New Durham is an old town with a lot of dirt road in it, and those two facts land on the same tile floor. Grit scours the glaze, wood heat lays down a fine film over everything, and the grout lines take both because they sit lower than the tile.
This town was granted in 1749 as Cochecho Township, settled the next year by people coming up from Durham, and incorporated in December of 1762. By 1859 it was running five sawmills, four shingle mills, two gristmills and a gunpowder works — the Eureka — and the Cocheco Railroad had come through in 1849. Reverend Benjamin Randall founded the Free Will Baptists here in 1780. All of which is to say: there are floors in the village and out at New Durham Corner that have been walked on for a very long time.
Old floors mean small tile and a lot of grout. A 1920s bathroom with inch hex tile has more linear feet of grout line per square foot of floor than a modern kitchen with big-format porcelain does, and every one of those lines is porous cement sitting below the surface. Mop water runs into them and stays. Thirty years of that and the tile looks fine while the lines have gone two shades dark, evenly, everywhere — which is how you know it isn’t a stain but accumulated soil.
Then there’s the heat. Plenty of houses out here past the pavement burn wood or pellets as their real heat and not as ambience. That puts a thin oily soot into the air that settles on horizontal surfaces, so the kitchen and mudroom tile gets a film you can feel with a fingertip. It is greasy, not gritty, and mopping mostly spreads it around. Combine it with sand tracked off a dirt road in April and you have a floor that is being polished and dirtied at the same time.
If the mudroom tile feels slightly tacky rather than dusty, that’s wood-heat film, and a household floor cleaner is the wrong tool — most of them are neutral, and film needs something alkaline to break it. Don’t go at it with vinegar either, especially on stone.
Grout is cement. Cement is porous. That is the whole problem, stated plainly — a grout line is a narrow strip of absorbent stone sitting lower than the tile on either side, so everything liquid on that floor drains into it and soaks in. Mopping relocates dirty water into the low spot. It does not lift it out.
What we bring instead is an alkaline pre-treatment to break down the grease and soot film, then a pressurized rotary tool that injects hot water into the line and vacuums it straight back out under the same head, so nothing drains back down. Where there’s genuine mineral scale we switch to an acidic step for that part, because acid is what dissolves calcium — but never on marble, slate, or unglazed natural stone, where it etches the surface permanently and there is no undoing it. So we establish what the floor actually is before we choose anything. A surprising number of people have been told their floor is ceramic when it is honed stone.
Sealing after, if you want it. A penetrating sealer soaks into the grout and gives a spill a few seconds to be wiped up rather than absorbed. It wears off — two or three years in a mudroom that sees real winter, longer in a guest bath nobody uses. Anyone selling you a permanent seal is selling you something.
Tile and grout runs $1.50–$3.50 per square foot depending on how far into the lines it has gone; sealing is quoted per area on top of that. We measure the floor and hand you the flat number before anything gets wet. An old village bathroom is a short visit and priced like one.
Because mopping moves dirty water into the lowest part of the floor, which is exactly where the grout is, and porous cement absorbs it. Weekly mopping keeps the tile surface clean while slowly darkening the lines. It takes injection and simultaneous vacuum extraction to get soil back out of a grout line.
Not if we look first. Original grout in a ninety-year-old hex floor can be soft, and a tile that is already loose will get worse under pressure no matter who touches it. We check for hollow spots, dial the pressure down where we need to, and tell you what we found instead of working through it.
In a wood- or pellet-heated house it is almost certainly combustion soot — a fine oily residue that settles on flat surfaces. It is greasy rather than gritty, so a neutral floor cleaner just redistributes it. It needs an alkaline pre-treatment with enough dwell time to break the bond.
Often close. How close depends on whether the discoloration sits on the surface or has gone into the cement, and on whether bleach has already damaged it. We clean a test patch in a corner and show you the actual result before you commit to the whole floor.
No, and we will not pretend you do. Seal a mudroom or a bathroom floor where water lands daily. A dining room floor may not need it at all. If you sealed two years ago and the spills still bead up, you are fine for now.
