3" Wide Joist Gasket Tape

As a contractor Trademark is my go to Soundproofing Company on every project I do. I have not found anyone else that comes close to their knowledge (and every project different twist and turns). Add to that their amazing customer service and huge stock of material and that is the reason I won't go anywhere else. Thank you Trademark!

The Web site was very easy to navigate to find the right product you are looking for! Communication is fantastic with emails on when you item will arrive, The item that I purchased worked like a charm and looks great on the doors. Super Service

Premium carpet underlayment - a wonderful solution to second floor noise and footfall dampening in a home with open beam first floor ceiling treatment. Elie was so helpful in educating us on the right product - and lead time and delivery were as promised, in a year when nothing else was!

Great company and product!

Great responsiveness when there was a problem with shipping being just by carrier. They took care of it and I received my shipment quickly after asking for their help. Highly impressed

I was at my wit's end! 15 years of barking dogs, and calling animal control. This was my last desperate resort.
Even though they were pricey, I had to try them.
I am so happy!!!
They didn't completely block out the low frequent bass and truck engines, but NO BARKING!
I can sit in my little library, and lose myself in another world, without the constant nagging barking of my neighbor's dogs. (It never stops when she's not home, which is all day every day.)

I purchased three times a very good customer service the person name Elie helped me with my order and I will buy again

I purchased the electrical outlet soundproof seals, and they are extremely effective! I was doubtful when I purchased, but it does make a huge difference. THANK YOU!

Amazing customer service and the best price! There are very few companies that can compare with this kind of service! A+!

Their products work great and they have great service
I Highly recommend them

Have ordered half a dozen times from Trademark Soundproofing with nothing but positive results. Their product performs as promised and their customer service has been excellent. They have accommodated my needs beyond expectations. had one issue with an order that was delivered slightly different than ordered. Trademark shipped out the missing product quickly without cost or questions. Highly recommended.
