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 that overlays a new exterior wall on top of the existing exterior wall.
It is possible to overlay various types of exterior walls such as 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 cost is higher compared to exterior painting, it is a renovation method for exterior walls that has various benefits and is gaining attention year by year.
Why is the exterior wall cover method popular?
We will introduce the “5 points” that have received high praise for Kakeru Koumuten Co., Ltd.’s exterior wall cover method!
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, making its sturdiness one of its advantages!
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 comes with integrated insulation.
Moreover, by installing battens before the metal siding installation to create a ventilation layer, insulation performance is significantly enhanced!
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, providing a high sense of security 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!
Point 5 Enhanced Aesthetic Appeal!!
Various designs such as wood grain and tile patterns
Metal siding allows for a finish that resembles a brand-new construction, which is impossible to achieve with exterior painting.
There are various designs available, ranging from simple styles to tile-like and wood grain patterns.
You can choose from a variety of designs to match the atmosphere of your building and your personal 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 while looking at the catalog, you can also request cut samples!
What are the points to be cautious about when performing 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 methods!
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, leading to a higher occurrence of troubles.
Since there can often be a wide range in estimate 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 drawbacks.
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 2 to 3 weeks, exterior wall cover work can often take nearly a month.
The long construction period can be a source of stress for residents, making it one of the drawbacks.

About the Costs of Exterior Wall Covering Work
This is a table of estimated costs for exterior wall cover work.
It serves as a guideline for the costs associated with a 30-tsubo exterior wall cover method.
The cost of exterior wall cover work is determined by the following calculation:
Exterior wall area (㎡) × Siding unit price + Equipment removal and installation costs + Additional painting costs = Total amount
This is how it is calculated.
| Material | Expected Durability (Years) | Cost Assuming 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 auxiliary parts to be painted, the number of windows, and the equipment 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 difficult to find a reliable contractor, such as “where should I request this?”
The most important thing when choosing a contractor or obtaining a quote is to always obtain multiple estimates!
For this reason, when requesting exterior wall cover work, let’s confirm the following four points.
1. Check the contents and materials of the estimate
2. Confirm the existence of warranties and aftercare
3. Obtain multiple estimates from different contractors (at least three companies)
4. Check if the contractor performs the exterior wall cover work in-house
By confirming the above four points, you will be able to choose a trustworthy 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?
Check if 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, make sure the siding proposed aligns with your original needs!
・Is the proposed installation method appropriate?
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 skip the ventilation layer and apply it directly, moisture cannot escape, leading to mold or corrosion, and may cause peeling or lifting of the exterior wall material.
Check if the proposed work is appropriate!
・Are the quantities and construction details clearly specified?
If the estimate states something vague like “exterior wall cover work 1 set,” it will be difficult to understand the construction method and what the costs are for.
Having clear unit prices and quantities for items like foundation water drainage and edge trim will provide peace of mind and help prevent issues.
If there are items of concern that are not included in the estimate, ask for the reason they are not included!
・Check the auxiliary materials to be used!
Check not only the main siding 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 recommended as a fastener.
2. Confirm the existence of warranties and aftercare
When choosing a contractor for exterior wall cover work, be sure to check for warranties.
Exterior wall cover work is one of the more expensive types of exterior renovations, so in addition to checking for manufacturer warranties, also confirm 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 range is typical.
Additionally, some contractors offer after-sales service separate from warranties, so be sure to check if the contractor you are considering has after-sales service.
Kakeru Koumuten Co., Ltd. always provides a warranty for exterior wall cover work.
We also offer after-maintenance services, and we send out annual direct mail, so if desired, annual inspections are possible.
3. Obtain estimates from multiple contractors (at least 3 companies)
When requesting exterior wall cover work, be sure to get estimates from multiple contractors.
The cost of the same repair can vary between contractors, as can the warranties and after-sales services they offer.
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 auxiliary materials!
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 other issues with external contractors.
Moreover, if problems arise after the work is completed, the response may be slow, or there may be no dealings with the external contractor, leading to potential troubles.
Being able to respond immediately when something goes wrong is one of the reasons why companies that perform the work in-house are recommended!
