What our customers say about us…
BEWARE of companies that refuse to give quotes over the phone.
Companies that refuse to do so are often “flat rate” or “book pricing”. What does this mean for you? A technician will come out and give you an outrageous estimated price, and if you don’t agree to use them, they charge a hefty service fee.
We are so confident we will earn your business, we offer free estimates on new garage doors, and have no service charge!
