If you’ve ever searched “How much does interior painting cost?” you’ve probably seen answers like:
$500 – $50,000+
That’s… not very helpful, is it?
The truth is, every home in Beaverton and Portland is different. Ceiling heights vary. Trim packages vary. Some homes have simple square rooms, others have vaulted ceilings, built-ins, wainscoting, and detailed millwork. That’s why at Sisu Painting, we don’t guess.
We measure.
How Sisu Painting Calculates Interior Painting Costs
When we create an estimate, we use professional estimating software that calculates pricing based on detailed “take-offs” — meaning we physically measure and count everything:
-
Square footage of walls
-
Square footage of ceilings
-
Linear feet of baseboards
-
Number of doors
-
Door frames and casing
-
Window casing
-
Built-ins, cabinets, stair railings, and more
This ensures you’re paying for exactly what your home requires — not an inflated guess.
What Does It Cost to Paint a 10×10 Room?
Let’s break down a common example.
Room Example:
-
10′ x 10′ room
-
8-foot ceilings
Walls
A 10×10 room with 8-foot ceilings has approximately 320 square feet of wall space.
At roughly $2 per square foot, that comes to:
$640 for walls
Ceiling
Ceilings in a room this size typically run around:
$200
Baseboards
If the room has 40 linear feet of baseboard and the price averages around $5 per linear foot:
40 LF × $5 = $200
Door + Casing
$200
Window Casing
$150
Total to Paint the Entire Room:
$1,390
Yes — it adds up quickly. Quality materials, proper prep, skilled labor, and insurance all factor into professional painting.
Good News: Our Winter Special Is 25% Off 🎉

What About Kitchen Cabinets?
Kitchen cabinets are one of the biggest transformations you can make — and one of the most detailed.
Most kitchens fall between:
$7,500 – $10,000
Very small kitchens may be less. Large or highly detailed kitchens may exceed that range.
Why?
Cabinet painting is not wall painting. It requires:
-
Degreasing and deep cleaning
-
Sanding and surface prep
-
Priming
-
Fine-finish spraying
-
Dry time and curing
-
Reassembly and hardware reinstall
The skill required to achieve a factory-like finish is significant — but the transformation is dramatic.
Stair Railings: A Hidden Budget Buster
$5,000 – $10,000+
Especially if:
-
You choose a two-tone finish
-
There are many balusters/spindles
-
There’s significant prep needed
They’re labor-intensive and require precision — but they completely modernize a home.
What’s the Average Interior Painting Project Cost?
In the Beaverton and Portland area:
-
Average partial interior project: Around $8,000
-
Whole-house interior (walls, ceilings, trim): Around $20,000
Many homeowners choose to paint in phases — starting with main living areas and updating bedrooms or trim later.
Where You Get the Biggest Bang for Your Buck
If you’re watching your budget:
-
Walls and ceilings give the most dramatic change for the least cost.
-
Trim and cabinetry elevate a space and give a high-end look.
-
Two-tone details add personality but increase labor costs.
We’re always happy to help prioritize based on your goals.
