From the very beginning, they were professional, thorough, and incredibly communicative. They came out multiple times to assess the situation and provided a detailed, transparent quote that clearly outlined the scope of work—no hidden fees, no surprises. What really stood out was their honesty and the time they took to explain everything. The level of detail they provided gave us full confidence in their knowledge and capabilities.

They were able to come in and remodel our house after a flood and it far exceeded my expectations. They turned a stressful situation to easy and stress free for us. Special shoutout to Sam, for keeping things honest and straight forward. I knew what I was getting from the get go and if I had any issues he was able to correct them within the hour. Sam is detailed oriented and you can he shows that he cares about the customers by his actions. Chad Whitehouse2025-05-07Trustindex verifies that the original source of the review is Google. Two years after the “shoddy” work they performed we are having to completely replace the flooring. They shot pin nails into laminate flooring but that isn’t the worst part. The patchwork they used to lay a sub floor was crap. They know what they did. They all like to agree and blame the homeowner for whatever goes wrong. One tone even suggesting they because we live in a “trailer house,” the floor would never be perfect. Well now we see clearly what kind of a pieced together project they did, we now have someone who is fixing this fiasco! Don’t use them Danette O'Quin2025-04-22Trustindex verifies that the original source of the review is Google. AS General Contacting is a great company.

We had a major water leak that required us to file a claim through our insurance company, and our plumber referred us to A/S General. From the very beginning, Greg and Sam were incredibly helpful, guiding us through the entire process and helping expedite everything with our insurance company. Greg, Sam, and their entire team were professional, thorough, and communicative every step of the way. The construction crew consistently showed up on time, worked efficiently, and always left the work area clean at the end of each day. Thanks to their attention to detail and quality craftsmanship, our home is now in even better condition than before the water leak. We highly recommend A/S General to anyone in need of home restoration or construction services. Thank you to the entire team for taking such great care of our home!

Why Water Leaks Are a Common Concern in Cardiff By the Sea
Cardiff By the Sea’s unique combination of coastal weather, elevated bluff terrain, and older homes makes it especially vulnerable to water leaks. Ocean air contributes to pipe corrosion, while hillside foundations often develop cracks that let in moisture. Seasonal storms from the Pacific also cause gutter overflows, roof leaks, and hidden interior water damage.
Homes in areas like Cardiff 101 Main Street, San Elijo State Beach, or the local hub at the Cardiff-by-the-Sea Branch Library, tend to have outdated plumbing systems and limited drainage infrastructure, increasing the risk of slab leaks and seepage during heavy rain.


We Proudly Serve These Cardiff By the Sea Areas
We’ve also done water leak inspections and water damage repairs for homes and businesses around other local landmarks in the area like San Elijo State Beach and the San Elijo Lagoon Ecological Reserve & Nature Center.

Water damage from leaks is often eligible for insurance reimbursement. Our team can help document the issue, coordinate with your insurer, and expedite the process.
In coastal homes, high humidity and salt exposure can accelerate pipe corrosion. Many Cardiff homes are also built on older foundations, increasing the risk of slab leaks. Our process includes:

Dangers of Ignoring a Water Leak
In Cardiff By the Sea, even a small hidden water leak can spiral into severe issues. Here’s what to watch out for:
Structural Damage
Water leaks weaken foundational materials over time. On bluffs and hillsides, this can lead to settling, warping of wooden beams, or even retaining wall erosion.
Mold and Mildew Growth
With coastal humidity and lingering moisture, mold spreads quickly behind drywall, under floors, or in crawl spaces, putting your health at risk.
Skyrocketing Water Bills
Leaks often go unnoticed for weeks, especially in second homes or vacation properties. Hundreds of gallons of wasted water can drive your utility bill through the roof.
Electrical Hazards
Moisture and wiring are a dangerous mix. Leaks near your electrical panel, outlets, or appliances increase the risk of fires and short circuits.
Pest Infestations
Wet, dark spaces under decks or behind walls attract rodents and insects. Cardiff’s coastal environment already makes homes prone to termite and ant activity.
Don’t Wait , Fix Leaks Before They Get Worse
If you suspect a leak, act fast. Our team offers same day service and expert leak detection to prevent escalating repairs.
Common Water Leak Problems Cardiff By the Sea Homeowners Face
Cardiff’s proximity to the ocean and elevated terrain creates unique leak related challenges:

Roof Flashing Leaks

Drainage & Gutter Failures
Sudden coastal rain overwhelms aging or improperly sloped systems.
Seepage Through Retaining Walls
Common in properties with ocean view lots.
We’re already helping homeowners in Cardiff By the Sea stay ahead of serious water damage. If you’re seeing signs of moisture, don’t wait and contact us today!

How to Find Hidden Water Leaks in Cardiff By the Sea Homes
Due to the hilly landscape and older architecture, leaks in Cardiff homes often remain hidden. Watch for these warning signs:
Unexplained Moisture on Walls
If your interior paint is bubbling or drywall feels soft, you may have a pipe leak behind the wall, often near kitchens and laundry areas.
Musty Smells in Crawl Spaces or Under Decks
A stale or earthy odor is usually caused by mold forming where you can’t see it. Moisture under raised homes is especially common near the coast.
Sudden Spikes in Water Bills
Notice a jump in your water bill with no change in usage? You may have a slow slab or irrigation leak that needs immediate inspection.
Homes in the Walking District and Rossini Canyon are especially prone to slab and foundation leaks due to soil movement.
