Floors Are Only as Good as What's Under Them
The difference between a floor that lasts twenty years and one that clicks, gaps, and peaks by spring is almost always the prep: a flat, dry, solid subfloor and the right underlayment for the room. We check and fix that layer first — leveling low spots, screwing down squeaks, replacing soft sections — before the first plank or tile goes down.
We install every common residential flooring: porcelain and ceramic tile, luxury vinyl plank and sheet vinyl, solid and engineered hardwood, laminate, and carpet. We also do the repairs most flooring stores won't: patching a burned spot, re-stretching a rippled hallway, replacing a cracked tile, or weaving new boards into an old fir floor.

Floor Repair or New Flooring: Cracked Tile, Damaged Planks and Soft Spots
Most floor damage is a spot repair, not a new floor. A cracked tile comes out with its grout and a new one goes in. A gouged click-lock plank is swapped by unclicking rows from the nearest wall, or cut out and replaced with a glued-in piece. A burned hardwood board is cut out and a new one woven in, and a carpet burn gets a patch cut from a remnant or the back of a closet. Matching is the hard part. Keep leftover cartons, because a discontinued plank or tile is hard to match, and on an old oak or fir floor, boards harvested from a closet match best.
A repair becomes a replacement when the problem is underneath. A soft spot beside the toilet usually means a slow leak rotted the subfloor, a spongy entry often means years of snowmelt got past the threshold, and tiles that keep cracking along one line mean the floor flexes.
Rotted subfloor gets replaced before any flooring goes down, and the plank subfloors and settled, out-of-level floors in many older Duluth and Superior homes need flattening first. Your written price lists tear-out, subfloor work and trim alongside the flooring. A rotted bathroom floor can turn into a bathroom remodel, and a basement slab needs the moisture checks covered under basement finishing.
When Flooring Is Installed in New Construction or a Remodel
In new construction and big remodels, flooring goes in late, after the messy trades are gone. The usual order is framing and rough-ins, insulation, drywall hung and finished, then primer and the first coat of paint on walls and ceilings. Hard flooring follows: tile, hardwood, LVP or laminate. Interior doors, casing and baseboard go on next, so the trim covers the expansion gap at the walls, and the final paint coat and trim touch-ups come after that. Carpet goes in last of all, once the baseboard is painted, because it's the easiest floor to ruin with drywall dust, paint drips and work boots.
Cabinets are the one real fork in that order. Tile, sheet vinyl and glue-down floors can run wall to wall with cabinets set on top, which keeps the dishwasher opening at full height. Floating floors can't: Mohawk's click vinyl instructions say not to install cabinets on top of it (Mohawk), so the cabinets go in first and the planks stop at the toe kick with an expansion gap. Protect a finished floor with rosin paper or a breathable floor protector while the last trades finish, and keep leftover cartons for repairs.
Flooring Across the Twin Ports
Twin Ports flooring work runs from vinyl plank and tile to hardwood, laminate and carpet, with the subfloor repaired first where it squeaks, dips or has been wet. Duluth's older houses and Superior's frost-shifted ones rarely have a flat subfloor, so the quote lists floor prep as its own line.
Send a photo of the room, its approximate size and the current floor, and tell us whether you have bought the flooring yet.
Repair, Replace or Call a Specialist? Flooring Decisions
Floors usually fail from what's beneath them. Read the symptom first, because a new floor over a wet or soft subfloor only hides the problem.
| What you're seeing | Likely cause | Usual fix | Who handles it |
|---|---|---|---|
| Floor squeaks when you walk | Boards or subfloor moving on joists | Screw down from above or below, shim gaps | Us |
| Cracked tile or loose grout | Flexing floor or failed adhesive | Replace tiles, regrout, stiffen the base if needed | Us |
| Vinyl or laminate planks buckling | Moisture, tight edges or temperature swings | Find the moisture source, then reinstall or replace | Us after the source is dry |
| Soft or spongy spot under the floor | Rotted subfloor from a leak | Fix the leak, cut out and replace subfloor | A plumber first if it's pipes; then us |
| Old vinyl or tile in an older home | Possible asbestos in old flooring or adhesive | Leave it alone until it's tested | A licensed abatement firm if tested positive |
| Floors sloping or cracking across a room | Joist, beam or foundation settlement | Evaluate structure before laying any new floor | A foundation specialist or engineer |
Floors That Survive Boots, Salt & Sand
Northland entries live a hard life — road salt in January, beach sand from Park Point in July, and wet boots for six months straight. We'll steer you honestly on what holds up here (porcelain and quality LVP at the entries, anything you love further in) and detail thresholds and transitions so meltwater doesn't find its way into your subfloor.
