How Much Deposit Should You Pay a Contractor? A Builder’s Guide to Paying Safely

It’s one of the most common questions homeowners ask: “The contractor wants money up front. How much is normal, and how do I know I’m not about to get burned?”

It’s a fair question. The deposit is usually the first real money that changes hands, and it’s the moment you have the most leverage and the least information. Here’s how I’d look at it after 30-plus years on the builder’s side of the table.

What a deposit is actually for

A legitimate deposit does two jobs. It secures your spot in the contractor’s schedule, and it covers costs they have to carry before they can start: ordering materials, special-order items like windows or cabinets, permit fees, and mobilizing the crew.

What a deposit is not for: paying for work that hasn’t been done, or funding the contractor’s last job. If the money up front is much bigger than what they need to get your job started, ask why.

So how much is reasonable?

There is no single right number, and anyone who gives you one without asking about your job is guessing. What drives it:

• Size of the job. On a big renovation, a modest percentage already covers mobilization. On a small job, a flat amount may make more sense.
• Special-order materials. Custom windows, cabinets, or engineered items often need to be paid for when ordered, and they can’t be returned. A larger deposit tied to those items is normal.
• Local law. Some places cap deposits for home improvement work. California is the one people usually hear about: the deposit is limited to 10% of the contract price or $1,000, whichever is less (swimming pools have their own rule). Many other places set no cap at all. Check yours before you sign.

From where I sit, the better question isn’t “what percent?” It’s “what is this money paying for?” A contractor should be able to answer that in one sentence. “It covers the cabinet order and the permit” is a good answer. “That’s just how we do it” is not.

Red flags around deposits

None of these prove someone is dishonest, but each one deserves a pause:

• They want most or all of the money before any work starts.
• They want cash only, or payment to a personal account that doesn’t match the company name.
• The deposit amount isn’t written in the contract.
• They pressure you to pay today to “lock in the price” or “hold the spot.”
• They can’t tell you what the deposit covers.
• You can’t confirm their business registration or licensing (where your area requires it) or their insurance.

If you get two or three of these at once, walk away. A good contractor with a full schedule doesn’t need to pressure anyone.

How to protect yourself before you pay

1. Get it in writing first. No money before a signed contract that spells out the scope, the price, the deposit amount, and the payment schedule. If the scope is vague, the deposit is a bet on a guess. Our contractor quote review guide walks through what a solid quote should include.

2. Tie the deposit to something specific. Ask the contract to state what the deposit covers. If it’s for special-order items, it’s fair to ask for the order confirmation or supplier invoice once it’s placed.

3. Pay traceably. Cheque, bank transfer, or card to the company name on the contract. Get a receipt. Avoid large cash payments.

4. Check the basics. Business registration, licensing where your area requires it, liability insurance, and workers’ compensation coverage where that applies. Ask for proof, then check it yourself with the issuing body. It takes an hour and it’s worth it.

5. Keep a paper trail from day one. Every payment, every change, every receipt, in one place. It sounds fussy until you need it. A simple tracker like the Renovation Money Tracker makes this easy to keep up.

Payments after the deposit

The deposit is only the first payment. After that, the healthiest arrangement is a payment schedule tied to finished stages of work, not to dates on a calendar.

Here’s an illustrative example (not a recommendation for your job) of how a mid-size bathroom renovation might be structured:

• Deposit on signing, tied to the vanity, tile, and fixture orders.
• Payment when demolition and rough-in plumbing and electrical are complete and have passed inspection.
• Payment when drywall, tile, and fixtures are installed.
• Final payment after the walkthrough, when the deficiency list is done.

The principle: your payments should roughly track the value of the work in place. If you’ve paid for 70% and the job is 30% done, you’ve lost your leverage, and that’s where most homeowner horror stories start.

Some places also require or allow a holdback, a percentage kept back from each payment until after completion. In BC, for example, the Builders Lien Act sets a 10% holdback. Our article on final payments, holdback, and deficiencies covers how that works at the end of a job.

What if the contractor asks for more?

Sometimes a bigger deposit is legitimate. The most common case is a large special-order item that has to be paid in full when ordered. The fix isn’t to refuse. It’s to structure it:

• Pay for that item separately, against the supplier invoice.
• Ask whether you can pay the supplier directly, or have the item delivered to your property.
• Keep the general deposit small and separate.

A reasonable contractor will usually work with you on this. If they won’t explain it or won’t put it in writing, that tells you something.

What if things go wrong after you’ve paid?

Keep it calm and keep it in writing. Email the contractor with what was agreed, what was paid, and what hasn’t happened. Give a reasonable date to respond. Most disputes come from misunderstandings, and a clear, written summary resolves a lot of them.

If that doesn’t work, your options depend on where you live: consumer protection offices, licensing bodies, small claims court, or a lawyer. The paper trail you kept in step 5 is what makes any of those options workable.

Your quick checklist before paying a deposit

• Signed contract with scope, price, deposit, and payment schedule
• Written note of what the deposit covers
• Business, licensing (where required), and insurance checked
• Paying traceably, to the company name
• Receipt in hand and a place to track every payment
