Fast, Reliable Storm & Disaster Restoration Across Hollis
Storm damage in Hollis doesn’t look like it does in other Queens neighborhoods. The 1920s and 1930s brick rowhouses that line 191st Street, 104th Avenue, and the blocks around Hollis Avenue share party walls, original lath-and-plaster interiors, and basements that were finished decades ago without permits. When a nor’easter pushes sewage up through the combined drains, water moves through those shared walls into neighboring homes. DryMark Restoration responds to Hollis within 60 to 90 minutes on storm emergencies, seven days a week. Call (629) 213-4606 and a live person answers, no voicemail tree.
Why DryMark Restoration Is Hollis’s Preferred Storm & Disaster Restoration Company
Our crews know that a flooded basement on 191st Street is rarely contained to one address. In Hollis, we routinely find that a single sewer backup has saturated two or three connected basements through one party wall. That’s why our scopes are written room by room, with moisture readings taken from both sides of shared masonry before we declare anything dry.
We document everything: daily drying logs from Dri-Eaz and XPOWER equipment, photo records on every visit, and a written price before any work starts. That’s Haven Standard, Clause 1, and it’s not a marketing line. Alicia Brennan founded DryMark after working as a claims adjuster and watching homeowners lose coverage because their restoration contractor couldn’t produce evidence. We produce evidence.
Local knowledge is the difference here. Plaster walls in Hollis homes hold moisture far longer than drywall, and techs who rely on surface readings miss what’s trapped behind baseboards. We don’t. Our meters go into the wall cavities, and we log readings every twelve hours until the numbers flatten under IICRC standards.
Our Storm & Disaster Restoration Services in Hollis

Flood Damage Restoration
Basement flooding in Hollis is a chronic condition, not a one-off event. The combined sewer system that serves southeastern Queens surcharges during heavy rain, and water backs up through floor drains across 11423, 11412, and surrounding ZIP codes. We extract the water, cut back saturated lath-and-plaster where needed, run Dri-Eaz dehumidifiers and B-Air air movers on 12-hour logging cycles, and install permanent backwater valves so the same backup doesn’t return in six weeks.

Storm Damage Cleanup
Wind-driven rain pushes water through failing mortar joints in Hollis’s old brick facades, and the freeze-thaw cycle widens those cracks every winter. The result is interior water damage that starts small and feeds mold behind plaster walls. Our crews trace the intrusion points, repair the masonry where needed, and treat the affected cavities with antimicrobials before rebuilding. If you see brown staining on a party wall in a semi-detached home near Hillside Avenue, don’t wait for it to spread through the wall to your neighbor’s side.

Emergency Board-Up
When a tree limb or flying debris takes out a window on a Hollis rowhouse, the opening exposes both your unit and the attached neighbor’s structure to weather and unauthorized entry. We board up within hours, using exterior-grade plywood anchored to the masonry openings, and we photograph every step. The photo record goes to your insurer with the scope of work, so the claim doesn’t stall on documentation gaps.

Roof Tarping
Flat and low-slope roofs on 1920s brick homes fail at the parapet walls and scuppers first. A torn section of roll roofing over a Hollis rowhouse sends water down the party wall cavity, where it hits lath-and-plaster and old-growth framing. We tarp with heavy-duty reinforced poly, anchored against wind uplift, and scope the permanent repair in writing before any rebuild starts.

Common Storm & Disaster Restoration Problems We See in Hollis Homes

- Category 3 water behind false walls: Unpermitted basement conversions in Hollis often hide plumbing and electrical behind drywall that covers original plaster. When sewer water reaches that space, it contaminates insulation and wiring that no standard scope accounts for. We cut back two feet, inspect what’s hidden, and rebuild to code before anything gets closed up.
- Mold blooming after “complete” drying: Plaster walls in semi-detached Hollis homes wick moisture deep into the masonry. Surface readings look dry while the cavity behind the baseboard is still at 40% moisture content. We use penetrating meters and in-wall drying systems, and we don’t sign off until the cavity numbers drop and hold.
- Re-flooding weeks after extraction: Contractors who only pump out water and run fans leave the backwater valve unaddressed. The next heavy rain surcharges the same combined sewer on 191st Street, and the basement floods again. Our scopes always include permanent backflow prevention when the source is sewer surcharge.
- Party-wall coordination failures: A flood on one side of a shared wall always pulls moisture into the neighbor’s side. If both owners don’t coordinate drying, mold grows in the wall and both properties end up with a bigger problem. We handle the communication, the access, and the joint documentation.

FAQs - Storm & Disaster Restoration in Hollis

Because Hollis sits on a combined sewer system that mixes stormwater with raw sewage, so when the system surcharges during a nor’easter, what backs up into your basement isn’t rainwater, it’s contaminated water carrying sewage, bacteria, and whatever the drain system picked up along the way. That’s Category 3 by definition, which means full antimicrobial treatment, not just drying. Skipping that step leaves a biohazard in your lath-and-plaster walls. Call (629) 213-4606 for a written scope that treats it correctly.
We access both sides of the wall before we do anything else. A shared brick party wall saturated from one side will wick water into the neighbor’s cavity, so we get permission from both owners and document both units in one scope. Then we set extraction and drying equipment on both sides and run penetrating moisture meters into the wall cavity every twelve hours. If you wait until the mold shows on your side, the neighbor’s side is already compromised. Call us at the first sign of water on the shared wall.
We document what’s there, cut back the saturated drywall and insulation as needed, treat the cavity, and rebuild the affected area to current code, including proper egress where required. We won’t pretend the unpermitted work doesn’t exist, because your insurer will find out anyway. What we do is handle the code issues during restoration so you’re not fighting the Department of Buildings later. Call (629) 213-4606 and ask for Alicia Brennan’s team if you’re dealing with this scenario.
Mold spores germinate on saturated lath-and-plaster in 48 to 72 hours in Hollis’s humid summer conditions, but the deeper problem is the moisture trapped inside the wall cavity, which can support mold growth behind baseboards for weeks after the surface looks dry. That’s why our drying logs run for ten to fourteen days on plaster construction, not the three to five days a drywall job takes. The readings tell us when it’s actually dry, not the calendar.
Because the contractor extracted water and ran fans but never installed a backwater valve or addressed the combined sewer surcharge that caused the flood in the first place. In Hollis, the next heavy rain comes and the same drain backs up again. We include permanent backflow prevention in every sewer-related flood scope, and we waterproof the exterior or the interior depending on what the masonry shows. If your basement flooded twice in one season, call (629) 213-4606 and we’ll show you what was missed the first time.
