Why You Should Waterproof Your Basement

Leaking or damp basements can do some real damage to the overall structure of your building. This in turn would mean a drop in the value of your property and create a relatively unsafe place to live in.

Excessive moisture can also bring about mold formation and bacteria. Both of these have proven to be health hazards that can spike health problems like asthma.

That being said, you wouldn’t want to go in blind, so assessing the problem and figuring out how much the job would cost should be among the first steps you take.

Let’s take a look at the averages.

Estimated Cost Of Basement Waterproofing

Going by industry estimates, waterproofing your basement would pinch between $1,900 to $6,500 from your wallet. If the job is very extensive, then you could spend as much as $10,000 on waterproofing.

If it’s a minor fix, you probably wouldn’t spend that much. A sum of around $600 should do the trick.

You may be wondering why the huge gap in prices, as there’s quite some distance between $600 and $10,000. These all depend on the unique variables that influence the bill.

Let’s briefly examine these variables that influence the cost of waterproofing your basement. With these in mind, you can determine on average how much you will need to part with.

Estimating The Cost Of Waterproofing Your Basement

Among the factors that influence the cost of basement waterproofing include the size of the basement, what the main issue is, and the items or expertise you will need to fix it.

Here’s how you can estimate the cost.

  1. Determine where the problem originates from

Before you can draw up a budget, you will need to first know exactly what you’re dealing with. If you can’t determine the source of the problem, then you can’t come up with an accurate budget.

Here are a few causes of moisture in your basement.

  • Poorly installed downpipes
  • Missing gutters or downpipes
  • Drying a huge amount of wet laundry
  • Leaking pipes
  • Cracks in your foundation
  • Poorly graded slopes around your building
  • Poorly made window wells
  • Groundwater

The moment you can determine the root causes, you can have a fair idea of how much it would cost you to fix them.

  1. Understand the various solutions

For each cause of moisture, there are different solutions you can apply. Some fixes may even require a combination of two or more solutions. And this all depends on the extent to which dampness has consumed your basement.

Here are some of the possible solutions.

Using dehumidifiers: For minor dampness issues, you can use a dehumidifier to solve the problem. You can buy one from a store near you, and it can be used to treat small amounts of basement moisture.

Dehumidifiers will cost you between $1,200 to $2,000 to install.

For more severe moisture issues, you will need a more thorough solution.

It is worth mentioning that using a humidifier to fix a moisture issue that comes from the exterior can worsen the problem.

Drying out the air inside the basement can draw more water through the walls, and this can lead to concrete spalling, efflorescence, and other problems with your interior finishing.

Use Waterproofing products: Waterproofing products can serve as a quick solution to dampness in your basement.

There are several brands of waterproofing paints and sealants you can buy to do the trick. These products can be applied over your basement’s interior and are effective in preventing moisture from creeping through your basement walls.

The simplicity of this solution reflects very well how much it will cost you. Between $30 to $200 should be enough for cans of paint, as well as labor cost.

This solution is great, but it only keeps the moisture out of your basement, but not out of the wall’s interior. For this reason, you should combine this solution with other moisture prevention methods.

Install your gutters and downpipes the right way: Poorly installed, damaged, or missing downpipes and gutters will cause all the water coming from your roof to trickle into your building’s foundation, and into your basement.

The cost of installing new downpipes or gutters will range anywhere between $500 to $1,400. Though this depends on the size of your home.

If there’s already a gutter system installed, then all you need to do is fix the damages. This won’t cost you as much as the figures above. Expect to spend between $50 to $200, and this also depends on the severity of the damage.

Install window and well drains: If the cause of the dampness in your basement is poorly designed window wells, then a quick fix would be to install window drains.

A window drain system will cost between $500 to $2,500. That’s a decent amount of money to part with, but it is a very effective solution.

Grading your lawn: A garden lawn that slopes towards the direction of your home can channel water into the foundation and then into the basement.

A simple solution to this is to grade the lawn to a leveled surface so the moisture can remain stagnant, instead of gliding towards your basement. Re-sloping our lawn would cost around $800 to $3,000.

A lot of people may not want to do this because it can change the face of the lawn, but it’s much better than having a soaked-up basement.

Then again, a professional landscaping service will get the job done right so you have nothing to worry about.

This is not the most effective stand-alone solution, so you need to back it up with other water preventive measures.

Install a French drain: An exterior French drain system can work well against moisture. This is used to channel incoming water away before it reaches the basement.

They should be installed around the perimeter of your building for the best results. This will cost you around $1,300 per 50 feet. 

The good news is, you can equally install the drains within the basement. But be prepared to pay a few extra hundred dollars for it.

Install a sump pump:  Installing a basement sump pump system costs between $500 to $1,000. This figure is largely dependent on the number of pumps you will need.

Repairing cracked foundations: If you have cracks in your foundation that allow water to creep through, then they will need to be fixed.

This should cost you between $400 to $1,000. This depends on the number of cracks you’re dealing with, and the type of materials you want to use.

Basement Waterproofing Cost Per Linear Foot

Basement waterproofing costs per linear foot are also dependent on several factors. These include the severity of the damage, the waterproofing materials being used, and the wages you will pay the workers.

Nonetheless, we can give you some estimates based on current industry standards.

For exterior basement waterproofing per linear foot, you should expect to spend between $100 to $300. While for interior basement waterproofing, you will spend around $70 to $20 per linear foot.

Basement Waterproofing Average Cost Per Square Foot

The cost of basement waterproofing per square foot ranges between $3 to $9.

The exact amount you will pay depends on the quality of materials being used for waterproofing, as well as the service charges of the workers.

Speaking of service charges, it would be wise to find a reputable contractor to handle the job. Indeed, the more renowned experts will likely charge more, but it will all be worth it since they’ll do a great job.

Remember, basement waterproofing should be taken seriously, and you don’t want to pay a quack to do the job, only to re-do it again after some time due to a poor job done in the first place.
