“

Manjeet & his crew provided Basement remodeling services at our residence. He & his crew did provide quality work at competitive rates, however I am compelled to take One star as MJ ONTARIO CONSTRUCTION didn’t abide by my request to use the paint I asked for. Another Star for removing the Vinyl flooring boxes without our permission. Otherwise it all went well.
