Stone and concrete-block foundation repair in northern Vermont
Older stone and concrete-block foundations need repair methods that fit the wall—not a concrete crack product applied everywhere. We repair deteriorated mortar, loose stone, cracked block, leaking joints and unstable wall sections while coordinating drainage and structural work when needed.

Repairs and systems
Work we provide.
Depending on the property, the project may use one of these repairs or combine several into a complete system.
Localized rebuilding
Unstable stone or block sections are carefully dismantled and rebuilt with proper bearing and alignment.
Block crack and joint repair
Cracked units and mortar joints are repaired according to whether the issue is localized leakage or structural movement.
Parging and surface repair
A sound masonry surface can receive a protective parge coat after loose material and water causes are corrected.
Structural reinforcement
Bowing or displaced masonry may need braces, anchors, reinforcing or engineered reconstruction.
Drainage and waterproofing
Exterior water, wall drainage and interior collection are coordinated with masonry repair to keep the wall from staying saturated.

Your estimate
What is included in the plan.
Compatible mortar
Mortar that is much harder than older stone or brick can move damage into the masonry. Existing materials should guide the repair.
Parging is not rebuilding
A surface coat can improve a sound wall but should not be used to conceal loose stone or movement.
Water behind the wall
Sealing the interior face without controlling water can move the leak or accelerate deterioration.
Openings and loads
Bulkheads, windows, beams and concentrated loads often need extra attention during masonry repair.

Common questions
Stone & Block Foundation Repair FAQs
These answers cover the questions homeowners ask most often. Your inspection and written estimate will address the conditions at your home.
Should an old stone foundation be covered with cement?
Not automatically. A parge coat can protect a stable wall, but it should not hide failed mortar, loose stone or water pressure. The mortar and coating must also be compatible with the existing masonry.
Can water be stopped in a stone foundation?
Water can usually be reduced or controlled through repointing, exterior drainage, wall drainage, interior collection and humidity control. Because stone walls contain many joints, the solution is often a system rather than one injected crack.
When does a stone wall need rebuilding?
Sections with significant bulging, loose material, lost bearing or deep deterioration may need rebuilding. An on-site evaluation determines whether selective repair is enough.
