Waterproofing & Masonry in Brooklyn

Many properties in Brooklyn were built before 1940. These structures often have aging brickwork, deteriorated mortar, and unprotected foundations. Without proper waterproofing, basements develop leaks, and moisture slowly damages structural integrity. Masonry issues, such as crumbling joints or flaking brownstone, worsen with each passing season.

This guide explains what waterproofing and masonry services include, common issues in Brooklyn, and how to protect your home. Whether you're maintaining a brownstone or fixing foundation cracks, you'll find answers to the most important questions homeowners face.

Waterproofing is the process of preventing water from entering a structure. It protects basements, foundations, and walls from seepage and flooding—especially important in Brooklyn, where older homes are prone to leaks.

Interior waterproofing includes sealants, vapor barriers, French drains, and sump pump systems. These systems control water inside the basement.

Exterior waterproofing involves membranes, drainage systems, and foundation coatings. These solutions prevent water from reaching the building.

Waterproofing benefits include:

• Prevents foundation damage
• Stops mold and mildew growth
• Protects belongings in basements
• Increases home value
• Improves air quality indoors

Brooklyn homes, particularly brownstones, need proactive waterproofing due to aging construction and porous brickwork.

Masonry involves the construction and repair of structures using materials like brick, stone, or concrete. In Brooklyn, most brownstones and row houses rely heavily on masonry for both structural stability and aesthetic appeal.

Key masonry services include:

• Brickwork repairs for cracked or loose bricks
• Repointing (brick pointing) to fix deteriorated mortar joints
• Brownstone repair to restore damaged facades
• Concrete patching for foundations, steps, and sidewalks

Masonry contractors in Brooklyn play a crucial role in preserving the city's historic homes. Proper masonry work not only enhances the property's curb appeal but also protects it against water infiltration and structural weakening. Brownstones are especially vulnerable due to soft stone materials and decades of exposure. Masonry restoration keeps these homes both beautiful and strong. 

Brooklyn homeowners frequently encounter water and structural damage due to aging infrastructure and harsh weather conditions.

Common issues include:

• Basement water seepage from cracks or poor drainage
• Foundation cracks from settling or hydrostatic pressure
• Crumbled mortar joints needing brick pointing
• Spalling bricks (surface peeling from water damage)
• Brownstone decays from freeze-thaw cycles
• Mold and damp odors in lower levels

These problems are most visible in older homes, especially pre-war brownstones and brick rowhouses. Brick pointing is often necessary every 20–30 years, depending on exposure and the quality of prior work. Without it, water seeps into the walls, accelerating damage. Hire our experienced waterproofing contractors in Brooklyn for proper diagnosis and long-term repair.

Effective basement waterproofing and exterior waterproofing systems prevent costly structural damage and improve indoor comfort.

Interior waterproofing options:

• Sealants for walls and floors
• Sump pumps to remove water buildup
• French drains to redirect water under the slab

Exterior waterproofing solutions:

• Membranes to block moisture from foundation walls
• Drainage boards and weeping tiles for water diversion
• Proper grading around the home’s perimeter

Preventive steps also help, including:

• Cleaning gutters regularly
• Extending downspouts away from the foundation
• Fixing roof drainage systems

Waterproofing increases home value, reduces health risks, and offers long-term peace of mind—especially during NYC’s rainy seasons. All your waterproofing solutions are here at RH Construction USA Inc.

Proper masonry repair extends the lifespan of your home’s exterior. Brooklyn brownstones and brick homes require regular upkeep to prevent more severe structural issues.

Key services we provide:

• Brick pointing (repointing): Replaces decayed mortar between bricks
• Brownstone restoration: Resurfaces or replaces damaged facades
• Brickwork repair: Fixes spalling, cracks, or loose bricks
• Concrete patching: Repairs walkways, steps, or basement walls

Most pointing lasts 20–30 years, depending on the level of exposure. Brooklyn’s climate, with harsh winters and wet springs, accelerates deterioration. Routine inspections and minor fixes prevent larger problems. Maintain caulking, clean weep holes, and check for cracks after winter. Hire our licensed masonry contractors in Brooklyn to ensure code-compliant, long-lasting results.

Homeowners can handle some minor waterproofing and masonry tasks, but most structural or moisture-related issues need expert repair.

DIY tasks:

• Gutter cleaning
• Downspout extension
• Applying waterproof paint/sealant
• Caulking small cracks

Professional work:

• Basement waterproofing systems
• Structural foundation repairs
• Full repointing of brick façades
• Brownstone façade reconstruction

Licensed NYC contractors ensure compliance with local codes and safety regulations. They use the right materials and techniques for long-lasting results, which is particularly significant for landmarked properties. Attempting major repairs without the necessary experience can worsen the damage or void the insurance.

How often should brick pointing be done in Brooklyn?

Every 20–30 years, depending on exposure, weather conditions, and the quality of previous work.

Do brownstones need special waterproofing?

Yes. Brownstones have porous materials that absorb water, needing both interior and exterior waterproofing solutions.

What’s the difference between waterproofing and damp proofing?

Waterproofing blocks water completely; damp proofing slows the movement of moisture. Basement waterproofing is more effective in wet climates.

Can waterproofing prevent basement flooding?

Yes. Sump pumps, drains, and membranes stop groundwater and rain from entering basements.

How much does masonry repair cost in Brooklyn?

Costs vary. Repointing can range from $10 to $25 per square foot. Brownstone repair may exceed $100 per square foot, depending on the extent of the damage.

Waterproofing protects your home’s foundation and basement from moisture, while masonry work maintains the strength and beauty of your exterior. Both are essential in a city like Brooklyn, especially for brownstones and historic buildings.

Preventive maintenance saves money and protects your investment. Ignoring water damage or brick decay can lead to higher costs and increased risks.
