How to find the right builder for your project

The builder you choose will be in your home for weeks or months. They will see your family routine, make noise, create dust and make decisions that affect the value of your property. Choosing the right one is not just about price — it is about trust, communication and competence.

If you already know what you need, you can request a trade quote from Star Hawk Builders Merchant for building materials. You can also find your nearest Star Hawk branch or browse our case studies to see the kind of projects we supply.

Here is a practical process for finding a builder who will do the job properly, on time and on budget.

Step 1: Start with a clear scope of work

Before you contact builders, know what you want. You do not need architectural drawings for an initial conversation, but you do need:

• A brief description of the work (extension, loft conversion, renovation, etc.).
• The approximate size.
• Your intended start date.
• Your budget range.
• Any must-haves (bifold doors, underfloor heating, specific finishes).

The clearer your brief, the more accurate and comparable the quotes will be.

Step 2: Build a shortlist of three to five builders

Use multiple sources:

• Personal recommendations from friends, family or neighbours who have had similar work done.
• Trusted trade bodies such as the Federation of Master Builders (FMB), NHBC or TrustMark.
• Local builders merchants. Merchant staff know who buys quality materials, pays on time and has a good reputation.
• Online reviews on Checkatrade, Which? Trusted Traders or Google — but read them critically.

Avoid anyone who approaches you door-to-door, offers a "today only" price or claims to have leftover materials from another job.

Step 3: Check the basics before inviting them round

A quick phone or email screen will save you time:

• Are they available in your timeframe?
• Do they have experience with your type of project?
• Are they based locally?
• Can they provide references and insurance details?

If they are vague, slow to respond or pushy, cross them off the list.

Step 4: Invite the shortlist to site

A good builder will want to visit the property before quoting. This is your chance to assess them in person. Pay attention to:

• Do they listen? Or do they talk over you and dismiss your questions?
• Do they take measurements and notes? A builder who quotes from a brief email is guessing.
• Do they flag practical issues? Good builders point out access problems, drainage concerns or structural questions early.
• Are they professional? Punctuality, courtesy and a clean van are small but meaningful signals.

Step 5: Ask for references and follow them up

Request two or three recent references for similar projects. Then contact the homeowners and, if possible, visit the finished work. Ask:

• Did the builder start and finish on time?
• Did the final price match the quote?
• How did they handle problems?
• Was the site left tidy?
• Would you use them again?

If a builder cannot provide references, walk away.

Step 6: Verify insurance and credentials

Ask for copies of:

• Public liability insurance certificate.
• Employer's liability insurance certificate (if they have staff).
• Contractor's all-risk insurance for larger projects.
• Any trade body membership certificates.

Do not just look at the documents. Call the insurer or broker to confirm the policies are active and cover the type of work you need.

Step 7: Get three itemised written quotes

Verbal estimates are worthless. Insist on written quotes that include:

• A clear description of the work.
• Labour and materials separated where possible.
• Waste removal.
• VAT.
• Payment schedule.
• Start date and estimated completion date.
• What is excluded (e.g. kitchen units, tiles, decorating).

Comparing three quotes for the same scope will quickly show you the market rate and highlight any obvious outliers.

Step 8: Ask the awkward questions

Before you decide, ask each builder:

• Who will actually be on site day to day?
• Do you use subcontractors? If so, for what trades?
• How do you handle changes to the scope?
• What happens if you find unexpected problems?
• What warranty do you offer?
• Who orders and pays for materials?

The answers will tell you a lot about how organised and transparent they are.

Step 9: Check the contract carefully

A written contract should cover:

• The full scope of work.
• Total price and payment schedule.
• Start and completion dates.
• Procedure for changes and extras.
• Warranty terms.
• Dispute resolution.

For major projects, consider a JCT homeowner contract or have a solicitor review the document.

Step 10: Trust your instincts

If a builder is significantly cheaper than the others, pressures you to sign quickly or makes you feel uncomfortable, listen to that feeling. The right builder will communicate clearly, answer questions patiently and give you confidence.

What to do when every good builder is booked

In a busy market, even excellent builders can be fully booked for months. Do not panic and hire the first available trader. Instead:

• Ask your preferred builders whether they can recommend a trusted subcontractor or smaller associate firm.
• Widen your search radius slightly. A builder based ten miles away may still cover your area.
• Consider starting the project in autumn or winter when demand drops.
• Speak to your local builders merchant. They deal with dozens of trades every week and can often suggest reliable builders who are not advertising online.

A short delay to find the right person is far better than a long delay caused by poor workmanship.

How a builders merchant can help

Builders merchants see the same trades day after day. They know who orders quality materials, who returns faulty stock without argument and whose vans are loaded for tidy, well-run sites.

If you are struggling to find a shortlist, ask the trade counter staff at your local merchant for recommendations. A builder with a long-standing trade account is usually serious about their business. Star Hawk staff across the South East work with reputable local builders every day and are happy to point homeowners in the right direction.

Warning signs to avoid

• No fixed business address.
• Only a mobile number or generic email.
• Requests a large cash deposit.
• Refuses to put anything in writing.
• Cannot provide references or insurance.
• Quotes without visiting the site.
• Is vague about materials or subcontractors.

Final checklist

• Clear written brief prepared.
• Shortlist of three to five builders from trusted sources.
• Site visits completed.
• References checked and ideally visited.
• Insurance and credentials verified.
• Three itemised quotes received and compared.
• Key questions asked and answered.
• Written contract reviewed and signed.
• Payment schedule agreed with final retention.

Finding the right builder takes time, but it is the most important investment you will make in your project. A good builder will deliver quality work, manage problems calmly and leave your home better than they found it.
