Hiring Your Newmarket Basement Contractor: 20 Questions To Ask First

Ask better questions, hire better. The quickest way to screen a basement contractor is to confirm three things: basement‑specific experience, a clean plan for permits and inspections, and a transparent contract and schedule. Newmarket and surrounding cities require building permits for most construction and major renovations, and plans are reviewed for Ontario Building Code and zoning before work starts. That means the right contractor can show how approvals and inspections fit your calendar from day one.

How To Use This List In 10 Minutes

Print the questions and bring them to your discovery call and walkthrough. Score each answer green/yellow/red. Green means proof is available now. Yellow means “possible, but needs documents.” Red means risk. Keep notes so you can compare contractors on equal terms rather than gut feeling.

Ask for documents as you go: WSIB clearance and liability certificates, a sample permit set, a milestone schedule with inspection holds, and a draft contract. You’re looking for evidence, not eloquence. If answers are confident but documents lag, pause before you sign. The City’s building pages confirm permits are required for most construction, and inspections must be scheduled and passed at defined stages.

Bottom line: use this list to test both competence and process. Good contractors welcome structure. It makes the job smoother for everyone.

The 20 Questions To Ask Your Basement Contractor

1) Can You Show Three Recent GTA Basements Like Mine?

You want similar scope, finish level, and constraints—completed within the last 18–24 months. Ask for reference contacts and what inspections each project passed. Recent, comparable work beats generic galleries.

2) Who Handles Permits And Inspections, And What’s The Sequence?

A strong answer: “We prepare drawings, submit the permit, track review comments, and book framing, insulation, and final inspections on a shared schedule.” Newmarket confirms plans are reviewed for Code and zoning, and inspections must be called at specific stages. Expect to see this mapped on a calendar.

3) Will A Licensed Electrical Contracting Business Do The Electrical?

Electrical is regulated. Ask for the electrical contractor’s legal business name and licence number, plus proof of inspections tied to your job. Ontario regulation states no one may operate an electrical contracting business without an electrical contractor licence. That’s non‑negotiable for safety and compliance.

4) Can I See Your WSIB Clearance And Liability Insurance?

Request certificates dated within 30 days. Confirm policy limits and that the insured name matches the entity on your contract. If the paperwork is “in progress,” wait until it’s in hand.

5) What’s Your Plan For Code‑Compliant Egress?

Bedrooms need a safe, measured escape route. Listen for clear window or door sizing logic, window‑well drainage, and how grading affects the path to grade. Ask to see examples that passed inspection on the first try.

6) How Will You Solve Headroom Constraints?

Basements lose height to ducts and beams. Good contractors re‑route or compact services and, when needed, coordinate underpinning. Ask to see section drawings and photos that match your layout.

7) How Do You Manage Moisture Below Grade?

Expect a plan for subfloor systems, vapour control, and drainage at penetrations. Ask how they protect finishes if seasonal moisture appears and what monitoring they recommend post‑build.

8) What’s The Ventilation And IAQ Plan?

Look for balanced supply and return, correctly vented baths and dryer runs, and fresh‑air strategy appropriate to the layout. Poor air movement leads to odours, condensation, and comfort issues.

9) How Will You Control Sound Between Floors And Rooms?

Listen for assemblies using mineral wool, resilient channels, sealed penetrations, and solid‑core doors where needed. Ask which details they’ve found most effective in media rooms and suites.

10) What’s Included Versus Excluded In The Quote?

A clean estimate lists allowances (fixtures, flooring, tile), calls out exclusions (appliances, window coverings), and sets unit rates for predictable extras. If numbers are vague, expect price creep.

11) What Is Your Payment Schedule And Holdback Policy?

Draws should be tied to milestones, not calendar dates. Clarify statutory holdback and lien‑release steps. Ask for a sample invoice trail from a recent project to see how it flows.

12) Can I See A Milestone Build Schedule With Inspection Holds?

Permits and inspections shape the calendar. Ask for a simple Gantt with permit issue, rough‑in, insulation, and final inspections, plus float for corrections. Newmarket outlines when to call and what must be visible at inspection. City of Newmarket

13) What’s Your Change‑Order Process?

Require written change orders with scope, price, and time impact before work proceeds. Verbal approvals are how budgets go sideways. Ask to see a blank CO form.

14) Who Is The Daily Site Lead And How Do We Communicate?

You want a named supervisor, daily check‑ins, and a clear escalation path. Confirm response times and how they handle decisions if you’re unavailable during the day.

15) How Do You Protect Lived‑In Areas And Keep Things Clean?

Expect dust control, floor protection, waste management, and safe access routes. Ask about negative air machines and how they separate work zones from family space.

16) How Do You Handle Lead Times And Material Substitutions?

Good teams pre‑order long‑lead items and present pre‑approved alternates for risk items. That keeps inspections moving and avoids gaps in the critical path.

17) Can You Walk Me Through A Recent Inspection Punch List?

Look for small items closed quickly, no life‑safety misses, and documentation attached to the permit record. Newmarket allows you to request inspection status reports for issued permits, which your contractor should provide on request.

18) What Warranty Do You Offer And How Fast Do You Respond?

Get written terms for labour and materials and ask for typical response windows. Ask past clients how warranty service went in practice.

19) What’s Your Process For Design Selections And Approvals?

Selections should be tracked with deadlines that align to the build schedule. Late decisions cause idle days and rework. Ask to see a selections tracker from a recent project.

20) What Should I Do Now To Avoid Delays Later?

Good contractors give you a homeowner checklist: early decisions, pre‑ordering, and any city‑specific items for your address. That preparation reduces stress once trades are on site. Newmarket’s guidance on permits and inspections sets expectations for timing and visibility; align your calendar accordingly.

Red Flags: When To Pause Or Walk Away

Watch for permit avoidance. If someone suggests “skipping permits to save time,” stop. Newmarket lists penalties and delays for working without a permit, including extra fees and having to undo work. That costs more than doing it right the first time.

Be wary of vague allowances and long exclusion lists. If lighting, flooring, or tile budgets are unrealistically low, you’ll pay extras to reach your desired finish. Also be cautious of very low bids paired with aggressive timelines. When prices ignore inspections and lead times, schedules slip and quality suffers.

Finally, demand a named site lead and a change‑order process. Projects stall when no one is accountable and changes are handled verbally. Clear roles and written decisions keep momentum.
