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 process that overlays a new exterior wall on top of the existing exterior wall.
It is possible to overlay 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.

While the costs are 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 popular?

Here are the “five points” that explain why Kakeru Koumuten’s exterior wall cover method is well-received!

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, which is 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 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, including 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　Improved Aesthetic Appeal!!

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 styles to tile and wood grain patterns.
You can choose from a variety of designs to match the atmosphere of your building and your 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 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 methods!

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, which can lead to frequent troubles.
Since there is often a wide 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!

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 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 reference table for the estimated costs of 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 exterior wall cover work is determined by the calculation below.
Exterior wall area (㎡) × Siding unit price + Equipment removal and installation cost + Additional painting cost = Total amount
This is how it is calculated.

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/m²～)

The amount will vary depending on the number of auxiliary parts to be painted, the number of windows, and the equipment to be removed and reattached.
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 reputable contractor, such as “where should I request it?”
The most important thing in choosing a contractor and 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.

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 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 it proposed with the appropriate construction method?

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 do not create a ventilation layer and directly attach the material, moisture cannot escape, which can lead to mold, corrosion, or peeling and lifting of the exterior wall material.
Check whether the proposed work is appropriate!

・Are the quantities and construction details described in detail?

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 the lengths of base water cuts and edge trims clearly listed 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, 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 more resistant to rust and is a recommended fastener.

2. Confirm the existence of warranties and aftercare services

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 the manufacturer’s warranty, 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 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 direct mail, so if desired, annual inspections are possible.

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 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 issues such as miscommunication with external contractors can easily arise.

Additionally, if problems occur after construction, responses may be slow, or there may be no dealings with external construction companies, leading to potential troubles.
Being able to respond immediately when something happens is one of the reasons why companies that perform in-house construction are recommended!
