Business ProfileforNext Level Concrete Ltd

I hired next Level Concrete to build a concrete extension and a concrete walk alongside the attached garage at my property. The Contractor arrived on site on May 21 and removed my existing landscaping rock. They also spread about 1 m3 of the granular base building the subgrade 1 -3 in thick out of min. 6 in. On May 22 the worker arrived on-site and delivered the rebar. At that time it turned out we had a disagreement on the slope of the proposed concrete path. Because the concrete was to be placed on the existing common drainage swale I wanted to maintain the existing cross slope as per the neighborhood drainage plan, while the Contractor insisted on flattening the walk to 2% leaving 15 cm of setback from the property line. The Contractor accused me of violating specifications however he failed to provide any reference to the latter. He also could not back up his opinion on why I must build my concrete swale at a maximum 2-3%. My separated husband criticized the Contractor's work and the argument started. I requested husband to leave my property and apologized. The Contractor refused to continue work and hauled away the rebars and granular material delivered to complete the sub-base. The site has been abandoned since. After the incident, I researched the City of Edmonton Design&Construction Standards as well as the Residential Lot Grading Guideline. Based on this research I come up to the conclusion that both - my and the Contractor's opinions on design might be correct. On May 24th the Contractor emailed me advising me they won't return on-site even if I agree with their design because my husband was criticizing their work on May 23rd. The Contractor sent me an Invoice claiming that 1/3 of the total contract was complete, therefore he withheld my deposit of an equal amount. I disagreed with the evaluation of 1/3 because less than 10% of work has been complete and the site is abandoned. The contractor refused to return any money or complete the work.
