I do not believe they're using the term "right way" in the conventional sense, so I wanted to ensure that would-be clients are aware of their semantic approach. > > Based on the experience hiring Alco to complete my deck project, the "right way" apparently involves: > > \- Assigning a disinterested, rude, and over-worked project manager who will rarely visit to check on progress/quality of the work. He will, however, be prompt and proficient at taking payment. > \- Failing to ensure that railing posts are plumb and then telling you it's "too late" to fix it when you point it out. > \- Messing up the Cortex plug system to the extent that they'll then need to paint the entire deck trim to cover up holes, bulges, and other imperfections. > \- Using interior wood filler and interior paint on said deck trim, which promptly starts peeling after the first rain. > \- Promising to come and fix the peeling paint and crumbling wood filler, but never really intending to do anything about it. > > I tried to give these guys the benefit of the doubt, as they stepped in to the project mid-way. I reached out to one of the owners of the company for over a month trying to get them to repaint the peeling trim and I've been blown off consistently. I'm giving them two stars because they did finish the deck, but I can't imagine hiring them for another project. **Comment from Alco Products Inc:** > Dan, > > I am very sorry that your project did not go smoothly with us. We are a family owned and operated business and we take great pride in our work, and feedback like this is not the norm us. We take every customers feedback, good or bad, very seriously, and again, my apologies. > > It was my understanding that we had completed all of the touchups and punch list items requested, but I am having someone from my production team reach out to you to see if there is anything we can still do to resolve the issue. > > If you would like to discuss this further, please feel free to give me a call at 301-593-1691. > > Thanks, > > Jesse Kreisman **★★★★★ — Alex Tonetti, Aug. 2019** > I had all of my windows and doors replaced by Alco, they did a beautiful job and did it for a fair price. The workers were extremely nice, professional and cleaned up after themselves each and every day. The job was done on schedule and for the agreed amount. NO surprises! The folks over at Alco made the whole process easy. I didn't have to worry about anything. Highly recommend!!! **Comment from Alco Products Inc:** > Alex, > > We are glad to hear you are satisfied with everything. Thanks for the opportunity to work together. > > Best, > > Alco **★★★★★ — Nadine Costello, Dec. 2018** > Great company - a key member of our remodel team. The team at Alco embody professionalism. We continue to recommend them to our friends and neighbors, and will use them again for future projects. From start to finish communication was great - the team was always professional and we never had any unanswered questions or concerns. The work is beautiful and flawless - the new siding, trim work, new roof and windows look great. Alco brought our vision to reality and we couldn't be happier! We get regular compliments from our neighbors and strangers alike. As far as our experience is concerned, you can't go wrong with the team at Alco! **★★★★★ — Diane Nicholson, Dec. 2018** > Alco did an incredible job with my roof installation. The crew was very professional and they cleaned up well. The roof looks great and I'm very pleased. I highly recommend Alco! **★ — Jeanne Haggerty, Dec. 2018** > My experience with Alco was horrible. I would never use this company again. The window was delayed, took much longer than expected and the professionalism was non-existent. I was actually insulted multiple times by Scott, the project manager, and charged for work they did not end up doing because they kept getting things wrong. And when I expressed dismay I was both insulted and dismissed. **Comment from Alco Products Inc:** > Jeanne, > > I am very sorry that the project did not go as you expected. At Alco, we strive for 100% customer satisfaction, and I would love to be able to discuss this further. If you would, please give me a call when it is convenient so I can see if there is anything we can do to remedy the situation. I can be reached at 301-593-1691. > > Jesse Kreisman **★★★★★ — Ruth D'Alessandro, Nov. 2018** > After checking out several different types of windows over a two year period, I chose to purchase 17 Marvin windows and a storm door through ALCO. I was considering another company with Marvin windows in Fairfax, VA, but they kept changing the price. When Shaun T. came to my house, I liked him immediately and he took pictures, notes and listened to what I wanted. When I went to the office, he introduced me to the team which had been in business for 30 years and was family owned. I was impressed with the professionalism and friendliness of everyone I met. They liked each other and were happy at work I thought the prices were very reasonable there were no hidden costs. Jeff, Spencer and Rob installed my windows and storm door in 2 days. This was August of 2018 which were the hottest days of the year. They were very considerate of and worked so that I could put my cats in one place while they completed the majority of the work. In addition to being unbearable hot, they had to install windows on 4 levels of my townhouse. ALCO has been the best company I have ever dealt with and I plan to use them again for kitchen and bathroom renovations. My family, friends and neighbors have all made positive comments about my windows and door. My neighbors could not believe how quickly and efficiently they worked. My sincerest thanks again to all of you. **★★★★★ — Mark Dorf, April 2018** > I had a wonderful experience with Alco Products. They did all my window replacements and my french doors to my deck. No more drafts! From Zak right down to his crew they were all very courteous and very prompt. > > I was surprised how fast they did my windows. > > And unlike other experiences with contractors that made and left a mess, Alco's crew were extremely tidy. > > I would highly recommend hiring Alco Products for your home improvement needs. **★★★★★ — kayandjim15, Dec. 2017** > We are very pleased with our new siding. The workmen were very meticulous with measuring and installing. We were very satisfied from the estimate to the finished project. **Comment from Alco Products Inc:** > Thank you for the kind words. We are glad you are happy with everything! **★★★★★ — Harry C, Dec. 2017** > The window installation process was easy and painless. ALCO Products installed 5 windows in 3 hours and did a great job cleaning up after the job. The customer service from the team was outstanding and use them again in the future. **Comment from Alco Products Inc:** > Thank you for the kind words. It was a pleasure working with you. **★★★★★ — Jeffrey Lowe, Oct. 2017** > We couldn’t be happier with Alco. They came to give an estimate right away, knew exactly what we needed, and did a great job. An excellent experience from start to finish. Highly recommended. **Comment from Alco Products Inc:** > Thank you for the kind words. It was a pleasure working with you. **★★★★★ — Nancy Trevor, June 2017** > I have used this company for over 20 years. I have been satisfied with every project. The management and sales force is not high pressure , which appeals to me. I comparison shop, but I know I will always get a fair price with ALCO so I call them without hesitation. My latest project was a storm door and again I am pleased with the results. **★★★★★ — Amanda Eisenberg, June 2017** > Zak and team are extremely friendly, professional, and punctual. Most of our windows were custom jobs and Zak was great at figuring out the right solution for our non-standard openings. Due to the size of the job we split it between four visits, which also gave us time to ensure the custom solution would work on all windows of those sizes. ## Selected projects - [Arlington, Va.
