Common questions
What services is Mainmark listed for?
On this directory, Mainmark is categorised under Resin injection. Confirm the specifics with Mainmark directly, since a directory listing is a starting point for comparison, not a guarantee of current capability.
Is Mainmark licensed and insured?
This directory carries name, city and service focus only, not licensing or insurance verification. Ask Mainmark for their current licence and insurance details directly, and check them against your state's building regulator if you want independent confirmation.
Should I get a structural engineer's assessment before contacting Mainmark?
For anything beyond hairline cosmetic cracking, yes. A structural engineer independently diagnoses whether footings have moved and why, and specifies the repair; a contractor like Mainmark then prices and carries out that repair. Getting the engineer's report first means every quote you get, including from Mainmark, is priced against the same diagnosis.
How much should I expect a job like this to cost?
Underpinning and concrete repair are quote-driven work, typically $4,000 to $15,000 for common residential underpinning jobs, but method, soil and access swing the number a lot. Get a written quote from Mainmark or any contractor you compare, and check it against our cost guide.
