Tile Floors

The 1998 kitchen tile that has held up fine in the open field but is hollow at the dishwasher kick where the original installer skipped the uncoupling layer. The downstairs bathroom on the slab that has been cold under a sock for twenty Pacific Northwest winters. The large-format 12x24 porcelain a homeowner ordered from Pental that has been sitting in the garage for three months because no installer will quote it without the right thinset. The entry tile with a single cracked piece in front of the door from a moving-day dolly hit eight years ago. Tile floors is the trade for the four most common residential floor-tile scopes in Seattle homes — standard porcelain and ceramic in kitchens, baths, entries, and laundries; large-format tile that needs medium-bed thinset and lippage management; heated tile floors built around an electric mat with the thermostat circuit subbed to a licensed Washington L&I electrician; and tile floor spot repair for cracked, hollow, and popped tiles in a field that is otherwise intact. From $400 for a single-tile spot repair up to $9,000 for a large-format heated tile floor in a Seattle master bathroom. Handis self-performs every tile, thinset, grout, and uncoupling-membrane step; we are honest on the call about which scope finishes in a Handis-only visit and which needs the licensed electrician in the loop.

Pricing

Tile Floors Pricing

Final pricing depends on the room size, the tile format and material (porcelain, ceramic, natural stone), the substrate condition, the uncoupling and waterproofing membrane scope, and whether the project includes a heated mat with a licensed-electrician thermostat circuit. Each child page lists detailed pricing for that service family. Licensed-electrician sub fees on heated-mat projects pass through transparently with the line item named.

Why Seattle Homeowners Book Handis for Tile Floors

Most failed tile floors we are asked to fix started as a one-room kitchen install where the tile setter skipped two steps that take an hour each and saved a Saturday — the deflection check on the joist span (a tile floor wants L/360 with no movement under foot weight at the middle of the span) and the uncoupling membrane install (orange DITRA or pink Mapelastic between the tile and the wood subfloor). Both steps are cheap on a fresh install. Both are expensive to fix after the first cracked tile shows up at the threshold two winters later. Handis runs both checks on every floor we set, names what we find on the quote, and routes to a subfloor reinforcement if the span flexes more than the standard allows. The honest call now keeps the tile floor flat for the life of the build.

Estimate

Tell us the room (kitchen, bathroom, entry, mudroom, laundry), rough square footage, the tile format and spec if you have one (standard 12x12, large-format 12x24 or 18x36, gauged porcelain slab), the substrate (plywood or concrete), whether you want a heated mat, and any known issues (cracked tile, soft spot, threshold flex). We send a clear estimate with the licensed-electrician portion line-itemed on any heated-floor scope.

FAQ

Frequently Asked Questions

Common questions about Handis residential tile floor installation and repair — pricing, substrate prep, electric heated floors, large-format installs, and licensed-electrician handoff.

