Grout is one of the most overlooked parts of any tile installation, yet it plays a critical role in both appearance and performance. Over time, grout absorbs dirt, oils, soap residue, and moisture. Even if tile remains in great condition, dirty or failing grout can make an entire floor, shower, or backsplash look worn and neglected.
At Rose Restoration, grout restoration is one of the most common services we perform for homeowners and commercial clients. Understanding the difference between rake and regrout, color sealing, and simple grout cleaning helps you choose the right long-term solution for your space.
This guide breaks down each option, when it’s appropriate, and what results you can expect.
Why Grout Becomes a Problem
Grout is cement-based and naturally porous. It absorbs contaminants that sit on top of tile, including:
Dirt and mud tracked through high-traffic areas
Soap scum in showers
Cooking oils and spills in kitchens
Hard-water minerals
Improper cleaning products
Old sealers that have failed
Over time, grout can darken, stain, crack, crumble, or lose adhesion. In showers, weakened grout can even allow water intrusion that leads to mold or structural damage.
Once discoloration or deterioration becomes noticeable, regular cleaning is no longer enough.
When Grout Cleaning Isn’t Enough
Professional tile and grout cleaning removes years of buildup, bacteria, and embedded residue. However, some situations require more than cleaning:
Stains that have penetrated deeply into the grout
Grout lines that have worn low or uneven
Cracking or missing grout
Mold or mildew that cannot be fully extracted
Previous coating or colorants failing
Grout that is structurally compromised, not just dirty
For these conditions, clients typically choose between rake and regrout or color sealing.
What Rake and Regrout Actually Is
Rake and regrout is a full grout replacement process. We remove the top layer of the existing grout (the raking stage) and then install fresh grout into the joints. This is not a cosmetic refresh—it’s a structural repair that restores the integrity of the installation.
Step 1: Raking the Grout Lines
We use specialized tools to remove a precise layer of grout, deep enough to eliminate stains, deterioration, and compromised material.
Importantly, raking is done at the beginning because it can create faint surface scratches on adjacent stone or tile. This is normal and expected. For natural stone surfaces, such as marble or limestone, our technicians return after raking to hone and polish the stone, removing micro-scratches and restoring a seamless appearance. This ensures the final finish looks clean, uniform, and undisturbed.
Step 2: Regrouting
New grout is installed carefully to maintain consistent depth, color, and spacing. Because grout colors vary with age and wear, this produces a significantly fresher, more uniform appearance than patching.
Step 3: Caulking the Perimeter
We always finish rake and regrout by replacing caulk around perimeters, corners, and vertical transitions. Caulk allows flexibility where walls and floors meet, preventing cracking as the building shifts naturally. Grout is rigid, so caulk is always the material used for movement joints.
When Rake and Regrout Is Recommended
Deep staining that cannot be cleaned
Cracked, missing, or crumbling grout lines
Structural deterioration in showers
Loose or hollow-sounding areas caused by moisture
Multiple grout colors from previous touch-ups
Rake and regrout creates a truly restored, long-lasting grout installation.
Color Sealing: When You Want a Cosmetic Transformation
Color sealing is ideal for grout that is still structurally sound but visually inconsistent. It involves applying a tinted, protective sealer over the existing grout lines.
This process:
Makes grout look uniform and freshly installed
Creates a stain-resistant, water-resistant surface
Protects against future discoloration
Significantly improves ease of cleaning
Color sealing is popular for kitchens, mudrooms, bathrooms, and entryways where grout becomes stained over time but remains intact.
When Color Sealing Is Recommended
Grout is structurally stable but discolored
Clients want a dramatic visual improvement without removal
Budget-friendly transformation is preferred
Grout lines are uneven in tone but not cracked or missing
Color sealing is not a fix for deeper failures. If grout is loose, hollow, or deteriorating, we always recommend rake and regrout instead.
Rake and Regrout vs. Color Sealing: How to Choose
Here is a quick comparison:
Issue: Grout is deeply stained → Best option: Rake and regrout or color seal depending on depth
Issue: Grout is cracking or missing → Best option: Rake and regrout
Issue: Client wants grout to look brand-new → Best option: Color sealing
Issue: Water intrusion concerns in showers → Best option: Rake and regrout
Issue: Cosmetic discoloration only → Best option: Color sealing
Issue: Uneven grout lines from previous repairs → Best option: Rake and regrout
Many homeowners choose to pair color sealing with rake and regrout for maximum longevity.
Why We Don’t Recommend Epoxy Grout for Most Residential Projects
Epoxy grout is extremely durable and stain-resistant, but it is not appropriate for every space. It can be difficult to install, challenging to repair, and inconsistent with the look of traditional grout lines in older homes.
We typically recommend epoxy grout only for:
Commercial kitchens
High-moisture industrial locations
Select heavy-use environments
For residential showers, floors, and backsplashes, traditional cementitious grout paired with proper sealing offers the best balance of appearance, longevity, and serviceability.
Why Professional Grout Restoration Matters
Property owners often try DIY grout cleaning or patching, but grout is one of the most delicate elements of a tile installation.
Professional restoration prevents:
Deep water intrusion
Mold growth behind tiles
Premature tile failure
Repeat cracking or deterioration from improper materials
Uneven color and joint spacing
High-quality tools, dust control, structural evaluation, and matching grout types are all essential for long-term success.
Real Client Example
A homeowner in Arlington had grout that looked dark and dirty no matter how often she cleaned it. The grout was stained beyond the surface level, and several joints were cracking near the shower threshold.
We performed a rake and regrout service followed by fresh caulking. Afterward, the client said her shower looked newly installed—bright, clean, and uniform. The improvement was more dramatic than replacing fixtures or tile.
Final Thoughts
Grout plays a bigger role in your home’s appearance and durability than most people realize. Whether your grout is stained, cracking, uneven, or simply outdated, choosing the right restoration method can transform the entire room.
Rake and regrout offers a structural reset.
Color sealing offers a cosmetic reset.
