When you start considering exterior wall painting, many people feel the concern, "I don't know which company to choose." Even if you get quotes from multiple companies and compare them, it's often difficult to understand the differences in prices, paints, and construction details, leading to confusion about what criteria to use for selection.
Especially in recent years, with rising paint prices and fluctuating construction costs, the era of "cheap means safe" is over.
This article will clearly explain how to choose without regret, based on the current situation of the exterior wall painting industry seen nationwide.
To ensure that even those considering exterior wall painting for the first time can think thoroughly, we have showrooms in Nagoya City, Owariasahi City, and Toyota City.
Our company will celebrate the 1st anniversary of the Nagoya East store and the 3rd anniversary of the Toyota store in May.
Precisely because we are in an era of soaring prices, we will hold an 【Anniversary Event & Campaign】 in May.
May Event
We hope to give back to the local community through exterior wall painting.

■Why is exterior wall painting difficult to compare?
At first glance, exterior wall painting seems similar across all companies.
- Similar paint names
- Explanation of three coats
- Similar estimates
However, in reality, it is a construction project where there can be significant differences in construction quality and durability.
The reason for this lies in the parts that become invisible after completion.
For example, the processes of substrate treatment and primer application cannot be confirmed in the finished product, but if these processes are insufficient, deterioration can progress within a few years.
In other words, it is difficult to compare precisely because it is a construction project that cannot be judged by appearance.
■Reasons why choosing based solely on price leads to failure
A common mistake in exterior wall painting is to judge solely by price.
Currently, the price of raw materials for paints is on an upward trend nationwide, and movements for price revisions have been particularly noticeable since April 2026.
One of the backgrounds to this is the rise in crude oil prices and transportation costs due to the situation in the Strait of Hormuz.
Many resins and solvents used in paints are petroleum-derived, and are greatly affected by crude oil prices, so this impact is spreading to paint prices.
In fact, we have received communication from a certain manufacturer that there is a possibility of paint price increases without prior notice due to the unstable situation.
(Normally, price increases are notified 2-3 months in advance.)
In such a situation, if prices are forcibly lowered, it is not uncommon for cost adjustments to be made elsewhere.
- Lowering the grade of paint
- Reducing the number of coats
- Simplifying substrate treatment
These aspects are difficult to discern from an estimate, and as a result, lead to regret such as "it deteriorated faster than expected."
It is dangerous to judge solely by the cheapness of the price.
Comparison Point ① How to paint (approach to the process)
In exterior wall painting and roof painting, "why" that process is necessary is more important than "how many times" it is painted.
For example...
In roof painting, deteriorated roofing materials tend to absorb paint easily.
If the primer application is insufficient in that state, the performance of the paint will not be fully demonstrated.
Therefore, depending on the condition, construction tailored to the building, such as applying primer twice, is necessary.
It is important whether the company can explain the "reason" for the process.
Comparison Point ② Paint track record
Not only the type of paint but also its track record is important.
- How much has that paint been used for construction?
- What kind of buildings has it been used on?
- What is its condition after years?
Even with the same high-durability paint, there can be differences in the finish between a company that is accustomed to handling it and one that is not.
Also, not only the construction company but also the 【track record of the paint company】 that manufactures the paint used by that construction company is an important point.

The key is to look not only at the paint name but also at the "experience of the construction company and paint company."
Comparison Point ③ Construction track record (ability to handle house builders)
Equally important as the paint track record is the type of housing for which there is a construction track record.
Exterior wall materials and structures differ for each house manufacturer, and construction methods and precautions also vary greatly.
For example,
- House builder homes (Sekisui House, Daiwa House, Misawa Homes, Toyota Home, etc.)
- Local builder homes
- Traditional construction method homes
Sekisui House
Toyota Home
Daiwa House
Misawa Homes
For each, the specifications of the sealing, the characteristics of the exterior wall materials, and the methods of substrate treatment differ.
If construction is carried out without understanding these differences, it can lead to defects in the paint film and early deterioration.
Especially in recent years, with rising paint prices and fluctuating construction costs, the era of "cheap means safe" is over.
