Whether your driveway, patio or steps need a permit is the city's call, and Malden Inspectional Services is the office that handles building permits. That's why we check with the city before any work starts and help you get the paperwork in order. If your job does need a permit, the start date waits on it, so I bring it up at the estimate instead of the week of the pour. When you're comparing contractors, check two things. The state licenses construction supervisors through the Board of Building Regulations and Standards, and businesses set up in Malden file a business certificate with the City Clerk.
The price comes down to how big the slab is, how much old concrete has to come out, and how deep we dig to reach firm subgrade, the packed ground the slab sits on. Whether you want a plain finish or something decorative matters too. The schedule turns on the permit, the weather and curing, the stretch where concrete hardens and gains strength before you can use it. I'll give you your own figure when I come out, the same way I do for jobs from Malden down to Newton.
