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 Hiratsuka 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 can be applied to 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 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 so popular?

Here are the “five points” that have received praise for Kakeru Koumuten Co., Ltd.’s exterior wall cover method!

Point 1　Super high durability!!

Metal siding offers significantly higher durability compared to exterior painting.
Made of Galvalume steel, SG steel, or 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, which is 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 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 effectively prevents rainwater intrusion, significantly enhancing waterproofing.
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, from simple styles 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“, “Nichiwa“, and “Asahi Tostem“, each offering a 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 to be aware of when performing 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 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 estimated 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 may 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 two to three 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 estimated costs of exterior wall cover work.
It is an estimate for the cost of performing the exterior wall cover method on a building with a floor area of 30 tsubo.

The cost of exterior wall cover work is determined by the calculation below.
Exterior wall area (㎡) × Siding unit price + Equipment removal and installation cost + Additional painting cost = Total amount
This is the formula.

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/㎡~)
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 amount 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 might be challenging to find a reliable contractor, such as “where should I request?”
The most important thing when selecting a contractor or obtaining a quote is to always obtain multiple quotes!

Therefore, when requesting exterior wall cover work, let’s check the following four points.

By checking 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?

Make sure that 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 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 skip creating a ventilation layer and apply it directly, moisture cannot escape, which can lead to mold and corrosion, or even cause peeling and lifting of the exterior wall material.
Check whether the proposed work is appropriate!

・Are the quantities and construction details described 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 clear unit prices and quantities for items like foundation water cut and edge lengths will provide peace of mind and help prevent issues.
If there are items of concern not included in the estimate, confirm the reasons 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, 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 cover work, be sure to check for warranty availability.

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 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 with the contractor you are considering if they provide after-sales service.

Kakeru Koumuten Co., Ltd. always includes a warranty with exterior wall cover work.
We also provide after-maintenance services and 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 get estimates from multiple contractors.

The costs for the same repair can vary between contractors, as can the warranties and after-sales services they offer.

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

To request your desired repair contractor at the best possible price, it is essential to obtain estimates from several companies.
When comparing estimates, consider not only the costs but also the details of the plans, materials, and ancillary 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 it to external companies, and there is also a higher likelihood of miscommunication and other issues with external contractors.

Furthermore, if problems arise after construction, responses may be delayed, or the company may not have dealings with the external contractor, leading to potential troubles.
Being able to respond immediately in case of issues is one of the reasons why companies that perform the work in-house are recommended!
