The way a renovation should feel
One point of contact from quote to handover
The person who measures your home is the person who runs your project. You never have to chase answers between trades.
Transparent, itemised pricing
Every quote breaks the work down line by line, with allowances and exclusions written out. Changes are agreed in writing before they happen.
Licensed trades and vetted subcontractors
Electrical, plumbing and gas work is done by appropriately licensed trades. Every specialist on site is someone we work with regularly and hold to our standards.
Permits, drawings and inspections handled
We prepare drawings, submit applications and book every inspection. You'll know where approvals stand without making a single call to the city.
Site kept clean and safe
Dust containment, floor protection and a daily tidy are standard. Sites are secured at the end of every working day.
Workmanship warranty
Every project is backed by a written workmanship warranty. If something we built needs attention, we come back and fix it.
