Scope of Work
Project Overview
The homeowner reached out to us because their front flagstone walkway had a section that had cracked through and caved in. The broken pieces tilted down into the gap, which left exposed dirt and a hole in the walkway. It was a tripping hazard right in the main path to the front door.
We removed the broken stone pieces, reset the gravel base, and cut new flagstone to fill the gap. We also reset a corner piece that a nearby tree had pushed out of position. The work was contained to the affected area, so the rest of the walkway stayed as it was.
Before / AFTER
Site Conditions
The Property and Site Conditions
The walkway is a flagstone path set in crushed gravel, bordered close on both sides by low plants and garden greenery. One stone near the middle of the run had failed. It cracked all the way through and the pieces had settled down into the base below, leaving an open cavity with dirt and debris showing underneath.
A separate corner piece had also shifted out of place, pushed by a nearby tree. Because the surrounding stones were still solid and level, the repair only needed to address the failed section and reset the corner. The new pieces had to be cut to fit the existing opening so they would sit flush with the stones around them.

What We Did
We removed the broken flagstone and cleared out the loose material, which left a clean angular gap framed by the stones that were staying in place. With the broken pieces out, we could see the base and prep it properly.
We leveled and compacted the base inside the cutout, working with sand and crushed gravel so the new stone would have solid support and not settle again. We used a level across the opening to match the height of the surrounding walkway.
Then we cut and set the new flagstone. The repair used five pieces: two larger stones cut to 17.5 by 26.5 inches and 17.5 by 32.5 inches, and three triangular pieces fit along the edge against the dirt border. We also reset the corner piece the tree had moved, custom-cutting it as needed so it sat back in line with the path. We set each piece, checked that it was flush with the older stones, and confirmed the surface was level end to end.
The finished section sits flush with the rest of the walkway, which took care of the hole and the tripping hazard. The new stone looks a little lighter and cleaner than the weathered stone around it, which is normal for a repair and will even out as it weathers.
