Posted on Marwan ETrustindex verifies that the original source of the review is Google. Spark Restoration delivered my projects in a timely and budget friendly fashion. We had a tight schedule and small budget for the repairs that needed to get done on a few buildings; and hence, Spark's leadership provided alternative solutions that cut down costs and didn't jeopardize quality. They went above an beyond and repairs few other items that weren't part of the scope at no additional cost. Highly recommend Spark as they are our go-to contractor for all sorts of work.Posted on alexa ortizTrustindex verifies that the original source of the review is Google. Spark Restoration did an excellent job repairing a long-standing water leak in my basement foundation wall. After years of failed fixes, they finally identified the real issue and stopped it for good using a professional crack injection and proper exterior waterproofing. The leak is completely gone. They were clean, reliable, and very knowledgeable. I highly recommend Spark Restoration for any foundation or basement repairs.Posted on Lionell JacksonTrustindex verifies that the original source of the review is Google.

Shan and his team recently sealed the foundation at our house. The water line and sewer pipe enter the house in the basement and we were experiencing leaking around both pipes. We had engaged a different company previously and their solution did not stop the leaking for more than a couple months. Shan was able to identify the mistakes that company had made and correct them. What I liked best about Shan was his responsiveness. He always answered calls and texts. He was forthcoming with pricing. His team was prompt and professional. I would definitely recommend Spark if you need foundation repairs.Posted on Shabana NazTrustindex verifies that the original source of the review is Google.

Frequently Asked Questions
Why is my basement wall leaking during a storm in NYC?
Water sheets down the basement wall and pools at the stairs. Slipping risk rises for tenants and workers. Spark Restoration Inc. isolates the wet zone and secures paths with active containment on-site. Delay drives mold and electrical contact. NYC corridor access stays open, but the source remains live.
What should I do if my basement floor is heaving or cracked before finishing?
A slab crack lifts and creates a sharp trip edge across the basement aisle. Tenants step over it, and the spike falls. Spark Restoration Inc. stabilizes the cracked panel and secures the crossing with immediate containment. Delay widens the break and shifts walls. NYC basement traffic keeps moving, but the structure stays unstable.
Why are basement ceiling joists sagging after framing a new room?
The ceiling joists bow, and the drywall line drops over the corridor. Fasteners pull, and debris can fall on pedestrians in the stair run. Spark Restoration Inc. arrests the sag and secures the work zone on-site. Delay spreads the load into the walls and pipes. NYC access constraints tighten, and inspections trigger.
What does a rusted steel lintel in a basement opening mean during a conversion?
Rust flakes and brick dust spill from the lintel pocket above a basement window. The opening shifts, and the brick panel loosens. Spark Restoration Inc. secures the opening and stabilizes the brick and lintel interface immediately. Delay accelerates corrosion and cracks spread. NYC sidewalk vibration transfers in, and the hazard escalates.
What should I do if a basement egress stair feels loose during a conversion?
A stair stringer flexes, and the tread edge lifts underfoot. A fall hazard forms at the basement exit path for tenants and crews. Spark Restoration Inc. stabilizes the stair assembly and secures the landing with active containment. Delay loosens anchors and shifts framing. NYC egress rules tighten fast, and the exit remains unsafe.
