For customers considering exterior siding in Taito-ku, Tokyo, this will definitely be helpful 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 serve the Taito-ku area!
Estimates and consultations are free!
Multiple estimates are very welcome!
What is the exterior cover method?
We will explain in detail the recommended points and precautions of the exterior cover method!
The exterior cover method is a construction 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 cover 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 cover method so popular?
Here are the “five points” that have made Kakeru Koumuten’s exterior cover 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, 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 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 painting, manufacturer warranties are generally not included.
Metal siding comes with solid manufacturer warranties such as coating warranties and hole warranties, providing a high level of reassurance for long-term exterior renovations!
Point 4 Improved Waterproofing!!
With the exterior 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 new construction, which cannot be achieved with exterior painting.
There are various designs available, ranging from simple 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 Industrial“, “Keimyuu“, “Nichiwa“, and “Asahi Tostem“, each offering a wide range of types and designs of metal siding.
If you’re interested in a product 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 installation
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 can be a lot of variation in estimate costs, to ensure a satisfactory construction, 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 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 can be considered one of the most extensive renovations in exterior remodeling.
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 guideline table for the costs when performing exterior wall cover work.
It serves as a cost estimate for a 30-tsubo exterior wall cover method.
The cost of the exterior wall cover work will be determined by the calculation below.
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 | 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 attached parts to be painted, the number of windows, and the equipment to be removed or installed.
This is just a rough estimate, so for a detailed quote, please feel free to contact us as it is completely free of charge.
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 4 points.
1. Check the contents and materials of the estimate
2. Confirm the existence of warranties and aftercare services
3. Obtain multiple quotes from several 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!
There are various types of metal siding, such as cost-effective siding and insulation-focused siding, so make sure to verify if the proposed siding meets your original requirements!
・Is the proposed installation 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 skip the ventilation layer and apply it directly, moisture cannot escape, leading to mold or corrosion, and may result in peeling or lifting of the exterior wall material.
Check if the proposed work is appropriate!
・Are the quantities and construction details clearly stated?
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 foundation water drainage and edge lengths will provide reassurance and help prevent issues.
If there are items of concern that are not included in the estimate, check the reason for their exclusion!
・Also check the auxiliary materials to be used!
Check not only the siding itself 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 differ 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 services
When choosing a contractor for exterior wall covering work, be sure to check for warranties.
Exterior wall covering work is a significant investment in exterior remodeling, so in addition to the manufacturer’s warranty, 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 covering work.
We also conduct after-maintenance and send out annual direct mail, so if desired, annual inspections are possible.
3. Obtain estimates from multiple contractors (at least 3 companies)
When requesting exterior wall covering 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 offered.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your preferred 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 covering 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 issues such as miscommunication with external contractors.
Furthermore, if problems arise after construction, the response may be slow, or the company may not have dealings with the external contractor, leading to potential troubles.
One of the reasons to recommend companies that perform the work in-house is that they can respond quickly if something goes wrong!
