Our Plumbing Services in Allen
Emergency plumbing first, because that's the core of the company: somebody picks up at three in the morning and on Christmas, and a pipe spraying in a wall gets a truck right then. The emergency fee is said on that call, before anybody drives.
Water heater repair and replacement, and with it expansion tank replacement when the small tank above the heater has filled with water. PRV replacement is next: the valve in the flower bed that holds the house too low or lets it run too high. Water leak detection is for a wet floor nobody can explain. Slab leak repair is the copper under the slab; water line repair is the copper out in the yard.
Drain cleaning clears a kitchen line, a bathroom sink or shower, or a toilet a plunger can't. Sewer line repair and camera inspection is for the main line that backs up and keeps doing it. The rest of the house: toilet repair, faucet repair, shower valve repair, hose bib repair (hose bibb, if that's how you spell it) for the spigot on the wall, garbage disposal repair.
Water Heaters in Allen: Past Ten Years, in the Attic or the Garage
Ten years is what a tank gives you, and a lot of Allen houses are past that. Attic or garage, the replacement has the same parts: the tank, a pan piped out of the house, the T&P discharge line, the expansion tank, the gas sediment trap, the vent. The City of Allen wants a permit for a water heater replacement and a Water Heater Final inspection after it, and we file the permit and book the inspection.
The attic water heater after the home inspection, 2026. A family bought a house in Allen, hired a home inspector, and he went through the house and said everything's fine. Then we went up in the attic. An old gas water heater with the T&P valve not connected to anything, no discharge line at all. The two PEX supply lines screwed straight onto the top of the heater, no distance from the tank, which you can't do with PEX on a gas heater, and under the pressure the PEX had bent down in an arc like a rainbow. How it hadn't burst and flooded the whole house, nobody knows. We replaced the heater, did everything to code, and the city inspection passed. We've seen this in Allen before.
The garage water heater on a single wall vent. Another Allen replacement. The vent pipe in the garage was single wall, not B vent, and there was no expansion tank at all. We put in the new water heater with the expansion tank and the gas sediment trap, connected the T&P valve properly, and ran a new B vent all the way out through the roof, so there's no carbon monoxide question in that garage. It passed the inspection. If you smell gas, leave the house first. Then call the gas company, or call 911 for the fire department.
Water Pressure in Allen: the PRV Nobody Can Find
In Allen the pressure reducing valve is usually buried, and not under mulch: under dirt, two feet of it in one house we dug. Twenty years ago the box sat at ground level. Then the ground moves, the rains come, the box silts over and fills with dirt, and that's how a valve gets buried. The homeowner doesn't know it's there. The symptom is what brings us: the gauge on the hose bib reads 90 PSI and drops to almost nothing once the water is running, or the whole house sits at 30. Both are the same valve. Over 80 PSI it gets replaced and set to 70, or lower when the homeowner asks for it; a valve that reads fine standing still and collapses under flow gets replaced too.
90 PSI, and the valve two feet down. About 90 PSI on the gauge, and when the water was running it fell to almost nothing. We measured, traced the line, and dug: the PRV and the second shut-off valve were about 70 centimeters down, well over two feet. The old valve came out, a new PRV and a new shut-off valve went in, the permit was pulled and the city inspection passed. The house is past 35 years, and the homeowner asked for 60 PSI and not a drop more, because the pipes are old and he didn't want the strain. So it's 60, and the pressure doesn't drop or jump when a faucet opens.
30 PSI, and a valve the homeowner didn't know he had. The call was low water pressure, down to 30 PSI. We measured, ran the diagnosis, and found the PRV and the second shut-off valve buried deep in the bed, the homeowner had never seen either. The old valve came out, the new one went in, the pressure was set to 70, and the house came back. The water here is hard, like everywhere around us, and hard water is what clogs a PRV and wears it out.
Main Water Line Repair in Allen
The pipe between the meter and the house belongs to you, and in the older streets of Allen it's copper in clay. Clay swells in a wet winter and shrinks in a dry summer, the copper moves with it and wears thin, and one day there's a pinhole. A patch of yard that stays wet, or the meter creeping with every tap closed: that's the line. The City of Allen bills the water that goes through a leak on your side of the meter, whatever the reason, so a yard leak here is worth finding early. We locate the line before anyone digs; the water line repair page shows how.
