Downtown Sanford’s older buildings were not all built the same way, fieldstone, brick, and poured concrete foundations all show up within a few blocks of each other depending on when a given building went up. That mix means a “crack” means something different from one house to the next, and we do not treat them the same way.
| Foundation type | What actually shows up as damage | How we fix it |
|---|---|---|
| Poured concrete | A vertical or diagonal crack through the solid wall | Polyurethane or epoxy injection along the full depth |
| Fieldstone or brick | An opened mortar joint between stones or bricks, not a crack through solid material | Repointing and injection at the joint itself |
What repair costs
Standard poured-wall injection carries a 10-year warranty against leakage through the treated area. Where the crack is tied to a wall that is actually moving, structural epoxy injection carries a 10-year warranty on the bond, and is one piece of a larger fix. Mortar joint repair on a stone or brick foundation is priced separately, since it is a different scope of work entirely. We price after we have seen the actual wall.
The one thing that matters more than what the crack looks like
Photos do not tell us whether a crack is old and settled or actively getting worse, and homeowners often cannot tell either just by looking. What we actually check on site: whether it has ever let water through, whether either side has shifted relative to the other, and whether anything else in the house has changed at the same time, a door that started sticking, a floor that developed a slope. Absent all three, we are almost always looking at something old and stable.
Sanford’s older foundations, fieldstone included
Census data puts Sanford’s median home at built-in-1973, and the town’s older mill-era housing runs back well before that, some of it on fieldstone or block foundations rather than poured concrete. Fieldstone does not crack the way a poured wall does, since it is not one continuous pour, so the failure signs are different: mortar joints crumbling or washing out, stones that have shifted out of line, rather than a single crack running through the wall. A poured wall from any era cracks the way poured concrete always has. What 603 is checking for changes with which one you have, which is part of what the first walk-through is for.
Frequently asked questions
My foundation is fieldstone. Does that make repairs more complicated?
Different, not necessarily more complicated. Stone and brick foundations need repointing rather than the injection line we would use on a poured wall, and we price that separately once we know which one your house has.
How do I know if my crack needs attention now or can wait?
If it is dry and has not changed, it can wait. If it is wet, growing, or paired with another sign of movement in the house, do not wait on it.
Do you need to dig outside to fix this?
Not for standard interior injection work. That is done from inside the basement.
Will the repair be visible afterward?
Yes, unless the wall gets a finish over it later. The leak stops regardless.
What a recent customer said
Very knowledgeable and professional to work with. Had a top to bottom ceiling wall crack filled on the 22nd and with heavy rain experienced on the 23rd there was not the slightest drop of water on the basement floor. Job well done!
