Testimonials

The team was very easy to work with, everything was explained in great detail without getting too technical. They were on time and performed the work in a timely manner and even went beyond what I expected. It was a pleasure dealing with a company that did such excellent work communication well and and left the workplace as it was when the arrived.
 - Edward S.
Our experience with Seal Strong, LLC, was pleasant and hassle free. We now have a peace of mind knowing our deck, porch and steps are sealed from all outdoor elements for 25 years. As a personal preference, we chose to put a stain on these areas. I would highly recommend Seal Strong LLC.
 - Bobby M.
Very thorough and communicative! Fantastic to work with and transparent as well!
 - Jason B.

My experience with this company could not have been more positive. I am so pleased with the end result of the treatment on my deck. I would highly recommend this company.

The Products We Use

Wood Sealant

  • It creates a permanent, effective seal against moisture, acids, time and weather, while hardening, increasing density and strengthening new or existing wood.
  • It does not colorize wood and allows for painting and/or staining wood surfaces. Paint and stains will last up to 300% longer with the sealant applied.
  • It seals old wood and will also re-seal aged pressure-treated wood.

Concrete Sealant

  • Permanent protection against spalling, alkali damage, water seepage, dusting, hairline checking and other types of concrete corrosion and deterioration.
  • Chemically reacts with concrete to create a new material, not concrete, not sealant, but a building material with the best properties of both. Our sealant protects concrete from the effects of acids, salts, oils, and more.
