Sigma Painting provides luxury residential painting across Toronto and the GTA for detailed interiors, custom homes, sprayed architectural millwork, cabinets, Farrow & Ball specifications, Venetian plaster, and limewash. A high-end result depends on documented preparation, the right coating system for each substrate, controlled application, occupied-home protection, and a clear inspection process. Compare painters using real project evidence and a written finish specification, not a luxury label alone.
The service should connect the room design, substrate, application method, and construction schedule. These are Sigma's primary high-end scopes.

The written scope is the quality-control document. It should make the important decisions visible before work starts.

These are published planning ranges, not site-unseen quotes. The GTA interior painting cost guide explains the assumptions and cost drivers in more detail.
| Scope | Planning range | Context |
|---|---|---|
| Large whole-home interior | $12,000-$25,000+ for a 3,500+ sq ft estate home | Published planning range for vaulted ceilings and detailed millwork. Final price depends on scope and condition. |
| Kitchen cabinet refinishing | $3,500-$8,000 for a full kitchen | Published planning range. Door count, substrate, grain filling, boxes, colour, and hardware change the quote. |
| Custom millwork spraying | Quoted from drawings or an on-site review | Surface area, profiles, substrate, masking, access, colour, sheen, and on-site versus off-site work drive cost. |
| Venetian plaster or limewash | Sample and substrate review required | Sigma has not published a fixed range for these systems, so this page does not invent one. |
Sigma focuses on Toronto's established luxury neighbourhoods, where detailed millwork, plaster walls, and designer specifications are the norm:
Yorkville, The Kingsway, North Toronto, Roncesvalles, the Annex, and surrounding neighbourhoods are served the same way. Individual neighbourhood pages are added only when there is enough unique project evidence to support them.
Toronto painting service areaAsk each shortlisted contractor for the same evidence. A neutral comparison is more useful than a collection of superlatives.
Sigma's current warranty terms vary by service and product. Review the written warranty details against the coating system in your quote.
Luxury painting is defined by scope control and finish standard, not by a label. Look for comparable projects, substrate-specific preparation, documented coating systems, fine-finish capability, protection procedures, design and trade coordination, and a clear closeout process.
Shortlist contractors who can show original work similar to your home and explain the preparation, products, application method, schedule, site protection, and warranty in writing. The contractor should be comfortable saying when spraying, brushing, or a specialty applicator is appropriate.
Yes. A well-planned occupied-home project can be phased room by room with contained work areas, protected circulation routes, low-odour product options, agreed daily cleanup, and cure-time rules for children, pets, and frequently used rooms.
It can be when a specific Farrow & Ball colour or finish is part of the design. The decision should account for substrate preparation, primer, room use, sheen, application technique, touch-up expectations, availability, and the designer specification.
Sigma publishes a planning range of $12,000-$25,000+ for a 3,500+ sq ft estate-home interior with vaulted ceilings and detailed millwork. That is not a universal rate. Surface condition, access, trim volume, spraying, products, occupancy, and specialty finishes can move the final quote materially.
Sigma serves Toronto and the wider GTA. King City and Richmond Hill are core project markets in the current content strategy, while Oakville and Burlington are priority growth markets. Larger or specialized projects may be scheduled elsewhere in the service area.
