Check for Warranty and Aftercare Services
When choosing a leak repair contractor, it is important to check for warranties.
Leak repairs can recur even after being fixed once, so if you have to request repairs every time a leak happens, it can lead to significant expenses.
Therefore, if the contractor offers a warranty period, repairs may be done for free within that warranty period.
The warranty period varies depending on the contractor and the type of work, but it is generally set between 1 to 10 years.
Emergency repairs or partial repairs often do not come with a leak warranty.
Additionally, some contractors offer after-sales service separate from the warranty, so it’s important to check if the contractor you are considering has warranties and after-sales service.
Kakeru Koumuten Co., Ltd. provides a leak warranty for all roof overlay and roof replacement work.
Similarly, for exterior walls, a leak warranty is included for exterior wall overlay work, replacement work, and joint sealing work.
As part of our aftercare maintenance, 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, the costs and warranties or after-sales services may vary between contractors.
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 rushed, but
first, perform emergency measures, and if you proceed with repairs, taking your time to consider will lead to a satisfactory outcome!
Kakeru Koumuten Co., Ltd. is happy to assist with emergency leak repairs!
Check if the company conducts leak investigations and roof repairs in-house
Leaks can sometimes be quickly identified, while in other cases, it may take time to pinpoint the source, requiring knowledge and experience.
Contractors that completely outsource roof repairs and leak repairs to subcontractors may lack the necessary knowledge and experience, leading to repairs in the wrong areas or suggesting ineffective leak repairs.
Moreover, having to investigate and then request a subcontractor adds extra time and costs.
By having the knowledge and experience to conduct the work in-house, we can provide prompt and cost-effective responsible leak repairs.
Kakeru Koumuten Co., Ltd. conducts everything from leak investigations to construction in-house!
