What a radon system does
Keep your test result and its date. Ask the company where the fan and the vent pipe will go, and whether it retests once the system is running.
An installed radon system in Texas: our estimate
We put an installed system at $840 to $1,900 per system, installed. The model starts from one national published range, widens it 15 percent each side and applies the Texas construction laborer wage ratio. No Texas company price is in it, and it isn't a quote.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $840 to $1,900 per system, installed | Built from one national published range, adjusted by the Texas construction laborer wage ratio (0.82). Ten Texas foundation companies publish a price we could count on their own websites; where five or more price the same job, the range is the middle half of their prices, and where two to four do, the estimate is widened to take them in. Coupons, specials and figures a page gives as an average are not counted. Basis: no state company sample (no counted Texas company price for this job), national estimate only. |
| Mean wage in Texas, construction laborers | $20.63 an hour | BLS May 2025 hourly mean for the occupation nearest to radon installers; pay, not a price. |
| Mean wage nationwide, construction laborers | $25.02 an hour | National hourly mean from the same release; Texas over US is the ratio. |
Estimated range. Built from national published ranges (1 source), adjusted by Texas's construction laborer wage ratio to the US (0.82, BLS May 2025). Not a quote. Ten Texas foundation companies publish a price we could count on their own websites; where five or more price the same job, the range is the middle half of their prices, and where two to four do, the estimate is widened to take them in. Coupons, specials and figures a page gives as an average are not counted. We have no counted Texas company price for this job, so the range is our national estimate alone. Full method. Prices as of Oct 23, 2026.
Radon-adjacent problems that can't wait
- A gas smell in the house means get out first, then phone 911 and your gas company.
- There's water around the fan or its wiring; keep clear of it.
- A test result you want to compare across companies before buying a system.
Before you hire a radon company
- Get a test and keep the written result with its date.
- Ask each company what result would lead it to recommend a system.
- Ask what it does if the reading is still high once the fan runs.
Permit position for a radon system
Ask your building office whether the fan's electrical connection needs a permit before the system goes in.
Texas has no state license for foundation repair, so ask for the contractor's certificate of insurance and call the insurer listed on it before you sign anything.
