Eden Prairie Wood Flooring has spent more than twenty years installing, sanding and refinishing wood flooring in Mounds View, and the first thing we want to know here is never the species. It is what the floor is actually built on. A quote written without that answer is a guess dressed up in numbers.
This city carries more kinds of floor structure than a single suburb usually does. On one street a floor sits on joists and a plywood deck over a lower level; a few minutes away the same square footage sits on a manufactured chassis with decking that takes a fastener very differently. The installation method, the underlayment and the moisture test all change with that answer.
So the first visit is a measuring visit. We put a hygrometer in the room and write the indoor relative humidity down, we read the moisture content of the subfloor and of the flooring separately, and both numbers go on the paperwork before anyone talks about price.
A seventies suburb, and the floor that came with that decade
The 1970s are the single biggest decade in this city’s housing stock: 1,657 of 5,698 units, or 29.1 percent, were built then, and 3,570 units — 62.7 percent — predate 1980. That is not trivia when you are pricing a refinish. It means the floor under the carpet is roughly fifty years old, that it has been through fifty heating seasons, and that whatever was fastened down in 1974 has been moving ever since.
What fifty years does to a subfloor
Before we quote a sand-and-finish we walk the floor looking for what age produces rather than what abuse does: squeaks along the joist lines, nail pops that will telegraph through a new finish, and overwood at board ends where the deck has settled unevenly. Most of it is fixable, and fixing it first is cheaper than sanding around it.
The repairs that matter are unglamorous. A subfloor screw-down through the existing deck, occasionally joist sistering where a span has gone soft, sometimes a self-leveling underlayment in one room rather than across the whole floor. We price those separately so you can see what is floor and what is structure.
Sanding a floor in pre-1978 housing
Most of that seventies stock, and everything older, falls inside pre-1978 housing, so the federal EPA Renovation, Repair and Painting rule governs renovation that disturbs paint. Minnesota is not an EPA-authorized RRP state, which means the federal rule applies directly rather than through a state program.
In practice that shapes the setup more than the price. HEPA-shrouded sanders, containment at the doorways, and dustless sanding as the default rather than an upsell. Baseboards, shoe molding and stair risers are where old paint and a machine meet, so those are the areas we plan around first.
Selling the house: what the city actually checks
Sellers ask us constantly whether their floors get looked at before closing. They do not. There is no time-of-sale housing evaluation and no interior disclosure report required in this city at all, and the single point-of-sale requirement is Ordinance 967, administered by Public Works under the city’s Water Preservation Program.
That ordinance covers the sewer lateral and nothing else. The service line from the property to the sewer main must be televised before title transfers and, if defective, rehabilitated or repaired within 90 days, on a $150 application fee, with no floor or interior-finish line item anywhere in it. Refinishing before a sale is a market decision here, not a compliance one.

One home in thirteen here is not site-built at all
Of the 5,698 housing units in Mounds View, 425 — 7.5 percent — are mobile homes. Another 3,140 units, 55.1 percent, are single detached houses, and 1,732 sit in structures of two or more units. Roughly one home in thirteen is therefore not a site-built structure, which is why we never assume a joist span or a plywood deck before we have seen the address.
That assumption costs money when it is wrong. Basements are common across this part of the country, and full or partial basements accounted for 62.3 percent of new single-family homes started in the West North Central division in 2024, but a division-level figure is not a statement about your house.
Three parks, and the question we ask first
The city names three manufactured home communities: Colonial Village on Rustad Lane, Moundsview Manufactured Home Community on Montclair Avenue, and Townsedge Terrace on Old Highway 8. When an address sits in one of them, the conversation starts with the floor structure rather than with the finish.
It is not a harder job. It is a different one. The fastener spacing schedule, the underlayment and the realistic installation method all get decided from what the decking measures on site, not from what a floor of that size usually sits on.
Below grade, where there is a lower level
For the site-built homes with a finished lower level, the slab reading is the whole quote. We take it on the lower-level slab itself, with a calcium chloride test or an in-situ relative humidity probe run to ASTM F2170, rather than reading the floor above it and calling that close enough.
That number decides whether a below-grade installation needs a vapor retarder and what perm rating it has to carry, and whether an engineered floor is the honest recommendation instead of solid. Reading upstairs and quoting downstairs is how a lower-level floor cups in its second summer.
