How Bulldog works.

Bulldog Gutter Guard is an aluminum insert that drops into your gutter in 6-foot panels. Its patented ribbed design lets rainwater through tiny pores while leaves, seeds and pine needles stay on top, and air moving over the ribs helps the wind blow them off. It attaches to the gutter and fascia, never to the roof, and it’s made in the USA by GPI Gutter Products.

What Bulldog keeps out

  • Oak leaves
  • Helicopters and tassels
  • Acorns and caps
  • Pine needles
  • Seeds
  • Rotted material
  • Twigs and sticks
  • Pine cones
  • Bird nests

Shingle granules are small enough to pass through the pores, and the rain washes them out of the gutter.

What our customers say

I had a great experience with Next Day Gutters. Doug who came out to give us a quote was very professional and knowledgeable in the industry. The installation was quick and efficient and they walked with me around the whole home confirming everything that we wanted completed. We went with the black color gutters around the whole house and it turned out amazing. I would definitely recommend Next Day Gutters to anyone in the area interested in replacing or adding new gutters to their home.

Bulldog gutter guard FAQs

What is Bulldog Gutter Guard?

An American-made aluminum gutter insert with a patented ribbed design and tiny pores. Rain goes into the gutter, and leaves and debris stay on top until the wind blows them off. It drops into the gutter in 6-foot panels and attaches to the gutter and fascia.

What warranty comes with Bulldog?

GPI Gutter Products, the manufacturer, offers a registered 25-year limited warranty. It covers the painted finish against peeling, flaking, chipping, cracking and blistering, and it covers the gutters against clogging and overflowing from leaves, twigs, needles and seeds. The gutters have to be cleaned, properly sloped and have clear downspouts first, which we take care of when we install. Read the full warranty.

How much rain can Bulldog gutter guards handle?

The manufacturer says that when it’s properly installed, Bulldog handles more than 12 inches of rain an hour, the heaviest one-hour rainfall recorded in the U.S. Hurricanes produce up to about 6 inches an hour.

Is Bulldog maintenance-free?

No gutter guard is. Dry leaves usually blow off in a breeze of about 5 mph, and wet or packed leaves need about 20 mph. If your trees drop a lot of tassels or pine resin, the top of the guard needs an occasional cleaning.

Will Bulldog work with my existing gutters?

Yes. It installs over existing gutters, and we clean and tighten them first. If they’re too worn, we can replace them with seamless gutters before the guards go on.

Will Bulldog change how my house looks?

Not much. It sits low in the gutter, so it’s hard to see from the ground, and it comes in white, dark bronze or black to match your gutters.

What gutters does Bulldog fit?

K-style, box and half-round gutters in 5-, 6- and 7-inch widths, plus a 4.5-inch fascia size. A step-up profile clears screw-in gutter hangers like the ones we use.

Is Bulldog screwed into my roof?

No. It attaches to the gutter and the fascia board and leaves your roof alone.

Will Bulldog gutter guards prevent ice dams?

No guard prevents ice dams, because they come from poor attic insulation and ventilation. Bulldog won’t cause them either. It can cut down on ice building up in the gutter, which helps prevent seams separating, hangers loosening and gutters pulling away from the house.

How much do Bulldog gutter guards cost?

It depends on how many feet of gutter you have. We measure at your free estimate and give you a written proposal with a firm price.

How does Bulldog compare to micro-mesh gutter guards?

Bulldog is a ribbed aluminum insert. Micro-mesh guards use a fine mesh to stop smaller debris. We install both, including Klear Micromesh, Gutterglove Pro, MicroMesh Pro and Leaf Blaster Pro, and we bring samples so you can compare. See all the gutter guards we install.

Where do you install Bulldog gutter guards?

Across Maryland, Northern Virginia, the Richmond area, Washington, DC, Delaware and North Carolina. Book a free estimate and we’ll come to you.

Can I get an estimate from photos?

Yes. GutterSnap is our photo estimate technology: you take photos of your home and we use them to put together your estimate. If you’d like to use GutterSnap, contact us first so we can get a few details from you.
