As a trusted partner to leading manufacturers, certified installers, cities, and school districts, we deliver rigorous, detail-driven assessments that ensure every play environment meets the highest standards of safety and quality. From school campuses and women and children's shelters to indoor playgrounds and creative learning centers, our evaluations cover equipment integrity, surfacing performance, environmental health, and overall site design. With decades of experience and strong industry partnerships, Cornerstone Kids helps communities reduce risk, strengthen compliance, and create vibrant, secure spaces where children can explore, grow, and thrive.
Inspections & Audits
We provide the following services for indoor and outdoor playgrounds and play systems.
A complete, standards-based review of your playground — equipment, surfacing, layout, and site conditions — in alignment with ASTM F1487 and CPSC guidelines. Clear, photo-documented report with hazards ranked by priority.
We identify entrapment, protrusion, fall, and entanglement hazards, then translate them into a plain-language action plan that reduces injury risk and liability exposure.
A great playground is one every child can use. We evaluate accessible routes, transfer points, ground surfaces, and play components against ADA and ABA standards, and map a realistic path to compliance.
Buying or taking over a property with existing play equipment? Get an independent condition and compliance assessment before you commit.
When your community reports damaged equipment, worn surfacing, or a safety hazard, we respond quickly and document the fix. Fast, responsible follow-through prevents injuries, keeps your site compliant, and shows families their concerns lead to real action.
Before children start using a newly built playground, get an independent, expert review of the whole site. We verify equipment is installed correctly, surfacing meets safety standards, and the build aligns with current regulations and manufacturer specs.
An unfinished playground site needs protection too. We assess your construction site and recommend measures to prevent vandalism, keep people out of wet concrete and unfinished surfacing, and reduce the risk of injury to anyone who wanders into an active work zone.
A Twin Cities Playsafe Service
Some things you can't see by looking. Twin Cities Playsafe provides instrument-based testing that measures how a playground actually performs — how hard the surface hits in a fall, and how clean the equipment really is.
Protective surfacing is your last line of defense in a fall, and it degrades with weather, wear, and compaction. We field-test impact attenuation in alignment with {{CONFIRM: ASTM F3313 / ASTM F1292 — owner to confirm which standard the field procedure follows}}, measuring Gmax and HIC against your equipment's critical fall height — so you know whether the surface still protects.
New site? Have your installer include an independent surfacing assessment in their bid — before final payment. Third party telling you it's time to replace your surfacing due to age? Test it independently first to see where it really stands in its lifecycle.
A full-site assessment looks past the equipment to the real-world risks families care about — sightlines for supervision, layout issues that could contribute to conflict, and hazards that could lead to injury. We also review staff readiness and emergency response, so your site is prepared to act quickly if something happens.
High-touch play surfaces collect organic residue over time. Using ATP bioluminescence swabs, we measure surface cleanliness and verify that cleaning routines are actually working — especially valuable for indoor play areas, daycares, and high-traffic equipment.
ATP testing measures organic residue as a hygiene indicator; it does not identify specific pathogens.
Some contamination lives in the air, not just on surfaces. We place incubation samples on-site to collect airborne spores, then culture them for about a week to quantify the mold and bacteria present — giving indoor play areas, daycares, and other enclosed spaces a clear read on air quality alongside our surface testing.
Air sampling quantifies mold & bacteria spore counts; a qualified professional should interpret results for any remediation decision.

For Parents & Caregivers
Parents want to know the places their children play are genuinely safe, clean, and well-maintained — and that's exactly why independent playground testing matters.

It gives families peace of mind, confirms the environment is healthy, and ensures the playground is truly ready for safe, joyful play. It's a simple step that protects children and reassures parents that their concerns are taken seriously.
