What should I ask a caulking company to know if they are good?

Before hiring a caulking company in Toronto or the GTA, ask the right questions to ensure you’re dealing with true professionals. Start by asking what type of exterior caulking materials they use — look for 100% silicone or high-performance sealants designed for Canadian weather. Ask if they remove old caulking completely or just apply new material over it. Request photos of previous jobs, especially on homes similar to yours. Ask if they use backer rod, which is crucial for proper joint depth. Confirm they are insured, WSIB-covered, and provide a written warranty. Ask about their experience with winter caulking and cold-weather installation techniques. A reputable GTA caulking contractor will explain their process clearly, offer transparent pricing, and gladly answer all your questions. These questions help you identify high-quality professionals and avoid low-skilled installers.
