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 Katsushika!
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 that overlays a new exterior wall on top of the existing exterior wall.
It can be applied to various types of 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?
We will introduce the “five points” that have received positive feedback for Kakeru Koumuten’s exterior wall cover method!
Point 1 Super high durability!!
Metal siding offers significantly higher durability compared to exterior painting.
Made of Galvalume steel, SGL steel, or aluminum, there are various 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 material.
Moreover, by installing furring strips before the metal siding installation 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 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 effectiveness!
Point 5 Improved Aesthetics!!
Various designs such as wood grain and tile patterns
Metal siding allows for a finish that resembles a new build, 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 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, we will explain the “three points to be aware of” when performing exterior wall cover work using metal siding!
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 estimation 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 disadvantages.
If noticeable scratches occur and are a concern, you can 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 disadvantages.

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 confirm the following 4 points.
1. Check the contents and materials of the estimate
2. Confirm the existence of warranties and aftercare
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!
Since there are various types of metal siding, such as cost-effective siding and insulation-focused siding, confirm whether the siding proposed aligns with your original requirements!
・Is the proposed construction method appropriate?
When performing exterior wall cover work, it is necessary to establish a ventilation layer between the existing exterior wall and the new exterior wall material using a method called “ventilation method.”
If you do not create a 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 whether the proposed construction is appropriate!
・Are the quantities and construction details clearly specified?
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 the lengths of base water cut and trim edges clearly stated with unit prices and quantities 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!
・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, 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 a recommended fastener.
2. Confirm the existence of warranties and aftercare
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 manufacturer warranties, 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 depending on the contractor and the scope of 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 includes a warranty with its exterior wall cover work.
We also provide after-maintenance, and we send out annual direct mail, so if desired, 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 get estimates from multiple contractors.
Even for the same repair, the costs can vary between contractors, as well as the warranties and after-services offered.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired contractor at a lower price, obtaining estimates from multiple companies is essential.
When comparing estimates, consider not only the costs but also the plan details, materials, and auxiliary supplies!
4. Confirm if 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 issues such as miscommunication with external contractors are more likely to occur.
Moreover, if problems arise after construction, the response may be slow, or there may be no dealings with the external contractor, leading to potential troubles.
Being able to respond quickly in case of issues is one of the reasons why companies that perform the work in-house are recommended!

Katsushika Eco Subsidy for Fiscal Year 7
Requirements
Newly built houses are not eligible; it must be an insulation renovation for existing houses. A preliminary application is required before construction, and work must commence after receiving the approval notification. Eligible residences are only individual homes where the applicant resides or plans to reside within the ward, and installations through leasing or rental are not eligible. It is possible to combine with subsidies from other wards, but there are conditions such as not receiving overlapping subsidies for the same equipment or construction.
Eligible Persons
Individuals who are registered as residents in Katsushika Ward and reside or plan to reside in the target housing are eligible. Conditions include no tax arrears, consent from the owner in the case of rental housing, and not having received similar subsidies within the past 10 years.
Subsidy Rate and Amount (Upper Limit)
Subsidy Rate: 1/4 (25%) of the eligible construction costs is subsidized.
Upper limit amount (per unit): Up to 200,000 yen.
For example, in the case of a renovation of high-insulation windows (construction cost: 280,000 yen), the subsidy from Katsushika Ward would be 25% of the construction cost, amounting to 70,000 yen (rounded down below 1,000 yen). In this case, it is also possible to combine with national programs such as the “Advanced Window Renovation Project,” allowing for significant reductions in actual costs by skillfully combining the systems.
