How to estimate paint jobs, part 3

In my last post I discussed variables in estimating paint jobs. On the surface, it might seem like there are an unlimited number of variables. However, in terms of essentials, the number is rather limited. For example, while rough-sawn cedar and rough-sawn pine are different, repainting such surfaces will not have any significant material or labor differences; a flush steel door and a flush wood door will require essentially the same time and materials to paint.

In other words, if we identify only those variables that impact labor and material requirements we can create a relatively small and manageable list. In my company, we have only two variables for siding—smooth or rough. (As with all surfaces, we also identify the height and level of preparation required.) The type of substrate— pine, cedar, etc.— does not affect the labor or material requirements; the surface texture does.

If we identify those variables that impact labor, materials, or both, and consider only those variables, our list shrinks considerably.

The exact variables a contractor should consider will vary. Residential work differs from commercial, and repaints differ from new construction. Building materials and architectural features differ across the country, and even within a city or subdivision. Consequently, it is necessary for each contractor to identify those variables which impact the work he performs and the extent of that impact.

Let us look at two common variables and how they impact production rates.

The texture of a surface impacts both material use and production rates. For the same surface area, a rough texture will require more material than a smooth surface. When applying paint by brush on a rough surface additional brushing may be required to properly work the paint into “valleys” and “crevasses”. Again, this will slow production. If the surface is adjacent to a surface that is not being painted, or is a different color, production slows further as the painter tries to maintain a straight line on an irregular surface.

The ability (or inability) to reach a surface directly impacts production rates. Surfaces that must be reached with a ladder will require setting up the ladder, climbing up and down the ladder, and then moving the ladder. While working on the ladder the painter’s reach is limited, which can further slow production. This factor must be considered in your estimating.

Both surface texture and access are variables that must be considered in every project. Each will have an impact on your costs.

In my next post I will offer some final thoughts on estimating.
