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 the process of overlaying a new exterior wall over the existing exterior wall.
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.
While the costs are higher compared to exterior painting, it is a renovation method for exteriors that has various benefits and is gaining attention year by year.
Why is the exterior covering method popular?
We would like to introduce the “5 points” that have made Kakeru Koumuten’s exterior covering 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, or 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 furring strips before the metal siding installation 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 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 peace of mind 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 effectiveness!
Point 5 Improved Aesthetic Appeal!!
Various designs such as wood grain and tile patterns
Metal siding allows for a finish that resembles a 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 Industry, Keimyuu, Nichihara, 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 looking at 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 aware of” when performing exterior wall cover work using metal siding!
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, which can lead 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 drawbacks.
If noticeable scratches occur and are a concern, you can request repairs from a specialized repair contractor!
Point 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 nearly a month.
The long construction period can be a source of stress for residents, making it one of the disadvantages.

Exterior wall area (㎡) × Siding unit price + Equipment removal and installation costs + Additional painting costs = Total amount
This will be the total.

Please note that this is just a guideline for the cost, and detailed estimates 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 when selecting a contractor or obtaining an estimate is to always obtain multiple estimates!
For this reason, when requesting exterior wall cover work, let’s check the following 4 points.
1. Check the contents and materials of the estimate
2. Confirm the existence of warranties and aftercare maintenance
3. Obtain multiple estimates from different contractors (at least 3 companies)
4. Check if the contractor performs the exterior wall cover work in-house
By confirming the above 4 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 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 the 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 construction method.”
If you apply it directly without creating a ventilation layer, moisture cannot escape, which can lead to mold and corrosion, or cause peeling and lifting of the exterior wall material.
Check if the proposed construction 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 the lengths of the base water cut and edge trim clearly listed with unit prices and quantities 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 a recommended fastener.
2. Confirm the existence of warranties and aftercare maintenance
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 the manufacturer’s warranty, be sure to confirm whether the company offers its own warranty!
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 typical.
Additionally, some contractors offer after-service separate from the warranty, so be sure to check if the contractor you are considering has after-service available.
Kakeru Koumuten Co., Ltd. always provides a warranty for exterior wall cover work.
We also conduct after-maintenance and 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, the construction costs may vary by contractor, and warranties and after-services may differ as well.
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 plan details, materials, and ancillary 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 also a higher likelihood of issues such as miscommunication with external contractors.
Furthermore, 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 happens is one of the reasons why companies that perform the work in-house are recommended!
