Gutter Repair vs. Replacement in Houston: How to Decide
Every week someone asks us the same question from the driveway: "Can you just fix it, or do I need new ones?" It's the right question, and the answer usually comes down to three things you can check yourself before we arrive.
The three-part rule
Age and material. Aluminum gutters last 20 to 30 years in Houston. Galvanized steel rusts through in 15 to 20 here — the humidity and the amount of time they spend wet see to that. If you have aluminum under 20 years old, the default is repair. If you have steel with rust blooms along the bottom, or aluminum from the 1990s that's chalky and thin, replacement is on the table. Not sure which metal you have? A refrigerator magnet sticks to steel and falls off aluminum.
Seamless or sectional. Look at the gutter along its length. If there's a seam with sealant every 10 feet, it's sectional — the kind that comes in lengths from a home-improvement store. Every one of those seams is a leak in waiting. Seamless gutters have joints only at the corners. Repairing a sectional system is fine for one bad seam; if three or four are going at once, the rest are close behind.
How much of it is failing. Count the problem spots. A dripping corner and one sagging run is a repair. If more than a third of the runs need something — re-hanging, resealing, a section replaced — the repair bill starts approaching the cost of new gutters, and new gutters come with a warranty and 20 more years.
What the numbers look like
A typical Houston repair visit is $300 to $600: reseal two corners, re-hang a run, replace a crushed downspout. A full seamless replacement on a single-story home is $1,600 to $2,400. So if your repair list is heading past $800 on a 25-year-old system, you're paying a third of the replacement cost to buy maybe three more years. That's the math we walk through on the estimate.
| Situation | Repair bill | Replacement | Our call |
|---|---|---|---|
| Aluminum, 12 years old, one corner dripping | $150–$250 | $1,600–$2,400 | Repair |
| Aluminum, 18 years old, two corners and a sagging run | $450–$700 | $1,600–$2,400 | Repair, plan to replace in 5–8 years |
| Sectional aluminum, 30 years old, four seams weeping | $600–$900 | $1,600–$2,400 | Replace |
| Galvanized steel, any age, rust along the bottom | $300 buys a year | $1,600–$2,400 | Replace |
| Gutters on soft fascia, any age | can't re-hang | $2,000–$3,200 with fascia | Replace, fix fascia first |
Repairs that are always worth it
Some fixes are cheap, effective and don't depend on the age of the gutter:
- Downspout extensions. $25–$80 each, and they do more for your foundation than anything else on this list.
- Upsizing a downspout to 3x4. About $150. Doubles the capacity of that run.
- Adding a downspout to a long run. $180–$300. Stops the overflow at the far end.
- Resealing a corner. $150–$250. Ten more years from that joint.
- Strapping a loose downspout. $5 in straps. Keeps it on the house through the next tropical storm.
Replacements that are worth it even if the gutter "works"
- Steel gutters with rust. They will fail; the only question is whether it's this hurricane season or next.
- Gutters on rotted fascia. You can't re-hang on soft wood. Fascia replacement plus new gutters is one job, and we explain the fascia side on the fascia and soffit repair page.
- Undersized systems on big roofs. If you've been living with overflow for years, sizing up during a replacement fixes it permanently.
- Gutters on a house you're about to sell. A new $2,000 gutter system photographs well and takes a line off the inspection report; a $600 patch job on 30-year-old gutters still shows up as "gutters at end of life."
What Houston does to the timeline
The 20-to-30-year figure for aluminum assumes normal weather. Houston shortens it. Six months of afternoon storms, a hurricane season that pulls at every loose hanger, and summers where the roof edge hits 150 degrees and the sealant at every corner bakes. A 1990s system in Katy or Pearland that's never been resealed is usually at the end at 25 years, not 30. The First Colony homes in Sugar Land are a good example — 1980s sectional gutters that are all past saving now, which is why full replacement is our most common job there.
What we won't do
We won't sell a replacement to someone who needs a $200 reseal, and we won't keep patching a system that's past saving because the small invoice is easier to say yes to. Either one costs you more in the end. The pricing page has the full ranges, and the estimate you get from us shows both options side by side when both are reasonable. If it's a repair, the gutter repair page describes what that visit looks like.
