Restoring an Old Crumbling Flagstone Walkway

Flagstone walkways, steps, and patios need occasional maintenance and repair to renew the cracking mortar caused by repeated freezing and thawing. Once the mortar is cracked, moisture can seep in, and if not properly maintained, continued cracking will occur.

If caught in time, repairing hairline cracks is not difficult. Unfortunately ours was neglected for years and needed more than a small repair. We needed a complete overhaul of our walkway, definitely a big job.

After considering various options, we decided to restore the walkway. The process will entail removing all the flagstone and mortar, digging up the concrete, laying new concrete, and setting the flagstone in cement.

Is this the most economical option? Yes and No. We consider this a long term economical solution. By reusing the existing stone and digging up the old concrete, we expect to get another 13 – 15 years use without major issues. The cheaper alternative to just replace the mortar will last only a few years – maybe a good short term solution if you are planning to sell your home? 😉

wvqvgCI%QaWqU7mg2jdhVwA couple new pallets of flagstone were brought in to replace old and broken pieces that can not be reused.

EG4x75TxT4ySEYKGU+ztYwSo happy to have this project done.

vE7Gu4GlT+O%JOf%8pd8NgNext up, all new landscaping! Stay tuned!

We need to allow the mortar to dry for at least a week, then the crew will come back to acid wash and seal the stone. They will also smooth out the sides of the walkway a bit more, giving them a crisper edge.
