Baseboard installation: a guide for pros
What customers ask, how to win the job, and what to put on your profile.
Offering baseboard installation
Baseboard work is judged on tight corners, straight runs and the caulk line at the floor, and customers notice a gap in a long run quickly. Win the job by measuring the walls, planning the stud fastening and showing the profile on a sample.
What customers ask
- Will the corners stay tight after the new floor goes in?
- Can you reuse the old baseboard, or do I need new?
- Will the paint or stain match the rest of the trim?
- How do you handle the gap where the floor meets the wall?
- Will you patch the walls where the old baseboard came off?
How to win the job
- Look at the walls and floor on the first visit, and note any out-of-plumb or out-of-level conditions that affect the install.
- Show a sample of the profile in the room with a corner cut, so the customer sees the height and the joint.
- Quote the removal and patching of the old baseboard as separate items, with the number of rooms and the linear footage.
- Name the profile, the nails and the caulk in the quote, and state that the pieces are fastened into the studs.
- Explain how the gap at the floor will be covered by the baseboard and the caulk, and how the flooring will be trimmed to match.
- Schedule the baseboard after the flooring and before the final paint, and state that order in the proposal.
- Walk the finished rooms with the customer and check each corner and the caulk line before you leave.
What to put on your profile
- Before and after photos of rooms with the baseboard visible, showing the corners and the floor line
- Close-up photos of coped corners and the caulk line at the floor
- Photos of the nailing into studs before the filler and paint go on
- A list of the baseboard profiles and heights you install
Follow-up that helps the customer
- A caulk and touch-up note for the baseboard, with the paint color and sheen used
- A check visit after the first heating season to look at the corners and the floor line
- A quote for matching baseboard in another room, offered only if the customer asks
Licenses and permits
Baseboard installation commonly does not need a license or a permit, since it is finish work. Confirm your business registration and insurance in your state and locality before you take the job.
Questions
Should I warranty the install?
Warranty your workmanship on the corners, the fastening and the caulk. State that gaps from a floor that moves or settles are outside the warranty.
How do I handle a floor that is out of level at the wall?
Scribe the baseboard to the floor or cut the bottom edge to follow the floor line. Show the customer the gap and explain how the caulk will close it.
