Short answer
Harris County had 4,731,145 residents at the 2020 census, and 1,968,822 of them lived outside any city, in unincorporated communities such as Spring and Cypress. Our service office on Theall Road in northwest Harris County covers the city and those communities on the same phone line.
What garage doors deal with in Harris County
Harris County is the biggest piece of our coverage and the most varied. Around our Theall Rd office, the typical home dates from the early 1980s, which means doors and springs that have been repaired more than once and openers on their second or third replacement. Further out, master-planned communities built since 2000 have newer doors that mostly need openers set up, first springs replaced and the odd panel swapped after a car backs into one.
The weather is the same everywhere in the county: humid mornings that rust springs, cables and bottom brackets, long hot afternoons that bake bare steel doors, and storms that knock out power. When Hurricane Beryl came through in July 2024, CenterPoint reported 2.26 million of its 2.6 million customers without power, and garages without battery backup openers had to be opened by hand.
The eastern edge of the county is different again. Areas of Harris County east of State Highway 146, including Pasadena, Morgan's Point, Shoreacres, Seabrook and La Porte, sit inside TDI's designated catastrophe area, so replacement doors there need the wind rating a windstorm certificate calls for.

Jobs we do most in Harris County
How visits work across the county
Calls from Harris County are scheduled out of our service office on Theall Road, close to SH 249, US 290 and Beltway 8, which puts the north and northwest side closest. The same line handles the whole county, day and night.
On the phone we ask what the door is doing and whether a car is trapped, so we know what to bring. On site we test the door's balance first, then price the repair before any work starts.
