Reasons why Kakeru Koumuten is chosen for waterproofing work in Oume City, Tokyo
Regarding the reasons why our company is entrusted with waterproofing work by customers in Oume City, Tokyo,
“Our strengths in waterproofing work that cannot be imitated by other companies”
have received high praise from many customers.
In waterproofing work in Oume City, Tokyo,
we have absolute confidence in “cost,” “quality,” and “plans,” so
we would appreciate it if you could compare our estimates with those of other companies.
Because we are confident, we welcome competitive estimates!
1．Specialized equipment for exterior renovations
At Kakeru Koumuten Co., Ltd., we have organized the following warehouses and material storage areas to provide more affordable and faster exterior renovations such as waterproofing work.
We have established five bases centered around Aoba-ku, Yokohama for material storage and showrooms.
In-house Ownership of Scaffolding Materials
We own the scaffolding materials necessary for temporary scaffolding required for waterproofing work, allowing us to assemble temporary scaffolding in-house.
By not outsourcing scaffolding work and performing it with our own scaffolding team, we can also reduce the costs associated with scaffolding construction.
Since everything is done in-house, we can significantly reduce costs by shortening the construction period!
We have approximately enough scaffolding materials for 50 single-family homes!
Storage of Materials in Our Large In-house Warehouse
We store roofing materials and waterproofing components.
By ordering a large quantity of materials at once, we can procure materials at a lower cost!
Additionally, we always have waterproofing components in stock, allowing us to respond quickly to emergency waterproofing work!
In-house waste separation
In waterproofing work, various waste materials are generated.
Most contractors dispose of them all together, but by sorting and recycling waste materials, significant cost reductions in waste disposal can be achieved.
Exterior Renovation Dedicated Showroom
In our showroom, not only can you have meetings, but you can also
directly check the actual structure and colors.
2．Complete In-House Construction
One of Kakeru Koumuten’s major strengths is complete in-house construction.
From inquiry to completion, everything is handled by Kakeru Koumuten Co., Ltd., allowing us to keep costs down while providing high-quality waterproofing work.
Additionally, one representative will assist you from the estimate to the completion of the project.
Since the same person will handle sales and construction management, smooth communication is possible.
We are confident in our construction plans and costs, so we welcome competitive estimates!
3. Various Permits and Skilled Workers
We have obtained permits for construction work and industrial waste collection and transportation!
We also have qualified personnel on staff, and we are confident in our construction techniques.
We are capable of handling large-scale waterproofing projects, such as those for factories!
4. Warranty and Aftercare
Waterproofing work comes with a guarantee!
Depending on the type of waterproofing work, we provide a 5 to 10-year leak warranty.
If you have any questions about the warranty, please click on the image above!
In the unlikely event that leaks are not resolved after the waterproofing work, we will take responsibility and respond accordingly!
Additionally, aftercare maintenance is available annually, and we will send you a DM reminder for aftercare maintenance each year.
During aftercare maintenance, we will check the entire waterproofing system and assess the condition of any deterioration.
5. Flexible and Prompt Response
Our company is equipped to handle various troubles and situations.
If we cannot access the rooftop for waterproofing checks, we will utilize drones to assess the condition.
During leak investigations, we can also conduct inspections using thermal imaging cameras.
We will respond according to your wishes.
We also accept emergency measures for sudden leaks!
Since our sales and construction management are not separated, one dedicated representative will handle everything from the estimate to the completion of the work!
Changing representatives frequently can lead to miscommunication regarding the details and precautions of the work, which could cause problems, so our company has a system in place to keep the same representative throughout the process.
6. Human Resource Development
To enhance our skills, we create models of various buildings and conduct practical training.
We regularly provide technical training to ensure that all staff can handle various types of buildings.

