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, 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, repairs may be done for free within that warranty period.

Warranty periods vary by contractor and the type of work, but it is common to have a range 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 and aftercare services.

Kakeru Koumuten Co., Ltd. provides a leak warranty for both roof overlay and roof replacement work.
Similarly, exterior wall cover work and replacement work, as well as joint sealing work, also come with a leak warranty.
As part of our aftercare, we send out annual direct mail, 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, costs can vary between contractors, and warranties and aftercare services may differ as well.

Additionally, obtaining multiple estimates makes it easier to negotiate prices.

To request your desired repair contractor at a lower cost, it is essential to obtain estimates from multiple contractors.

If a leak occurs, it can be quite stressful, but
first, perform temporary measures, and when considering construction, taking your time to think it through will help ensure that you won’t have regrets later!
Kakeru Koumuten Co., Ltd. is happy to assist with requests for temporary 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 take time to pinpoint the cause, requiring knowledge and experience.
Contractors that completely outsource roof repairs and leak repairs to subcontractors may lack the necessary knowledge and experience, leading to repairs in the wrong areas or suggesting unnecessary leak repairs.

Additionally, having to investigate and then request a subcontractor can incur extra time and costs.
By having the knowledge and experience to perform the work in-house, we can provide responsible leak repairs that are quick and cost-effective.
