   Had my windows cleaned and WOW! I am so pleased. Marlon was thorough and very nice. Did a fantastic job! I will certainly recommend Bren-Mark to my friends. Thanks.

Stella T. |

   Had Bren-Mark do both exterior and interior windows. I never thought my windows were that bad until the job was finished. I was fortunate to have windows that open outward so they did not have to come inside. Both sides were done quickly and efficiently and I was luck to have a beautiful day to open all windows for cleaning. The shining windows made me feel happy.

   From first call to last contact, it was an extreme pleasure to deal with Bren-Mark and their sister company Gutter Gators!  Prompt, polite, informative response to first call--actually VERY surprised to speak with a "human" -- to professional project completion.

A true pleasure to deal with this forward-thinking, customer-oriented business.

Will definitely deal with them and their services in my future home projects!

  If you are looking for a company that has excellent customer service with professional cleaners who are courteous, and eager to please, then call Bren-Mark. You won't be disappointed. They have cleaned my windows for the last three years and the quality of service is consistent.

Wallace J. | Gary

  Would hire again. 

April M. | Westville

  Cleaned all windows (exterior) on a 2-story home and cleaned the gutters of debris. Very well.  I would have them come out again and clean the windows and if necessary, the gutters. Great job! 

William P. | Munster

  I have used Bren-Mark previously and was just as pleased with their work this time. They cleaned all my gutters as scheduled and left behind no mess. Great customer service and responsiveness.

  Many thanks for sending out Josh, Jen and CJ to do my service. They did a great job! Nice, friendly people, too! I am enjoying my clean windows, ceiling fans and mirrors! Everything looks brand new!  

Mary S. | Valparaiso

  I use Bren-Mark Window Cleaning to clean my gutters every Spring and Fall. I LOVE their work. They are prompt and always easy to contact. Two years ago I used them to clean all my windows and screens are prompt and always easy to contact.. I was very pleased. It was as if I was looking through new windows—so clear! I was a bit concerned about tracking in and out of the house while cleaning the screens. No problem—shoe covers were used. I've recommended this company often. I will always use them. GREAT COMPANY!  

Mary A. | Rolling Prairie

  They said they were very busy and it could take several weeks before they could come out. They called back and service was done within a week since they were in the area. Price was higher, but the $50 was taken off and it was the price that we agreed to, so it was fine. They were very professional, neat and clean. Everything was fine and I would absolutely recommend them.  

Alice L. | Hobart

  You guys are amazing! We are so glad you're coming every month!  

Paul – Acme Print Copy Design | Crown Point

  I was at a restaurant yesterday when one of your guys came in wearing a Bren-Mark shirt. A lady there began to ask him about the company. I almost jumped in to tell her how wonderful your guys are. But the young man didn't really need me. He did a great job all on his own. I would have done business with you just based on him. Seems like you've got a lot of right things going on! (*THE CLEANER'S NAME IS MARKO.*)  

Dawn D. | Valparaiso

  Very satisfied with Walter's service. It rained that night but the windows still looked terrific!  

Jenny K. | Munster

  They cleaned the gutters and informed me that the pitch was off in some sections. They proceeded to refer me to a highly recommended gutter company on possibly replacing sections of gutter. Bren-Mark is a very professional service and I plan on using them in Spring to clean my windows.  

Maureen S. | Valparaiso

  The day Bren-Mark came to our house for the cleaning it was extremely cold outside and the windows still tuned out great. The crew was very polite and professional. Very impressed with the service and the quality of work.  

Amy N. | Crown Point

  They were excellent. Their work was very thorough. Will recommend highly!  

Wallace J. | Gary


Mary F. | Chesterton





  We've been using them for years, and always had excellent, trouble-free results. But mistakes can happen--even with the best of us. Let me tell you, I was even more impressed by how Bren-Mark handled a problem: the staff was courteous and very caring, and resolved our issue very quickly. The way they handled my problem puts them waaaay above their competitors, and made me an even more loyal customer.  

Mike F. | Schererville, IN

  The Bren-Mark people are really fantastic. You can count on them to be on time and to do a good job. They have also done window cleaning for me in the past. The young man who cleaned my gutters responded to a problem I told him about by calling his boss and getting a really helpful answer. One of my gutters had a system on it to prevent debris from getting in, but it didn't work. The roofers had put shingles down improperly over that gutter to compound the problem. The owner of the company also works with gutters, has a solution for my problem, and will come and fix it for a reasonable fee. To say that I am pleased is an understatement because I had no idea how to solve the problem and it could have eventually damaged my home.  

