Building Maintenance

Commercial plumbing in Metro Detroit

Scheduled plumbing for commercial buildings across Metro Detroit: restrooms and fixtures, drain and water line repair, water heaters, build-out rough-in. Planned work, done right, on a date you picked.

Straight Answer First

We don't run a midnight truck, and we'll say so now

AGP does scheduled plumbing, not emergency plumbing. If a main breaks at 2 AM and there's water moving across a floor, we're not the number to call, and you should have a 24 hour emergency service in your phone for exactly that. We'd rather tell you today than at midnight.

What we do is the other 95% of a building's plumbing, the part that actually eats a property manager's year: the restroom that's been out of service for a month, the fixtures nobody has replaced since the building opened, the drain that backs up every quarter, the water heater that's clearly on borrowed time, and the full rough-in for a build-out. That work doesn't need to happen at 2 AM. It needs to happen on a date you chose, by people who show up on it.

We self-perform plumbing with our own crews, the same as electrical, HVAC, drywall, paint, framing and roofing, working direct for building owners and property managers across Metro Detroit.

Scope

Plumbing work we take on

Restrooms

Fixtures & restroom work

Toilets, urinals, sinks, faucets, flush valves and carriers. Full restroom renovations where the tile, the partitions, the drywall and the paint come from the same company on the same schedule.

Drains

Drain & sewer line repair

Recurring backups traced to the actual cause instead of cleared and forgotten: clogs, bellies, root intrusion, grease, and the section of line that's failed and needs replacing rather than rodding twice a year.

Supply

Water lines & repiping

Repairs and replacement of supply lines, valves and shutoffs, including the isolation valves your building should have and probably doesn't, so the next repair doesn't take the whole floor offline.

Heat

Water heaters

Commercial water heater replacement and repair, sized to real demand, with the venting and code requirements handled rather than discovered by an inspector.

Turn

Tenant turns & suite work

Relocating fixtures for a new layout, capping and reactivating services between tenants, adding a break room sink or a mop basin where the new lease says one goes.

Rough

Build-out rough-in

Full plumbing rough-in for office and retail build-outs: underground, waste and vent, supply, fixture setting, permits and inspection, sequenced with the framing instead of behind it.

The Real Questions

The backup that keeps coming back

Most commercial drain calls are the same drain. Somebody clears it, it flows, everybody moves on, and it backs up again the next quarter, because clearing a line treats the symptom and tells you nothing about the cause. Meanwhile the building pays for the same visit four times a year and a tenant loses a restroom on each one.

We'd rather find out why. Camera the line, look at what's actually there, and tell you whether it's maintenance, a grease problem that needs a schedule, roots that need a section replaced, or a belly in the pipe that no amount of rodding will ever fix. Sometimes the honest answer is that quarterly clearing genuinely is the cheapest option for your building, and we'll say that too. What we won't do is sell you the same repair four times without ever naming the cause.

Occupied buildings and shutting water off

Water shutdowns hit everybody in a building at once, which makes them a scheduling problem more than a plumbing one. We plan them: which valve, which zone, how long, and what time of day costs your tenants the least, with written notice you can forward. Buildings with no working isolation valves take longer and cost more to work on, so if that's your situation, we'll flag it and price fixing it separately.

Restroom renovations, and why one contractor matters

A restroom renovation is four trades in a small room: plumbing, drywall, paint and finish carpentry, plus tile. Split across four vendors, the schedule is mostly waiting, and the room stays out of service for weeks longer than the work actually takes. We self-perform all of it, so the room is closed once, for as long as the work takes, and then it's open.

What "non-emergency" means in practice

It means we schedule work rather than race to it, and it's worth being precise about the line. A clogged drain, a leaking fixture, a failing water heater or a restroom out of service are all normal scheduled work for us, and we'll get you a date. A burst main, an active flood or a sewage backup in progress is emergency service, and that's a different kind of company with a different kind of on-call rotation. Knowing which one you have is most of the decision, and if you call us and it's the second kind, we'll tell you straight instead of scheduling you for Thursday.

Why It's In House

One contract, one room closed once

The reason we self-perform seven trades isn't a sales point, it's a scheduling one. A restroom renovation split across four vendors spends most of its calendar waiting for the next one to show up, and every one of those days is a room your tenants can't use. Our crews work here, so when the plumbing is done, the drywall is already on site.

Fully licensed and insured. License and insurance documentation comes with the bid, so you're holding it while you're deciding, not chasing it afterward. And every job gets permitted and inspected: a closed permit means the city looked at the work and signed off on it, which is a harder check than anything a contractor can say about itself.

FAQ

Commercial plumbing questions, answered straight

Do you handle emergency plumbing calls?

No. AGP does scheduled plumbing, not 24 hour emergency service. If water is actively moving through your building right now, call an emergency plumber, and keep that number somewhere you can find it at 2 AM. For everything that can be put on a date, we're the better call.

Our drain backs up every few months. Can you stop that?

Usually, but only by finding out why it happens. We camera the line and tell you what's actually there: grease, roots, a failed section or a belly in the pipe. Then you get the real options priced, including the honest possibility that scheduled clearing is genuinely the cheapest answer for your building.

Can you do a full restroom renovation, not just the plumbing?

Yes, and that's where self-performing seven trades pays off. Plumbing, drywall, paint and carpentry all come from us on one schedule, so the restroom closes once instead of sitting out of service between four vendors.

How do you handle shutting the water off in an occupied building?

We plan it: which valve, which zone, how long, and the time of day that costs your tenants least, with written notice you can forward to them. If your building doesn't have working isolation valves, shutdowns get bigger and longer, and we'll flag that and price fixing it as its own item.

Are you licensed for plumbing work, or is it subbed out?

Fully licensed and insured, and the plumbers are ours. You get the license and insurance documentation with the bid, while you're still deciding. We don't publish license numbers on the site for the simple reason that we have several licensed people and that roster changes; the paperwork you get with a bid is always current, and a page is not.

Do you pull plumbing permits?

We do. Permit package, submission, inspections and closeout, the same as our electrical and mechanical work. You're never the one standing in line at a building department for one of our projects.

Do you work as a subcontractor for other general contractors?

No. We work direct for building owners and property managers. That's a deliberate choice: it's what lets us answer for the whole result instead of one scope inside somebody else's schedule.

Put it on the calendar instead of the complaint log.

Tell us what the building needs and when it can't be disrupted, and we'll come back with a date and a number.
