If you are looking for an exterior wall siding contractor in Kakeru Koumuten Co., Ltd., Zushi City, Kanagawa Prefecture
Kakeru Koumuten Co., Ltd. is based in Yokohama and has handled many exterior wall cover projects!
The major benefits of exterior wall cover work are the following three points!
“Improved insulation”
“High durability with solid guarantees for peace of mind”
“Beautiful finish like a new building that cannot be achieved with exterior painting”
Exterior wall cover work is gaining attention year by year.
Here, we will also introduce case studies, benefits, precautions, and costs!
This will definitely be useful for customers considering exterior wall siding in Zushi City, so please take a look!
The most important thing when considering exterior wall siding is “getting multiple estimates”!
Let’s obtain at least three estimates from exterior renovation companies that cover Zushi City!
Estimates and consultations are free!
We welcome multiple estimates!
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 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 popular?
We would like to introduce the “five points” that have received positive feedback for Kakeru Koumuten’s exterior wall cover method!
Point 1 Super high durability!!
Metal siding offers an overwhelmingly high expected durability compared to exterior painting.
Made of Galvalume steel, SG 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, 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 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!!
The double-layered exterior material significantly enhances waterproofing by preventing rainwater intrusion.
Applying waterproof paper before installation further increases waterproofing effectiveness!
Point 5 Improved Aesthetic Appeal!!
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 to match the atmosphere and your preferences for 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 doing exterior wall cover work with metal siding?
Next, we will explain the “three points to be cautious about” when performing exterior wall cover work using 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 is often a variation in estimated costs, to ensure a satisfactory construction,
if you are considering the exterior wall cover method with metal siding, be 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 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 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.

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 exterior wall cover work is determined by 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 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/㎡~) |

Please note that this is just a guideline 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 when choosing a contractor or 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.
1. Check the contents and materials of the estimate
2. Confirm the existence of warranties and aftercare services
3. Obtain multiple estimates from several contractors (at least three companies)
4. Confirm whether the contractor performs the exterior wall cover work in-house
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 requirements?
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 meets your original requirements!
・Is it proposed using 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 skip the ventilation layer and apply it directly, moisture cannot escape, which can lead to mold and corrosion, or cause the exterior wall material to peel or lift.
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 foundation water cut and trim 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!
・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 can 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 the manufacturer’s warranty, make sure to check if the company offers its own warranty!
If the contractor has a warranty period, they may offer free repairs within that period.
Warranty periods vary 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 provides a warranty for exterior wall cover work.
We also offer after-maintenance, 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 get estimates from multiple contractors.
The cost of the same repair can vary between contractors, as can warranties and after-service options.
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, which can also lead to communication errors and other issues with external contractors.
Furthermore, if problems arise after the work is completed, responses may be delayed, or there may be no dealings with the external construction company, leading to further complications.
Being able to respond quickly when issues arise is one of the reasons why companies that perform the work in-house are recommended!
