What is the exterior covering method?
We will explain in detail the recommended points and precautions of the exterior covering method!
The exterior covering method is a construction process that overlays a new exterior on top of the existing exterior.
It is possible to overlay various types of exteriors such as ALC walls, ceramic siding, and mortar walls.
The exterior materials used in the exterior covering 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 covering method so popular?
Here are the “5 points” that make Kakeru Koumuten’s exterior covering 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, 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 has integrated insulation material.
Moreover, by installing battens before the metal siding installation to create a ventilation layer, the 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 wall 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 effectively prevents rainwater intrusion, significantly enhancing waterproofing.
Applying waterproof paper before installation further increases waterproofing performance!
Point 5 Enhanced Aesthetics!!
Various designs such as wood grain and tile patterns
Metal siding allows for a finish that resembles 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 Industrial, Keimyuu, Nichiwa, and Asahi Tostem, each offering a variety of types and designs of metal siding.
If you find a product of interest in the catalog, you can also request cut samples!
What to Watch Out for When Performing Exterior Cover Work with Metal Siding?
Next, we will explain the “three points of caution” when using metal siding for exterior cover work!
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 problems.
Since there is often a wide range of estimates, to ensure a satisfactory project, if you are considering the exterior cover method with metal siding, be 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 disadvantages.
If noticeable scratches occur and are a concern, you can request repairs from a specialist repair contractor!
Caution 3 Long Construction Period
Exterior 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 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.

It serves as a cost estimate for 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

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 reputable contractor, such as “where should I request?”
The most important thing in choosing a contractor and obtaining estimates is to always obtain multiple estimates!
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 guarantees and aftercare
3. Obtain multiple estimates 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 reliable 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 that the siding proposed aligns with your original requirements!
・Is it proposed with an appropriate construction method?
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, corrosion, or peeling and lifting of the exterior wall material.
Check whether the proposed work is appropriate!
・Are the quantities and construction details described in detail?
If the description 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 edge trim will provide peace of mind and help prevent issues.
If there are items of concern that are not included in the estimate, check the reason for their exclusion!
・Check the auxiliary materials to be used!
Check not only the siding itself but also the types of detailed auxiliary materials, such as “type of battens,” “siding fasteners,” and “type of waterproof paper“!
For example, the siding fasteners are screws, and the overall cost can 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 guarantees 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 period 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 includes a warranty with exterior wall cover work.
We also provide after-maintenance services, and we 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 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 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 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, and there is a higher likelihood of issues arising from miscommunication with external contractors.
Additionally, if problems occur after construction, responses may be delayed, or there may be no dealings with the external construction company, leading to further complications.
Being able to respond immediately in case of issues is one of the reasons why companies that perform in-house construction are recommended!
