How Long a Classic Restoration Takes, From the Shop Floor

A driver-quality mechanical refresh takes weeks to a couple of months. A true frame-off is a different animal: shops, including this one, plan around 800 to 1,200-plus hours of labour, and those hours land on a real calendar as a year or more. Hours are the work. The calendar is the work plus everything the work waits on.

How long does a restoration actually take?

“Restoration” is one word for at least four different jobs, and each carries its own clock. The table below is how the work plans out on a real floor — hours first, because hours are what you buy, then calendar, because calendar is what you live with. The money side of these same scopes — what the hours cost and why quotes vary — lives in the restoration cost guide. This page owns the clock.

Two of those numbers deserve their sourcing. The hour ranges for refresh, driver, and show work are the planning figures shops like this one actually schedule against — the same ranges the cost guide prices out. The top tier is Hagerty’s: a true concours restoration now runs 4,000 to 5,000 hours, and the shops doing that work carry backlogs measured in years.[1] On the calendar side, even a high-volume production restomod builder concedes that a traditionally built car takes twelve to twenty-four months or longer.[2]

The instinct is to divide: a thousand hours at forty hours a week is six months, so why does the car take a year and a half? Because your car does not get forty hours a week. It shares the floor with other builds, primer and paint cure on their own schedule, and the project waits — on parts, on plating, on decisions. The hours are the labour bill. The calendar is the labour bill plus the waiting, and no honest shop can quote the second number precisely before the car is apart.

What happens in each stage?

A frame-off breaks into five stages, and their share of the hours is nothing like equal. The proportions below are for a typical driver-quality build; a rustier car tilts further toward metal, a show car tilts further toward paint.

Teardown — call it a tenth of the hours

Everything comes off and everything gets bagged, tagged, and photographed, because assembly two stages from now depends entirely on how disciplined teardown was. This is also where the truth about the car surfaces — the rust, the previous repairs, the missing pieces — and it is why a good shop puts a reassessment point right here, before the big money is committed. The blue project shell on the builds page shows what that moment looks like: front clip off, assumptions replaced by facts. If the car has been sitting for years, the wake-up protocol runs before teardown even starts — a seized engine changes the whole plan.

Metal and body — the biggest single share

A third or more of the hours on most cars, and the least visible work in the finished product. Rust cut out, new steel welded in, panels fitted and refitted until the gaps are right. Every hour here is an hour nobody will ever see, and it is the stage where the estimate moves most — because nobody knows what is under the paint until the paint is off.

Paint — a fifth, and most of it is prep

The spraying takes days. The preparation takes weeks: strip, prime, block, guide-coat, block again, until the panel is genuinely flat instead of shiny-over-wavy. Cure times are calendar, not labour — nobody can bill the hours primer spends hardening, but the car cannot move on without them. Hagerty’s own guidance to first-time restorers is blunt about the whole undertaking: it takes weeks and months, not days.[3]

Assembly — a quarter, and the stage that lies to you

Assembly photographs beautifully. The car visibly gains parts every week — driveline in, glass in, wiring loomed, trim hung — and owners understandably read that as the home stretch. It is also the stage most hostage to lead times. Chrome at the plater, a windshield seal on backorder, one correct piece of trim somewhere in a warehouse: assembly stalls not for lack of hours but for lack of boxes, which is why the long-lead orders should have gone out back at teardown.

Sorting — the last tenth, and the one everyone skips

The shakedown stage. It matters enough to get its own section below.

Why do restorations go over schedule?

Three causes cover nearly every overrun this trade produces:

• Parts lead times. Plating commonly takes months, correct glass and orphan-make trim can take longer, and on a Canadian build most catalogue supply crosses the border — exchange, shipping, and customs all add days the schedule has to carry. The defence is ordering long-lead items at teardown, not when assembly needs them.
• What the paint was hiding. A restoration estimate is a set of assumptions, and teardown converts assumptions into facts. Rust in the floors, rockers, or frame that was invisible on inspection day adds real hours the moment it is found. This is not the shop padding the bill — it is the car telling the truth for the first time in decades.
• Decision latency. The quiet one. Colour, trim, budget approvals, which carburetor — every open question eventually stops the car, and a decision the owner sits on for two weeks costs the calendar two weeks. The shop controls the hours. The owner is on the critical path more often than either side realizes.

The calendar is the price of doing it once.

Worth saying plainly: an overrun is not automatically a failure. A car that took four months longer because the metal was worse than anyone could see is a project that got done right. A shop that went quiet for four months is a different problem — the fix for that is in how the work is scheduled and communicated, below.

What is “sorting” and why can’t it be skipped?

Sorting is the shakedown: the deliberate stage where a freshly assembled car gets driven, fixed, and driven again until it behaves like a finished one. Every fresh build has a hundred small faults — a weep at a fitting that only shows warm, fasteners that settle and want re-torquing, an alignment that changes as the suspension takes a set, a carburetor and ignition that need dialing on real roads, squeaks and rattles that only appear at speed. None of that is poor workmanship. It is what new assemblies do.

Sorting gets skipped because it is the stage with no visible progress. The car looks done, the photos look done, everyone is tired, and the money is mostly spent. But a car delivered unsorted does not skip the debugging — it transfers it to the owner, one roadside surprise at a time, and it is how a good build earns a bad reputation. An honest schedule carries weeks of sorting, not days, and in Alberta it deserves real shakedown miles in decent weather — a car finished in the shop in February meets its sorting season in May.

Driver, show, or concours — how does the target move the timeline?

Same car, three clocks. A driver-quality build is finished to look right at ten feet and get driven hard — the 800-to-1,200-hour job in the table. A show-quality build is the same teardown with multiples of the finishing hours: block-sanding until panels are dead flat, the underside and engine bay finished to the same standard as the paint you can see, plating and detail everywhere.

Concoursis a different discipline again, because the standard stops being “beautiful” and becomes “correct.” Judging bodies like the National Corvette Restorers Society score cars against an as-manufactured standard — a deductive 4,500-point sheet covering operations, interior, exterior, mechanical, and chassis, where the benchmark is how the car left the factory, right or wrong.[4]Research, correct parts, and documentation become hours in their own right, which is how the total climbs into Hagerty’s 4,000-to-5,000-hour territory.[1]

The schedule-killer is moving the target mid-build. Deciding at the paint stage that a driver build should really be a show build reopens metal work that was signed off months ago — the most expensive sentence in this trade starts with “while it’s apart, why don’t we just.” Pick the standard before teardown, in writing, and let the calendar be built around it.

How does a good shop schedule — and what can you do about the calendar?

From the shop, expect four things in writing: a scope that names the standard being built to, a teardown-and-reassess point before the large money is committed, long-lead parts ordered early rather than when the line stalls, and a steady rhythm of photo updates. Silence, not slippage, is the real red flag in this business. Around here the rhythm starts before the build does — photos in, and a scope, sequence, and honest range back inside two business days. How the work itself is structured is on the restoration service page.

From your side of the bench, the calendar levers are real: answer decisions quickly, fund each phase so the car never waits on money, put deposits on long-lead parts when the shop asks, and hold the target standard steady. An owner who does those four things routinely saves more calendar time than any shop can.

The year is not the punishment. It is the method — teardown that tells the truth, metal done before paint, assembly that waits for the right parts, and sorting that catches the faults before you do. If you want to know what your car needs and how long it honestly takes, send photos through the quote page. You will get scope, sequence, and a straight read on both the number and the calendar — inside two business days.