Karen L. | Valparaiso, IN

  They came and did it when they said they would.  

Mary G. | Munster, IN

  Very quick response to service call. Fast, courteous and complete work. All this at a reasonable rate. I highly recommend this company! AAA  

Ron B | Valparaiso, IN

  Excellent friendly workers. Did a very good job yesterday.  

John | Griffith, IN

  They responded to my inquiry within 4 hours and came to my house the same day to give me a written estimate of the job. when I hired them, the service person showed up on time and was courteous and professional. She did a wonderful jogb and I would highly recommend Bren Mark. In comparison, price was high, but I was more comfortable because I was told each employee was screened and has had a background check.  

Wendy L. | Highland, IN

  The gentelman was very professtional and did a excellent job  

Dave | Schererville, IN

  They did a great job cleaning my gutters on a high old house that I had a hard time finding anyone willing to do the job at a reaonable price. I highly recommend them.  

Miller Beach, IN

  They responded the same day that I requested service, promptly scheduled estimate, and they did an outstanding job.  

George L | Valparaiso, IN

  “Wonderful Job”  

Bill T | Winfield

   Another great experience!! This is the second time I hired them to clean our windows. Customer service is so professional, prompt and kind. Scheduling was so easy as they had me in there computer already. Technician showed right on time and did an amazing job, once again. They definitely strive to please. I would highly recommend them.

Angel R. |

   Wonderful job!

Cathy P. | Portage, IN

  Outstanding, professional, friendly service. Fast, accurate and fair quotes. The employees have OUTSTANDING work ethic and attention to detail. Having one company service windows and gutters is a fantastic combination! I can't recommend Bren-Mark highly enough!

Tanya L. | Valparaiso, IN

  Superior service from start to finish with office staff, estimate, and window cleaning. Mike was very skilled, extremely professional and personable, and super neat. He explained the process, worked diligently for 3 hrs. plus, and made sure we were satisfied with the job before he left.
We were very impressed with Bren-Mark and have recommended the window cleaning service to all our neighbors within our HOA development.

Gayle & Ron Z. | LaPorte, IN

  Could not have been better. on time, good job, professional, did exactly what they said they would.  

Adam & Nicole | Valparaiso, IN

  Very quick to give an estimate, very courteous, and had several return phone calls. These are super people!! The other 'side' of the company, Gutter Gators, is the one who did the actual work. Very upfront, and very nice. Did a thorough job. Really recommend these people!  

Mike & Phylissa G | Merrillville, IN

  Great company, helped us out in every way possible.  

Sherry | Munster, IN

  Very timely service excellent service great job well done  

Ashley | Michigan City, IN

  They did a fabulous job and it was greatly appreciated.  

Michelle C | Dyer, IN

  I would easily hire Bren-Mark again. The woman who answered the phone was very helpful and pleasant. The estimator came the same day that I contacted them, and the cleaning took place the very next day.  Extremely prompt and courteous!  

Amy H | Valparaiso

  Both my wife and I were impressed with the professionalism and pride that Marlon took in doing the job. He was cleaning our windows when I came home from work, and I was amazed how meticulous he was in assuring the windows were cleaned properly. I mentioned this to him after he completed his assignment, and he told me that he takes pride in his work and always wants to do an exceptional job. I will definitely use the services of Bren-Mark Window Cleaning in the future, and will certainly request that Marlon be the person sent out.  

Greg M | Dyer

  They cleaned my gutters after the winter. A week later, when I though there was a problem with my gutter that they might have caused, the owner came out to inspect. It turned out that a recent severe storm had created a blockage with new leaves. He cleaned it out but didn't charge me. They have great customer service!  

Sarah M | Chesterton

  They washed all of our windows. The work was completed will care and concern toward needed results. Excellent job!!!!  Would use them again and the worker was great  

Gary E | Valparaiso

  I had an estimate done for gutter cleaning, gutter leaf covers, and window cleaning (to remove smoke residue from previous owner).  There was a little bit of confusion about the date and time of the estimate, but it all worked out well The owner came himself and provided me with an estimate.  By accident, one of the ladders broke a window in the porch.  The owner not only cleaned up the broken glass, taped up the window, and called a referral company to have the window replaced at his cost.  He was very polite, professional, and apologetic.  He even cleaned my gutters on the spot at not cost to me because he felt so badly about the broken window.  He provided excellent custom service.  I am having them back out to clean my windows in a few weeks!  

