Why the can't beat us - Our 5 step process
1. Site Preparation
We carefully isolate the work area, greenery and structures
2. Clean
We apply our environmentally-friendly, biodegradable soap with 160 (degree) hot water. We will use an orbital scrubber if necessary.
3. Rinse
We thoroughly rinse the cleaned surface until all the debris has been removed.
4. Seal
We then apply a flood coat of the appropriate SealMaxx sealant to cleaned surfaces.
5. Clean Up
The surface, now cleaned and sealed, will be ready for use in 24 hours. Before leaving we remove all protective tarps and supplies from the work area.
Before and After with Sealmaxx "We Seal St. Louis"

Testimonial "We Seal St. Louis"
"I just wanted to drop you a note to let you know how pleased Susan and I are with the SealMaxx process that David Monahan and his crew did on our redwood and cedar deck.
The process went as discussed in our conversation both over the phone and in a visit from Dave and Paul. The whole process went off without a hitch. Including working with our somewhat hectic schedules.
We concluded our project with their new PWS 1000 process that actually makes water bead on the surface. This process should last for 5 years before an additional application is required. It really makes the redwood grain stand out.
My only regret is that we didn't save some time, effort, and probably money, by NOT using the process immediately once the deck was completed."
