I can not say how well or how poorly Leaf filter works but I have a pavilion in a campground more than an hour drive from my home. When I contacted them I explained exactly what I had ( 2 straight 40 foot sections 15 feet above the ground and asked for ball park figure or an average price per foot so I could make a decision on if it was worth my while to make the drive and wait on them to arrive. Stated that all jobs are different and wouldn't give any idea on an amount.
I set up an appointment and when they arrived they found that it was exactly as I had described. Gave me a price of $1995.00. ( which is nearly $25.00 per foot) I declined. The salesman was nice and did not try to pressure me.
Called another company told them exactly what I had. They told me over the phone that the price would be $200.00 ($2.50 per foot) if they didn't run into problems. They arrived at scheduled time did the job for $200.00 and
I am pleased.
Can't speak about the quality of leaf Filters product put can say I feel that they are way over priced and believe that you can can basically the same system installed for way less money elsewhere.
