"Was only going to have the gutter/downspouts cleaned, but ended up buying the LeafFilter product. The presenters' explanation/demonstration was excellent. The installer was efficient and courteous! The warranty is outstanding."

"Ray the owner was on time, worked fast and did a great job. Our house will sell better because of our sparkling windows. He was friendly and even washed the two little windows on our shed for no charge that were not included in the bid.Our bid also included cleaning out our window wells and cleaning those windows. He did an excellent job. His prices are low. He is a veteran and hires veterans in his business. I would definitely recommend this company for windows and gutter cleaning."

"Ralph Bertrand from Home Genius Exteriors came out to thoroughly examine our roof. Ralph showed us many photos & a video of our roof, outside & inside. Ralph took the time to answer any questions we had. He explained the various products used & levels of warranty available. We really appreciated the time Ralph spent explaining everything to us, all without pressure to buy. The day of install arrived & the team was on time & ready to work! One thing we liked was that there was someone there from Home Genius Exteriors during the whole time of install. Richard Bowan, the Install Manager, was there to oversee everything & he did an amazing job. They placed large tarps over all our landscaping & got right to work. Rich kept us updated on progress throughout the day & answered any questions we had. In addition to the new roof, we also had new gutters with leaf guards & downspouts installed. When the work was completed, we walked around the house with Rich. Everything was completely cleaned up; there was nothing left behind or out of place. Our home looks amazing. The new roof, gutters & downspouts really look beautiful. We loved our experience with Home Genius Exteriors, especially working with both Ralph & Rich. They were so professional & knowledgeable. We would recommend them to others & if we needed additional work, we would definitely call Home Genius Exteriors."

"When this pro cleaned my windows, I was not expecting the kind of service I received. My windows are the kind that open to the inside to clean, without having to go outside. This pro did it the old fashioned way because there would be drips. He cleaned outside and then cleaned inside separately. He was meticulous and took great pride in his work. All the sills were cleaned and dirt was removed. On the interior rooms that had a mirror, he even cleaned them! Also, my front glass door looked brand new! I am definitely looking forward to using this Company again in the future. It's evident that pride is taken in a job done to perfection!!!"

FAQs for gutters & downspouts cleaning service projects in Longmont, CO

You’ll want to clean gutters once or twice a year—in early spring and again in fall—to keep water flowing and avoid pricey leaks. Homes tucked beneath tall trees or hit with heavy debris may need two to four visits instead. Staying on schedule protects your roof, siding, and foundation from costly water damage.

Even with gutter guards, plan on an occasional cleaning—just not as often as homes without guards. Installing gutter guards blocks leaves, but grit and shingle granules still slip through and pile up over time. A quick sweep keeps water moving and stops overflow that can damage your roof or foundation.

Watch for overflowing water, slow or silent downspouts, sagging sections, or debris peeking over the gutter edge. You might also spot water stains, weeds, or an increasing number of ants in certain areas. Any of these red flags means it’s time to call a gutter cleaning pro for service before minor clogs turn into major leaks.

Skip cleanings for too long and gutters overflow, sending water under shingles, down siding, and toward the foundation. The result can be mold, rotted fascia, basement leaks, and repair bills that dwarf the price of a quick cleaning. It can also mean that future cleanings will be more expensive as it will take pros longer to deep clean gutters that are full of heavy debris. Staying on schedule saves money and headaches.

Plan on gutter cleaning service to take an average of one hour for an average single-story home and two to three hours for taller houses. Add extra time if gutter guards need to come off or clogs are packed in. Pros work methodically, clearing every linear foot so water can flow freely again.
