Examples of leak repairs by Kakeru Koumuten Co., Ltd. in Nishitokyo City
Construction Location
Temporary Scaffolding Installation
A resident of Nishi-Tokyo City, Tokyo contacted us stating, “During an inspection by the house manufacturer, I was informed that there are numerous cracks and breaks in the roofing materials. I requested a quote for the roof overlay method, but the cost was high. I would like to request estimates from about three companies.”
〇Roof Overlay (Cover Method)
・Existing roofing material: Colonial NEO
・Materials used for roof overlay method: Aijii Industry / Super Galtect (Color: Moss Green)
・Roofing sheet: Tajima Roofing / Tadi Self Cover
Our Proposal
Since the customer desired a highly durable roofing material, we proposed the Super Galtect, which is our most popular and highly durable option!
Check for Warranty and Aftercare Services
When choosing a leak repair contractor, be sure to check for warranty availability.
Leak repairs can recur even after being fixed once, so if you have to request repairs every time a leak reappears, it can lead to significant expenses.
For this reason, if you choose a contractor that offers a warranty period, you may be able to get repairs done for free within that warranty period.
Warranty periods vary by contractor and the nature of the work, but they typically range from 1 to 10 years.
Emergency repairs or partial fixes often do not come with a leak warranty.
Additionally, some contractors offer after-sales services separate from warranties, so it’s important to check if the contractor you are considering has warranties and after-sales services.
Kakeru Koumuten Co., Ltd. provides a leak warranty for both roof overlay (cover method) and roof replacement work.
Similarly, for exterior walls, a leak warranty is included for exterior wall cover work, replacement work, and joint sealing work.
As part of our aftercare, we send out annual direct mail, allowing for yearly inspections.
Obtain estimates from multiple contractors (at least 3 companies)
When requesting roof renovations or leak repairs, be sure to get estimates from multiple contractors.
Even for the same repair work, costs can vary between contractors, as can 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.
If a leak occurs, it’s natural to feel anxious, but
first, perform emergency measures, and if construction is needed, taking the time to consider your options will lead to a satisfactory outcome!
Kakeru Koumuten is happy to assist with emergency leak measures as well!
Check if the company conducts leak investigations and roof repairs in-house
Leaks can sometimes be easily identified, while in other cases, it may take time to pinpoint the cause, requiring knowledge and experience.
Contractors that completely outsource roof repairs and leak repairs may lack the necessary knowledge and experience, leading to proposals for repairs in the wrong areas or unnecessary leak repairs.
Moreover, relying on subcontractors after an investigation incurs additional time and costs.
By having the knowledge and experience to conduct the work in-house, we can provide prompt and cost-effective leak repairs with accountability.
Kakeru Koumuten conducts leak investigations and construction in-house!
