Adrian and Luis were exceptional. I researched so many companies before I picked one to replace my battered exterior french doors and large single hung window. I needed extra security in these plus they started just falling apart. Other companies tried to up sell me, quoted double yes double the price and then two others from another company just stared waiting for the boss. I mention what happened before ALCO got the job because I was in despair. When they came in, they presented themselves as professionals, were neat, organized, discussed options and gave a written estimate which they stuck to. In fact, they were the ONLY company that bothered to board up broken window panes for me...free. It was a wait for the materials but they prepared me for that and managed to even get them on time in hurricane season. Anytime I called or texted, they answered me quickly. They never got annoyed with the smallest question. Today was the big day. I figured it would take about 1 1/2 days with all the work to do..They finished in about 3-4 hours. The french doors look beautiful (measurements were exact) and the extra locking security on them was just as promised. The window was a breeze too. There wasn't a speck of dust in my room where the doors exited to the outside. Cosmetically, even the caulking was a clean line. No breaking of concrete or any problem. They offered to come back even if the caulk retracted! They threw the garbage out for me including the glass and it was cleaner when they left than before. The money. They got the deposit, recorded carefully, explained everything to me. When the bal. was paid, same thing. Absolutely not even the cost of a screw was added. I would say it was a fair price for the work but actually it was better than that as I had peace of mind with them here.I didnt want to tell them but actually they were the best estimate I got too. So, as they were leaving, I looked at my front windows (I have a mountain of windows back and front). I asked and yes, I am going to start by replacing the front ones first with more impact glass. Usually i m glad when workmen leave but they were kinda light hearted and Ill be looking forward to working with them again.Adrian and Luis are highly recommended for any window and door issues you have. Thanks Alco !!
