Foundation Crack Sealing
Seal the Gaps, Protect Your Home!
Even the smallest crack in a concrete foundation can act like a doorway for radon gas, moisture, and soil vapors. Left unsealed, these gaps give radon an easy path into your living space. Foundation crack sealing is one of the most effective ways to close these leaks and support a healthier home environment.
Why Cracks Are a Problem
Concrete is durable, but it isn’t immune to change. Natural settling, shifting soils, or temperature swings can create cracks over time. While most cracks don’t endanger your home’s structure, they do create openings you don’t want. Imagine your basement floor with invisible straws poking through the ground — that’s how radon slips inside.
Radon can’t be seen, smelled, or tasted, which makes closing these pathways all the more important. By sealing cracks, you’re cutting off radon entry before it builds up to unhealthy levels indoors.
How BreatheWell Seals Cracks
Our team uses radon-resistant sealants that are stronger and longer-lasting than store-bought caulks. These products remain flexible, so when your foundation shifts slightly with the seasons, the seal stays intact.
Our approach includes:
- Detailed inspection: Locating cracks in floors, walls, and slab joints.
- Surface preparation: Cleaning and prepping the crack for maximum bond strength.
- Application: Filling gaps with radon-rated sealant for a tight, durable finish.
- System support: Pairing sealing with your mitigation system for maximum effectiveness.
The Advantages of Crack Sealing
- Closes hidden radon entry points
- Helps keep basements drier and fresher
- Boosts the efficiency of radon mitigation systems
- Provides added peace of mind for homeowners

Foundation Crack Sealing FAQ
Can sealing cracks lower radon levels?
Yes, sealing prevents radon from sneaking in through open pathways. While sealing alone usually isn’t enough to solve the problem, it’s an essential part of a complete mitigation plan.
Is this the same as repairing my foundation?
No. Crack sealing blocks radon and moisture but isn’t a structural repair. If a crack affects the strength of your foundation, a structural contractor should be involved.
How durable is the seal?
The sealants we use are made to last. They stay flexible and bonded even as your foundation naturally moves with soil or weather changes.
Should every crack be sealed?
We focus on cracks that cut all the way through the slab or wall, since those are the ones that let radon pass. Cosmetic surface lines may not need sealing.
Can crack sealing replace a mitigation system?
Not usually. Radon can still seep in through pores in the concrete or other entry points. Sealing works best when combined with an active mitigation system to ensure safe levels.
