About us

A family gutter business in Sultan, WA

Glen and his crew have installed, repaired and cleaned gutters across Snohomish, King and Skagit Counties for 14 years.

Pro Flow Gutters is a family-run gutter company at 31503 SR 2 in Sultan, Washington. Glen runs the business and is on site for most estimates and many installs, alongside Alex and the crew. Our own crew does every job.

What we do

We make seamless aluminum gutters on site and hang them on Alu-Rex T-Rex brackets. We also install Alu-Rex gutter guards, replace downspouts, and clean and repair existing gutters.

We offer a lifetime guarantee for both our workmanship and our products.

We don’t do roofs, siding or windows. We focus on gutters so we can do them well.

How we work

We tell you when you don’t need us. Our reviews mention this more than anything else. Some customers who called about a full replacement only needed two sections and a downspout repaired.
We make gutters on site. Each gutter is made in one piece to fit your house. No seams in the middle, so nothing to leak or split.
We hang on brackets, not nails. T-Rex brackets hold far more weight than nails or hooks, and they stay tight through years of freezing winters.
We clean up. We haul away the old gutters, sweep up and pick up every nail.

Why customers hire us again

Many customers have hired us for their second or third property. They tell us it’s because we answer the phone, send estimates quickly and charge fair prices.

We’re rated 5.0 on Google. Read what customers say about how we handled rotten boards behind their gutters and a sealant problem traced back to another company’s roofing work.

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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

 Trustindex verifies that the original source of the review is Google. 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!
