Provider snapshot
What this listing says
Hanover-area homeowners dealing with water damage that has led to mold, where having one crew handle extraction, drying, and remediation under the same roof saves days of coordination.
Best for
- Homeowners in south-central Pennsylvania or central Maryland who need water damage and mold handled by the same crew without subcontracting.
- Emergency situations where you need someone on-site within 90 minutes, day or night, with a live person answering the phone.
- Insurance-claim situations where you want a company that will help you file and coordinate with your carrier from the start.
- Post-flood mold concerns where the water source needs to be traced and dried before remediation can begin.
About this company
Mason-Dixon Restoration is a locally owned restoration company based in Hanover, Pennsylvania, with a second office in Ellicott City, Maryland. They handle water damage, fire damage, and mold remediation across both states, which means they can take a water emergency from extraction through mold cleanup without handing you off to a second contractor.
Their mold work follows a documented process: inspection and testing, containment with plastic sheeting, HEPA air filtration, removal with antimicrobial treatment, and moisture source repair using thermal imaging and moisture meters. They also offer art restoration, which is unusual for a restoration company. The website claims IICRC firm-level certification and a 90-minute on-site response window around the clock.
Founders Wes and Justin bring over 24 years of combined experience in restoration and have worked together for more than 10 years. The company runs a sizable field crew — reviews routinely name 15+ different technicians — and staffs a live answering line 24/7. They operate across Adams and York counties in Pennsylvania and Prince George's, Anne Arundel, Montgomery, Howard, Baltimore, Frederick, Carroll, and Harford counties in Maryland.
A 5.0-star rating across 308 Google reviews is statistically rare for a restoration company with this volume. Only 2 reviews in the last 18 months fall at 3 stars or below, and neither contains a detailed complaint. That track record is worth noting, though the company is still relatively young.
Services
Service area
Headquartered in Hanover, Pennsylvania, with a second office in Ellicott City, Maryland. They list service coverage across Adams and York counties in PA and Prince George's, Anne Arundel, Montgomery, Howard, Baltimore, Frederick, Carroll, and Harford counties in MD. That is a wide geographic spread across two states — confirm response times for locations far from either office.
Review consensus
Brandon, Jimmy, and Dan appear most often across reviews and draw consistent praise for clear explanations, same-day arrivals, and keeping homeowners informed throughout multi-day jobs. Ethan, Adam, Chase, Zach, Don Weller, and Dan Linga are also named repeatedly. Reviewers consistently highlight two things: the crew explains every step before doing it, and they coordinate directly with insurance companies and other contractors (plumbers, HVAC) so the homeowner does not have to manage multiple vendors. Several reviewers note the team moved furniture carefully and cleaned up thoroughly after extraction work.
2 found across 308 total reviews at 5.0★. Almost nothing. The single 1-star review from Samantha Vega says only "he lied to us" with no specifics. The owner responded immediately, stating they have no record of working with or speaking to this person and inviting her to call. The 3-star from Susan Steele has no text at all. Neither complaint provides enough detail to identify a pattern or even a specific failure.
The near-absence of complaints is the pattern. With 308 reviews and a perfect 5.0, this company either delivers remarkably consistent service or actively manages its review profile. The owner responds to both negative reviews — one with a specific factual rebuttal (no customer record found), one with a brief thank-you. The 1-star reviewer has only 2 total Google reviews and zero likes, which weakens but does not invalidate the complaint. Worth noting that the vast majority of positive reviews name specific crew members and describe specific situations, which is a strong authenticity signal.
Brandon (technician/project overseer — consistently praised). Brandon Warner (technician — praised for humor and thoroughness). Brandon West (crew lead — praised). Jimmy (technician — praised across many reviews for communication and thoroughness). Dan Linga (project manager — praised for same-day assessments and insurance help). Don Weller (manager/technician — praised for leadership and responsiveness). Ethan (technician — praised for promptness and flexibility). Adam (technician — praised for care and efficiency). Chase (technician — praised for empathy and professionalism). Zach (technician — praised for communication). Jayden/Jadon (technician — praised). Sam (technician — praised). Tyler (technician — praised for respectfulness). Shane (technician — praised). Eric (technician — praised). Jason (technician — praised). Jamie (technician — praised for reducing stress). Sophie (administrative — praised for kindness). Stanley (technician — praised for thoroughness).
With 308 reviews at a perfect 5.0 and essentially zero substantive complaints, Mason-Dixon's track record is unusually strong. Ask for Brandon, Jimmy, or Dan by name — they appear most often in reviews. Since they do both testing and remediation, get a second opinion on the mold test results before signing a remediation contract.
Keep in mind
- Mason-Dixon does both mold testing and mold remediation. That means the same company diagnosing your mold problem also profits from fixing it. Consider getting an independent mold test before committing to their remediation scope.
- Their service area spans two states and ten-plus counties. If you are on the outer edges — say, Prince George's County or Harford County — confirm actual response times for your location before assuming the 90-minute window applies.
- The website still has placeholder text (lorem ipsum) on several service pages, which suggests the site is newer and some service descriptions may not reflect their actual capabilities in detail.
- Most reviews reference water damage work. Mold-specific reviews are fewer, so the stellar rating reflects the full service mix rather than mold remediation alone.
