Blue Umbrella Waterproofing Description

Blue Umbrella Waterproofing is a family‑owned, New Jersey-based waterproofing and foundation repair contractor that specializes in protecting homes and businesses from basement flooding, crawl space moisture, and structural foundation damage.

Operating across central and northern New Jersey and the Jersey Shore from its Cranford headquarters, the company provides on-site free inspections and tailored solutions backed by lifetime warranties and a New Jersey HIC license.

Their core services include interior and exterior basement waterproofing using interior French drain systems, concrete trench drains, and professionally installed sump pump systems with battery backups to ensure continuous protection during storms or power outages.

For crawl spaces they offer full encapsulation, vapor barriers, specialty crawl space sumps, and dehumidifier installations to control humidity, prevent mold, and improve indoor air quality.

On the foundation side, the company addresses wall cracks, bowing or leaning walls, and settling foundations with epoxy crack injections, steel I‑beam installations, and carbon fiber strap reinforcement systems (Fortress Stabilization Systems) for long‑term structural stabilization.

They emphasize using high‑quality, industry‑recognized materials and provide maintenance plans for sump pumps, dehumidifiers, and drainage systems.

Review 1
We used Blue Umbrella to update our basement waterproofing following major plumbing updates to our sewer & water main lines. Our initial bid & inspection were provided by Marvin, who I cannot say enough positive things about. He is such a great person — extremely knowledgeable, authentic and honest. He also took the time to help me make sense of other bids we had gotten for the waterproofing job and to understand what solutions made the most sense for our basement. In the end, we decided to go with Blue Umbrella. Not only did they offer a far more competitive price point for the overall job (which included replacing a poorly installed sump pump that our plumber put in & a brand new French drain installation) — but, also included in our bid were the leader line installation, moisture barrier installation and a new dehumidifier installation. Our project managers (Wilson & Diego) were extremely knowledgeable & led a great crew of workers, who were all highly efficient, hard working & courteous. Our job took 2 days, and both days the crew left our job site immaculate. They even took the time to backfill the trench left behind by the plumbing company, because the dirt had settled quite a bit, and this, without even being asked to do so. This entire team went above & beyond for our project, from owner (Steve), to supervisor (Marvin), to Wilson and the entire work crew. These guys were all wonderful! Best of all, their work comes with a Lifetime Warranty certificate, which can be transferred should we ever sell this home. I highly recommend Blue Umbrella. You won’t be disappointed with their professionalism, their authenticity, or their superior work. Thanks so much!

I recently had my basement waterproofed by Blue Umbrella, and I couldn’t be more happy! From start to finish, their team was professional, punctual, and thorough. They took the time to explain the entire process and addressed all my concerns. The work was completed efficiently, and the results have been fantastic – no more leaks or dampness!
