Fast, Reliable Water Damage Restoration Across Hollis
Water damage in Hollis moves through brick party walls, not just across floors. A sewer backup at one address routinely becomes a two- or three-property loss before anyone opens the basement door. We respond to Hollis homes within hours, not days, because the difference between extracting now and extracting tomorrow is whether your lath-and-plaster walls stay or get cut out. Call (629) 213-4606 and a live person answers. Not a voicemail tree. Not a callback queue. A person who knows what a 1930s semi-detached row house looks like from the inside.
Why DryMark Restoration Is Hollis’s Preferred Water Damage Restoration Company
Alicia Brennan built DryMark Restoration in 2011 around a documentation gap she saw repeatedly as a claims adjuster: homeowners lost money because nobody wrote down what was wet, how wet it was, and what it cost to dry it. So we built the company backward from that failure. Every Hollis job starts with a written price before any work begins. That is Haven Standard, Clause 1: a signed quote on paper, not a verbal range. Every visit includes a photo record. Every drying decision is logged with moisture readings, room by room, day by day. If your insurer questions a charge, the answer is already on file.
Our Water Damage Restoration team works in Hollis weekly. We know that homes off 104th Avenue, Jamaica Avenue, and Francis Lewis Boulevard sit on a low-lying coastal plain where combined sewers surcharge during summer storms. We know that original lath-and-plaster walls read “dry” on the surface while holding 30% moisture in the core. We know that one broken pipe in a semi-detached brick home means checking the neighbor’s basement before calling the extraction done. That is not general restoration experience. That is Hollis-specific experience.
Our Water Damage Restoration Services in Hollis

Emergency Water Extraction
When a sewer line backs up into a Hollis basement, water does two things at once: it saturates whatever it touches, and it starts migrating through the party wall. Our crews arrive with truck-mounted extraction units and submersible pumps rated for category 3 water. We pull standing water first, then pressure-test the shared wall to confirm whether it wicked through. In a 1938 semi-detached off 104th Avenue, we found the neighbor’s finished basement holding an inch of contaminated water before the owner even knew. Containment went up at the party wall that same hour.

Structural Drying & Dehumidification
Drying a Hollis row house is not the same as drying a drywall-and-stud colonial. Plaster from the 1920s and 1930s holds moisture long after the surface feels dry. We run Dri-Eaz LGR 7000XLi dehumidifiers and XPOWER air movers in a calculated layout, then use penetrating moisture meters to read what is happening inside the plaster core, not just on its face. Daily drying logs show vapor pressure differential and moisture content percentages, documented to IICRC standards. You get those logs. So does your adjuster. A wall is not “dry” until the numbers say it is dry.

Flood Cleanup
Hollis sits where the southeastern Queens drainage system flattens out. When the combined sewer surcharges during a nor’easter or an intense summer storm, it backs into the lowest point of every connected building: the basement. That water often carries sewage and whatever the street drains collected. Flood cleanup in Hollis means treating every affected surface as a potential biological hazard, flushing and disinfecting concrete and masonry, and verifying that water did not cross into the attached unit. We do not dry a flooded basement and call it done. We map where the water went and prove it.

Burst Pipe Restoration
Hollis winters hit brick masonry with a freeze-thaw cycle that works joints and mortar loose over decades. When a supply line bursts behind an original plaster wall, the damage spreads behind the surface before you see a stain. We trace the piping, isolate the break, remove saturated plaster and insulation to clean edges, and dry the framing underneath. Old-growth lumber framing from the 1930s is dense; it dries slower than modern softwood, and we account for that in the extraction plan and the drying schedule.

