Radon Mitigation Problems in Altoona Basements
The local problem
Open sumps and cracked floors in 1960s and 1970s Altoona basements
What you notice: An older basement tests high, the sump pit is open and the floor has hairline cracks along the walls.
Why it happens here: Altoona's population nearly quadrupled between 1960 and 1980, so a large share of homes near downtown and Haines Park are 45 to 65 years old, with open sumps and settled slabs.
How we fix it: Residential radon mitigation here pairs a sub-slab suction point with an airtight sump lid and sealing of cracks and the floor-wall joint.
Every Iowa county is EPA Zone 1
About 71% of Iowa homes test above the EPA action level of 4.0 pCi/L. Your neighbor's number tells you little about yours, so a 48-hour test is the only way to know.
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.
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.

Reviews From Local Homeowners
"We assumed our Altoona home was radon proof because of the pipe. The test said otherwise. The fan went in quickly and the retest came back low."
"Tested before finishing the basement. They installed the system while the walls were open. Smart move."
"Friendly, fast and they answered every question on the phone before the visit."

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.

Altoona Radon Questions, Answered
What system do older basements near downtown Altoona need?
Most need sub-slab depressurization with sealing of the sump, floor cracks and floor-wall joint. 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?
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?
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?
Yes. Many owners finish lower levels soon after buying. Installing a system is easier while walls are open, and a retest after the finish work confirms the result.
