Modular Concepts provides commercial building cleaning across Massachusetts, Connecticut, and Rhode Island from our Marlborough headquarters. One monthly program covers the lobby, shared restrooms, corridors, stairwells, and the dock. A suite joins the same quote only when its occupant asks, on its own line. Service is month to month, with no long-term contract.




Commercial building cleaning covers the shared interior of a multi-tenant property: the lobby, the elevator bank, the corridors, and the shared restrooms. One floor plate may hold offices, a clinic, and a service business, and they all use that shared space. Modular writes the shared scope first, so every visitor walks into a cared-for building.
Common areas take the hardest traffic at the address. Couriers, patients, and every firm's staff use the same entry and the same restroom stack. Those areas are the base program. A suite joins only when its occupant asks, and it is priced on its own line.
Each visit ends with a sign-off for the property contact, ready to read the next morning. Property management teams get one page to forward when an occupant asks what was done.
| Line on the quote | What it covers | Billed to |
|---|---|---|
| Common areas | Lobby, corridors, stairwells, elevator cabs, shared restrooms, and the dock | The property |
| Optional suites | A task sheet per suite, added only when that occupant asks | The occupant, or the property if you prefer |
| Project work | Floor refinishing, pressure washing, and cleaning after a fit-out | Quoted per project, as separate lines |

Shared commercial buildings are harder to keep clean because the occupants keep different hours and nobody inside owns the hallway. A clinic opens early. An office hosts evening clients. The dock takes deliveries at midday. One crew plan has to respect all three.
Access and billing come first. Modular walks the common areas with the property manager and writes down which areas are on the program. Keys, fobs, and alarm notes are set for each entrance before the first night.
Tenant turnover never stops in a shared building. A firm leaves, a suite sits empty, and a build-out fills the hall with dust. The program flexes with each change. There is no new contract to sign.
Foot traffic concentrates on a few paths. The lobby glass, the elevator buttons, and the busiest restroom stack need more passes than a quiet back corridor. The scope puts the time where the traffic is.

Property managers pick Modular for three main reasons: month-to-month service, a certificate for each address, and one contact for the property.
Service is month to month. Nights change when a firm leaves, and there is no term to unwind if the building sells. Customers stay about eight years on average because of the work.
Coverage is $2,000,000 in general liability through Northeast Insurance. Workers' compensation is through Travelers. The property and the management company are named on the certificate.
Shared areas, optional suites, and project work each sit on their own lines. When an occupant asks who mops the hall, the answer is on the written scope.
Background-checked people are assigned to the address. A supervisor inspects on a schedule and walks the lobby path first.
Modular is certified by the Massachusetts Supplier Diversity Office. That helps properties and occupants that spend state funds meet their vendor rules.
Crews are Green Seal trained. Low-odor products are available for floors that are occupied early or late.
Each program has its own service page. Each one is its own line on the quote.
Package piles, wet entries, and a busy restroom cannot wait for the night crew. A day porter keeps the entry glass clear, checks the shared restrooms at set times, and keeps the package room passable. The porter reports to the property manager, and the hours follow the building's traffic.

Shared corridors wear faster than any one suite. Modular's floor care program covers 750,000+ square feet a year, including carpet cleaning. VCT and tile run on a scrub and burnish rotation set to foot traffic. Strip and wax is done on a weekend, so the hall is dry before Monday. Hard surfaces only. No wood refinishing and no concrete polishing.

A suite build-out leaves dust in the shared hall as well as the suite. Modular cleans both after the trades leave and before move-in. The work is quoted as its own project, so the monthly program and its invoice stay the same.

The walk to the door is the first thing a visitor sees. Pressure washing lifts winter salt, gum, and dock grime from concrete and pavers. Modular schedules the work off-hours and around deliveries. It is quoted per visit, apart from the monthly program.

