Why Waterproofing is Crucial for Glendale Homes
Glendale and its surrounding areas, while enjoying plenty of sunshine, are certainly no strangers to rainfall. Even moderate amounts of precipitation over time can take a significant toll on our homes if they aren’t properly protected.
The freeze-thaw cycles we sometimes experience in the cooler months can exacerbate issues, causing materials to expand and contract, leading to cracks and vulnerabilities where water can penetrate.
Ignoring waterproofing needs can lead to a variety of problems that affect both the structural integrity and the comfort of your home:
- Foundation Damage: Water pooling around your foundation can exert pressure, leading to cracks and leaks. This can compromise the stability of your entire home and result in costly repairs.
- Basement and Crawl Space Flooding: Low-lying areas like basements and crawl spaces are particularly susceptible to flooding and moisture buildup, creating ideal conditions for mold and mildew growth.
- Roof Leaks: Damaged or aging roofs are a primary entry point for rainwater, which can damage ceilings, walls, and insulation. Undetected leaks can cause significant structural rot over time.
- Siding and Exterior Damage: Water can seep behind siding, causing it to rot, warp, or detach. This not only looks unsightly but also leaves your home vulnerable to further water intrusion.
- Interior Damage: Leaks and moisture can damage drywall, plaster, paint, and flooring, leading to stains, discoloration, and the need for interior repairs.
- Mold and Mildew Growth: Excess moisture creates a breeding ground for mold and mildew, which can trigger allergies, respiratory problems, and negatively impact indoor air quality.
- Decreased Energy Efficiency: Wet insulation loses its effectiveness, leading to higher heating and cooling costs.
Investing in proper waterproofing measures is a proactive way to prevent these issues, protect your home’s value, and ensure a healthy and comfortable living environment for you and your family right here in the Glendale community.

Essential Waterproofing Tips for Glendale Homeowners
Now, let’s get down to the practical steps you can take to waterproof your Glendale home and safeguard it against the rain. Whether you’re a new homeowner or have lived here for years, these tips will help you assess your home’s vulnerabilities and take proactive measures.

1. Inspect and Maintain Your Roof
Your roof is your home’s primary defense against the rain. Regular inspections and timely maintenance are crucial.
- Check for Damaged or Missing Shingles: Look for cracked, curled, or missing shingles. Replace them promptly to prevent leaks.
- Inspect Flashings: Examine the flashing around chimneys, vents, and other roof penetrations. Ensure it’s secure and in good condition. Damaged flashing is a common source of leaks.
- Clean Gutters and Downspouts: Clogged gutters can cause water to back up and overflow, potentially damaging your roof, fascia, and foundation. Clean them at least twice a year, and more frequently if you have many trees around your property. Ensure downspouts direct water away from your foundation.
- Trim Overhanging Trees: Tree branches that hang over your roof can damage shingles and contribute to debris buildup in gutters. Trim them back to create a safe distance.
2. Address Foundation Issues
A solid, waterproofed foundation is essential for the long-term health of your home.
- Inspect for Cracks: Regularly check your foundation walls (both interior and exterior if accessible) for cracks. Even small cracks can allow water to seep in. Seal any cracks with a concrete crack sealant.
- Ensure Proper Grading: The ground around your foundation should slope away from your house. This helps direct rainwater away from the foundation. If you notice water pooling near your foundation, consider regrading.
- Consider a French Drain: If you consistently experience water issues around your foundation or in your basement, a French drain system can help collect and redirect groundwater away from your home.
- Seal Foundation Walls: For added protection, consider applying a waterproof sealant to the exterior of your foundation walls (if accessible) or installing a waterproofing membrane.
3. Seal Windows and Doors
Windows and doors are common points of water infiltration.
- Check Weather Stripping and Caulking: Inspect the weather stripping around your doors and windows for damage or wear. Replace it as needed. Ensure all gaps and seams around the frames are properly sealed with high-quality, waterproof caulk.
- Ensure Proper Drainage: Make sure weep holes in window and door frames are clear and allowing water to drain properly.
- Consider Storm Windows and Doors: In areas prone to heavy rainfall, storm windows and doors can provide an extra layer of protection against water and wind.
4. Improve Drainage Around Your Property
Effective drainage is key to preventing water from accumulating around your home.
- Extend Downspouts: Ensure your downspouts extend at least 4-6 feet away from your foundation to direct water away from your home’s base. Consider using downspout extensions.
- Install Surface Drains: In areas where water tends to pool, consider installing surface drains to collect and redirect the water.
- Create Swales: Swales are shallow channels designed to intercept and redirect surface runoff. They can be a natural and effective way to manage water flow on your property.
5. Pay Attention to Your Landscape
Your landscaping can play a role in managing rainwater.
- Avoid Overwatering: Excessive watering can saturate the soil around your foundation. Water your lawn and garden responsibly.
- Choose Native Plants: Native plants are often better adapted to local rainfall patterns and can help improve soil drainage.
- Use Mulch Strategically: While mulch can help retain moisture in garden beds, avoid piling it up directly against your foundation, as this can trap moisture.
6. Interior Waterproofing Measures
Even with good exterior waterproofing, moisture can sometimes find its way inside.
- Use Moisture-Resistant Materials: When remodeling bathrooms, kitchens, or basements, choose moisture-resistant materials like tile, vinyl, and moisture-resistant drywall.
- Ensure Proper Ventilation: Good ventilation in bathrooms and kitchens helps to remove excess humidity, reducing the risk of condensation and mold growth. Use exhaust fans regularly.
- Consider a Dehumidifier: In damp basements or crawl spaces, a dehumidifier can help to remove excess moisture from the air.
- Address Plumbing Leaks Promptly: Even small leaks can introduce significant amounts of moisture into your home. Repair any leaks immediately.

Local Considerations for Glendale & Surrounding Areas
Glendale’s terrain, with its mix of flatlands and hillside properties, presents unique waterproofing challenges. Homes on slopes may be more susceptible to runoff issues, requiring careful grading and drainage solutions.
Older homes in Glendale might have foundations or roofing systems that are nearing the end of their lifespan and require more diligent inspection and maintenance.
Furthermore, local building codes in Glendale may have specific requirements regarding drainage and stormwater management, especially for new construction and significant renovations. It’s always wise to check with the City of Glendale’s Building and Safety Division to ensure your waterproofing efforts align with local regulations.

It’s a good idea to inspect your roof at least twice a year (spring and fall) and after any significant storms. Early detection of issues can prevent costly repairs.
What are the benefits of installing a French drain?
A French drain can effectively redirect groundwater away from your foundation, preventing basement flooding and reducing hydrostatic pressure on foundation walls.
Is it necessary to seal cracks in my concrete foundation?
Yes, even small cracks can allow water to seep into your foundation, potentially leading to larger problems over time. Sealing them is a relatively simple and cost-effective preventative measure.
What type of caulk should I use for waterproofing around windows and doors?
