What is the exterior cover method?
We will explain in detail the recommended points and precautions of the exterior cover method!
The exterior cover method is a construction process that overlays a new exterior wall on top of the existing exterior wall.
It can be applied to various types of exterior walls such as ALC walls, ceramic siding, and mortar walls.
The exterior materials used in the exterior cover method are generally lightweight and durable metal siding.
Although the costs are 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 cover method popular?
We would like to introduce the “5 points” that have received positive feedback for Kakeru Koumuten’s exterior cover method!
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, 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 wall cover method comes with integrated insulation material.
Moreover, by installing battens before the metal siding construction to create a ventilation layer, the insulation performance is significantly improved!
This enhancement 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 and perforation guarantees, providing a high level of reassurance for long-term exterior renovations!
Point 4 Improved Waterproofing!!
With the exterior wall material being double-layered, it effectively prevents rainwater intrusion, significantly enhancing waterproofing.
Applying waterproof paper before construction further increases waterproofing performance!
Point 5 Enhanced Aesthetic Appeal!!
Various designs such as wood grain and tile patterns
Metal siding allows for a finish that resembles a new build, 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 that match the atmosphere and your preferences of the building!
Major manufacturers include Aiji Industrial, Keimyuu, Nichiwa, and Asahi Tostem, each offering a range of types and designs of metal siding.
If you find a product of interest in the catalog, you can also request cut samples!
What are the points to be cautious about when doing exterior wall cover work with metal siding?
Next, I will explain the “three points to be cautious about” when performing exterior wall cover work using metal siding!
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 be a lot of variation in estimate 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!
Caution 2 Prone to dents and scratches
Metal siding can develop dents from impacts if objects hit it.
Additionally, being prone to scratches is one of its drawbacks.
If noticeable scratches occur and are a concern, it is possible to request repairs from a specialist repair contractor!
Caution 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 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 guide for the estimated costs of exterior wall cover work.
It serves as a cost estimate for performing the exterior wall cover method on a building with a floor area of 30 tsubo.
The cost of exterior wall cover work will be estimated based on the following calculation.
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 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.
Please note that this is just a rough estimate, and detailed quotations 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 difficult 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 confirm the following four points.
1. Confirm the contents and materials of the estimate
2. Check for warranties and aftercare services
3. Obtain multiple quotes from several contractors (at least three)
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. Confirm 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 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 apply it directly without creating a ventilation layer, moisture cannot escape, which can lead 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 drainage and trim lengths will provide peace of mind and help prevent issues.
If there are items of concern that are not included in the estimate, check the reasons for their exclusion!
・Also 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 seem cheaper at first glance, stainless steel is resistant to rust and is the recommended fastener.
2. Check for warranties and aftercare services
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 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.
Warranty periods vary by contractor and the specifics of the work, but a 5 to 10-year setting is common.
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 conduct after-maintenance, and we send out annual DM, so if you wish, annual inspections are possible.
3. Obtain estimates from multiple contractors (at least 3 companies)
When requesting exterior wall cover work, be sure to obtain estimates from multiple contractors.
Even for the same repair work, the costs may vary between contractors, as well as the warranties and after-sales services offered.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower cost, 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 in-house construction and those that outsource to external companies, and issues such as miscommunication with external contractors are more likely to occur.
Moreover, if problems arise after construction, the response may be slow, or there may be no dealings with external construction companies, leading to potential troubles.
One of the reasons we recommend companies that perform in-house construction is that they can respond immediately if something goes wrong!