Five steps from the first walk to the first change in occupancy.
The lobby, each restroom stack, the stairs, the dock, and one sample corridor. About an hour with the property manager, during business hours.
Common areas go on the base quote. Optional suites and project work are listed as separate lines.
Keys, fobs, and alarm notes are written for each entrance. The certificate names the property and the management company.
Each visit closes with a sign-off for the property contact. A supervisor inspects on a schedule.
Nights and porter hours move when a firm leaves or a new one opens. No contract has to be reopened.
Commercial building cleaning is priced per building after a walkthrough, not from a posted rate card. Modular Concepts quotes the common areas as the base program and each optional suite as its own line, month to month, across Massachusetts, Connecticut, and Rhode Island. Three things set the monthly number: the areas in scope, how often each one is cleaned, and the tasks each visit covers.
About an hour with the property manager. The lobby, each restroom stack, the stairs, the dock, and a sample corridor. Every shared area gets its own line on the quote.
Shared areas are the base. A suite is added only when its occupant asks, so the property never carries a cost it did not choose.
Nights per week are set area by area. A lobby and a busy restroom stack run more nights than a back corridor, and porter hours are priced by the hour.
The task list follows the area. Restrooms and lobbies carry the longest lists. A stairwell is sweep, spot mop, and rails.
Areas, frequency, and tasks become lines. Common areas, each optional suite, and project work stay apart, so each party pays only for its own space.
Steps advance on their own. Tap a hex to hold it.
Ask your current vendor for the task list and bring it to the walk. Modular prices the same areas so the two quotes line up row by row.
Modular Concepts cleans commercial buildings with shared interiors that a property manager has to keep, across Massachusetts, Connecticut, and Rhode Island. That runs from a two-story professional building to a flex building with a loading dock. If more than one firm shares a lobby, a hall, or a restroom, the building belongs on this program.
Offices over other businesses, with one lobby. The shared lobby, halls, and restrooms are the base program. Each firm upstairs can add its suite.
Several firms and one manager. The landlord carries the entry, the corridor, and the shared restrooms. Each firm decides whether its suite joins.
The lobby, the shared corridors, and the public restrooms are on this page. Exam rooms and clinical suites follow the medical program, with their own scope and their own line.
Flex and service buildings with a shared receiving area. The dock and the service hall join the program when more than one occupant uses them.
One main user plus shared support rooms. Every floor sits on one scope. A cafeteria hood can be added as a licensed visit.
Two or three buildings under one manager. Each address keeps its own scope and its own certificate. The property keeps one Modular contact.
Full-facility retail is outside this scope, so a store inside the building keeps its own vendor. A restaurant can add licensed kitchen hood cleaning. Dining rooms and restaurant restrooms stay with that restaurant. A building that is all offices is covered on the office buildings page.
These are real Google reviews from customers in buildings Modular Concepts cleans, quoted as written. Ask us for property manager references on a building like yours.
“Luiz and his team of cleaners have been cleaning our two business locations for the past 3 years. We have been happy with the level of cleaning. He reaches out often and even stops by to make sure our buildings look great and that we are pleased with their cleaning!”
“Luiz is a true professional business man and a pleasure to work with. Modular Concepts does a great job cleaning all 3 floors of our space and the day porter he provided does a wonderful job every day. We love her!”
“Our companies experience with Modular Concepts has been consistently spectacular since taking occupancy in a high traffic, busy building in Marlborough. This is a rare quality to have in the services industry, and I wish we could use his services in every one of our clinics.”
These answers are for property managers. A firm that only needs its own suite cleaned can start on the office cleaning page.

Commercial building cleaning includes the shared areas of the property: the lobby, corridors, stairwells, elevator cabs, shared restrooms, the mail room, and the dock. Those areas are the base program, billed to the property. A suite is added only when its occupant asks, and it is priced on its own line. Day porter hours, floor care, and cleaning after a fit-out are separate lines as well.
Commercial building cleaning is the program for a shared address, while commercial cleaning is the nightly service itself. Modular's building program starts with the common areas that several firms use and adds suites only on request. The commercial cleaning page explains the nightly method. The building program adds the scope split, the billing lines, and the access plan for one address.
No, Modular does not clean stores or stockrooms, because full-facility retail is outside our scope. A shop inside the building keeps its own vendor. Modular cleans the shared lobby, halls, and restrooms around it. If the shop's customers use the common restrooms, those restrooms stay on the building program and a day porter can check them.
Yes, one Modular quote can cover occupants with different needs in the same commercial building. The common areas are the base program. Each suite that opts in becomes a separate block on the same quote, with its own nights and its own task sheet. Each block is billed to whoever you name. When a firm leaves, its block drops off and the rest of the quote stays as it was.
The property and the management company are named on the certificate of insurance for each address. General liability is $2,000,000 through Northeast Insurance. Workers' compensation is through Travelers. A portfolio gets one certificate per building, and a copy is available on request before the first visit. Everyone placed on site is background-checked.
A restaurant in the building can add licensed kitchen hood cleaning, which Modular schedules as its own visit. Dining rooms, front-of-house areas, and restaurant restrooms stay with that restaurant's vendor. The shared lobby and the hall outside the restaurant remain on the building program, so the entrance is still cleaned on every visit.
Yes, Modular can clean during business hours with a day porter. Night cleaning is the base program for most commercial buildings. A porter covers the lobby, the shared restrooms, and the package room while the building is open. Porter hours are a separate line, so you can add or drop them as traffic changes through the year.
Yes, Modular cleans commercial buildings in Connecticut and Rhode Island as well as Massachusetts. Headquarters are in Marlborough, Massachusetts. Crews also serve the Hartford and Providence markets, and each building gets its own certificate. A manager with addresses in more than one state can keep one contact and one quote.
Property managers often run these alongside a commercial building. Each has its own program.
