What matters in Montgomery?
Every documented dcGutterPRO job in Montgomery uses 6-inch seamless gutters with 3-by-4 downspouts. The clearest example is a brick home whose 5-inch back gutters weren't keeping up with what Mac calls "the torrential rain we get in Montgomery," so he replaced them with 6-inch gutters for more capacity. NOAA's records back up the rain: 48.13 inches a year at Montgomery's weather station, and storm bursts estimated at 6.66 inches per hour in a storm the town can expect about every two years. Gutter size is only part of the plan, though. Valleys, downspout spacing, guards and where the water lands still decide each roof.
The job that shows the problem
On August 20, 2026, Mac stood behind a brick home in Montgomery whose 5-inch back gutters weren't keeping up with "the torrential rain we get in Montgomery," as he put it in his job-site video. The back of the house steps around a bay window, a covered patio and a pergola, with tall pines along the back of the lot.
Mac tore off the 5-inch gutters and replaced them with dark bronze 6-inch seamless gutters for more capacity, formed on site with the gutter machine. The crew fabricated a custom inside corner, added dark bronze 3-by-4 downspouts, and upgraded the guards to LeafBlaster Pro stainless steel micro-mesh. See the photos in the 5-inch to 6-inch replacement project, or watch Mac's video from the job.
What NOAA's rainfall records show for Montgomery
NOAA's 1991-2020 U.S. Climate Normals list 48.13 inches of average annual precipitation at the Montgomery, TX weather station. The same record averages 15.8 days a year with at least an inch of rain, and 5.4 days with at least two inches.
A yearly total doesn't tell you whether a gutter will overflow. The heaviest minutes of a storm do. NOAA Atlas 14 estimates that a storm Montgomery can expect on average once every two years brings 2.08 inches per hour over its wettest hour, and 6.66 inches per hour during its wettest five minutes. In a ten-year storm, that five-minute rate rises to 9.58 inches per hour. Those bursts are when every roof section empties into the gutters at once.
Six Montgomery jobs, one gutter size
Every documented dcGutterPRO job in Montgomery so far uses 6-inch seamless aluminum gutters with 3-by-4 downspouts. The houses themselves are different:
- Black gutters with Smart Flow guards on a single-story brick home where two roof valleys sent runoff toward the front porch and door
- Almond box gutters with smooth downspouts and Smart Flow guards on a new stucco-and-stone home in Grand Lake Estates
- Black gutters on a two-story light-brick home, wrapping the upper and lower roof edges and a covered back patio
- A light bronze full wrap with Smart Flow guards on a single-story brick home surrounded by mature trees
- Beige gutters on a newly built covered patio, added after the contractor finished the patio and its foundation
On the black-gutter home with the two valleys, Mac named heavy Montgomery rain as an important condition for the water-management plan. It is the same concern behind the 5-inch replacement.
Bigger gutters need enough downspouts
A 6-inch gutter only helps if the water can get out of it. On three of these jobs, the two-story light-brick home, the light bronze full wrap and the Grand Lake Estates home, Mac placed 3-by-4 downspouts at intervals of about 30 feet. Where roof valleys concentrate runoff, as they did near the front porch of the black-gutter home, the layout has to give that water a managed path into the system. Downspout placement is planned with the gutter, not added afterward.
Where the water goes after the gutter
Across these jobs, homeowners asked for the same result in different words: keep water away from the foundation, porches, garden beds and patio slabs. On the covered-patio addition, the goal was to keep roof water from flooding the new outdoor space and washing across its newly poured foundation. Where each downspout lets water out decides whether that happens, so outlet locations belong in the plan from the start.
When a 5-inch system should be replaced
If your gutters spill over the front edge in hard rain, the first question is whether they are clogged, short on downspouts, or simply too small. Cleaning or gutter repair handles the first, and the second may only need added downspouts. When the gutter itself can't carry what the roof sheds, as on the Montgomery brick home, gutter replacement with 6-inch seamless gutters is the fix. Mac checks which of the three applies at the roof.
What a 6-inch system costs
dcGutterPRO's current starting prices: installed 6-inch seamless gutter runs $11–$13 per linear foot, with a $1,600 minimum installation project. Smart Flow guards add $4–$5 per linear foot, and LeafBlaster Pro stainless micro-mesh $10–$12. At those rates a 100-foot run works out to $1,100–$1,300, so a job that size is priced at the $1,600 minimum. The written estimate sets the final price after Mac measures the roof and checks the downspouts, access and removal. See all starting prices.
What to check before Mac visits
- Where water spills over the gutter during a hard rain, and whether it happens at a valley or along a long run
- How many downspouts serve each side of the house, and where each one lets water out
- Staining, erosion or splash marks along the foundation, porch or patio edge
- Trees over the roof and the debris you find in the gutters
Photos or a short video of the gutters during a storm help most. Montgomery's rain is heavy, but the right gutter size, downspout layout and guard choice still come from your own roof.
Confirmed considerations for this area
- NOAA's 1991-2020 normal for the Montgomery, TX weather station is 48.13 inches of precipitation a year, with an average of 15.8 days reaching at least one inch.
- NOAA Atlas 14 estimates that a two-year storm in Montgomery peaks at 6.66 inches per hour over five minutes, the kind of burst that tests gutter and downspout capacity.
- All six documented dcGutterPRO jobs in Montgomery use 6-inch seamless gutters with 3-by-4 downspouts, and three of them record downspouts at about 30-foot intervals.
- Four of the six Montgomery jobs include gutter guards, Smart Flow on three homes and LeafBlaster Pro on the 5-inch replacement; the guard choice still follows each roof's debris.
