Tile installation questions, answered
46 real questions homeowners ask about cost, timeline, materials, and waterproofing — covering the seven services DGJ installs across Metro Detroit.
Cost & estimates
How much does tile installation cost?
Cost depends on the room, the tile you choose, and what condition the surface underneath is in — there's no single number that applies to every job. A kitchen backsplash and a full master bathroom aren't priced the same way, and neither are two bathrooms with different subfloor conditions. {{PLACEHOLDER: price range}} The only way to get an accurate number is a free, in-person estimate for your specific project.
Why do tile installers charge so differently for similar jobs?
Because "similar" jobs often aren't, once you look at what's actually involved — subfloor condition, tile size, pattern complexity, and whether demo is included all change the labor hours behind the price. A low quote sometimes means skipped steps like proper waterproofing or substrate prep, not a better deal. Ask what's included, not just the bottom-line number, before comparing two quotes side by side.
Do I have to pay for an estimate?
No — DGJ Tile & Marble gives free, in-person estimates on every project. Dervin comes out, looks at the actual space, and gives you a real number before you commit to anything. There's no charge and no obligation to hire, whether you move forward or just wanted a number to plan around.
Is the estimate the final price, or can it change?
A written estimate should reflect the final price for the scope discussed — it shouldn't change unless the scope itself does, like discovering subfloor damage once demo starts that wasn't visible beforehand. Ask any installer directly how they handle a surprise found mid-job, and get the answer in writing before work begins, not after.
What's included in a tile installation quote?
A real quote should spell out the tile and material cost, labor, substrate prep, waterproofing where relevant, and whether demo and disposal of the old surface are included. {{PLACEHOLDER: demo and disposal policy}} If a quote doesn't break these out, ask — a vague one-line number makes it hard to know what you're actually paying for.
Do you charge more for large-format tile?
Often yes, because large-format tile takes more time to set correctly — it needs a flatter substrate, full mortar coverage to avoid hollow spots, and more careful handling since the tiles are heavier and easier to crack. It usually means fewer grout lines and a cleaner look, which is why homeowners choose it anyway despite the added labor.
Does the price change if I supply my own tile?
{{PLACEHOLDER: tile supply policy}} Either way, the tile itself affects labor time independent of who buys it — large-format tile or natural stone takes longer to set than standard ceramic, no matter who supplied it, so the material choice moves the price more than who purchased it does.
How do I compare quotes from different tile contractors?
Compare scope before you compare price — make sure each quote covers the same work: demo, waterproofing, materials, and cleanup. The cheapest number often has something missing, not a better deal on the same job. Ask each contractor what's included, request it in writing, and ask to see examples of finished work before deciding.
Timeline & process
How long does a tile installation take?
{{PLACEHOLDER: typical job duration}} A backsplash might be a day or two, while a full bathroom or master suite takes longer because waterproofing needs time to cure between steps. Your exact timeline depends on the scope of your project and comes with your estimate.
Why does tile take longer than other flooring?
Because tile isn't just laid down — the substrate has to be checked and prepped, waterproofing (where needed) has to cure, tile has to set before it's grouted, and grout needs its own cure time before the space sees regular use. Skipping steps to go faster is exactly how tile ends up cracked or a shower ends up leaking a year later.
Can I stay in my house during the project?
Yes, in almost every case — tile work is contained to the room being worked on. Expect some noise and dust despite containment efforts, and limited access to that specific room while it's underway. A full master bath remodel is the exception, since you'll likely want a second bathroom available for the stretch it's out of use.
What's the actual step-by-step process for a tile job?
It starts with a free estimate, then material selection once you've decided on tile, then the installation itself — demo, substrate prep, waterproofing where needed, tile setting, and grout — followed by a walkthrough where you sign off on the finished space. Each step depends on the one before it, which is why rushing the order causes problems later.
How far in advance do I need to book?
{{PLACEHOLDER: typical booking lead time}} Scheduling tends to get tighter during peak renovation seasons — spring and early summer especially — so it's worth reaching out for your free estimate as soon as you're seriously considering the project, even if you don't plan to start for a few months.
What happens if there's a delay mid-project?
If something comes up — a material backorder, or a problem found once demo starts — you should hear about it directly, with a revised timeline, not find out by wondering why nobody showed up. Ask any installer how they communicate delays before you hire them; it's one of the most common complaints homeowners have about contractors in general.
Materials & tile selection
What's the difference between porcelain and ceramic tile?
Porcelain is denser and less porous, which makes it more resistant to chipping and moisture — a real advantage in a kitchen or bathroom. Ceramic costs less and is easier to cut, and holds up fine in lower-traffic areas or for homeowners prioritizing budget over durability. Neither is wrong; see bathroom tile installation or kitchen tile installation for room-specific guidance.
Is marble a good choice for a busy household?
