03Free consultation

Walk the site with us before you spend a cent.

An experienced estimator visits, measures, opens up what can be opened, and sends you a written summary with a realistic budget range within five working days.

04How a build runs

Six steps, no surprises.

The same process on a $60K bathroom and a $5M office block. Only the drawings get bigger.

  1. 01

    Walk the site

    A senior estimator visits, measures, photographs and asks what you actually want. Free, and no obligation.

  2. 02

    Survey and scope

    We open up what can be opened, check structure and services, and write a scope you can read without a glossary.

  3. 03

    Fixed quote

    A line-by-line price with allowances marked clearly. You know what is fixed and what is a choice.

  4. 04

    Permits and planning

    We handle drawings, engineer sign-off and permit applications, and tell you plainly how long they will take.

  5. 05

    Build

    One site manager, weekly written updates, a photo log and a Friday walk-through with you.

  6. 06

06Clients

Straight talk from people we built for.

“They quoted a fixed price, finished a week early and left the site cleaner than they found it. I still cannot believe I am saying that about a builder.”
Rachel Ostrander
Harlow Ridge Residence
“Every Friday we got a written update with photos. There were no surprises and no arguments, just a kitchen that came out better than the drawings.”
Daniel Okafor
Millbrook Kitchen & Bath
“They hit an opening date that our landlord had already told us was impossible. The foreman knew every subcontractor by first name.”
