The Best Basement Waterproofing Companies

Keeping a basement dry is vital to the condition of a home and the health of the people inside. Wet basements can result in mold, which can cause serious health conditions—but moisture can also cause structural damage and result in property loss. For these reasons, dry basements are critical, even if they aren’t finished or habitable spaces. While keeping a basement dry might be tough, finding the best basement waterproofing company doesn’t need to be. This guide will walk homeowners through the points to consider when comparing waterproofing companies and highlight some of our favorite choices.

What to Consider When Choosing One of the Best Basement Waterproofing Companies

Whether it’s a storage space, a finished basement, or simply a room for mechanical systems like a water heater and furnace, a waterproofing company can handle the job of making a basement impervious to moisture. But there are a few things to know about these companies and their work before searching for “basement waterproofing near me.”

Service Area and Scheduling

Some basement waterproofing specialists have wide service areas, making finding contractors a breeze. Some waterproofing basement companies cover all 50 states, while others might work in specific regions. It’s best to contact companies or use search functions built into their websites to ensure they can service a customer’s home.

The company’s schedule is also an important consideration. In most cases, the company will need to assess the home to provide an accurate quote before starting the job, and this takes time to schedule and perform. The sooner a company can schedule an inspection, produce a quote, and get to the job, the better for the homeowner. Contacting the company directly or scheduling the job online can hasten the process. Keep in mind that waterproofing contractors working in flood-prone regions may have busier and slower times of the year based on environmental conditions.

Basement Inspection

Before a homeowner signs a contract to waterproof a basement, the company needs to provide an accurate quote. To do so, most companies send an inspector to the home to assess the basement. The inspector will look for serious issues like structural foundation cracks, leaks, and mold, and they should relay their findings to the homeowner in a report.

Knowing the basement condition before waterproofing will help the homeowner decide whether to proceed with waterproofing or focus their budget on repairs. In some cases, waterproofing efforts can go to waste if the homeowner doesn’t make repairs first.

Waterproofing Solutions

Like most things, there is more than one way to keep a basement dry, and most basement waterproofing companies should be adept at a few methods. Some of the best basement waterproofing methods include interior and exterior approaches.

• Interior waterproofing efforts include filling foundation cracks with concrete sealer, coating interior walls with waterproof epoxies and paints, or installing french drains around the basement perimeter.
• Exterior waterproofing methods may involve excavating along the exterior and installing drainage, installing gutters, adhering membranes to the exterior of the foundation, and more.

Also, the best basement waterproofing companies will be able to assist homeowners with dehumidification and sump pumps. Some companies even have patented systems or products that they use on every job.

Additional Repairs

Beyond the inspection and solutions, some basement waterproofing companies might even offer repair services. These companies are typically foundation specialists, and they’ll have the equipment to excavate and repair foundation walls and basement floors.

Also, mold is reasonably common in wet basements, but not all basement waterproofing companies are equipped to handle serious infestations. Suppose the inspection uncovers lots of mold and it’s beyond the company’s scope or capability. In that case, homeowners might need to handle remediation separately or hire a company to remove the mold and handle the waterproofing.

Warranty

Homeowners considering hiring a basement waterproofing company should compare warranties. Many of the best companies will offer long-running warranties that will protect a homeowner from faulty products or craftsmanship. Should there be a leak or moisture problem moving forward, the company will come back and readdress the issue.

Note that not all companies’ warranties are the same. Some might cover several years, while other companies might offer limited lifetime warranties. Some warranties might even be transferable, and this one point can add a few extra dollars to the sale price if the house goes on the market.

Also, when a company uses a specific product, it’s important that the homeowner finds out what the manufacturer’s warranty entails.

Customer Support

As with any investment in a product or service, homeowners should seek out companies with reputable and reliable customer service. The best basement waterproofing companies have customer service readily available. Company websites will include contact numbers and email addresses that homeowners can use to contact a person, not just contact forms on the company’s “About” page.

Before You Hire One of the Best Basement Waterproofing Companies

More goes into hiring a company for waterproofing the basement than one might expect. Even with a trustworthy contractor, consider some factors before giving them the go-ahead.

• Contractors should offer free quotes. If not, move on to the next contractor.
• Be sure to ask for proof of insurance, business license, and trade license. Individual states have different requirements, so be sure to know which license your waterproofing contractor might need to carry.
• Ask for references. Basement companies with enough time in the industry should have a portfolio of projects they’ve finished and contact numbers of past customers.
• Ask for an in-depth description ahead of time of what the contractor will do. Folks who get multiple quotes will be able to compare these plans and possibly determine which of the contractors is the most qualified.
• Ensure any active leaks or ongoing water damage have been treated by one of the best water damage restoration services before beginning basement waterproofing.

The answers to these questions can go a long way to determining whether or not a particular basement waterproofing contractor is worth working with.

Cost of Hiring One of the Best Basement Waterproofing Companies

Basement waterproofing costs can vary depending on the size and method, but they generally range between $2,250 and $7,063, with the national average at about $4,539.

Larger basements or basements that will require excavation to keep the moisture and water at bay will be on the higher end of the scale. For more straightforward fixes like crack repairs and waterproof coatings, the cost of materials and labor is considerably less, landing the job on the lower end of the scale.

Also, it’s a good idea for homeowners to budget a bit of extra money for incidental expenses that come up along the way. For example, if a contractor digs around the foundation to install a drainage system and finds a structural issue, it will most certainly cost extra to make that repair.

The Advantages of Using One of the Best Basement Waterproofing Companies

The best basement waterproofing companies can give residents some peace of mind that their home is healthy and safe. Since these companies can help prevent mold and mildew, the folks living in the home will be able to breathe easier and may have fewer allergic reactions and long-term health concerns.

FAQs

That’s a solid foundation on the best basement waterproofing companies, but even so, there might still be some cracks or questions. The following includes some of the most common questions asked about this industry, so be sure to check for an answer to your question listed below.

Q. How much does basement waterproofing cost?

Basement waterproofing typically costs between $2,250 and $7,063, with a national average of around $4,539. The size of the basement, the severity of the issues, the repairs required, and the method of waterproofing will determine the cost.

Q. Do basement waterproofing companies offer a guarantee?

Many waterproofing companies offer a warranty on their products used and the labor involved.

Q. How long does basement waterproofing take?

Typically, basement waterproofing takes about 3 days. Projects requiring more extensive repairs will take longer, and more straightforward jobs (particularly in new construction scenarios) can take less time.

Q. How long does basement waterproofing last?

The average basement waterproofing job lasts about 10 years before requiring attention, a new coating, or replacing the drainage system.

Q. Can I waterproof my basement on my own?

There are waterproofing methods that DIYers can use, such as applying concrete sealer, epoxy paints, and crack repair sealants. However, these are best as preventive measures, where actual causes might require a professional’s attention.

Q. Why does my basement leak when it rains?

There are a few reasons a basement might take on water during a rainstorm. First, if the gutters aren’t draining well, water will overrun the edge and fall next to the foundation, allowing it to seep through the porous concrete. Also, areas with high water tables exert a lot of hydrostatic pressure on foundations, squeezing water through the basement’s foundation and cracks.

Q. Do I get a free inspection when I hire a basement waterproofing company?

Most companies do offer free inspections and quotes, allowing users to shop several contractors before making a decision on which company to choose.
