How to write a price increase letter to your contractor clients

Most contractors haven't raised their rates in over a year. The discomfort of writing a price increase letter to existing clients is usually why — it feels risky, and there's no clean script for it. But if construction input costs rose roughly 7 percent this year while your billing rates held flat, you've been quietly absorbing that gap out of margin. This guide covers how to write that letter: what to include, how much notice to give your contractor clients, and a word-for-word template you can adapt and send this week.

Why 2026 is the year to stop absorbing the squeeze

Construction input costs — the materials, fuel, and equipment your business depends on — climbed steeply in 2026. The Associated General Contractors of America (AGC), which compiles monthly data from the U.S. Bureau of Labor Statistics Producer Price Index, reports that construction input prices rose approximately 7 percent year-over-year through mid-2026. Meanwhile, the prices contractors actually billed clients rose only about 3.6 percent over the same period.

That 3.4-point gap doesn't disappear. It comes directly out of your margin — and it compounds with every month you don't adjust your rates.

If your rates haven't moved in 12 months, you paid that gap yourself. A written price increase notice to your client list is the step that closes it — cleanly, without a confrontation.

Sending the letter in October or early November positions your increase to take effect January 1, which is the natural reset point most clients expect. Starting 2027 at new rates is far simpler than introducing a mid-year change, which always needs more explanation.

How much notice to give contractor clients

Thirty to sixty days is the right window for most residential service work. Here's how to use that range:

30 days minimum for any existing client relationship. Less than that feels rushed and signals a lack of planning. Clients who've called you for seasonal maintenance, referred neighbors your way, or set up recurring work need time to decide whether to book something before your new rate kicks in.

60 days for clients on annual service contracts. If you sell HVAC maintenance plans, plumbing service plans, or any multi-visit arrangement with a locked rate, check the contract terms before sending your letter. Most contracts lock in the rate for the agreed term. Your price increase applies at renewal, not mid-contract — and your letter should say so explicitly: "This new rate applies to any work or renewals beginning January 1, 2027."

No notice for new clients. Anyone calling you for the first time next month gets your current rate sheet. Written notice is for people who've worked with you before and who reasonably expect your old pricing to still apply.

A practical rule: the longer the relationship, the more lead time shows respect. Your five-year regular deserves more than two weeks' notice. A client from earlier this year gets standard 30-day notice. That difference costs you nothing and protects the goodwill you've spent years building.

What to include in a contractor price increase letter

Keep the letter short — under 200 words is the target. Contractors who write long letters explaining every cost item tend to sound defensive. Here are the six things every effective rate-increase letter needs:

1. The new rate or percentage increase. Put the number early and in plain language. "My service call fee will increase from $150 to $165" or "I'll be raising my rates by approximately 9 percent" — both work. Don't bury it in paragraph three where clients have to hunt for it.
2. The effective date. "Effective January 1, 2027" is unambiguous. "Early next year" leaves clients guessing whether to book before the change.
3. A single, honest reason. One sentence is enough. Fuel, liability insurance premiums, and materials all went up this year — that's true and verifiable. You don't owe clients a line-item accounting of your operating costs.
4. A note of appreciation. One line acknowledging the relationship. Not effusive, just real: "I've valued working with you" reads much better than corporate-sounding boilerplate. This keeps the tone human.
5. Your contact information. Make it easy to call or email you with questions. Don't assume clients have your number saved — especially if they call you once a year.
6. A forward-looking close. "I look forward to working with you again in 2027" assumes continuity and confidence. That reads better than anything that sounds like you're asking permission to raise your own rates.

What to leave out: apologies, comparisons to what competitors charge, bullet-pointed cost breakdowns, and anything that sounds like you're seeking approval. A price notice isn't a negotiation — it's a notice.

A sample price increase letter you can send this week

Here's a clean template that works as an email, a printed letter, or condensed into a text message for clients who prefer that:

---

Subject: Update to my service rates — effective January 1, 2027

Hi [Client name],

I want to give you plenty of notice that my rates will increase by approximately 9 percent starting January 1, 2027. Fuel, liability insurance, and material costs all rose meaningfully this year, and this adjustment brings my pricing in line with what it actually costs to do the work right.

I've appreciated every call from you, and that doesn't change. My commitment to showing up on time and leaving the job clean carries over into 2027 at the new rate.

If you have any questions or want to schedule something before year-end at today's pricing, feel free to call or text me at [your number]. I look forward to working with you again.

[Your name] [Trade and license number, if applicable]

---

That's under 130 words. It will feel too short to some contractors, but clients don't read these letters for the prose — they read for the number and the date. Give them both, say something genuine, and move on.

If you're sending by email, the subject line above does the work of the opening sentence. If you're sending a printed letter, add a brief header with your name and trade, then go straight into the body.

How to handle a client who pushes back

Some clients will call after your letter and ask if there's anything you can do about the rate. A few will mention they can find someone cheaper. Here's how to handle each:

Don't negotiate in the letter itself. If you send to 25 clients and three want an exception, handle those one-on-one by phone. Email back-and-forth on pricing tends to escalate; a 10-minute call usually doesn't.

Decide in advance which clients you'd keep at the old rate. There are clients worth holding for another year — someone who's called you every winter for a decade, pays on time, and never argues scope. Know who those are before your phone rings, so you're not deciding under pressure when someone asks.

Let the others go without guilt. A client who leaves over a 9 percent increase was never your most profitable customer. Their slot will fill, and the replacement who calls without comparing you to the cheapest bid on every job will be easier to keep. If you're fully booked right now, a modest rate increase combined with even 10 percent attrition usually means more revenue on fewer jobs.

Before you decide on the new number, use the free markup calculator at JobEstimator to find your actual cost floor. Plug in your overhead, billable hours, and income target — the tool shows you the minimum hourly rate that keeps you whole. Set your new rate above that number, then write the letter.

For the verbal scripts that work when a long-term regular calls and asks "why so much all of a sudden?" — the companion post on how to raise your service call rates without losing regulars covers exactly that conversation.

Takeaways

• Construction input costs rose about 7 percent year-over-year in 2026 while contractor billing rates rose only about 3.6 percent, per the AGC's analysis of BLS Producer Price Index data. If your rates held flat, you paid that gap out of margin.
• Give existing clients 30–60 days written notice. Clients on annual service contracts get the longer window, and the rate takes effect at renewal — not mid-contract.
• A strong price increase letter needs just six elements: new rate, effective date, one-line reason, one-line appreciation, contact info, and a forward-looking close. Keep it under 200 words.
• Don't apologize and don't negotiate in the letter. Handle pushback by phone, one client at a time.
• Know in advance which clients you'd keep at the old rate — so you're not making that call while they're on the phone.

Price your 2027 jobs right from day one

Sending the letter is the easy part once you know your new rate is actually the right number. The harder step is making sure your cost floor has been calculated correctly — overhead, billable hours, self-employment tax, truck, and insurance all factored in.

JobEstimator handles that math inside every quote. Starting at $39/mo on the Solo plan, it calculates your cost base, applies your markup, and shows you what each job needs to gross before you've typed the first line. Set your new rate this October, send the letter this week, and your January work is profitable from the first call.
