What to check before hiring a general contractor in St. John's

Five things to confirm with any firm, on this list or not, before you sign. The rules below are Newfoundland and Labrador's and St. John's's.

  1. Registration with WorkplaceNL

    Ask the firm for a clearance letter from WorkplaceNL, which confirms it is registered for workers' compensation and its account is in good standing. WorkplaceNL issues clearance through its online service, so a firm in good standing can produce one.

  2. Liability insurance

    Ask for a certificate of insurance that names the firm and shows commercial general liability coverage in force for the dates of your job, and check that the subcontractors it brings in are covered too.

  3. The building permit from St. John's

    Building permits for homes in St. John's come from the City of St. John's, and structural work, additions, new plumbing and electrical work and basement finishing usually need one. Agree in writing who applies for the permit and books the inspections.

  4. A written contract

    Get the scope of work, the payment schedule tied to stages of the work, start and finish dates, how changes are agreed and priced, and who handles permits and cleanup, all in one signed contract before any work starts.

  5. The warranty

    For a new house: ask whether the house will be enrolled in a third-party new home warranty, such as Atlantic Home Warranty, and what that warranty covers and for how long. For renovation work, get the firm's own workmanship warranty in writing.

General contractors in St. John's: common questions

What does a general contractor do on a home project?

A general contractor runs the job from start to finish: pricing it, booking and supervising the trades, ordering materials, arranging inspections and keeping the schedule. You deal with one firm instead of hiring the framer, plumber, electrician and drywaller yourself.

Do I need a building permit for a renovation?

Usually, for anything structural, for new plumbing or electrical work, and for most basement finishing, additions and decks. Your municipality sets the rules and issues the permit. Many general contractors apply for it as part of the job, so agree who is responsible before you sign.

What should a renovation contract include?

A written scope of work, the price and how changes will be priced, a payment schedule tied to stages of the work, start and finish dates, who pulls the permits, and the warranty on workmanship. Pay as stages are completed rather than most of the price up front.

Should I hire a general contractor or manage the trades myself?

Managing the trades yourself means booking, ordering and supervising each one, arranging the inspections and absorbing the delay when one trade holds up the next. A general contractor does that work and answers for the result. Running it yourself suits small jobs that need one or two trades.

How do I check that a contractor in St. John's is registered with WorkplaceNL?

Ask the firm for a clearance letter from WorkplaceNL. WorkplaceNL issues clearance through its online service, so a firm in good standing can produce one.

Who issues building permits in St. John's?

Building permits for homes in St. John's come from the City of St. John's. For general contracting, structural work, additions, new plumbing and electrical work and basement finishing usually need one. Many firms apply for the permit as part of the job, so agree who does it before you sign.
