The most important thing to consider when thinking about exterior siding is “getting multiple estimates”!
Let’s obtain at least three estimates from exterior renovation companies that cover Akishima 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 a construction process that overlays a new exterior wall on top of the existing 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.

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 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 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 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 performance!

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 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 that match the atmosphere and your preferences for your building!
Major manufacturers include “Aiji Industrial“, “Keimyuu“, “Nichiwa“, and “Asahi Tostem“, each offering a range of types and designs of metal siding.
If you find a product you are interested in while looking at the catalog, you can also request cut samples!

What to be cautious about with metal siding exterior cover work?

Next, I will explain the “three points to be cautious about” when performing exterior cover work with 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 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 cover method with metal siding, make sure to get 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 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 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 guideline table for the estimated costs of exterior wall cover work.
It is an estimate for the cost of performing the exterior wall cover method on a building with a floor area of 30 tsubo.

The cost of the exterior wall cover work will be estimated based on 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	Including Tax Approximately 2,000,000 yen (Siding unit price 11,000 yen/m²~)
SGL Steel	35 to 40	Including Tax Approximately 2,200,000 yen (Siding unit price 12,500 yen/m²~)
Aluminum	40 years or more	Including Tax Approximately 2,500,000 yen (Siding unit price 14,000 yen/m²~)

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.
Please note that this is just a rough estimate, and detailed quotes 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 challenging to find a reputable contractor, such as “where should I request the work?”
The most important thing when selecting 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 focused on cost or insulation, confirm whether the siding proposed aligns with your original needs!

・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 attach the siding, moisture cannot escape, leading to mold or corrosion, and may result in 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 estimate states something vague like “exterior wall cover work 1 set,” it becomes difficult to understand the construction method and what the costs are for, making it hard to compare estimates.
Having clear descriptions of unit prices and quantities for items like foundation water cuts and edge trims will provide peace of mind and help prevent issues.
If there are items of concern not included in the estimate, check the reason for their exclusion!

・Check the auxiliary materials to be used!

Check the types of “furring strips“, “siding fasteners“, and “waterproof paper“, not just the siding itself, but also the types of detailed auxiliary materials!
For example, the 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 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 nature 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 includes a warranty with exterior wall cover work.
We also provide after-maintenance services and send out annual direct mail, 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 obtain 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 cost, 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 contractor 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 issues such as miscommunication with external contractors.

Furthermore, if problems arise after construction, responses may be delayed, or there may be no dealings with external construction companies, 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!
