Why Sealing your Driveway May Help Prevent Costly Cracks Over Time

Not only do driveways store parked vehicles, but they also deal with all kinds of exposure and stress. However, some people do not pay attention to their driveways unless they see cracks beginning to form. At that point, what began as insignificant wear and tear could evolve into something much more costly to fix. This is exactly why seal coating asphalt driveways is considered to be preventive maintenance. If done properly, it can decrease surface damage and slow the rate of degradation.

How cracks begin in the first place

Driveway cracks generally begin small. What looks like a harmless hairline crack could actually let moisture penetrate and cause more serious damage. In the northern states of the US, freezing and thawing processes will aggravate the situation. Moisture penetrates through minute openings in the asphalt, then freezes and gradually enlarges the cracks.


Sunlight is another factor that can affect the asphalt driveway. UV rays can make asphalt susceptible to oxidation over time. The oxidation process leads to brittleness in the surface material, which increases the tendency for cracking. The professionals who deal with asphalt maintenance have identified oxidation and moisture penetration as two leading causes of asphalt deterioration over time.

What driveway sealing actually does

The process of sealing, or sealcoating, involves adding an extra layer to asphalt. In other words, it acts like a protective shield that keeps your driveway safe from water, UV rays, and any chemical spills, such as oil and gas. The sealing process cannot be used to repair significant structural damage, but it could be considered helpful for driveways that are in fairly decent shape.

According to some experts, sealing could be compared to routine maintenance for automobiles. Like oil changes that can prevent the occurrence of engine-related problems, sealing might help reduce deterioration before the damage becomes too serious.

Moreover, the procedure may allow filling in minor cracks on the surface.

Why it may save money over time

Most people are hesitant to undertake sealing because it seems like another financial burden. However, maintenance tends to cost much less than repairing. Minor cracks may be able to receive an early fill. Major cracks, holes, or even issues with the foundation will necessitate resurfacing or total driveway replacement, which is much more costly.

As per industrial recommendations, regular sealing in addition to crack filling may assist in increasing pavement longevity and decreasing maintenance expenses.

This is important for property owners who do not want to incur any surprises. An unattended driveway might also impact the appearance of your home. When thinking about selling, having a smoothly sealed driveway might create a good impression.

Timing matters

Resurfacing is generally not advised by many professionals too frequently or too early. When resurfacing a new driveway, it should be allowed some time to cure before resurfacing. If the driveway already exists, many construction firms advise resurfacing after a number of years, although climatic conditions, weathering effects, and other elements could play a role in determining the resurfacing period.

It becomes obvious that a driveway exhibiting signs such as fading and a dull gray shade may need attention soon. As significant, resurfacing is effective only when the serious problems are taken care of first.

It is not a cure-all

Despite that fact, sealing might be useful to preserve the integrity of an intact pavement, but sealing is not a miracle solution.
It is because sealcoating cannot solve existing problems with cracked asphalt or its deterioration in any other way. This is why specialists recommend using sealcoating as a preventive measure rather than a restoration one. Additionally, property owners should be careful when it comes to sealing in order to avoid mistakes and low-quality services.

A small task that may prevent bigger problems

The work involved in home maintenance usually centers on repairing broken items. However, there are other activities that seek to prevent breakage. One such activity is driveway sealing.

While it might not be as noticeable as interior painting or kitchen remodeling, driveway sealing might be one way to safeguard the surface that gets the most use near your home. Moreover, compared to the expense of fixing damage once cracks have spread out, this preventative measure might be quite worth considering.
