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 a construction method that overlays a new exterior wall on top of 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 wall cover 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 cover method popular?

We will introduce the “five points” that have received praise for Kakeru Koumuten Co., Ltd.’s exterior wall cover method!

Point 1　Super high durability!!

Metal siding offers an overwhelmingly high expected durability compared to exterior 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, 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 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 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 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 brand-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 Industry“, “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 are the points 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!

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 inexperienced contractors exist, 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 drawbacks.
If noticeable scratches occur and are a concern, you can 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 close to a month.
The long construction period can be a source of stress for residents, making it one of the disadvantages.

It serves as a cost estimate for performing the roof overlay (cover method) on a building with a total 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.

Galvalume Steel	30 to 35	Including Tax Approximately 2,000,000 yen (Siding unit price 11,000 yen/m² and up)

Please note that this is just a guideline for the cost, and a detailed estimate is 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?”
The most important thing when selecting a contractor and 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.

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 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 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 skip creating a ventilation layer and apply it directly, moisture cannot escape, leading to mold or corrosion, and may cause peeling or lifting of the exterior wall material.
Check whether the proposed work is appropriate!

・Are the quantities and construction details specified 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 base water cutting and edge lengths will provide peace of mind and help prevent issues.
If there are items of concern 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 seem cheaper at first glance, stainless steel is 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 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 common.

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 provides a warranty for exterior wall cover work.
We also conduct after-maintenance, and we send out annual direct mail, 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 get estimates from multiple contractors.

The cost of the same repair can vary between contractors, as can warranties and after-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 supplies!

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 also a higher likelihood of miscommunication 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 issues arise is one of the reasons why companies that perform the work in-house are recommended!
