Guidelines: How Do You Estimate Exterior Paint Job Costs

How do you estimate exterior paint jobs? This question is pivotal for both homeowners planning a painting project and professionals in the painting business. A precise estimation ensures you have a clear budget outline, avoiding unexpected costs.

In this comprehensive guide, we will walk through each step to accurately estimate painting jobs. From calculating the total square footage of your house exterior to considering factors like paint type and painter’s experience.

We’ll also delve into specifics such as assessing accessibility issues that might affect labor costs, estimating materials needed, including paint and masking paper, and accounting for additional services like prep work or detail work near roof lines.

By the end of this post, you’ll be equipped with all the necessary knowledge on how to estimate exterior paint jobs effectively – whether it’s for residential or commercial properties.

1. Calculate the Square Footage

Determine the amount of paint required by beginning with a calculation. Whip out your tape measure or laser distance measurer and get ready to measure like a pro.

Measure the height and width of each wall, multiply ’em together, and voila. You’ve got the square footage. Don’t forget those fancy features like bay windows and dormers – they count too. If math isn’t your thing, you can always use a handy-dandy online tool like’s Area Calculator to help you out.

  • Measure Each Wall: From ground to roofline and from corner to corner. Get those numbers.
  • Add Architectural Features: Doors, windows, and anything else that’s getting a fresh coat of paint.
  • Deduct Non-Paintable Areas: Subtract the square footage for things like big ol’ windows or fancy stonework.

Psst… If you’ve got a multi-story home, brace yourself for some extra time and complexity. Those high levels can impact the overall cost, so keep that in mind.

Total Exterior Square Footage Calculation Example:

Just so you know, one gallon of paint covers around 350-400 square feet with one coat. Check the label on the paint can for the manufacturer’s recommendation.

Tips for Accurate Measurements:

  1. Avoid guessing – use a proper measuring tool. No eyeballing allowed.
  2. Snap some pics of your property to help you remember what’s what.
  3. For precise estimates, consider consulting professionals like Flora Brothers Painting. They’ve got the skills to pay the bills.

2. Consider the Number of Coats

When estimating costs for an exterior paint job, don’t forget to factor in the number of coats needed. It’s like counting the layers of frosting on a cake – the more, the merrier.

Type of Paint Matters

Choosing high-quality paint is like having a superhero on your side. It covers better with fewer coats, saving you time and money. Check out Sherwin-Williams’ Duration Exterior Acrylic Latex – it’s like a paint ninja.

Color Change Challenge

If you’re going from dark blue to light beige, you might need extra coats to make the transformation complete. It’s like giving your walls a makeover – they deserve to shine.

Surface Condition Matters

Rough or damaged surfaces are like sponges, thirsty for paint. They’ll soak it up, so you’ll need more coats for a smooth finish. It’s like giving your walls a spa treatment – they’ll thank you.

Before diving into the whole project, do a small test patch. It’s like a dress rehearsal for your paint job. You’ll know exactly what you’re getting into.

Remember, multiple coats may cost more upfront, but they’ll make your paint job last longer. It’s like investing in a long-lasting relationship with your home’s exterior.

So, make an informed decision about the number of coats you need. It’s like being the boss of your paint project – you’ve got this.

3. Assess Accessibility

In the world of exterior painting, accessibility is a big deal. Reaching those areas may prove difficult depending on the height and complexity of your house’s exterior.

If your house has multiple stories or tricky roof lines, it can be a pain in the paint job. It means more time and equipment to reach those high spots safely. And that means more money.

Obstacles like trees and shrubs can also make things harder for painters. They have to work around them, necessitating additional time and effort. And if you have fancy trimmings or moldings, well, that’s a whole other level of detail work.

  • Scaffolding: If your home is tall, you’ll need scaffolding. It’s like a paint job elevator, but it costs extra.
  • Ladders: Ladders are the go-to for reaching high spots on shorter homes. Just watch out for wobbly ground.
  • Trees & Shrubs: Greenery can be a pain in the paint. It gets in the way and slows things down.
  • Moldings & Trimmings: These fancy details require extra care. That means more time spent taping and masking.

Be upfront with your client about these challenges. They need to understand why it might cost more to paint their hard-to-reach spots.

