Time to Paint?
Re-painting the exterior of your house can be one of the most the most value-adding (and potentially one of the most costly) improvements you can make to what is likely the biggest investment of your life.
Whether you take on the project yourself or hire a professional painting contractor, the process can be expensive and labor-intensive.
Perhaps the first question most homeowners will ask themselves is, “how do I really know it’s time to repaint my house?”. Knowing whether or not to paint your exterior this year (and whether or not that decision will cost you much more in the future if you don’t) is perhaps the most crucial, and certainly the first, determination to make. So it’s helpful to know the most common and important clues that signal that it’s time to repaint your home’s exterior.
First, it’s important to note that the longevity of any surface coating is affected by a variety of factors: weather, geographic placement of your home (i.e., homes on a hill are more susceptible to weather than those nestled in a valley and surrounded by other structures), surface preparation and products used the last time it was painted, and regular upkeep of the surfaces. A general rule of thumb is that exterior surfaces should be repainted every 7 to 8 years to best maintain the integrity of the underlying substrate.
Below are the most common & important indications that now would be a good time to repaint the exterior of your home:
1) Caulk Failure – Separation of the caulking from the adjoining surface allows water to quietly penetrate underneath and is the most common cause of damage to the underlying substrate which often necessitate expensive repairs. If the rest of your home is in great shape but you see caulk failure slowly becoming visible, you can extend the life of the coating by caulking these areas yourself. If you see a general failure of the caulk all around the house this should act as a glaring notice that it’s time to repaint.
2) Paint Failure – Flaking or peeling paint, like failing caulk, exposes surfaces to humidity and the elements. The primary purpose of paint is for protection from the weather. When a coating fails this opens the door to the great equalizer: water. Exposed and untreated surfaces will tend to deteriorate at a rate at least 11 times faster than a coated surface. More than two square feet of failing paint is an important indication that it’s time to repaint.
3) Chalking – Chalking is the formation of a visible chalk-like residue on exterior surfaces. This behavior is attributed to the loosening of unbound pigment on the surface of a paint as it weathers. It’s tendency to occur is most related most to the nature and amount of pigment in the paint. Darker colors are more affected than lighter ones. In addition to the fact that chalking is an indication that the paint is losing its integrity, this coating failure can cause “chalk run-down” wherein the whitish residue can run down onto to other surfaces which is unsightly and difficult to remove.
4) Wood Rot – This is perhaps one of the most visible (but curiously one of the most neglected) signs of surface failure. Often wood rot will be visible in one or two places around a home’s exterior. Beware of the complacent belief that this is a task that can wait. Wood rot is almost always accompanied by some damage to other, less visible, parts of the exterior. Most likely all the wood in the home was installed at around the same time. Logic would dictate that all the surfaces are aging at a similar rate.
While there are other clues that your home is asking for a new coat of paint (fading, tannin bleed, surfactant leaching, alkali burn, etc.) the above are by far the most common and most worthy of your attention. If you home exhibits one or more of these vital clues, it is recommended that you hire a professional painting contractor to help you remedy the issues and protect not only your home’s exterior surfaces but protect the value of your most valuable asset.
