What is not part of basement & crawlspace waterproofing
Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.
- Foundation repair, wall bracing, underpinning or replacing a failed wall. They are structural work and are a separate project.
- Any job where labor and materials together reach $1,000 or more is done by a licensed contractor, and waterproofing with excavation or a sump system passes that quickly.
- Mold remediation beyond cleaning surfaces the contractor treats. Larger growth is handled by a remediation specialist.
- Finished-space restoration, such as new drywall, flooring and paint after the water problem is fixed.
- Plumbing leaks inside walls or under the slab, which a licensed plumber diagnoses and repairs.
License and permits for basement & crawlspace waterproofing
Waterproofing mixes excavation, concrete, drainage and electrical work for pumps. The pros who do it hold the licenses their part of the job requires, and the license and insurance are shown on the pro profile.
Excavation, drain connections to a storm line or sewer, new electrical circuits for a pump and structural repairs commonly need a permit and an inspection. Your contractor normally pulls them.
Check the license and insurance on the pro profile and ask for a certificate of insurance. Ask for the permit, the written warranty and, for pumps, the model and maintenance instructions.

Before you book basement & crawlspace waterproofing
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Record when water shows up
Keep a note with dates, rainfall and the spot where water appears. Patterns tell a pro whether it is surface runoff, a high water table or a plumbing leak.
Check gutters and downspouts first
Clogged gutters and short downspouts can send water toward the foundation. Clearing them and extending the outlets is a simple step to mention to bidders, along with what you saw afterward.
Photograph the space
Take pictures of stains, efflorescence, cracks and any standing water, with a coin or tape for scale. Share them in the project so bidders come prepared.
Clear the work area
Move stored items away from walls and the sump pit. Clear access to the crawlspace hatch and note any low clearances for the crew.
Ask for the cause in writing
A good bid names why water is entering and ties the recommended fix to it. Be careful with bids that offer one system for every house.
Plan for power outages
If the bid includes a pump, ask about a battery backup and an alarm. Storms that cause flooding often cause outages too.
Say where in Berkeley you are
Add your neighborhood, for example Elmwood, North Berkeley, and Berkeley Hills, or your ZIP code to your notes. Pros choose the neighborhoods they cover, and it tells them how far they have to travel.

Best time to book basement & crawlspace waterproofing
Wet spring weather shows exactly where water enters, which helps a pro diagnose. Fall is a good time to install drainage before winter freeze and the next wet season, and dry soil is easier to dig and work in. In Berkeley, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain.

Berkeley Hills homes sit in a designated WUI fire zone, so ember-resistant vent screening and defensible-space prep are essential ahead of fall fire season.
