If you are looking for an exterior wall siding contractor in Kakeru Koumuten, Miura City, Kanagawa Prefecture

This will definitely be useful for customers considering exterior wall siding in Miura City, so please take a look!

The most important thing to consider when thinking about exterior wall siding is “multiple estimates”!
Let’s get at least three estimates from exterior renovation companies that cover Miura City!

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

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.

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 higher 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 material.
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 manufacturer warranties such as coating warranties and hole warranties, providing a high level of peace of mind for long-term exterior renovations!

Point 4　Improved Waterproofing!!

With the exterior wall material being double-layered, it significantly prevents rainwater intrusion, thus greatly enhancing waterproofing.
Applying waterproof paper before installation further increases waterproofing effectiveness!

Point 5　Improved Aesthetic Design!!

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 variety of types and designs of metal siding.
If you’re interested in a product from 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 using metal siding for exterior wall cover methods!

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 contractors have little experience, which can lead to frequent issues.
Since there can be a wide variation in estimate costs, to ensure a satisfactory construction, if you are considering the exterior wall cover method with metal siding, be 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 drawbacks.
If noticeable scratches occur and are a concern, you can request repairs from a specialist 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 close to a month.
The long construction period can be a source of stress for residents, making it one of the drawbacks.

About the Costs of Exterior Wall Covering Work

This is a table of estimated costs for exterior wall cover work.
It serves as a cost estimate for 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 cost + Additional painting cost = Total amount
This will be the calculation.

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/㎡~)

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 only a rough estimate, and detailed quotations 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 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 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 that the siding proposed 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 it directly without creating a ventilation layer, moisture cannot escape, which can lead to mold or corrosion, and may cause 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 clear unit prices and quantities for items like base water drainage and edge lengths will provide peace of mind and help prevent issues.
If there are items of concern that are not included in the estimate, check the reason for their exclusion!

・Also 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, the 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 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 types of exterior 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 5 to 10-year period is typical.

Additionally, some contractors offer after-service separate from warranties, 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 services, and we send out annual direct mail, so if desired, inspections can be conducted 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 between contractors, as can the warranties and after-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 supplies!

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 it to external companies, and there is also 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 they may not have a relationship with the external contractor, leading to potential troubles.
Being able to respond quickly when issues arise is one of the reasons why companies that perform work in-house are recommended!
