Janitorial and commercial cleaning leads in New Hampshire

Manchester is the largest city, and its Millyard, a row of converted mill buildings on the Merrimack River, now holds tech firms, offices and university space. Downtown has banks, law firms and Elliot Hospital and Catholic Medical Center close by. Nashua, just to the south, has office parks, defense and electronics manufacturers and retail along the Daniel Webster Highway. Both cities have many mid-size employers who manage their own cleaning contracts, so the office or facilities manager is usually the right contact.

On the Seacoast, Pease International Tradeport, on the former Pease Air Force Base in Portsmouth and Newington, holds office, industrial and lab space for a long list of tenants, including biologics manufacturing. Downtown Portsmouth has restaurants, hotels and small professional offices that stay busy all summer. Across the river in Kittery, Maine, Portsmouth Naval Shipyard brings contractors and suppliers to the area. Dover, Rochester and Exeter add smaller commercial centers.

Concord has the State House, state agencies and Concord Hospital. In the Upper Valley, Dartmouth College in Hanover and Dartmouth Hitchcock Medical Center in Lebanon create a medical and academic market out of proportion to the region's size. The Lakes Region and White Mountains lean on hotels, resorts and ski areas. In 2023 New Hampshire had 373 janitorial services establishments employing 2,928 people, a small supply for the number of offices and plants in the southern tier.

What changes through the year

New Hampshire gets four hard seasons. Winter snow and salt run from December into March, and mud season in April tracks dirt into every building. Fall foliage season fills hotels and restaurants in the White Mountains and Lakes Region, and ski season keeps them busy into spring. On the Seacoast, Portsmouth and Hampton Beach see their heaviest restaurant and hotel traffic in summer.
