What to know about Underpinning
Underpinning means deepening or widening an existing foundation by building new support beneath it, usually in short sections so the wall above is never unsupported for long. In American houses it comes up in three situations: a footing that has settled and has to be carried down to competent soil, a basement floor that a homeowner wants lowered for headroom in a rowhouse or a pre-war city lot, and an excavation next door that is going below the level of your footing.

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Interior or exterior approach
- Length of foundation wall to excavate or treat
- Depth, soil conditions and access for equipment
- Crack repair, underpinning or other structural work
- Weeping tile, sump pumps and backwater valves
- Restoring landscaping, driveways or finished basements
- Testing and safe removal of mould or asbestos, where needed
How to choose underpinning contractors in Sparks
- Choose a contractor who finds the source of the water before recommending a fix, whether that's grading, eavestroughs, cracks or drainage.
- Ask them to explain the difference between interior and exterior waterproofing for your home, and why they recommend one.
- For foundation cracks that are wide, growing or uneven, ask whether a structural engineer should assess them first.
- For mould, asbestos or radon, hire professionals qualified for that specific work, and don't disturb suspect materials yourself.
- Get a written quote that lists excavation, membranes, weeping tile, sump pumps and restoration of landscaping or finishes.
Questions to ask underpinning contractors before you hire
- Where do you think the water is coming from, and how did you confirm it?
- Do you recommend interior or exterior waterproofing for my home, and why?
- Should a structural engineer look at these cracks or this wall?
- Does this work need a permit from my municipality?
- Is your warranty transferable if I sell the house, and what does it cover?
- How will you restore the landscaping, driveway or basement finishes afterwards?
- If you find mould or asbestos, how will it be handled and by whom?
Underpinning permits in Nevada
Some underpinning work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
Licensing in Nevada
Consumer protection
The Board publishes a Home Improvement Bill of Rights: you have the right to hire only licensed contractors and to check the licence, to see past work and references, to get at least three bids, to pay as work is completed, not to pay cash, to withhold the final payment until the contracted work is done, to one project price covering all labour and materials, to a written payment schedule and completion date, and to require your contractor to obtain a building permit.

How many pros will contact me?
We introduce you to a small number of relevant pros — usually no more than three — so you’re not flooded with calls. If fewer pros are available in your area, we’ll tell you instead of promising quotes we can’t deliver.
Do I have to hire someone?
No. Requesting quotes doesn’t commit you to anything. Compare your options and hire only if someone is the right fit.
