7 Questions to Ask Before Hiring a Builder in Warlingham

PTA Building Services

Choosing a builder is about trust, not just price

Hiring a builder can feel daunting, especially if you have never managed building work before. You are not just choosing someone to do a job. You are inviting a team into your home, trusting them with your money, and relying on them to turn your plans into something your family will live with for years.

That is why the right questions matter.

Below are seven questions we believe every homeowner in Warlingham should ask before hiring a builder.

1. Have you completed similar projects to mine?

Not all builders do the same type of work.

Someone who mainly builds new homes may not be the best fit for a Victorian terrace renovation. Likewise, a team experienced in extensions may handle live family homes more smoothly than a contractor who mostly works on empty properties.

Ask:

Have you done similar extensions or renovations recently?
Do you have photos or case studies?
What challenges came up and how did you handle them?

This helps you judge real-world experience, not just sales talk.

2. What is included in your quote, and what is not?

This is one of the biggest causes of confusion.

A quote can look competitive, but if key items are missing, the final cost can rise quickly. You need clarity from the start.

Ask for a breakdown covering:

Labour
Materials
Waste removal
Structural work
Finishes
Decoration
Plumbing and electrical works
VAT

Also ask what is excluded so there are no assumptions on either side.

3. Who will manage the project day to day?

Sometimes the person who visits to quote is not the person you will see on site.

That is not necessarily a problem, but you should know:

Who your main contact is
Who supervises the trades
How often updates are given
How issues are raised and resolved

Good communication is one of the strongest signs of a professional building firm.

4. How do you handle changes during the build?

Changes happen on many projects. Sometimes they are necessary. Sometimes a client changes their mind after seeing the space.

The important thing is how the builder manages those changes.

Ask:

How are variations priced?
Will changes be confirmed in writing?
How do they affect the timeline?

A clear process prevents stress and misunderstandings.

5. Are you insured and compliant?

This may feel obvious, but it is still worth asking directly.

Check for:

Public liability insurance
Employer’s liability insurance (if relevant)
Qualifications or certifications for electrical and gas works
Experience working with building control and regulations

A professional builder should be comfortable answering these questions.

6. What does your timeline look like, and what could affect it?

Every homeowner wants a realistic timeline. A good builder will avoid making promises they cannot keep.

Ask:

When can you start?
How long is the project expected to take?
What could cause delays?
How will you keep me informed if the schedule changes?

This gives you a clearer picture of what to expect and helps you plan family life around the work.

7. Can I speak to recent clients?

References are valuable, especially recent ones.

When speaking to previous clients, ask:

Was the builder reliable?
Was communication clear?
Was the site kept safe and tidy?
Were costs handled transparently?
Would you use them again?

People often tell you more about the process than the final finish, and that is exactly what you need to know.
