They acted very professionally, did careful work, and the finished chimney looks better than the original.

Custom Fabrication FAQ

Q: Can you match the colour of the windowsills on my house?

A: There are two things that affect the colour of custom concrete products. The pigment used, and the colour of the aggregate. We can usually match at least one, if not both.

Q: How do you make the products

A: The ingredients are carefully measured and mixed, then poured into wooden forms. Different processes are applied depending on required finishes. We then allow a proper cure time of 21-28 days before delivering or installing the product.

Q. Why would I get custom concrete sills or other products?

A: Almost all of our products are produced to match existing structures. Most houses from 1900-1950 have custom concrete sills and the companies that made them no longer exist. We are able to create reasonably accurate historical reproductions to keep the character of the structure intact.

Estimates FAQ

Q: How do you price your estimates?
A: Estimate prices are based on either square footage/number of units or by number of workers x number of days. Company costs such as trucks, gas, storage, insurance, advertising, offices etc. are added to the estimates as a fixed percentage.

Q. Can I get a better deal by getting more work done?
A. Yes. Square footage and per unit prices are lower with higher volumes. Doing 2 jobs at the same time (chimney and parging for example) will often lower the overall price.

Q. Who does your estimates?
A. We have one experienced estimator who does 90% of all our estimates. This allow us to focus on proper customer service and consistency.

Q. How soon can I get an estimator to come by?
A. Usually between 1-5 days from when you call in depending on our call volume and the area.
