Check for Warranty and Aftercare Services
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 the contractor 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 services separate from warranties, so be sure to check if the contractor you are considering has warranties andafter-sales services.
Kakeru Koumuten Co., Ltd. provides a leak warranty for both roof overlay (cover method) and roof replacement work.
Similarly, for exterior walls, a leak warranty is included for exterior wall cover work, replacement work, and joint sealing work.
As part of our aftercare maintenance, we send out annual DM, 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, as well as the warranties and after-sales services.
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 anxious, but
first, perform temporary measures, and when considering construction, taking your time to think it through will help ensure you won’t have regrets!
Kakeru Koumuten Co., Ltd. is happy to assist with emergency leak measures!
Confirm whether 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 source, requiring knowledge and experience.
Contractors that completely outsource roof repairs and leak repairs may lack the necessary knowledge and experience, leading to repairs in the wrong areas or suggestions for 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, we can provide prompt and cost-effective responsible leak repairs.
Kakeru Koumuten Co., Ltd. conducts everything from leak investigations to construction in-house!
