Replacing a double-bowl sink
Compare the old hole with the proposed sink template and show the cabinet below. A larger sink may be feasible; a smaller sink can leave uncovered areas. Filling an old double-sink opening generally leaves a visible result and may be a poor alternative to replacement.
What to send from your Baulkham Hills property
Start with a wide kitchen photo and a close view of the proposed cut. Include the underside if safely accessible, existing measurements and the manufacturer’s installation drawing for a replacement appliance or sink. Tell us about any joins, cracks or previous repairs and describe parking, stairs or shared-building access.
Choose the right scope
Cooktop enlargement, a new sink opening, tap-hole drilling and overhang reduction have different requirements. Specify every change you want included, and identify which cut edges will remain visible. The written quote confirms the agreed cutting and finishing; licensed gas, electrical and plumbing work is arranged separately.
Booking in Hills District
Your exact address and access arrangements help us plan the visit. For an overhang reduction, measure from the cabinet face to the existing edge at both ends. Include brackets, corbels or waterfall panels in the photos. Their position can determine whether the desired finished line is practical.
Price and suitability
Standard cutting starts at $690 + GST per cut and tap-hole drilling at $350 + GST. Final pricing depends on the material, cut, finishing and access. Not every installation can be modified: vulnerable rails, poor support or unsuitable edges may call for another solution.

Questions, answered.
Can you fill the unused part of the sink hole invisibly?
No invisible result is promised. A replacement section or a different sink may be more suitable where the old opening cannot be covered.
Can you work on my existing engineered stone?
Only suitable permitted work is considered, subject to material identification and applicable requirements. Send the product details and proposed change for assessment.
