Exceptional craftsmanship and outstanding quality. Despite unexpected challenges like exposing rot, they adapted quickly and delivered within the original timeline. Special thanks to Ed in sales, owner Luis, and the entire team on-site.

A1 Professional came quickly to give me a quote for a large deck. Gave me a great price and started on time. They took care of permits and was here every day until they finished. They are the best I’ve ever worked with!!

Nicolas Kensington

Great design and build — new deck, clearing trees and a pathway to my lake. Quality exceeded expectations, completion time was impressive and the price was reasonable. Will use them again.

Frequently Asked Questions

What's a fair price for door installation?

It depends on door type and material, but you should expect a clear itemized number, not a vague range. A1 Pro provides exact pricing on the spot during a free estimate.

Does installation make a big mess inside the house?

Not with A1 Pro. Crews protect flooring and furniture near the work area and clean up before leaving, so disruption stays minimal.

Is it cheaper to repair an old door or replace it?

Repairs cost less upfront but often resurface within a year or two on older doors. Replacement costs more initially but comes with a warranty and stops the problem for good. A1 Pro can tell you which makes more sense for your home.

How soon can A1 Pro get started on a project?

Scheduling depends on the current workload, but most estimates lead to a start date within a few weeks. A1 Pro provides a specific timeline for your free estimate.
