Basement Waterproofing Process Old Field

Here's Exactly How We Fix It

First, we inspect your basement to find where water is actually getting in. Not just where you see it, but where it starts. Foundation cracks, wall joints, floor seams – we map out every entry point.

Next, we choose the right approach for your specific situation. Sometimes that means exterior basement waterproofing to stop water before it reaches your foundation. Other times, interior basement waterproofing makes more sense. Often, it’s a combination that gives you complete protection.

Then we get to work with professional-grade basement sealers and proven waterproofing methods. We seal foundation cracks properly, apply basement wall sealer where needed, and install drainage systems that actually work. When we’re done, we test everything to make sure water stays where it belongs – outside.

How long does basement waterproofing take to complete?

Most basement waterproofing projects take 2-5 days depending on the size of your basement and the extent of work needed. Simple interior sealing might be done in a day or two, while comprehensive exterior waterproofing with drainage systems takes longer. We’ll give you a realistic timeline upfront and stick to it. Weather can affect exterior work, but we’ll keep you informed if delays happen. The key is doing it right the first time, not rushing through just to finish quickly.

What's the difference between interior and exterior basement waterproofing?

Exterior waterproofing stops water before it reaches your foundation walls – it’s prevention. Interior waterproofing manages water that’s already getting in – it’s control. Exterior work involves excavating around your foundation, sealing the outside walls, and installing proper drainage. Interior work focuses on sealers, crack repair, and drainage systems inside your basement. The best approach depends on your specific situation, budget, and how severe your water problems are. Sometimes you need both for complete protection.

Will waterproofing stop all basement moisture and humidity?

Proper waterproofing eliminates water seepage and major moisture problems, but some humidity is normal in any basement. We focus on stopping actual water infiltration – the stuff that causes real damage and creates mold conditions. After waterproofing, you might still want to run a dehumidifier during humid summer months, but you won’t have water coming through walls or pooling on floors. The musty smell disappears, and you can store things without worry about water damage.

How much does professional basement waterproofing cost?

Basement waterproofing costs vary widely based on your specific needs, basement size, and the extent of water problems. Simple crack sealing might cost a few hundred dollars, while comprehensive exterior waterproofing can run several thousand. We provide honest, detailed estimates after inspecting your basement. No surprise charges or pressure tactics – just clear pricing for the work that actually needs to be done. Remember, proper waterproofing is an investment that protects your home’s value and prevents much more expensive damage later.

What happens if water problems come back after waterproofing?

Quality waterproofing work should solve your water problems permanently when done correctly. We stand behind our work because we use proven methods and professional-grade materials. If you follow our recommendations for maintenance and something goes wrong with our workmanship, we’ll make it right. However, new foundation settling, major storms, or changes to your property’s drainage can create new issues that weren’t present during the original work. We’ll always be honest about what our work covers and what it doesn’t.

Can I waterproof my basement myself or should I hire professionals?

You can handle minor crack sealing or applying basement wall sealer for small moisture issues, but serious water problems need professional attention. DIY waterproofing often fails because it addresses symptoms rather than causes. We have the experience to find where water is actually entering, the right materials for permanent repairs, and the equipment for proper installation. If you’re dealing with ongoing water seepage, foundation cracks, or water after storms, professional waterproofing services will save you time, money, and frustration in the long run.
