### Design and permits

We design your deck to match your home's architecture and your site, handle permit drawings, and file with the building department.

Concrete footings are dug and poured to frost depth; posts, beams, and joists create a level, sturdy structural frame.

### Decking and stairs

Deck boards are installed with proper spacing and fastening, and stairs are built to code with uniform rise and run.

Code-compliant railing is installed; wood decks are finished with a penetrating sealer or stain to protect against UV and moisture.

## Deck Building in Ajax: questions answered.

### How much does deck building cost in Ajax?

In Ajax, deck building typically runs based on scope and materials. Pro House Maintenance gives every Ajax homeowner a free, fixed-price written quote before any work begins, so there are no surprises.

### What is the difference between composite and pressure-treated decking?

Pressure-treated wood costs less upfront but requires annual sealing and may warp or splinter over time. Composite decking costs more initially but needs only occasional cleaning, won't splinter, and holds color for 25+ years. We offer both and help you weigh the lifetime cost.

### Do I need a permit to build a deck?

In most jurisdictions, any deck attached to the house or over a certain height requires a permit and structural inspection. Unpermitted decks can be flagged at resale, may void your homeowner's insurance if someone is injured, and often have inadequate footings. We handle permitting as a standard part of every deck project, no extra coordination required from you.
