Cracked, crumbling, or stained grout makes a tiled surface look old and can allow water to work its way behind tiles. Regrouting and grout repair are affordable maintenance tasks - but the cost varies based on how much grout needs work and who does the job.
Tile Grout Repair Cost in 2026
Spot repair (small area, 1-5 sq ft): $100-$250 Bathroom floor regrout: $200-$600 Full shower regrout: $300-$800 Kitchen backsplash regrout: $150-$400 Grout sealing only (existing grout): $75-$200
Labor typically runs $5-$15 per square foot for grout-only work, depending on the complexity (tile size, joint width, accessibility) and your location.
What's Included in a Professional Regrout
- Removing the old grout (usually with an oscillating tool or grout saw)
- Cleaning the tile surface
- Applying new grout in matching color
- Wiping and buffing the tile clean
- Applying grout sealer (sometimes included, sometimes extra)
Color matching is the tricky part. New grout is often a slightly different shade than old grout, even if it's the same product - because old grout has years of buildup. For a full regrout, this isn't an issue. For spot repairs, color matching takes skill.
DIY vs. Hiring a Tile Contractor
DIY is very doable for: - Small areas with cracked or missing grout in accessible locations - Resealing existing grout in good condition - Color-matching is not critical (utility room, laundry area)
Grout repair kits are $10-$25 at hardware stores. A grout saw and new grout are the main tools needed. Expect to spend 2-4 hours on a small bathroom floor spot repair.
Hire a pro for: - Full shower regrout (working around shower valve, tight corners) - Large areas where color consistency matters (master bath, kitchen floor) - Grout that's cracking due to substrate movement (not just surface wear) - Epoxy grout (much harder to work with than standard cement grout)
Signs the Problem Is More Than Grout
Tiles are loose or hollow: Tap tiles with a knuckle. A hollow sound means the tile adhesive has failed. Regrouting won't fix this - tiles need to be removed and reset.
Crack runs across both tile and grout: This is usually substrate movement (the subfloor flexing). Without addressing the substrate, new grout will crack again.
Water behind the tile: If grout has been failing in a wet area for a long time, water may have penetrated behind the tiles. In showers, this can mean waterproofing membrane damage and mold. A simple regrout won't solve it.
Grout Sealing: Worth Doing?
Yes - especially in showers, kitchen counters, and bathroom floors. Grout is porous and absorbs water, cleaning chemicals, and stains without sealing. A quality penetrating sealer ($15-$30 per bottle) applied every 1-2 years keeps grout looking clean and prevents water infiltration.
Professional sealing service runs $75-$200 for a bathroom. Easy to DIY on the maintenance schedule.
How to Find a Good Tile Contractor
California recognizes C-54 Ceramic and Mosaic Tile Contractor as a specialty classification. Whether a particular grout-only repair requires a licensed contractor depends on the full scope, permit requirements, use of workers, and total project price. Check current CSLB guidance and then review: - Reviews on multiple platforms - Photos of past work (grout lines should be consistent and clean) - Ask if they'll do a small test area first on color-sensitive jobs
Bottom Line
Spot grout repair costs $100-$250 for a small area. Full shower regrout runs $300-$800. Simple spot repairs and grout sealing are reasonable DIY tasks. Full regrouts and large areas are worth hiring out for quality results.
