Looking for a quote on a mudjacking job needed on my front steps. Look forward to hearing from someone. Kind regards, Steph

Vicinity of Bernice Cr in York

I have evidence of moisture wicking through the concrete block walls of the cold room in my basement. I would like a professional assessment of the extent of the problem and an estimate of the cost to assess it.

Vicinity of Church Street in York

Looking for estimate for ~9'x18' crawl space repair and encapsulation. White mold from small leak, possibly from adjacent sunroom foundation. Crawl space floor appears to be Styrofoam base with paperboard top layer. Accessed via basement bathroom storage closet.

Vicinity of Maplewood Avenue in York

I have a sloped driveway (concrete pad) that has a retaining wall on one side. Soil erosion under one of the pads has created a void, resulting in the pad sinking.

Thereza S. Vaughan Road

We would like to know why there is a difference between the membrane we were shown by Michael Beighton (salesperson) and the membrane that was installed. Also, what is the difference between the two. Lucio (foreman) did provide us with an explanation, but we would like clarification from Head Office.

We were under the impression that our Sump Pump would have a battery back up, but it does not have that feature.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your York home is both an eyesore and a safety hazard. It is also likely to get worse with time, but we can fix it for you!

Our experts use PolyLevel, a superior polyurethane foam to provide reliable concrete lifting & leveling solutions. Small holes are drilled in the concrete and the expansion of the foam lifts & levels the concrete. The majority of contractors you will call use mudjacking instead of foam. Mudjacking is heavier, requires larger holes in the concrete and does not last as long as PolyLevel.

If your home has cracked concrete steps, pool decks, patios, or other slabs, then NexusPro is the right solution. NexusPro repairs concrete cracks and joints and is ultra-durable, so it will withstand UV rays, extreme weather, and more.

After utilizing our expert concrete repair solutions, consider the powerful concrete sealant, SealantPro. SealantPro further protects your concrete by bonding with it to guard against oil, gasoline, liquids, and other debris. In just one coat, SealantPro extends the life of your concrete by 3 to 5 times overall.

Call us today to learn more about our proven concrete leveling, cracked concrete repair, and concrete sealing techniques.
