They perform the work properly, provide great service, and are recommended
I used this company to waterproof our rental property’s basement over 2 years ago. The installation crew did a wonderful job as I have not encountered any issues regarding basement carpet being drenched. The sump pump they installed is also great as it is still working. I still use the company for annual maintenance and the technician I have dealt with have all been wonderful. They perform the work properly, provide great service, and recommendation. The best part I have found about this company is an exceptional customer service from everyone I have encountered with so far.

The repair looks excellent, and they left everything clean and tidy
I had Wizard Crack Repair fix a crack in my basement wall, and install a sump pump. I couldn’t be happier with the results. They were professional, punctual, and took the time to explain exactly what they were doing. The repair looks excellent, and they left everything clean and tidy when they were done.

Tailoring the fix to the unique layout of your property is crucial for lasting dryness. LEVEL IT stands out by providing thorough structural and moisture evaluations for both residential and commercial buildings across the region.
They inspect every angle of your water trouble to design a tailored system instead of pushing generic fixes.
We had a chat with one of their project specialists about low-disruption drainage options for finished floors, and their deep knowledge of soil mechanics was obvious.
Their AquaShield® perimeter system manages seepage over footings and across slabs without requiring heavy interior trenching. On top of that, all their waterproofing and structural services carry solid guarantees.
However, their primary expertise focuses on interior water management and drainage rather than complete exterior excavation and membrane wraps.
Did the job to a very high standard
Had a leak in my basement, Mariano was highly professional and spent a good 1 hour assessing and taking me through the diagnosis. Christian undertook the work within 2 weeks and was extremely knowledgeable and did the job to a very high standard. Highly recommend Level IT for any foundational leaks or issue.

They’re known for tackling groundwater problems by combining interior drainage trenches and sump pumps with foundation wall repairs and even full wall replacements when needed.
Their team leads are well-trained in sump pump setups and Drytech waterproofing, so you’re getting specialized help. We especially love that every job comes with a 10-year warranty.
While they do offer free estimates, it’s good to know this doesn’t apply to homes for sale or those booked through a real estate agent.
Most importantly, their focus is on keeping your structure sound; they don’t handle basement remodelling after the waterproofing is done.
