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

This will definitely be helpful for customers considering exterior siding in Hadano City, so please take a look!

The most important thing to consider when looking into exterior siding is “comparing estimates”!
Let’s obtain at least three estimates from exterior renovation companies that cover Hadano City!

Estimates and consultations are free!
Comparing estimates is highly welcomed!

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 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.

While the costs are 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 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 significantly higher durability compared to exterior painting.
Galvalume steel, SGL steel, and aluminum are 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 another advantage!
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, 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 peace of mind for long-term exterior renovations!

Point 4　Improved Waterproofing!!

With the exterior material being double-layered, waterproofing is significantly enhanced to prevent rainwater intrusion.
Applying waterproof paper before installation further increases waterproofing effectiveness!

Point 5　Enhanced Aesthetics!!

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 to tile 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“, “Nichihara“, and “Asahi Tostem“, each offering various 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!

Caution 1　Few contractors can perform the installation

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 estimation 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 concerning, 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, the construction period for exterior wall cover work can often approach one month.
The long construction period can be a source of stress for residents, making it one of the disadvantages.

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 determined by the following calculation:
Exterior wall area (㎡) × Siding unit price + Equipment removal and installation costs + Additional painting costs = Total amount
This will be the total.

Galvalume Steel	30 to 35	Including Tax Approximately 2,000,000 yen (Siding price per ㎡ starts from 11,000 yen)

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 estimates is to always obtain multiple estimates!

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, confirm whether the siding proposed aligns with your original requirements!

・Is it proposed with appropriate construction methods?

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 a ventilation layer, moisture cannot escape, which can lead 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 detailed descriptions of the lengths of foundation water cuts and trim edges, along with unit prices and quantities, will provide reassurance and help prevent issues.
If there are items of concern that are not included in the estimate, confirm the reasons for their exclusion!

・Also check the auxiliary materials to be used!

Check not only the main siding 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 the recommended fastener.

2. Confirm the existence of guarantees and aftercare maintenance

When choosing an exterior wall cover contractor, 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, 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-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 includes a warranty with exterior wall cover work.
We also provide after-maintenance, and we send out annual direct mail, so if desired, 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.

Even for the same repair, the costs may vary between contractors, as well as the warranties and after-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 supplies!

4. Confirm whether the company performs exterior wall cover work in-house

There are cost differences between companies that handle the work in-house and those that outsource to external companies, and there is a higher likelihood of miscommunication and issues with external contractors.

Moreover, if problems arise after construction, responses may be delayed, or there may be no dealings with the external construction company, leading to potential troubles.
Being able to respond immediately when issues arise is one of the reasons why companies that perform the work in-house are recommended!