It can be, but it needs more care than porcelain — marble is porous, needs sealing, and etches from acidic spills like lemon juice or vinegar if they're not wiped up quickly. Many homeowners still choose it for the look and accept the maintenance trade-off; it's worth knowing about going in rather than being surprised by it later.
What tile size should I choose?
Larger tile means fewer grout lines and a cleaner look, but it needs a flatter substrate than smaller tile tolerates, or you'll see lippage — a ridge where two tiles don't sit perfectly level. Smaller tile is more forgiving on an imperfect surface and works better on curved or sloped areas like a shower floor. The room and the substrate both factor into the right call.
Do I need to seal my tile?
Porcelain and most ceramic tile don't need sealing — they're dense enough to resist moisture on their own. Natural stone like marble, travertine, and granite does need sealing, and grout of any kind benefits from it too, since grout is porous by nature. If you're not sure what you have, ask your installer directly rather than guessing.
What's the difference between tile and natural stone?
Tile — ceramic or porcelain — is manufactured, consistent, and generally lower-maintenance. Natural stone like marble, travertine, or quartzite is quarried, so no two pieces are identical, and it typically needs sealing and more careful handling during installation. Stone usually costs more, in both material and labor, but gives a look manufactured tile can't fully replicate.
Can I mix tile materials in one room?
Yes — a lot of higher-end projects mix a primary tile with an accent material, like a porcelain floor paired with a marble mosaic shower floor, or a natural stone fireplace surround that carries into an accent wall nearby. It takes more planning to make sure materials transition cleanly, but it's an effective way to add interest without tiling an entire room in an expensive material.
What is DCOF and why does it matter?
DCOF stands for dynamic coefficient of friction — it's the industry rating for how slip-resistant a tile is when wet. It matters most on bathroom and shower floors, where a glossy, low-DCOF tile that looks great in a showroom can be genuinely dangerous once it's wet underfoot. Ask about a tile's DCOF rating before choosing it for any floor that regularly gets wet.
Is a more expensive tile actually better?
Not necessarily — price often reflects material (natural stone costs more than porcelain), origin, and design exclusivity more than durability. A well-made porcelain tile can outperform an expensive natural stone tile in a high-traffic area, since porcelain resists moisture and wear better than most stone. The right tile fits the room, not the one with the highest price tag.
Showers, tubs & waterproofing
What waterproofing do you use in a shower?
{{PLACEHOLDER: waterproofing system used}} — a continuous membrane that goes behind and under the tile, not a coating that relies on grout to keep water out. Since grout is porous and breaks down with age, the membrane underneath is the part actually doing the waterproofing job. See shower tile installation for more on how it's applied.
Why do showers leak?
Almost always because water got behind the tile and had nowhere to go — either the waterproofing membrane was skipped, installed incorrectly, or never extended to cover niches, benches, and the pan edge. Grout is not waterproof on its own. By the time a leak shows up as a stain or soft flooring outside the shower, it's usually been happening for months.
Can you convert my bathtub into a walk-in shower?
Yes — DGJ handles full tub-to-shower conversions, which change the plumbing, framing, and waterproofing, not just the tile. It's one of the most requested upgrades in older homes with a garden tub nobody uses. See shower tile installation for what the conversion involves, or bathtub surround tiling if you're keeping the tub instead.
What is a curbless shower and can my bathroom have one?
A curbless shower sits flush with the bathroom floor, with no step or lip to keep water in — it needs enough floor depth to slope to the drain without a curb, which isn't possible in every bathroom without extra framing work. A linear drain often makes it more achievable, since it lets the floor slope in one direction instead of four. Ask during your estimate whether your bathroom qualifies.
Do I need a niche in my shower?
Not required, but it's a popular addition — a niche built into the wall gives you a permanent spot for soap and shampoo instead of a wire caddy hanging off the showerhead. It has to be planned into the framing and waterproofed as part of the wall system before tile goes on, not added as an afterthought once the shower is otherwise finished.
How long before I can use a new shower?
Grout and caulk both need time to cure before a shower sees regular water and steam — rushing that step is a common way a new shower ends up with cracked grout or a caulk line that fails early. Your installer should give you the exact cure window for your job, since it varies by product and conditions, not a fixed number that applies to every shower.
What's the difference between a shower pan and a mud-set floor?
A shower pan is often a pre-formed base (sometimes foam, sometimes fiberglass) that's set into place; a mud-set floor is built on-site from a sand-and-cement mortar bed, sloped by hand toward the drain. Both need a proper pre-slope underneath the waterproofing — the material changes, but the requirement to slope water toward the drain doesn't.
Kitchens & backsplashes
Do I need to remove my countertop for a new backsplash?
No, in most cases — the backsplash tile sets on the wall above the counter, and the countertop itself stays in place and gets protected during the job. Your estimate will flag it if your specific layout needs anything different, but a standard backsplash job doesn't require pulling the counter.
