Deck & Patio Builders in Leander, TX

All Seasons started in Leander in 1984, when Peter Toomey founded the company here. Since then Leander has grown from a small town into a city of master-planned communities, most of them on rocky Hill Country ground and most with an HOA. We build decks, patio covers, pergolas, gazebos, screened porches and outdoor kitchens across Leander, and we handle the city permit and the HOA submission.

"Dad started this company in Leander in 1984, and our shop is just up the road in Liberty Hill now. Most Leander homes are newer, so the question is usually how to attach to the house the right way. That means a flashed ledger bolted to the rim, not nailed to siding. Get that wrong and you've got water in the wall."

Building a Deck or Patio in Leander: What to Know

Permits in Leander

Leander permits are issued by the City of Leander through its Development Hub under the 2021 IRC. Inspections requested before 4 pm are usually done the next business day. Homes in the ETJ generally only need city permits for water or wastewater connections. We handle the submittal and inspections.

HOA approval

Nearly every newer Leander subdivision, including Crystal Falls, Travisso, Bryson, Mason Hills and Summerlyn, has an HOA with architectural review. Expect to submit a site plan, elevations, materials and colors. Some communities also limit structure height or visibility from the street or golf course. We read your community's current guidelines, prepare the package, and wait for approval before filing with the city.

Soil and footings

Most of Leander sits on Hill Country limestone with thin, rocky soil. Footings on those lots are drilled into rock. Lower areas and creek bottoms can have deeper clay that moves with moisture, so we probe every site. On new-construction lots, disturbed fill near the foundation also needs to be dug through to firm ground.

Weather and materials

  • Hot, dry summers with strong UV favor capped composite and aluminum or insulated roof panels.
  • Hilltop lots catch more wind, so pergolas and freestanding covers need solid post anchoring.
  • Hail is a spring risk; avoid thin polycarbonate roofing.
  • Afternoon shade on the west side of the house makes the biggest comfort difference.

Tips from our crew

  • Confirm whether you are inside city limits or in the ETJ. It changes whether the city permits your deck at all.
  • If your lot backs to a greenbelt, check the plat for drainage easements before picking a deck size.
  • Leander inspections requested before 4 pm are usually done the next business day, so a project rarely waits long on an inspection.
  • On brick or stone veneer homes, ask how the ledger will be attached. The answer tells you a lot about the builder.

Leander-Specific Considerations

Attaching to Newer Homes

The challenge: Most Leander homes are recent builds with brick or stone veneer and siding. A deck or cover attached the wrong way traps water behind the veneer or siding.

How we handle it: We attach through to the house framing with a properly flashed ledger, or design the structure to stand on its own posts when attachment would compromise the wall.

Two Approvals, in Order

The challenge: Crystal Falls, Travisso, Bryson and most newer communities require HOA approval, and the City of Leander requires a permit for decks, patios and patio covers.

How we handle it: We submit to the HOA first, then file with the city through its Development Hub once the HOA signs off, so nothing gets redesigned twice.

Slopes and Rock

The challenge: Many Leander lots, especially on the west side, slope and have limestone close to the surface.

How we handle it: We drill footings into rock and step decks with the grade. A two-level design often keeps the upper deck lower and the stairs shorter on a falling lot.

"Being based in Leander matters. Our neighbor recommended All Seasons - they'd built decks for several families on our street. That local reputation sold us. The deck they built is beautiful, but more importantly, they were professional, on time, and exactly as described. That's rare in the construction world."

FAQs for Leander Homeowners

Yes, inside city limits. The City of Leander requires permits for decks and patios, for covering an existing slab, for multi-level decks and for arbors, through its Development Hub under the 2021 IRC. Homes in the ETJ generally need city permits only for signs and water or wastewater. We handle the submittal and inspections.

Close. The company started in Leander in 1984, and our shop is now at 2401 Co Rd 258 in Liberty Hill, just northwest. Site visits for free estimates are easy to schedule, and the same crew runs your project from start to finish.

Often, yes. If the slab is sound, a cover goes over it and saves the cost of new concrete. Our published examples run $15,000 to $22,000 for a 12x20 aluminum cover and $32,000 to $45,000 for a 16x20 insulated cover with fans. Covering an existing slab still needs a City of Leander permit and inspection.

Capped composite, where a polymer shell protects the core from fading and staining. Trex and TimberTech capped lines run $35 to $55 per sq ft installed in our pricing. Lighter colors stay cooler under full sun.

Our published examples: a 12x16 basic deck runs $12,000 to $16,000 and a 16x20 composite deck $20,000 to $28,000. A 400+ sq ft multi-level deck on a sloped lot runs $35,000 to $55,000. Your written quote is fixed.

Generally not a city building permit. Leander states that ETJ homes generally only need city permits for signs and water or wastewater connections. Your HOA and any floodplain rules can still apply, and we check both.
