"The crew came out to look at our foundation within two days of calling. They explained exactly what was causing the cracks near our doorframes - the clay soil had been shifting for years. Work was done on schedule and the doors close properly now for the first time in a long time."
Robert M., Claremont - Foundation repair
"Our chimney had been leaking every winter and we kept patching it ourselves. They found the cracked liner and deteriorated crown in one visit, gave us a written estimate the same day, and had it fixed before the rainy season. No more water in the firebox."
Sandra K., Upland - Chimney repair
"The brick on our 1940s home near the Village was badly deteriorated and a previous contractor had used the wrong mortar years ago. These guys matched the original lime mortar, ground everything out properly, and the wall looks like it was never touched. Color match is excellent."
David T., Pomona - Tuckpointing

Claremont summers regularly top 95 degrees with very low humidity - conditions that dry mortar out and cause it to crack faster than in coastal cities. The Inland Empire heat cycle means tuckpointing intervals are shorter here than in most of California. The Brick Industry Association recommends inspecting mortar joints every five to ten years in hot, dry climates.
Clay-heavy soils at the base of the San Gabriel Mountains swell when wet and shrink when dry. That repeated movement pushes and pulls on your foundation every season. The California Department of Conservation maps expansive soil hazards across the state - and Claremont sits squarely in a high-risk zone.
Both perform well in dry heat, but pavers handle the thermal expansion-contraction cycle better because individual units can shift slightly without cracking the whole surface. Poured concrete surfaces in the Inland Empire can develop shrinkage cracks within a few years of installation if the mix and curing process are not managed carefully.
Water pooling within a foot or two of your foundation after rain is a warning sign. Claremont gets most of its annual rainfall between November and March, and clay soils saturate quickly. Repeated wet-dry cycles erode mortar joints and accelerate foundation cracking. Good drainage around the perimeter is the first line of defense.
Yes. Homes built before the 1950s typically used soft lime-based mortar, not the harder cement mortars used today. Using modern high-strength mortar on an older wall forces the brick to absorb stress it was not designed for - and the brick cracks, not the mortar. Matching the original mortar composition is one of the most important skills in historic masonry repair.
Claremont sits near both the San Andreas and Cucamonga fault systems. Even minor tremors can loosen mortar joints and shift unreinforced masonry over time. California requires permits for structural masonry repairs partly to ensure seismic standards are met. The California Geological Survey publishes updated fault maps for homeowners who want to understand their specific exposure.

If mortar crumbles when you press it or you can see dark recessed gaps, water is already getting in. That makes tuckpointing urgent. If joints look slightly weathered but are still firm, you have time - but scheduling within the season is smart before the next rainy period.
Small hairline cracks in poured concrete are often cosmetic. But diagonal or stair-step cracks that grow wider over time, or cracks accompanied by sticking doors, indicate movement. Left unaddressed, the repair cost typically increases as more structural support becomes necessary.
Yes. A chimney can look structurally sound from the outside while the liner inside is cracked or deteriorated. The National Fire Protection Association recommends annual inspections. A camera inspection of the flue is the only reliable way to know what is actually wrong before any repair is quoted.

Claremont is a city of about 36,000 residents at the eastern edge of Los Angeles County, nestled up against the base of the San Gabriel Mountains. The city is home to the Claremont Colleges, a group of seven nationally recognized institutions that anchor the center of town, and its walkable downtown - known as The Village - draws residents and visitors throughout the year.
A large share of Claremont's residential neighborhoods, particularly near The Village and the tree-lined streets surrounding the Colleges, feature Craftsman bungalows and Spanish Colonial Revival homes built between the 1920s and 1960s. These properties are well-maintained and reflect real homeowner investment - but they also carry the masonry challenges that come with age: soft original mortar, aging brick, and foundations that were built before modern seismic standards existed. Homeowners who enjoy outdoor access also have the Thompson Creek Trail running along the foothills - an area where newer construction meets older neighborhoods.
Claremont Concrete & Masonry has worked throughout Claremont since 2016, on everything from tuckpointing original brick near the Colleges to foundation stabilization in the foothills north of the city. We know the local housing stock, the city permit process at Claremont Building and Safety, and the soil conditions that make masonry repair here different from newer cities farther east.
