I have used this service as a Christmas gift for my inlaws who are getting up there in years. We felt it was time to ween the ole guy away from his annual chore and reduce the risk of an accident. a gift was a nice approach.
The service uses a unique approach to vacuming the gutters cleanly vs blasting crud all over the siding, walkway and shrub beds below. Not to mention blasting crud onto yourself or the slippery ladder you stand on, if you clean your gutters yourself.
Easy to schedule process.
No one needs to be home.
Super clean process.
Easy to pay.
No injuries.
Initially chose the late fall sched cleaning, but now using the bi-annual sched as there are a lot of trees in the yard and gutters clog up pretty quickly.
Hope this helps you decide. I am a satisfied customer.
