The most important thing when considering exterior wall siding is “getting multiple estimates”!
Let’s obtain at least three estimates from exterior renovation companies that cover Meguro-ku!
Estimates and consultations are free!
We welcome multiple estimates!
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.
Although the cost is 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 “five points” that make Kakeru Koumuten’s exterior wall cover method well-received!
Point 1 Super high durability!!
Metal siding offers significantly higher durability compared to exterior 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 cover method comes with integrated insulation.
Moreover, by installing battens before the metal siding, a ventilation layer is created, significantly enhancing insulation!
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 perforation guarantees, 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 Enhanced Aesthetics!!
Various designs such as wood grain and tile patterns
Metal siding allows for a finish that resembles 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 that match the atmosphere and your preferences for the building!
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 to be aware of when doing exterior wall cover work with metal siding?
Next, we will explain the “three points to be cautious about” when using metal siding for exterior wall 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 troubles.
Since there is often a variation in estimated costs, to ensure a satisfactory project, if you are considering the exterior wall cover method with metal siding, make sure to get 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 if 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 nearly 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 serves as a cost estimate for performing the roof overlay (cover method) on a 30-tsubo building.
The cost of the exterior wall cover work will be estimated based on 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/m²～) |
| SGL Steel | 35 to 40 | Including Tax Approximately 2,200,000 yen (Siding unit price 12,500 yen/m²～) |
| Aluminum | 40 or more | Including Tax Approximately 2,500,000 yen (Siding unit price 14,000 yen/m²～) |
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 an Exterior Siding Contractor
There are fewer contractors that handle exterior cover work compared to exterior painting contractors, so it may be challenging to find a reliable contractor, such as “where should I request?”
The most important thing when selecting a contractor and obtaining a quote is to always obtain multiple estimates!
For this reason, when requesting exterior 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 estimates from multiple contractors (at least three companies)
4. Verify whether the contractor performs exterior 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 cover work, let’s check the following items!
・Is the proposed new siding material suitable for your requirements?
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 the siding proposed aligns with your original requirements!
・Is the proposed construction method appropriate?
When performing exterior 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 skip creating a ventilation layer and directly attach the material, moisture cannot escape, leading to mold, corrosion, or potential peeling and lifting of the exterior material.
Confirm whether the proposed construction is appropriate!
・Are the quantities and construction details described in detail?
If the estimate states something vague like “exterior 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 stops and edge trims 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, the 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 existence of warranties 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 types of exterior renovations, so in addition to checking for manufacturer warranties, also 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-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 desired, annual inspections can be arranged.
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 warranties and after-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 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 miscommunication and other issues with external contractors.
Moreover, 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 immediately in case of issues is one reason why companies that perform the work in-house are recommended!