Clogged Drains and Sewer Lines in Allen: Roots, and a Toilet That Clogged Twice
The soil moves, a joint in the main sewer line separates, dirt and roots get in, and the line clogs. The chain snake goes in through the outside cleanout and opens it, and the camera follows to show where the dirt got in. Opening the line is the first step, not the repair. The separated section gets dug up and replaced, in the yard, or under the house through a tunnel when that's where it is.
The main line in the yard. Another Allen main line clogged in the yard: the ground had moved, the pipe had separated, and dirt and roots had come in. We cleared it with the chain snake through the outside cleanout and the house drained. That's a temporary fix, and we said so: it gives the homeowner time to plan the budget for replacing that section. A line like that clogs again, and if it happens while nobody's home and the washer or the dishwasher is running, that's a backup and a flooded house.
The toilet that clogged twice. A clogged toilet in Allen. We cleared it with the small local snake, the toilet flushed, and the plumber said he felt something else down there and offered to run the camera. The homeowner said leave it, if it happens it happens. Two days later it clogged again. This time we pulled the toilet and ran the camera: the branch line under the house had separated and roots were growing in through the gap. We dug small tunnels under the slab and replaced that section of pipe. When the plumber says he has a feeling about the line and wants the camera in it, that feeling is worth the hour.
Roots at the tree, and the flange under the toilet. The main line was backing up, everything in the house, and water was seeping from under a toilet. We cleared the main line with the chain snake, deep, and pulled the roots out; the camera showed the separation right by a tree in the yard, the tree had grown into the pipe and broken it. That restored the flow. The toilet still seeped a little at every flush and rocked, so we pulled it: the wax ring was dead and the flange under it had rusted away. We put in a new flange and a new wax ring and set the toilet back, and it stopped leaking and stopped rocking. The repair of the main line in the yard went on the schedule after that.
Leaks Inside the Walls: a Corroded Fitting on a 3/4 Line
The fitting in the wall, an emergency call. An Allen house started getting wet, the floor first, then properly squishy. We ran leak detection and opened the drywall: the 3/4 copper line with a fitting on it, somebody's work from years back, maybe the builder's, and the fitting itself had corroded through and was spraying. It wasn't a drip, it was going hard. We cut out that section, fitting and all, and put in good copper, and the leak was done. Good thing the call came when it did; the house got wet, not flooded. That's what water leak detection is for: the wall is opened where the leak is, not where the water shows.
Outside Spigots in Allen, and the One Soldered Straight to the Pipe
A frost free spigot on the wall sits on a threaded connection inside the wall, the connection is secured, and when the spigot fails you unscrew it from outside and put on a new one. That's how it's built so it can be serviced.
The spigot with no connection. An Allen house past thirty years. The spigot was frost free and not that old, and it stopped working. We started unscrewing it from outside, the way it's always done, and the plumber felt something wasn't right. So we went around to the inside and opened the drywall: no threaded connection at all, the pipe was soldered straight into the spigot. To change it you have to open the wall and resolder, or you break the pipe. We opened the wall, put in a proper threaded connection, and set it up so the next time anything happens to that spigot it unscrews from outside like it should. Who did it that way, the builder or a plumber before us, there's no telling. A spigot is a part you replace, not a project.
What the City of Allen Asks of a Plumber, and What’s Yours to Keep
The City of Allen registers plumbing contractors before it issues them permits, and FPP is registered. A water heater replacement gets a permit and the city's Water Heater Final inspection. A water or sewer repair under the slab gets its own inspection: the city wants the pipe photographed and the sewer line tested with water before the tunnel is filled. Stopping a leak or clearing a clog takes no permit, and we don't pretend it does.
The split is at the meter. The city owns the main and the meter; everything after the meter is yours, and the city's rule is that water lost through a leak on your side goes on your bill, whatever caused it. The sewer line is yours from the house to the cleanout at the property line; from there to the main it's the city's. Houses built after 1997 have that cleanout; if yours doesn't, the city installs one.
