“Beautiful finish like a new building that cannot be achieved with exterior painting”
Exterior wall cover construction is gaining attention year by year.
Here, we will also introduce case studies, benefits, points to note, and costs!
This will definitely be helpful for customers considering exterior siding in Kita-ku, Tokyo, so please take a look!
The most important thing to consider when thinking about exterior siding is “multiple estimates”!
Let’s get at least three estimates from exterior renovation companies that cover the Kita area!
Estimates and consultations are free!
Multiple 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 the construction of overlaying a new exterior wall over 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 wall 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 wall cover method so popular?
Here are the “five points” that have received praise for Kakeru Koumuten’s exterior wall cover method!
Point 1 Super high durability!!
Metal siding offers significantly higher durability compared to exterior painting.
Galvalume steel, SGL steel, and aluminum are 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.
Moreover, by installing furring strips before the metal siding installation to create a ventilation layer, the insulation properties are 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 painting, manufacturer warranties are generally not included.
Metal siding comes with solid manufacturer warranties, such as coating and puncture warranties, 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, significantly 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 brand new construction, which cannot be achieved with exterior painting.
There are various designs available, ranging from simple styles to tile 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“, “Nichiwa“, and “Asahi Tostem“, each offering a wide 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 aware of when performing exterior wall cover work with metal siding?
Next, we will explain the “three points to be aware of” when using metal siding for exterior wall cover work!
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 estimated costs, to ensure a satisfactory construction, if you are considering the exterior wall cover method with metal siding, be 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, it is possible to request repairs from a specialized repair contractor!
Point 3 Long construction period
Exterior wall cover work is arguably the most extensive type of exterior renovation.
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 drawbacks.

About the Costs of Exterior Wall Covering Work
This is a table of estimated costs for exterior wall cover work.
It serves as a cost estimate for performing the roof overlay (cover method) on a building with a total 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 costs + Additional painting costs = Total amount.
| 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 | Over 40 years | Including Tax Approximately 2,500,000 yen (Siding unit price 14,000 yen/㎡~) |
The amount will vary depending on the number of painted accessories and windows, as well as the equipment to be removed and reattached.

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 check the following four points.
1. Check the contents and materials of the estimate
2. Confirm the existence of warranties and aftercare maintenance
3. Obtain multiple quotes from different 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 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 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, making it hard to compare estimates.
Having clear unit prices and quantities for items like base 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, 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, 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 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 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 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 the warranty, 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 offer after-maintenance services and send out annual direct mail, so if you wish, you can have inspections 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 can the warranties and after-sales services they offer.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower 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 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 the company may not have dealings with the external contractor, leading to further complications.
Being able to respond quickly in case of issues is one of the reasons why companies that perform the work in-house are recommended!
