Check for Warranty and Aftercare Services
When choosing a leak repair contractor, let’s confirm the 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, repairs may be done for free within that warranty period.
The warranty period varies by contractor and the nature of the work, but it is generally set between 1 to 10 years.
Emergency measures or partial repairs often do not come with a leak warranty.
Additionally, some contractors offer after-sales service separate from their warranty, so it’s important to check if the contractor you are considering has warranties andafter-sales service.
Kakeru Koumuten Co., Ltd. provides a leak warranty for both roof overlay and roof replacement work.
Similarly, for exterior walls, a leak warranty is included for exterior wall overlay and replacement work as well as for 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 obtain estimates from multiple contractors.
Even for the same repair work, costs may vary between contractors, as well as warranties and after-sales services.
Additionally, obtaining multiple estimates makes price negotiations easier.
To request your desired repair contractor at a lower price, it is essential to obtain estimates from several contractors.
If a leak occurs, it’s natural to feel anxious, but
first, perform emergency measures, and if you proceed with repairs, taking your time to consider will lead to a satisfactory outcome!
Kakeru Koumuten is happy to assist with emergency leak measures only!
Check if the company conducts leak investigations and roof repairs in-house
Leaks can sometimes be easily pinpointed, while in other cases, identifying the source of the leak can be quite challenging, 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 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.
