Laminate flooring lasts 15 to 25 years at the AC3 and AC4 grades most homes buy, based on aggregated lifespan data, and 5 to 15 years at the budget AC1 and AC2 grades. The AC rating is the single biggest predictor, because it measures the only part of a laminate plank that wears: a clear melamine layer, a fraction of a millimeter thick, over a printed photograph of wood.
| Grade | Plank thickness it usually comes in | Aggregated service life in a home |
|---|---|---|
| AC1 | 6–7 mm | 5–10 years |
| AC2 | 7–8 mm | 10–15 years |
| AC3 (most common residential spec) | 8–10 mm | 15–20 years |
| AC4 | 10–12 mm | 20–25 years |
| AC5 | 12 mm | 25+ years |
Those ranges measure wear. Most laminate floors are not taken out because they wore out. They are taken out because water reached the seams, the edges chipped, or the boards began to gap, and none of those failures reads the AC rating first. The rest of this page covers where a floor lands inside its range, what ends it early, what a repair costs against a replacement, and what each year of service costs on a typical $1,800 installation.
What the AC Grade Does and Does Not Buy
AC is an abrasion class from the European standard EN 13329. It rates the wear layer against abrasion, impact, staining and cigarette burns, and it is printed on the box by the manufacturer. The laminate installation cost page prices each grade and explains why the rating is a self-declaration rather than a US certification.
The grade sets the ceiling on how long the surface holds out against grit. It does not set how long the floor stays down. An AC4 plank in a bedroom will almost never wear through in 25 years; the same plank in front of a dishwasher can be gone in six, because the aluminum-oxide surface that resists abrasion sits on a high-density fiberboard (HDF) core, and HDF is compressed wood fiber. Abrasion resistance and water resistance are separate properties, and the AC scale measures only the first.
Thickness is a separate lever, and it works on the joints rather than the surface. A 12 mm plank does not wear more slowly than an 8 mm plank of the same grade. What the extra millimeters buy is a deeper click profile, stiffer boards that bridge small dips in the subfloor, and less of the hollow sound thin laminate makes underfoot. Those matter for lifespan indirectly: a thin plank over a subfloor that is out of the common 3/16-inch-in-10-feet flatness tolerance flexes at every seam, and a flexing seam opens, chips and lets water in years before the surface shows wear.
Where a Given Floor Lands: Room by Room
A published range is a spread across homes, not a forecast for one room. The same AC3 floor sits at the top of its range where traffic is light and dry, and at the bottom where grit and water arrive together. Placed by room, the aggregated figures read like this:
| Room | What tests the floor | Standard AC3 laminate | AC4, or a waterproof-rated line |
|---|---|---|---|
| Bedroom, guest room | Light traffic, furniture feet | ~20 years, the top of the AC3 range | 25 years or more; the extra grade is rarely tested |
| Living and dining rooms | Furniture, sun through windows, a lane to the sofa | 15–20 years | ~20–25 years |
| Hallway, entry | Grit off shoes, wet boots, one narrow lane | ~15 years, the bottom of the AC3 range | ~20 years |
| Kitchen | Dropped pans, sink splashes, the dishwasher line | Set by the first water event rather than by wear | Longer between spills, same exposure to a leak |
| Basement over a slab | Vapor from below, occasional seepage | 5–15 years even when dry, per the basement flooring guide | Waterproof core only |
| Full bathroom | Standing water, humidity | Standard laminate is not rated for it | Most manufacturers rate waterproof lines for it |
| Stairs | Impact and wear on the front edge of each tread | Shortest life in the house; the nosing pieces go first | Same weak point |
The bedroom and hallway columns are the top and bottom of one aggregated range, not separate measurements. Two things stand out. First, the gap between grades is widest where traffic is heaviest: in a bedroom AC3 and AC4 both outlast the room’s decor, while in an entry the extra grade is worth roughly five years. Second, in the kitchen, basement and bathroom the grade stops being the deciding number, because a single leak outruns any wear rating.
Stairs deserve a separate note. Laminate on stairs is priced per step, commonly $60 to $150, and each tread carries a separate stair-nose piece that takes the full impact of every footstep. The nosing is where stair laminate fails first, and it cannot be re-sanded or re-edged.
