Comparative 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 process that overlays a new exterior wall on top of the existing wall.
It is possible to overlay various types of 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 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 wall cover method so popular?
Here are the “five points” that Kakeru Koumuten’s exterior wall cover method is highly praised for!
Point 1 Super high durability!!
Metal siding offers significantly higher durability compared to exterior painting.
Made of Galvalume steel, SG 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 cover method comes with integrated insulation material.
Moreover, by installing battens before the metal siding, a ventilation layer is created, significantly enhancing insulation!
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 level of reassurance for long-term exterior renovations!
Point 4 Improved Waterproofing!!
With the exterior material being double-layered, it effectively prevents rainwater intrusion, greatly enhancing waterproofing.
Applying waterproof paper before installation further increases waterproofing!
Point 5 Improved Aesthetics!!
Various designs such as wood grain and tile patterns
Metal siding allows for a finish that resembles a new construction, which cannot be achieved with exterior painting.
There are various designs available, ranging from simple to tile 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 various 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 cautious about when doing exterior wall cover work with metal siding?
Next, I will explain the “three points of caution” 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 is often a variation in estimation 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 can be considered the most extensive among exterior renovations.
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 drawbacks.

About the Costs of Exterior Wall Covering Work
This is a reference table for the estimated costs of exterior wall cover work.
It is 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 calculation below.
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.
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 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 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 existence of warranties and aftercare
3. Obtain multiple quotes from several 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 needs?
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 siding proposed aligns with your original requirements!
・Is the proposed construction 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 a ventilation layer, moisture cannot escape, leading to mold or corrosion, and it may result in peeling or lifting of the exterior wall material.
Check whether the proposed construction is appropriate!
・Are the quantities and construction details described in detail?
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 lengths will provide peace of mind and help prevent issues.
If there are items of concern that are not included in the estimate, be sure to confirm the reasons for their exclusion!
・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, the 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. 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 types of exterior renovations, so in addition to checking for manufacturer warranties, also confirm if the company offers its 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 period 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 includes a warranty with exterior wall cover work.
We also provide after-maintenance services and 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.
Even for the same repair, the costs can vary between contractors, as can the warranties and after-sales services.
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 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 a higher likelihood of miscommunication and other issues with external contractors.
Additionally, if problems arise after construction, the response may be slow, or there may be no dealings with the external construction company, 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!
