Check for Warranty and After-Service
When choosing a leak repair contractor, let’s confirm the warranty availability.
Leak repairs can recur even after one repair, so if you have to request repairs every time a leak reoccurs, it can lead to significant expenses.
For this reason, if the contractor has a warranty period, repairs may be done for free within that warranty period.
The warranty period varies by contractor and type of work, but it is generally set between 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.
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 joint sealing work.
As part of our after-service, we send out annual DM, allowing for inspections every year.
Obtain estimates from multiple contractors (at least 3 companies)
When requesting roof renovations or leak repairs, be sure to obtain estimates from multiple contractors.
The repair costs may vary between contractors even for the same repair work, 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, you may feel rushed, but
first perform temporary measures, and if construction is needed, taking your time to consider will lead to a construction that you won’t regret!
Kakeru Koumuten is happy to respond to requests for 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, it may take time to pinpoint the cause, 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 unnecessary 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, responsible and cost-effective leak repairs can be performed quickly.
Kakeru Koumuten conducts everything from leak investigations to construction in-house!
