When is the Best Time for Exterior Painting? How to Determine the Optimal Timing?

Hello everyone! Kakeru Koumuten Co., Ltd. is here!

For those considering exterior painting,

“When is the right time to request the work?”

“Is there a suitable season for it?”

Many people have such concerns.

In this article, we will explain in detail the best season for exterior painting and how to determine the best timing for your request.

When is the right time for exterior painting?

Now, let’s take a closer look at the suitable timing for exterior painting.

The best season for exterior painting

It is said that spring and autumn are the best seasons for exterior painting.

Specifically, from March to May and from September to November are the most suitable times.

The reason is that the temperature and humidity are neither too high nor too low, which helps the paint dry faster.

Faster drying of the paint means that the construction period can be shortened.

If the construction period is prolonged, scaffolding will remain around the house for an extended time, which can be inconvenient.

By scheduling your request for spring or autumn, you can avoid such inconveniences and achieve the desired finish.

.

Therefore, there is also the option to intentionally avoid the best season, but if you really want to request during spring or autumn, it is advisable to consult with the contractor as early as possible.

Times to be cautious

Exterior painting can be done without issues outside of spring and autumn.

However, you must be cautious during periods of high humidity and low temperatures.

Specifically,

・Temperature → Below 5 degrees
・Humidity → Above 85%

If these conditions occur, it may not be possible to carry out exterior wall painting depending on the paint used.

This is because working under such conditions can lead to

paint-related

・Paint not drying
・Accelerated deterioration

which could result in various disadvantages.

Explaining the Advantages and Disadvantages of Exterior Wall Painting by Season!

Next, we will explain the advantages and disadvantages of exterior wall painting by season.

Spring

When requesting in spring, the stable climate means that there is less variability in success, and the work is likely to be completed in a short period.

However, as mentioned earlier, it is a busy season, so it may be difficult to make reservations, which is something to be cautious about.

Rainy Season

As spring comes to an end, the rainy season approaches.

If it continues to rain, it may become difficult to proceed with the work, and the construction period may be extended.

Additionally, since it is a season prone to rain, if you do not hire a contractor with both skills and experience, there is a possibility that the results may not meet your expectations.

 

That said, during the rainy season, the number of reservations tends to decrease, and inquiries also tend to drop, making it easier to adjust schedules, and there may be opportunities to negotiate on pricing.

 

Summer

Summer tends to have stable temperatures and humidity, making it a suitable season for painting.

However, during exterior wall painting, you cannot open windows, so you will need to use air conditioning to lower the indoor temperature.

Additionally, there may be sudden rain showers or downpours, which could force you to halt work unexpectedly.

 

Autumn

As explained earlier, autumn is also considered the best season for exterior painting, just like spring.

However, this season tends to see a surge in reservations and inquiries, so it is likely to be difficult to start work immediately after making an inquiry, so please be cautious.

 

Winter

Many people think, “Isn’t winter unsuitable for exterior painting?”

However, this is not necessarily the case.

If the temperature does not drop significantly and humidity can be maintained to some extent, there are cases where work can be done.

During this time, compared to busy seasons, the number of requests and inquiries decreases, so there are contractors who can take on last-minute requests quickly.

 

However, since temperatures drop significantly in winter, there is a possibility that the paint may not dry or may freeze, so be sure to consult with a contractor considering the characteristics of your local area.

 

When is the right timing for exterior painting?

Next, let’s explain in detail the timing for carrying out exterior painting.

When 10 years have passed since building the house

The lifespan of exterior paint is said to be around 10 years.

The reason is that the waterproof performance of the siding boards, which are commonly used in Japanese houses, is likely to decline.

By repainting when 10 years have passed since building the house, you can maintain a beautiful appearance and also reduce damage from UV rays and rain and wind.

 

When fading appears on the exterior

It is also recommended to request painting when fading appears on the exterior.

If the fading is mild, it may only affect the appearance without causing other problems.

However, if that condition is left unattended, it is likely to lead to cracking or damage to the exterior, so it is advisable to consult as soon as possible.

 

When chalking occurs

When you touch the exterior and a white powder-like substance gets on your hands, it is called the chalking phenomenon.

The reason powder gets on your hands is due to:

・UV rays
・Wind
・Rain

These factors cause the paint to peel off.

If this condition is left unattended, it may lead to cracks or mold, so it’s important to take action early.

Timing of Paint Peeling

If the paint is peeling, it is quite possible that the paint film has deteriorated significantly.

If this condition is left unattended, there is a possibility that water may enter the house, and in such cases, not only exterior wall painting but also other construction work will be necessary, leading to significantly increased costs.

Therefore, it is recommended to consult a contractor when the peeling of the paint becomes noticeable.

Timing of Cracks Occurring

In technical terms, this is referred to as a crack, and it is advisable to request repairs when cracks appear on the exterior wall.

To put it another way, cracks indicate that the damage to the exterior wall has progressed considerably, so it is better to address it promptly.

If cracks are left unattended, it may not only lead to water intrusion and mold but also decrease the strength of the house, so caution is advised.

The Important Reason Why “Choosing a Contractor” is More Crucial Than Timing for Exterior Wall Painting

Exterior wall painting is best done in spring or autumn, but it can be carried out in other seasons as well.

When making a request, considering the season is certainly important, but even more critical is choosing the right contractor.

This is because if you hire a reputable contractor, they will explain the advantages and disadvantages of working during that season and proceed with the work with care.

Moreover, even during seasons that are not very suitable for exterior wall painting, skilled craftsmen will carry out the work, improving the quality of the job.

Conclusion

Exterior wall painting can be done year-round, but there are suitable times and some periods when the work may become slightly more challenging.

That said, if you can choose a reputable contractor, they will carry out work suited to the season and will explain the advantages and disadvantages for each period before starting the job.
