Your neighbor's number tells you little about yours, so a 48-hour test is the only way to know. ac\_unit ### Winter makes it worse When the furnace runs and the ground freezes, warm air rises out of the house and pulls soil gas in through the slab, sump and cracks. real\_estate\_agent ### High results stall closings A failed radon test during inspection can hold up a sale. We test inside your contingency window and can install and verify a system before closing.

From our office we use I-235 and US-65 or I-80 to reach neighborhoods near Adventureland, Prairie Meadows and Spring Creek. With so many homes changing hands and new subdivisions going up, we keep testing slots open for real estate deadlines and post-construction tests. Call any time to book. Local homes ### Newer Homes and Established Neighborhoods **Builder passive systems.** Many newer Altoona homes have a passive radon pipe from the slab to the roof. It's a good start, but it often needs an attic fan to bring levels below 4.0 pCi/L. A post-construction test settles it. **Established homes.** Older neighborhoods near downtown Altoona have basements that often benefit from a standard sub-slab system with sump and crack sealing. **Finished lower levels.** Many owners finish basements soon after buying. Testing before the walls go up makes any install easier. ### Local facts that shape the job - fact\_check Altoona is in Polk County and uses ZIP code 50009.

Many homes here were built during the 1960s and 1970s growth spurt and have open sumps and settled slabs. ### Do new homes near Spring Creek need radon testing? expand\_more Yes. Newer homes can test high, with or without a builder passive pipe. A 48-hour test after move-in tells you your level, and a passive pipe can be activated with an attic fan if needed. ### Do you serve neighborhoods near Adventureland and Prairie Meadows? expand\_more Yes. We reach them on I-80 and US Route 65, along with Spring Creek, the Haines Park area, downtown and northeast Altoona. ### Should I test before finishing my basement? expand\_more Yes.
