WHAT TO EXPECT BEFORE WE START

Paint Colors & Timing

Please finalize all paint colors 3–5 days before your start date. This gives us time to order materials, confirm finishes, and ensure your project begins smoothly.
Still deciding? We’re happy to help review samples or guide you toward trending, timeless options.

Preferred Paint Brands

We primarily use Sherwin-Williams because of their reliability, durability, and long-term performance in Missouri weather.
If you have a different brand in mind, just let us know — we’re always happy to review products with you

Color Selection Support

Sherwin-Williams provides complimentary color consultation with trained experts who can help you choose palettes that match your style and home lighting.
We recommend using actual paint samples on your walls rather than peel-and-stick samples — true paint behaves differently on real surfaces and under your lighting conditions.

Purchasing Paint

You don’t need to buy paint yourself.
We select the correct products, confirm finishes, and purchase materials at contractor pricing to ensure accuracy and quality.
If you prefer to purchase your own paint, just let us know — we’ll verify all details ahead of time.

  • Walls: Matte or Eggshell

  • Trim & Doors: Satin or Semi-Gloss

We’ll always confirm finishes with you so everything aligns with your style and durability expectations.

Preparing Your Home

Before we begin, please:

  • Remove small personal items

  • Clear countertops and shelves

  • Move furniture 3–4 feet from walls (if possible)

We handle:

  • Floor and furniture protection

  • Masking and prep work

  • Daily cleanup

  • A full final walkthrough when we’re finished

Window Blinds & Hardware

Please remove blinds before the project begins.
Mounting brackets can stay unless you’d prefer they be removed.

Access to the Home

You do not need to be home during the project.
We can use a key, lockbox, garage code, or scheduled entry — whatever you’re most comfortable with.
We’ll confirm access details before we begin.

Work Hours

Our standard hours are Monday–Friday, 8:00 AM to 4:30 PM.
We work respectfully and maintain a clean, safe environment throughout your project. 

Pets & Children

Please keep pets and children away from active work areas for safety.
We use low-odor, low-VOC products suitable for families and those with sensitivities — feel free to let us know of any special considerations.
