If you've found water in your basement, you may be wondering: "Can I fix this myself and save some money?" The answer is sometimes. There are a few small jobs that many homeowners can do on their own. However, larger water problems usually require professional waterproofing. The most important thing is to understand what's causing the water to enter your basement. If you fix the wrong problem, the leak may simply come back. In this guide, we'll explain which basement waterproofing jobs you can do yourself and when it's better to call a professional.

Start by Finding the Source of the Water

Before buying waterproofing products, try to figure out where the water is coming from. Ask yourself:

Does the basement only get wet after heavy rain?
Is water coming through a crack?
Is the wall damp all the time?
Is there a plumbing leak?
Is there a musty smell but no standing water?

Knowing the cause of the problem will help you choose the right solution.

DIY Jobs Many Homeowners Can Do

Some simple maintenance tasks can help reduce basement moisture. These are often good projects for homeowners.

Clean Your Gutters

Clogged gutters are one of the most common causes of basement water problems. When gutters overflow, rainwater falls beside your foundation instead of flowing safely away. Cleaning your gutters several times a year can help reduce the amount of water around your home.

Extend Your Downspouts

Downspouts should carry water several feet away from your foundation. If they empty beside the house, the soil around your basement can quickly become saturated. Adding downspout extensions is a simple project that many homeowners can do themselves.

Improve Drainage Around Your Home

Take a walk around your house after a heavy rain. Does water collect near the foundation? If so, improving the grading around your home may help water drain away instead of pooling beside the basement walls.

Keep Window Wells Clean

Leaves, dirt, and debris can block drainage inside basement window wells. If water builds up there, it may leak through the basement window. Cleaning window wells regularly is simple and can help prevent leaks.

Seal Small Gaps Around Pipes or Windows

Sometimes water enters through small gaps where pipes or utility lines pass through the wall. In some cases, these small openings can be sealed to help reduce moisture. However, if water continues entering after sealing the gap, there may be a larger problem that needs professional attention.

What DIY Waterproofing Usually Won't Fix

Some basement problems require more than a simple repair. For example:

Water coming through foundation walls
Water entering after every heavy rain
Large foundation cracks
Flooding
Bowing basement walls
Hydrostatic pressure
Ongoing moisture problems

These situations often require specialized waterproofing systems.

Does Waterproof Paint Stop Basement Leaks?

Many homeowners buy waterproof paint hoping it will solve the problem. While waterproof paint may improve the appearance of basement walls, it usually does not stop water from entering. If water continues pushing through the foundation, paint alone won't solve the underlying issue. It's important to fix the source of the water—not just cover it up.

Can I Repair a Foundation Crack Myself?

Some very small, non-structural cracks can be repaired using products sold at home improvement stores. However, if the crack:

Is getting larger
Leaks water
Is horizontal
Appears in several places
Is part of a larger foundation problem

it's best to have it inspected by a professional.

When Should You Call a Waterproofing Professional?

You should consider calling a professional if you notice:

Water entering after heavy rain
Water on the basement floor
Large foundation cracks
Damp basement walls
Mold growth
A strong musty smell
Water coming through several areas
A basement that stays wet even after simple repairs

A professional can identify the source of the problem and recommend the most effective solution.

Is Professional Waterproofing Worth It?

For many homeowners, yes. Professional waterproofing can help:

Keep your basement dry
Protect your home's foundation
Prevent mold growth
Reduce humidity
Protect finished basements
Prevent future water damage

While it may cost more than a DIY repair, it often provides a much longer-lasting solution.

How Can You Help Prevent Basement Leaks?

Even if you hire a professional, regular maintenance is still important. Here are a few simple habits that can help:

Clean gutters every spring and fall.
Keep downspouts pointed away from the house.
Check window wells regularly.
Repair plumbing leaks quickly.
Test your sump pump before heavy rain.
Inspect your basement several times a year.

These simple steps can help reduce the chance of future water problems.
