The most important thing to consider when thinking about exterior wall siding is “multiple estimates”!
Let’s obtain at least three estimates from exterior renovation companies that cover Musashimurayama City!
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 a construction method 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 wall cover method are generally lightweight and durable metal siding.
While the costs are higher compared to exterior wall 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 popular?
Here are the “five points” that have received positive feedback for Kakeru Koumuten’s exterior wall cover method!
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, which is one of its strengths!
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 comes with integrated insulation materials.
Moreover, by installing battens before the metal siding is applied 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, making it a reassuring choice for long-term exterior renovations!
Point 4 Improved Waterproofing!!
With the exterior wall material being double-layered, waterproofing is significantly enhanced to prevent rainwater intrusion.
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 build, which is impossible to achieve 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 that match the atmosphere of your building and your personal preferences!
Major manufacturers include “Aiji Giken“, “Keimyuu“, “Nichiwa“, and “Asahi Tostem“, each offering a range of 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 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 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, leading to a higher occurrence of troubles.
Since there is often a variation in the estimated costs, to ensure you have no regrets about the work,
if you are considering the exterior wall cover method with metal siding, make sure to get estimates from three or more companies and review the details carefully!
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 they are a concern, you can request repairs from a specialized repair contractor!
Point 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 two to three 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 disadvantages.

About the Costs of Exterior Wall Covering Work
This is a guideline table for the costs associated with exterior wall cover work.
It provides an estimate for the cost of performing a 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 costs + Additional painting costs = Total amount
This will be the total.
| 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 or more | 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 that needs to be removed and reattached.
Please note that this is only a rough estimate, 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 in choosing a contractor and obtaining estimates is to always obtain multiple estimates!
For this reason, when requesting exterior wall cover work, let’s confirm the following four points.
1. Check the contents and materials of the estimate
2. Confirm the presence of warranties and aftercare services
3. Obtain multiple estimates from different contractors (at least three companies)
4. Check if 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 if the proposed materials meet your requirements, such as durability and insulation!
Since there are various types of metal siding, such as cost-effective siding and insulation-focused siding, make sure the siding 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 wall and the new siding material using a method called “ventilation method.”
If you apply the siding directly without a ventilation layer, moisture cannot escape, leading to mold and corrosion, or potentially causing peeling and lifting of the siding material.
Check if the proposed construction is appropriate!
・Are the quantities and construction details clearly specified?
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 trim will provide peace of mind and help prevent issues.
If there are items of concern that are not included in the estimate, confirm the reasons 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 furring strips,” “siding fasteners,” and “type of waterproof paper“!
For example, siding fasteners are screws, and the overall cost will vary between iron and stainless steel.
While iron may appear cheaper at first glance, stainless steel is resistant to rust and is the recommended fastener.
2. Confirm the presence of warranties and aftercare services
When choosing an exterior wall cover contractor, be 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 check for the company’s 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 period 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 offer after-maintenance and send out annual DM, so if you wish, 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 the warranties and after-services offered.
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 will 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.
Moreover, if problems arise after construction, the response may be slow, or there may be no dealings with the external construction company, leading to further complications.
Being able to respond quickly when issues arise is one of the reasons why companies that perform the work in-house are recommended!