Flooring in Duluth, Superior and Nearby Towns
Laying a new floor needs no permit in Duluth, Superior or the Minnesota cities around them; the differences by place sit underneath and around the floor. Older houses bring out-of-level floors and old vinyl that should be tested before it comes up, Superior’s clay makes basement moisture the first question, and lake cabins that go unheated in winter run into the temperature rules in the flooring makers’ own instructions. Subfloor and joist repairs are where permits come back in. Here is how that plays out by place.
Flooring Installation in Duluth, MN
Duluth exempts tiling, carpeting and similar finish work from building permits (City of Duluth), and its permit FAQ lists floor coverings among work that needs none (City of Duluth). The same FAQ requires permits for structural alterations, so a floor job that turns into sistering joists or rebuilding framing under a bathroom becomes a permit item. That usually shows up only once the old floor is off, so the written quote says what happens if tear-out finds damaged framing, and we check what your address needs before the work is scheduled.
Age is the bigger factor here. About 43% of Duluth’s homes were built before 1940 (U.S. Census Bureau ACS 2020–2024, via Census Reporter), and in West Duluth a large share likely predate 1939 (Wikipedia). Houses that old often hide wood floors under carpet and several layers of vinyl, and settled framing that needs flattening before a click floor, since Mohawk’s rigid vinyl instructions require unevenness over 3/16 inch in 10 feet to be leveled (Mohawk). Old vinyl tiles, sheet-vinyl backing and adhesives are on EPA’s list of materials that may contain asbestos (EPA), so they get tested before anyone pulls them.
Flooring Installation in Superior, WI
The City of Superior lists new or different floor coverings, floor and wall tile, cement board under tile, and subfloor or underlayment 1/4 inch thick or less among work that needs no permit, along with sealing or coating interior concrete floors (City of Superior). Thicker subfloor work isn’t on that list, so replacing rotted 3/4-inch sheathing beside a toilet is worth a call to the building inspection office first. Superior’s housing is old enough for layered floors: 36% of homes predate 1940 (U.S. Census Bureau ACS 2020–2024, via Census Reporter), which also means testing old vinyl before it comes up.
Basements are the other Superior question. The red clays in and around the city are poorly drained (Wisconsin DNR), and that decides the product. Pergo’s laminate guide rules out any room with a floor drain and any floor level with a sump pump (Pergo), which excludes laminate from many basements outright, and Mohawk strongly recommends a 6-mil polyethylene vapor barrier under floating vinyl on concrete (Mohawk). Waterproof vinyl plank or tile over a tested, dry slab is the usual answer below grade.
Flooring in Hermantown, Proctor and Rice Lake
Hermantown, Proctor and Rice Lake each enforce the Minnesota State Building Code through their own offices (Minnesota DLI), and the code exempts tiling, carpeting and similar finish work from permits (Minn. R. 1300.0120). The houses split by age. Hermantown’s median home dates from 1993, while Rice Lake’s dates from 1972 and Proctor’s from 1968 (U.S. Census Bureau ACS 2020–2024, via Census Reporter).
In a Hermantown house the job is often replacing a first-generation floor. In Proctor and Rice Lake, at least half the homes date from 1972 or earlier, so sheet vinyl or tile from that era may be under the current floor and gets tested before removal (EPA).
Flooring in Cloquet and Moose Lake
Moose Lake spells it out: carpet, vinyl and wood flooring need no permit, but finishing a basement does (City of Moose Lake), so a new basement floor as part of a finished room is a permit job there.
In Esko and Harney, the Town of Thomson requires permits for structural work (Town of Thomson), and Cloquet requires them for structural changes (City of Cloquet), so joist repairs found under an old floor go through the local office. The October 1918 fire destroyed much of Cloquet (Wikipedia), and 27% of its homes date from before 1940 (U.S. Census Bureau ACS 2020–2024, via Census Reporter), so floors there often carry decades of layers.
Flooring in the Village and Town of Superior
On the Wisconsin side outside the city, the office depends on the government. The Village of Superior and Oliver handle their own permits. In the Town of Superior and Parkland, around Anton, Riverview and South Range, Douglas County’s fee schedule lists basements and enclosed living space among the additions and alterations that need a county land use permit (Douglas County), and the town’s own inspector issues any building permit (Douglas County). New flooring in an existing room isn’t on that list, but a floor that is part of turning a basement into living space is.
