Our Work Speaks. Soon Our Clients Will Too.

OH Grease Trap Pumping is the newest company in the One Hat family — which means our Google reviews are just getting started, and we'd rather show you real proof than borrowed praise. Here's what you can verify today: the One Hat family's 30+ year record serving San Diego, our up-front quotes (competitors hide theirs — ask yourself why), and the photo documentation we produce on every single job, samples below. Founding Client Offer: be one of our first 50 kitchens and lock your service rate permanently. As reviews come in, they'll live right here, unedited.

Every Job, Documented.
