What to look for in a basement waterproofing company
Location and licensing
When hiring a company for basement waterproofing, location and licensing should be key factors. Ideally, customers should hire a business headquartered close to home and well-established in the area as that will make dealing with issues much easier.
- Service area: Most companies have a designated service area and may charge extra for those outside that geographical range.
- Contractor arrangements: Some basement waterproofing services work with approved contractors throughout a region or even the whole country. With such companies, customers must be extra cautious when hiring, as less managerial oversight can lead to poorer service.
- Licensing: Homeowners should confirm businesses and contractors are properly licensed, bonded and insured in their local area.
Before hiring a service for the job, get multiple free price quotes. There are a few other pricing factors to understand before selecting a company as well.
- General calculation method: Basement waterproofing can be costly, and pricing is calculated per foot. Other costs may be added on top of that, such as equipment and parts, product installation, labor and refinishing.
- Total cost estimate: Basement waterproofing ranges from as low as $200 to $500 for minor repairs and can be as high as $2,000 to $20,000 or more for thorough repairs.
- Lifetime guarantees: Many companies offer annual waterproofing maintenance at a reasonable rate, so ask any potential companies about their guarantees.
With waterproofing, businesses should first provide an inspection. Inspections should cover several factors.
- High level issues: These types of issues occur when water gets in through the top of the basement, such as through an improperly sealed window well. If rainwater is draining toward the house, water can also come in over the top of the home's foundation/basement wall.
- Basement wall and floor issues: Inspections should include checking the walls and floors. Many wall and floor issues that lead to water leakage, like cracking and bowing, are caused by hydrostatic pressure (when water presses against the walls). Tie rod holes, air pockets in the concrete, unsecured floor and wall joint bonding, and mortar joint openings can also allow water into basements.
- Equipment and sealant issues: Sewer pipe leaks, sump pump failures, drain clogs and other malfunctions with equipment all lead to water leakage in the basement. Waterproofing companies should check for this.
Exterior waterproofing services
Exterior waterproofing stops water penetration at the source and is considered a long-term solution.
- Roof solutions: Waterproofing companies should be equipped to install gutter systems and accompanying downspout systems, which are key to moving water away from the home.
- Ground-level solutions: Soil near the foundation should always decline away from the house. Waterproofing companies should be capable of modifying issues with the slope of soil and concrete around the house.
- Exterior excavation: If it is not possible for soil and concrete to decline away from the house, companies should be able to offer exterior excavation. This involves digging down to the foundation wall footer and then replacing the current drainage tiles or putting in a French drain (weeping tile) system.
Interior waterproofing services
Interior waterproofing stops water from entering the basement but does not stop water from draining into the home in general.
- Crack injections and wall panels: Covering gaps with polyurethane or epoxy coating can effectively prevent water from entering a basement but is not a permanent fix. Installation of plastic wall panels can also fend off water.
- Interior drain systems: The problem of hydrostatic pressure can be addressed by installing drainage tile and/or piping to route water to a sump pump system. Most reputable waterproofing companies will offer this service.
- Foundation reinforcement: Though this does not address water control, it makes it more difficult for water to cause structural issues.
It is vital to stop problems before they happen. Basement waterproofing companies should provide building owners with tips to avoid potential water leakage.
- Cracked and/or buckling walls: Cracks can be in any direction and, if they're widening, a sign of structural damage and heavy pressure. A buckling wall - when the wall is bowing inward -- is caused by hydrostatic pressure and is a strong sign that water is in the process of destroying the foundation.
- Mold, mildew and moisture problems: Mold and mildew thrive in dark, damp environments, so if there is such growth in a basement, water is getting inside. Some forms of mold are irritants that can cause serious respiratory issues, so waterproofing companies should teach customers how to identify them.
- Efflorescence: When salt migrates to the outside layer of a porous material, it forms a white, powdery coating. This occurs when water invades the basement through porous construction materials and already-present salt dissolves in that water.
What are different types of basement waterproofing?
Exterior waterproofing methods focus on preventing water from entering the house. This is accomplished through excavating, installing drainage systems, the use of gutter systems and sloping soil and concrete away from the foundation.
Interior waterproofing methods focus on moving out water that has already penetrated the home. This is accomplished through drain tile and pipe setup, sump pump installation and the use of sealant, epoxy and even foundation reinforcement.
Sealants and epoxy injection
Sealant and epoxy injections in cracks on the interior and exterior are a short-term fix. This method is inexpensive and doesn't usually require a contractor's help.
Ventilation and airflow improvement
Excess moisture and humidity can cause a home to be filled with all sorts of contaminants, from molds and mildew to toxins and odors. Many basement waterproofing companies recommend ventilation systems to push out that bad air.
Who needs basement waterproofing services?
Every homeowner with a basement should see that it's properly waterproofed to avoid problems.
Those who own and lease properties are strongly advised to waterproof their basements. If water damage gives rise to toxic mold or structural issues, there could be losses and liability.
Buildings and institutions
Hospitals, schools, firehouses and other buildings rely on the health of their structures. Annual basement waterproofing service can prevent costly repairs and structural fixes.
Before buying or renting office or warehouse space, a business should inspect for water damage and make sure the basement is adequately waterproofed. It makes financial sense and ensures employee safety.
