Request a Free Estimate from Ottawa’s Magnum Exteriors

At Magnum we believe in the one price estimate: the price to do the job properly. We estimate your exterior using only the best products available.

Our estimates come with our price guarantee. If during an estimate we make a mistake and underestimate the job or if we forget something that should be done that mistake is never passed on to the customer. At Magnum, we will never finish a job and then ask you for more money than your estimate.
