What it is
Installing waterproof coatings and sheet membranes on decks, balconies, patios, small flat roofs and tiled shower areas to stop leaks and rot below.
Your first three steps
- Pick one or two product systems and complete the manufacturer's installer training
- Check your state and city rules for contractor licensing and any job-size limits
- Contact local remodelers, tile setters and property managers and offer to waterproof a trial area or small job
Who pays
Homeowners, condo associations, property managers, remodelers and tile contractors who subcontract the waterproofing step.
How it makes money
Price per square foot or per job. Subcontract work for remodelers and builders can give steady repeat jobs.
Skills that help
- Careful surface preparation
- Following product instructions exactly
- Measuring and estimating materials
- Reliable scheduling with other trades
Watch out for
- Contractor license requirements vary by state and city, so check before quoting jobs
- General liability insurance, since leaks can show up months later
- Weather and temperature limits for coatings, which can delay jobs
- Product warranties often depend on certified installers and correct prep, so keep records and photos
- Work at height on balconies and roofs, so check fall protection and safety rules
