Waterproof Your Basement Before You Finish the Space

Thinking about finishing your basement? It's best to address any water or moisture problems before construction begins. Legacy Supportworks installs basement waterproofing in the Texas Panhandle and Northwest Texas to help establish a dry, protected space before you invest in new walls, flooring, furniture and other finishing touches.

Signs Your Basement May Not Be Ready to Finish

An unfinished basement can create valuable living space in your home, but finishing it is a substantial investment. Before construction begins, keep an eye out for signs of water or moisture problems that should be addressed first. Dampness, stains, leaks, mold, efflorescence and foundation cracks can all call for a closer look before they're concealed behind finished walls and floors.

Why Waterproof Before You Finish Your Basement

Addressing existing problems and potential sources of water intrusion before the work begins helps protect your finished space while making waterproofing work easier and less disruptive to complete. A dry, protected space is the foundation of a successful basement finishing project. Water and excess moisture can damage the drywall, flooring, insulation, trim and furnishings you've invested in.

  • Finishing First Can Cost You More Later

    Waterproofing a finished basement may mean removing drywall, flooring or other materials to get to problem areas and rebuilding those finishes afterward. Resolving water and moisture concerns before finishing can help you avoid those added costs and disruptions.

    Basement waterproofing may involve a mix of drainage, sump pumps, vapor barriers, crack repair, dehumidification, mold control and other solutions. After an inspection, Legacy Supportworks can recommend the right solutions for your basement and explain how they can work together to handle water and moisture.

3 Steps to Take Before Finishing Your Basement

  • 1. Inspect the Unfinished Space

    Check the basement for existing water and moisture concerns while the foundation is still accessible.

  • 2. Address Waterproofing Needs

    Wrap up the recommended waterproofing or moisture-control work before walls and flooring are installed.

  • 3. Finish With Confidence

    Get started on your finishing project knowing you’ve taken steps to safeguard the materials and improvements going into the space.

Legacy Supportworks’ Basement Waterproofing Solutions

Every basement has different waterproofing needs. Depending on the source of water or moisture, the right approach may involve one solution or several working together. Legacy Supportworks can inspect your basement and recommend a waterproofing system that helps protect the space before you start finishing. Basement already finished? Not a problem. Many waterproofing solutions can be installed in finished spaces as well.

Things to Consider Before Finishing Your Basement

Know Your Basement’s History

Don’t judge by how the basement looks today. Past leaks, seepage, standing water or flooding can point to conditions that should be addressed before finishing.

Check Exterior Drainage

Verify gutters, downspouts and grading help move rainwater away from the foundation rather than letting it collect alongside the home.

Test Your Sump Pump

If your basement already has a sump pump, test it before finishing and have an aging or unreliable system evaluated. Consider whether backup protection is appropriate for your home.

Consider Sump Pump Backup Protection

If your finished basement depends on a sump pump for protection, consider whether a battery backup system is right for your home. Backup protection can help keep the system working during a power outage.

Plan for Future Access

Resist permanently covering equipment or components that may require inspection, maintenance or replacement. Your waterproofing and finishing plans should align.

Manage Humidity Year-Round

A basement can have excess humidity even without an active leak. Plan for ongoing humidity control to help protect finished materials and keep the space comfortable.

Complete Waterproofing Before Finishes Go In

If improvements are recommended, take care of them before drywall, flooring, insulation and trim make the foundation harder to reach.

Coordinate With Your Finishing Contractor

Check that your finishing plans work around the waterproofing system and allow required components to remain accessible.

Don't just take our word for it

See what our customers have to say about our work.

Legacy SupportWorks was referred to me by Bernie Sanders with Sir Speedy. When doors began to not close properly and there were noticeable gaps between the floor and molding, we knew it was time to get some foundation work done on our home. We shopped around and were pleased with the value and responsiveness of Legacy Support Works. I felt comfortable with them in my home, they delivered what they promised when they promised and left my home clean. From Tessa who made the initial contact, to the gentleman putting my carpet back in place, customer service was outstanding.

