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 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 cover method are generally lightweight and durable metal siding.
Although the costs are higher compared to exterior painting, it is a method of exterior renovation that has various benefits and is gaining attention year by year.
Why is the exterior cover method popular?
Here are the “5 points” that make Kakeru Koumuten Co., Ltd.’s exterior 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, 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 has integrated insulation material.
Moreover, by installing battens before the metal siding installation to create a ventilation layer, the insulation performance significantly improves!
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 painting, manufacturer warranties are generally not included.
Metal siding comes with solid manufacturer warranties such as coating warranties and hole warranties, 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 Improved Aesthetic Design!!
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-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 Giken, Keimyuu, Nichiwa, and Asahi Tostem, each offering various 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 aware of when doing exterior wall cover work with metal siding?
Next, we will explain the “three points to be cautious of” 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 contractors have little experience, leading to a higher occurrence of troubles.
Since there is often a wide range of estimates, 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 when 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 hire a repair specialist to fix them!
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 nearly a month.
The extended 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 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 following calculation.
Exterior wall area (㎡) × Siding unit price + Equipment removal and installation cost + Additional painting cost = Total amount
This is how it is calculated.
| 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 additional parts to be painted, the number of windows, and the equipment to be removed and reattached.

How to Choose an Exterior Siding Contractor
There are fewer contractors that handle exterior 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 selecting a contractor or obtaining a quote is to always obtain multiple quotes!
For this reason, when requesting exterior 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 quotes from several contractors (at least three companies)
4. Check if the contractor performs the exterior 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 cover work, let’s check the following items!
・Is the proposed new siding material suitable for your requirements?
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 that the siding proposed aligns with your original requirements!
・Is it proposed with appropriate construction methods?
When performing exterior 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 it may cause 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 description is vague, such as “exterior 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 edge lengths will provide peace of mind and help prevent issues.
If there are items of concern not included in the estimate, check the reason 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, 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 renovations, so in addition to the manufacturer’s warranty, also confirm whether 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 services separate from warranties, so be sure to check 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 offer after-maintenance services and send out annual direct mail, so if desired, inspections can be conducted every year.
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 well as the warranties and after-sales services they offer.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired contractor at a lower price, it is essential to obtain estimates from several companies.
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 can be cost differences 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.
Furthermore, if problems arise after construction, responses may be delayed, or there may be no dealings with the external construction company, leading to potential troubles.
Being able to respond quickly in case of issues is one of the reasons why companies that perform the work in-house are recommended!
