Straight Answers Before You Send Anything

What this site is, what it costs you and what happens after you press send.

  • It Costs You Nothing

    Sending an enquiry is free and puts you under no obligation. We are paid by the trade side, never by you, and no price on this site is ours to set.

  • Check Them Yourself

    Whoever contacts you has a public record: a Google Business Profile, Checkatrade, Trustpilot or the Federation of Master Builders. Look them up before you commit.

  • No Scores We Have Not Earned

    There is no star rating anywhere on this site, because we have none yet. When there are real reviews, they will appear with the source attached.

One Enquiry, The Right Trade On The Other End

Finding a builder in London is not hard. Finding one who does your particular job, at your size, on your street, and who is free when you need them, is the part that eats weeks.

This site shortens that. You describe the work once. The enquiry goes to a trade whose normal week looks like your project, and they contact you directly to price it. There is nothing to pay us and no obligation on you.

  • You describe the job once, not six times
  • Matched on trade, size and location
  • The trade quotes you directly
  • No charge and no obligation to you

Costed First

Quantity surveying is on this site as a service in its own right, because on a larger job it pays for itself.

Built Locally

Enquiries go to trades working on that type of property in that part of London, not to whoever is nearest.

Why Go Through Us First

What decides whether a building enquiry turns into a job that goes well happens long before anyone picks up a trowel.

  • The Enquiry Reaches The Right Trade

    A side return infill, an underpinning job and a bathroom refit need three different firms. Routing on the detail rather than the postcode alone is what makes the first conversation worth having.

  • Cost Gets Looked At Early

    Most budget failures are set at concept stage and only discovered on site. Quantity surveying is on this site as a service in its own right because on larger jobs it pays for itself.

  • You Know What Is In The Price

    Two quotes are only comparable when both list their exclusions. We say so plainly, and it is the single most useful question you can put to anyone who prices your job.

  • London Property Behaves Differently

    Clay that moves, trees with protection orders, leasehold flats, conservation areas and drainage nobody has mapped. Trades who work here already expect all of it.

The Work We Take Enquiries For

Twelve trades across surveying, structure and finishing. Pick the closest one and tell us the detail on the form.

Questions We Get Asked

What exactly does RCRO Building do?

We are a lead generation site. You tell us about the job you need doing and we put you in contact with a trade that carries out that work in your area. We do not carry out the work ourselves and we do not charge you for the introduction.

Which areas do you cover?

London and every town within 20 miles of it. The areas page lists them, and the quote form asks for your postcode so the enquiry reaches somebody who actually covers your street.

How quickly will somebody get back to me?

That depends on the trade and how busy they are, so we do not promise a time we cannot control. Giving a clear description of the job and a phone number in the form is what gets a faster, more useful response.

Does it cost anything to send an enquiry?

No. Sending the form costs you nothing and puts you under no obligation. Any price you are later given comes from the trade directly, and the arrangement you make is with them.

What should I put in the form?

What the job is, where the property is, and anything already decided such as drawings, a planning reference or a start date. The more specific you are, the better the match and the closer the first answer will be.

Can you help with commercial work as well as homes?

Yes. Quantity surveying, groundwork and refurbishment enquiries regularly come from landlords, developers and small commercial projects as well as homeowners.
