How to Bid a Paint Job – A Free Guide to Estimating (in 2026)

January 10th, 2021 | Chandler Zieg | Featured, Painting Business Articles | 206 Comments

We’ve painted houses for 15 years now and still run into situations that are difficult to bid, but over time we’ve developed a simple process that can teach anyone to bid a painting job; exterior or interior.

The 5 big considerations for estimating a paint job are:

  • Paint
  • Materials
  • Labor
  • Marketing
  • Your Mark-up

That’s why we love painting businesses; they’re simple. We’ll break down each of these categories in detail.

1. How Much is Paint?

A gallon of paint can be anywhere from $15-$120. It really depends on the brand, the quality and the contractor discount you’re getting.

A homeowner might be paying $40 for a gallon of paint as a one-off customer, when an experienced painting contractor can get the same gallon for $19 etc. This depends on the relationship the contractor has with the paint store, and how many gallons they’re buying each month.

A personal example: When we first started our painting business, we were paying $44 per gallon of Sherwin Williams “Super Paint”. Over time, we developed a relationship with the store and started buying hundreds of gallons each month. That gave us more negotiation power with our paint distributor, allowing us to get that same gallon down to $23.

From $44 to $23! That was a significant saving for our painting business: That’s 47% off our paint expenditure category.

The cost of paint also depends on the quality. A lower quality paint typically has less resin (the resin is what actually holds the paint together), whereas high quality paint generally has more resin and holds up better over time.

Cost of Paint (Avg. Per Gallon)

Quality: Low Grade Mid Grade High Grade
Homeowner Price $25 $50 $125
Contractor Price $19 $32 $78

How much paint do you actually need?

Size of House House Body Color Trim Color Total Gallons Total Cost (@$32 per gallon)
1500 sq ft. 8 2 10 $320
2500 sq ft. 12 3 15 $480
4000 sq ft. 20 5 25 $800

2. How Much are Other Materials?

These are the most common painting materials you’ll need for a random 2,500 square foot exterior paint job with medium prep work:

-Masking Plastic (2 rolls) $25
-Masking Paper (3 rolls) $19
-Tape (10 rolls) $45
-Caulking (6 tubes) $25
-Primer (1 gallon) $35
Total Cost: $149

How many materials you need also depends heavily upon:

  • Amount of prep-work needed
  • How many windows
  • How much brick
  • How much roof line
  • How much you have to mask off in general

This checklist is pretty typical, but can vary greatly depending on the house.

If there is a LOT of prep needed, you might go through 3 gallons of primer, and 12 tubes of caulking for example,

If there is a LOT of brick + roof line that needs to be masked off, you might go through 5 rolls of paper and 3 rolls of plastic.

3. So How Much is Labor?

This is by far the hardest cost to estimate when bidding a house, mainly because there are many factors.

The short answer is; A good crew of 2-3 painters can finish the exterior of a 2,500 square foot house in 1-2 full days. And a good crew usually costs about $1000 per full work day.

However, the following conditions can as much as triple the time + labor it can take to properly paint a house:

  • Heavy Prep-work (peeling, wood damage, failed caulking)
  • House access (difficult ladder placements, steep roof etc.)
  • Type of windows (embedded windows, vinyl windows)
  • Vegetation coverage (trees in the way, lots of ivy, nice gardens)
  • Radically different colors (applying 2 or 3 coats before the paint covers the old color)

The safest/best way to get a good price on labor is to actually bring your experienced crew to the house with you. They can alert you of certain aspects of the house that are very time-consuming, so you can factor in the extra work in your bid.

A Note If You’re New: If you are inexperienced at painting or estimating, or you run into a situation that you don’t know how to bid, it is better to charge MORE in order to protect your margin of error. Making mistakes at the beginning is inevitable so charging more protects you against an underbid job, which can be especially demoralizing.

Here’s a table to help you with estimating labor cost with a crew of 2-3 painters:

Size of House Full Work Days Total Labor Cost
1500 sq ft. 1 $1,000
2500 sq ft. 1.5 $1,500
4000 sq ft. 3 $2,500

Ok, so that covers your paint, materials and labor..

4. What’s the cost of Advertising Your Painting Business?

You can market your painting business a variety of ways, we have 7 pretty good methods that we use for our own painting businesses here

No matter what you use for marketing, whether it’s lead providers, lawn signs or door-knocking, you should track the overall cost. It’s important to isolate the marketing that gives you the best ROI (return on investment) and spend all your time/money there.

Keeping your marketing percentage below 10% is a good rule-of-thumb. Let’s say you sell a $3,000 paint job. Spending $300 or less on marketing to obtain the job will still leave you plenty of profit margin to continue.

Here are some typical marketing costs for our painting business:

  • Lead Providers – $50-$150 per lead
  • Lawn Signs – $15 per sign
  • Door-to-door leads – $20 per lead
  • Flyer Drops – $2,000-$5,000 per drop
  • Referrals – FREE
  • Chambers/Business Groups Networking – FREE

5. How do you make sure you make a profit?

You’re hopefully in business to provide a quality service and make money in the process. That’s why estimating correctly is so important. How many of you have been stuck on a nightmare job that’s underbid to boot? We’ve certainly had a few of those..

So what do you want your markup to be in the bid? What’s a good profit margin to target as a painting business owner?

Let’s use our 2,500 square foot house as an example:

Paint – $425
Materials – $150
Labor – $1,500
Marketing – $150
Mark-up – ?

Let’s say I’m targeting a 40% profit margin as a sole owner with a couple crews:

If I’m going to spend $2,225 on the main cost categories, I probably want to charge around $4,000 for the whole project as the estimator:

$4,000 Job

-$2,225 Expenses

=$1,775 Profit

6. How to Bid Interior Jobs:

Interior jobs will almost always be more expensive. Sometimes they will be 2 or 3x the price of an exterior job. This is because:

  1. There are more walls (and surface area)
  2. More doors, windows, baseboards (don’t forget about closets)
  3. Usually more than 1 coat is needed to cover (especially for ceilings)
  4. More paint is needed
  5. It is more of a detailed process for masking/cleanup etc. (more labor hours)

Some painters just charge per room; I’ve heard anywhere from $400 to $800 per room – depending on the size of the room obviously. But a safe range to stay in as a painting business owner is:

Exterior Paint Jobs:
1500 sq ft – $2,500-$3,500
3000 sq ft – $4,000-$6,000
5000 sq ft – $6,000-$9,000

Interior Paint Jobs:
1500 sq ft – $2,900-$4,000
3000 sq ft – $6,000-$9,000
5000 sq ft – $10,000-$15,000

Find a method that works best for you and keep it consistent. Always be mindful of your profit margin and bid higher if you’re unsure of a scenario. We hope this helps and simplifies your bidding process!
