Sullivan Engineering | Waterproofing & Roofing in Totowa, NJ 07512

In Totowa, moisture-damaged insulation loses effectiveness and can lead to mold. Our moisture control installation creates a barrier to prevent water vapor from penetrating your attic, keeping insulation dry. This improves your home's energy efficiency, lowers bills, and protects against the structural damage common in our local climate.

Often, corroded flashing can be repaired without a full replacement. Our roof inspection will assess the extent of the corrosion and any resulting damage to shingles or decking. We typically perform targeted roof repairs to replace the flashing and seal surrounding areas, saving you money while solving the core issue common in Totowa homes.

Professional waterproofing installation is a proactive defense against basement leaks and foundation cracks, which are exacerbated by local soil conditions and rainfall. We apply high-grade membranes and drainage systems to direct water away from your foundation, preventing costly interior water damage and preserving your home's structural integrity for years to come.
