See a Real Fieldstone Foundation We Restored in Somerville
This Somerville home had an 1890s fieldstone foundation with deteriorated mortar, open joints and a weakened corner that needed more than a surface-level repair.
Our team removed the failing mortar, stabilized the vulnerable areas, repointed the stone foundation and completed a two-coat waterproofing system to help protect the basement from future moisture. See the full project, including the condition we found, the repair process and the finished foundation.
Why Foundations Fail in Somerville
Somerville’s housing boom happened long before modern poured-concrete foundation systems became standard. A large portion of the city’s existing housing was built during the late 1800s and early 1900s, which means homeowners throughout neighborhoods such as Winter Hill, Spring Hill, Union Square, Prospect Hill, and East Somerville may be dealing with foundation materials that have already supported the house for well over a century.
Many older foundations were built with fieldstone or rubble stone held together with lime-based mortar. That construction can last for generations, but the mortar does not last forever. Moisture, seasonal temperature changes, basement humidity, settlement, and ordinary aging gradually weaken the joints. Mortar begins turning to sand, gaps form around the stones, and water and cold air find new paths through the wall.
Somerville’s dense development creates another challenge. Homes frequently sit close together on small lots with driveways, walkways, additions, retaining walls, and neighboring properties affecting how water moves around the foundation. When exterior drainage is limited, foundation walls and basement joints can receive more moisture than they were originally built to manage.
The right repair depends on the foundation. An old fieldstone wall with deteriorated lime mortar needs a very different approach from a poured-concrete wall with a vertical crack. We identify the construction first and build the repair around it.
Foundation Crack Repair
Foundation cracks can appear as a house settles, materials age, or moisture and temperature changes put repeated stress on the wall. In Somerville’s older housing stock, it is especially important to determine whether a crack is occurring in poured concrete, block, brick, or an older stone foundation before choosing a repair method.
Our professional foundation crack solutions are designed to stop water intrusion while allowing for the normal movement a foundation experiences over time. We use repair materials and methods appropriate for the type of wall instead of treating every crack with the same product.
Bulkhead Waterproofing
Bulkhead doors and the joints where a bulkhead meets the foundation can become major water-entry points during heavy rain. Aging seals, deteriorated masonry, and poorly drained exterior areas can all allow water to move through these transitions and into the basement.
We provide waterproofing for leaking basement bulkheads using sealing, coatings, masonry repair, and drainage improvements where appropriate. Our goal is to address the actual point of entry rather than simply covering the interior symptoms.
Basement Crack Repair
Cracks in basement walls or floors can become pathways for groundwater, moisture, soil gases, and radon. Even a small opening can become more noticeable during wet weather as water pressure increases around or beneath the foundation.
Our basement wall and floor crack repairs are designed to seal the opening and address the conditions surrounding it. We evaluate the crack first so the repair fits the problem instead of simply filling what is visible.
Garage Floor Crack Repair
Cracks in garage and basement slabs often develop from settlement, shrinkage, moisture below the slab, or years of movement. Left open, they can allow moisture and radon to move through the concrete while the edges of the crack continue to deteriorate.
Our garage floor crack repair service uses specialized materials designed to create a durable barrier against moisture and continued deterioration. Whether you are dealing with a narrow crack or a larger damaged section, we can evaluate the slab and determine the best way to restore it.
Cove Joint Waterproofing
The cove joint is the seam where the basement wall meets the floor. When groundwater builds beneath or around a foundation, this joint can become one of the first places water appears inside the basement.
Our basement cove joint waterproofing system targets this vulnerable transition directly. Depending on the amount of water entering, the solution may include sealing and waterproofing or an interior drainage system connected to a sump pump.
Cold Joint Waterproofing
Somerville homes have been expanded and remodeled for generations. When a new foundation section, addition, stairwell, or other concrete component meets an older section, the connection can create a cold joint that becomes vulnerable to water infiltration.
Our team provides cold joint sealing and waterproofing to close these weak points and keep moisture from moving through the seam.
Basement Waterproofing for Older Somerville Homes
Older foundations can develop several paths for water to enter, including deteriorated mortar, wall and floor cracks, cove joints, pipe penetrations, and drainage issues around the property.
Our waterproofing approach looks at the entire foundation system so we can address the source of the moisture and help keep the basement dry.
Pipe Penetrations and Tie Rods
Any opening through a foundation wall creates a potential path for moisture. Utility pipes, abandoned penetrations, tie rods, and similar openings may begin leaking as the material around them ages or separates from the wall.
Our foundation penetration sealing service closes these gaps with specialized materials designed to maintain a watertight barrier around the opening.
Block and Stone Foundation Repair
Somerville’s late-19th-century and early-20th-century housing includes many foundations built long before modern poured concrete became standard. In fieldstone and rubble walls, the stones may remain serviceable while the lime mortar between them gradually deteriorates and washes away.
Our fieldstone foundation restoration and re-pointing service removes loose, failed mortar and replaces it with new, high-quality mortar. Proper re-pointing helps strengthen the wall, seal open joints, reduce moisture intrusion, limit drafts and pests, and preserve the original foundation.
Frequently Asked Questions
Why do so many older Somerville homes have stone foundations?
Somerville developed rapidly during the late 1800s and early 1900s, when fieldstone, rubble stone, brick, and lime mortar were common foundation materials. Many of those homes are still standing today. A properly maintained stone foundation can last for generations, but the mortar joints eventually need repair as age and moisture cause them to deteriorate.
What does crumbling mortar in a fieldstone basement mean?
Loose or sandy mortar usually means the original joints are deteriorating. The stones themselves may still be in good condition, but missing mortar creates openings that allow moisture, drafts, insects, rodents, and additional movement. Re-pointing removes failed material and replaces it with new mortar to restore the wall.
Can fieldstone foundations be restored?
Yes. Fieldstone foundations can often be restored by removing deteriorated mortar, re-pointing the joints, stabilizing loose or weakened areas, and addressing water intrusion where needed. The right repair depends on the condition of the wall, but many older fieldstone foundations can be strengthened and preserved rather than replaced.
Why does water come through my Somerville basement walls?
Water can enter through deteriorated stone mortar, cracks, pipe penetrations, bulkheads, cove joints, and other weak points in the foundation. Dense development and limited exterior drainage can also make water management more difficult on some Somerville lots. The first step is determining where the water is actually entering so the waterproofing system addresses the source.
Can I seal an old stone foundation with waterproof paint?
Coating over loose or deteriorated mortar does not restore the wall underneath. An older fieldstone foundation should be inspected first, and damaged mortar should be repaired before an appropriate waterproofing system is applied. Using the wrong material can conceal deterioration instead of correcting it.
How long does fieldstone foundation repair take?
The timeline depends on the size and condition of the foundation. Small localized repairs may be completed quickly, while full re-pointing, stabilization, waterproofing, or drainage work requires more time. After inspecting the basement, we can explain the scope of work and expected schedule.
