Our Services

Foundation Repair

We repair foundation cracks, address foundation settlement, lean walls back into place, and fix damage created by hydraulic pressure from the soil around your home and water.

We determine why your foundation is failing and install solutions to stop further foundation issues.

Foundation cracks that look like stairs in your bricks or blocks, doors and windows not opening or closing properly anymore, cracked walls or uneven floors or gaps between walls and ceilings all mean your home foundation is moving where it shouldn’t be and needs repair before it gets worse.

We use helical piers, foundation piers, carbon fiber strips, wall anchors, crack filling and underpinning methods to secure what’s been moved. We choose the best method for your situation as well as Alexandria’s soil conditions. Our foundation repair specialists handle everything from minor foundation cracks to major structural repairs.

Basement Waterproofing

We stop water from intruding through the walls, floors and joints. We manage subsoil water pressure and make your space dry and workable. We can provide interior or exterior basement waterproofing solutions based on your home’s needs.

You may notice water on your floor after every rain storm, wet walls, musty odors in corners or white powder on block walls from efflorescence or mold growth. These issues become worse over time and can end up damaging your belongings, air quality in the home and property value.

We install interior drains, vapor barriers and sump pumps as necessary or dig out around the perimeter of your home to seal holes on the outside or repair cracks. We utilize an individualized approach based on how water is coming in—inside or from outside.

Crawl Space Repair

We fix bouncy floors, broken floor beams, sinking support posts, and water-damaged wood. We make the structure strong again so the floors above are level and solid once more.

You may have bouncy or sloping floors, cracks in your walls or doors that won’t shut. These issues often mean that the supports are compromised due to water, soil movement, or bad construction.

We install adjustable steel posts, replace damaged beams, sister floor beams, and level floors. We reconstruct the support system to bear the load properly. Our structural engineers handle repairing damaged foundations in crawl spaces throughout Alexandria.

Crawl Space Encapsulation

We seal from ground water, control humidity, and prevent wood rot and mold. This differs from structural repair as this focuses on the long term without moisture intrusion.

You may have standing water, elevated humidity, musty odors entering your home, or mold on joists. Alexandria’s clay soil and high water table create incredibly common situations with moisture.

We install vapor barriers, seal vents, add dehumidifiers, and lay drainage mats. We transform the space into a dry, controlled environment that protects the area above.

Sump Pump Installation

We install sump pumps that collect water from drains and pump it away before it can flood. We install both primary pumps and backup battery-operated pumps.

You need a sump pump if you’ve had flooding before, water collects at your home, or your old pump isn’t operating well during heavy rains. Many homes in Alexandria have no sump pump or one that’s too small.

We install pumps sized appropriately for your home’s water needs, battery backups for power outages, and alarms to notify you if the pump fails. We connect the pump with interior drainage to form a complete system.

French Drain Installation

We install French drains that collect underground water around your home and divert it before it enters. We install inside and outside French drains based upon your home’s structure and drainage needs.

You need a French drain if your home weeps, the soil around your property is perpetually damp or yard drainage is poor and slopes toward your home. Alexandria’s clay soil does not absorb excess water well so proper drainage is key.

We excavate trenches, lay perforated pipe in gravel and connect to a sump pump or outside drain. We design the system for the water flow needs and soil on your property.

Homeowner FAQ'S

The most common signs are foundation cracks in walls/floors, doors and windows don’t open/close properly, uneven/sloping flooring, separation between walls and ceilings and water entering. If you recognize any of these indicators, have a foundation specialist or structural engineer assess it to determine the cause and severity.

Alexandria is known for its clay earth which does not properly absorb water. Alexandria has a high water table due to proximity to the Potomac River and many older houses were built without modern measures. Heavy rains, improper grading, and underground water pressure assist in transmitting water into homes.

Foundation repair costs depend on damage severity and needed solutions. According to Forbes, foundation repair Alexandria VA typically ranges between $2,000-15,000 depending on intervention needs. Small crack infills and concrete repair are less expensive than more invasive jobs such as installing piers or wall anchors. Foundation contractors provide a clear price after assessing your home to let you know what to expect. Services like concrete leveling may also be needed.

It depends on the cause and your policy. If a pipe bursts it’s sudden enough that an insurance company may cover it—but settling or prolonged water entry is usually deemed by insurance companies as something that occurs over time and is not covered. Assess your personal policy for any specifics. We can provide documentation should you need assistance with any claims.
