The most important thing when considering exterior wall siding is “getting multiple estimates”!
Let’s obtain at least three estimates from exterior remodeling companies that cover Atsugi City!

Estimates and consultations are free!
We welcome multiple estimates!

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 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 cover method are generally lightweight and durable metal siding.

Although the cost is higher compared to exterior painting, it is a method of exterior remodeling that has various benefits and is gaining attention year by year.

Why is the exterior wall cover method so popular?

We would like to introduce the “five points” that have received great feedback for Kakeru Koumuten’s exterior wall cover method!

Point 1　Super high durability!!

Metal siding offers an overwhelmingly high 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, which is one of its strengths!
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 comes with integrated insulation.
Moreover, by installing battens before the metal siding installation to create a ventilation layer, the 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 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 and your preferences for your 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 of interest in the catalog, you can also request cut samples!

What are the points to be careful about when doing exterior wall cover work with metal siding?

Next, we will explain the “three points to be careful about” when using metal siding for exterior wall cover methods!

Point 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 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 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 if 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 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 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 estimated costs of exterior wall cover work.
It represents the estimated costs for a 30-tsubo exterior wall cover method.

The costs for exterior wall cover work are determined by the following calculation.
Exterior wall area (㎡) × Siding unit price + Equipment removal and installation costs + Additional painting costs = Total amount
This is how it is calculated.

Material	Expected Durability (Years)	Cost Assuming a building area of 30 tsubo (150㎡)
Galvalume Steel	30 to 35	Including Tax Approximately 2,000,000 yen (Siding unit price 11,000 yen/㎡~)
SGL Steel	35 to 40	Including Tax Approximately 2,200,000 yen (Siding unit price 12,500 yen/㎡~)
Aluminum	40 or more	Including Tax Approximately 2,500,000 yen (Siding unit price 14,000 yen/㎡~)

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.
This is just a rough estimate, so please feel free to contact us for a detailed estimate, which is completely free of charge.

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 work?”
The most important thing when selecting a contractor or obtaining an estimate is to always obtain multiple estimates!

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 the proposed materials meet your requirements, such as durability and insulation!
Since there are various types of metal siding, such as cost-effective siding and insulation-focused siding, make sure the 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 apply the new siding directly without a ventilation layer, moisture cannot escape, which may lead to mold, corrosion, or detachment of the exterior wall material.
Check whether the proposed work is appropriate!

・Are the quantities and construction details clearly specified?

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 foundation water drainage and trim lengths will provide peace of mind and help prevent issues.
If there are items of concern that are not included in the estimate, be sure to ask why they are not included!

・Check the auxiliary materials to be used!

Check the types of auxiliary materials, such as “types of battens,” “siding fasteners,” and “types of waterproof paper,” not just the siding itself!
For example, siding fasteners are screws, and the overall cost can 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 renovations, so in addition to the manufacturer’s warranty, also check for the presence of a company warranty!
If the contractor has a warranty period, they may offer free repairs within that period.

The warranty period varies by 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 the warranty, so be sure to confirm 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 we send out annual DM, 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 obtain estimates from multiple contractors.

The cost of the same repair can vary by contractor, and warranties and after-sales services may differ as well.

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 in-house construction and those that outsource to external companies, and there is a higher likelihood of miscommunication and issues arising with external contractors.

Additionally, if problems occur 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 immediately when something happens is one of the reasons why companies that perform in-house construction are recommended!
