Sink & Faucet Installation in Schaumburg, IL

That is the Village of Schaumburg Community Development Department — Permit Services's call, not ours — (847) 923-4420. The general shape of it is that cosmetic work is usually outside permit scope and anything that adds or moves electrical, plumbing or gas usually is not. Where Schaumburg publishes a rule we follow it; where it does not, we say so in the quote rather than assuming an exemption on your behalf.

The black ring is water damage — iron-tannin staining plus fungal darkening from standing water, and it is the classic butcher-block failure around sinks. Prevention is a rhythm, not a product: keep the sink perimeter caulked, wipe up standing water instead of letting it sit, and re-oil with food-grade mineral oil or an oil-wax blend monthly for the first year and quarterly after, more often right at the sink. If black spots appear, sand to bare wood, treat with oxalic-acid wood bleach, and re-oil; if the wood is soft or the stain returns immediately, water is getting underneath the finish and the section around the sink may need replacement.

Black marks are water stains — standing water reacting with the wood. Three habits prevent them: towel-dry the area around the sink every time (never let water pool), oil the wood monthly with food-grade mineral oil including the sink cutout edges, and top with a beeswax board cream so water beads instead of soaking in. If black spots have already formed, oxalic-acid wood bleach followed by sanding and heavy re-oiling can reset the surface — a repair no stone counter offers.

Count every deck item before fabrication: the faucet (one hole for most single-handle models, two at 8 in centers for a bridge), soap dispenser, dishwasher air gap where local plumbing practice requires one, and any filtered-water or instant-hot tap. Each hole costs roughly $65-$120 drilled at the shop; adding one to installed stone later is risky and many fabricators refuse the job. If you are unsure about a future accessory, drilling the extra hole now and capping it is far cheaper than wishing for it later.

National figures from early 2026: a drop-in swap runs about $300-$900 installed, an undermount $500-$1,400, and a farmhouse conversion $700-$2,200 once cabinet work is included. Doing it alongside new countertops is the cheap moment - the cutout, edge polishing, and faucet holes are part of fresh fabrication instead of risky rework on installed stone, and you pay for plumbing disconnect/reconnect once instead of twice.
