Katis Cleaning Service - Residential, Commercial, House

Katis Cleaning Service, run by Katia and a small team out of Windham, has built its track record almost entirely on repeat customers rather than one-off jobs. Several 2023 reviews describe clients who'd already been with Katia for years by that point, and a 2026 review says the same thing from a customer of about two years: never disappointed, calling the team trustworthy at all times. The company's own site describes residential and commercial cleaning, covering both one-time deep cleans and a regular cleaning schedule. The specifics in these reviews lean heavily on thoroughness. A 2025 review of a deep clean called the attention to detail second to none, and another from 2025 describes every corner of the house left spotless, down to items that were moved back into place afterward. One reviewer who'd tried other cleaning services first said those had been rushed or unreliable, and contrasted that directly with Katia's team being thorough, kind, communicative, and reliable. Another, going through shoulder and knee recovery, said Katia worked with her on a flexible schedule during a difficult stretch. One client liked the team enough to ask them to keep cleaning after a move from Windham, NH to Andover, MA, and the team agreed. A Portuguese-language review from mid-2025 also praised the team's work and said the customer was very satisfied. There isn't a documented complaint anywhere across the reviews here — all 11 on file, spanning 2023 through 2026, are five stars. For a homeowner in the Windham/Salem, NH area looking for a cleaning service they can stick with long-term, the consistency of years-long client relationships is the strongest thing this evidence shows.
