PAINTING TRIM

Painting trim can include baseboards, windows, doors and crown molding.  We can also paint the wainscoting and chair rail in your kitchen or bathroom as well as the panel molding in your hallway or foyer.  The trim in your home highlights the color of your walls.

Swell Contractors can you give you a free estimate for painting your trim.  First, we will inspect the rooms where you want your trim to be painted.  Next, we will discuss the factors that we consider when calculating the cost of each room.  To learn more about what cost factors may be considered continue reading below.

A tape measure and the formula of how to measure linear feet of baseboard trim.

Linear Feet/Surface Area

The amount of paint required for painting trim depends on the surface area.  One gallon of paint will cover a surface area of 400 square feet.  

First, we measure a rooms dimension to determine the linear feet of the baseboard molding and crown molding. Next we multiply the total linear feet by the width of the molding to calculate the total surface area.  Window dimensions are measured the same way.

In addition, we count the number of doors to be painted.  We add the calculations of the doors and door frames to the total trim surface area to estimate the amount of paint needed.

Two examples of different types of paint. One oil based paint and one latex paint.

Type Of Paint

Depending on whether the existing paint on all trim is a latex based paint or oil will make a difference in price. Oil based paints and primers contain VOC’s and require the painter to use a ventilator mask to protect from the strong fumes. 

Oil based painting requires more skill. If applied incorrectly, the paint can sag to the floor while it cures over night.  Latex paint will not bond to oil based paint.  The trim must first be primed with an oil based bonding primer.  Only then can the trim be painted in latex paint.

We will wipe the trim with a wet rag soaked in rubbing alcohol to determine what type of paint currently exists..  If the paint does not come off, then the current paint is oil-based.

Common conditions of damaged trim.

Existing Condition

Older homes often have multiple layers of paint on trim. In this situation, it may take more preparation.  First, you must scrape and sand the trim to leave a smoother finish. Then the trim should be dusted before painting.

When there are dogs in the home, there may be a case where the dog has left chew marks on the trim.  In this case, the marks must be patched with wood filler and sanded. 

On the other hand, if new molding has just been installed it will require time to fill all nail holes with puddy and caulk all seams. Raw wood requires primer before painting two additional coats of paint. In addition, changing a dark color trim to white will also take multiple coats to cover.
