How to Choose a Bathroom Remodeling Contractor in South Jersey

A bathroom is the smallest room most people remodel and the easiest one to get wrong. The work that decides whether it lasts — drain slopes, shower valves, waterproofing, ventilation — is buried behind tile before you ever see it. When it's done poorly, the failure shows up months later as a stained ceiling or a soft floor, not on the day the job wraps up.

That makes choosing the contractor the most important decision in the project. Here's what to check before you sign, based on more than 30 years of remodeling bathrooms across Gloucester, Camden, and Burlington County.

1. Confirm New Jersey Registration and Insurance

Anyone selling or performing home improvement work in New Jersey must be registered as a Home Improvement Contractor (HIC) with the NJ Division of Consumer Affairs, and must carry commercial general liability insurance. The registration number has to appear on the contractor's estimates, contracts, and advertising.

Don't just take the number on faith — look it up with the NJ Division of Consumer Affairs license verification and ask for a current certificate of insurance. For reference, KRidge Construction's registration is NJ HIC #13VH03284800.

2. Ask Who Is Doing the Plumbing

This is the question most homeowners skip. In New Jersey, plumbing work has to be performed under a licensed master plumber. Many bathroom remodelers aren't plumbers themselves, so they bring one in as a subcontractor — which means the person responsible for your drains and valves may not be the person you hired.

Ask for the plumber's name and license number, and whether they're on staff. KRidge has an NJ Master Plumber (License #6343) on the crew, so rough-in, valve, and drain work is done and inspected by the same team from demo to final walkthrough.

3. Ask How They Waterproof the Shower

Grout and tile are not waterproof. What keeps water out of your walls and subfloor is the membrane or waterproofing system behind them. A good contractor should be able to tell you exactly which system they use, how they handle the shower pan and niches, and whether they flood-test the pan before tile goes down.

If the answer is vague, ask to see photos of their in-progress work — not just finished bathrooms. What a contractor is willing to show you before the tile goes up tells you a lot.

4. Know Who Pulls the Permits

Most full bathroom remodels need permits under the New Jersey Uniform Construction Code, pulled through your town's construction office. The contractor should handle the applications and schedule the rough and final inspections. Permits protect you: inspections catch problems while walls are still open, and unpermitted work can surface later when you sell the house.

5. Get Everything in Writing

New Jersey law requires home improvement contracts over $500 to be in writing and signed by both parties. At a minimum, the contract should include:

• The contractor's legal name, business address, and registration number
• A description of the work and the materials to be used
• The total price, plus how and when payments are due
• Start and completion dates
• Your right to cancel within three business days of signing

Rules change, so confirm current requirements with the Division of Consumer Affairs — and be wary of any contractor who wants to start on a handshake.

6. Compare Quotes Line by Line

Bathroom quotes vary widely, usually because they include different things. Before comparing prices, check whether each quote covers demolition and disposal, subfloor or framing repair if rot is found, the waterproofing system, ventilation, and permits. Look closely at allowances for tile, vanities, and fixtures: a low allowance makes a quote look cheaper until you actually choose your finishes.

Red Flags to Watch For

• No HIC registration number on the estimate or contract
• Cash-only payment, or a large deposit before any work or materials are scheduled
• Pressure to sign the same day or to skip permits “to save money”
• No licensed plumber named for a job that moves or replaces plumbing
• Only finished-project photos, with no one willing to explain what goes behind the tile
• No references from recent bathroom projects