Floors people expect to keep
Owner occupancy runs 69.3 percent here, 3,726 of 5,379 occupied units, and it shows in what gets asked for. These are floors somebody plans to live on for another decade, so the real question is usually refinish versus replace rather than what is cheapest this month.
We answer it with a wear layer measured before an engineered floor is quoted for a refinish, and an honest read on a solid one. Past a certain thickness there is nothing left to sand, and we would rather say so at the quote than sell a sanding that ends in a sand-through.
What a manufactured floor structure will and will not take
A manufactured home is built on its own structure and the floor is part of it. What we measure on the first visit is deflection between supports, what the decking is made of, how much bite a fastener gets in it, and how much height the doorways and cabinet toe kicks can give up.
Those answers decide the method. A nail-down over decking that will not hold a cleat is a squeak you can hear within a year; a glue-down needs a surface the adhesive is rated for; a floating floor needs a flat plane and a real expansion gap at every wall, and on this kind of structure it is often the right answer rather than a compromise.
Flatness and height, before anything is ordered
Flatness gets corrected with a self-leveling underlayment or by sheeting over, and both cost height. We measure that before anything is ordered, so the transitions still work: a reducer at a doorway, a T-mold where two floating fields meet, a threshold at an exterior door that closes afterward.
That is the one mistake on this kind of floor that cannot be argued away later. A door that no longer clears, or a step up into a bathroom that was not there before, is a carpentry problem created at the quoting stage.
Who signs off on the work
The Minnesota Department of Labor and Industry regulates the construction and installation of manufactured homes themselves. Work on a manufactured home or its property is permitted by the city the same as any other single-family dwelling, with the added step that the park manager’s approval is typically required.
For ordinary finish work the permit question often resolves itself. Minnesota Rules 1300.0120 exempts tiling, carpeting, cabinets, countertops and similar finish work from a permit, while stating plainly that an exemption does not authorize work in violation of the code or other ordinances. The City of Mounds View Community Development Department issues permits directly, so when a job does need one there is no detour through the county.
Engineered cores, and what a wear layer buys
Engineered core construction shows up often on these floors for sound reasons: dimensional stability over a deck that moves, and a thinner profile where height is tight. The trade-off is the wear layer, and the wear layer is a finite number rather than an opinion.
If there is one sanding left in a floor, that is worth knowing before the quote is signed. If there is none, a screen-and-recoat can still buy years of service, and we will tell you which of the two you are actually looking at.
Forced-air heat, dry winters, and a fifty-year-old floor
In this metro 89.1 percent of owner-occupied homes heat with a warm-air furnace, and forced-air heating in January is what really drives a wood floor here. The NWFA performance band is 30 to 50 percent relative humidity at 60 to 80 degrees Fahrenheit, and a heated Minnesota house in midwinter sits below it, sometimes well below.
That is not an argument against wood flooring. It is an argument for knowing the numbers, because equilibrium moisture content follows the room, and a floor installed at one moisture content differential and then lived in at another will tell you about it.
The humidifier conversation, up front
A whole-house humidifier on a sensible humidistat setting is usually part of the answer, and we would rather explain the conflict than hand over a number. What the floor wants in January and what fifty-year-old windows will tolerate before they run with condensation are not the same setting.
So we say where the compromise lands, in writing, at the quote: what the flooring is specified for, what the house can realistically hold, and what that means you will see. A humidistat setting handed over without that explanation gets turned back down in February anyway.
Winter gapping is measured, not argued about
Seasonal gapping between boards is normal in a dry heating season, and a good share of it closes again by June. Before anyone calls it a defect we measure the gaps and photograph them, with the room’s relative humidity recorded alongside, so there is a documented before to compare against.
What that separates is the normal from the real. Dry cupping, crowning where a floor was sanded flat while it was still wet, and compression set where boards were laid tight through a humid stretch are different problems with different answers, and the measurement is what tells them apart.
The finish schedule, cure time and getting the house back
The quote carries a written grit sequence and finish schedule: a 36-50-80 progression where the floor calls for it, the abrasive screen before coats, the finish and the sheen level named. That way the work can be checked against something instead of taken on trust.
Cure time and dry time are different things, and both go in writing along with what a cool house in January does to them. Waterborne polyurethane and oil-modified polyurethane behave differently there, and a lower level behaves differently again. Before the first machine runs we plan where the furniture goes, where the pets go and where the household sleeps, because a floor nobody can walk on for a weekend is a scheduling question you should hear at the quote and not on the day.