| Inquiry Details |
| We have received the following inquiries from our customer. ・There are wrinkles and bulges in the waterproof sheet on the rooftop, so we are worried about leaks. ・We would like an estimate for a complete waterproof renovation, not just partial repairs or a top coat. ・We learned that urethane waterproofing has high waterproofing properties, so we would like an estimate for urethane waterproofing. ・Since this is our first waterproofing project, we would like to compare estimates. |
Our Proposal
Since you expressed a desire to renovate using a long-lasting method rather than protective agents like top coats, we proposed a complete “urethane waterproofing project” for the rooftop.
If urethane waterproofing is applied using the adhesion method, air rising from the building can cause bulges in the waterproof layer, so we proposed the “urethane waterproofing ventilation buffer method.”
The ventilation buffer method involves applying a ventilation buffer sheet over the entire area before installing the urethane waterproofing.
By applying the ventilation buffer sheet first, air rising from the building is suppressed by the ventilation sheet and expelled through the “ventilation tube.”
This method can prevent the most common problem with waterproofing, which is bulging of the waterproof layer!
After explaining the materials and methods, you entrusted the project to us among the four estimates you received!
Timing for Waterproofing Work
Leaks Have Already Occurred
If leaks have already occurred, it is necessary to address the issue promptly before the damage spreads.
If left unattended, it can adversely affect the interior and underlying structures, so it is essential to stop the leaks quickly.
Bulges or Cracks in the Waterproof Layer
If the waterproof area has cracks, it can lead to rainwater intrusion.
If the waterproof layer is bulging, it indicates that moisture is accumulating within the layer.
Bulging can lead to cracks, which can result in leaks, so early detection and action are necessary.
Moss or Mold Growth
Moisture or rainwater accumulation can lead to the growth of moss or mold.
This can be caused by poor drainage or sinking of the waterproof layer due to aging.
Exceeding the Durability Period
Generally, the durability period for waterproofing work is 10 to 20 years.
Of course, the durability can vary depending on the construction method and materials, but for some types of waterproofing, it is recommended to apply only the surface protective agent (top coat) approximately every 8 years (such as urethane waterproofing or FRP waterproofing).
We recommend regular inspections starting from 5 years after construction.
Understanding the types of waterproofing and performing appropriate maintenance is essential.
If you are unsure about the type of waterproofing, please send us a photo via email or LINE, and we will help you determine it!
Types of Waterproofing Work
1. Urethane Waterproofing
Urethane waterproofing is a method that involves applying liquid polyurethane resin to the waterproofing surface.
Before curing, it is in liquid form, allowing it to be applied to complex shapes, and unlike sheet waterproofing, it can be applied without seams.
It can be widely used on balconies and rooftops.
For more details on the advantages, disadvantages, and maintenance methods of urethane waterproofing, please refer to the article below.

2. Rubber Sheet Waterproofing
Rubber sheet waterproofing involves adhering synthetic rubber sheets to the surface to prevent water intrusion.
This type of waterproofing is commonly used on large areas such as rooftops.
Compared to urethane waterproofing, it has the advantage of faster installation since there is no waiting for drying, but it is not suitable for complex surfaces.
For more details on the advantages, disadvantages, and maintenance methods of rubber sheet waterproofing, please refer to the article below.

3. PVC Sheet Waterproofing
PVC sheet waterproofing is a waterproof sheet made of polyvinyl chloride, which, like rubber sheet waterproofing, is applied to the surface to prevent water intrusion.
Similar to rubber sheets, it is not suitable for complex shapes. Although the cost is higher than rubber sheets and urethane waterproofing, its long durability is a significant advantage.
For more details on the advantages and disadvantages of PVC sheet waterproofing and maintenance methods, please refer to the article below.

4. Long Sheet Waterproofing
Long sheet waterproofing, officially known as “anti-slip vinyl floor sheet,” is commonly applied in shared areas of apartments and staircases where people walk.
As the name suggests, it is slip-resistant and has high durability and abrasion resistance, making it suitable for walking areas.
Additionally, it comes in various designs, excelling in aesthetic appeal.
However, it tends to be more expensive, and since it does not overlap seams like rubber sheets or PVC sheets, it may give a slightly lower impression of waterproofing capability.
It is rarely used in areas like rooftops of apartments where people do not frequently enter.
For more details on the advantages and disadvantages of long sheet waterproofing and maintenance methods, please refer to the article below.

5. FRP Waterproofing
FRP waterproofing involves creating a waterproof layer by solidifying glass mat with epoxy resin to prevent rainwater intrusion.
It is commonly applied on single-family home balconies, with an overwhelmingly short construction period, often completed in as little as one day.
Due to its lightweight and low cost, it is estimated that about 80% of single-family home balconies use FRP waterproofing.
However, it is not suitable for installation on large surface areas, making it less appropriate for rooftop applications.
For more details on the advantages and disadvantages of FRP waterproofing and maintenance methods, please refer to the article below.