Why Laminate Floors Actually Get Replaced
Laminate is unusual among floors in that it has no renewal step. Hardwood is sanded and refinished 4 to 6 times over its life; tile gets regrouted; carpet gets cleaned and restretched. Laminate’s wear layer is too thin to sand, and there is no product that restores it: the published care terms of one major laminate maker exclude damage from waxes and polishes outright. Whatever happens to a laminate floor is permanent, and the floor ends when enough of it has happened.
| Failure | What it looks like | What causes it | Does it end the floor? |
|---|---|---|---|
| Seam swelling | Raised, rounded plank edges; a “picture frame” around each board | Water sitting at the joints and wicking into the HDF core | Yes, when it spreads; swelling does not reverse on drying |
| Edge and corner chips | Pale, flaking chips along the plank edges | Dropped objects, flexing seams, beveled edges catching grit | Only when spread across a room |
| Wear-through | The printed grain fades to a pale patch in a traffic lane | Grit abrading the wear layer, faster on low AC grades | Yes, the print cannot be restored |
| Scratches | Fine lines, visible in raking light | Grit under shoes and chair legs, pet claws | Rarely; a cosmetic complaint more than a failure |
| Fading | A lighter patch in the shape of a window | Ultraviolet light on the decor layer | Only if the floor is rearranged and the patch shows |
| Gapping and peaking | Open joints in winter, boards tenting upward in summer | Humidity swings, a missing expansion gap, a floor pinned under cabinets or trim | Often fixable; persistent peaking breaks the locking joints |
| Hollow or soft spots | A dull sound or a dip underfoot | An uneven or deteriorating subfloor | Fixable only by lifting the floor |
Water is the failure that ends floors ahead of schedule. Grit wears a laminate floor over decades; a supply line ends it over a weekend. Once water has sat at the joints for 24 to 48 hours, swelling in the HDF core becomes permanent, and the water damaged floor repair data treats laminate in that state as a total loss, at $900 to $3,200 per room for the replacement floor before drying and subfloor work are added. That is why the room table above stops quoting years for the kitchen: in a room with a sink, a dishwasher and a refrigerator line, the floor’s life is set by the first leak nobody sees in time.
Chips are the second most common reason, and they are related to the first. A chipped edge exposes the core, and an exposed core is where a mop’s worth of water gets in. Beveled-edge laminate is more exposed than square-edged planks: one published warranty reviewed for this page does not count wear along a beveled edge within 3/16 inch of the plank’s side as wear at all.
Repair or Replace: Where the Dollar Line Falls
Because a floating laminate floor clicks together edge to edge, most repairs are possible, but they are priced by how far the damaged board sits from a wall rather than by the size of the damage.
| Damage | Repair path | Aggregated cost |
|---|---|---|
| A few scratches or a small chip | Color-matched filler or a touch-up marker | A DIY item; a pro visit for this alone is billed at the $150–$400 minimum job charge |
| One to a few damaged planks | Unclick the floor from the nearest wall back to the damaged board, swap it, re-click | $150–$450 per incident |
| Peaking from a floor pinned at the edges | Pull trim, re-cut the expansion gap around the perimeter | Typically inside a $150–$400 minimum charge on a small area |
| Swelling across a room after a leak | Tear out and replace | $900–$3,200 per room for the floor, plus drying and any subfloor work |
| Worn-through traffic lanes across a room | Tear out and replace | Tear-out at $1–$2 per sq ft plus a new installation |
| Damage to a discontinued pattern | Repair only from spare planks kept at installation | Keeping 5–10% extra costs about $35–$70 on 400 sq ft at a typical $1.75 per sq ft |
A single plank swap costs about 6 to 19 percent of a typical replacement cycle on a 400-square-foot room: $1,800 for the installation plus about $600 to tear out the old floor at $1.50 per square foot, the middle of the $1 to $2 per square foot floor removal rate. Repair is the cheaper path while damage stays localized and matching planks exist. It stops being cheaper when the damage is spread across the room, which is exactly what water and worn-through lanes do.
The spare-box line is the smallest number on the page and the one that most often decides whether a floor gets repaired or replaced. Laminate patterns turn over, and a replacement plank bought years later in “the same” color rarely matches the dye lot or the texture of the original.
What One Year of Laminate Floor Costs
Installed price and service life only mean something divided into each other. The table uses a 400-square-foot room at $3, $4.50 and $8 per square foot installed, the bottom, typical and top of the national installed range, and adds about $600 of tear-out at the end of each floor’s life, since every replacement starts by removing the last one.
| Tier | Installed + eventual tear-out | Per year at the short end of its range | Per year at the long end | Years needed to match a typical floor at 20 years ($120/yr) |
|---|---|---|---|---|
| Budget, AC1–AC2 (5–15 years) | $1,200 + $600 = $1,800 | $360 at 5 years | $120 at 15 years | 15, the very top of its range |
| Typical, AC3 (15–20 years) | $1,800 + $600 = $2,400 | $160 at 15 years | $120 at 20 years | — |
| Premium, AC4–AC5 (20–25+ years) | $3,200 + $600 = $3,800 | $190 at 20 years | $150 at 25 years | about 32 |
Three results come out of the arithmetic.
