The most important thing to consider when thinking about exterior wall siding is “multiple estimates”!

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 the process of overlaying a new exterior wall over the existing one.
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 cost is higher compared to exterior painting, it is a renovation method for exterior walls that has various benefits and is gaining attention year by year.
Why is the exterior wall cover method so popular?
We would like to 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 an overwhelmingly high expected durability compared to exterior painting.
Made of Galvalume steel, SGL steel, and 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 has integrated insulation material.
Moreover, by installing furring strips 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 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 performance!
Point 5 Improved Aesthetics!!
Various designs such as wood grain and tile patterns
Metal siding allows for a finish that resembles a 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 and your preferences for the building!
Major manufacturers include “Aiji Industrial“, “Keimyuu“, “Nichiwa“, and “Asahi Tostem“, each offering a variety of types and designs of metal siding.
If you find a product of interest in the catalog, you can also request cut samples!
What are the points to be aware of when performing 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 contractors have little experience, leading to a higher occurrence of troubles.
Since there is often a variation in estimate costs, to ensure a satisfactory construction,
if you are considering the exterior wall cover method with metal siding, make 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, it is possible to 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 nearly a month.
The long construction period can be a source of stress for residents, making it one of the disadvantages.

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 estimates is to always obtain multiple estimates!
For this reason, when requesting exterior 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 maintenance
3. Obtain multiple estimates from different contractors (at least three companies)
4. Confirm whether the contractor performs the 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 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-focused siding and insulation-focused siding, ensure that 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 material using a method called “ventilation method.”
If you skip creating a ventilation layer and apply it directly, moisture cannot escape, which can lead to mold or corrosion, and may cause peeling or lifting of the exterior material.
Check 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, making it hard to compare estimates.
Having clear unit prices and quantities for items like base 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 reason 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 “types of battens,” “siding fasteners,” and “types of waterproof paper“!
For example, 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 the recommended fastener.
2. Confirm the presence of warranties and aftercare maintenance
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, make 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 by contractor and the specifics of the work, but a 5 to 10-year setting 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 conduct after-maintenance and send out annual DM, so if you wish, you can have inspections 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 they offer.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower cost, it is essential to obtain estimates from multiple companies.
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 the work in-house and those that outsource it to external companies, and there is a higher likelihood of miscommunication and other issues with external contractors.
Additionally, if problems arise after construction, the response may be slow, or there may be no dealings with the external contractor, leading to further complications.
Being able to respond immediately when something happens is one of the reasons why companies that perform the work in-house are recommended!
