If you are looking for an exterior siding contractor in Kakeru Koumuten Co., Ltd. in Hayama, Miura-gun, Kanagawa Prefecture

This will definitely be useful for customers considering exterior siding in Hayama, Miura-gun, so please take a look!

The most important thing to consider when thinking about exterior siding is “multiple estimates”!
Let’s obtain at least three estimates from exterior renovation companies that cover Hayama, Miura-gun!

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 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 cover method are generally lightweight and durable metal siding.

Although the cost is 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 popular?

Here are the “five points” that Kakeru Koumuten Co., Ltd.’s exterior cover method is well-received for!

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 comes with integrated insulation material.
Moreover, by installing furring strips before the metal siding installation to create a ventilation layer, the insulation properties are 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!

Point 5　Enhanced Aesthetics!!

Various designs such as wood grain and tile patterns

Metal siding allows for a finish that resembles a brand-new construction, which is impossible to achieve with exterior painting.
There are various designs available, ranging from simple styles to tile-like and wood grain patterns.
You can choose from a variety of designs that match the atmosphere and your preferences of the 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 should you be aware of when doing exterior wall cover work with metal siding?

Next, we will explain the “three points to be cautious about” when performing exterior wall cover work using 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 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!

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 the most extensive among exterior renovations.
While exterior painting typically takes about 2 to 3 weeks, exterior wall cover work can often take close to 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 costs associated with exterior wall cover work.
It serves as an estimate for the cost of performing the exterior wall cover method on a building with a total 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/㎡~)
Aluminum	40 years or more	Including Tax Approximately 2,500,000 yen (Siding unit price 14,000 yen/㎡~)

The cost will vary depending on the number of painted accessories and windows, as well as the equipment that needs to be removed and reattached.
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 difficult to find a reliable contractor, wondering “where should I request this?”
The most important thing when choosing a contractor or getting a quote is to always obtain multiple quotes!

Therefore, 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 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 the proposed 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 wall and the new siding material using a method called “ventilation method.”
If you skip the ventilation layer and apply it directly, moisture cannot escape, which can lead to mold, corrosion, or peeling and lifting of the siding material.
Check whether the proposed work is appropriate!

・Are the quantities and construction details specified 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.
Having detailed 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, confirm the reasons for their exclusion!

・Check the auxiliary materials being 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, 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 covering work, be sure to check for warranties.

Exterior wall covering work is one of the more expensive renovations, so in addition to the manufacturer’s warranty, 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 by contractor and the specifics of the work, but a 5 to 10-year period is typical.

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 covering work.
We also offer after-maintenance services and send out annual DM, so if desired, inspections can be conducted every year.

3. Obtain estimates from multiple contractors (at least 3 companies)

When requesting exterior wall covering work, be sure to obtain estimates from multiple contractors.

Even for the same repair, 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 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 company performs exterior wall covering work in-house

Companies that handle their own construction versus those that outsource to external companies will have different costs, and there is a higher likelihood of miscommunication and issues arising with external contractors.

Moreover, if problems occur after construction, the response may be slow, or they may not have dealings with the external construction company, leading to further complications.
Being able to respond quickly when issues arise is one of the reasons why companies that perform their own construction are recommended!
