Three figures that agree, which almost never happens here
| Where it comes from | Figure |
|---|---|
| This Old House survey of 1,000 homeowners | $39.59 per foot, $7,919 for 200 feet |
| Leafguard's own financing page, as reported by This Old House | $7,883 for an installed job |
| Leafguard reviews on BBB and Trustpilot, as read by This Old House | $3,600 to $16,000 |
The first two are $36 apart, our subtraction, which is under half a percent. The third is a wide band, but it contains both.
Across this whole gutter cluster we have mostly been explaining why published figures disagree, sometimes by a factor of fifteen. This is the opposite case. A survey of what buyers paid, a number the company itself uses to calculate monthly payments, and what reviewers volunteer in public all point at roughly $7,900 for a standard house, our rounding of the two figures above. Our reading, marked as ours: that is about as good as consumer pricing evidence gets for a product whose maker, as This Old House notes, publishes no prices at all.
What it costs by house size
| Home size | Gutter length | Average cost |
|---|---|---|
| 1,000 sq ft | 100 ft | $3,959 |
| 1,500 sq ft | 150 ft | $5,939 |
| 2,000 sq ft | 200 ft | $7,919 |
| 2,500 sq ft | 250 ft | $9,898 |
| 3,000 sq ft | 300 ft | $11,877 |
| 3,500 sq ft | 350 ft | $13,857 |
| 4,000 sq ft | 400 ft | $15,836 |
This is a straight multiplication of $39.59 by the footage, so treat it as a rule of thumb rather than five separate measurements. This Old House adds that respondents with systems of 200 feet or more reported prices above $10,000, and that roof shape, condition and access all move the figure.
The thing most comparisons get wrong
Leafguard does not sell covers for your existing gutters. As This Old House puts it, Leafguard builds the guard into its own gutter system, so you buy the complete system rather than just the protection.
That changes every comparison you will read.
| Brand | Per linear foot | 200 feet | What you get |
|---|---|---|---|
| Leafguard | $39.59 | $7,919 | new gutters with integrated guard |
| LeafFilter | $41.72 | $8,344 | guards fitted to your existing gutters |
Read straight off that table, LeafFilter is about $425 dearer, our subtraction. This Old House states the gap as $424, which comes from rounding their LeafFilter figure to $8,343 in one place and $8,344 in another.
Our arithmetic, marked as ours. That $425 only describes the case where your existing gutters are sound. If they are not, the LeafFilter route needs new gutters first, which our installation page puts at about $3,200 for the same 200 feet. That is $8,344 plus $3,200, or $11,544, against Leafguard's $7,919. The gap is then $3,625 in Leafguard's favour, not $425. Neither source does this calculation, and neither frames the two products as answering different questions.
Two honest caveats on that figure. The $3,200 is an installation price, and tearing out the old gutters is charged separately, so the LeafFilter-plus-gutters route is if anything further ahead of $11,544 than we have shown. And neither source states whether Leafguard's own price includes removing what is already there, so we are not going to assume it either way.
The reverse is just as true. If your gutters are three years old and perfectly good, paying for a whole new gutter system to get a guard is money spent on something you already own.
The older band, and why it is lower
Bob Vila's gutter guard guide, last updated in November 2023, puts Leafguard at $8.90 to $32.79 per linear foot, which on 200 feet is $1,780 to $6,558 by our arithmetic. That is a 3.7-fold spread inside a single brand, and its top end sits below the 2026 survey average.
We saw exactly the same pattern on the LeafFilter page: the older aggregated figures run below what the 2026 survey respondents say they paid. Our reading, marked as ours: two brands showing the same direction of drift over the same three years is weak evidence that the branded gutter guard segment has got dearer, but it is only two data points from one survey, and we would not want it read as more than that.
What the money buys besides mesh
Bob Vila notes that surface tension guards generally struggle in heavy downpours, where the rush of water can break the surface tension the design depends on, and reports that Leafguard has been tested to work in rainfall up to 32 inches an hour, which Bob Vila describes as three times more rain than has ever fallen in an hour in the United States.
This Old House's own recommendation splits the two brands by purpose: Leafguard for homeowners who want a seamless look, LeafFilter for better debris blocking.
Before you sign
- Establish whether your gutters need replacing anyway. This single question moves the comparison by more than three thousand dollars, as above.
- Get the footage, then divide. Your total divided by your linear feet is the only number comparable with $39.59.
- Ask what happens to the old gutters. Removal is a real line item: Fixr prices it at $1.31 to $2.38 per linear foot, as our replacement page sets out.
- Treat the $3,600 to $16,000 review range as the real world. The average is a good anchor. It is not a quote.
