Security Services

Houston

60 businesses listed, showing 1–40. How we order them.

Houston has 60 security service listings on SiteCity, clustered most heavily around 77060, which holds 7 of them. Zip codes 77002, 77074, and 77079 each carry 5 listings, with 77081 close behind at 4. If you're near one of those areas, start your search there before widening out, since that's where the most options sit close together. All 60 listings include a phone number, and 56 have a website link, so you can usually check a company's site before you dial. Call two or three that fit your budget and coverage area, and ask directly about licensing, response times, and contract terms, since that detail isn't something a directory listing can capture for you.

More about security services in Houston ↓

None of the security service listings in Houston currently carry a Sponsored tag, because paid placement for this category hasn't been switched on here, so the order you see reflects plain directory sequencing rather than a promoted lineup. If you operate one of these companies and notice a missing website or outdated contact info, you can claim your listing and update it yourself, which helps a homeowner or business owner in a zip like 77036 or 77092 reach you without extra digging.
