What should Flower Mound homeowners know before building a backyard?
Flower Mound has real elevation change on a lot of its lots. Grade is the first thing we solve — retaining and drainage, then the pool, then everything that sits around it.
This is Cross Timbers ground — sandier loam sitting on clay. It digs more kindly than the black prairie further east, but the sand drains onto clay that does not, so grading and drainage get solved before a single stone is set.
In Flower Mound the job is reviewed by the Building Inspections Department, and we file and follow the permit through that office ourselves. Flower Mound requires a permit for any in-ground pool, for an above-ground pool deeper than 24 inches, and for hot tubs and spas.
Longhorn has built across Denton County and the wider Metroplex since 1984. We prepare the drawings an HOA typically asks for, and every project starts with a free design visit and a firm price.

How a Backyard Project Runs in Flower Mound

A free design visit in Flower Mound
A designer comes out to the house, measures, walks the access a crew would need, and talks through what you want the space to do. You leave with a firm price. On Eastern Cross Timbers ground, that is also when the grading, drainage and movement details get decided rather than improvised on site.

Drawings, permit and HOA
We file the permit with Building Inspections Department at the City of Flower Mound and follow it through review. Where an HOA wants a submittal, we prepare the drawings it asks for.

One crew, one schedule
The same team builds the whole job in order, so the slab, the structure, the electrical and the finish work are not three different companies working around each other.

Walkthrough and warranty
We walk the finished backyard with you, settle the punch list and leave one warranty on the work — and we are still Denton County-local if you need us later.
