Check for Warranty and Aftercare Services
When choosing a leak repair contractor, make sure to check for warranties.
Leak repairs can recur even after being fixed once, so if you have to request repairs every time a leak reappears, it can lead to significant expenses.
For this reason, if you choose a contractor that offers a warranty period, repairs may be done for free within that warranty period.
Warranty periods vary by contractor and type of work, but typically range from 1 to 10 years.
Emergency repairs or partial fixes often do not come with a leak warranty.
Additionally, some contractors offer after-sales services separate from their warranties, so be sure to check if the contractor you are consideringhas warranties and after-sales 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 for joint sealing work.
As part of our aftercare, we send out annual direct mail, allowing for inspections every year.
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, the costs can vary between contractors, as well as the warranties and after-sales services offered.
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 if construction is needed, taking your time to consider will lead to a satisfactory outcome!
Kakeru Koumuten is happy to assist with emergency leak measures as well!
Check if 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 proposals for repairs in the wrong areas or unnecessary 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.
Kakeru Koumuten conducts leak investigations and construction in-house!
