Tile Deep Clean & Seal
The kitchen floor with grout that started life as warm gray and has drifted to splotchy after fifteen years of mop water, dropped olive oil, and pet bowl spills nobody fully cleaned up. The master bath shower with a soap-film haze on the wall tile that no regular cleaning has fully pulled off and a grout joint that no longer beads water because the sealer wore through five years ago. The mudroom tile with salt and grit ground into the joints from a decade of Pacific Northwest wet boots. The entry tile that has the foot-traffic shadow at the front door where the grout is two shades darker than the rest of the field. Tile deep clean and seal is the Handis residential restoration scope for resetting a tile field to a finished state through mechanical cleaning of the grout, then re-sealing with a penetrating sealer that keeps the next decade of household life from accumulating in the joints. Oxygen-based grout cleaner (Aqua Mix Heavy-Duty, MAPEI UltraCare Heavy Duty, Stone Pro Heavy Duty) agitated with a Drill Brush attachment on a corded drill, rinsed clean, then two coats of a penetrating sealer (Aqua Mix Sealer's Choice Gold, TileLab SurfaceGard, or StoneTech BulletProof on natural stone) wiped on after 24-hour dry time. The maintenance cadence that pays back ten times its cost in extended floor life. From $400 for a single bathroom up to $1,000 for whole-house kitchen plus two baths. One to two visits, no licensed-trade handoff.

What Tile Deep Clean & Seal Includes
Tile deep clean and seal is the residential restoration trade for resetting a tile field that has accumulated household soiling in the grout — mop water residue, body oil, soap film, dropped cooking oil, salt and grit from wet boots, pet accidents that were not fully cleaned, the foot-traffic shadow at the front door — and then re-sealing with a penetrating sealer that resists the next decade of accumulation. Two-step process: oxygen-based grout cleaning with mechanical agitation, then two-coat penetrating sealer after the field dries. The annual maintenance pass that pays back ten times its cost over the life of the tile floor.
Pre-Inspection — Confirm the Field Is Right for Cleaning, Not Regrout
Walk the tile field and thumbnail-test the grout in several inconspicuous joints to confirm the grout is structurally sound (resists the thumbnail, holds together when scratched). Pulverizing grout, missing chunks, or failing change-of-plane joints route to regrout instead of cleaning — the cleaning step cannot restore grout that has lost structural integrity. We tell you on arrival when the field is past cleaning and quote the regrout instead. Honest scope before the bottle comes out.
Oxygen-Based Grout Cleaner with Mechanical Agitation
Aqua Mix Heavy-Duty Tile & Grout Cleaner, MAPEI UltraCare Heavy Duty Cleaner, or Stone Pro Heavy Duty Tile and Grout Cleaner applied at product-spec dilution (typically 1:4 with water for kitchen and bath, full-strength for the worst-soiled mudroom and entry tile). The cleaner dwells on the grout 5 to 10 minutes per product spec to break the bond between the soiling and the grout pore network. Then mechanical agitation along every joint with a Drill Brush attachment on a corded drill (the most effective tool for residential grout work — bristle-style attachment in 4-inch or 5-inch diameter) or a stiff-bristle grout brush for tight joints. The mechanical action lifts the soiling from the pore network where chemistry alone cannot reach.
Rinse, Dry, and Re-Inspect Before Sealing
Rinse the field clean with water (a household pump sprayer or a wet vacuum on extraction mode for floor tile, a damp microfiber cloth for wall tile and backsplash). Dry the field 24 hours minimum — the sealer bonds to dry clean grout, not to a damp joint where the pore network is full of water. We come back the next day to re-inspect the field after dry-down and walk the homeowner through any spots that need a second cleaning pass before the sealer goes on. About 1 in 5 fields needs a second pass on a localized hot spot (heavy soiling concentration that did not fully lift on the first cleaning).
Two-Coat Penetrating Sealer Application
Aqua Mix Sealer's Choice Gold (the long-time gold-standard penetrating sealer for porcelain and ceramic grout), TileLab SurfaceGard, or StoneTech BulletProof for natural stone where the stone itself needs sealing along with the grout. Two coats. The first coat soaks into the grout pore network and seals the substrate; the second coat builds the barrier and gives the joint its full water-resistance. Each coat wiped on with a foam brush or a microfiber cloth, soaked 5 to 10 minutes, then the tile face wiped clean to remove any sealer residue before it dries. Second coat applies after the first cures 24 hours. The full job typically runs across two visits — clean and first coat on visit one, second coat and final wipe on visit two.
