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

Estimates and consultations are free!
Multiple estimates are very welcome!

What is the exterior wall covering method?

We will explain in detail the recommended points and precautions of the exterior wall covering method!

The exterior wall covering method is the process of overlaying a new exterior wall over 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 covering method are generally lightweight and durable metal siding.

Although the cost is 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 covering method so popular?

Here are the “five points” that have received praise for Kakeru Koumuten’s exterior wall covering method!

Point 1 Super high durability!!

Metal siding offers an overwhelmingly higher 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 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 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 level of peace of mind for long-term exterior renovations!

Point 4　Improved Waterproofing!!

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

Point 5　Improved Aesthetics!!

Various designs such as wood grain and tile patterns

Metal siding allows for a finish that resembles 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“, “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 while looking at the catalog, you can also request cut samples!

What to be aware of when performing exterior wall cover work with metal siding?

Next, I 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 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 likelihood 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!

Caution 2　Prone to dents and scratches

Metal siding may 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!

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 Cost of Exterior Wall Covering Work

This is a guideline table for the costs associated with exterior wall cover work.
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 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 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 attached parts to be painted, the number of windows, and the equipment to be removed or installed.
Please note that this is just a rough estimate, and detailed quotes 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 reputable contractor, such as “where should I request?”
The most important thing when selecting a contractor or obtaining a quote is to definitely obtain multiple quotes!

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

By confirming the above four points, you will be able to choose a reliable 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 the siding proposed aligns with your original needs!

・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 apply the new siding directly without a ventilation layer, moisture cannot escape, which may 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.
Having clear descriptions of unit prices and quantities for items like foundation water drainage and trim lengths will provide reassurance and help prevent issues.
If there are items of concern that are not included in the estimate, check 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 resistant to rust and is a 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 checking for manufacturer warranties, 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 period is typical.

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 offer after-maintenance services and send out annual DM, so if you wish, 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 obtain estimates from multiple contractors.

The cost of the same repair can vary between contractors, as well as 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 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 will be cost differences 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 issues arising with external contractors.

Moreover, if problems occur after the work is completed, the response may be slow, or the company may not have dealings with the external contractor, leading to potential troubles.
One of the reasons to recommend companies that perform the work in-house is that they can respond quickly if any issues arise!
