M&M Santos construction vs Sterling Septic Services Inc.: a closer look
M&M Santos Construction and Sterling Septic Services both serve Conroe and Willis, where in-town homes sit on city sewer but the rural edges and the Lake Conroe shoreline run on septic. Permitting generally goes through Montgomery County Environmental Health Services, with one important exception: systems within 2,075 feet of Lake Conroe fall under the San Jacinto River Authority instead. The area's clay-heavy soils make aerobic spray systems common — and those carry the Texas requirement of a maintenance contract with an inspection reported to the authority about every four months — while heavy rain and nearby floodplains can saturate a drain field.
M&M Santos, based in Cleveland, covers the east side of the county and pairs septic service with a general construction background. It handles pumping, cleaning, repair, and inspection, and the construction side can help on jobs that need site work or access on the rural acreage lots common out this way. Its feedback record is a genuine strength: 4.9 stars across 42 Google reviews, one of the stronger ratings in this directory for a company of its size, which gives a homeowner a real body of experience to read before calling.
Sterling Septic, based in Montgomery, takes a different tack. Rather than pumping or installation, its bio centers on septic design, permitting, and inspection, serving the county since 1998 under president Wes Hubert — a Registered Sanitarian, UT Austin graduate, and former TOWA officer. For a new-construction project that has to clear county or SJRA permitting, that focus is the reason to reach out. Its 4.2-star rating currently reflects zero Google reviews, so weigh the credentials it states and confirm specifics directly.
The practical contrast: M&M Santos offers hands-on service plus site-work capability and a sizable review history, while Sterling offers specialized design-and-permitting help for new builds. Because Google ratings shift over time, confirm licensing, insurance, and current pricing with each company before making a call.
