Most Houston internet articles copy a consumer plan page and call it business pricing. That is not the same product. And it ignores the one thing that sets your rate: your building.
Houston internet is priced building by building, not by ZIP. A tower in the Galleria has four fiber carriers in the basement. A metal building off the 225 corridor may have Comcast coax and nothing else. Same bandwidth, 3x to 5x the price. The most profitable thing you can do is find out which fiber already touches your building. Before you call anyone.
Houston runs on two products. Your bill tells you which
There are two kinds of business internet here. Broadband and dedicated internet access (DIA).
Broadband is shared. Comcast Business and AT&T Business Fiber sell it. In Houston, 300 Mbps runs about $100 to $150 a month. A gig runs about $200 to $300.
DIA is yours alone, same speed up and down, with a real uptime guarantee. AT&T, Lumen, Comcast Enterprise, Logix, Zayo, and Cogent sell it. Expect 100 Mbps around $400 to $700. A 1 Gbps DIA line runs $900 to $1,800 depending on the building.
Check your bill. Lines like "Network Access and Equipment Fee" or "Connection Pro" mean broadband. SLA language on the order form means DIA.
Who actually serves Houston business addresses
Here is the honest roster.
Comcast Business owns the cable footprint across Harris and Fort Bend. AT&T Business runs fiber heaviest inside the Loop, the west side, Sugar Land, and parts of Katy. Logix Fiber Networks is local to Houston. It sits on-net in hundreds of commercial buildings and is often the second quote you want. Phonoscope lights buildings around the Medical Center and inner-city routes. Tachus covers The Woodlands, Kingwood, and Pearland.
For downtown and Galleria towers, Lumen, Zayo, Cogent, and Crown Castle sell enterprise DIA. T-Mobile and Verizon 5G run $50 to $100 a month and work as backup.
One note. Spectrum is not a real player in Houston. Skip it.
Where competition pushes rates down, and where it doesn't
Some parts of town have real fiber competition. Downtown, Galleria/Uptown, Greenway Plaza, Energy Corridor, Westchase, the Texas Medical Center, The Woodlands Town Center, and Sugar Land Town Square all carry multiple lit carriers.
Other parts are thin. The East End and Ship Channel industrial zone. Pasadena. Baytown. Older strip retail along 290 and I-45 North. Parts of Clear Lake outside the NASA corridor.
The rule is simple. Three or more lit carriers in your building means 1 Gbps DIA should land under $1,000. One carrier means you pay list. That is it.
How to find out who is on-net before you quote
Do this before you talk to a single salesperson.
Ask your property manager for the building's telecom riser list, or the carrier access agreements. Check the MPOE for a Logix or Phonoscope demarc. Use carrier serviceability tools with your suite number, not just the street address. Call a broker or Logix and ask one question: is this address on-net or near-net?
Near-net means fiber runs close but not into your building. Within 500 feet is the number that matters. Past that, you are into a build.
Special construction: the quote that kills the deal
Here is why a quote comes back at $15,000 instead of $150. Construction charges.
A lateral build can run $5,000 to $50,000 or more. It shows up in Katy, Pearland, and industrial east Houston. Look for "Special Construction Charges" and "Customer Premises Build" on the service order.
You have levers. Take a 36-month term and ask them to waive the build. Ask about a construction credit program. Split the build with a neighboring tenant. Or ask your landlord to fund it against the lease. Build charges are negotiable. Most people treat them as fixed. They are not.
The four clauses that cost Houston businesses the most
Auto-renewal. Comcast Business renews for 12 months unless you give written notice 30 to 90 days before the term ends. Put that date in your calendar the day you sign.
Early termination. Comcast charges 75% of remaining monthly charges. AT&T charges the full remaining term on DIA.
Rate escalators. DIA agreements hide 3% to 5% "price adjustment" language. Strike it or cap it.
SLA credits. DIA promises 99.99% uptime, but you have to request credits, usually within 30 days of the outage. Credits cap at one month's charges.
The Houston renegotiation call, scripted
Pull your current bill and your contract end date. Get one on-net competitor quote. If you are on Comcast, call Logix or AT&T. If you are on AT&T, call Comcast Enterprise.
Call retention 90 to 120 days before your term ends. State the competing rate. Ask for a rate match plus a waived equipment fee.
Realistic outcomes: 20% to 40% off broadband, 30% to 50% off DIA in multi-carrier buildings. The honest answer for single-carrier addresses is less. Sometimes much less.
So stop comparing plan names. Start with your building. If you sit in a thin part of Houston, plan your next lease around fiber access, not a better rate.
