Deck Builders for Canyon Lake Homes
An older deck on rocky ground can look fine on top and still be tired underneath. Around Canyon Lake, our deck builders find where the limestone and the easement line sit before we draw a new deck.
How high off the ground will a new deck sit?
Usually about level with the door you step out of, give or take a step. Where the yard drops away from the house, the outer edge of a new deck can end up well off the ground. A higher deck needs a guard on its open sides, taller posts and longer stairs, and each one adds to the price. We measure the drop, and the height of any old deck that's there, before we settle on a size.
Rock under the footings, and the county's permits
On much of the high ground up here, rock sits close to the surface, so we plan the footings around where the limestone sits on your lot before we draw the deck. On an older deck, we look under the boards before we talk about new ones: posts settle, joists go soft at the ends, and the stairs down to the yard work loose.
There's no city here. Canyon Lake is unincorporated Comal County, so the permits are the county's. For a new deck, that means the county's floodplain development permit, which the county uses to see whether the deck sits in a flood hazard area, and a deck that does has to meet the county's floodplain standards.
What we do for decks at the lake
Raised decks on the slopes up here hide their trouble underneath. So we often start with an inspection: the posts, the joists, and every stair down to the yard.
No deck on the lot yet? We'll plan a composite deck that steps out from your back door and down the slope. On an older deck, posts or joists too far gone to trust mean we replace the whole deck. When the frame is solid and only the top has worn out, resurfacing is the job. Comal Decks puts the new boards on the frame you have.
The easement line and the lake's high water
Near the water, one line on the map comes first. Around Canyon Lake, private land below the 948-foot elevation line is generally flowage easement land, so before we sketch anything, we find out which side of it your deck would sit on. If the deck would sit in the county's flood plain, the Army Corps of Engineers has to give its consent before the county issues that permit, so we plan the start date around both.
The lake can come up fast, too: in one week of July 2026 it went from just over half full to nearly full. A deck near the shore is planned for water that high.
Neighborhood approval, and a quick check of your deck
Some neighborhoods want to see the plan first. In Mountain Springs Ranch, the neighborhood's architectural committee wants an application for a deck, the same as for a pool or a fence. If that's you, we finish the design before you apply, so the committee sees the deck we'll really build. Meanwhile, give the deck you have a once-over:
- Press on the boards by the house and along the outer edge, and note any that give.
- Grab the railing and see if it moves.
- Walk the stairs down to the yard and feel for a loose step or a lean.
Frequently asked questions
Is my old deck worth keeping, or should it come out?
It comes down to the frame. If the posts stand straight and firm, the joists are solid and the deck's still fastened snug to the house, keep it. New boards or railings can go on top. If the posts have shifted or the joists crumble at the ends, new boards won't fix that, and a full replacement is the better spend.
Thinking about a new deck by the water?
Photos help us most. Send one of the deck from the yard, one from underneath and one of the view from your back door. Know your lot's elevation? Add that too.