4. Estimate Materials Needed

When estimating an exterior paint job, accurately calculate the materials you’ll need. This includes paint, primer, caulk, tape, and drop cloths.

Calculate Paint Quantity

Determine how much paint you’ll need. One gallon covers about 350-400 square feet with one coat. But it can vary based on surface type, texture, or paint color.

Incorporate Primer into Estimate

Use primer for better coverage and longevity, especially when painting over dark colors or raw surfaces.

Caulk and Tape Costs

Seal gaps with caulk and use painter’s tape for clean lines. Both are essential for a professional finish.

The Importance of Drop Cloths

Protect floors, furniture, and landscaping from spills or splatter. Don’t forget to include drop cloths in your material costs.

Tips for Accurate Estimation

  • Avoid underestimating: Round up quantities to have enough materials.
  • Purchase quality products: Invest in high-quality paints for durability.
  • Budget wisely: Cutting corners on materials may cost more in the long run.

5. Factor in Labor Costs

When estimating an exterior painting job, don’t forget about the labor costs. It’s not just about slapping on some paint – there’s prep work and cleanup too.

Professional painters typically charge between $20-$50 per hour, depending on their experience and where you live. So, if you have a 2000 square foot house exterior that takes around 80 hours to paint (including prep work), you could be looking at labor costs of $1600-$4000.

The painter’s experience matters. Although they may seem more expensive initially, hiring experienced painters can be a smart move in the long run as it will get done faster and with fewer mistakes.

  • Preparation: Clean surfaces, scrape off old paint, fill holes, and use masking paper to protect windows and doors.
  • Painting: Apply multiple coats of paint as needed, keeping in mind that different types of paint cover differently.
  • Cleanup: Leave no mess behind – clean up all tools and make sure everything is spick and span.

When calculating labor costs for your exterior painting project, don’t forget to include these tasks. Flora Brothers Painting, a family-owned business, knows all about these details and provides accurate estimates for both residential and commercial projects.

Remember to factor in overhead costs like insurance coverage too. It’s all part of what professional painters charge, along with materials and direct labor expenses.

6. Account for Additional Services

Don’t forget about the extras. Before you start slapping on paint, consider any additional services that might be needed. Power washing and sanding are often necessary to prep the surface for a fresh coat.

Power Washing:

If your abode’s exterior is begrimed with dirt and filth, a power wash is essential. This will ensure that the new paint sticks properly and your house looks spick and span. The expense of a power wash will be contingent on the size and state of your home.


Peeling or chipping paint? Time to break out the sandpaper. Sanding creates a smooth surface for the new paint to adhere to, resulting in a flawless finish. The cost will vary based on the area that needs sanding and the equipment used.

Don’t forget about other tasks like minor repairs or replacing rotten wood boards. These should all be factored into your estimate.

Evaluating Your Needs

Before beginning the painting process, take a detailed look at your home’s exterior to identify any parts that require extra care. From siding to window trims, note any areas that need special attention. A thorough assessment will ensure a job well done.

Hiring Professionals

If you’re unsure about the necessary pre-painting procedures, it’s wise to hire professionals like us at Flora Brothers Painting. With years of experience in residential and commercial painting, we’ll make sure no step gets overlooked. Exceptional results are guaranteed.

7. Finalize Your Estimate

The last step in estimating an exterior paint job is to review all the factors you’ve considered and adjust your estimate accordingly. Don’t forget to carry one.

Once you have taken into account the size of the property and how many coats are needed, review your estimate to ensure accuracy. If it’s a big ol’ mansion, you might need more paint than you think. Don’t overlook those areas that are tricky to get at.

Oh, and if there’s a bunch of old paint that needs removing or areas that need some serious TLC before painting can even begin, that’s gonna cost you extra. Prep work ain’t no joke.

Now, pay attention to these tips to make sure your estimate is on point:

  • Measure twice, paint once: Double-check those measurements, including the trimmings and doors. We don’t want any paint shortages.
  • Inspect like a pro: Look out for any signs of peeling or flaking paint. That’s a red flag for extra prep work.
  • Expect the unexpected: Factor in some extra time and money for those surprise delays. Mother Nature loves to mess with our painting plans.

Your finalized estimate should be as accurate as a bullseye paint job. It’ll show the customers exactly what they’re getting into with Flora Brothers Painting. No surprises here.
