The most important thing when considering exterior siding is “multiple estimates”!
Let’s obtain at least three estimates from exterior renovation companies that cover Ashigarashimo-gun, Kanagawa!

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 method that overlays a new exterior wall over the existing exterior wall.
It can be applied to various types of exterior walls such as ALC walls, ceramic siding, and mortar walls.
The exterior materials used in the exterior 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 cover method so popular?

Here are the “5 points” that make Kakeru Koumuten’s exterior cover method highly praised!

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, 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, the insulation performance is significantly improved!
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, making it a reassuring choice 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 Aesthetics!!

Various designs such as wood grain and tile patterns

Metal siding allows for a finish that resembles a new construction, which cannot be achieved with exterior painting.
There are various designs available, ranging from simple 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 Industrial“, “Keimyuu“, “Nichiwa“, and “Asahi Tostem“, each offering a variety 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, I will explain the “three points to be cautious about” when using metal siding for exterior wall cover work!

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 wall cover method with metal siding, make 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

This is a reference table for the estimated costs of exterior wall cover work.
It is an estimate for the cost of performing the exterior wall overlay (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 costs + Additional painting costs = Total amount
This will be the total.

Material	Expected Durability (Years)	Cost Assuming 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/㎡~)

Please note that this is only 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 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 requirements?

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, confirm whether the proposed siding meets your original requirements!

・Is it proposed with appropriate construction methods?

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 apply it, 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 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 the lengths of base water cut and edge trim clearly listed with unit prices and quantities will provide reassurance 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 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 guarantees 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 checking for manufacturer warranties, also confirm whether the contractor offers their own 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 setting of 5 to 10 years is common.

Additionally, some contractors offer after-sales service separate from the warranty, 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 we 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 get estimates from multiple contractors.

The cost of the same repair can vary between contractors, and the 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 the best possible 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 contractor 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 miscommunication and other issues with external contractors.

Moreover, if problems arise after the work is completed, the response may be slow, or there may be no dealings with the external contractor, leading to potential troubles.
One of the reasons why companies that perform the work in-house are recommended is that they can respond immediately if something goes wrong!
