Flower Mound Wood Flooring installs and refinishes wood flooring in Justin, and we have spent more than twenty years doing it on North Texas slabs rather than learning the trade somewhere else and importing the habits. That experience shows up first in sequencing: we test a slab for moisture before an installation date goes on the calendar, not after the boards are stacked in the garage. It is a slower start and, almost always, a shorter job.
It also shows up in what we tell you before any work begins. If a screen and recoat will get your floor where you want it, we will say so rather than sell you a full sand, and the written scope you approve is the price — nothing gets discovered halfway through the second day.
Justin is one of the few places where that kind of discipline is written into the permit counter rather than left to the contractor’s conscience. A floor that turns out to be sitting on a foundation problem has a defined path here, and that path runs through a licensed engineer. Knowing it on day one changes what we quote and how we schedule.
When leveling stops being a flooring job
Most floors that feel uneven do not need structural work. The usual fix is concrete grinding on the high spots and self-leveling underlayment in the low ones, brought inside the subfloor flatness tolerance the manufacturer’s warranty depends on. But there is a line past which flatness work becomes foundation work, and in this city that line has paperwork attached to it.
The stamped plan, the compliance letter and the letter at the end
The City of Justin requires foundation repair to be designed by a state-licensed engineer. The permit takes an application, a complete set of foundation plans carrying an engineer’s stamp, and a letter from that engineer stating the plans were designed to and comply with the codes the city currently has adopted. A second engineer’s letter is required on completion.
That is a longer runway than most homeowners expect when they call about a floor. We would rather you hear it while the floor is still down than discover it after demolition, so if the first walkthrough points to movement instead of a surface problem, we say so and stop. Plan review runs ten business days through the city’s iWorQ online portal, and that time belongs in the schedule from the beginning.
Telling a flatness problem from a movement problem
The difference is a measurement, not an opinion. We take elevations across the slab, read what the door frames and trim reveals are doing, and check whether the deviation is a smooth dish or a sharp step. A shallow dish is ours to correct; a step that keeps moving is not.
Where a floor is going down over a repair somebody else is handling, we sequence around that work rather than through it. Laying boards over a slab that is still settling buys a callback in the first heating season, and no adhesive or fastener schedule rescues it.
Working inside the city’s hours and its code editions
Justin has adopted the 2018 IRC, 2018 IECC and 2018 ISPSC along with the 2017 NEC on the residential side, and we build to the editions the town has actually adopted rather than a generic national reference. Every contractor working here registers annually with the city, and we keep that registration current ahead of a job instead of at the permit window.
Permitted construction hours are weekdays from 7:00 a.m. to 6:00 p.m. and Saturdays from 8:00 a.m. to 6:00 p.m., with no Sunday work at all. That constrains a finishing job more than an install, because coating schedules live or die on cure windows and a Sunday cannot be borrowed to recover one. We lay out sanding and coating against the six days the city allows before we give you a finish date.

Sand over sandstone, and why the usual diagnosis does not transfer
Justin sits on the Eastern Cross Timbers, a belt that runs down out of Oklahoma through the central part of Denton County. Its soils are sandy or sandy loam derived from sandstone parent material, and they drain well. That is a materially different regime from the heavy calcareous alkaline clays farther east, and floor advice built on those clays does not carry over unexamined.
Less seasonal shrink-swell, a different moisture path
Well-drained sandy loam moves less through the year than a soil that swells and shrinks with every wet and dry cycle, so we generally see less of the slab movement that drives seasonal gapping, cupping and crowning in the clay country. What we watch here instead is where the water actually goes.
Water that drains readily still has to drain somewhere, and the path it takes under and around a slab is the thing worth establishing before a glue-down installation goes in. Grading, downspout discharge and irrigation run hard against the foundation tend to show up as a moisture reading long before they show up as a visible symptom.
Diagnosis by meter, not by region
A floor complaint diagnosed from a regional stereotype is a guess wearing a lab coat. We use a pinless moisture meter on wood and, on concrete, an ASTM F2170 in-situ relative humidity test or a calcium chloride test, depending on what the assembly and the adhesive manufacturer call for.
The number then decides the method. A slab reading high is a candidate for a vapor retarder and a floating installation rather than a glue-down, and we would rather change the method than gamble on the boards.
