Stone That Holds the House Together
Stone foundation repointing and repair in Scranton for homes where worn mortar joints are exposing rubble or fieldstone to further deterioration
Scranton's older residential neighborhoods were built on rubble and fieldstone foundations, a construction method standard through the early twentieth century that left mortar joints exposed to decades of loading, moisture intrusion, and settlement. Litvin & Sons works on these foundations in Scranton, performing the kind of thorough repointing that stabilizes the wall rather than masking its condition. Jim Litvin, Pennsylvania contractor license No. 4498, has spent 30 years on exactly the type of older home stock common across this part of the region—where foundation work demands an eye for what the stone is actually doing before new mortar goes in.
The repointing process begins by raking out loose and deteriorated mortar back to sound material—not simply applying new mix over old. Once the joints are cleaned to a solid base, new mortar is packed in and finished to match the existing profile so the wall reads as original. Stones that have cracked or shifted are assessed as part of the same scope, and any displacement is addressed before the wall is closed. In Hyde Park and comparable areas where homes date to the early 1900s, the mortar mix and joint width vary considerably from house to house, which makes profile matching a real technical decision rather than an afterthought.
Arrange an on-site evaluation with Litvin & Sons to assess the current condition of your stone foundation and identify which joints and stones require immediate attention.
What Proper Stone Foundation Repointing Requires
Common Questions About This Service
Stone foundation work on older homes raises specific questions about process, materials, and scope. The answers below address how the work is actually performed and what property owners should expect when repointing is part of the job.
How do you know if a stone foundation needs repointing rather than a
full rebuild? When mortar joints are recessed, crumbling, or pulling away from the face of the stone, repointing is typically the appropriate response—as long as the stones themselves are stable and the wall has not shifted significantly out of plane. A displaced or bowing section requires structural assessment before repointing can resolve the condition.
What does raking out mortar to sound material actually mean, and why does it matter?
Raking removes deteriorated mortar until the tool meets material that is still bonded and intact, typically a minimum depth of three-quarters of an inch. Packing new mortar over a soft or powdering base creates a bond failure that returns within a few years, which is how shortcuts in repointing become visible again quickly.

How is the mortar profile matched to the original wall?
The existing joint profile—whether it was struck flat, slightly concave, or raked to a set depth—is observed before work begins and the finishing tool is selected to replicate it. On Scranton-area fieldstone foundations, joint widths vary because rubble construction was not uniform, so the profile work is done section by section rather than with a single pass.
What happens to stones that are cracked or displaced during a repointing project?
Cracked or displaced stones are assessed as part of the scope rather than repointed around. Depending on the severity, a stone may be reset, replaced with a matching piece, or stabilized in place before the joint work proceeds—leaving a displaced stone in position and pointing around it does not restore the wall's load path.
When should stone foundation repointing be completed before other work begins?
Repointing should be finished before a basement is finished or an addition is framed, because both involve adding load or attaching structure to the existing foundation. Starting finish work on a wall with deteriorated joints means the new construction may need to be disturbed later to address what was already visible.
