Here, we will also introduce case studies, benefits, points to note, and costs!

This will definitely be useful for customers considering exterior siding in Minamiashigara City, so please take a look!

The most important thing to consider when thinking about exterior siding is “multiple estimates”!
Let’s obtain at least three estimates from exterior renovation companies that cover Minamiashigara City!

Estimates and consultations are free!
We welcome multiple estimates!

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 the process of overlaying a new exterior wall over 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 method of exterior renovation that has various benefits and is gaining attention year by year.

Why is the exterior cover method popular?

Here are the “five points” that make Kakeru Koumuten Co., Ltd.’s exterior cover method well-received!

Point 1 Super high durability!!

Metal siding offers an overwhelmingly high expected durability compared to exterior wall painting.
Galvalume steel, SGL steel, and aluminum are 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 strengths!
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 comes with integrated insulation.
Moreover, by installing battens before the metal siding installation to create a ventilation layer, the insulation properties are 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 and perforation guarantees, making it a reassuring choice for long-term exterior renovations!

Point 4 Improved Waterproofing!!

With the exterior wall material being double-layered, it significantly prevents rainwater intrusion, thus enhancing waterproofing.
Applying waterproof paper before installation further increases waterproofing effectiveness!

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 that match the atmosphere and your preferences of the building!
Major manufacturers include “Aiji Industrial“, “Keimyuu“, “Nichihara“, 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 performing exterior wall cover work using metal siding!

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, 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!

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 concerning, you can request repairs from a specialized repair contractor!

Caution 3 Long construction period

Exterior wall cover work can be considered the most extensive among exterior renovations.
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.

Inquiry Details

I am considering a renovation of the exterior walls. I would like to use high-durability metal siding with a solid warranty.
Since this is a comparative estimate, I would like to request a quote for the same type of metal siding as the estimates from other companies.

Proposal Details
We have proposed a roof overlay method using metal siding as per your request.
You had several preferred types of metal siding, so we created separate estimates for each one!

You entrusted us with the “Aiji Industrial/SF-Gal Stage Shine” metal siding!
The above siding is made of Galvalume steel with a heat-insulating fluorine coating, and it is integrated with insulation, providing excellent thermal insulation properties.
You mentioned that you obtained estimates from three companies, and we were able to secure your order due to our competitive pricing and thorough explanations compared to other companies!

Price Range
 2,000,000 to 2,100,000 yen
Construction Period
 Approximately 3 weeks
Existing Exterior Material / New Exterior Material

 Existing exterior: ALC
 New exterior: Metal siding (Aiji Industrial/SF-Gal Stage Shine)
 Material: Galvalume steel with heat-insulating fluorine coating
 In-house warranty: 10 years
 Manufacturer warranty: 10 years for fading, 10 years for rust, 10 years for perforation
 Furring strips: Made of resin

1. Painting of Accessory Parts

We will first paint areas not covered by wall siding (such as eaves, gables, and fascia). To match the durability of the siding, we recommend using high-durability paints such as inorganic or fluorine types.

2. Removal of Equipment

We temporarily remove items that may obstruct the siding, such as rain gutters and air conditioning ducts.

3. Substrate Adjustment

If there is significant deterioration, we will perform joint sealing and adjust the substrate if the exterior wall is warped.

4. Waterproof Paper Installation (may not be necessary)

We will apply a highly breathable moisture-permeable sheet over the entire exterior wall. If the building is over 25 years old or shows significant deterioration, we recommend installing a waterproof sheet, but if there are no issues, we may proceed without it.

5. Installation of Battens

We will install battens over the entire exterior wall. The battens will be fixed at intervals of 455 mm, and we will install wider boards around the windows. If the siding used is horizontal, the battens will be installed vertically, and if the siding is vertical, the battens will be installed horizontally.

6. Metal Work Processing

We will process and install corner bases, end caps, and foundation water-cutting metal.

7. Main Construction

Finally, we will cut the siding and secure it with screws from the bottom up. Once the siding installation is complete, we will install joint covers and corners. Stainless steel screws will be used for fastening the siding materials!

8. Sealing at Various Locations

We will apply sealing to areas that require waterproofing. If the colors match, we recommend using high-durability sealing materials such as Auton Exceed or SR Seal H100, which have an expected durability of nearly 30 years.

9. Reinstallation of Equipment

We will reinstall the removed rain gutters and air conditioning ducts. If the rain gutter brackets are of the driven type, we may change them to screw-type brackets.

10. Completion

Finally, we will conduct cleaning and a review, marking the completion of the project.

About the Cost of Exterior Wall Covering Work

This is a guideline table for the costs associated with exterior wall cover construction.
It serves as 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 construction is determined by the following calculation.
Exterior wall area in square meters × 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 cost will vary depending on the number of painted accessories and windows, as well as the equipment that needs to be removed and reattached.
This is just a guideline for the price, so please feel free to contact us for a detailed estimate, which is completely free of charge.

How to Choose an Exterior Wall 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 the work?”
The most important thing when choosing a contractor or obtaining an estimate is to always obtain multiple estimates!

For this reason, when requesting exterior wall 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 services

3. Obtain multiple estimates from different contractors (at least three companies)

4. Confirm whether the contractor performs the exterior wall 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 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 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 do not create a ventilation layer and directly attach the new material, moisture cannot escape, which can lead to mold, corrosion, and may cause the exterior wall material to peel or lift.
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.
Having clear unit prices and quantities for items like foundation water drainage and edge trim will provide reassurance and help prevent issues.
If there are items of concern that are not included in the estimate, confirm the reasons for their exclusion!

・Check the auxiliary materials to be used!

Check not only the main siding 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 rust-resistant and is the recommended fastener.

2. Confirm the presence 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 check for the presence of a company warranty!
If the contractor has a warranty period, they may offer 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 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 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 construction costs may vary between contractors, and warranties and after-services may differ as well.

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, be sure to consider not only 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 in-house construction and those that outsource to external companies, and there is a higher likelihood of issues such as miscommunication with external contractors.

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