If you are looking for an exterior wall siding contractor in Kakeru Koumuten Co., Ltd. in Odawara City, Kanagawa Prefecture

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

The most important thing when considering exterior wall siding is “multiple estimates”!
Let’s obtain at least three estimates from exterior renovation companies that cover Odawara 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 a construction method that overlays a new exterior wall on top of 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.

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 wall cover method so popular?

Here are the “five points” that make Kakeru Koumuten Co., Ltd.’s exterior wall cover method highly regarded!

Point 1　Super high durability!!

Metal siding offers an overwhelmingly higher expected durability compared to exterior painting.
Available in Galvalume steel, SGL steel, and aluminum, metal siding comes in various types, 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 cover method has integrated insulation.
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 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 significantly enhances waterproofing by preventing rainwater intrusion.
Applying waterproof paper before installation further increases waterproofing effectiveness!

Point 5　Improved 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“, “Keimyu“, “Nichihara“, and “Asahi Tostem“, each offering various 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 are the points to be careful about when doing exterior wall cover work with metal siding?

Next, we will explain the “three points to be careful about” when using metal siding for exterior wall cover work!

Point 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 the estimated 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 check the details!

Point 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!

Point 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 nearly a month.
The long construction period can be a source of stress for residents, making it one of the disadvantages.

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 calculation below.
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/㎡~)

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 an estimated amount, and detailed estimates 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 an estimate is to always obtain multiple estimates!

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, such as cost-effective siding and insulation-focused siding, make sure that the siding proposed aligns with your original requirements!

・Is the proposed method of construction 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 do not create a ventilation layer and apply it directly, 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 foundation water cuts and edge trims clearly listed with unit prices and quantities 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!

・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 the recommended fastener.

2. Confirm the existence of guarantees and aftercare maintenance

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 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 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 warranties, 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 conduct after-maintenance and 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 covering work, be sure to get estimates from multiple contractors.

The cost of the same repair can vary between contractors, and there may be differences in warranties and after-sales services.

Additionally, obtaining multiple estimates makes it easier to negotiate prices.

To request your desired repair contractor at a lower 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 ancillary supplies!

4. Confirm whether the contractor performs exterior wall covering work in-house

Companies that handle in-house construction and those that outsource to external companies will have different costs, and there is a higher likelihood of issues such as miscommunication with external contractors.

Additionally, if problems arise after construction, the response may be slow, or there may be no dealings with external construction companies, leading to potential troubles.
Being able to respond immediately when something goes wrong is one of the reasons why companies that perform in-house construction are recommended!