6. Asphalt Waterproofing
Asphalt waterproofing is a waterproof sheet that has asphalt permeated into synthetic fiber non-woven fabric.
The waterproofing shown in the photo is a method where asphalt waterproofing is pressed down with cinder concrete.
This waterproofing is used for large buildings such as rooftops of schools and commercial facilities.
There are various methods of asphalt waterproofing, each with its own advantages and disadvantages, but a significant advantage is its high durability.
For detailed explanations of the advantages, disadvantages, and maintenance methods of asphalt waterproofing, please refer to the article below.

How to Choose a Waterproofing Contractor
There are many waterproofing contractors available in Ome City, Tokyo.
Among the numerous contractors, I believe many people feel “I don’t know who to ask for help…”.
Choosing a contractor for the first time can be challenging, so I will explain 5 points to be careful about when requesting waterproofing work.
● Have extensive experience in waterproofing work
● Check for aftercare and warranty availability
● Obtain estimates from multiple contractors (at least 3 companies)
● Confirm whether they perform waterproofing work in-house
● Carefully review the details of the waterproofing estimate, including the process and materials used
By confirming the above 5 points, you will be able to choose a reliable contractor.
Check if they have extensive experience in waterproofing work
About 10-20% of waterproofing work troubles are caused by construction defects during the installation.
To prevent troubles, it is important to hire a reliable contractor with experience!
You need to refer to the contractor’s website for their construction achievements and reviews to make a judgment.
Some contractors showcase their achievements on social media platforms like Instagram, so checking those can also be effective!
It is also effective to look at waterproofing companies on review sites for reference!
A particularly recommended review site is “Google”.
Since contractors cannot arbitrarily delete low ratings, it is a trustworthy source of reviews.
If there are many negative reviews or no reviews at all, it may be wise to refrain from making a request.
Check if there is aftercare maintenance and construction warranty
In case any construction defects or issues occur after the work is done, let’s confirm if they provide a “construction warranty“!
Contractors who offer warranties are usually confident in their work, making them more trustworthy!
If waterproofing work is done, make sure to take photos of the unseen areas during the process for confirmation!
Check for leaks during rainy weather after the waterproofing work, and if there are any issues, contact the contractor immediately as it will facilitate smooth communication shortly after the work is completed!
Also, to ensure early detection of any issues that may arise, confirm if they will conduct thorough aftercare maintenance!
Since non-specialized contractors may not notice signs of problems or troubles, having a specialized contractor perform regular aftercare maintenance can help prevent issues before they occur!
Our company sends out aftercare maintenance DM every year, so if you wish, annual aftercare maintenance is possible!
Obtain estimates from multiple contractors for waterproofing work (at least 3 companies)
When requesting waterproofing work, be sure to obtain estimates from multiple contractors.
We recommend obtaining estimates from at least 3 companies.
Even for the same waterproofing work, costs may vary between contractors, and warranties and after-services may differ as well.
Additionally, obtaining multiple estimates makes it easier to negotiate prices. To request at the lowest possible cost, obtaining estimates from multiple contractors is essential.
When comparing estimates, check not only the costs but also the “types of materials used” and “construction methods” to compare the finer details!
Check if they perform waterproofing work in-house
Confirm whether they perform waterproofing work in-house!
If a sales company investigates and then requests a subcontractor, it will incur additional time and costs.
Moreover, there may be cases where your requests are not communicated 100% to the subcontractor, leading to troubles.
By having one company handle everything from sales to construction, it enables responsible waterproofing work that is quick and cost-effective. Kakeru Koumuten handles everything from on-site surveys to actual construction in-house!
Furthermore, if any leaks or troubles occur, a company that employs its own craftsmen can respond to and resolve issues quickly!
Carefully Check the Details of Waterproofing Estimates, Processes, and Materials
Even for the same waterproofing work, there are various types such as “methods,” “materials,” and “processes,” and it is necessary to carry out the work using the most suitable method and materials depending on the construction site and existing substrate.
For example, even with the same urethane waterproofing, there are different types of processes such as “adhesion method” and “ventilated buffer method,” and there are various types of urethane waterproofing materials, including “high-strength specifications,” “heat-insulating specifications,” and “anti-slip specifications.” Therefore, it is essential to confirm whether the construction content is appropriate for the location!
It is important to check in detail whether “is it the appropriate method for the substrate?” and “is it the appropriate material?” rather than judging solely by cost.
So, if the materials used are only “urethane waterproofing materials,” let’s confirm the product name and check what kind of materials they are!
