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, so if you need to request repairs every time a leak reoccurs, it can lead to significant expenses.
For this reason, contractors that offer a warranty may provide free repairs within the warranty period.
The warranty period varies by contractor and type of work, but it typically ranges from 1 to 10 years.
Emergency repairs or partial fixes often do not come with a leak warranty.
Additionally, some contractors offer aftercare services separate from warranties, so be sure to check if the contractor you are considering has warranties andaftercare services.
Kakeru Koumuten Co., Ltd. provides a leak warranty for both roof overlay and roof replacement work.
Similarly, exterior wall cover work, replacement work, and joint sealing work also come with a leak warranty.
As part of our aftercare, we send out annual DM, allowing for yearly inspections.
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, costs may vary between contractors, and warranties and after-sales services may differ as well.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your preferred contractor at a lower price, it is essential to get estimates from several companies.
If a leak occurs, it’s natural to feel rushed, but
first perform temporary measures, and if construction is needed, calmly consider your options to ensure you won’t regret your choices!
Kakeru Koumuten Co., Ltd. is happy to assist with emergency leak repairs as well!
Check if the company conducts leak investigations and roof repairs in-house
Leaks can sometimes be easily identified, while in other cases, pinpointing the cause can be quite challenging, requiring knowledge and experience.
Contractors that completely outsource roof repairs and leak repairs to subcontractors may lack the necessary knowledge and experience, leading to suggestions for repairs in the wrong areas or unnecessary leak repairs.
Moreover, relying on subcontractors after an investigation can incur additional time and costs.
By having the knowledge and experience to perform the work in-house, responsible leak repairs can be conducted quickly and cost-effectively.
Kakeru Koumuten Co., Ltd. handles everything from leak investigations to construction in-house!
