Cost to Paint the Exterior of a House in Kansas City (2025–2026 Pricing Guide)

How to measure the body of a house

We refer to a house's body as its majority. For example, it could be clapboard, stucco, brick, LP SmartSide siding, Hardi Board siding, or beveled cedar. It’s what’s most likely to go through the biggest transformation after being painted and the biggest cost factor in a full exterior paint job.

Our measurement process for houses is very simple. During the measurement, we measure both the length and height of the home. The process is repeated all the way around the house. We adjust for stone or brick that is not being painted. We want to get as close as possible to knowing the number of square feet of the areas that will be painted. A total square footage measurement can be obtained by measuring all four sides of the house.

How to measure the trim of a house

Trim on the exterior of a house refers to the decorative and protective elements that are added to the edges and corners of the structure. It can include items such as window and door trim, corner boards, and eaves and fascia trim. These elements can be made of various materials, such as wood, vinyl, or aluminum, and painted or stained to match or complement the color of the house. The trim helps to define the architectural style of the house and can also provide added protection against weather and pests.

When calculating trim, we try to do our best to simplify things. Typically, trim is painted a contrasting color. We will measure trim that is NOT attached to a window, door, pillar, columns, or vents in lineal feet. This means we are measuring fascia’s, soffit overhangs, rakes, and similar. 

As much as we are trying to achieve accuracy, we also don’t want to nickel and dime our customers by trying to measure out each painted window trim, door trim, window sashes, and air vents. In these instances, we just charge by the actual number. If there’s 6 windows trimmed out in the front, then we will add the quantities up and calculate at 6 each. If there’s 3 entry doors with trimmed-out door casings, then we would calculate as 3 each. 

Window Trim — Most houses have the front window trim painted a trim color to provide some contrast. Only a small percentage of homes have window trim painted all around the entire house. Most homeowners reading this information right now cannot recall if all their window trim is painted or not. When we do the estimating, we base it on what we actually see-UNLESS the owner tells us otherwise.

Miscellaneous — The square footage of the trim is typically increased by the square footage of miscellaneous items such as columns, railings, and porch ceilings. We mentioned that trim gets counted as lineal feet but in our world a lineal foot is the equivalent of a square foot. The linear trim footage would be increased by approximately 24 square feet if you have railings that are 4ft high and 6ft long.

How to count everything else - the 'items'

Every house will have a body and trim to paint but after that things must be customized to the homeowners’ preferences. This is where even though two houses could be the same size and style the following areas can make a significant difference in the final price.

Entry Doors — Some owners want them painted and some have no need because the door just doesn’t require it. Most houses have a front and back entry door while some could have 4 or more.

Window Sashes — It is the sashes that you open and close that are the actual windows (not the trim or storm windows). It's just a matter of counting them up and charging for each one to be painted. In some cases, windows have grids (called mullions), which make painting them more challenging. 

Shutters — Many people do not have shutters on their windows. Some houses may only have 4 while others may have 24. Obviously, the more shutters you want painted the higher the final price. 

Gutters & Downspouts — The cost of gutters and downspouts is generally lumped together, regardless of whether they are painted. It’s easier for the crews to go ahead and paint, plus they will look new. If they don’t get painted, then it requires extensive masking and/or labor to be extra cautious not to get fresh paint on them.

Garage Doors — Some owners want them painted, while others don’t care for it. We’ve come across instances where a house had 6 garage doors. Obviously, the more that get painted the higher the final price.

Foundations — If a house's foundation has already been painted, you may as well paint it again. Unless you have high foundation walls (like more than 2 feet high), we just do a lump sum and don’t worry about measuring them out.

Supplies — We consider supplies such as masking tape, masking plastic, masking paper, shields, tarps, garbage bags, and primers. There is good adhesive orange tape and standard yellow tape. There’s good masking plastic and there’s cheap masking plastic. Over the years, we've learned that buying cheap things doesn't pay off. For that reason, we don’t skimp on supplies.

Caulking — Painting the exterior requires caulking, which is one of the most critical parts of the process. Skim on the quality of the caulk and it will eventually cause problems. We use the 2nd best residential caulk that Sherwin Williams makes. Caulking is used to keep water/moisture out and makes things aesthetically pleasing to the eye.
