Multiple estimates are very welcome!
What is the exterior wall cover method?
We will explain in detail the recommended points and precautions of the exterior wall cover method!
The exterior wall cover method is a construction method that overlays a new exterior wall on top of the existing one.
It can be applied to various types of exterior walls, including ALC walls, ceramic siding, and mortar walls.
The exterior materials used in the exterior wall cover method are generally lightweight and durable metal siding.
Although the costs are higher compared to exterior wall painting, it is a method of exterior renovation that has various benefits and is gaining attention year by year.
Why is the exterior wall cover method so popular?
Here are the “five points” that have made Kakeru Koumuten’s exterior wall cover method well-received!
Point 1 Super high durability!!
Metal siding offers an overwhelmingly high expected durability compared to exterior painting.
Made of Galvalume steel, SGL steel, and aluminum, there are various types of metal siding, but with aluminum, you can expect a durability of over 40 years!
Additionally, unlike ceramic siding or mortar exteriors, it does not crack or break, which is one of its strengths!
If you use high-durability sealing materials, maintenance will be unnecessary for nearly 30 years!
Point 2 Improved Insulation!!\\\\@^
Cross-section of metal siding
The metal siding used in the exterior cover method has integrated insulation material.
Moreover, by installing battens before the metal siding installation to create a ventilation layer, insulation performance is significantly improved!
This improvement in insulation is one of the major benefits of metal siding.
Point 3 Comprehensive Warranty for Peace of Mind!!
While many construction companies offer their own warranties for exterior painting, manufacturer warranties are generally not included.
Metal siding comes with solid manufacturer warranties such as coating and perforation guarantees, making it a reassuring choice for long-term exterior renovations!
Point 4 Improved Waterproofing!!
With the exterior material being double-layered, it prevents rainwater intrusion, significantly enhancing waterproofing.
Applying waterproof paper before installation further increases waterproofing performance!
Point 5 Improved Aesthetics!!
Various designs such as wood grain and tile patterns
Metal siding allows for a finish that resembles new construction, which cannot be achieved with exterior painting.
There are various designs available, ranging from simple styles to tile and wood grain patterns.
You can choose from a variety of designs to match the atmosphere of your building and your preferences!
Major manufacturers include “Aiji Industry“, “Keimyuu“, “Nichiwa“, and “Asahi Tostem“, each offering a wide range of types and designs of metal siding.
If you find a product you are interested in from the catalog, you can also request cut samples!
What to be aware of when doing exterior wall cover work with metal siding?
Next, we will explain the “three points to be cautious about” when using metal siding for exterior wall cover work!
Caution 1 Few contractors can perform the work
There are significantly fewer contractors capable of performing the cover method with metal siding compared to exterior painting contractors.
Many inexperienced contractors exist, which can lead to frequent troubles.
Since there is often a variation in estimated costs, to ensure a satisfactory construction, if you are considering the exterior wall cover method with metal siding, make sure to get estimates from three or more companies and carefully review the details!
Caution 2 Prone to dents and scratches
Metal siding can develop dents from impacts when objects hit it.
Additionally, being prone to scratches is one of its disadvantages.
If noticeable scratches occur and are a concern, you can request repairs from a specialized repair contractor!
Caution 3 Long construction period
Exterior wall cover work is arguably the most extensive type of exterior renovation.
While exterior painting typically takes about two to three weeks, exterior wall cover work can often take close to a month.
The long construction period can be a source of stress for residents, making it one of the disadvantages.

About the Costs of Exterior Wall Covering Work
This is a guideline table for the estimated costs of exterior wall cover work.
It serves as an estimate for the cost of performing the exterior wall cover method on a building with a floor area of 30 tsubo.
The cost of exterior wall cover work is determined by the following calculation.
