Services Overview - Basement Man Waterproofing
Comprehensive Waterproofing
For Blue Point and Suffolk CountyBasement Man Waterproofing provides a full range of moisture control and foundation services designed to keep basements dry, safe, and usable. Our services address the root causes of water intrusion, preserving structural integrity and indoor air quality. With decades of experience in Long Island’s unique environment, we deliver tailored, reliable solutions—whether you need a simple sump pump replacement or a complete exterior waterproofing system.
Professional Waterproofing Services Matter
Water in the basement creates multiple, compounding problems: mold growth, wood rot, corroded HVAC systems, damaged belongings, and foundation deterioration. Moisture can hide behind finished walls and under flooring, causing hidden damage that grows over time.
Professional waterproofing identifies underlying causes—poor drainage, hydrostatic pressure, foundation cracks—and applies systems engineered to prevent repeat problems. Investing in professional waterproofing is an investment in your home’s longevity and your family’s health.

Sump Pump Installation & Replacement
1. Waterproofing (Interior & Exterior)
We design and install both interior and exterior waterproofing depending on the situation.
- Interior Systems: Perimeter drain installations, French drains, and sump pumps to collect and move water away.

- Exterior Systems: Excavation and membrane installation to keep water from penetrating foundation walls.
- Vapor barriers and insulation recommendations to create a dry, energy-efficient space.
Why this matters
Interior methods are often faster and less disruptive while still addressing hydrostatic pressure; exterior methods provide the best long-term protection for severely compromised foundations or chronic exterior seepage.
2. Mold Treatment & Remediation
Moisture always precedes mold. We provide thorough mold assessment, containment, removal of impacted materials where necessary, and treatment using industry-accepted products and procedures. Our process includes:
- Moisture source control (critical for long-term resolution)

- HEPA-filtered containment and negative air setups for larger projects
- Antimicrobial treatments and, when necessary, controlled removal of contaminated materials
- Post-remediation verification to ensure successful treatment
Why this matters
Interior methods are often faster and less disruptive while still addressing hydrostatic pressure; exterior methods provide the best long-term protection for severely compromised foundations or chronic exterior seepage.
3. Foundation Crack Repair
We repair structural and non-structural cracks using proven techniques such as epoxy injection, polyurethane foaming, and mechanical stabilization where needed. Each repair begins with a thorough structural assessment to determine the best method.
Why this matters
Cracks allow water in and can progress if left unaddressed. Proper repair restores structural integrity and prevents future leaks.
4. Sump Pump Installation & Replacement
Sump pumps are critical to an interior drainage system. We install reliable, high-capacity primary pumps and offer battery backup systems to protect your home during power outages. Our installations include durable basins, high-quality pump models, and proper discharge routing to keep water away from the foundation.
Why this matters
A functioning sump pump is the last line of defense against basement flooding. Proper installation and backup systems are essential, especially during storms that can coincide with power loss.
5. Moisture Control Repair & Maintenance
Beyond installations, we provide repair services for failing systems—clogged drains, cracked pump basins, inadequate discharge, and damaged membranes. Regular maintenance plans are also available to help homeowners avoid emergencies.
Why this matters
Preventive maintenance extends system life and identifies small issues before they become costly repairs.

FREQUENTLY ASKED QUESTIONS
How do I know if I need interior or exterior waterproofing?
We determine the best approach during an inspection. Interior systems can often address hydrostatic pressure effectively with less cost and disruption. Exterior systems may be necessary when there’s chronic exterior seepage or when the foundation membrane has failed.
How long do waterproofing systems last?
Lifespan depends on the system and local conditions. Interior drainage systems and high-quality sump pumps can last many years with proper maintenance. Exterior membranes, when properly installed, offer decades of protection. We provide maintenance schedules and warranty details for each system.
How much does waterproofing cost?
Costs vary widely based on system type, basement size, excavation needs, and repair complexity. We provide a written estimate after inspection with clear options and explanations.
Can you install a sump pump in a finished basement?
Yes. We install pumps in finished basements with minimal disruption—often working within the basement to avoid exterior excavation when feasible. We protect flooring and restore impacted areas where necessary.
Do you offer financing?
We can discuss financing options available through third-party providers to make projects more accessible. Ask our office for current financing programs.