AfterTrusted Brands We Service in Hollis
Our crews work with professional-grade drying systems from Dri-Eaz, XPOWER, B-Air, and Injectidry, and we stock the common parts and drying accessories needed for Hollis homes. Everything is documented to IICRC and RIA standards, with IFA-compliant drying logs where applicable. If a dehumidifier fails at 2 a.m., we swap it out, not leave the job stalled until morning. That kind of uptime matters when the plaster core is still at 28% moisture and your adjuster is asking why the equipment was down for nine hours.
Common Water Damage Restoration Problems We See in Hollis Homes

- Water moving through shared party walls. Semi-detached and row-style brick homes share more than a wall. They share drainage, mortar joints, and in many cases, basement subfloor framing. A sewer backup in one unit is a live mold risk in the attached unit, even when that unit’s basement looks dry. We contain at the partition regardless of what the initial inspection shows.
- Lath-and-plaster walls that lie to a surface meter. A standard moisture probe pressed against painted plaster reads the paint, not the wall. The plaster core can hold 35% moisture while the surface reads 9%. In Hollis’s 1920s-1940s housing stock, we rely on penetrating meters and reference probes to get real numbers, because drywall assumptions fail on these walls.
- Unpermitted finished basements colliding with insurance claims. Generations of Hollis homeowners converted basement spaces to finished living areas without Department of Buildings permits. When water destroys that space, the insurer may deny coverage for the finish work. We identify the permit status early and document the original construction so the owner can argue the claim with evidence, not hope.
- Recurring basement flooding from combined sewer surcharge. A single extraction does not fix the underlying problem when the city system backs up every heavy storm. Hollis basements need restoration scopes that include drainage assessments, backwater valve considerations, and moisture management recommendations, not just a drying cycle. The water returns. The plan should not.
Pricing for Water Damage Restoration in Hollis, NY
A typical emergency water extraction in Hollis runs $1,200-$3,800, depending on the affected square footage and the water category. Structural drying and dehumidification generally costs $800-$2,500, with longer runs on original plaster walls. A basement water removal with contamination runs $2,000-$6,500 once antimicrobial treatment, debris removal, and containment are factored in. A burst pipe restoration with plaster cutout and framing repair typically lands between $1,800-$5,400. These ranges account for semi-detached layouts where the job may extend into the attached unit.

FAQs - Water Damage Restoration in Hollis

We treat the structure as a connected system, not as two separate addresses. We contain at the party wall, run moisture mapping on both units, and coordinate access with the attached owner even if their side looks untouched. Water wicks through brick and shared framing. A dry-looking neighbor basement can still be holding contaminated moisture behind their finished wall. Our containment and drying plan covers both properties so you are not filing a second claim in three weeks. Call (629) 213-4606 and we will walk the shared wall with you.
Your basement is the lowest point on a combined sewer system that surcharges when stormwater exceeds capacity. The pipes that carry sewage and rainwater are the same pipes, and in southeastern Queens, they back up into basements during intense convective storms. Restoration stops the immediate damage: we extract, treat, dry, and document. But we also identify what keeps recurring, whether that means a backwater valve recommendation, a drainage check, or a grading issue at the exterior. You need both: the emergency response and the durable correction. Call (629) 213-4606 for a written assessment.
It depends on the moisture content at the plaster core and how long the wall has been wet. Plaster walls from the 1920s and 1930s can often be saved if the water source is cut quickly and the drying plan uses penetrating meters, not surface probes. But category 3 water that has soaked the plaster for more than 48 hours usually means cutting out the lower three feet and replacing it with drywall or new plaster. We give you numbers, not a guess. If the core reads under 18% and has not delaminated from the lath, we dry it. If it is above 30% and crumbling, we cut it. The answer comes from the meter, not from a sales conversation.
It can be. Insurers routinely deny coverage for finish work in basements that lack a Department of Buildings permit, especially in Hollis where informally converted basements are common. The denial gets messier when the damage claim includes that finished space. What helps: a restoration company that documents the original construction, identifies which surfaces are pre-existing and unpermitted, and produces a drying log your adjuster can use to separate the covered mitigation from the non-covered finish work. That documentation makes a difference in what ultimately gets paid. We flag the permit question before drying starts, not after the claim is filed.
Mold can start within 24 to 48 hours under the right conditions, and those conditions are common in Hollis basements: warm, humid air, organic material in plaster and old wood framing, and standing water from a sewer backup or supply line break. The source matters significantly. Clean water from a supply line gives you a slightly longer window before microbial growth becomes aggressive. Sewage or stormwater carrying organic matter shortens that window and raises the health risk. In a shared party-wall structure, mold that starts on one side can move through wall cavities into the attached unit. Call (629) 213-4606 the day you see water, not the day after.
