Our Waterproofing & Foundation Services

We handle every type of water problem and foundation issue your home has. Each solution is built for the soil and weather conditions in this area.

Interior basement waterproofing installation

Basement Waterproofing

Water gets into your basement through cracks, joints, and porous concrete. Clay soil holds water right against your foundation walls. When it rains hard or snow melts fast, that water pushes inside. We install interior drainage systems that catch water before it hits your floor. We do exterior waterproofing that blocks water at the foundation wall. We handle wet basements, active leaks, flooded basements, and moisture problems in both homes and businesses. If water is getting in, we find where and we stop it. Basement waterproofing in Gaithersburg MD starts at the entry point, not the stain. A basement that leaks in one place is usually failing along the whole wall. Every basement in Gaithersburg MD is a little different, and the basement itself tells us where to start.

Foundation crack requiring structural repair

Foundation Repair

Foundation cracks, bowing walls, and settling happen when soil moves under your home. Clay soil expands when wet and shrinks when dry. That cycle never stops, and your foundation takes the hit. Cracks get wider. Walls push inward. Floors become uneven. We use epoxy injection to seal cracks. Carbon fiber strips stop bowing walls from moving. Pier systems lift and stabilize settling foundations. Every repair goes after the cause — not just what you see on the surface. Foundation repair and basement waterproofing solve two halves of the same problem, and most Gaithersburg MD homes need both.

Crawl space structural repair

Crawl Space Repair

A wet crawl space causes problems you feel upstairs — sagging floors, musty smells, higher energy bills. Moisture rots floor joists and weakens supports. We fix the structural damage first. We replace rotted beams, reinforce supports, and stabilize your foundation. Then we address the moisture so the damage doesn't come back. If your floors feel soft or bouncy when you walk, your crawl space probably needs work. Crawl space work and basement work run together here. A damp crawl space feeds the basement above it, and the basement never dries until both are handled. Basement waterproofing has to cover both.

Sump pump installed in basement

Sump Pump Installation

Sump pumps take water out of your basement before it floods your space. You need one if water comes up through your floor, your area floods during storms, or your current pump can't keep up. We install new systems sized for your home. We replace old pumps that are failing. We add battery backups so your basement stays protected during power outages. A sump and a discharge line are one part of the basement solutions, not the whole answer. The basement waterproofing around it does the rest.

French drain system along foundation

French Drain Installation

French drains move water away from your foundation before it gets inside your basement. Interior drains run along your basement perimeter and send water to your sump pump. Exterior drains redirect groundwater before it reaches your walls. Clay soil doesn't drain on its own. Water just sits there and pushes against your foundation. A French drain gives that water somewhere to go. Interior drainage and outside grading are two different solutions to the same pressure, and the basement decides which comes first.

Crawl space with vapor barrier encapsulation

Crawl Space Encapsulation

Encapsulation seals your crawl space completely from ground moisture and outside air. We install heavy-duty vapor barriers on the floor and walls. We seal vents. We add dehumidifiers to control humidity all year. A sealed crawl space means no mold, no wood rot, no musty smells coming through your floors. Your air quality gets better. Your energy bills go down. A dry basement changes how the whole home feels, not just the room below it. That is the point of waterproofing a basement properly in Gaithersburg MD.

Why Basements Here Stay Wet

10+ Years of Experience

Bros Basement Waterproofing

Water in your basement after a storm? Damp walls that won't dry? That musty smell coming from downstairs? These are signs your foundation is letting water in. Clay soil holds water instead of draining it. When it rains, that water pushes against your foundation and finds a way inside. That is where basement waterproofing has to start in Gaithersburg MD, because the water is already past the wall. Waterproofing from inside the basement is what catches it before the basement floods again.

Most homes in this area sit on soil that expands when wet and shrinks when dry. That constant movement stresses your foundation year after year. Cracks form. Water gets in. It gets worse every season you wait. Flooding does not announce itself. The basement just gets damper each year. Basement waterproofing early is the cheap version, and it keeps the basement usable.

We've worked in homes all across the area — older houses, newer builds, everything in between. Every property has different soil conditions and drainage patterns. We know what causes water problems here because we fix them every day. Gaithersburg homes share the same failures street to street, so the repair work repeats too.

Seasonal rain, snowmelt, and temperature swings all push water toward your foundation. If your basement is wet, it won't fix itself. The longer you wait, the more it costs. A small basement repair now costs a fraction of the bigger job later.

Frequently Asked Questions

Got questions? Here are the ones we hear most from homeowners.

A patch covers one spot. Waterproofing solves the whole problem — where water enters, why it keeps coming back, and how to stop it for good. We install drainage, pumps, and barriers that work together as a complete system. A patch might hold for a few months. A waterproofing system protects your home for years. A basement system installed properly outlasts the crawl space beside it, and keeps the basement dry through a Gaithersburg MD winter.

Yes. We come to your home, inspect your basement, foundation, and crawl space, and give you a detailed written estimate. No cost. No obligation. You get clear pricing and an honest explanation of the problem before any work starts.

The most common signs are water on your basement floor after rain, damp or musty smells, visible cracks in your foundation walls, white mineral deposits on concrete, and moisture in your crawl space. The clay soil and seasonal weather here make these problems especially common. If you see any of these signs, it's worth getting a free inspection before the damage spreads. Waiting turns waterproofing into structural work, and a wet basement into flooding.

Most jobs take one to three days depending on the size of your home and what's needed. Some projects like a sump pump install can be done in a single day. Bigger jobs like full interior drainage take a bit longer. We give you a clear timeline during your free inspection so you know what to expect.

Yes. Every job comes with a warranty. If something isn't right after we're done, we come back and fix it at no extra cost. You also get maintenance guidance so your system keeps working the way it should. Annual checks keep the basement waterproofing doing its job. A basement is only as dry as its last service visit.