Flooring for Lake Cabins: Fredenberg, the Shore and Wisconsin Lakes
Seasonal places change the product choice more than any permit does. Around the Fredenberg flowages, where about 29% of the township is water (Wikipedia), along the shore at Knife River and Larsmont, and at Lake Nebagamon and Solon Springs, many cabins are closed or barely heated in winter. Pergo Extreme says not to install it in seasonal porches or in rooms or homes that aren’t temperature-controlled (Pergo), and Mohawk’s rigid vinyl expects 55 to 85°F before, during and after installation (Mohawk). Check the product’s instructions against how the cabin is actually heated before the flooring is bought.
Every town sets its own rules for flooring work. The Minnesota and Wisconsin permit office lists show which office to call and what it exempts.
Getting a Flooring Quote and How the Job Runs
What to Send for a Flooring Quote
A few photos and rough measurements are enough to start a flooring quote. Take a wide shot of each room from the doorway, a close-up of the current floor and any damage, and a photo of each spot where the floor meets another room, a stair or an outside door. Tell us about soft spots, squeaks or past leaks, and whether you have spare pieces or already bought the new flooring. Call or text the photos, or send them through our quote form.
Before requesting a quote, include: Wide and close-up photos of each floor; Rough room sizes and every doorway or stair edge; The product name or box label, plus any spare pieces. If the list is long, use the repair-list planning guide to sort it first.
How a Flooring Job Works
- Send the details. Start with the quote form or a call to (715) 919-7956; photos of the spot help most for flooring.
- Get a flat written quote. The price arrives in writing for you to approve; if the job needs a look first, the $95 visit fee is waived once you approve the work.
- Pick a day. Work is booked for a day that suits you.
- Work done, then a walkthrough. We finish with cleanup and a walkthrough of the flooring work, and we guarantee the workmanship in writing, so a failure means we return and redo it at no charge.
Flooring Questions
Can you install flooring I already bought?
Yes. Installing flooring you bought yourself is a normal labor-only job for us. When it's delivered, check the boxes for damage and matching lot numbers, and order a little extra for cuts. Many makers want the material to sit in the room before it goes down, and we'll tell you how long yours needs. We install the floor; the product warranty stays with the manufacturer.
Do you move furniture and remove the old floor?
Yes, if you want them in the quote. Tear-out, haul-away and moving furniture out of the room and back are listed as separate lines, so you can handle any part yourself and see what it saves. Clear out small items, electronics and anything fragile before the visit. Old sheet vinyl, tile or adhesive in an older home may need an asbestos test first, done by a licensed abatement firm.
My floor squeaks like a haunted house. Fixable?
Almost always, and usually without replacing the floor. A squeak is movement: a board rubbing on a nail, or the subfloor lifting off a joist. We find each spot and fasten it down, from below with shims or blocking when the basement ceiling is open, or from above with screws made to hide under carpet or in hardwood. A soft or spongy spot is a different problem, and that's a subfloor repair.
How much does LVP flooring installation cost?
Our planning range for LVP installation is $3–$7 per square foot for labor. The flooring itself, tear-out, subfloor leveling, transitions and trim are quoted alongside it, so the written quote shows each part. Rooms with lots of cuts, such as a bathroom around a toilet and vanity or a hallway with several doorways, take longer per square foot than one open room. The cost guide has more planning ranges.
Should I install flooring myself or hire a pro?
Install it yourself if it's click-together LVP or laminate in a simple room on a flat, solid subfloor; hire it out for tile, nail-down hardwood, stairs, bathrooms where the toilet comes up, or old floors that are out of level. The planks are the easy part. Subfloor prep, undercutting door jambs and clean transitions are where DIY floors go wrong. Our planning range for LVP labor is $3–$7 per square foot, and we install flooring you've already bought.
Do interior doors go in before or after flooring?
Either can work if it's planned. With carpet, doors are hung first and the bottoms trimmed to clear it. With hard flooring, jambs are usually set at the finished floor height, and when doors are already in, the jambs and casing get undercut so the flooring slides beneath them; Mohawk's click vinyl instructions call for exactly that (Mohawk). Doors hung too low end up dragging on the new floor.
Do you have to remove baseboards to install LVP or laminate?
Not always. A floating floor needs an expansion gap at every wall, 3/8 inch in Mohawk's click vinyl instructions, which also make removing baseboard optional as long as quarter round covers the gap. Pulling the baseboard and reinstalling it after gives a cleaner look with no quarter round. Either way, trim is nailed to the wall, never down through a floating floor, or it pins the planks and they buckle.
How long does vinyl plank flooring need to acclimate?
