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, so if you request repairs every time a leak reoccurs, it can lead to significant expenses.
Therefore, if the contractor offers a warranty period, repairs may be free within that warranty period.
The warranty period varies by contractor and the type of work, but it typically ranges from 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 be sure to check if the contractor you are considering has warranty andafter-service options.
Kakeru Koumuten Co., Ltd. provides a leak warranty for roof overlay work 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 yearly inspections.
Obtain Estimates from Multiple Contractors (At Least 3 Companies)
When requesting roof renovations or leak repairs, be sure to get estimates from multiple contractors.
Even for the same repair, costs and warranty or after-service offerings may vary by contractor.
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, you may feel rushed, but
first perform emergency measures, and if you decide to proceed with repairs, taking your time to consider will help ensure you don’t have regrets about the work!
Kakeru Koumuten Co., Ltd. is happy to assist with emergency leak measures as well!
Confirming Whether We Conduct Rain Leak Investigations and Roof Repairs In-House
Rain leaks can sometimes be easily identified, while in other cases, pinpointing the cause can be quite challenging, requiring knowledge and experience.
If a contractor completely outsources roof repairs and rain leak repairs to subcontractors, they may lack the necessary knowledge and experience, leading to suggestions for repairs in the wrong areas or ineffective rain leak repairs.
Additionally, relying on subcontractors after conducting an investigation incurs extra time and costs.
By having the knowledge and experience to perform the work in-house, we can provide prompt and cost-effective responsible rain leak repairs.
Kakeru Koumuten Co., Ltd. conducts everything from rain leak investigations to construction in-house!
