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 one.
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 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 popular?

We will introduce the “5 points” that make Kakeru Koumuten Co., Ltd.’s exterior wall cover method well-received!

Point 1　Super high durability!!

Metal siding offers an overwhelmingly high expected durability compared to exterior wall 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 wall 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 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 wall painting, manufacturer warranties are generally not included.
Metal siding comes with solid manufacturer warranties such as coating warranties and hole warranties, providing a high sense of security for long-term exterior renovations!

Point 4　Improved Waterproofing!!

With the exterior wall material being double-layered, it significantly prevents rainwater intrusion, 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 is impossible to achieve 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 preferences!
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 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!

Point 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 is often a variation in estimated 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 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

It serves as a cost estimate for performing the exterior wall overlay (cover method) on a building with a floor area of 30 tsubo.

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 years	Including tax Approximately 2,000,000 yen (Siding unit price 11,000 yen/m²~)
SGL Steel	35 to 40 years	Including tax Approximately 2,200,000 yen (Siding unit price 12,500 yen/m²~)
Aluminum	40 years 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 auxiliary parts to be painted, the number of windows, and the equipment to be removed and reattached.
Please note that this is just a guideline amount, and detailed estimates are completely free, so feel free to contact us.

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 this?”
The most important thing when selecting a contractor or obtaining an estimate is to always obtain multiple estimates!

For this reason, when requesting exterior wall cover work, let’s check the following four points.

By checking 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 requirements?

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 proposed siding aligns with your original requirements!

・Is the proposed construction 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 do not create a ventilation layer and directly attach the material, moisture cannot escape, leading to mold or corrosion, and it may cause peeling or lifting of the exterior wall 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 wall cover work 1 set,” it will be difficult to understand the construction method and what the costs are for.
Having clear descriptions of the lengths of foundation water cuts and edge trims, along 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!

・Check the auxiliary materials to be used!

Check the types of “furring strips“, “siding fasteners“, and “types of waterproof paper“, not just the siding itself, but also the types of detailed auxiliary materials!
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 the recommended fastener.

2. Confirm the presence of guarantees 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 renovations, so in addition to checking for manufacturer warranties, also confirm whether the company offers its own warranty!
For contractors that provide a warranty period, repairs may be done for free within that warranty 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-service separate from warranties, 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, inspections can be done 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.

The cost of the same repair can vary between contractors, as can warranties and after-service options.

Additionally, obtaining multiple estimates makes it easier to negotiate prices.

To request your desired repair contractor at the lowest 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 cost differences between companies that handle the work in-house and those that outsource to external companies, and there is a higher likelihood of communication errors and other issues with external contractors.

Moreover, if problems arise after construction, responses may be delayed, or there may be no dealings with the external construction company, leading to further complications.
Being able to respond immediately when something goes wrong is one of the reasons why companies that perform the work in-house are recommended!
