Pools & Spas in Sherman
Gunite pools and spas planned with the deck, shade and kitchen.
Outdoor living is the covered patio, pool, kitchen, stone and lighting that make a backyard part of the home. Longhorn designs and builds them together for Sherman homeowners in Grayson County, with one family-owned team.

Sherman is in central Grayson County, seventy-five miles north of Dallas on U.S. Highway 75, and is also crossed by U.S. Highway 82 and State highways 11 and 56. The town first stood on a hill and moved three miles east in 1848.
That ground decides how a slab, a pool shell or a footing has to be built here. Here is what it does to a patio.
We file the permit with the city or county office that covers Sherman and follow it through review, so the schedule doesn’t stall on paperwork.
Longhorn has been building since 1984, and every project starts with a free design visit and a firm price.

Sherman was named county seat by the act that created Grayson County on March 17, 1846, and was named for Gen. Sidney Sherman. A post office opened in 1847, and the Houston and Texas Central Railway arrived in 1872.
In an older county seat, a covered porch or pergola with classic columns and a roof tied into the original house suits homes with a long history.
Grayson County covers 934 square miles at elevations from 600 to 800 feet. Average temperatures run from a January low of 30° F to a July high of 96°, and annual precipitation averages thirty-seven inches.
Water comes from the City of Sherman, which treats surface water.
Two fires in 1875 destroyed the buildings south of the city square and all but two east of it, and much of the city was rebuilt with better materials. Austin College moved to Sherman from Huntsville in 1876, and a public school system began in 1883. A tornado on May 15, 1896, destroyed some fifty homes.
By the mid-1920s Sherman had 15,031 residents and fifty-four industrial plants making goods such as flour, cottonseed oil and hardware, which earned it the nickname Fifth Industrial City of Texas. It also had six private academies and colleges, six public elementary schools and two public high schools.
NOAA’s Storm Events Database lists 181 hail reports in Grayson County from 2016 to 2025, 144 of them an inch across or larger, with stones up to 2.5 inches. 7 of those reports were logged at Sherman itself, the largest 1.75 inches. The same records show 93 damaging thunderstorm wind reports, with gusts up to about 90 mph, and 5 tornadoes. That is why a patio cover’s roof panels, fasteners and posts here are chosen for hail and wind, not only for shade.
Blackland Prairie clay swells through a wet spring and shrinks hard by August, and a pool shell is a rigid object sitting in ground that moves around it. Here that means the shell, the beam and the deck are engineered for that movement from the drawing stage, and the flatwork gets its control joints placed on purpose rather than wherever the pour ends. In Sherman the permit goes through the city or county office that covers Sherman, and Longhorn files it and follows it through inspection. More on pools.
Blackland Prairie clay lifts and drops with the season, so a patio cover’s footings are the whole job. Posts set in shallow pads move with the top of the soil and take the roofline with them; footings taken below the active zone, tied to a slab that drains away from the house, do not. In Sherman the permit goes through the city or county office that covers Sherman, and Longhorn files it and follows it through inspection. More on patio covers.
On Blackland Prairie clay a pergola’s posts are what decide whether it still stands square in five years. The clay moves most in the top few feet, so footings go deeper than the movement rather than resting in it, and the slab underneath gets its own drainage plan. More on pergolas.
A sunroom or screened enclosure in Sherman is attached to the house, so it is permitted through the city or county office that covers Sherman and sits on footings designed for the ground under it. We match the roofline and the exterior to the house so it reads as part of it. More on sunrooms and patio enclosures.
Almost always, for pools and for anything attached to the house, including patio covers, sunrooms and enclosures. Longhorn files the permit with the city or county office that covers Sherman and handles the inspections, so the schedule does not stall on paperwork.
Sherman sits on Blackland Prairie ground in Grayson County. The ground decides how a slab, a pool shell or a footing has to be built, so we plan the drainage and the footings for it at the first visit rather than after something moves.
