a request.
One red flag can be sloppiness. Three of them together is a pattern, and it’s the same pattern you watch for everywhere else in a cleaning relationship. If this feels familiar, our list of red flags when hiring a janitorial service covers the rest of them.
The Pennsylvania Wage Picture Right Now
If your letter blames a wage increase, here’s the local context to check it against. Pennsylvania’s minimum wage is $7.25 an hour and has been since 2009, so a state minimum wage hike isn’t currently driving anyone’s costs.
That could change. In March 2026 the Pennsylvania House passed House Bill 2189, which would raise the minimum to $11 in 2027, $13 in 2028, and $15 in 2029. As of this writing it’s stalled in the state Senate and is not law, so any increase citing it today is citing a bill, not a rule. Treat a “because of the new minimum wage” letter in Pennsylvania with caution until that bill actually passes.
What is real is market wage pressure. The national median wage for janitors and building cleaners was $17.71 an hour in May 2025, well above the state minimum, because cleaning companies compete for workers on the open market, not at the legal floor. In Northeastern Pennsylvania, a wage driven increase reflects that competition, not the statute. That’s a legitimate reason, as long as the size of the increase matches it.
How to Respond to a Price Increase Letter
You have more room to respond than most buyers use. Work through it in order:
- Ask for the basis in writing. A good company will happily explain the math. Silence or annoyance is its own answer.
- Check it against your contract. If you have an escalator clause, does the increase match it? If you don’t, the increase is a request you can negotiate.
- Compare the size to the reason. A wage or inflation reason should produce a single digit increase, not a double digit one.
- Negotiate the scope, not just the price. If the number is real but the budget is tight, you can adjust frequency or trim a service instead of accepting the full jump. Both levers are yours.

A fair increase survives every one of these checks. If your cleaning company sends a letter that names its reason, sizes the increase to match, and gives you time to absorb it, that’s a company worth keeping. If you’d like a cleaning partner who prices honestly and explains every change, a free walkthrough estimate is where that starts.
Frequently Asked Questions
How much notice should a cleaning company give before raising prices?
A professional company gives 30 to 60 days of written notice before a price increase takes effect. That window lets you budget, ask for the reasoning, and compare other options if you want to. An increase that starts immediately or within a few days is a red flag, because it’s designed to leave you no room to respond.
Is my cleaning company allowed to raise prices mid contract?
Only if your contract allows it. If you signed an agreement with an escalator clause, the company can raise the price on the schedule that clause spells out. If there’s no such clause, a mid contract increase is a request, not a requirement, and you don’t have to accept it until the term ends. Read your contract’s price section before you agree to anything.
What is a reasonable price increase for cleaning services?
A reasonable increase tracks the cost that caused it, which usually means a single digit percentage in a normal year. Wage growth and inflation move in that range, so an increase of a few percent tied to a named reason is normal. A sudden double digit jump with a vague explanation is not tracking a real cost and deserves questions.
What is a CPI escalator in a cleaning contract?
A CPI escalator is a contract clause that lets the company raise your price each year in line with the Consumer Price Index, the standard measure of inflation. It keeps the contract’s value steady over time without renegotiating from scratch. A fair one applies once a year and often caps the maximum annual increase so it can’t spike in a high inflation year.
Why did my cleaning company raise prices?
The most common honest reason is labor, because wages are the biggest part of a cleaning bill and the market for cleaners has tightened. Insurance, supplies, and fuel also rise over time. A legitimate letter names the specific reason and sizes the increase to match it. If the letter only says “rising costs,” ask which cost, because a real reason can always be named.
Should I switch cleaning companies after a price increase?
Not automatically. A fair increase, clearly explained and sized to a real cost, is a sign of a company that plans to stay in business and keep your account staffed. Switching to the lowest new bid often trades a small saving for a drop in quality and the hassle of onboarding a new crew. Switch when the increase is unjustified or the service has slipped, not just because the number went up.
