Plumbing Contractors government contracts in South Carolina
The federal government has already bought plumbing work in South Carolina, and every one of those contracts is public record — filed under NAICS 238220, a code it shares with HVAC. Below is what our copy of that record says about the plumbing side of it: who won, which agencies bought, what the awards were worth, and which contract terms run out soon. Each row was selected by reading its own work description, and the ones we could not read confidently are counted rather than claimed.

South Carolina place of performance — one code covering plumbing and HVAC
Across the 41 of 413 awards on record under this code whose work description reads as plumbing work
Of the 413 descriptions we read — our reading of the text, not a federal classification
Open under NAICS 238220 in South Carolina — both trades, split further below
How to read this page: NAICS 238220 is titled "Plumbing, Heating, and Air-Conditioning Contractors" — the federal government files plumbing and HVAC under one code and does not separate them. This page is a filtered view of that code: we read each record's own work description and show the plumbing ones. 41 of the 413 awards we read describe plumbing work, and 161 describe both trades or say too little either way — those appear in no ranking on this page or on the HVAC one. How the split works · 238220 in South Carolina with no work-description filter
How this page separates plumbing from HVAC
It does not separate them by NAICS, because NAICS cannot. The U.S. Census Bureau gives 238220 the title "Plumbing, Heating, and Air-Conditioning Contractors" — one code, both trades, deliberately. A contracting officer filing a sewer-line repair and one filing a chiller replacement use the same six digits, and no field in the federal record tells the two apart.
So this page reads the work description on each record and keeps the ones that describe plumbing work. The words it reads as plumbing: plumbing, piping, water line, sewer, drain, backflow, plumbing fixture, water heater, lift station. Words that are excluded from a scope — "no plumbing work is included", "plumbing by others" — do not count as signals.
Where the text says both trades, or says neither clearly enough, this page claims nothing. Those rows are counted in the table beside this and then left out of every ranking here and on the HVAC page. A missed contract costs this page one row; a wrongly claimed one would tell you something false about who is winning your work.
This filter is our reading of published text. It is not a federal classification, and the government does not maintain one for these two trades.

The agencies buying plumbing contractors in South Carolina
Knowing which agency actually spends the money in your state tells you whose forecast to read, whose industry days to attend, and whose small-business specialist to call. Counts and dollars are across the 41 of 413 awards on record under this code whose work description reads as plumbing work. The table is ranked by reported dollars, which is not the same order as how often an agency buys — one large contract can outrank a buyer that awards small jobs every month, so read the awards column too.

South Carolina plumbing contractors contracts whose term ends within a year
The period of performance on these awards currently ends in the next twelve months. That is a signal worth watching, not a promise: many contracts carry option years the agency can exercise, which pushes the end date out without any new competition. Only awards this page reads as plumbing work are listed; the HVAC side of 238220 has its own radar on its own page.
| Current end date | Incumbent | Agency | Amount |
|---|---|---|---|

The NAICS codes plumbing contractors work is bought under
A federal solicitation carries exactly one NAICS code, and that code decides two things at once: whether the bid reaches your feed, and what size standard you have to be under to bid it as a small business. Award counts are across the 41 of 413 awards on record under this code whose work description reads as plumbing work.
| NAICS | Industry | SBA size standard | Awards | Reported total |
|---|---|---|---|---|
| 238220 | Plumbing, Heating, and Air-Conditioning Contractors | NAICS 238 family standard: $19.0M average annual receiptsNot 238220's own published figure | 41 | $3,536,761 |
Industry titles are the official 2022 U.S. Census NAICS titles. Size standards come from our seed of the SBA table at 13 CFR 121.201. Where that seed lists the six-digit code itself, the figure shown is that code's own published standard. Where it does not, the row says so and shows the figure published for the NAICS family the code sits in — that is the family's number, not this code's, and sibling industries do not always share one. A blank means the seed carries neither, never that no standard applies. Confirm the code's own line in the current SBA table before you certify anything. The award columns count only the rows this page reads as plumbing work. The code's own count — 413 awards, both trades — is in the panel above.