How high should a kitchen backsplash go?
Standard height runs from the counter to the bottom of the upper cabinets, typically an 18-inch band. Full-height carries the tile all the way up to the underside of the cabinets or ceiling, especially common behind a range. Either works — see kitchen backsplash installation for the full breakdown of the trade-offs.
Can you tile over my existing kitchen floor?
Usually not recommended — old flooring can hide subfloor problems, and tiling over it adds height that throws off transitions, appliance fit, and cabinet toe-kicks. Most installers, DGJ included, remove the old floor first. See kitchen tile installation for more on subfloor prep, or ask during your estimate whether your floor is an exception.
What grout should I use behind a stove?
Any grout works behind a stove in terms of heat — normal cooking heat isn't enough to damage cementitious or epoxy grout. The bigger factor is stain resistance, since that's the area that takes the most grease and splatter in the kitchen. Epoxy grout resists staining better than standard grout, though at a higher material and installation cost.
Do you tile under kitchen appliances?
{{PLACEHOLDER: appliance moving/tiling scope}} As a general rule, tile runs underneath a range or refrigerator that can be pulled out and replaced later, and stops at the front edge of a built-in, boxed-in dishwasher, since that one isn't going anywhere. Ask about your specific kitchen during your estimate.
Preparation, demo & aftercare
How do I prepare my home before a tile job starts?
Clear the room of anything breakable or in the way — furniture, wall decor, items in cabinets near the work area — and make a plan for pets during the loudest parts of demo. DGJ handles protecting the floors and pathways to the job site, but the fewer personal items in the immediate work zone, the smoother the first day goes.
Do you handle demo and haul-away of the old tile?
{{PLACEHOLDER: demo and disposal policy}} This gets confirmed in writing as part of your estimate, so you know exactly what's included in your price before demo starts — not as a surprise added on once the old tile is already out.
Will tile installation damage the rest of my house?
It shouldn't, if it's done properly — floors, doorways, and stairs along the path to the job get covered before demo starts and stay covered until the job's finished, not just the room being tiled. Ask any installer directly how they protect the rest of your home; it's a fair, standard question to ask before work begins.
How do I clean and maintain new tile?
Regular sweeping and a pH-neutral cleaner are enough for most tile — avoid vinegar or other acidic cleaners on natural stone, since they cause etching over time. Grout should be sealed after it cures and resealed periodically, since it's porous by nature and will absorb stains without that protection. Beyond that, tile is one of the lower-maintenance surfaces in the house.
Why does tile crack after installation?
Usually one of two causes: the substrate underneath wasn't flat or stable enough, or a movement joint was skipped where the tile meets another surface or spans a long run. Tile itself is rigid, so if what's underneath flexes even slightly, or there's no flexible joint to absorb normal building movement, the stress eventually shows up as a crack.
Can you tile over a cracked subfloor?
No — a cracked or unstable subfloor has to be repaired or reinforced before tile goes on, not tiled over. Setting tile over a subfloor that's still moving just relocates the crack up into the new tile and grout, usually within the first year. This is exactly the kind of substrate check that should happen before any estimate turns into a scheduled job.
Working with us — service area, scheduling, warranty & payment
What areas do you serve?
DGJ works throughout Metro Detroit, based out of Macomb, MI — Macomb Township, Sterling Heights, Shelby Township, Clinton Township, Chesterfield, Washington Township, Utica, Warren, Rochester Hills, and Troy. See the full service area for details. If you're near the edge of that area, call and ask rather than assume you're out of range — most nearby addresses are still covered.
Are you licensed and insured?
{{PLACEHOLDER: licensing and insurance status}} Hiring someone to work inside your home is a big decision, and asking to see proof of license and insurance before anyone starts is a fair, standard question — ask for it directly when you book your free estimate, and expect a straightforward answer.
What's your warranty?
Every installation is backed by a written workmanship warranty — {{PLACEHOLDER: warranty length}}. Ask for the specific terms in writing as part of your estimate, so you know exactly what's covered before work is scheduled. A workmanship warranty covers the installation itself, not manufacturer defects in the tile material, which is typically covered separately by whoever made the tile.
How do I pay for my project?
{{PLACEHOLDER: accepted payment methods}} Payment terms — deposit, progress payments, or payment on completion — get spelled out in your written estimate before work starts, so there's no ambiguity about when payment is due or how much.
Do you offer financing?
{{PLACEHOLDER: financing options}} If financing matters to your decision, ask about it directly during your estimate — it's a normal question, and you should get a clear answer before committing to a project, not a vague answer once work has already started.
How do I get started?
Call, text, or fill out the free estimate form with a few details about your project. Dervin will reach out to schedule an in-person visit, walk your space, and give you a real, written number — no pressure, no obligation to hire. That's the entire first step; everything else follows from there.
