River Islands Gutter Solutionists
Gutters for River Islands’ new homes on the island
River Islands is Lathrop’s master-planned community on Stewart Tract, an island in the San Joaquin River, west of Interstate 5. The City of Lathrop describes it as nearly 5,000 acres planned for about 15,000 homes, with lakes, walking trails, parks and a boathouse, and building started in the neighborhood called the Community at South River Bend. The island is ringed by levees that are 100 to 300 feet wide at the top, built to a 200-year flood standard. Nearly every house is new: in census tract 52.14, which covers River Islands, 71 percent of homes were built in 2010 or later and the median year built is 2015. The Tracy Carbona station, the nearest NOAA gauge with an official normal, about eight miles south, averages 12.72 inches of rain a year.
Mohammad Awadalla and Syed Rizwan, a family team, own The Brothers That Just Do Gutters San Ramon, and our crews reach River Islands over the Altamont from our base in Livermore. Seamless gutters are formed in your driveway from aluminum, copper or galvalume, 5, 6 or 7 inches wide, and we also clean the runs and flush downspouts, repair leaks, sags and rotted fascia, put on BroGuard stainless micro-mesh, and connect downspouts to underground drainage so roof water ends up where the lot was graded to send it. We are licensed under CSLB #1115646, insured, and rated 4.9 stars on Google.
A new house does not mean the gutter work is finished. Some homes here need extra downspouts or bigger outlets once owners see where water actually runs off the roof in a real storm, and patios, side yards and lakefront lots added after move-in can change where it should go. The trees planted along these streets are only a few years old, but each fall they get bigger and drop more. The rain here is light by Bay Area standards, so it is easy to forget the gutters until a February storm finds the one clogged outlet.

Why the Brothers
Why River Islands Homeowners Call the Brothers
On a new home we check where every valley and slope sends water and add downspouts or larger outlets where one is not enough.
If your street has design rules, we can match gutter color and profile to what is already on the house and give you specs for approval.
New runs come off the gutter machine in one piece, cut to your eave, and match the profile already on the house.
Mohammad Awadalla and Syed Rizwan run the franchise from Livermore, over the Altamont. Call (925) 905-9555 to reach their team.
Year-round
Your River Islands gutter calendar
A gutter year for River Islands, built around rain that peaks in February and almost disappears from June through September.
- Fall · Oct to NovFirst clean of the season
Leaves and summer dust cleared, downspouts flushed, and outlets checked before November rain starts.
- Winter · Dec to MarSee where water goes
December through February brings 7.23 inches on average. A storm is the best time to spot where a roof needs another downspout.
- Spring · Apr to MaySecond clean and upgrades
Spring debris cleared, and a good time to add downspouts or BroGuard before the dry months.
- Summer · Jun to SepDrainage projects
Only 0.26 inches falls from June through September, so summer is right for trenching drain lines and adding runs.

Posted on GoogleRiver Islands Gutter Questions, Answered
New homes still have gutter questions. A roof can send more water to one corner than a single downspout can handle, and a patio or side yard added after move-in may need its own drainage. In tract 52.14, 71 percent of homes were built in 2010 or later, so most of our River Islands work is adding outlets, extending runs and tying downspouts into drains.
Yes. We form seamless gutters on-site in common profiles and colors, so an added run or a replacement section can match what is already on the house. If your street has HOA design rules, we will give you the profile, color and downspout plan in writing so you can submit it for approval before any work starts.
Two to four times a year, depending on the trees near your roof, and the fall clean before the rain is the most important visit. The Tracy Carbona station averages 12.72 inches a year, and 7.23 inches of it falls from December through February. As the street trees grow, plan on the extra visits, or add BroGuard mesh to keep leaves out.
Into the drainage the lot was built with, or far enough from the house that water runs to the yard drains or the street. Stewart Tract is flat, so water from a short downspout tends to sit by the foundation. We can extend outlets, add splash blocks, or connect downspouts to underground lines that carry water away from slabs and patios.
Yes. We work throughout River Islands, from the Community at South River Bend and Marina Drive to the streets around Michael Vega Park. Our crews also cover the rest of Lathrop, plus Manteca, Tracy, Mountain House and Stockton. Give us a call at (925) 905-9555 to set up a free estimate.
