Joslin-Co Window Cleaning

Joslin & Co Window Cleaning is a family-owned, owner-operated business — Nico Joslin started it in New Ipswich, NH in March 2024, and in a little over two years has built a route across southern New Hampshire and north-central Massachusetts, from Nashua and Concord down to Leominster and Fitchburg. All 31 reviews on file, across Google and Thumbtack, are five stars, with 28 of them landing in just the past six months as the client list has grown. Commercial accounts are a big part of the pattern: a Leominster business owner has him out monthly, a Concord coffee shop and office both describe repeat visits, and one recent reviewer said they were already under contract for further service after their first appointment. On the residential side, reviewers in Salem, Keene, and Leominster describe the same routine — on time, thorough, and clean windows. Thumbtack's listing shows the work goes beyond windows to gutters and solar panels; in a 2025 review, one customer described having him clear debris off their solar panels, though they hadn't yet seen a clear output improvement. Thumbtack also lists a completed background check for Nico Joslin. This fits homeowners and small businesses in the Nashua–Concord–Fitchburg corridor who want a recurring window-cleaning routine, with gutters or solar panels added if needed. With no negative reviews on either platform yet, the main thing to sort out is simply scheduling and pricing for the property.