As long as the maker says, and 48 hours is common. Mohawk's rigid click vinyl, for example, must sit in the room where it's going for 48 hours at 55 to 85 degrees Fahrenheit before installation (Mohawk). In a Duluth or Superior winter that matters: cartons carried in from a cold garage or truck need the full time, and the heat should stay on during and after the install. Check your product's instructions.
How long does flooring installation take?
A single room of floating LVP or laminate is usually a one-day job once the material has acclimated and the old floor is out. Add time for tear-out, subfloor repairs or leveling, and moving furniture. Tile takes longer, since mortar and grout need time to cure, so a bathroom tile floor often runs two or three days with the toilet reset at the end. A whole level of LVP is typically a few days. Dates and sequence are laid out in your quote.
When does a flooring job need a permit in Duluth or Superior?
Only when it's part of bigger work. Laying the floor itself needs none: Duluth lists tiling, carpeting and similar finish work among the projects that need no building permit (City of Duluth), and Superior's Permits Not Required list includes new floor coverings and floor tile (City of Superior). The bigger work that does need one includes a bathroom remodel with plumbing changes and structural subfloor or joist repairs.
Can you install vinyl plank flooring directly on the subfloor?
Yes, if the subfloor is flat, dry and solid, but it rarely goes down with no prep. Mohawk's rigid click vinyl instructions require any unevenness over 3/16 inch in 10 feet to be leveled, wood subfloors to read no more than 14% moisture, and strongly recommend a 6-mil polyethylene vapor barrier under floating floors on concrete. The same guide calls for a double-layer wood subfloor with an underlayment-grade top layer (Mohawk). In Duluth and Superior basements, the concrete moisture check matters most.
Where do you start when laying vinyl plank or laminate flooring?
In a corner, with the first row along a straight wall and spacers holding the expansion gap. Pergo's Extreme click flooring guide starts in a corner, staggers end joints at least 6 inches from row to row and keeps every end piece at least 8 inches long (Pergo). Mohawk's rigid vinyl starts the first row with a full-length plank (Mohawk). Your product's instructions also set the wall gap: 1/4 inch for that Pergo floor, 3/8 inch for the Mohawk.
Will vinyl plank flooring scratch?
It can. Vinyl plank resists scratches but isn't scratch-proof. Mohawk's care guide calls for floor protectors at least 1 inch across on chair, appliance and furniture legs and says to lift furniture rather than drag it (Mohawk), and its warranty requires walk-off mats at exterior doors to catch grit and deicers (Mohawk warranty). In a Twin Ports winter, road salt and sand carried in on boots are the biggest scratch risk at the entries.
What does a vinyl plank flooring warranty cover?
Manufacturing defects and wear-through, not installation mistakes or everyday damage. Mohawk's luxury vinyl warranty defines wear as complete loss of the wear layer so the printed pattern changes; gloss loss doesn't count. It excludes plumbing or appliance leaks, floods, moisture coming up from below and installs that don't follow its guide, and it covers only defects that weren't visible when the planks went down (Mohawk warranty). So inspect every plank before it's installed, keep the receipt and follow the instructions.
Is laminate flooring a bad idea?
Not in bedrooms, living rooms and hallways, where it's tough and budget-friendly. It's a bad idea where water can sit. Pergo's laminate installation guide says its floors must not go in a room with a floor drain, or anywhere on a level that has a sump pump, and that liquid shouldn't stand on the surface longer than 30 minutes (Pergo). That rules out many Duluth and Superior basements. For basements, bathrooms and laundry rooms, waterproof vinyl plank or tile is the safer pick.
Will new flooring increase my home's value?
Wood floors have the best numbers behind them. The National Association of Realtors' 2022 Remodeling Impact Report estimated that refinishing hardwood floors recovered 147% of its cost and new wood flooring 118% (NAR). Those are national estimates for wood, not laminate or vinyl plank. If an older home has oak or fir hiding under carpet, pull up a corner before pricing new flooring; refinishing may beat replacing.
Can new flooring go over my old floor?
Often, yes, if the old floor is flat, solid and firmly stuck down. Floating LVP and laminate can usually go over sound sheet vinyl or flat tile, which saves tear-out, but not over carpet, and loose, cushioned or water-damaged flooring has to come up. Height is the other limit, since each layer raises the floor at doorways, the dishwasher and the toilet. Before old vinyl comes up, have it tested: vinyl floor tiles, sheet-vinyl backing and adhesives are on the EPA list of places asbestos may be found.
These answers also sit in the Flooring section of our FAQ, alongside questions on pricing, scheduling and coverage.
