Griss Maid Services is also a sister company of Baiza Construction both of which I had utilized over the course of a couple years, most recently this month. So far, I have had 5 visits/assignments with Griss Maid Services and Baiza Construction, soon to be 7. The ladies with Griss Maid and the gentlemen with Baiza are exceptional-- extremely polite and professional. With both companies the crew did a wonderful job in a university rowhouse rental where students' hygeine should be required but not guaranteed and thus were a life saver. I have tried other groups such as Merry Maid, the neighbor's regular cleaning lady, etc... but felt they were by far much better. For example, when when vacuuming a room, shoes and stools should not be placed on a bed to vacuum the floor because it dirties the bedding. They are reliable and one does not have to question methods of effective cleaning because they do a thorough job the correct way. I called upon them again not only for organizing and cleaning which they did a fantastic job the first time, but also for building a room enclosure in which they moved a wall and a support beam - knowledge of weight bearing support beams and where to place them is one of their gifts (where most would be apprehensive), installed a shower and vanity to an existing bath, and a new bathroom floor. Their plumbing skills is also another area of gifting esp since all other contractors/plumbers (licensed) are apprehensive to work on historic properties because the plumbing material,layout may have been outdated, so on and so forth. Mr. Guzman is knowledgeable on the historicity of plumbing and knows what will function and what will not. He and the team on both crews possess an inner confidence that exudes from a deep understanding and devotion. In both organizing, cleaning, and building Mr. Guzman and team are problem solvers and get near impossible and/or difficult jobs done (where most say no, it cannot be done) in shorter than expected time and think it was no big feat. I was/and am so pleased with everything- the finished product, the timing and their professional manner and level of skill. I honestly would not call another group unless I absolutely had to because I trust their level of knowledge. They handle every situation so that the outcome turns out wonderfully and beautifully.
