Glen and Alex were great to work with. Very responsive, easy to schedule, their quote was less than others I got, and most importantly their gutter fab and install was flawless. Great local company!

The Pro-Flow Gutters Company replaced all my gutters and downspouts in October 2024. When I recently reported a water intrusion issue, Glen, the owner, responded promptly and scheduled an inspection within two days. Glen’s initial theory was that a sealant used at the junction where the downspout, T-Rex, and gutter meet might have caused the water intrusion. He personally investigated the issue rather than delegating it to his team and discovered another sealant inside the gutter that may have restricted water flow. That sealant had likely been applied by my roofing company during a previous roofing modification. To resolve the problem, Glen removed all the sealant, then replaced the existing T-Rex with a new one after creating a proper downspout opening instead of using any sealant. The result looks clean and professional. I was also pleased to see that he used a brand-new T-Rex piece instead of reusing or patching the old one. In addition, his team member, Alex, was very kind and took the time to locate and pick up many nails left behind by my roofing company. I truly appreciated Glen and his team’s prompt response, thorough investigation, and high-quality workmanship.

We had a gutter hit by tree branch - was going to replace all the gutters . We called Pro Flo Gutters , Glen and Alex came out and suggested not to replace them all just the damaged areas and a couple down spouts that were not working properly . They saved us a ton of money by being honest . We had another company come out for a bid and they wanted over $ 4,ooo.oo . We can't thank them enough because we are SC and are on a fixed income - Great Family owned Bus We suggest them to all of our family and friends

They were so responsive when I asked for a quote. They scheduled me right away and came out and did an excellent job! They are professional, friendly, and do super work. I am very pleased and will recommend them to everyone. The cost was literally half of what one of the "name brand" outfits quoted me. These guys are the best!

Pro Flow Gutters serves Duvall with seamless gutter installation, Alu-Rex gutter guards, repair and cleaning. We also install gutters on shops and barns, and place downspouts so water drains away from your buildings.

What we do in the area

Seamless gutter installation

Seamless gutters for your house, and for a shop or barn that never had any.

Gutter guards

Perforated aluminum guards, not mesh or foam. They keep fir needles out without holding water.

Gutter repair

Wet needles are heavy. We fix sagging gutters and loose brackets.

Gutter cleaning

Cleared by hand and downspouts flushed. Under heavy fir, three cleanings a year is realistic.

Common questions

About three times a year. With good gutter guards, most homes only need the top of the guard brushed off now and then.

Yes, often. Large barn and shop roofs usually need 6-inch gutters and oversized downspouts. More on outbuilding gutters.

Away from the building, somewhere the water can soak in or run off. Extending a downspout is a small job that prevents costly water damage.
