The Floor Is Only as Flat as whatever is underneath it
Hardwood, tile, vinyl, laminate and epoxy, installed over a subfloor that has actually been prepared. In a century-old rowhome that preparation is most of the work and all of the difference.
Preparation Is the Job
Rowhome floors are not flat. A hundred years of settlement, previous repairs and joists that have taken on a permanent set mean the subfloor you are covering almost never starts level. Install over that without correcting it and you get the same result every time: hollow spots underfoot, tile that cracks along a grout line, planks that separate at the seams.
So the first part of any flooring job here is finding out what is under the old covering — how flat it is, how sound it is, and whether previous layers left anything that has to come out.
Material choice matters just as much, and it is mostly a moisture question. Below grade rules out several popular options regardless of how they look in a showroom. If your project is a basement, see basement finishing for how the floor fits into the wider build.
Five Materials, Different Rules
They are not interchangeable. Where the floor is decides what belongs on it.
What Happens Before the New Floor Appears
Most of the value in a flooring job is delivered before the finished material is even opened.
We lift a section and look. Number of existing layers, condition of the sheathing, and how much the floor deviates from level all change the scope.
Below grade and on any concrete slab, moisture gets measured rather than assumed. This is what determines which materials are actually viable.
We tell you which options suit the room and which ones will fail there, then price the job including whatever preparation the subfloor needs.
Old covering and any accumulated underlayment out, down to a substrate we can actually work with.
Damaged sheathing replaced, joists sistered where necessary, then levelling compound or underlayment as the material requires.
The floor laid to the manufacturer’s requirements, with clean transitions at doorways and trim that finishes the edges properly.
Why the Cheap Quote Is Usually the Expensive One
The difference between quotes is almost always what has been left out of the preparation.
The preparation is in the price
A quote that assumes a flat, sound subfloor in a century-old rowhome is not a quote, it is an opening bid.
Material matched to the room
Moisture, deflection and traffic decide what belongs where. Getting this wrong is how a floor fails within a couple of years.
The subfloor gets repaired, not covered
Soft sheathing and deflecting joists are fixed. Laying new flooring over them transfers the problem to the new surface.
One contractor if there is more to it
If the floor is soft because of a leak, we can fix the plumbing and the framing too, rather than handing you a list of other people to call.
Flooring Questions
Basements, subfloors, going over existing flooring, and which material suits which room.
What flooring works in a Philadelphia basement?
Below grade, moisture is the deciding factor rather than appearance. Concrete slabs pass water vapour even when they look and feel dry, which is why solid hardwood and most laminates are poor choices down there regardless of how they look upstairs. Luxury vinyl is genuinely water-tolerant and is the practical answer for most finished basements. Tile works well over a properly prepared slab. Epoxy suits utility and workshop spaces. Before recommending anything we test the slab for moisture, because installing the wrong material over a damp slab produces cupping, lifting seams and eventually a floor that has to come out entirely.
Can you install new flooring over what is already there?
Sometimes, but it is worth understanding what you give up. Going over an existing floor saves demolition cost, but it raises the finished height at every doorway and transition, it hides whatever condition the old subfloor is in, and it adds another layer between the new floor and something solid. In a rowhome where levelness is already the problem, covering an uneven floor generally produces an uneven new floor. We lift a section and look before advising, and if going over is genuinely fine we will say so — it is the cheaper answer and sometimes the correct one.
My floor feels soft or bouncy. Is that a flooring problem?
Usually not, and that distinction matters. Softness underfoot generally means damaged sheathing or joists deflecting more than they should, and new flooring laid over either will feel exactly the same and may fail faster. If the softness is localised near a bathroom, kitchen or exterior wall, the likely cause is water — a slow leak or a failed seal — and the actual repair is to find the source, fix it, replace the damaged structure and then floor over sound framing. Because we hold the plumbing licence and do framing in-house, that whole sequence is one scope with one estimate.
Which material lasts longest?
Solid hardwood, on the condition that it is somewhere suitable, because it is the only common material that can be refinished repeatedly rather than replaced. A wood floor can be sanded and recoated several times across decades, which is why original floors survive in these houses at all. Tile is extremely durable but unforgiving: it lasts indefinitely over a properly prepared substrate and cracks early over a poor one. Vinyl and laminate are wear layers — once through, they get replaced rather than restored. Longevity is really a question of matching the material to the conditions, not ranking materials in the abstract.
Do you move furniture and appliances?
Tell us what is in the room at the estimate stage and we will include it. Most furniture is straightforward. Appliances need more thought, because a fridge with a water line or a gas range has to be disconnected and reconnected properly rather than dragged clear, and having licensed master plumbers on the crew means that is something we can do rather than a reason to reschedule. What we do want to know in advance is anything unusually heavy or fragile, so the protection and the schedule account for it instead of it becoming a problem on the first morning.

We will check the subfloor, test for moisture where it matters, and give you an itemized estimate that includes the preparation — at no cost.
