Working with Builders and Contractors: A Homeowner's Guide

Many homeowners approach builder selection as a price comparison exercise, choosing whoever quotes lowest. This approach frequently leads to disappointing results. The cheapest quote often comes from operators who underestimate work, use inferior materials, or plan to recover margin through variations. Experienced renovators know that choosing a builder is about finding the right match of skill, reliability, communication style, and value.

This guide covers the full process from finding candidates to final payment, helping you navigate each stage with confidence.

Finding the Right Builder

The search for a good builder should start well before you need one. Good tradespeople are busy, often booked months ahead. Starting early gives you time to research thoroughly rather than rushing into a decision because your project timeline demands it.

Word of Mouth

Personal recommendations remain the most reliable way to find quality tradespeople. Ask friends, family, neighbours, and colleagues about their renovation experiences. People are generally honest about both positive and negative experiences, giving you real insight into what working with a particular builder is actually like.

When you receive a recommendation, ask specific questions. Was the work completed on time and on budget? How did the builder handle unexpected problems? Was communication clear throughout? Would they hire them again? The answers reveal more than any advertising.

Online Research

Online reviews provide additional perspective, though they require careful interpretation. A few negative reviews among many positive ones may reflect unrealistic client expectations rather than poor work. Consistently negative themes across multiple reviews warrant caution. Look for specifics about quality, communication, and problem resolution rather than just star ratings.

Getting and Comparing Quotes

Request quotes from at least three builders for any significant project. Provide identical information to each, including plans, specifications, and any specific requirements. This allows meaningful comparison rather than comparing quotes for different scopes.

What a Good Quote Includes

A professional quote should be detailed and specific. It should itemise labour and materials separately, specify exactly what is included and excluded, provide an estimated timeline, and state payment terms. Vague quotes with single lump-sum figures make comparison difficult and create scope for disputes later.

Pay attention to what is explicitly excluded. Common exclusions include consent fees, engineering, scaffolding, and removing unexpected problems like asbestos or rot. Understanding exclusions helps you budget for the true total cost rather than the headline quote figure.

Evaluating Beyond Price

The lowest quote is not automatically the best choice. Consider the builder's experience with similar projects, their communication during the quoting process, references from previous clients, and your overall impression of their professionalism. A slightly higher quote from a reliable builder often delivers better value than a cheap quote from an unknown quantity.

Contracts and Agreements

For any significant project, a written contract protects both parties. The contract should specify the work to be done, the price, payment terms, timeline, and how variations and disputes will be handled. Verbal agreements are legally binding but difficult to enforce when memories differ.

Standard Form Contracts

Several standard form contracts are available for residential building work in New Zealand. Registered Master Builders, Certified Builders, and other industry bodies provide templates that cover essential terms fairly. These contracts are well-tested and provide reasonable protection for homeowners without requiring expensive legal drafting.

Read any contract thoroughly before signing. Understand your obligations as well as the builder's. Ask about anything unclear rather than assuming you know what terms mean. A reputable builder will welcome questions and explain contract provisions clearly.

Deposits and Progress Payments

Builders typically require a deposit before commencing work and progress payments at defined stages. This is standard practice, but the amounts and timing should be reasonable and tied to work actually completed.

Deposit Guidelines

A typical deposit is 10 to 20 percent of the contract value. Larger deposits may be reasonable for projects requiring significant material purchases upfront, but deposits exceeding 30 percent warrant caution. Avoid paying large sums before any work has been completed.

Progress payments should correspond to completed stages of work. Common payment milestones include completion of foundations, framing, roofing and cladding, interior lining, and final completion. Each payment should reflect the value of work completed to that point, not simply be an equal fraction of the total.

Retentions

Retaining a portion of the contract price until defects are remedied is standard practice in commercial building but less common in residential work. Holding back 5 to 10 percent until you are satisfied that defects have been addressed provides incentive for the builder to complete all work to an acceptable standard.

Managing the Relationship

Good communication throughout the project prevents misunderstandings and catches problems early. Establish expectations about communication frequency and methods at the start. Regular site meetings or updates keep you informed without requiring constant presence.

Documenting Decisions

Keep written records of all decisions, particularly any changes from the original scope. Email is ideal as it creates a date-stamped record. When discussing changes on site, follow up with a written summary confirming what was agreed. These records protect you if disputes arise later.

For kitchen and bathroom renovations and other complex projects, create a decision schedule with your builder. Know what choices you need to make and when. This prevents rush decisions that lead to regret and keeps the project moving without delays caused by waiting for your input.

When Things Go Wrong

Despite best efforts, problems sometimes arise. Work quality disappoints, timelines blow out, or communication breaks down. How you handle these situations determines whether they become minor bumps or major disputes.

Addressing Concerns Early

Raise concerns as soon as they arise rather than letting frustration build. A calm, specific conversation about your concerns is more likely to produce resolution than waiting until you are angry. Focus on the issue rather than personal criticism. Most builders want satisfied clients and will work to address legitimate concerns.

Formal Dispute Resolution

If informal discussion fails, most contracts include dispute resolution provisions. These typically involve mediation before arbitration or court action. Mediation brings a neutral third party to help reach agreement. It is faster and cheaper than legal proceedings and often produces satisfactory outcomes.

For disputes with LBPs, you can complain to the Building Practitioners Board if you believe the work does not meet building code requirements or the builder has acted incompetently or negligently. For disputes about contract performance, the Disputes Tribunal handles claims up to $30,000 without needing a lawyer.

Final Inspection and Payment

Before making final payment, conduct a thorough inspection of completed work. Create a defects list noting anything requiring correction or completion. Walk through systematically, checking that all agreed work has been done to an acceptable standard. Test fixtures and fittings to ensure they work correctly.

Provide your defects list to the builder in writing and agree on a timeline for remediation. Final payment should occur after defects are addressed. Withholding a reasonable amount pending defect rectification is appropriate; withholding payment unreasonably is not.

Retain all documentation from the project including the contract, invoices, warranties, and compliance certificates. This documentation proves valuable for insurance purposes, future maintenance, and eventual sale of the property.
