When you think about protecting your home, your basement probably isn’t the first thing that comes to mind—but it should be. Basement waterproofing is one of the most important investments you can make to keep your home safe from water damage, mold, and structural deterioration. For homeowners in San Jose, where moisture and shifting soil can cause recurring foundation issues, proper waterproofing ensures lasting protection and peace of mind.
Why Basement Waterproofing Matters
Your basement forms the foundation of your home. If it becomes compromised by water, everything above it is at risk. Moisture seeps into cracks, weakens concrete, and leads to mold growth. Over time, that can result in serious problems such as bowing walls, rotting wood, and even a sinking foundation.
Basement waterproofing involves sealing every potential entry point for water—from wall cracks to floor joints and window wells. When done professionally, it creates a durable barrier that keeps water out, controls humidity, and protects your home’s structure for decades.
Common Signs You Need Basement Waterproofing
Water damage often starts small, but the signs are easy to spot if you know what to look for. If you notice any of the following, it’s time to act quickly:
- Damp or musty smells that never go away
- Water stains on basement walls or floors
- Cracks or peeling paint on concrete surfaces
- White, powdery residue (efflorescence) appearing on walls
- Mold growth in corners or around baseboards
- Warping or discoloration on wooden framing
Ignoring these symptoms can lead to major repairs later. Professional basement waterproofing prevents minor leaks from becoming expensive structural issues.
The Professional Waterproofing Process
At Armor Coatings Inc, we approach every project with precision and care. With over 39 years of experience in San Jose, we’ve developed a proven process that ensures each basement stays dry, protected, and structurally sound.
- Comprehensive Inspection
We begin with a detailed assessment of your basement to identify water entry points, structural cracks, and areas of concern. - Surface Preparation
Before applying waterproof coatings, we clean and prepare all surfaces to ensure the sealants adhere properly and last longer. - Crack Repair and Joint Sealing
Using high-quality epoxy or polyurethane injections, we repair cracks and fill joints to stop leaks before they spread. - Application of Waterproofing System
Depending on your needs, we use either interior sealants, exterior coatings, or a combination of both. This layered defense ensures that no water or vapor penetrates the foundation. - Final Moisture Testing and Inspection
Once complete, we test for moisture levels and vapor pressure to guarantee your basement’s full protection.
This process not only waterproofs your basement—it also strengthens your foundation and enhances your home’s energy efficiency.
The Benefits of Basement Waterproofing
Waterproofing your basement delivers both immediate and long-term benefits:
- Prevents Mold and Mildew: Stops the growth of harmful spores that can trigger allergies and respiratory problems.
- Protects Structural Integrity: Keeps your foundation strong and prevents cracks from spreading.
- Improves Indoor Air Quality: Reduces humidity, creating a healthier home environment.
- Increases Property Value: A dry, well-maintained basement is a major selling point.
- Energy Efficiency: Helps maintain consistent indoor temperatures by keeping the basement dry and insulated.
When done by professionals, basement waterproofing becomes more than maintenance—it’s a long-term investment in your home’s safety and value.

Basement Waterproofing vs. Basement Sealing
While the terms are often used interchangeably, basement waterproofing and basement sealing are slightly different. Sealing is primarily a preventive measure designed to block surface moisture. Waterproofing, on the other hand, is a complete moisture control system that addresses both internal and external water intrusion.
For homes in San Jose, waterproofing is the more comprehensive choice. It tackles both hydrostatic pressure (water pushing through the walls) and condensation issues inside the basement, giving your foundation full protection.
Maintenance Tips After Waterproofing
To make the most of your investment, here are some simple maintenance steps:
- Keep your gutters clean and ensure downspouts drain away from your home.
- Inspect your basement regularly for any signs of moisture or new cracks.
- Avoid stacking materials directly against basement walls to maintain airflow.
- Schedule professional inspections every few years to ensure long-term performance.
These small habits go a long way in maintaining a dry, safe, and structurally sound basement.
