How it works
What to expect, start to finish
1. Initial Radon Test Review and Home Walkthrough
We start by looking at your radon test results and walking the property, whether it's a rowhome in Downtown York, a older stone-and-brick property in West York, or a newer build near Spring Garden Township. York County sits on limestone and fractured bedrock in many areas, which lets soil gas move more freely into basements and crawlspaces, so we check foundation type, sump pit location, crawlspace access, and any cracks or utility penetrations before recommending a system.
2. Upfront Quote and System Design
Based on the walkthrough, we design a sub-slab or sub-membrane depressurization system suited to your foundation. Homes in East York and North York with older poured basements often need a different pipe routing than the split-level and crawlspace homes common in Devers and Pinehurst. You get a clear, written quote before any work starts, no surprise add-ons.
3. Installation Day
Most installs take a single day. We core through the slab or seal the crawlspace membrane, run PVC piping vertically through an interior closet or up an exterior wall, and install a quiet inline fan. We seal all sump lids, floor cracks, and openings that could let soil gas bypass the system, which matters more here given York's cold winters that keep basements sealed up tight for months and can concentrate radon indoors.
4. Fan Startup and Pressure Check
Once the fan is running, we verify the system is pulling negative pressure under the slab or membrane using a manometer, and we walk you through the U-tube gauge so you can visually confirm the fan is working going forward.
5. Post-Mitigation Retest Guidance
We recommend a follow-up radon test 2-3 days after installation to confirm levels have dropped, and we're happy to point you toward test kits or short-term monitors so you have documented before-and-after numbers for your own records or for a home sale.