Exterior wall area (㎡) × Siding unit price + Equipment removal and installation cost + Additional painting cost = Total amount
This will be the total.
| Material | Expected Durability (Years) | Cost Assuming a building area of 30 tsubo (150㎡) |
| Galvalume Steel | 30 to 35 years | Including Tax Approximately 2,000,000 yen (Siding unit price 11,000 yen/㎡~) |
| SGL Steel | 35 to 40 years | Including Tax Approximately 2,200,000 yen (Siding unit price 12,500 yen/㎡~) |
| Aluminum | 40 years or more | Including Tax Approximately 2,500,000 yen (Siding unit price 14,000 yen/㎡~) |
The amount will vary depending on the number of painted accessories and windows, as well as the equipment that needs to be removed and reattached.

How to Choose a Siding Contractor
There are fewer contractors that handle exterior wall cover work compared to exterior painting contractors, so it may be challenging to find a reputable contractor, such as “where should I request?”
The most important thing when choosing a contractor or obtaining a quote is to always obtain multiple quotes!
Therefore, when requesting exterior wall cover work, let’s check the following four points.
1. Check the contents and materials of the estimate
2. Confirm the presence of warranties and aftercare services
3. Obtain multiple quotes from several contractors (at least three companies)
4. Verify if the contractor performs the exterior wall cover work in-house
By confirming the above four points, you will be able to choose a reliable contractor.
1. Check the contents and materials of the estimate
When obtaining an estimate for exterior wall cover work, let’s check the following items!
・Is the proposed new siding material suitable for your needs?
Make sure that materials that meet your requirements, such as durability and insulation, are being proposed!
Since there are various types of metal siding, such as cost-effective siding and insulation-focused siding, confirm whether the proposed siding meets your original requirements!
・Is it proposed with the appropriate construction method?
When performing exterior wall cover work, it is necessary to create a ventilation layer between the existing exterior wall and the new exterior wall material using a method called “ventilation method“.
If you apply it directly without creating a ventilation layer, moisture cannot escape, leading to mold or corrosion, and may cause peeling or lifting of the exterior wall material.
Check whether the proposed work is appropriate!
・Are the quantities and construction details described in detail?
If the content is vague, such as “exterior wall cover work 1 set,” it will be difficult to understand the construction method and what the costs are for, making it hard to compare estimates.
Having clear unit prices and quantities for items like foundation water cut and edge lengths will provide peace of mind and help prevent issues.
If there are items of concern that are not included in the estimate, confirm the reason for their exclusion!
・Check the auxiliary materials to be used!
Check not only the siding itself but also the types of detailed auxiliary materials such as “types of battens“, “siding fasteners“, and “types of waterproof paper“!
For example, siding fasteners are screws, and the overall cost will vary between iron and stainless steel.
While iron may appear cheaper at first glance, stainless steel is resistant to rust and is the recommended fastener.
2. Confirm the presence of warranties and after-sales maintenance
When choosing a contractor for exterior wall cover work, make sure to check for warranties.
Since exterior wall cover work is one of the more expensive types of exterior renovations, it’s important to confirm not only the manufacturer’s warranty but also whether the contractor offers their own warranty!
If the contractor has a warranty period, they may provide free repairs within that period.
The warranty period varies by contractor and the specifics of the work, but a 5 to 10-year setting is common.
Additionally, some contractors offer after-sales services separate from warranties, so be sure to check if the contractor you are considering has after-sales services.
Kakeru Koumuten Co., Ltd. always includes a warranty with exterior wall cover work.
We also provide after-sales maintenance, sending out annual direct mail, so if you wish, annual inspections can be arranged.
3. Obtain estimates from multiple contractors (at least 3 companies)
When requesting exterior wall cover work, be sure to obtain estimates from multiple contractors.
The costs for the same repair can vary between contractors, as can the warranties and after-sales services offered.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at the best possible price, obtaining estimates from multiple contractors is essential.
When comparing estimates, consider not only the costs but also the details of the plans, materials, and ancillary supplies!
4. Confirm whether the company performs exterior wall cover work in-house
There are differences in costs between companies that handle the work in-house and those that outsource it to external companies, and there is also a higher likelihood of miscommunication and issues arising with external contractors.
Moreover, if problems occur after the work is completed, responses may be delayed, or the company may not have dealings with the external contractor, leading to further complications.
Being able to receive immediate assistance when issues arise is one of the reasons why companies that perform the work in-house are recommended!
