Front porch pavers go down in one of two ways: thin pavers (about 1 to 1 1/4 inches) bonded to a sound concrete porch, or full-thickness pavers on a compacted gravel base when you are building the porch or stoop from scratch. Which one you can use is decided by a single measurement, the gap between the porch surface and the door threshold, because every inch of pavers comes straight out of it. A porch is the only patio that has to negotiate with a door, and the door never moves.
Measure the door gap before you pick front porch pavers
Write down three numbers:
- Porch surface to the top of the threshold. This is your height budget.
- Porch surface to the bottom of any storm or screen door at its lowest point in the swing. Storm doors swing out, low, over exactly the spot you are raising. (They are the usual casualty, discovered the first evening someone tries to take the dog out.)
- Every step riser, top to bottom.
Compare them with what pavers add. A standard 2 3/8-inch paver on a 1-inch sand bed adds about 3 3/8 inches. A 1 1/4-inch thin paver on a 1/2-inch mortar bed adds about 1 3/4 inches.
I read IRC section R311.3.1 on UpCodes to see how much room the code leaves. Where a door swings over the landing, the landing may sit no more than 1 1/2 inches below the threshold; otherwise the limit is 7 3/4 inches. That is a maximum drop. The minimum is set by water: the pavers must stay clearly below the threshold and pitch away from it, or rain runs under the door. Check with your local building department, since adoption varies. We have a separate page on front entry landing size if you need the specifics. The paver height below door threshold guide covers this in more depth.
Which porch have you got?
| What is there now | Best paver route | Watch for |
|---|---|---|
| Sound concrete slab, little height to spare | Thin pavers set in mortar or on adhesive | Door clearance, the top riser |
| Sound slab with 3 1/2 in or more below the threshold | Full pavers on sand over the slab, or thin pavers | Drainage through the sand layer |
| Cracked, heaving or sunken slab | Break it out and build on gravel | A bad slab telegraphs through a bonded overlay |
| No porch, just a landing at grade | Full pavers on a compacted base | Grade against the foundation |
| Wood porch deck | Leave pavers off it | Framing is not built for masonry weight |
Most concrete porches land in the first row, which is why I'd pick thin pavers on nearly any existing porch. A full paver needs over 3 inches of headroom that most doors simply don't have. Our guide to thin pavers covers the product types.
Bonding thin pavers to an existing porch
I went through Remington Avenue's front porch thin brick tutorial photo by photo. Its best advice: dry-lay the whole pattern before anything gets glued, and save offcuts for the fiddly corners.
- Check the slab. Hairline shrinkage cracks are fine. A crack with one side higher than the other, or a slab that rocks, means the porch is moving, and anything bonded to it will crack along the same line.
- Clean it to bare concrete. Paint, sealer and moss stop anything gripping.
- Dry-lay the pattern from the door outward, so the full pieces sit where people look and the cuts land at the step edge.
- Set a border first. Glue the edge course along the porch edge with construction adhesive or mortar, then fill the field inside it.
- Keep the slope. Hold the bed at an even thickness so the pavers follow the porch's existing fall. Never pack it up at the house wall to "level" it.
- Grout the joints once the bed sets, keeping the grout just below the faces.
Mortar bed versus sand over a slab is covered in pavers over concrete.
Building a new paver porch on gravel
With no slab, a front porch is a small patio with an audience. Dig out, compact the soil, lay at least 4 inches of compacted crushed stone (more on wet or frost-prone ground), screed 1 inch of loose concrete sand, lay, restrain the edges and compact. The difference is that the foundation forms one side: slope away from it, and keep the surface at least 2 inches below any wood siding (IRC R317.1).
A stoop higher than one step needs a wall-block edge, backfilled and compacted in thin layers. That is a small raised patio, not an overlay.
The steps come with the porch
Raise the porch and the top riser grows by the same amount, because the tread below stays put. The IRC caps a riser at 7 3/4 inches with only 3/8 inch of variation in a flight. A porch with 7-inch risers that gains 1 3/4 inches of pavers now has one 8 3/4-inch riser, which fails on both counts. It is also the step people trip on, because their legs have learned the others.
The fix is to overlay every tread by the same amount, so all the risers move together. Our guide to overlaying concrete steps with pavers walks through bullnose treads and riser faces.
A paver that behaves at the front door
Unilock's front entrance design advice names lighting and slip-resistant surfaces as the safety priorities, and prefers calcium- or sodium-based de-icers over magnesium-based ones.
- Texture over polish. A tumbled or textured face grips better when wet than a smooth, sealed one.
- Skip the high-gloss sealer on the porch, where a wet shoe meets it first.
- Match the house, not the catalog. Borrow a color from the brick, trim or roof.
Let the door set the thickness
Front porch pavers come down to this: the door gap sets the paver, and the steps rise with the porch. On most concrete porches that means thin pavers bonded down and every tread overlaid to match. Measure under the storm door before you buy a single pallet. The door will not be negotiating.
FAQ
Can you put pavers over a concrete front porch?
Yes, if the slab is sound and there is height below the threshold. Thin pavers in mortar add about 1 3/4 inches; full pavers on sand add about 3 3/8.
How thick should pavers be on a front porch?
Over an existing slab, use thin pavers of about 1 to 1 1/4 inches unless you have more than 3 1/2 inches under the threshold. On a new porch built on gravel, standard 2 3/8-inch pavers are the norm.
What do you do about the step when you raise a porch?
Raise the treads by the same amount so every riser stays equal. The IRC allows no more than 3/8 inch of variation between risers in a flight, and caps each one at 7 3/4 inches.
Can you put pavers on a wooden porch?
It isn't a good idea. Porch framing isn't designed for masonry weight, and trapped moisture rots joists. Use deck tiles made for wood framing, or rebuild the porch as a stoop.
