If you’ve been wondering, “How much does it actually cost to paint the inside of my house?” — you’re not alone.
Homeowners from Weiser to Ontario to Fruitland ask us this all the time.

And the honest answer?

Most interior paint projects fall between $7,500–$11,500 for a whole home
and
$600–$750 for individual rooms.

But here’s the thing:
Every home is different. Every project has its own personality. And every family has its own needs.

That’s why NWSP offers no-cost, no-obligation estimates — because painting your home interior isn’t one-size-fits-all. It’s a custom transformation.

Before we get deeper, here’s what really impacts the cost.

The Real Factors That Affect Your Interior Painting Cost

A medium-depth breakdown (without drowning you in contractor jargon):

1. Wall Condition

Cracks, dents, holes, previous DIY texture jobs… you name it, we’ve seen it.
Fixing these isn’t optional — it’s the foundation of a professional finish.

2. Vaulted Ceilings

Beautiful? Yes.
Easy to paint? Absolutely not.
They require specialty equipment and added prep.

3. Color Changes

Going from beige to white? One coat.
Going from dark brown to Swiss Coffee? Three coats (sometimes four).
This directly affects labor time and overall cost.

4. Number of Rooms & Total Square Footage

More rooms = more cutting in, more prep, and more labor hours.

5. Premium Products

We only use contractor-tier premium paints — the kind that last longer and look better…
and thanks to contractor pricing, we pass the savings on to you.
Often our premium product pricing ends up close to what homeowners pay for mid-grade paint at the hardware store.

Why DIY Usually Isn’t Cheaper (Even When It Seems Like It Is)

We love a good DIY project…
but painting an entire home interior isn’t usually one of them.

Homeowners often overlook:

• Cost of tools

• Drop cloths

• Tape

• Caulk

• Rollers

• Brushes

• Sanding equipment

• Primer

• Fixing mistakes

• Buying more paint because the first sheen/brand didn’t cover properly

• Lost evenings and weekends

• Living in a space that smells like paint for days

• Clean up

• Unexpected texture mismatches

When you add it all up?

Most homeowners spend more time, more stress, and nearly the same dollars as hiring a professional… without the warranty or the flawless finish.

Which brings us to:

Most homeowners just want the job done right — quickly — and without the stress.

That’s exactly what we do.