You can close the water at the meter yourself in Allen, with a meter key, when a pipe bursts and your own shut-off valve won't turn; the city says so on its own pages. Finding your own valve on a calm day is still the better plan, and the guide on how to shut off the main water valve shows where it sits in a house like yours.
Emergency Plumber in Allen: Night Calls From Two Offices
Allen gets night service from both offices, Plano and Frisco: whichever truck is on call comes. The person who answers asks what's happening and talks you to the right valve while the plumber drives. The corroded fitting in the wall was one of those calls.
Water you can't stop is an emergency. So is a sewer line backing up, a tank that let go in the attic, a pipe split by a freeze. A dripping spigot or a slow sink is a weekday job, and the person on the phone will say so instead of sending a truck at the night rate.
Nights, weekends and holidays carry an emergency fee tied to the hour, named before the truck leaves. The emergency plumbing page walks through a night call step by step.
How a Plumbing Call in Allen Goes, From the Phone to the Invoice
Weekdays, $49 gets the truck to the house and the problem found, and the $49 is credited to the repair when you approve it. The whole price is named before the work, and the invoice is that number. If we have time open, we come the same day. The six steps in full are laid out on the homepage.
Every shift has two plumbers, and the common parts ride along, so the job gets finished in one visit when the part is the problem. Payment is after the work, in whatever form you keep: card, Apple Pay, PayPal, Zelle, Venmo, check or cash. Zelle, check and cash are the plain price; a card costs a little more, because the card company takes its cut, and we say so before you tap. Pay over time is there too, through PayPal Pay Later or Klarna at checkout.
Allen Plumbing FAQ
What does a plumber cost in Allen, TX?
$49 on a weekday for the service call, credited to the repair if you go ahead. The repair itself is one flat number, said before the work and printed the same on the invoice. Nights, weekends and holidays add an emergency fee tied to the hour, named on the phone first.
Which office sends the plumber to Allen?
Both. Allen sits between Plano and Frisco, and the call rings on both offices at once; the truck that's free comes. The two numbers are at the top, and either one reaches the same people.
My PRV is buried and I can't find it. Can you?
Yes, that's most Allen calls about pressure. We trace the line from the meter toward the house and dig where the valve has to be; one in Allen was about two feet down. The new one goes in with a valve box, so the next plumber finds it without a shovel.
Does the City of Allen inspect a water heater replacement?
Yes. It takes a permit from the city and a Water Heater Final inspection, and the inspector looks at the vent and at where the T&P discharge line goes. We register with the city, file the permit and book the inspection; it's part of the job, not an extra.
The main line was cleared and backed up again. Is that the roots?
Usually it's the gap the roots came in through. Clearing cuts the roots; the separated joint or the broken section is still there, and the roots grow back through it. The camera shows where the gap is, and that section gets dug up and replaced, in the yard or under the house through a tunnel.
Who pays for the water lost through a leak on my side of the meter in Allen?
You do. The city's ordinance puts the water that goes through a leak on your side of the meter on your bill, whatever the cause. That's the reason to call when the meter turns with everything off, not when the yard turns into a pond.
Can I shut the water off at the meter myself in Allen?
Yes. The city allows a homeowner to close the valve at the meter with a meter key when a pipe bursts and the valve at the house won't turn. The key is a few dollars at any hardware store. Better still, find your own main shut-off valve on a calm day; the guide at the top of the city section shows where it usually sits.

Very professional and stayed until the job was done. Installed a new hot water heater for me and made it better than it looked before.

I had a great experience with two jobs. I needed a new valve box installed in the laundry room and one outside sillcock was leaking. I was a little nervous when I saw a blowtorch but everything is water tight and working. I definitely will call them back if I need anything else done!

Was able to fit us in the same day and correctly fix the issues (leaking shower faucet and exterior broken pipe) and answer all questions. Will plan to use again for future plumbing needs

Great work, reasonable and responsive. He came out late on a Sunday to clear a clogged pipe that had to get fixed. I would definitely use again.
