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.

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 wall cover method popular?

Here are the “5 points” that make Kakeru Koumuten’s exterior wall cover method well-received!

Point 1　Super high durability!!

Metal siding offers significantly higher 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 comes with integrated insulation.
Moreover, by installing battens before the metal siding, a ventilation layer is created, significantly enhancing insulation!
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 painting, manufacturer warranties are generally not included.
Metal siding comes with 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!

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 and your preferences for your 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 of interest in 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 of” 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, which can lead to frequent 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, be 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 a concern, you can 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 Costs of Exterior Wall Covering Work

It serves as a cost estimate for performing the exterior wall overlay (cover method) on a building with a total area of 30 tsubo.

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 challenging to find a reliable contractor, such as “where should I request?”
The most important thing when choosing a contractor or obtaining a quote is to always obtain multiple quotes!

For this reason, when requesting exterior wall cover work, let’s check 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, ensure 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 skip creating a ventilation layer and directly apply the siding, moisture cannot escape, leading to mold, corrosion, or potential peeling and lifting of the exterior wall material.
Check if 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, making it hard to compare estimates.
Having clear unit prices and quantities for items like foundation water stops and edge trims will provide peace of mind and help prevent issues.
If there are items of concern not included in the estimate, confirm the reasons 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 presence of warranties and aftercare services

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 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 depending on the contractor and the specifics of the work, but a 5 to 10-year setting is common.

Additionally, some contractors offer after-sales service separate from warranties, 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 conduct after-maintenance and send out annual DM, so if you wish, 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 may vary between contractors, as well as the warranties and after-sales services offered.

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

To request your desired repair contractor at a lower 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 are differences in costs between companies that handle the work in-house and those that outsource it 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 quickly when something happens is one of the reasons why companies that perform the work in-house are recommended!
