Basement Waterproofing Cost


How Much Does Basement Waterproofing Cost?

A substantial amount of water in a cellar or basement of your home can cause some serious problems. It may damage heating equipment, laundry appliances, or flooring. Basement waterproofing can provide a variety of solutions, and it's crucial that you identify the right way to stop leaks in a specific home as water can come from many different sources.

A contractor might waterproof a cellar by sealing cracks, covering leaky windows, installing roof gutters or adding a sump pump with drains. Some problems, however, can't be eliminated without excavating the ground to gain access to an exterior wall.

What Major Factors Affect The Cost To Waterproof a Basement?

The source of the moisture and the number of entry points will make a big difference. If a professional discovers that the problem is actually linked to condensation, you may only need a dehumidifier. In comparison to moisture from the roof or lawn, it's often more costly to stop water from seeping in through soil.

You also need to think about any objects that block access to the cellar walls. The cost to waterproof a basement will rise if a deck or a heavy fuel tank must be removed. Here are some of the main factors that can affect your overall basement waterproofing costs:

  • type of leakage
  • number of leaks
  • obstructions
  • pavement and landscape slopes
  • ground and storm water

Basement waterproofing today is being performed by professionals who steer homeowners to an interior and exterior water control solution as, interestingly enough, waterproofing begins at the top. We highly recommend getting in touch with professionals in your area to get the best advice possible.

Cost Breakdown For Basement Waterproofing

Pricing techniques differ significantly depending on the services provided and your regional location. Contractors might bill you by the linear foot or square foot for your basement waterproofing. Most homeowners should expect this project to cost in the region of about  $5,000. However, multiple leaks, obstructions, and other complexities often push the price higher.

Thorough waterproofing is more likely to deliver a long-term solution and increase a home's resale value. For some homeowners, the cost to waterproof a basement can come in anywhere between $11,000 and $15,000 for a large cellar that needs exterior excavation. In extreme cases, excavation can be in excess of $30,000.

Different Waterproofing Methods

Each service provider may offer different solutions depending on their equipment and the skills of its employees. Painting walls with waterproof paint is relatively inexpensive, but seldom an effective way to really waterproof a basement. A sump pump with drains is moderately costly as it removes excess water, but it doesn't eliminate the source of this moisture.

Some types of cellar walls can benefit from crack injections. On average, they cost around $400 each. External excavation and sealing is usually the most successful method, but it's more expensive than all of the alternatives.

How Much Will It Cost To Waterproof My Basement?

It's comparatively inexpensive to seal cellar windows or repair faulty gutters. On the other hand, external excavation for your basement waterproofing will greatly increase the price as heavy equipment will be needed and a permit may also become necessary.

Consider the following variations in the cost to waterproof a basement:

  • Labor: Most solutions involve substantial amounts of work. If it's a relatively small project, you can plan on paying about 65% of the bill to cover labor costs.
  • Sealants: Many fixes involve the use of a rubberized sealant. A gallon of this compound sells for around $10 - $14.
  • Slope: Simply changing the slope of the ground can make a significant difference by redirecting runoff from your home. Purchasing ground soil usually costs $40 - $150 per 5 yards depending on your location and soil quality. Hiring a professional to create a slope will add another $50 - $150.
  • Gutters and downspouts: Installing rain gutters and extending downspouts can be a cost effective solution for many by redirecting rainwater away from the foundation. Above ground downspouts of 3-25 ft cost $10 - $50 each. If you want to extend downspouts into below ground drainage pipes or dry wells, expect to spend $100 - $400 on materials. If you allow a professional to handle the job, you could pay between $200 - $2,000.
  • Dehumidifier: Dampness from condensation in the basement can be easily resolved with the help of a dehumidifier. On average they cost $150 - $400. Larger basement areas will require a larger capacity dehumidifier which retails for slightly more, $800 - $1,200.
  • Sump pump: Since the above solutions aren't going to work for major flooding in the basement, you may have to install a sump pump. These cost between $100 - $300 for just the unit, and $250 - $600 including installation. If you require perimeter drains to reroute water toward the pump, you could spend $2,000 - $6,000. In some instances, this cost to waterproof a basement could be upwards of $10,000 - $15,000.
  • Excavation: In the worst case scenario, excavation around the exterior basement wall will be required. After this, sealers and moisture barriers are applied to the wall as well as the installation of exterior footer drains around the perimeter. A professional completion of this job starts at $5,000, but  and can quite easily cost you more than $30,000 in a worst case scenario.

Keep in mind that the cost to waterproof a basement also varies based on what state or city you live in. This will determine how many contractors you have to choose from. Local permit requirements, water tables, and soil composition could also affect rates. Major basement waterproofing projects often involve heavy equipment and multiple trips in large trucks, so your region's diesel prices and vehicle taxes may have an impact as well.