Kiristen B | Highland

  Responsive, reasonable, punctual, courteous, efficient and professional, Brian did excellent work at our two story home with no inconvenience to us.  Because of its excellent work I highly recommend this window cleaning service. I had what I considered to be a reasonable estimate the day after I contacted Bren-Mark and Brian came to our home on the morning of May 10th, on time and as scheduled.  We went over the work to be performed and he then went to work.  I had absolutely no complaints and he earned our compliments..  

J K | Munster

  From start to finish, it was a friendly and professional process.  I located this company in an ad in the Times.  I called and made an appointment for an individual to come out and give me an estimate.  He showed up on time, was friendly, and gave me a reasonable quote for their services. I scheduled for the work to be done that day.  On the day of work, the cleaner, Marlon, was on time, extremely friendly, and described what he would be doing, and what I could expect at the completion of the job. I must shamefully admit our windows had not been properly washed for several years.  We live in a two story home and I find it harder and harder each year to climb the ladder up the higher windows. When Marlon finished, I was absolutely amazed at how clean the windows, window sills, and screens were.  No streaks either!!!  Great job Marlon! All in all, it was a wonderful experience.  I have already scheduled another wash in late Fall.  I highly recommend Bren-Mark to any one needing this type of service.  

Wallace R | Highland

  This is a wonderful cleaner to do business with. No Mess, no problem. Showed up when they were appointed. Would recommend to anyone  

Paul S | La Porte

  They washed all the windows in my two-story home.  It is a large home with lots of windows. They put on booties to come inside and they were friendly, polite, and respectful the entire time they were here.  They did an excellent job on my windows, better than I could have done myself.  I would highly recommend them.  

Claudia D | Munster

  Good Service, Quality of work is well done.  Definitely would ask them to come back. Planning on having more work done during the summer, Service came promptly.  Procedure was explained and estimated time of completion was discussed.  

Denise S | Valparaiso

  The initial phone call to Bren-Mark was answered promptly and professionally!  My quote was left on my door within 48 hours and when I scheduled the appointment it was scheduled within 48 hours.
Marlon arrived on schedule, he was polite and introduced himself, he was also wearing a coat with the company name on it.  He started work immediately and stayed until all my gutters were cleaned.  The perimeter of my house was clean, all leaves and debris was bagged and he asked where he could leave them.
After the job was complete, I received a call from the office to see how the job went and ask if I could be put on their call back list, which I responded with a definite YES!
Today, I will be calling them back to get a quote for the company I work for.  

Linda S | Schererville

  I had all my double pane windows cleaned (18) including all the screens and my sliding patio door. I also had my gutters cleaned. The windows look as clear as they did when the house was built 35 years ago!! I will always find the money to pay to have the gutters cleaned. The young men that preformed the work were very professional and friendly.  I like that they put on shoe coverings when working in the house. I will always use this company.  

Mary M | Rolling Prairie

  I have about 55 windows, some of them are very high. They have been doing work for me for 3 or 4 years. They do a good job.  

Joan H | Culver

  They responded promptly to my request for window washing.  Everything was handled professionally and I was impressed at how easy it was to get set up.  Windows looked wonderful-exceeded my expectations.  

Tracy H | Valparaiso

  This was no small job! Staff on time, at a minimum 300 linear ft. of gutters cleaned out after never being cleaned for years-job completed by two brave staff at Bren-Mark. I would bring them back for maintenance now that I have the cleanest gutters in town! The office staff was great to work with-I asked a few questions and called a couple of times to insure I was getting what I needed and everyone was helpful. Great team effort!  

Sandra A | Valparaiso

  They were completely professional, were punctual and friendly, and very experienced.   They did the whole job in about an hour and 15 minutes (there were two of them).      The windows were completely clean when they left.  We had had other window cleaners that we had liked who charged a little bit less, but they are not performing that service anymore.   They did not do as thorough a job, and it took them longer.   I am completely satisfied with Bren-Mark and will hire them again.   They were recommended to me by a friend who works for a local business;   they also clean windows for commercial establishments.

  Melanie called gushing about Jen’s service; said she was so tickled with her…excellent  service…talked, but not too much. Paid attention to her work and did a wonderful job. Windows are beautiful and sparkling!  

Melanie S. | Demotte

  This company did a great job. My gutters had been very neglected…Since their schedule was very full, they told me that they were scheduling jobs between other jobs in order to service all orders. Nevertheless, my gutters were cleaned witin 2 days, which was sooner that I thought. Will definitely use them again!  

Erica G. | Merrillville

  Company responded quickly, sent someone out for estimate and scheduled service in very prompt manner. Workman was thorough and did a meticulous job.  The gutters were packed and he cleared completely and hauled all debris away. Very pleased with work  

Robert S. | Griffith
