"Mean hourly" is the BLS OEWS state-level cross-industry mean wage paid to the worker. Loaded billing rate is a typical 2.4× multiple used in residential bids to cover overhead, insurance, taxes, vehicle, and contractor margin. Use it as a sanity check on a quoted hourly rate.
Best Months to Schedule Exterior painting in Chicago, IL
Derived from NOAA climate normals for IL: heating/cooling degree days, freeze months, and annual precipitation.
Why these months
Latex paints cure best between roughly 50–85°F with low humidity. Hot humid summers and cold winters with strong seasonal swings narrows the ideal cure window to these months.
Booking tip
Schedule exterior paint at least 24 hours after the last rain and avoid days with heavy dew.

Average Cost in Chicago, IL
For a typical radon mitigation scenario in Chicago, IL, this calculator currently models a total around $1,821.
When budgeting Radon Mitigation in Chicago, local quotes usually reflect conditions across Illinois. Downstate Illinois pricing differs from Chicagoland by 20-40% for similar scopes, reflecting labor-market and density differences.
Chicago is a large metro where contractor availability and permit volume can move pricing and lead times as much as material choices.
Home improvement quotes near Chicago, IL are most sensitive to scope clarity, access, and which finishes are included versus "allowance only."
Local conditions in Chicago, IL include hot humid summers and cold winters with strong seasonal swings, which often shows up in material choices and scheduling.
Illinois's housing stock skews to older brick and frame housing with mature urban cores, which gives Chicago contractors a fairly consistent set of structural and finish patterns to bid against.
In Chicago, modeled costs are currently about 8% below the national baseline. That usually reflects a mix of large-metro labor pricing, subcontractor availability, and broader midwest regional cost pressure.
Local labor conditions, permit timing, and finish selection all influence how this project prices in Chicago.
Low / Mid / High Project Scenarios
Low Scenario
$1,069Single-point passive system on a slab home with existing outlet.
Mid Scenario
$1,829Active sub-slab depressurization on a basement with one suction point and short-term post-test.
High Scenario
$4,857Sub-membrane crawl-space system on a split-level with three suction points, premium fan, and continuous monitor.
What Changes the Estimate Most in Chicago?
- Foundation type sets the baseline: slab is cheapest, basement is mid-range, and crawl space requires sub-membrane work that costs more.
- Number of suction points is driven by foundation complexity — split-level and large homes commonly need 2–3 points.
- Fan grade and electrical work (existing outlet vs new circuit) account for $200–700 of variation between similar systems.
When This Calculator Is Less Accurate
This calculator is less accurate when the home has multiple disconnected foundations, sub-slab voids that require sealing before depressurization, very high baseline radon (>20 pCi/L) needing multi-fan or HRV-integrated systems, or commercial-scale buildings.
Use the result as a budgeting starting point, then validate with local contractor quotes if the scope includes specialty materials, hidden damage, or permit-driven design changes.
How Much Does Radon Mitigation Cost in Chicago?
A residential radon mitigation system typically costs $800–3,000 installed, depending on foundation type, system style, number of suction points, fan grade, and electrical work. Active sub-slab depressurization on a single-foundation slab home is on the low end; sub-membrane crawl-space systems and drain-tile or sump-integrated designs cost more. EPA Zone 1 areas (most of the Midwest, Appalachia, Mountain West) see the highest demand.
Cost Factors:
- Foundation type — slab is cheapest, basements are mid-range, and crawl spaces or split-levels cost more
- System type — passive systems are cheaper but less effective; active sub-slab depressurization is the standard
- Suction points — single-point systems cover most homes; complex foundations need multiple points at ~$350 each
- Fan grade — standard, high-suction, and ultra-quiet premium fans span a 2× range
- Electrical and venting routing — new outlets, attic runs, and rooftop terminations add labor time
In Chicago, home improvement costs are 8% below the national average. This reflects local labor rates, material availability, and cost of living in the Chicago metro area.
Frequently Asked Questions (5)
How localized is the Radon Mitigation estimate for Chicago, IL?
This page applies a Midwest regional cost model plus local signals for Chicago, IL, so totals are modeled around 8% below a national baseline before you change inputs. Use it as a budgeting range, then compare written quotes for your exact scope.
What should I verify with contractors in Chicago?
Confirm permits, HOA or historic-district rules, material lead times, and whether demolition or hidden damage is included. Illinois codes and local inspection steps can change both price and schedule compared with national averages.
How much does a radon mitigation system cost?
Most active radon mitigation systems cost $800–3,000 installed. A simple single-suction-point system on a slab or basement runs $900–1,500, crawl-space sub-membrane systems land $1,800–3,000, and complex multi-point installations on split-level homes can reach $3,500–5,000.
Do I need a radon mitigation system?
The EPA recommends action when indoor radon levels are 4 pCi/L or higher; many health authorities recommend mitigation above 2 pCi/L. Test your home — short-term radon test kits cost $20–40, and any home in EPA Zone 1 should be tested every few years and after major foundation work.
How long does a radon mitigation system last?
The PVC venting and sealing typically lasts 20+ years. The radon fan itself is the wear item, with a lifespan of about 5–10 years for standard models and 10–15 for premium ultra-quiet units. Most systems include a manometer that lets homeowners monitor function at a glance.
Data sources & methodology
Estimates blend national base costs, the BLS residential construction PPI, regional and direct metro CPI series, BLS OEWS state labor wages, and U.S. Census ACS housing signals. Market data refreshed April 2026. Expect ±15–30% spread vs an actual contractor quote.
