Damage Restoration in Hollis, NY
Mold remediation in Hollis is shaped by the neighborhood’s dense blocks of 1920s-1940s brick semi-detached homes, where plaster walls absorb moisture for weeks and shared party walls let mold travel between units before anyone sees it. Most jobs we handle in Hollis start as a basement water event, then turn into a multi-room mold issue because the original lath-and-plaster never fully dried. If you’re seeing stains or smelling must in a Hollis row house, call (629) 213-4606 for a written assessment.
Why Hollis Homes Are Different
Hollis is built almost entirely on dense blocks of 1920s-1940s semi-detached and attached brick homes. That means water damage, fire char, and mold routinely migrate through shared party walls into neighboring units. A sewage backup in one basement often damages two or three legally distinct properties through one connected structure. The homes themselves feature original lath-and-plaster interior walls and old-growth lumber framing, materials that absorb and retain moisture far longer than modern drywall. Plaster complicates moisture readings and extends drying times significantly during any restoration job.
Southeastern Queens sits on a low-lying coastal plain with limited natural drainage gradients. During nor’easters and intense summer convective storms, the area’s combined sewer system regularly surcharges and backs up into basements across Hollis. Many Hollis basements were finished informally over decades, often without permits, which creates insurer and code-compliance issues that a Queens-savvy restorer must navigate before rebuild begins. The freeze-thaw cycle common to NYC winters also stresses brick masonry on these older homes, creating recurring mortar failure and water infiltration points that feed interior mold between major storm events.
Our Main Hollis Services
Hollis homeowners call most often about two things: water damage that won’t dry, and storm-driven sewer backups that flood finished basements. Both of these pages have their own dedicated Hollis resource.
Water Damage Restoration in Hollis
Water in a Hollis row house doesn’t stay in one unit. Plaster walls wick moisture horizontally, and the shared party-wall construction means a leak on one side becomes damp on the other within days. Our crews run Injectidry and Dri-Eaz drying systems with daily moisture logs, documenting every reading so your insurer sees exactly what was found and what was done. See the full breakdown on our Water Damage Restoration in Hollis page, including written pricing before work starts.

Storm & Disaster Restoration in Hollis
When southeastern Queens’s combined sewer system surcharges during a nor’easter, Hollis basements back up fast. The neighborhood’s aging brick homes take on groundwater through mortar joints and foundation cracks, and the post-Superstorm Sandy era exposed just how vulnerable this infrastructure is to prolonged inundation. Our storm response includes board-up, water extraction, structural drying, and full documentation. Read the complete scope and pricing on our Storm & Disaster Restoration in Hollis page.

Before
AfterMold Remediation in Hollis


Mold in Hollis homes is rarely a surface problem. The 1920s-1950s brick row houses and semi-detached homes were built with plaster walls that hold moisture for weeks after a leak or basement flood, and shared party walls mean mold colonies in one unit feed into the next through hidden stud cavities. Because so many Hollis basements were finished informally over decades without vapor barriers or proper drainage, mold grows behind finished walls and under flooring long before it becomes visible. Our Mold Remediation process starts with moisture readings and a written scope, then removes the colony and corrects the moisture source so it doesn’t return.
Mold Inspection & Testing
Signs you need it
Visible staining on plaster walls, a persistent musty smell in a finished Hollis basement, or peeling paint above baseboards after any water event.
What it costs in Hollis
Mold inspection and air quality testing in Hollis typically runs $350-$650, with the written report included.
How we do it
We run room-by-room moisture readings, collect air and surface samples, and deliver a written lab report with a remediation scope in plain language.
Mold Removal
Signs you need it
Confirmed mold growth behind finished basement walls, on ceiling joists after a sewer backup, or spreading across plaster after prolonged dampness.
What it costs in Hollis
Mold removal in Hollis averages $1,200-$3,400 depending on affected square footage and whether party-wall containment is required.
How we do it
We build containment, scrub the air with HEPA filtration, remove affected plaster or drywall, treat framing with antimicrobials, and document every step.
What Mold Remediation Costs in Hollis
| Item | Typical range in Hollis |
|---|---|
| Mold Inspection & Testing | $350-$650 |
| Mold Removal (single room) | $1,200-$2,200 |
| Mold Removal (whole basement) | $2,800-$3,400 |
Will my homeowner’s insurance cover mold remediation in Hollis?
Coverage depends on the source of the water that caused the mold. Sudden, accidental water events like a burst pipe are often covered; long-standing moisture or flooding is often excluded. Our photo record and moisture logs give your adjuster exactly what they need to evaluate the claim accurately.
How fast can you get mold out of a Hollis row house?
We can dispatch a crew to Hollis within hours for an assessment, and remediation often starts the same day once the written scope is approved. Call (629) 213-4606 for a free written estimate.
Fire & Smoke Damage Restoration in Hollis


