Check for Warranty and After-Service Availability
When choosing a leak repair contractor, make 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 reoccurs, 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 typically ranges from 1 to 10 years.
Emergency repairs or partial fixes often do not come with a leak warranty.
Additionally, some contractors offer after-service separate from the warranty, so be sure to check if the contractor you are considering has warranty andafter-service options.
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 and replacement work, as well as for joint sealing work.
As part of our after-service, 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, the costs may vary between contractors, and there may be differences in warranties and after-sales services.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired contractor at a lower price, it is essential to obtain estimates from several companies.
If a leak occurs, it’s natural to feel anxious, but
first, perform temporary measures, and if construction is needed, taking your time to consider will lead to a satisfactory outcome!
Kakeru Koumuten is happy to assist with temporary measures for leaks!
Check if the company conducts leak investigations and roof repairs in-house
Leaks can sometimes be easily identified, while in other cases, pinpointing the cause can be 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 can incur additional time and costs.
By having the knowledge and experience to conduct the work in-house, responsible and cost-effective leak repairs can be carried out promptly.
Kakeru Koumuten handles everything from leak investigations to construction in-house!
