I highly recommend Northern Hot Tub Covers! In a time when hot tub covers were delayed due to COVID, this company was so wonderful. Every time I called I received a friendly person that let me know where my order was and approximate times. It ended up coming in on time, which was a surprise considering we’re in pandemic. And they nearly always answered the phone! Our cover looks and works great and we would certainly recommend them to anyone looking for a new cover!

I ordered the new cover online, the process was simple and help was available when needed. My cover was delivered to my door approximately 6 weeks after I placed the order. If you’re sceptical of ordering online like I was, don’t be, the cover looks and fits great. I upgraded my cover and still paid way less than what I had been quoted by other suppliers.

The cover received meet the standard as expected. I had order a fast production track that could not have been produce in the promised time. Northern Cover had reimburse those extra fee without delay and that his what I call: honesty. Cheers

I ordered my cover from Northern Covers in the middle of COVID. Every other company was going to take at least 6 months. Northern were very professional, prompt communication, good comparable pricing and excellent quality cover upon arrival. Thank you to David and team for getting me my cover! Will buy from this company again and highly recommend to others.