Mike P. | Amarillo, TX

When Karen H. saw some cracks on her wall, she knew something was wrong. She first called a local contractor and they told her that the cracks were being caused by the trees in her backyard. Karen wasn’t convinced by their explanation so she decided to get a second opinion and called Legacy Supportworks. In this video she talks about the experience she had with the company and why she was confident to hire them as the right company for the job. “What we got from Legacy Supportworks was not just a company that will be there for us through the whole process, but be there for us through any other problems that we have in the future”, says Karen.

Before & after photos

Check out before and after photos from some of our completed projects.

  • Stabilizing a Crawlspace in Pampa, TX

    This home had crawlspace beams that were cracking and lacked stabilization. 

    Years of shimming had only been a “band-aid” fix and this customer was looking for a permanent solution.

    Our crew installed steel beams and steel smartjacks on engineered fill.

    The result was a permanently stabilized floor!

  • Concrete Repair in Spearman, TX

    A customer reached out after seeing a video of concrete lifting using injection methods and wondered if it could work for their front porch. Their home, built in 1968, features a large concrete porch with a section that originally had a planter between it and the house. At some point, the planter was covered with concrete, which has since sunk about 4 inches. Both sections measure approximately 8×12. While the porch itself was fine, they wanted a solution to lift the concrete over the old planter rather than starting from scratch. Legacy inspected the situation and provided a tailored solution to restore their home.

  • Foundation Repair in Guymon, Oklahoma

    Just four years after adding a first porch for relaxation, a homeowner in Guymon, OK found himself facing a disheartening problem – his beloved porch had settled a shocking 2 feet into the ground, taking his dreams of peaceful rocking chair afternoons with it. As depicted in our before photo, this alarming sinkage rendered the space unusable. To lift and stabilize the sinking structure, we deployed our trusted Push Pier system, meticulously engineered to provide strength and elevation from deep below the surface. The transformation is apparent in the after photo, where the porch now stands level and secure, promising many future years of comfort and stability. At Legacy Supportworks, reviving your home’s foundation to ensure lifelong enjoyment and safety is not just our mission—it’s our commitment to you.

Frequently Asked Questions

How long does waterproofing take before I can start finishing? 2026-10-08T13:36:14-05:00

The timeline depends on which waterproofing solutions your basement needs and the scope of the installation. Some projects can be completed fairly quickly, while more extensive work may take longer. During your inspection, Legacy Supportworks can walk you through the recommended work and help you understand when it’s safe to move forward with your basement finishing project. 

Will waterproofing prevent mold in my finished basement? 2026-10-08T13:35:45-05:00

Basement waterproofing can help control water and excess moisture, two conditions that can contribute to mold growth. But no solution can guarantee that mold will never develop. Addressing leaks, seepage and humidity before finishing can help create a drier environment and limit moisture-related problems behind finished walls and floors. 

What does a basement waterproofing system include? 2026-10-08T13:35:15-05:00

It depends on your basement and where the water or moisture is coming from. A waterproofing system may combine an interior drainage system, sump pump, vapor barrier, foundation crack repair, dehumidifier, mold control or other solutions. Legacy Supportworks can inspect your basement and recommend the best combination for your home. 

How much does basement waterproofing cost in the Texas Panhandle and Northwest Texas? 2026-10-08T13:34:41-05:00

The cost to waterproof a basement in the Texas Panhandle and Northwest Texas depends on the source of the water, basement size, existing conditions and the solutions needed. A targeted crack repair differs significantly from a drainage and sump pump installation. Legacy Supportworks provides free inspections and estimates so homeowners can review the recommended solution and pricing before moving forward. 

Is it more expensive to waterproof a basement after it’s finished? 2026-10-08T13:34:03-05:00

Yes, waterproofing a finished basement can be costlier and more disruptive in some cases. Depending on the waterproofing work needed, contractors may have to remove drywall, flooring, trim or other finished materials to reach the foundation and install a solution. You may then have the added expense of restoring those finishes. Addressing waterproofing beforehand can help avoid these additional costs and disruptions. 

Do I really need to waterproof my basement before finishing it? 2026-10-08T13:32:43-05:00

You should resolve any existing water or moisture problems before finishing your basement, but not every basement needs the same waterproofing solutions. An inspection can identify leaks, drainage issues, high humidity, cracks or other concerns while the foundation walls and floor are still easy to reach.
