Check for Warranty and After-Service Availability
When choosing a leak repair contractor, let’s confirm the warranty availability.
Leak repairs can recur even after a repair is done, so if you request repairs every time a leak reoccurs, it can lead to significant expenses.
Therefore, if the contractor has a warranty period, there may be cases where repairs can 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 measures or partial repairs often do not come with a leak warranty.
Additionally, some contractors offer after-service separate from the warranty, so make sure to check if the contractor you are considering has warranty andafter-service available.
Kakeru Koumuten Co., Ltd. provides a leak warranty for roof overlay (cover method) and roof replacement work.
Similarly, for exterior walls, a leak warranty is also included for exterior wall cover work, replacement work, and joint sealing work.
As part of our aftercare maintenance, we send out DM every year,
allowing for annual 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 can vary between contractors, and warranties or after-services may differ.
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 rushed, but
first, perform only emergency measures, and if construction is needed, taking your time to consider will lead to a project without regrets!
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 quickly 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, potentially leading to repairs in the wrong areas or suggesting ineffective leak repairs.
Moreover, having to investigate and then request a subcontractor adds unnecessary time and costs.
By having the knowledge and experience to conduct the work in-house, responsible and cost-effective leak repairs can be completed swiftly.
Kakeru Koumuten handles everything from leak investigations to construction in-house!