- The budget floor ties the typical floor only in a bedroom. At 15 years a budget floor costs the same $120 a year as a typical floor at 20. Anywhere busier than a guest room, it lands toward 5 to 10 years, or $180 to $360 a year.
- The premium tier does not pay back through years alone. At $8 per square foot installed it needs about 32 years of service to match a typical floor at 20, and no laminate grade is rated for that in a home. What the top of the range buys is feel, sound, texture and often a waterproof core, not a lower cost per year.
- The grade upgrade on its own is the cheaper way to buy years. Moving the plank from AC3 to AC4 adds about $0.50 to $1.50 per square foot in material, or $200 to $600 on 400 square feet, with no change in labor. In a hallway where AC3 lands near 15 years ($160 a year), an AC4 floor lasting 20 costs $130 to $150 a year.
Water rewrites the whole table. A typical $2,400 cycle ended by a dishwasher leak in year 6 costs $400 a year, more than the budget floor at the bottom of its range, and the replacement bill arrives on top of it. The long-run comparison across every floor type, including hardwood’s renewal cycles, is on the most durable flooring page.
Labor makes up most of every replacement cycle, both the installation and the tear-out, so the cost of each year moves with local wages. City figure = national figure × the city labor adjustment factor, applied to the labor share only:
| City | Labor Adjustment Factor | New AC3 floor, 400 sq ft | Replacement cycle incl. tear-out | Cost per year over 20 years | vs. National |
|---|---|---|---|---|---|
| Portland, OR | 1.15 | $1,965 | $2,655 | $135 | +15% |
| Los Angeles, CA | 1.14 | $1,955 | $2,640 | $130 | +14% |
| Dallas, TX | 0.89 | $1,680 | $2,215 | $110 | −11% |
| Nashville, TN | 0.93 | $1,725 | $2,280 | $115 | −7% |
| Miami, FL | 0.91 | $1,700 | $2,245 | $110 | −9% |
| Austin, TX | 0.95 | $1,745 | $2,315 | $115 | −5% |
Typical 400 sq ft laminate room: plank material held at the national figure, installation and tear-out labor scaled by the metro factor. The last column spreads the full cycle over a 20-year service life.

Standard, Water-Resistant and Waterproof Laminate in Wet Rooms
The label on the carton describes how the floor handles water, and three tiers are sold under the same “laminate” name:
- Standard laminate has a bare HDF core and plain click joints. Spills wiped up promptly do no harm; water left at the seams swells the core.
- Water-resistant laminate seals the core edges and tightens the joints, and states its tolerance in hours, such as the “24 hour water resistant” entry tier on one major brand’s line.
- Waterproof laminate takes one of two routes: a core of PVC or stone-polymer composite, at which point the plank is physically close to vinyl plank, or an HDF core protected from above with sealed joints and a waterproof surface. The best waterproof flooring page ranks every floor type by what a leak costs.
The step from standard to waterproof adds about $0.50 to $1.50 per square foot in material. On a 150-square-foot kitchen, that is $75 to $225, against $900 to $3,200 to replace the floor after a water event. The wear rating does not change: a waterproof AC4 plank carries the same 20 to 25 year wear life as a standard one. What it changes is whether an ordinary spill is survivable.
It does not make a leak survivable, and the warranties say so. Two published laminate warranties reviewed for this page, both for lines marketed on their water protection, cover moisture from everyday household spills, and both list flooding, standing water, leaking pipes, mechanical failures and appliance leaks as outside coverage, along with moisture that reaches the floor from underneath. The event that ends laminate floors in kitchens is the event those terms exclude. For rooms where a supply line or a slab is the exposure, the trade-off against vinyl plank, whose core does not absorb water at all, is laid out in laminate vs vinyl plank flooring cost.
