How do I switch internet providers in Castle Rock?
Compare plans on this page, confirm your preferred provider serves your exact address, then schedule the new install before cancelling the old service. Availability is block-level, so re-check the exact address even for providers listed across the rest of the city. Next, check whether your current contract carries an early-termination fee and note your existing billing date so you can time the change without paying for two services at once. Keeping the old line live until the replacement is installed and tested — an overlap of a day or two — protects you from an internet gap for work, school, or streaming. Ask your chosen provider whether self-install is offered at your address. Finally, return any leased equipment promptly to avoid unreturned-hardware charges, and keep your confirmation numbers until the final bill clears.