Five-to-Seven-Year Re-Seal Cadence on a Typical Use Cycle
A two-coat penetrating sealer on a kitchen, bath, or entry tile floor lasts five to seven years before the seal benefit drops and a re-seal is recommended. On a high-traffic mudroom or entry under wet-boot conditions the cycle shortens to three to four years. On a shower with heavy soap and conditioner use, four to five years. We tell you on arrival what to expect for your specific room and recommend a re-coat schedule before the seal actually fails — that way the field never has to start over from contaminated grout and the clean-and-seal cadence is a maintenance pass, not a recovery operation.
How Tile Deep Clean & Seal Works
Seven sequential steps from arrival inspection through oxygen-based grout cleaning, mechanical agitation, rinse and dry, two-coat penetrating sealer application, and final walk-through — the sequence Handis runs on every tile deep-clean and seal project.
Inspect the Field and Confirm Grout Is Sound for Cleaning
Walk the tile field and thumbnail-test the grout in several inconspicuous joints. Sound grout resists the thumbnail and holds together; failing grout pulverizes and routes to regrout instead of cleaning. Confirm the joint count, the rough square footage, and any natural stone areas that need a stone-specific sealer (StoneTech BulletProof versus porcelain-and-ceramic Aqua Mix Sealer's Choice Gold). Honest scope before the cleaner comes out.
Mask the Tile-Adjacent Surfaces and Stage the Tools
Mask the toilet base, the vanity baseboard, any threshold wood, and any natural stone where the cleaner could over-spray onto a sensitive surface. Stage the corded drill with the Drill Brush attachment, the stiff-bristle grout brush for tight corners, the wet vacuum on extraction mode for the rinse-water pull, a bottle of the oxygen-based cleaner at product-spec dilution, and a stack of clean microfiber cloths. Run a runner from the doorway to the work area.
Apply the Oxygen-Based Grout Cleaner
Pour the diluted cleaner into a hand-held pump sprayer or a small bucket. Apply to the grout field in sections of about 20 to 40 square feet so the cleaner does not dry before the agitation step. Let the cleaner dwell 5 to 10 minutes per product spec to break the bond between the soiling and the grout pore network. Watch for foaming on heavily soiled joints — that is the chemistry working on the accumulated body oil and soap film.
Mechanically Agitate Every Joint with a Drill Brush or Stiff-Bristle Grout Brush
Run the corded drill with the Drill Brush attachment along every grout joint at a steady walking pace. The bristle action lifts the soiling from the grout pore network where chemistry alone cannot reach. Use a hand-held stiff-bristle grout brush for tight corners, edges around the toilet flange, and any spot the power tool cannot reach cleanly. Re-apply cleaner to localized hot spots where the soiling is heavier than the field average.
Rinse the Field Clean and Vacuum the Rinse Water
Rinse the field with clean water from a hand-held pump sprayer or a damp microfiber cloth. Pull the rinse water with a wet vacuum on extraction mode (for floor tile) or wipe with a fresh microfiber cloth (for wall tile and backsplash). The rinse step has to pull every gram of dissolved soiling and cleaner residue off the field — any residue left behind compromises the sealer bond.
Dry the Field 24 Hours and Re-Inspect Before Sealing
Dry the field 24 hours minimum before the sealer applies. Sealer bonds to dry clean grout, not to a damp joint where the pore network is full of water. Return the next day for the sealer application visit and walk the field with the homeowner before sealer goes down — any localized hot spot that did not fully lift on the first cleaning gets a second cleaning pass before the sealer commits.
Apply Two Coats of Penetrating Sealer with Tile-Face Wipe-Down Between
Wipe the first coat of Aqua Mix Sealer's Choice Gold (or TileLab SurfaceGard, or StoneTech BulletProof on stone) into every grout joint with a foam brush or microfiber cloth. Soak 5 to 10 minutes. Wipe the tile face clean with a damp microfiber to remove any sealer residue before it dries on the tile. Cure 24 hours. Apply the second coat the same way. Final wipe-down. Walk the field with the homeowner — demonstrate water beading on the sealed joints, confirm the seal coverage.
Tile Deep Clean & Seal Pricing
Final pricing depends on room size, joint count, joint width, accumulated soiling level, and whether the field includes natural stone (which needs StoneTech BulletProof or equivalent stone-specific sealer rather than porcelain-and-ceramic Aqua Mix Sealer's Choice Gold). Two-coat application is standard scope. Request a free estimate for an accurate quote.