How much does a tile floor cost?
A single-tile spot repair starts at $400 and a multi-tile or bullnose repair runs to $1,500. A small bathroom or entry in standard-format porcelain or ceramic on DITRA underlayment starts at $2,500. A small bath in 12x24 large-format tile starts at $3,500. A heated tile floor in a small bathroom (40 to 50 square feet) starts at $3,500 including the licensed-electrician thermostat circuit as a line item. A full kitchen run in standard-format tile is $5,500 to $7,000. A master bathroom in 24x48 with adjacent hallway runs to $9,000. You get a written estimate before any work begins, with any licensed-electrician sub fees named line by line on heated-floor projects.
Do I need a Schluter DITRA underlayment under my tile?
On every wood subfloor, yes. DITRA (or DITRA-XL for low-build situations, or DITRA-HEAT when you want heating cable in the same product) is an uncoupling membrane that separates the tile from the wood subfloor's seasonal movement and from any hairline crack-through. Wood expands and contracts with humidity; tile does not. Without an uncoupling membrane the tile is rigidly bonded to a substrate that moves underneath it and develops hollows, hairline cracks, or popped tiles within a few seasons. On concrete slabs without crack history a direct thinset bond is fine; on slabs with hairline cracks we use Mapei Mapelastic AquaDefense as the crack-isolation membrane.
Can you do large-format tile that other installers turn down?
Yes. Large-format tile (12x24, 18x36, 24x48, and gauged porcelain slabs at 60x120) needs medium-bed thinset (Mapei Ultraflex LFT, Ardex X77, Custom Versabond LFT) trowelled with a 1/2-inch by 1/2-inch notched trowel, back-buttering on every tile to hit the TCNA 95 percent coverage standard, and a lippage clip system (MLT or Spin Doctor) on every joint. The substrate has to be flat to within 1/16 inch over 10 feet before the first tile goes down — most contractors turn the work down because they do not want to do the self-leveling prep with Ardex K 301 or the planetary grinder pass. We do both as standard scope on large-format and name them on the quote.
Does Handis install the heated mat AND the thermostat?
Handis installs the electric heating cable or mat itself — Schluter DITRA-HEAT, WarmlyYours TempZone Flex Roll, or Nuheat — integrated into the uncoupling membrane and set under the tile. We do not do the thermostat hookup or the dedicated 20-amp circuit run. Those are regulated electrical work that subs to a licensed Washington L&I electrician on every heated-mat project. The electrician runs the circuit from the panel, mounts the thermostat (Schluter DITRA-HEAT-E, WarmlyYours nSpire Touch, or OJ Electronics), terminates the cable, and runs the load calc. The licensed-electrician fee is named line by line on the quote so you see exactly who is doing what.
How long does a tile floor install take?
A single-tile spot repair finishes in one Handis visit (about two to three hours) plus a return for grout and seal after the thinset cures 24 hours. A small bathroom or entry in standard tile is two to three working days. A kitchen run in standard tile is three to five working days. A large-format tile floor adds a half-day to a day for substrate self-leveling and lippage management. A heated tile floor adds one half-day for the licensed-electrician site visits (rough-in and final). The thinset cure (24 hours) and grout cure before sealing (24 to 72 hours) are the schedule drivers on every install.
Will my plywood subfloor handle the tile, or does it need reinforcement?
Depends on the joist span and spacing. The TCNA standard is L/360 deflection for ceramic and porcelain (L/720 for natural stone) — meaning the floor should not deflect more than 1/360 of the joist span at the midpoint under load. Most modern construction (1995 and later) with 2x10 or 2x12 joists at 16 inches on center over a 12-foot span meets the standard. Older construction with 2x8 joists at 24 inches on center, or any span over 14 feet, may not. We check on arrival by walking the span and watching for movement at the middle, then confirm with a deflectometer if there is any doubt. If the span flexes we route to subfloor reinforcement (sister joists or a second layer of plywood) before any tile is ordered.
What is the difference between sanded and unsanded grout for floor tile?
Sanded grout (with fine silica sand mixed in for body) is the standard for joints 1/8 inch and wider — most floor tile installs. Unsanded grout (smooth, no sand) is for joints under 1/8 inch and for natural stone where the sand grains would scratch the polished or honed stone surface. The wrong grout in the wrong joint width fails — sanded grout in a narrow joint cracks because the sand grains do not pack into the joint, unsanded grout in a wide joint shrinks and pulls back from the tile edges. We match the grout type to the joint width on every install and name the product line on the quote.
Can you match the existing tile for a repair?
Owner attic stock first — most homeowners have a few extra tiles somewhere from the original install. If not we source from Daltile, Bedrosians, or Pental Surfaces for current-production lines (most 2010-and-later installs are still available). For discontinued lines we work the Seattle tile boneyards or wet-saw fabricate from a current-production tile when the bullnose or trim shape is the constraint. We tell you on arrival when the patch will be visible because the exact line is gone and never set a near-match without confirming with you first. A discontinued-tile sourcing surcharge is line-itemed on the quote when it applies.
How do I keep a tile floor looking new?
Sweep or dry-vacuum weekly to keep grit off the tile (grit is what scratches the glaze over time). Wet mop with a neutral pH cleaner (StoneTech Stone & Tile Cleaner, Aqua Mix Concentrated Stone & Tile Cleaner, or just warm water) — avoid acidic cleaners (vinegar) on cementitious grout and avoid bleach on colored grout. Re-seal the grout every two to three years on entry and mudroom tile, every five years on bathroom and kitchen tile. Two coats of a penetrating sealer (TileLab SurfaceGard, Aqua Mix Sealer's Choice Gold) wiped on, second coat after the first cures 24 hours.
Is the work guaranteed?
Yes. Handis carries general liability and workers' compensation; every technician has cleared a background screening before the first job. Our one-year project warranty covers tile setting, grout, sealer, and uncoupling membrane install — if a tile cracks, a hollow shows up, a grout joint pops, or a membrane bond fails inside a year because of our workmanship or prep, we come back and fix it at no charge. The licensed-electrician portion on heated-floor projects carries its own Washington L&I-trade warranty, also named on the quote so you know whom to call for what.
