Great company. Trustworthy staff, and owner. They don’t cut corners, or take short cuts. When Sparkling Concepts cleaned my house’s windows, I was really impressed. They were respectful of my house, did the job right, and in a timely fashion with the right tools. They do both commercial and residential cleaning. I’ve seen they’re guys cleaning storefronts all around NH and MA. The website details that they are certified members of the IWCA and have full insurance. I wasn’t disappointed. You might think ‘why would I need my window’s cleaned?’ But, after they did my house, I saw a huge difference. Where I live we get REALLY bad pollen; Sparkling Concepts pulled out all of our screens, carefully scrubbed them, and sprayed them down individually. Afterwards, they brought them back in the house and reinstalled them in the right places. They’re owner really understands customer service and professionalism. I like his staff, and the job they do. Great company.
