HAD been using Bren-Mark for 3 years, 2x / year. Called them the morning of Monday June 9, 2025 to set up an appointment. Was told 2-3 weeks. As other reviewer noted, they never give a day nor notify you they are coming the next day or on the way that day. They send a "Thank You!" card and receipt for $356 in mail which I received on Wednesday July 9, noting that they were there on Wednesday July 2, 2025. That was the first time that I had heard from them since 6/9/2025, as I did not see them at my house on July 2. The afternoon of Wednesday July 9, 2025 there was an afternoon downpour and I saw one the gutter over one of the downspouts overflowing like a toilet over the top on the second story, no water coming out of the bottom of the downspout at all. These are straight-line gutters leading to a downspout at the end; no complicated connections. I called Bren-Mark that afternoon and again the next day Thursday July 10 to explain the situation. They emailed pictures of a guy's legs / feet near some of the gutter areas. I emailed back to note which area of the end of the gutter/downspout I was talking about They never said whether they even checked the downspouts in the first place, never mind put a blower or small drain snake down them. I said that I needed them back right away as there was more rainstorms in the forecast soon. Never heard back / never saw them. On Monday July 14 I called another contractor in Highland gutters where the owner is the person who actually shows up to do the work, and a much lower price than Bren-Mark. They came gave me a set date and set 2 hour time window, which was early afternoon today Wednesday July 16 on the early side. They completely cleaned out that downspout, (which was BLOCKED SOLID with leaves and maple tree helicopter seeds) and the others, and checked / blew out the rest of the gutters. So I emailed Bren-Mark to not bother coming back. Sure enough, an afternoon downpour came this afternoon and had no problems; nothing over the gutters, downspouts flowing freely. Also found out that one of my recently installed bathroom fan roof vents was stomped on - probably from Big Foot, right? Anyway I a one star review here is way too generous for this service, price and quality. What a way to kiss $700 / year good-bye, forever! I am done with them.

I hired Bren-Mark Window Cleaning to clean the windows of my 2 story 3 1/2 bedroom home which hadn't been cleaned in years. I'm the owner of the highest rated window cleaning business in Los Angeles, California and was looking to hire someone in NW Indiana who also does the best quality work. They did a beautiful job! The final charge came in less than the estimate! I called two other companies. One estimate from a guy Steve was much higher and the other company never returned my calls. Take it from a 25 year professional. Bren-Mark is the company to call. read more

I hired Bren-Mark Gutter cleaning to fit my gutters with leaf guards and put a heat wire in an area where I have a flat roof. All this work was done in one day and I am very pleased with the results. I highly recommend them if you have this type of work needed. They are very experienced and will go over any questions you have. The gutter guards I purchased were quite reasonable. I plan to tell my friends and neighbors about Bren Mark if they are needing this type of work done. read more

We just got our windows and gutters cleaned and everything looks awesome. Luke and Mike serviced our house and they were not only polite and sweet, they were also great workers. The wait to get the cleaning scheduled was a little long, so please call early. That is only a testament of how good these guys are. See you next year Bren-Mark and honestly, you have (2) gems with Luke and Mike. read more

Quickly came out to give an estimate. Offered a "senior" discount. No long wait for an appointment. Kyle showed up on time and worked meticulously all day on a miserably cold, windy day. It's a big house with lots of windows and he was as thorough with the last one as he was with the first. If all the employees are as compulsive as Kyle you will be well satisfied. I sure was. read more

Great, friendly reliable service. We have been using Brenmark at our home and businesses for years. They will set you up on a schedule and show up regularly. The windows are great.... One less thing you have to worry about! read more

I just had my windows cleaned inside and out by Josh of Bren-Mark Window Cleaning and Wow! what a great job! I for one have never thought about having someone clean my windows as I like to take care of these items but with time constraints, it's better to call the professionals. I now look forward to using this company twice a year (April and September). Thanks again! read more

I can't say enough about how great my windows look. Reasonably, I shouldn't need to hire someone to clean my windows given my windows all tilt in and I'm an able human - but we built our home and have lived here for 10 years and they have never been cleaned thoroughly before. These guys, Wyatt and Lucas, couldn't be more polite with complete attention to detail. From top to bottom, they did all of my windows, inside and out, all the sills and screens in less than 4 hours and I am so happy. Meticulously done! read more

Used them for years, but suddenly, they will not allow you to make an appointment! They want to come whenever they want, even if you are not at home! They would not even agree to give me a call on the morning of the visit! How do I know they washed all of the windows? I have many things outside - what happens if something goes missing? read more
