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 a construction 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 cover method are generally lightweight and durable metal siding.

Although 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 cover method so popular?

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

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 properties are 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, 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 effectiveness!

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 to match the atmosphere of the 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 of interest in the catalog, you can also request cut samples!

What to be cautious about 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 contractors have limited experience, which can lead to frequent issues.
Since there is often a wide variation in estimated costs, to ensure a satisfactory construction, if you are considering the exterior wall cover method with metal siding, it is advisable 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 is arguably the most extensive type of exterior renovation.
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.

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 in choosing a contractor and obtaining estimates is to always obtain multiple estimates!

For this reason, when requesting exterior wall cover work, let’s confirm the following 4 points.

By confirming the above 4 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 the ventilation layer and apply it directly, moisture cannot escape, which can lead 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 described in detail?

If the content is vague, such as “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 clear unit prices and quantities for items like foundation water drainage and edge lengths will provide peace of mind and may help prevent issues.
If there are items of concern that are not included in the estimate, confirm the reason for their exclusion!

・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, 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 existence of guarantees and aftercare maintenance

When choosing a contractor for exterior wall cover work, make sure to check for warranties.

Exterior wall cover work is a significant investment in exterior remodeling, so in addition to the manufacturer’s warranty, be sure to confirm whether the contractor offers their 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 includes a warranty with their exterior wall cover work.
We also provide after-maintenance services, sending 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 get estimates from multiple contractors.

Even for the same repair work, the costs can vary between contractors, as can the warranties and after-sales services.

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

To request your preferred contractor at the best possible price, obtaining estimates from multiple companies is essential.
When comparing estimates, consider not only the costs but also the details of the plans, materials, and ancillary 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 to external companies, and there is a higher likelihood of issues such as miscommunication with external contractors.

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