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 wall.
It can be applied to 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 costs are 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?

Here are the “five points” that make Kakeru Koumuten’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.
Available in Galvalume steel, SGL steel, and aluminum, metal siding comes in various types, 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 wall cover method has integrated insulation material.
Moreover, by installing battens before the metal siding installation to create a ventilation layer, 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, providing a high level of reassurance for long-term exterior renovations!

Point 4　Improved Waterproofing!!

With the exterior wall material being double-layered, waterproofing is significantly enhanced to prevent rainwater intrusion.
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 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 and your preferences for the building!
Major manufacturers include “Aiji Giken“, “Keimyuu“, “Nichiwa“, and “Asahi Tostem“, each offering various 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, I will explain the “three points to be aware of” when using metal siding for exterior wall cover work!

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, which can lead to frequent troubles.
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, make sure to get 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, you can request repairs from a specialized repair contractor!

Point 3　Long construction period

The exterior wall cover work is arguably the most extensive renovation among exterior remodeling projects.
While exterior painting typically takes about 2 to 3 weeks, the 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.

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 a quote is to always 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 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 if 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 establish 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 it, moisture cannot escape, which may lead to mold, corrosion, or peeling and lifting of the exterior wall material.
Check if the proposed construction 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 trim lengths will provide reassurance and help prevent issues.
If there are items of concern that are not included in the estimate, check the reason for their exclusion!

・Also 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 the recommended fastener.

2. Confirm the existence of guarantees and aftercare

When choosing a contractor for exterior wall cover work, make 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 warranty period.

The warranty period varies by contractor and the specifics of the work, but a 5 to 10-year range 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 includes a warranty with its exterior wall cover work.
We also provide after-maintenance services, 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 three)

When requesting exterior wall cover work, be sure to get estimates from multiple contractors.

Even for the same repair, the costs may vary between contractors, as well as the warranties and after-services they offer.

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

To request your desired repair contractor at the best possible price, it is essential to obtain estimates from multiple contractors.
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 is a cost difference 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 issues arising with external contractors.

Furthermore, if problems occur after the work is completed, 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 something goes wrong is one of the reasons why companies that perform the work in-house are recommended!