Warranty Terms Next to Years in Service
“Lifetime warranty” appears on a large share of mid-range and premium laminate, and it describes something narrower than a floor that lasts a lifetime. The two warranty documents below — Pergo Portfolio + WetProtect and Mohawk RevWood Plus — were read in full; the wording in the table is theirs, summarized.
| Term | Pergo Portfolio + WetProtect (terms dated December 2018) | Mohawk RevWood Plus (terms dated March 2020) |
|---|---|---|
| Residential term | Limited lifetime, for as long as the original purchaser owns the flooring | Limited lifetime, to the person named as buyer on the purchase documents |
| What counts as wear | The laminate surface wearing through, readily visible over about 1 square inch | The wear layer wearing through the design layer, at least 0.5 square inch per plank; wear within 3/16 inch of a beveled edge excluded |
| Proration | Not stated | Full material credit years 1–6, 90% years 7–10, then falling each year to 40% in year 15 and 10% in year 20 |
| Water | Wet mopping and everyday household spills covered; flooding, standing water, leaking pipes, appliance leaks and water beneath the floor excluded | Waterproof system warranty for normal use; flooding, standing water, leaking pipes, appliance leaks and trapped moisture excluded |
| Physical damage | Scratching, impact, cutting, beater bars, steamers excluded | Scratches from dragging furniture, severe impact, cutting excluded |
| Remedy | Repair or replace the material; reasonable labor if professionally installed | Repair or replace the defective area; reasonable labor if professionally installed |
| Transfer | Not transferable | Applies to the named buyer only |
Read side by side, the documents describe the same product: a wear layer that almost never wears through in a home, warranted for life, and a floor that is replaced for reasons on the exclusion list. The proration schedule is the clearest statement of how the manufacturer itself values the years. By year 20, near the long end of an AC3 floor’s aggregated range, the lifetime warranty in the second document credits 10 percent of the material. Neither term transfers to the next owner of the house.
How Long Pergo Laminate Lasts
Pergo is a brand name, not a grade, and it covers two different floors. Its laminate lines, such as TimberCraft, Outlast+ and XP, have an HDF core and follow the laminate ranges above; its DuraCraft and Extreme lines are vinyl plank and follow vinyl ranges instead.
On the laminate side, the Lowe’s listing sampled for the Pergo vs SmartCore comparison showed 29 of 40 AC-rated Pergo laminate products at AC4 and 11 at AC3, and 33 of 50 at 10 mm thick. By grade, that places most of the Pergo laminate shelf in the 20 to 25 year band for wear, with AC3 products at 15 to 20. The same caveat applies as to any laminate: 44 of the 50 were tagged waterproof, and the Pergo warranty above is typical in covering spills while excluding leaks. The comparison page prices Pergo laminate at about $4.20 to $6.30 per square foot installed.
Laminate Among the Other Floors
Laminate’s 15 to 25 years sits in the middle of the residential field. Vinyl plank covers a similar span, 10 to 20 years at the 12 to 20 mil wear layers most homes buy, as broken down in how long LVP flooring lasts and on the laminate vs vinyl plank comparison, with the difference coming down to water (vinyl wins) and scratches (laminate wins). Wall-to-wall carpet runs shorter, as the carpet lifespan guide sets out by fiber, and solid hardwood runs 50 to 100 years because it can be sanded back to new, at several times the upfront cost of hardwood installation. Laminate’s advantage is the entry price; it is one of the cheapest flooring options that reads as wood. Its limit is that nothing renews it.
What Keeps Laminate in Service Longer
The measures below act on the specific failures in the table above. Most cost little, and several are conditions in the published warranty terms, which ties them to whether a claim is honored as well as to how long the floor lasts.
- Walk-off mats at exterior doors, $30 to $150. Grit is the abrasive that wears through the print in a traffic lane; both warranties above name entry mats or sufficient transition areas.
- Felt pads under furniture and soft rubber casters on chairs. Dragged furniture and hard casters are excluded from warranty coverage and are the usual cause of scratches in dining areas.
- A dry or damp mop, never a wet one or a steam mop unless the line is rated for it. Standing water at the seams is the core-swelling mechanism in miniature, and one of the warranties excludes steamers and beater bars outright.
- Stable indoor humidity and an intact expansion gap. Gapping in winter and peaking in summer come from the floor moving; the gap at the walls is what lets it move without breaking the joints.
- Blinds or UV-filtering film on sun-facing windows. Fading is the one kind of wear that needs no traffic.
- AC4 in halls and entries, $200 to $600 on 400 square feet. The cheapest way to add years where abrasion is the limiting factor.
- A waterproof-rated line in kitchens and laundry rooms, $0.50 to $1.50 per square foot extra. It survives spills; the leak exclusion above still applies.
- A spare carton or two, set aside at installation. It is what makes a $150 to $450 plank swap possible in year twelve.
