Kitchen island installation: a guide for pros
What customers ask, how to win the job, and what to put on your profile.
Offering kitchen island installation
Kitchen islands are judged on clearances, the seating and how the top sits flat over the base. Win the job by checking the layout and the utilities before the cabinets are ordered and showing the clearance plan on a drawing.
What customers ask
- Will there be enough room to walk around the island?
- Can I add a sink or a cooktop to the island?
- Will the island be strong enough for people to lean and sit on?
- How do you support the overhang for barstools?
- What outlets do I need in the island, and where should they go?
How to win the job
- Measure the clearances on all sides on the first visit, and mark the walking path and the door swings on the floor with tape.
- Show the island on a drawing with the clearances marked, and confirm the layout with the customer before the cabinets are ordered.
- Check the floor and the framing under the island location, and note any reinforcement or leveling needed in the quote.
- Quote the utilities as separate lines, with the licensed trade named and the permit steps listed.
- Name the overhang depth, the support method and the countertop material in the quote, with the seam location shown.
- Plan the outlets in the island with the code-required locations marked, and show them on the layout.
- Walk the finished island with the customer and check the clearance, the doors, the drawers and the seating height before you leave.
What to put on your profile
- Before and after photos of islands with the clearances and the seating visible
- Close-up photos of the overhang support and the seating edge
- Photos of the utility runs and the outlets in the island before the end panels go on
- A list of the island types and utility options you install
Follow-up that helps the customer
- A care sheet for the countertop and the cabinet finish on the island
- A check visit after the first few months to look at the overhang, the anchoring and the doors
- A quote for a matching pantry or a second island, offered only if the customer asks
Licenses and permits
Kitchen island installation often needs a permit when it adds electrical, plumbing or gas work, and that work often must be done by licensed trades. Confirm your contractor registration, insurance and trade partnerships in your state and locality before you take the job.
Questions
Should I warranty the island anchoring?
Warranty your anchoring and install work, and state that movement of the floor or the framing outside your scope is excluded. Name the anchoring method in the quote.
What if the floor framing will not carry the island?
Stop and show the customer the framing findings. Quote the reinforcement as a separate line and have it reviewed by a qualified person before the island is set.