Past plumbing solicitations in South Carolina
Solicitations whose deadline has passed. You cannot bid these, and every page says so at the top — but the scope, the requirements and the issuing office are still there to read, which is the cheapest preparation there is for the next time the same agency buys the same work.
We hold no closed plumbing contractors solicitations for South Carolina yet. The archive fills as the bids we track pass their deadlines — an empty archive here means our record is young, not that nothing has ever been solicited.
How to use South Carolina award history to win the next contract
Award records tell you who you are really bidding against
A solicitation tells you what an agency wants. The award record tells you what it has actually been willing to pay, and to whom. Before you price a South Carolina job, read the incumbent table above: if one company holds most of the awards under your NAICS code, you are bidding against an incumbent with past performance the evaluators already trust, and your proposal has to give them a reason to switch.
What the plumbing half of 238220 looks like
The plumbing work that reaches this code is mostly repair and replacement rather than new construction: water and sewer lines, interior piping, drains, backflow-prevention assemblies, restroom fixtures, water heaters and lift stations. Because the code is shared with mechanical work, the code is never enough to tell you whether a solicitation is yours — read the statement of work. Two things worth checking before you price a job: whether the specification names a plumbing code the site is inspected against, and whether the work touches a potable-water system, which usually drags certification and permit requirements along with it.
Period-of-performance end dates are your calendar
Most services work is re-competed near the end of its term. An award whose current end date lands in the next twelve months is the earliest honest signal that a new solicitation may be coming — early enough to introduce yourself to the contracting office, request a copy of the current statement of work, and be a known name when the notice posts. It is only a signal: option years exist, and agencies exercise them.
One NAICS code decides whether you count as small
Each solicitation names a single NAICS code, and the SBA size standard attached to that code is the line between bidding as a small business and bidding open. The table above shows what our seed of the SBA table holds: for some codes the code's own published figure, and for the rest only the figure published for its NAICS family, which those rows label as such. A family figure is a rough bearing, not the threshold you certify against — check your own average annual receipts against the code's own line in 13 CFR 121.201 before you self-certify. A wrong certification is the kind of mistake that gets a proposal thrown out after you have already done the work of writing it.
Prevailing wages on federal construction
Federally funded construction contracts over $2,000 carry Davis-Bacon Act prevailing wage requirements: the wage determination attached to the solicitation sets the minimum hourly rate and fringe benefits you must pay by trade classification and by county. Those rates go into your bid before your margin does, and they vary within South Carolina — price from the determination attached to the specific solicitation, not from a state average. Our free wage-determination tool points you at the official figures.

South Carolina plumbing contractors contracts — common questions
- How many federal plumbing contractors contracts have been awarded in South Carolina?
- We hold 413 federal contract awards with a South Carolina place of performance under NAICS 238220, which covers plumbing and HVAC together. Of the 413 we read in full, 41 describe plumbing work, with periods of performance starting between Jun 23, 2016 and Jul 16, 2026. The remaining 372 either describe HVAC work or do not say clearly enough for us to claim them.
- Which NAICS codes cover plumbing contractors government work?
- One: 238220. Its official U.S. Census title is "Plumbing, Heating, and Air-Conditioning Contractors", so plumbing and HVAC are filed under the same six digits and the code alone cannot tell them apart. That is why this page is a filtered view of 238220 rather than a separate code — we read each record's own work description. The federal government does not classify the two trades separately, and nothing on this page should be read as saying it does.
- Who buys plumbing contractors services in South Carolina?
- Across the 41 of 413 awards on record under this code whose work description reads as plumbing work, the agencies that bought most often are Department of Veterans Affairs, Department of Defense, Department of Homeland Security. That is by number of awards; the table on this page ranks the same agencies by reported dollars, which can put a different name first when one large contract outweighs many small ones.
- Are there open plumbing contractors bids in South Carolina right now?
- Not at this moment. Open solicitations turn over constantly; the free weekly digest emails you the new ones for this trade instead of making you re-check.
- If plumbing and HVAC share one NAICS code, how is this page plumbing only?
- It is not a separate code — it is a filter, and we would rather tell you that than let you assume otherwise. Every award and solicitation under 238220 here is read for what its own description says: plumbing, piping, water line, sewer, drain, backflow, plumbing fixture, water heater, lift station. 161 of the 413 awards we read describe both trades or say too little either way; those are counted here but kept out of every ranking on the page. The same records with no work-description filter are on the South Carolina construction-trades page.
- Does a backflow certification matter for federal plumbing work?
- Often, and it is set locally rather than federally: backflow-prevention assembly testers are certified by the state or by the water purveyor whose system the building sits on, so the requirement follows the job site, not the agency. The solicitation states which certifications it requires — read that list before you price the job, because a tester certification you do not hold is not something you can obtain between the notice and the due date.
