  Our old gutters were pulling away from the fascia and every heavy storm meant water pouring down the side of the house. FlowLine came out to look at the whole system and gave us a couple of options depending on budget. We ended up doing a full gutter replacement plus the guards, and they talked us into the bigger downspouts because our roof dumps a lot of water in one spot. That turned out to be the right call. The estimate was clear and there weren't any surprise costs once the work started. The install itself was quick, they had the whole thing done in a day. What I noticed most is how much better everything drains now. During the first big rain after they finished I went out and watched it just because I was curious, and the water was actually going where it was supposed to instead of spilling over the front. The guards have kept the leaves out too, which was a big reason we did this in the first place since we have a lot of trees. The team was polite and answered my questions without any attitude about it. Solid company to deal with if you need real gutter work done and not a patch job.

  Had FlowLine replace all the gutters on the house along with new guards.The new setup handles rain way better than the old sagging ones did, and no more clogged mess up there.

  new gutters with the bigger downspouts and the guards. old ones were tiny and clogged every fall. checked a few places in glenview before picking these guys. quote was clear, install took most of a day. the oversized downspouts make a huge difference when it rains hard, water actually moves through instead of overflowing. color matches the trim too which i was worried about. work looks clean from the ground

  Every heavy rain we had water sheeting over the front gutter and pooling against the foundation. The basement was starting to get that musty smell after storms and I knew it was tied to the gutters not doing their job. The old ones were undersized and full of debris from the maples out front. FlowLine came out, looked at the slope and the downspout layout, and recommended bigger gutters with oversized downspouts on the corners that take the most water. They also added guards since trees aren't going anywhere. After the install we had one of those summer storms that usually had me watching the foundation, and the water just moved. No overflow, no splashing onto the siding. Looked at a couple of options in Glenview and these guys gave the most direct answer about what was actually wrong.

  Had our old gutters pulled off and replaced with a full new system, plus they added the oversized downspouts since the old ones could never keep up in a heavy rain. The quote process was painless. The estimator actually walked the whole perimeter of the house, pointed out where the previous installer had pitched things wrong, and explained why water kept pooling near the back corner. He wasn't trying to upsell, just laid out what made sense and what could wait. Install day the crew got there early and worked steady through the afternoon. They were careful around the landscaping, which I appreciated because I have hostas right up against the foundation that took years to fill in. The new gutters look clean against the fascia, no gaps, no sloppy seams. First big storm rolled through last week and everything actually drained the way it's supposed to.

  Water was running behind our gutters every storm and pooling against the foundation. FlowLine came out, took a look, and explained that the old gutters were undersized and pitched wrong. They put in new seamless ones with bigger downspouts …

  got new gutters and oversized downspouts put in by FlowLine and the amount of water these things move is crazy. we have a pretty big roof and the old system just couldnt keep up when it rained hard, water would spill over the edges constantly. the new setup handles everything, even during a heavy downpour last week there was zero overflow. they also put gutter guards on which im glad about because we have a ton of trees and i was always up on a ladder cleaning leaves out before. the downspouts are noticeably wider than what we had and they routed them really well away from the foundation. whole thing just looks clean and works the way its supposed to. pretty satisfied with how it all turned out

  Flowline replaced all the gutters on our two-story and the difference during heavy rain is obvious. Water actually flows into the downspouts now instead of pouring off the edges. Everything lined up tight along the roofline.

  Every spring we used to have heavy runoff from the back of the house because the old gutters had separated at several joints. The fascia was also showing signs of wear, with some discoloration creeping in. FlowLine came out and assessed the …

  The estimate process was quick and they explained everything without being pushy about extras. Installation day was smooth and the crew worked efficiently. The new gutters and gutter guards look great and fit the house well. Getting updates along the way was nice, no guessing about when things would happen.

  We had this persistent issue where water would cascade over the front gutters during any moderate rain, and it was eroding the mulch beds along the walkway pretty badly. Spent two years just kind of dealing with it, putting down new mulch every spring like that was a real solution. FlowLine replaced all the gutters on the front and both sides, upsized the downspouts too which I think made the biggest difference. First real storm after the install I stood at the Glenview kitchen window watching and nothing spilled over. Mulch stayed put.

When preparing your home for autumn, don't overlook the gutter system. Falling leaves can quickly collect inside open gutters and create blockages, especially before the first major rains of the season. Gutter guards provide a barrier that helps keep leaves and debris out while allowing rainwater to flow through. Installing them before leaf season gives your drainage system a better chance of handling heavy fall rainfall without overflow or unnecessary water exposure around your home.Aug 18, 2026Call now
