Targeted Building Envelope Protection
Waterproofing (roof, foundation, facade)
We deliver code-compliant waterproofing for roofs, foundations, and façades to protect occupied buildings and capital projects.
As a licensed waterproofing contractor, we serve Huntington Station and New York City, all five boroughs, Long Island, and the Tri-State region. For larger jobs we travel up to 100 km; for smaller work we prefer within 50 km, and we welcome inquiries outside these ranges from building owners.
Compliance-Driven Waterproofing You Can Trust
Experienced, Licensed, Fully Insured
We approach roof, foundation, and façade waterproofing as a compliance-first discipline that protects structures, interiors, and budgets.
Working across Huntington Station and New York City—and throughout all five boroughs, Long Island, and the Tri-State—we deliver code-aligned scopes planned by our in-house team with engineering support and required special inspections.
On roofs, we restore and replace EPDM, modified bitumen, and coating systems, integrating terminations and details to manufacturer requirements. Below grade, we install positive- and negative-side assemblies to control hydrostatic pressure and seepage at walls, slabs, and planters.
On façades, we perform selective repointing and install high-performance sealants at window perimeters and control joints, using silicone, urethane, or STP chemistries from proven brands such as Sika and Pecora.
Our vertical access capabilities include suspended scaffolding, pipe scaffolding, sidewalk sheds, and access elevators to safely reach occupied elevations while maintaining pedestrian protection. We handle NYC DOB/DOT permits and after-hours authorizations, maintain OSHA programs, and operate under umbrella insurance to protect every project.
We coordinate third-party asbestos/environmental investigations when required. For transparency, we do not coordinate penetrations and flashings with other trades, and while we have landmark experience, we do not manage LPC/SHPO approvals.
Clients choose us for clear documentation, responsive 24/7 emergency leak response, and disciplined execution that aligns waterproofing with façade restoration and exterior building restoration objectives—delivering durable assemblies, compliant closeout, and reliable performance.
Waterproofing Questions We’re Asked Daily
Which foundation waterproofing methods suit my building?
We evaluate water sources, hydrostatic pressure, and substrate condition, then design assemblies using positive- or negative-side barriers, drainage composites, and compatible primers. As a waterproofing contractor, we install systems that meet code and manufacturer requirements for longevity and maintainability across Huntington Station and New York City, with special inspections when required to document performance and compliance.
When is roof restoration vs replacement smarter?
We assess aging, trapped moisture, and detailing. If insulation, membrane, and terminations are sound, targeted restoration with coatings may extend service life; when saturation, blistering, or failed seams are widespread, replacement is more reliable. Our roof waterproofing details align with manufacturer standards so owners in Huntington Station and New York City receive durable, documented outcomes.
What affects façade restoration and waterproofing cost?
Variables include substrate type, access constraints, required permits, quantity of repointing, and sealant lineal footage. We provide clear scopes so façade restoration integrates with waterproofing without scope creep. Because every building is different, we price after site review and drawings—not online calculators—to protect budgets and compliance for exterior building restoration projects.
How often should sealants be replaced?
Service life varies by chemistry, UV exposure, movement, and workmanship. We typically see 10–20 years, but perimeter joints under movement or ponding fail sooner. During façade waterproofing, we match silicone, urethane, or STP products to conditions and backer-rod geometry, referencing brands like Sika and Pecora to maintain watertight continuity and manufacturer compliance.
What immediate steps stop active leaks?
First, limit interior damage by isolating affected zones and protecting finishes. Then document leak paths, review recent weather, and call us for emergency response. We stabilize conditions, install temporary controls where code allows, and plan permanent waterproofing aligned with drawings and permits. Rapid action preserves exterior building restoration goals and prevents long-term substrate deterioration.
How will you access our façade safely?
We design access around safety, occupancy, and permitting. For façade waterproofing we use suspended scaffolding, pipe scaffolding, sidewalk sheds, and access elevators—approved methods that protect pedestrians and expedite inspections. We obtain required NYC DOB/DOT permits and after-hours variances when needed so occupied properties maintain operations across Huntington Station and New York City.
During a storm we discovered water tracking through a parapet joint into several apartments. We called after hours and your team arrived the same night, protected interiors, and mapped leak paths. Within days you replaced failed perimeter sealant lines with Sika silicone, restored coatings around terminations, and documented everything for DOB compliance. The façade has been dry since. Professional, organized, and clear communication throughout Huntington Station and New York City service.

⭐️⭐️⭐️⭐️⭐️Groundwater had been seeping through a foundation wall in our co-op’s garage. You evaluated hydrostatic pressure, recommended a negative-side assembly, coordinated third-party asbestos/environmental investigations, and secured permits so work could proceed without disrupting operations. Access and pedestrian protection were handled with suspended scaffolding and a shed. After special inspections and closeout, the wall is dry and the space usable again. Responsive 24/7 from start to finish.
