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.

Olivia Bue2025-03-21Trustindex verifies that the original source of the review is Google. 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 Downtown San Diego
Downtown San Diego’s dense urban layout, aging infrastructure, and mix of high-rise buildings and historic homes make it especially vulnerable to water leaks. Many buildings use stacked plumbing systems, shared walls, and older copper pipes that are prone to corrosion and slab leaks.
Frequent sunshine is interrupted by sudden seasonal rains, which can expose weaknesses in rooftop systems and windows. With expensive finishes, multi-unit dwellings, and the risk of leaks spreading across walls or floors, early detection is essential for minimizing damage.
Neighborhoods like Little Italy and Gaslamp Quarter combine modern developments with century old structures each with unique leak risks.

We’ve also done water leak inspections and water damage repairs for homes and businesses around trending local landmarks in the area like The Rady Shell at Jacobs Park and Seaport Village.

Dangers of Ignoring a Water Leak
In Downtown San Diego, even a small, hidden water leak can lead to major problems if left untreated. Here are some of the most serious risks of ignoring a leak in your home or building:
Structural Damage
Leaks in multi level buildings can compromise ceilings, load-bearing walls, and flooring systems. Left unchecked, these issues often require costly reconstruction.
Mold and Mildew Growth
High humidity in enclosed urban units especially those with poor ventilation creates perfect conditions for mold. It can spread through drywall, HVAC systems, and shared ducts.
Skyrocketing Water Bills
Leaks in shared meter systems or within units can result in massive overages that get passed on to owners or tenants.
Electrical Hazards
Water traveling into shared walls or ceilings can reach outlets, light fixtures, or appliance panels, increasing the risk of fire or system failure.
Pest Infestations
Moisture in urban buildings attracts roaches, silverfish, and rodents especially near basements and trash rooms.

Most Common Water Leaks We See in Downtown San Diego

How to Find Hidden Water Leaks in Downtown San Diego Homes
High-rise condos, townhomes, and mixed-use buildings in Downtown San Diego all hide leaks in different ways. Here’s what to look for:
Unexplained Moisture on Walls
Dark spots or bubbling drywall, especially in corners or near shared walls can indicate an interior leak or neighbor’s pipe failure.
Musty Smells in Crawl Spaces or Utility Rooms
Condos with limited ventilation may trap moisture after HVAC or water heater malfunctions.
Sudden Spikes in Water Bills
If you’re getting high bills without a change in usage, there could be a leak in your slab, walls, or appliance lines.
Homes and buildings in East Village and Columbia District often face slab or shared wall leaks due to their age and construction density.
