Plumbing, HVAC and Electrical Service in Elgin

Elgin grew up around the railroad and the brick kilns, and it still looks the part: a downtown of brick streets and brick storefronts, the old depot, and the sausage that gave the town its state-designated nickname. The houses nearest downtown date from the early 1900s, with Victorian trim, pier-and-beam floors and plumbing that has been patched by every owner since. Newer neighborhoods surround them, from 1970s and 1980s ranch homes to the subdivisions going up along US 290 and State Highway 95 as Austin’s growth pushes east.

Radiant has served Elgin since 1999, and the ground is what ties the calls together. All of Elgin sits on Blackland Prairie clay, deep and expansive, and it moves every house on it a little each year. Older homes settle; slab homes crack and shift; sewer lines separate at the joints. The most common Elgin calls are a leak that showed up as a wet spot or a high bill, a drain that backs up after every heavy rain, an air conditioner that finally quit in July, and, in the historic homes, wiring and pipe that were never meant to carry a modern household.

Elgin is inside our Austin service area, so our licensed electricians work here alongside our plumbers and HVAC technicians. Every visit starts with a background-checked technician diagnosing the actual problem, explaining it in plain language and giving you a price to approve before any work begins. The Home Comfort Guarantee covers what we do.

  • Century-old homes Crawlspace plumbing, cast iron drains, old panels and retrofit ductwork are familiar ground for our technicians.
  • Clay-soil plumbing We locate slab leaks and shifted sewer joints with cameras and sensors before recommending any digging.
  • Three licensed trades Plumbing, HVAC and electrical from one company, with the same upfront price and guarantee on each.

Local Knowledge

How Elgin Ground and Weather Treat a House

Blackland clay. Elgin sits on some of the deepest expansive clay in Central Texas. It swells in a wet spring, shrinks and cracks in August, and every foundation moves with it. Pier-and-beam homes near downtown settle unevenly; slab homes in the newer subdivisions lift and drop at the edges. The pipe in and under those foundations takes the strain, which is why slab leaks and separated sewer joints are the signature Elgin plumbing problem. Watering the soil evenly around the foundation in a drought does more good than most people expect.

Three generations of plumbing. The historic homes carry galvanized supply and cast iron drains, often with copper or PEX spliced in over the decades. The 1970s and 1980s neighborhoods have copper in the slab and cast iron or early PVC underneath. The new subdivisions have PEX and PVC. Each fails differently, and knowing the era of your house tells us where to look first. A repipe is on the table only when patching has stopped making sense.

Wells and propane outside town. Beyond the city limits, homes run on wells or rural water supply lines, septic systems and propane. We service the house side of a well, drains up to the septic tank, and propane furnaces and water heaters along with their gas piping.

Hard water. Elgin water is hard enough to scale water heaters and leave white crust on fixtures. A softener and an annual heater flush are the two upgrades that pay for themselves.

Open-prairie weather. Summer heat and spring storms hit harder with nothing to block them, and power flickers are common on the long lines east of town. Winter freezes reach exposed crawlspace pipe and hose bibs; February 2021 broke plenty of both across Bastrop County.

Frequently Asked Questions

Our pier-and-beam house near downtown Elgin has a sag in the floor and a toilet that rocks. Is that plumbing or foundation?

Sometimes both, and the order matters. A leaking drain under a pier-and-beam house drips onto the soil below, and wet clay under one pier lets it sink while the rest of the house stays put. That is your sag. The rocking toilet is usually a flange that has broken free of a subfloor softened by the same leak. We start in the crawlspace: camera the drains, pressure-test the supply and look for wet ground. If a leak is feeding the problem, fixing it comes first, or the foundation repair will not hold. If the crawlspace is dry, the movement is the clay itself and you need a foundation contractor, and we will tell you that rather than sell you a plumbing repair you do not need.

Our subdivision is only a few years old and the sewer line has already backed up twice. Why would a new line fail?

Two usual reasons in Elgin. The first is the clay: a new PVC sewer line laid in a trench of expansive soil can settle into a low spot, or belly, within a few seasons, and that belly holds water and catches solids until it clogs. The second is what went down the line during and after construction: drywall mud, grout, wipes and grease. Cabling clears the stoppage, but a camera inspection shows which it is: a belly, a separated joint or just a bad habit in the house. If the line itself is the problem, a spot repair on the low section is far cheaper than living with an annual backup. Our drain work comes with a no-backup promise.

Does Radiant come out to Elgin from Austin, and does it cost more because of the distance?

Yes, we come, and no, the distance does not change the price. Elgin is part of our regular Austin-area service territory, not a special trip, and the price you approve before work starts is the same price you would pay in central Austin. That holds on nights, weekends and holidays too, because we do not add surprise fees for any of them. If you would rather skip dispatch fees entirely, Care Club includes two HVAC tune-ups a year, a whole-home plumbing safety inspection, priority scheduling and 5% off repairs for Elgin homes just like everywhere else we serve.

The AC in our 1980s Elgin house runs constantly but the house stays dusty and humid. Is that a duct problem?

Very often, yes. In a 1980s home the ductwork runs through an attic or a crawlspace, and after forty years the joints have loosened, the tape has failed and the insulation has slumped. A leaky return pulls hot, dusty, humid air from the attic straight into the system; leaky supply ducts push your cooled air out before it reaches the rooms. The system runs longer, the house never quite dries out and the filter loads up fast. We test the ducts, seal what can be sealed and replace runs that are past saving, then check whether the system was undersized to begin with. If humidity is still a problem after that, a whole-home dehumidifier is the next step, not a bigger AC.

Our 18 year old HVAC system finally gave out this past week, so we reached out to Radiant to see what could be done. They sent a tech out named Bryan the same day, and he did a great job looking over the entire HVAC system. He was friendly and helpful in explaining everything that he saw, and our options moving forward. We decided to replace the entire system, so we met with Jacob (same day thankfully) to find the best HVAC system for our needs. Jacob was friendly, professional, and did a great job explaining the different options on offer. Radiant was able to set-up next day install, which was much appreciated, because the temps were still going to be cold in the coming days.

The install team consisted of Carlos and Pablo, who were very courteous and professional, and were kind enough to answer any questions I had regarding the install. They did a great job installing our new HVAC system, and were tidy which is always appreciated! Before they left, they explained everything that had been done, and showed me photos of the work.

Our entire experience from start to finish was great. I appreciate that they send photos of who is coming to your home too. Friendly, kind, professional team members, and good work all the way around. Thanks Radiant!

I had Radiant Plumbing replace my tankless water heater, damaged in the Feb. 2021 snowmageddon storm with a new unit. The process was smooth and professional from start to finish. The plumber, James, was extremely knowledgeable and thoroughly explained my options to me. The cost and time to perform the installation were just as estimated. When he was done, James explained how to maintain the system, what service would be needed and how to perform it, and answered all of my engineering geek questions. It was a thoroughly positive experience. I have used several different plumbers in Austin over the past 15 yrs, but my search is over - I will not hesitate to call Radiant next time and would recommend them unreservedly.

8/9/23 Update: I have subsequently used Radiant for a toilet repair, faucet installation (Danny), and drain work (Ezekiel) and they have continued to impress with knowledgeable, friendly plumbers and quality work.