Fire in a Hollis attached brick home rarely stays contained to one unit. Smoke travels through shared roof cavities, party-wall gaps, and old electrical chases, leaving odor and soot in neighboring properties even when flames never crossed the wall. The original lath-and-plaster in these 1920s-1950s homes absorbs smoke deeply, and the old-growth lumber framing holds char odor long after visible soot is wiped clean. Our Fire & Smoke Damage Restoration process includes structural cleaning, odor neutralization, and written documentation for every affected room.
Smoke & Soot Removal
Signs you need it
Dark residue on walls and ceilings, a lingering smoke smell days after a fire, or soot staining around door frames and electrical outlets.
What it costs in Hollis
Smoke and soot removal in Hollis typically runs $1,500-$4,200 depending on affected square footage and plaster porosity.
How we do it
We dry-sponge plaster surfaces, HEPA-vacuum all cavities, and use specialized cleaning agents rated for pre-1950s building materials.
Odor Removal & Deodorization
Signs you need it
A smoke odor that persists in a Hollis home after surfaces look clean, particularly in closed-up rooms or finished basements.
What it costs in Hollis
Ozone and thermal fogging odor removal in Hollis averages $800-$1,800 for a single attached unit.
How we do it
We deploy hydroxyl generators and thermal fogging, then document air quality readings before and after treatment.
What Fire & Smoke Damage Restoration Costs in Hollis
| Item | Typical range in Hollis |
|---|---|
| Smoke & Soot Removal (per room) | $400-$700 |
| Odor Removal & Deodorization | $800-$1,800 |
| Full Fire Cleanup (attached unit) | $3,500-$6,000 |
Will my insurance cover fire restoration in a Hollis attached home?
Fire is typically a covered peril, but the shared-wall nature of Hollis row houses means your neighbor’s insurer may also be involved. Our written scope and photo record make the division of responsibility clear for both adjusters.
How fast can you board up a Hollis home after a fire?
Emergency board-up is dispatched within hours to Hollis, 24/7. Call (629) 213-4606 and a live person answers, no voicemail tree.
Sewage Cleanup in Hollis


Sewage backups in Hollis are a recurring condition, not a one-time accident. The neighborhood’s 1920s-1950s attached homes share aging combined sewer lines with the broader southeastern Queens drainage system, and during heavy rain those lines surcharge and push black water back through basement floor drains. Because so many Hollis basements were finished informally over decades, a backup that starts in one unit often contaminates finished living space, carpet, and drywall across multiple properties through shared party walls. Our Sewage Cleanup process includes extraction, sanitization, and moisture readings documented to IICRC standards.
Sewage Backup Cleanup
Signs you need it
Black water pooling around a Hollis basement floor drain, sewage smell after heavy rain, or water backing up in a finished basement toilet or tub.
What it costs in Hollis
Sewage backup cleanup in Hollis typically runs $1,800-$4,500 for a finished basement with carpet and drywall removal.
How we do it
We extract black water, remove contaminated materials, sanitize with EPA-registered antimicrobials, and run drying equipment with daily logs.
Sanitization & Disinfection
Signs you need it
Any surface a Hollis sewage backup touched, including concrete floors, wall framing, and any furnishings that were not removed.
What it costs in Hollis
Standalone sanitization and disinfection in Hollis averages $500-$1,200 depending on affected square footage.
How we do it
We apply hospital-grade disinfectants, fog enclosed cavities, and provide a written sanitation log for your insurer.
What Sewage Cleanup Costs in Hollis
| Item | Typical range in Hollis |
|---|---|
| Sewage Backup Cleanup (basement) | $1,800-$4,500 |
| Black Water Extraction (per room) | $400-$750 |
| Sanitization & Disinfection | $500-$1,200 |
Is sewage backup covered by insurance in Hollis?
Standard homeowner’s policies often exclude sewage backup unless a specific endorsement was purchased. Some Hollis homeowners carry coverage through their lender or a rider. Our written scope and photo record give your adjuster exactly what they need to determine coverage under your policy.
How fast can you respond to a Hollis sewage backup?
We answer live 24/7 and can have a crew in Hollis within hours. A fast response prevents contamination from spreading through shared party walls into neighboring units. Call (629) 213-4606 now.
Biohazard & Crime Scene Cleanup in Hollis