What the soil regime means for board choice
Moisture behavior feeds into what we recommend you put down. Wider plank widths and solid hardwood register a moisture swing more visibly than narrower boards or engineered hardwood with a thick wear layer, so the slab reading and the room’s daily use both belong in that conversation.
Past that it is preference and traffic. White oak, red oak and hickory all finish beautifully; hickory’s higher Janka hardness rating earns its keep in a house with dogs and a side door, while white oak takes a hardwax oil or a waterborne polyurethane more evenly than red oak’s stronger grain.
The original town grid, where no two houses match
Justin began in 1883 with the sale of town lots, and by 1896 it had a population of 100, a general store, a grocery, a hotel and a cotton gin. A century and a quarter on, 100 of the city’s 1,842 occupied housing units predate 1960, and 25 of those were built in 1939 or earlier. Most of them stand in and around that original grid.
A small pocket, and a real one
One hundred units out of 1,842 is 5.43% of the stock, which makes pre-slab-era construction a genuine but narrow category here rather than a safe regional assumption. In houses of that age, original strip flooring over joists, crawl-space moisture and deflection between joists are live possibilities we check for instead of generalities we recite.
It is also a small enough pocket that no two of these houses can be assumed to match. We do not carry a foundation type or a subfloor assembly from one address to the next, and we will not tell you what is under your floor before we have opened a corner and looked.
Repair depth on a floor worth keeping
An original floor with life left in it is usually worth more than whatever would replace it. Where damage is local, a weave-in repair or a dutchman patch with board replacement laced into the surrounding field disappears far better than a fresh seam across a doorway, and the original boards stay in the room.
Where the whole floor is tired, the ladder runs from a screen and recoat up to a full sand with a proper grit sequence. Drum sander, edger and buffer each do a distinct part of that, the sheen level you choose decides how much of the floor’s history it shows, and on old boards the standing question is how much thickness is left to give.
Dust, and living in the house while we work
Sanding an occupied older house is as much a containment problem as a finishing one. We run dustless sanding with containment and seal the rest of the house off from the work area, move furniture out and put it back, and leave the room clean at the end of each day.
One crew stays on the job from the first morning to the last, and the sanding is never handed to a subcontractor. On a floor that cannot simply be reordered, that continuity is the part that matters most.
New slabs that have not finished drying
The other end of Justin’s housing stock is very new. 87.46% of units were built in 1980 or later, the modal decade is the 2010s at 536 units, and 416 units — 22.6% of the stock — went up in 2020 or later. Timberbrook, the master-planned community planned at roughly 1,000 homes at build-out, was about 60% complete as of summer 2025, with a 1,550-home addition behind it.
Concrete dries on its own schedule
On stock that new, a slab has often not finished releasing moisture, and the calendar is not the test. We take a quantitative reading and treat that number as the go/no-go for any glue-down or floating install, which is exactly why the moisture test happens before an installation date is set.
A high reading is not a refusal, it is a change of plan: a different underlayment, a vapor retarder, another method, or a few more weeks. What we will not do is put boards down against a bad number and hope the room forgives it.
Acclimation and the details that hold a new floor together
Boards acclimate inside your house, not in the garage and not on the truck, and not one is fastened down until they have. We leave the expansion gap the assembly needs at every wall and vertical, and choose fasteners — cleats or staples at the right fastener crown width — to the subfloor we actually find rather than the one the plan assumed.
Transitions get the same attention, because they are where a fast job shows its seams. T-molding, a reducer and quarter round have to sit flush and stay flush, and stair treads, risers and stair nosing are the details a homeowner’s eye lands on every single day.
Owner-decided work in a detached-house town
91.86% of Justin’s housing units are single-family detached and 83.71% of households own their home, so the work here is almost entirely owner-decided: a kitchen and living-area upgrade, a stair run redone, a whole floor changed on taste rather than on a lease turnover. Only 114 units date from the 1990s, so the refinish-or-replace question tends to split cleanly between genuinely old floors and genuinely new ones.
That shapes how we quote. You get a written scope before anything starts and an honest read on the repair depth, and where a job began with water damage, you get the documentation a claim needs: dated photographs, moisture readings and an itemized scope.
