Best North Carolina Basement Waterproofing Contractors

Top Services

Basement waterproofing companies perform a variety of services. Here are some of the most common:

• Exterior waterproofing membrane: They will install a membrane outside of your basement or foundation to prevent water intrusion.
• Weeping tiles (sometimes called a French Drain): Your waterproofing company will install a drain system underground to prevent too much water from building up in the soil next to your house, helping prevent flooding in your basement.
• Crawlspace encapsulation: A waterproofing company will line the crawlspace under your home with a waterproof membrane and install a dehumidifier, keeping the crawlspace free of water and moisture.
• Basement crack repair: The waterproofing company will use a heavy-duty sealer, often epoxy, to seal up any cracks in your basement.
• Sump pump: They will install a sump pump and drainage system to pump out any water that finds its way into your basement.
• Gutters and downspouts: Many basement waterproofing companies also install rain gutters and downspouts to properly funnel water away from your home so it doesn’t enter your basement.
• Damp proofing: Damp proofing keeps out most soil moisture without completely blocking out heavy rainwater. Most waterproofing companies can perform this service at a lower cost than complete waterproofing.

This is only a sample of the services a professional basement waterproofing company can perform for you. By having your basement or crawlspace sealed up, you can prevent damage to your home and make the space more usable.

Tips For Hiring A Professional

Having your basement waterproofed can cost quite a bit of money. That’s why you need to be careful when looking for a professional basement waterproofing company.

Get Multiple Quotes

You should get multiple quotes before hiring a basement waterproofing company. The first one you get a quote from may be the best, but you won’t know until you compare them to others. Make sure to ask about any additional costs you may incur, and get details to be sure they are calculating for all the work you need.

Make sure to compare prices carefully. Any prices far cheaper than the others may be a red flag. It’s possible they use lower quality materials or lack the experience necessary to perform quality work. Check their reputation on Best of the Web to make sure they are trustworthy.

Make Sure They Offer A Warranty

Most basement waterproofing companies offer a warranty to cover their work. While some only cover the materials used, some also cover the labor. Find out what their warranty covers if they offer one. You may ultimately decide on a lower priced company that offers a shorter warranty, but it is at least something you should account for when comparing.

Frequently Asked Questions

Can I Waterproof My Basement Myself?

There are some waterproofing steps you can take on your own. You can apply waterproofing sealer to the interior walls of your basement, seal a crack, or install a sump pump. Many of the materials you use may not be the same long-lasting, high-quality materials a professional would use.

While you could save some money by going the DIY route, there is a risk you may not do as complete of a job as necessary to prevent damage. You may not want to run that risk only to save a small amount by doing the work yourself. Most of the time this is something best left to professionals.

Should Basement Waterproofing Companies Be Licensed?

Most states do not require a specific license to install waterproofing. However, most require a contractor license for work on your home, which includes waterproofing. 

Even if your location doesn’t require a license, you should ask if the company has any special training or certifications. Some manufacturers of waterproofing products offer training on how to install their product.

How Long Does Basement Waterproofing Last?

How long basement waterproofing lasts depends on what type of waterproofing you had done and the quality of the materials. Minor interior work may last only ten years or so, while some exterior work lasts much longer. With any type of waterproofing, proper installation can extend the life. Most basement waterproofing companies offer around a ten year warranty on their work. Make sure to ask about the warranty and the quality of materials when getting quotes.
