How much buffer time should a handyman leave between back-to-back jobs?

Why the buffer is not just drive time

Drive time is the easy part; you can look it up. The buffer that actually matters covers everything else that happens between the last screw and the next doorbell: walking the customer through the work, collecting payment, loading the truck, a phone call from tomorrow's customer, a stop for a part you did not expect to need. On an ordinary day those tasks add up to more than the drive. If your calendar only accounts for travel, you are late to the second job most days and cannot explain why.

The second reason for a buffer is variance. Estimates are averages, and real jobs land on either side of them. A buffer absorbs the jobs that run long so the ones behind them do not have to. Without it, one job that goes sideways at 10 a.m. cascades through the afternoon and you spend the day apologizing. With it, a rough morning is a private problem and the afternoon customer never knows it happened.

Sizing the buffer by job type

Quick, well-defined tasks you have done a hundred times (a lockset, a ceiling fan, a couple of shelves) rarely need more than a short gap beyond the drive. You know the failure modes and you carry the parts. Jobs with hidden conditions deserve a longer buffer: anything involving old plumbing, drywall you have not opened, wiring in a house older than you are, or a "small" leak. These are the jobs where the estimate is a guess and the buffer is the honest acknowledgment of that. Related: What should a handyman do when a job runs longer than the estimate?

New customers need more buffer than repeat ones, regardless of the task. A first visit includes finding the house, meeting the dog, discovering that the "one door" is actually three doors and a closet, and a longer conversation at the end. Repeat customers already know how you work and their jobs run closer to the estimate. Many handymen use two rules: a standard gap for known work with known customers, and a longer one when either the job or the customer is new.

Where to put the buffer in the day

Buffer placement matters as much as buffer size. Front-load the risk: put the uncertain job first and the predictable one after it. If the uncertain job runs long, you compress the gap in front of the predictable job, and predictable jobs tolerate compression. Reverse the order and a late-day surprise has no room left to land in. Some handymen leave a slightly longer gap after lunch for the same reason, since that is where the morning's overrun tends to pile up.

End the day with a job that can flex. A customer who said "any time this afternoon is fine" is a better last stop than one who has a hard 4 p.m. leaving time. Keep one deliberately loose slot late in the day and treat it as the release valve for the whole schedule. When the morning goes cleanly, you arrive early and finish early. When it does not, you still finish, just later, and nobody was stood up.

Tuning the buffer with your own history

The right buffer is not a universal number, it is your number, and you find it by looking at your own jobs. Keep the estimated time and the actual time on every job for a month, then look at how often you ran over and by how much. If a certain category runs over regularly, the fix might be a longer buffer or it might be a better estimate; either way you now know. Handymen who do this usually find that a small number of job types cause most of the overruns.

Adjust seasonally too. Exterior work in summer has different variance than interior work in winter, and the first weeks of spring bring the kind of "while you are here" requests that eat gaps. If you use a scheduling tool, set a default gap and override it per job rather than fighting a single fixed value. HandyPlanr lets you set the default and adjust per booking, but a paper planner with a rule you actually follow beats software with a rule you ignore.
