The Most Common Acoustic Guitar Repairs (and What They Cost)

The Eight Repairs That Account for 90% of Bench Work

Across roughly 2,400 acoustic repairs I have logged since 2010, eight specific problems account for approximately 90% of everything that comes across my bench. In rough order of frequency: setup and action adjustment (about 30% of jobs), fret crowning and leveling (15%), nut and saddle replacement (12%), bridge reglue (9%), neck reset (8%), loose brace repair (7%), top crack repair (6%), and headstock break repair (3%). The remaining 10% is a mix of pickup installation, tuning machine replacement, binding repair, and finish touch-up.

Knowing what a repair costs before you walk into a shop prevents two common mistakes: being overcharged by a general music store for basic work, and being talked out of a repair that is actually worth doing on an otherwise good instrument. A full setup should cost $60-100 in 2026. A neck reset on a Martin D-28 runs $450-650. A bridge reglue is $180-280. These prices are from a working luthier's shop, not a mall guitar store, and they apply to 90% of the repair work the average acoustic owner will ever need.

Setup and Action Adjustment ($60-100)

A proper acoustic setup includes checking neck relief, adjusting the truss rod if needed, filing the saddle for correct action height, cleaning the fretboard, and bringing the strings to pitch with a fresh set. A competent luthier will complete this in 45-60 minutes and charge $60-100 depending on location and complexity. Any guitar that sounds harder to play than it should, fretted notes that require excessive force, chords that buzz, high action at the 12th fret, needs a setup before any other repair is considered.

The factory setup on a new guitar is almost always a starting point, not an endpoint. Even a Martin D-28 straight from Nazareth, PA benefits from a proper setup tailored to the player's hand strength and playing style. I measure action at the 12th fret on every instrument that comes through the shop: low E should typically sit 2.0-2.4 mm above the 12th fret, high E at 1.6-1.8 mm for most players. Anything significantly above those numbers is causing the player more fatigue than necessary.

Fret Work ($120-300)

Fret crowning and leveling is the most common repair beyond basic setup, and it is where amateur work does the most damage. The process involves filing the tops of all frets flat to a common plane, then recrowning each one to restore its rounded profile, then polishing. A full crown and level on a 20-fret acoustic takes 2-4 hours of bench time and costs $120-220 at most shops. A full refret, where every fret is removed and replaced, is a much bigger job and runs $300-500 depending on fretwire choice.

The signs that you need fret work are specific: notes that sound out (choke) on certain frets when bent, intonation that cannot be corrected at the bridge, visible wear grooves on the 1st-5th frets, or a fretboard that has uneven heights visible under a straight edge. I use a Stew-Mac notched straight edge for initial assessment and a Stew-Mac fret rocker for final checking. A guitar that needs fret work will often feel 'cured' after the job, playability improves more dramatically than most players expect.

Nut and Saddle Replacement ($60-180)

Bone nuts and saddles are the correct upgrade path for any guitar with plastic (often labeled 'Tusq' or just 'synthetic') components. A proper bone nut and saddle installation on an acoustic typically costs $80-180 combined, including the materials. The tonal improvement is measurable: on my reference Taylor 114ce, swapping the stock Tusq components for bone produced about 1-2 dB more high-frequency energy and a noticeably longer sustain tail on open strings. For a $15 parts cost plus labor, it is one of the best value upgrades available.

The other common nut issue is incorrect slot depth. Factory nuts are often cut slightly high to avoid returns from players who hear open-string buzz. The result is excessive action at the 1st fret, which makes cowboy chords harder than they need to be. A proper nut slot depth is specified by measuring fretted action at the 2nd fret with the string pressed at the 3rd fret, the clearance should be about 0.15-0.25 mm. Most factory nuts sit closer to 0.4-0.5 mm, which is why a professional nut adjustment often transforms a guitar's feel overnight.

Neck Reset ($400-700)

Neck resets are the repair that makes most owners consider selling their guitar instead. On a Martin or Gibson acoustic, a full neck reset involves steaming the neck joint loose, re-seating the neck at the correct angle, and refinishing any affected areas. It costs $400-700 at most reputable shops and takes 2-4 weeks of calendar time. A neck reset is necessary when the saddle cannot be filed any lower without losing string break angle, when the 12th-fret action exceeds 3 mm on the low E even with a minimum-height saddle, or when the top has distorted enough that the neck angle has changed by more than 1 degree.

Most Martin dreadnoughts from the 1970s-1990s need a neck reset by year 30-40. Gibson slope-shouldered J-45s and J-50s often need them earlier because of the top's tendency to belly under string tension. Taylor's bolt-on NT neck system eliminates most neck-reset work entirely, the company designed it specifically to make angle corrections a 30-minute shim swap rather than a multi-week rebuild. If you are buying a vintage Martin over 30 years old, always have a qualified luthier check the neck angle before completing the purchase.

Top Cracks and Brace Repairs ($120-400)

Top cracks on acoustic guitars almost always come from humidity extremes, usually during dry winter months when indoor air drops below 30% RH. A clean, simple crack that has not spread through the bridge plate or X-brace can be repaired with hot hide glue for $120-220 and will be visually nearly invisible after refinishing. Complex cracks that cross bracing or extend through the bridge plate run $250-400 and take longer to stabilize. I see the most crack damage on guitars that lived in Colorado, Utah, or Arizona without humidification.

Loose braces are a subtler problem. A guitar with a loose brace produces a buzz or rattle that only shows up on specific notes, often around the 3rd-5th fret on the low E or A string. The repair involves injecting hot hide glue through the existing crack or gap, clamping, and waiting 24 hours for full cure. It runs $150-300 depending on access difficulty. The easiest way to detect a loose brace yourself is to tap the top with a fingertip in different locations, a healthy top sounds consistent, while a loose-brace area has a dead, duller tone.
