Check for Warranty and Aftercare 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 you choose a contractor that offers a warranty period, you may be able to get repairs 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 repairs or partial fixes often do not come with a leak warranty.
Additionally, some contractors offer after-sales service separate from their warranty, 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 roof overlay work and roof replacement work.
Similarly, for exterior walls, a leak warranty is included for exterior wall overlay work, replacement work, and joint sealing work.
As part of our aftercare maintenance, we send out annual DM, allowing for inspections every year.
Obtain estimates from multiple contractors (at least 3)
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 the warranties and after-sales services may differ as well.
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 temporary measures, and if you proceed with construction, taking your time to consider will help ensure you don’t have regrets about the work!
Kakeru Koumuten is happy to assist with emergency 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 be difficult to pinpoint the cause, requiring knowledge and experience.
Contractors that completely outsource roof repairs and leak repairs may lack the necessary knowledge and experience, leading to proposals for repairs in the wrong areas or 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 perform the work in-house, we can provide prompt and cost-effective responsible leak repairs.
