The most important thing when considering exterior siding is “multiple estimates”!
Let’s get at least three estimates from exterior renovation companies that cover Komae City!

Estimates and consultations are free!
Multiple estimates are very welcome!

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 on top of the existing exterior.
It can be applied to various exteriors such as ALC walls, ceramic siding, and mortar exteriors.
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 exteriors that has various benefits and is gaining attention year by year.

Why is the exterior cover method so popular?

We would like to introduce the “five points” that have received positive feedback for Kakeru Koumuten’s exterior 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, 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, 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 wall painting, manufacturer warranties are generally not included.
Metal siding comes with solid manufacturer warranties for paint film and perforation, providing a high sense of security for long-term exterior renovations!

Point 4　Improved Waterproofing!!

With the exterior wall material being double-layered, it significantly enhances waterproofing by preventing rainwater intrusion.
Applying waterproof paper before installation further increases waterproofing effectiveness!

Point 5　Improved Aesthetic Appeal!!

Various designs such as wood grain and tile patterns

Metal siding allows for a finish that resembles new construction, which is impossible to achieve 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 of the building and your preferences!
Major manufacturers include “Aiji Industry“, “Keimyuu“, “Nichihara“, and “Asahi Tostem“, each offering a wide range 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 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 using metal siding for exterior wall cover methods!

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 can be a lot of 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 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

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 Costs of Exterior Wall Covering Work

This is a reference table for the estimated costs of exterior wall cover work.
It is based on the cost estimate for a 30-tsubo exterior wall cover method.

The cost of exterior wall cover work is determined by the following calculation:
Exterior wall area (㎡) × Siding unit price + Equipment removal and installation cost + Additional painting cost = Total amount
This will be the total.

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

The amount will vary depending on the number of painted accessories and windows, as well as the equipment to be removed and installed.
Please note that this is just a guideline amount, and detailed estimates are 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 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 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 siding proposed aligns with your original requirements!

・Is the proposed construction 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 it directly without creating a ventilation layer, moisture cannot escape, leading to mold or corrosion, and may result in peeling or lifting of the exterior wall material.
Check whether the proposed construction 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 drainage and edge trim 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 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 seem cheaper at first glance, stainless steel is resistant to rust and is the recommended fastener.

2. Confirm the presence of guarantees and aftercare

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, make 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-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 offer 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 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 several contractors.
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 to external companies, and there is also a higher likelihood of miscommunication and issues arising with external contractors.

Moreover, 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 happens is one of the reasons why companies that perform the work in-house are recommended!
