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

Estimates and consultations are free!
We welcome multiple estimates!

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 process that overlays a new exterior on top of the existing exterior.
It can be applied to various types of exteriors such as ALC walls, ceramic siding, and mortar exteriors.
The materials used for 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 so popular?

Here are the “five points” that make Kakeru Koumuten’s exterior cover method highly regarded!

Point 1　Super high durability!!

Metal siding offers an overwhelmingly high expected 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, 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 cover method has integrated insulation material.
Moreover, by installing battens before the metal siding installation to create a ventilation layer, the insulation performance is significantly improved!
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, making it a reassuring choice for long-term exterior renovations!

Point 4　Improved Waterproofing!!

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

Point 5　Improved Aesthetics!!

Various designs such as wood grain and tile patterns

Metal siding allows for a finish that resembles a brand-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 of the building!
Major manufacturers include “Aiji Industrial“, “Keimyuu“, “Nichihara“, 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 to be cautious about with metal siding exterior cover work?

Next, we will explain the “three points of caution” when performing exterior cover work with 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 significant variations in estimate costs, to ensure a satisfactory construction, if you are considering the exterior 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 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 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.

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 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 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, confirm whether the proposed siding meets your original requirements!

・Is it proposed with the appropriate construction method?

When performing exterior wall cover work, it is necessary to establish 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, leading to mold or corrosion, and it 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 the lengths of base water cut and trim edges clearly listed with unit prices and quantities will provide reassurance and help prevent issues.
If there are items of concern 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 a recommended fastener.

2. Confirm the existence of guarantees and aftercare

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 the manufacturer’s warranty, also confirm whether the company offers its own warranty!
If the contractor has a warranty period, they may offer free repairs within that period.

The warranty period varies depending on the contractor and the scope of 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 includes a warranty with exterior wall cover work.
We also provide after-maintenance services and send out annual DM, so if you wish, you can have inspections 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-sales services they offer.

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

To request your desired repair contractor at a lower 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 auxiliary materials!

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

There are differences in costs between companies that handle in-house construction and those that outsource to external companies, and issues such as miscommunication with external contractors can easily arise.

Additionally, if problems occur after construction, responses may be slow, or there may be no dealings with the external construction company, leading to further complications.
Being able to respond immediately in case of issues is one of the reasons why companies that perform in-house construction are recommended!
