Check for Warranty and After-Maintenance 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 reoccurs, it can lead to significant expenses.
For this reason, if the contractor offers a warranty period, repairs may be provided 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-services separate from the warranty, so make sure to check if the contractor you are considering has warranties andafter-services.
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-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 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, you may feel rushed, but
first, perform temporary measures, and if construction is needed, taking the time to consider it calmly will lead to a construction process without regrets!
Kakeru Koumuten is happy to assist with emergency leak repairs as well!
Check if the company conducts leak investigations and roof repairs in-house
Leaks can sometimes be easily identified, while in other cases, the source of the leak may be difficult to determine, requiring knowledge and experience for accurate identification.
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 incurs additional time and costs.
By having the knowledge and experience to perform the work in-house, responsible and cost-effective leak repairs can be carried out quickly.
Kakeru Koumuten conducts everything from leak investigations to construction in-house!
