Happy Customers


Seriously people if you have a boat you need to get your cover and Bimini top from SewLong. We have had our boat covered with one for 7 years and it still looks new. We just got back from Powell and had some weather and unfortunately the cover ripped under the strain of rubbing against buoys in 60 MPH winds. Brought it in today and they’re going to fix it under a warranty I had no clue about. This is customer service personified. I was already thrilled with the quality of what we bought and now this. WOW is the only word that comes to mind. I have no doubt the repair will be awesome but I had to give them a review as this is a company that knows how to treat their customers.


Satisfied Customer

Sewlong & Clint have done a wonderful job creating a custom canvas cover, upholstery repair for the seats and aft sun deck on my boat at Lake Powell – terrific customer service! In fact, it just doesn’t get easier as all I have to do is call Sewlong and they get the job done. I highly recommend their services.

I stopped in last week to ask if you could fix the canvas for a heat houser for a 1959 Allis Chalmers tractor. Justin took time from his busy day to repair it while I waited. He did a great job and I wanted to let him know how much I appreciate his help!!!!
