What is the Exterior Wall Cover Method?
We will explain the recommended points and precautions of the exterior wall cover method in detail!
The exterior wall cover method is a construction process that overlays a new exterior wall on top of the existing wall.
It can be applied to various types of walls, including ALC walls, ceramic siding, and mortar walls.
The materials used for the exterior wall cover method are generally lightweight and durable metal sidings.
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 Popular?
Here are the “5 Points” that make Kakeru Koumuten’s exterior wall cover 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 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 wall 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 reassurance for long-term exterior renovations!
Point 4 Improved Waterproofing!!
With the exterior wall material being double-layered, it significantly enhances waterproofing by preventing rainwater intrusion.
Applying waterproof paper before installation further increases waterproofing effectiveness!
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 and your preferences of the building!
Major manufacturers include “Aiji Industrial“, “Keimyuu“, “Nichiwa“, and “Asahi Tostem“, each offering a wide 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, I will explain the “three points to be cautious about” when performing exterior wall cover work using metal siding!
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 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, 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 specialized repair contractor!
Caution 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 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 table of estimated costs for 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 the exterior wall cover work will be determined by the following calculation:
Exterior wall area (㎡) × Siding unit price + Equipment removal and installation cost + Additional painting cost = 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 years | Including tax Approximately 2,000,000 yen (Siding unit price 11,000 yen/㎡~) |

The amount will vary depending on the number of attached parts and windows to be painted, 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 when choosing a contractor or 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 presence of guarantees and aftercare maintenance
3. Obtain multiple quotes from several contractors (at least three companies)
4. Confirm whether the contractor performs the exterior wall cover work in-house
By checking 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 a ventilation layer, moisture cannot escape, leading to mold and corrosion, or possibly causing 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 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 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 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 presence of guarantees and aftercare maintenance
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 renovations, so in addition to the manufacturer’s warranty, make sure to check if 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 type of work, but a 5 to 10-year period is common.
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 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-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 company 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 miscommunication and issues arising 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 potential troubles.
Being able to respond quickly when issues arise is one of the reasons why companies that perform in-house construction are recommended!
