📅 How Long Is a Contractor Quote Valid? (And What to Do When It Expires)

You get a contractor quote in February. Life gets busy. You come back to it in May wanting to move forward. The contractor says the price has gone up. Can they do that? Almost certainly yes. Here is how quote expiration actually works, what is standard, and how to protect yourself.

The Basics: Most Quotes Are Valid for 30 Days

The most common standard in the contracting industry is a 30-day quote validity. This is not a law, it is a convention, but it is widely followed. Good contractor quotes should state the expiration date explicitly on the document. If yours does not, assume 30 days from the quote date is the window.

Some quotes have shorter or longer validity windows depending on the trade and current market conditions:

Auto repair quotes: 3 to 7 days, sometimes less. Parts prices fluctuate and availability changes quickly. HVAC equipment quotes: 14 to 30 days. Equipment prices, especially during seasonal demand spikes, can change. Roofing quotes: 30 to 60 days in most markets. Material costs are relatively stable short-term. General construction and remodeling: 30 to 90 days depending on project size and material intensity. Larger projects with long material procurement timelines often come with longer validity windows.

Why Quotes Expire

Quotes expire because the inputs that went into them can change. Material costs fluctuate. Labor availability and rates shift. Fuel and delivery costs change. Permitting fees get updated. A contractor who gives you a price in February is committing to deliver that project for that price based on conditions in February. If conditions change, their costs change.

This is not a scam. It is a legitimate business reality. A roofing contractor who quoted you in February at $14,500 may genuinely face higher shingle costs in June. Shingle prices rose significantly in 2021-2023 and have continued to fluctuate. A quote from several months ago may no longer reflect their actual cost to do the job.

When Price Increases Are Legitimate vs Suspicious

Legitimate reasons a quote might increase after expiration: Material cost increases documented by supplier price sheets. Significant time gap, typically more than 60 days. Scope changes you requested or conditions on site that were different than estimated. Seasonal demand changes that affect labor availability.

Suspicious reasons to raise a price: The work is starting this week but the price jumped between signing and starting. No specific reason is given beyond "costs went up." The price increase is a round, large number like "just adding $1,500" without itemization. A contractor who gave you a low quote to win the bid and is now trying to bring it up to what they actually wanted.

The difference: a legitimate price increase comes with specific documentation. A contractor who can show you a supplier invoice showing material costs increased 12% since the quote is being straight with you. One who just says "prices went up" without specifics may be fishing for more margin.

How to Protect Yourself

The most effective protection is a signed contract, not just a quote. A quote is an offer. A signed contract is a commitment. Once you sign a contract with a price, that price is locked. The contractor cannot raise it unilaterally without your agreement (though legitimate change orders for genuinely unforeseen conditions are a normal part of construction).

If you want to move forward with a quote before you're fully ready, ask the contractor to extend the quote validity in writing. Many will extend for 30 days at the same price, especially if you're close to signing. Some may ask for a small deposit to hold the price.

For large projects ($10,000+), negotiate price escalation terms into the contract. Something like: "All prices in this agreement are fixed unless material costs increase more than 10% from the quote date, in which case we will adjust materials pricing with documentation." This protects both parties fairly.

What to Do When a Quote Has Expired and the Price Went Up

First, ask for the new itemized quote. Do not accept a verbal "it'll be $2,000 more." Get the new number in writing with the changes identified.

Second, research whether the claimed cost increases are real. Shingles, lumber, copper, and other building materials have price indexes you can check. If a contractor claims lumber went up 40% but you can verify it went up 8%, you have a basis for negotiation.

Third, get a fresh competing quote. If a contractor's revised price feels high, getting a fresh second opinion tells you whether the market has actually moved or whether this contractor is opportunistically repricing.
