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 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.
While the costs are higher compared to exterior painting, it is a method of exterior remodeling that has various benefits and is gaining attention year by year.
Why is the exterior wall cover method so popular?
We would like to introduce the “5 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 wall painting.
Made of Galvalume steel, SGL steel, and aluminum, there are various types of metal siding, and 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 wall cover method comes with integrated insulation material.
Moreover, by installing battens before the metal siding installation to create a ventilation layer, the insulation properties are 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 wall painting, manufacturer warranties are generally not included.
Metal siding comes with solid manufacturer warranties such as coating warranties and hole warranties, providing a high level of reassurance for long-term exterior renovations!
Point 4 Improved Waterproofing!!
With the exterior material being double-layered, it effectively 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 cannot be achieved 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 browsing the catalog, you can also request cut samples!
What are the points to be careful about when doing exterior wall cover work with metal siding?
Next, I will explain the “three points to be careful about” when using metal siding for exterior wall cover methods!
Point 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 is often a variation in the estimated costs, to ensure a satisfactory construction, if you are considering the exterior wall cover method with metal siding, make sure to obtain estimates from three or more companies and carefully review the details!
Point 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, it is possible to request repairs from a specialized repair contractor!
Point 3 Long construction period
Exterior wall cover work can be considered one of the most extensive renovations in exterior remodeling.
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 disadvantages.

About the Costs of Exterior Wall Covering Work
This is a guideline table for the estimated costs of exterior wall cover work.
It is an estimate for the cost of performing the exterior wall overlay (cover method) on a building with a floor area of 30 tsubo.
The cost of the exterior wall cover work will be estimated based on the calculation below.
Exterior wall area (㎡) × Siding unit price + Equipment removal and installation costs + Additional painting costs = 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 | Including Tax Approximately 2,000,000 yen (Siding unit price 11,000 yen/㎡~) |
| SGL Steel | 35 to 40 | 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.
Please note that this is just a rough estimate, and detailed quotes are completely free, so feel free to contact us.
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 reliable contractor, such as “where should I request?”
The most important thing in choosing a contractor and obtaining a quote is to always obtain multiple quotes!
For this reason, 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 existence of warranties and aftercare
3. Obtain multiple quotes from different contractors (at least three companies)
4. Confirm whether 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 requirements?
Check whether 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 that the proposed siding aligns with your original requirements!
・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 result in peeling or lifting of the exterior wall material.
Check whether the proposed work is appropriate!
・Are the quantities and construction details specified in detail?
If the estimate states something vague like “exterior wall cover work 1 set,” it becomes 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 stops and edge trims can provide peace of mind and help prevent issues.
If there are items of concern not included in the estimate, confirm the reason for their exclusion!
・Also check the auxiliary materials 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 can vary between iron and stainless steel.
While iron may appear cheaper at first glance, stainless steel is resistant to rust and is a recommended fastener.
2. Confirm the existence of warranties and aftercare
When choosing a contractor for exterior wall cover work, make sure to check for warranties.
Exterior wall cover work is one of the more expensive renovations, so in addition to manufacturer warranties, also check for the presence of in-house warranties!
If the contractor has a warranty period, they may offer 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 confirm if the contractor you are considering has after-sales services.
Kakeru Koumuten Co., Ltd. always provides a warranty for exterior wall cover work.
We also conduct after-maintenance, and we send out annual DM, so if desired, inspections can be done every year.
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 cost of the same repair can vary between contractors, as can warranties and after-sales services.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower cost, obtaining estimates from several 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 contractor performs exterior wall cover work in-house
There are differences in costs between companies that handle in-house construction and those that outsource to external companies, which can also lead to miscommunication and other issues with external contractors.
Furthermore, if problems arise after construction, responses may be delayed, or there may be no dealings with external construction companies, leading to potential troubles.
Being able to respond immediately when something happens is one of the reasons why companies that perform in-house construction are recommended!
