Basement Waterproofing Process

Here's Exactly What We Do

First, we inspect your basement to identify exactly where water is entering and why. We check foundation walls, floor joints, cracks, and exterior drainage patterns.

Next, we explain what needs to happen – interior waterproofing, exterior basement waterproofing, or both. You’ll know the plan before we start any work.

Then we execute the solution using professional-grade materials. Interior systems include basement wall sealer application and drainage installation. Exterior work involves excavation, foundation treatment, and proper drainage setup. We handle foundation crack repair as needed and make sure everything is sealed properly.

Everything Your Basement Needs

You get comprehensive basement waterproofing that addresses your specific situation. Interior basement waterproofing includes drainage systems, sump pump installation, and basement sealing treatments that stop moisture from coming through walls and floors.

Exterior basement waterproofing involves excavating around your foundation, applying waterproof barriers, and installing proper drainage to redirect water away from your home. We also handle foundation crack repair and structural issues that could let water in.

Lawrence homes often need both approaches because of our soil conditions and weather patterns. We’ll tell you exactly what your basement needs and why, so you understand what you’re paying for and how it protects your home long-term.

Basement waterproofing costs vary based on your specific situation, but most Lawrence homeowners invest between $3,000-$8,000 for comprehensive solutions. Interior waterproofing typically costs less than exterior work, but many homes need both for complete protection. The size of your basement, extent of water damage, and required drainage work all affect pricing. We provide detailed estimates after inspecting your basement so you know exactly what you’re paying for and why each component is necessary.
Most Lawrence basements need both interior and exterior waterproofing for complete protection. Exterior waterproofing stops water before it reaches your foundation walls, while interior systems handle any moisture that does get through. If you’re dealing with active leaks during storms, interior waterproofing gives you immediate relief. Exterior work is more comprehensive but requires excavation. We’ll assess your specific water issues and recommend the most effective approach for your situation and budget.
Interior basement waterproofing typically takes 2-4 days depending on your basement size and the systems being installed. Exterior waterproofing takes longer – usually 5-7 days because of excavation and foundation work. Weather can affect exterior projects, so we plan accordingly. Most Lawrence homeowners can continue living in their homes during interior work. We’ll give you a realistic timeline during your estimate and keep you updated if anything changes during the project.
Professional basement waterproofing should eliminate your water problems when installed correctly with quality materials. However, no system lasts forever without maintenance. Interior drainage systems need occasional cleaning, and exterior waterproofing can be affected by settling or landscaping changes over time. We warranty our work and use materials designed for Long Island conditions. Most of our Lawrence customers never have water issues again, but we recommend periodic inspections to catch any potential problems early.
DIY basement sealing products might handle minor moisture issues, but serious water problems require professional waterproofing systems. Lawrence basements often have complex drainage challenges that need proper diagnosis and installation. Mistakes with interior drainage or exterior excavation can make water problems worse and cost more to fix later. Professional waterproofing also comes with warranties and insurance coverage. If you’re dealing with active leaks, standing water, or mold growth, professional installation protects your investment better than DIY approaches.
Spring through fall works best for exterior basement waterproofing because of excavation requirements and concrete curing needs. Interior waterproofing can be done year-round since it doesn’t depend on weather conditions. Many Lawrence homeowners schedule waterproofing in late spring or early summer before storm season hits. If you’re dealing with active water problems, don’t wait – interior solutions can provide immediate relief while you plan exterior work for better weather. Emergency repairs can be done any time of year when necessary.
