Plumbing Care for Alamo Heights’ Older Homes
Alamo Heights is one of the oldest suburbs around San Antonio, and many of its houses have plumbing that has been patched, extended and remodeled over several generations. 4M Plumbing Services is a family-owned company based at 5707 Horizon Dr. in San Antonio, led by a Licensed Master Plumber (MPL 39324). We help homeowners in Alamo Heights, Terrell Hills and Olmos Park keep older systems working, and we explain every option before we start. Call (210) 888-8243 or book online.
Three Small Cities, Three Sets of Utilities
Alamo Heights, Terrell Hills and Olmos Park are independent cities surrounded by San Antonio, not neighborhoods of it. Alamo Heights began developing in the 1890s and incorporated in 1922. Terrell Hills saw much of its home building in the 1920s, and H.C. Thorman began developing Olmos Park in the same decade. Both incorporated in 1939. Alamo Heights and Terrell Hills share ZIP 78209, and Olmos Park is in 78212.
- Alamo Heights has its own water. The City of Alamo Heights pumps water from four city wells in the Edwards Aquifer and runs its own water and sewer utility, with sewer lines tying into the SAWS system.
- Terrell Hills is on SAWS. San Antonio Water System provides water and sewer service in Terrell Hills, and SAWS reports typical hardness of 15 to 20 grains per gallon.
- Olmos Park mixes the two. Olmos Park homes are SAWS water customers, while the city keeps its own sewer system and contracts with SAWS to carry and treat the wastewater.
- Older pipe materials. Homes built before the 1960s often have cast-iron drain lines and sometimes galvanized steel water pipes. Both corrode from the inside, causing slow drains, low pressure and rusty water.
- Pier-and-beam homes on clay. Many older houses here sit on pier-and-beam foundations, and the area’s expansive clay soil shrinks and swells between drought and heavy rain, which can stress drain and supply lines.
Plumbing Services for Alamo Heights, Terrell Hills and Olmos Park
Repiping and Pipe Repair for Older Homes
Sputtering, rust-tinted water or a pressure drop when two fixtures run can point to failing galvanized pipe. Our pipe replacement and repair service ranges from replacing one corroded section to a planned whole-house repipe. In pier-and-beam homes, new lines can often run through the crawlspace with less wall damage.
Drain Cleaning and Cast-Iron Sewer Lines
Roots from mature shade trees work their way into older sewer joints. We clear blockages with professional drain cleaning, then use a sewer camera inspection to check for cracked cast iron, root intrusion or sagging pipe. When the line is failing, our sewer line services cover spot repairs and full replacement.
Water Heaters and Tankless Conversions
Older homes often tuck the water heater into a closet, attic or detached garage that was never planned for modern equipment. We repair and replace tank water heaters with proper venting and safety parts, and we can tell you whether a tankless water heater suits your gas supply and space. Ask about current offers on our specials page.
Leak Detection and Slab Leak Repair
Not every home here is pier-and-beam; additions and newer infill homes often sit on slabs. Either way, our leak detection service finds hidden leaks without guesswork, and if the leak is under concrete, we explain slab leak repair options before any cutting.
Water Softeners and Filtration
Edwards Aquifer water is naturally hard. A water softener or filtration system reduces scale on fixtures and inside your water heater. We test before recommending a system, since Alamo Heights city water and SAWS water are not identical.
Gas Line Repair and Upgrades
Some older homes still run original gas piping to ranges, furnaces and water heaters. Our licensed plumbers inspect, repair and extend gas lines and pressure-test every new connection.
24/7 Emergency Plumbing
A burst pipe in a crawlspace or a main line backing up into a tub needs fast help. Our 24-hour emergency plumbing service covers all three cities. Shut off the water at the main valve, then call (210) 888-8243.

Alamo Heights Plumbing FAQs
Do you serve Alamo Heights, Terrell Hills and Olmos Park?
Yes. We serve all three cities, including ZIP codes 78209 and 78212, along with the surrounding San Antonio neighborhoods.
Who provides water in Alamo Heights?
The City of Alamo Heights runs its own water utility using four Edwards Aquifer wells. Terrell Hills is served by SAWS, and Olmos Park homes get SAWS water with a city-run sewer system. Knowing your provider helps us troubleshoot pressure or water quality problems.
My Alamo Heights home has galvanized pipes. Should I repipe?
Galvanized steel corrodes from the inside, which leads to low pressure, rusty water and leaks. If you see those signs, we can inspect the lines and price both targeted repairs and a full repipe so you can decide.
Why do older homes here have so many sewer backups?
Many older homes have cast-iron or clay sewer lines that crack, corrode or let roots in at the joints. A camera inspection shows where the problem is, so you are not paying for repeat drain cleanings.
Do I need a City of San Antonio plumbing permit?
Usually not. Alamo Heights, Terrell Hills and Olmos Park are separate cities, so permitted plumbing work goes through the city where your home is located. We confirm the requirements before starting.
Do you offer emergency plumbing in Alamo Heights?
Yes, at any hour, for burst pipes, sewer backups, major leaks and water heater failures. Turn off your main water valve if water is flowing, then call (210) 888-8243.
