Im a construction contractor and I can professionally seal driveways, walk ways, sidewalks, porches, patios and pool decks. If you are interested then i can come give a free bid and we'll go from there. I do not power wash, this is just sealing. Jobs can normally be completed in around an hour and will be good to walk on within 6 hours. Companies will overcharge to around 1000$ for 800 square feet but I will be around half for the same professional quality work. I look forward to making your concrete looking beautiful and protected!
