Should I get three quotes from basement contractors in Moncton and how do I compare bids that seem very different?

You should get a minimum of three quotes — and ideally four or five — for any basement renovation in Moncton, because pricing in the New Brunswick market varies 30 to 40 percent between contractors for identical scope. This is not a small difference. On a $35,000 basement finishing project, that spread means the gap between the lowest and highest bid could be $10,000 or more.

The reason bids vary so dramatically is that basement work is not standardized the way a roof replacement or window installation might be. Every contractor approaches moisture management, insulation, and layout differently, and the scope assumptions behind each quote can be wildly inconsistent. One contractor may include waterproofing as a line item while another assumes the basement is already dry. One may quote rigid foam board insulation while another quotes cheaper fiberglass batts (which, in Moncton's Maritime humidity, is a recipe for hidden mold behind the walls). These are not equivalent bids even if the bottom-line number looks similar.

To compare bids effectively, break each quote into its component parts and compare line by line. A proper basement renovation quote in Moncton should itemize the following separately: waterproofing or moisture management, insulation type and R-value, framing and drywall, electrical rough-in and fixtures, plumbing (if applicable), flooring including subfloor system, ceiling type, permit fees, and a clear description of what is included versus excluded. If a contractor hands you a single lump-sum number with no breakdown, ask for an itemized version — any reputable contractor will provide one.

Here is what to watch for when comparing. First, check the insulation specification. In Moncton, you want rigid foam board (minimum R-12.5, ideally R-20) or closed-cell spray foam against foundation walls — never fiberglass batts touching the concrete. Moncton's sandy and silty soils drain relatively well compared to Saint John's clay, but the Maritime humidity still drives condensation on cold foundation walls from October through April. A lower bid that uses fiberglass batts is not actually cheaper — it is a mold problem waiting to happen.

Second, check whether waterproofing is included or assumed. Many Moncton homes from the 1960s through 1980s have concrete block foundations with no exterior membrane. If the contractor's quote does not address moisture at all, either they are assuming you will handle it separately or they are planning to finish over a wet basement — both are red flags.

Third, verify permit costs and who pulls them. A legitimate contractor includes building, electrical, and plumbing permits in the quote and handles the inspection process. In Moncton, the city building inspection department processes permits within one to three weeks and fees run $75 to $300 depending on scope. A contractor who suggests skipping permits to save money is someone you should walk away from immediately.

Fourth, compare payment schedules. A reasonable structure is 10 to 15 percent deposit, progress payments at defined milestones (framing complete, rough-in inspection passed, drywall hung), and 10 to 15 percent holdback until final inspection and your walkthrough. Be cautious of any contractor asking for more than 25 percent upfront.

Finally, verify that each contractor carries general liability insurance and WorkSafeNB coverage — ask for certificates, not just verbal confirmation. New Brunswick Basements can help you connect with vetted local basement contractors through the New Brunswick Construction Network to make the quoting process easier.
