  • Protection from the Ocean elements

    I was introduced to the Seal-it products in 2022 and cannot believe the incredible results they provided!  Especially in offering protection from the Ocean elements for the boat dock and wood decks around my home in the Outer Banks!  My neighbors keep asking me how I keep the dock and deck areas looking in such awesome condition--even better shape then what they have built themselves more recently! This product has offered outstanding protection from the salt air and erosion which is so common in this Ocean Community, such an effective process and I recommend this for anyone to restore or protect their wood and concrete investments---perfectly ideal for the brutal North Carolina coast, thank you Seal-it International!

  • Wood Restoration

    We are happy to endorse SealMaxx of Greater Atlanta. Our experience was very positive on every level. The work done by David McWhirter and his crew was very satisfying from the process itself (We are particularly pleased with the restoration of a thirty year old trellis.) to the care given to our property and the clean up. We intend to use them for other work.

  • Saved me a fortune!

    SealMaxx treated my driveway about 3 years ago. The rain had been causing my drive to deteriorate, and the aggregate was starting to become exposed. I knew that it was only a matter of time before I was going to be forced to replace the driveway. The SealMaxx guys came out, and in one day cleaned and sealed the concrete. Ever since then, the driveway has not worn away one bit. SealMaxx has no doubt saved me a fortune I would have had to spend on removing and having a new driveway poured.

  • No expensive re-sealing required

    SealMaxx restored my 19 year old deck, which was grey and ugly, and made it look new again. It is great to know I will never have to worry about sealing it again, as I have done that in the past, and it can get expensive. I looked at other companies, but everyone else just bought some sealant at a hardware store and put it on for you. SealMaxx’s 25 year guarantee is well worth the little bit of extra money up front. SealMaxx was a great solution for me, as it would be for anyone with a wooden deck.