Biohazard cleanup in Hollis requires care that goes beyond the technical work. The neighborhood’s attached brick homes mean a biohazard event in one unit can affect shared spaces, entryways, and even neighboring properties, and the original plaster walls in these pre-1950s buildings absorb biological fluids in ways modern drywall does not. Our Biohazard & Crime Scene Cleanup teams are trained in discrete, documented remediation that restores the space safely and respectfully.
Trauma & Unattended Death Cleanup
Signs you need it
Any situation where biological fluids or decomposition have affected flooring, walls, or furnishings in a Hollis home or shared building.
What it costs in Hollis
Trauma cleanup in Hollis typically runs $2,500-$6,000 depending on affected area and materials requiring removal.
How we do it
We remove affected materials, sanitize treated framing and plaster, and run air scrubbing with HEPA filtration until readings are clean.
Hoarding Cleanup
Signs you need it
A Hollis home where accumulated contents prevent safe access to plumbing, electrical, or structural systems and create a health hazard.
What it costs in Hollis
Hoarding cleanup in Hollis averages $3,000-$8,000 for a full attached unit, including debris removal and sanitization.
How we do it
We clear contents with a documented inventory, remove contaminated materials, and sanitize all surfaces to safe living standards.
What Biohazard & Crime Scene Cleanup Costs in Hollis
| Item | Typical range in Hollis |
|---|---|
| Trauma & Unattended Death Cleanup | $2,500-$6,000 |
| Blood & Bodily Fluid Cleanup | $1,500-$4,000 |
| Hoarding Cleanup (full unit) | $3,000-$8,000 |
Will insurance cover biohazard cleanup in Hollis?
Many homeowner’s policies include coverage for biohazard remediation when it results from a covered event, such as an accident on the property. Our documented photo record and itemized scope make the claim process straightforward for you and your adjuster.
Who coordinates with my adjuster on a biohazard claim?
Our team handles direct adjuster coordination with photo documentation and written scopes. We work with your insurer the same way we work with you: everything in writing, nothing verbal. Call (629) 213-4606 to start.
Reconstruction & Cleanup in Hollis


Reconstruction in a 1920s-1950s Hollis brick home means working with old-growth lumber framing, original plaster walls, and spaces that were often finished informally over decades without permits. Bring a rebuild back to code here requires a Queens-savvy team that understands what the Department of Buildings will flag on a prewar attached structure. Our Reconstruction & Cleanup team writes a fixed scope before any work begins, so you know exactly what the rebuild costs and what it includes.
Drywall & Flooring Repair
Signs you need it
Water-damaged plaster or flooring in a Hollis home that has been dried but not rebuilt, with visible sagging, staining, or warping.
What it costs in Hollis
Drywall and flooring repair in Hollis typically runs $2,500-$6,000 per room depending on material matching and plaster restoration.
How we do it
We match prewar plaster profiles when possible, install new subfloor where needed, and document every replacement with photos.
Post-Construction Cleanup
Signs you need it
A Hollis home that has just completed renovation or rebuild work, with construction dust, debris, or residue on every surface.
What it costs in Hollis
Post-construction cleanup in Hollis averages $800-$2,000 for a full attached unit, including HEPA air scrubbing.
How we do it
We HEPA-vac all surfaces, clean plaster dust from ductwork and cavities, and deliver a written cleanliness verification.
What Reconstruction & Cleanup Costs in Hollis
| Item | Typical range in Hollis |
|---|---|
| Drywall & Flooring Repair (per room) | $2,500-$6,000 |
| Full-Service Reconstruction (basement) | $12,000-$28,000 |
| Post-Construction Cleanup | $800-$2,000 |
Do I need a permit for reconstruction work in Hollis?
Most structural rebuild work in Hollis requires a DOB permit, particularly when finished basement space was added informally. We document the permit status in our written scope before work starts, so there are no surprises mid-project.
How is reconstruction pricing different from emergency restoration pricing?
Reconstruction is scoped, scheduled, and priced in writing like a remodel, not dispatched same-day like mitigation work. You receive a fixed written price before any rebuild begins. Call (629) 213-4606 to schedule a Hollis assessment.

FAQs About Damage Restoration in Hollis
Our live dispatch is available 24 hours a day, 7 days a week, and we typically have a crew in Hollis within one to two hours for water, sewage, or fire emergencies. Mold assessments are usually scheduled within one business day. Call (629) 213-4606 and a person answers.
Mitigation work like drying, mold removal, and sewage cleanup generally does not require a DOB permit. Reconstruction and structural rebuilds often do, particularly when finished basement space was added informally. We document permit requirements in our written scope before any rebuild work begins.
When water, smoke, or sewage crosses a shared party wall, both properties may need restoration. We document each unit separately with its own photo record and scope, which makes it clear to both insurers which work belongs to which claim. That’s the documentation-first standard we’ve run since Alicia Brennan founded the company in 2011.
