A countertop installation mistake can cost you thousands in repairs or replacements, so choosing the right contractor matters more than grabbing the cheapest bid. The difference between a sloppy install and a professional one shows up in uneven surfaces, grout failure, and premature edge chipping within months. This guide walks you through finding and hiring a contractor who'll get it right the first time.
Understand What You're Installing
Before you call anyone, know what material you're actually having installed. Granite, quartz, laminate, and tile countertops all require different skill sets and tools. A contractor experienced in intricate tile mosaics may not be your best choice for a seamless quartz slab install, and vice versa. Ask yourself: Are you replacing existing countertops, or is this new construction? Do you need backsplash work included? Will your contractor handle the sink cutout and edge beveling? These specifics change the scope and cost dramatically.
Check Licensing and Insurance
This isn't optional. A licensed contractor has passed local exams and maintains compliance with building codes—critical for countertop work because improper installation can lead to water damage under cabinets. Verify your contractor's license directly through your state or county licensing board's website; don't take their word for it. Confirm they carry liability insurance and workers' compensation. Ask for proof before they step foot on your property.
Review Their Countertop Portfolio
Ask for photos of completed countertop projects, ideally from the last 18–24 months. Look for consistency: Are edges clean and even? Are seams barely visible on stone work? Do tiles sit flush without lippage (uneven grout line heights)? Request to see at least three recent jobs in the material you're installing. Better yet, ask if you can contact past clients and actually call two or three to ask about their experience. A contractor confident in their work will have references ready.
Get Multiple Quotes—But Read Them Carefully
Collect quotes from at least three contractors, but don't pick based on price alone. A quote $3,000 below the others might mean they're cutting corners on substrate preparation, using cheaper materials, or they've underestimated the job. A legitimate quote should itemize labor, materials, removal of old countertops, leveling, backsplash, edge treatment, and sealing (for stone). Typical countertop installation runs $40–$150 per square foot depending on material complexity and your region; tile tends toward the middle, while high-end stone runs higher. The cheapest bid isn't the best deal if the contractor skips the cement board underlayment or seals stone improperly.
Ask About Timeline and Disruption
Countertop installation isn't a one-day job. Tile and stone typically take 5–10 days from removal through grouting and sealing. Some materials require curing time before you can use the countertop. Ask your contractor:
- When can they start?
- How many days will your kitchen be unusable?
- Will they handle the old countertop removal?
- What happens if the substrate (cabinets underneath) needs repair?
- Do you need to hire a separate plumber for sink installation, or do they handle it?
Verify Warranty Coverage
A trustworthy contractor stands behind their work. Standard warranties cover installation defects for 1–2 years and material defects vary by manufacturer. Get the warranty in writing as part of your contract. Ask specifically what's covered: grout cracking, seam failure, edge chips? Some contractors offer extended warranties for an additional cost.
Use a Contract, Every Time
Never start work on a handshake. A written contract should include project scope, materials specified by name and color, total cost, payment schedule (typically 50% down and 50% upon completion), start and end dates, and cleanup expectations. Include a clause about what happens if the job takes longer or costs increase due to unforeseen substrate damage. Protect yourself.

Frequently Asked Questions
Q: What should I do if my countertop isn't level after installation? Stop using it and contact your contractor immediately—unlevel countertops cause water pooling and accelerated wear. Legitimate contractors will return to fix this under warranty.
Q: Can I choose my own materials or must I use the contractor's supplier? Many contractors allow homeowner-supplied materials, but clarify this upfront; some include markup for sourcing, while others refuse responsibility if you buy elsewhere.
Q: How long should I wait before sealing my stone countertop? Most stone needs 48–72 hours to fully cure after installation before sealing; ask your installer for the exact timeline for your material.
