Best for
- Homeowners in DuPage, Kane, and western Cook County suburbs who need same-day response to basement flooding from sump pump failures, burst pipes, or sewer backups.
- Anyone with water-damaged hardwood floors who wants to save the flooring rather than replace it, thanks to Cornerstone's Injectidry and Vortex Drying systems.
- First-time disaster victims who need hand-holding through insurance claims documentation and the restoration process.
- Homeowners needing a mold assessment with thermal imaging and moisture meters before committing to remediation work.
- Commercial properties and institutions needing multi-day restoration projects with a full-time crew.
About this company
Cornerstone Cleaning & Restoration operates out of Lombard, IL, and covers a wide swath of Chicago's western and northwestern suburbs. They started in 2009 as a cleaning and restoration company and hold IICRC certifications including Applied Microbial Remediation Technician (AMRT) credentials. Jason McReynolds owns the company, and Brandon Silva runs day-to-day operations as manager.
What stands out is their hardwood floor drying capability. They use both the Injectidry System and Vortex Drying, which force air beneath flooring to dry it in place rather than requiring replacement. Their free mold assessments include moisture meters and thermal imaging cameras, and they refer clients to an independent environmental hygienist for surface and air testing rather than running those tests in-house. They also handle fire and smoke restoration, sewer backup cleanup, and carpet and upholstery cleaning.
The company has operated since 2009 and holds an A+ rating with the Better Business Bureau. Multiple reviewers mention repeat use over several years, suggesting stable ownership and consistent service quality.
A perfect 5.0-star rating across 95 Google reviews is unusual for a restoration company. Many of those reviews come from Local Guides and repeat reviewers with substantial review histories, which makes the rating harder to dismiss as inflated.
Services
Service area
Cornerstone operates from Lombard, IL, and serves the western and northwestern Chicago suburbs. Their website lists 40+ cities including Aurora, Naperville, Wheaton, Elmhurst, Schaumburg, St. Charles, Geneva, Batavia, Downers Grove, Glen Ellyn, Hinsdale, Oak Brook, Barrington, Palatine, and DeKalb. That range stretches roughly 50 miles from their Lombard office, so response times at the outer edges may vary.
Review consensus
Brandon Silva draws the most mentions across reviews. Reviewers describe him as knowledgeable, responsive, and willing to build custom proposals (Ela Danowska). Jason McReynolds gets praised for honesty, particularly for telling homeowners they do not have a mold problem when that is the case (Charlie Klemm, Sandra Semler). Crew members Ricky, Rob, Leo, Jacob, and Al get named repeatedly for hard work and respectfulness. Multiple reviewers highlight insurance claims assistance, with Jennifer Berg noting that documentation made it easy to work with her insurance company. Elise Harczos and others mention that the team walks homeowners through claim details. Repeat customers like Jacqueline Smith (four events over several years) and John Brandau (years of use) signal long-term reliability.
0 found across 95 total reviews at 5.0★. No 1-star reviews found. Zero negative reviews (3 stars or below) appeared in the last 18 months across 95 total reviews at 5.0 stars.
The unusually high review volume with a perfect rating correlates with a pattern visible in the reviews: owner Jason McReynolds and manager Brandon Silva stay personally involved in nearly every project. Reviewers consistently describe direct contact with one or both of them, not just field crews. This owner-present model likely drives both the service quality and the review rate, since customers feel a personal connection worth writing about.
Brandon Silva (operations manager — praised consistently for responsiveness, knowledge, and guiding homeowners through insurance and remediation). Jason McReynolds (owner — praised for honesty, prompt assessments, and telling customers when they do not need services). Ricky (field crew — praised for hard work and attention to detail). Rob/Robert (field crew — praised for quality cleanup work). Leo (field crew — praised for hard work on basement restorations). Jacob (field crew — praised for mold remediation and cleaning work). Al/Alex (field crew — praised for long hours and thorough work). Danny (field crew — praised for basement flood cleanup). Luke (field crew — praised alongside Jacob and Brandon). Jose (field crew — praised for outstanding work). Pancho (field crew — praised for quality work). Louie (field crew — praised for kitchen and basement cleanup).
Ask for Brandon or Jason when you call. Every review that names staff points to one of them as the primary contact, and the consistency suggests this is not accidental. With zero complaints in 18 months, the main risk is whether their wide service area means longer response times if you are far from Lombard.
Keep in mind
- Cornerstone does both mold testing (free assessments) and mold remediation. That means the company evaluating whether you have a mold problem is the same one that profits from fixing it. They do refer to an independent environmental hygienist for air and surface testing, which partially offsets this, but you should still consider getting an independent inspection before signing a remediation contract.
- Their service area lists 40+ cities spanning from DeKalb to Palatine to Woodridge. That covers a large geographic footprint from a single Lombard office. Ask about response times for locations on the edges of that range.
- The website uses heavy SEO templating, with nearly identical mold remediation pages for each city they serve. The actual service capabilities are the same regardless of which city page you land on.
- With zero negative reviews in the last 18 months, there is no recent complaint data to evaluate. A perfect record is reassuring but also means you cannot benchmark what goes wrong when it does.