Why Handis for Tile Deep Clean & Seal
Most tile floors we are called to deep-clean have been mop-cleaned with a household pH-neutral cleaner for years and look surface-clean but have accumulated soiling deep in the grout pore network where regular mopping cannot reach. The mechanical agitation step with the Drill Brush attachment lifts that deep soiling out — homeowners regularly tell us the cleaning pulls out grime they did not know was there. Then the two-coat penetrating sealer keeps the next decade of household life from accumulating in the same way. The cleaning is the recovery operation; the sealing is the prevention. Skip the seal step on a fresh-cleaned floor and the joints will be re-soiled inside two years; pay for the seal step and the cadence stretches to seven years.
Mechanical agitation with a Drill Brush — not just chemistry
Household mop-cleaners reach the surface of the grout joint but cannot lift soiling from the pore network where the bulk of the accumulation lives. We use a Drill Brush attachment on a corded drill to mechanically agitate every joint after the oxygen cleaner has had its dwell time. The combination of chemistry and mechanical action is what pulls the deep soiling out — chemistry alone leaves the pore network full, mechanical action alone scratches the tile glaze. Both together is the standard.
Oxygen-based cleaner, not acid, on cementitious grout
Acidic cleaners (vinegar, CLR, phosphoric acid) etch cementitious grout and accelerate its degradation. We use oxygen-based grout cleaners (Aqua Mix Heavy-Duty Tile & Grout Cleaner, MAPEI UltraCare Heavy Duty Cleaner, Stone Pro Heavy Duty) that lift soiling without etching the cement matrix. The cleaner is product-spec-diluted, dwells the spec time, and gets rinsed clean before drying. We do not use acidic cleaners on any cementitious grout, ever.
Two-coat penetrating sealer — single coat reads thin
Every job applies two coats of penetrating sealer. The first coat soaks into the grout pore network and seals the substrate; the second coat builds the barrier and gives the joint its full water-resistance. Single coats read thin and wear through inside two years on a high-use floor. The Handis quote includes two coats as standard scope.
Natural stone needs a stone-specific sealer, not porcelain-and-ceramic sealer
Aqua Mix Sealer's Choice Gold and TileLab SurfaceGard are formulated for porcelain and ceramic tile grout. On natural stone (marble, travertine, slate, limestone) the stone itself is porous and needs the same penetrating-sealer treatment as the grout — for that scope we use StoneTech BulletProof or Aqua Mix Sealer's Choice Gold (the same product also works for stone, with extended dwell time). The natural-stone sealer upgrade is line-itemed on the quote when the field includes stone.
Honest about when cleaning fixes the field and when regrout is the right call
A tile field with sound grout that has just accumulated household soiling is the right scope for a deep-clean and seal — we tell you on arrival and quote the work. A tile field with pulverizing grout, missing chunks, or failing change-of-plane joints is past the deep-clean scope; cleaning will not restore grout that has lost structural integrity. We route to regrout under shower regrout and recaulk (or to grout color sealing if the grout is sound but the color has drifted past what cleaning can restore). The honest call now saves the wasted visit later.

Customer Reviews
Recent tile deep clean and seal reviews from verified Handis customers.
Whole-house deep clean and seal on our kitchen and both baths. We had not sealed any of the grout since the house was built fourteen years ago. Tech ran the oxygen cleaner with a Drill Brush attachment, rinsed everything clean, came back two days later and applied two coats of penetrating sealer across every joint. Mop water beads up now where it used to soak in immediately.
Kitchen floor deep clean and seal on a 2008 install where the grout had gone splotchy from twenty years of olive oil and dropped sauce. Honestly did not believe the cleaning would pull the staining out, but the Drill Brush with the oxygen cleaner did exactly that. Field reads consistent again and the two-coat sealer keeps it from accumulating the same way going forward.
Mudroom tile deep clean and seal after a decade of wet boots and a winter of road salt tracked in. The grout at the door had nearly gone black. Tech double-cleaned the entry section because the soiling was concentrated there, then sealed the whole mudroom. The salt damage that I thought was permanent came out completely.
Master bath full clean and seal — floor, tub surround, and shower walls. Soap film haze on the shower walls had been driving me crazy for years. Tech mechanically agitated every joint and rinse-recovered with the wet vacuum so there was no run-off into the bathroom. The shower walls read clear glaze again and the floor grout is sealed against the next decade.
Entry tile deep clean and seal on a travertine floor that the previous owners had never sealed. Tech used StoneTech BulletProof on the stone surface itself plus an Aqua Mix Sealer's Choice Gold on the grout joints — two different products because the stone needed its own sealer. Three years later and the entry still reads like the day they finished.
