Here's How We Stop Water Problems

First, we inspect your basement to find exactly where water is getting in. Not just the obvious spots – we look for the hidden entry points that cause problems later.

Next, we explain what we found and give you options. Interior waterproofing, exterior waterproofing, or both. We tell you what each approach costs and why we recommend what we recommend.

Then we get to work. We seal cracks, install drainage systems, apply waterproof coatings, and make sure water has nowhere to go except away from your foundation. We clean up completely when we’re done.

You get a dry basement that stays dry, plus a warranty on our work so you know it’s going to last.

Complete Basement Waterproofing Solutions

We handle both interior and exterior basement waterproofing depending on what your situation needs. Interior solutions include basement wall sealers, drainage systems, and sump pump installation. Exterior waterproofing involves excavation, foundation sealing, and proper drainage installation.

For Kings Park homes, we often recommend a combination approach. The clay soil here holds water, and the seasonal freeze-thaw cycles create foundation movement that opens up new cracks. We account for these local conditions in every job.

Our waterproofing services include crack repair, foundation sealing, moisture barrier installation, and emergency water damage response. Everything is warrantied because we stand behind our work.

Basement waterproofing costs vary based on your specific situation, but most Kings Park homeowners invest between $3,000 and $8,000 for comprehensive interior waterproofing. Exterior waterproofing typically runs higher due to excavation requirements. The exact cost depends on your basement size, the extent of water problems, and which waterproofing methods work best for your foundation. We provide detailed estimates after inspecting your basement so you know exactly what you’re paying for and why.
Both interior and exterior waterproofing have their place, and the best choice depends on your specific water problems. Interior waterproofing is often more cost-effective and handles most basement moisture issues effectively. Exterior waterproofing provides maximum protection but requires excavation around your foundation. For many Kings Park homes, we recommend starting with interior solutions since they solve most water problems at a lower cost. If you have severe foundation issues or major water infiltration, exterior waterproofing might be necessary.
Professional basement waterproofing should last 10-15 years minimum, with many systems lasting much longer when properly installed. The lifespan depends on the waterproofing method used, your home’s foundation condition, and local soil conditions. High-quality basement sealers and properly installed drainage systems can protect your basement for decades. We warranty our waterproofing work because we use materials and methods designed for long-term protection, not quick fixes that fail after a few years.
Basic waterproofing like applying basement wall sealer to minor cracks is possible for handy homeowners, but comprehensive waterproofing requires professional expertise and equipment. Improper waterproofing can actually make water problems worse by trapping moisture in walls or creating new entry points. Professional waterproofing contractors know how to identify all water sources, select appropriate materials, and install systems that work together effectively. For significant water problems or valuable basement spaces, professional installation is worth the investment.
Waterproofing creates a complete barrier against water infiltration, while dampproofing only slows down moisture penetration. Most builder-applied foundation treatments are dampproofing, not true waterproofing, which is why many basements develop water problems years later. Waterproofing uses thicker materials, multiple layers, and comprehensive sealing methods to stop water completely. If you’re dealing with actual water seepage or flooding, you need waterproofing, not dampproofing. The investment difference is significant, but so is the protection level.
The best time for basement waterproofing is before you have major water problems, but most homeowners call us after they’ve already experienced flooding or seepage. Spring and fall are ideal for exterior waterproofing since weather conditions are more predictable. However, we handle emergency waterproofing year-round because water damage doesn’t wait for convenient timing. If you’re noticing early signs like musty odors, minor seepage, or white mineral deposits on walls, addressing these issues quickly prevents more expensive problems later.
