Tour traffic hits the lobby first. That means entrance glass, elevator cabs, corridor carpet, and stairwells. Suites can share the nightly visit or keep their own nights. A sign-off goes to the building contact the next morning.
| Scope | What it covers | Billed to |
|---|---|---|
| Building scope | Lobby, elevators, corridors, shared restrooms, stairs, and the dock | The building |
| Tenant scope | A task sheet per suite. Nights follow that tenant. | The tenant, or rolled into the building invoice |
| Add-on lines | Day porter, floor and carpet programs, and window cleaning, added only when the building asks | The building, as separate lines |
Office buildings are different to clean because the building never fully closes, access rules change by floor, and the lobby carries every tenant's traffic. One tenant starts at 7 a.m. Another hosts clients at night. The lobby may stay open for a fitness room. The crew works around all of that.
Access is the first constraint. Fobs, alarm zones, and elevator rules change by floor. Crew names belong on the building security log, not only on a tenant list.
Hybrid floors sit half empty on Friday. Lobbies and shared kitchens get busier. Kastle's badge data put average office occupancy at 56% of the 2020 baseline in October 2026, with a Tuesday peak near 66%. An old scope over-cleans empty suites and under-cleans the lobby. Modular reviews zones on a set rhythm and moves nights toward the traffic.
Winter salt lands in the vestibule first. Mats and a nightly mop keep a Class A lobby from going dull by February. Entry care is on every office building scope from November through April.
Property managers pick Modular for an office building for three reasons: month-to-month service, a certificate per address, and the same crew every night.
No annual janitorial contract to carry through a sale or a lease turnover. Customers stay about eight years on average because of the work, not a term.
Coverage is $2,000,000 in general liability through Northeast Insurance. Workers' compensation is through Travelers. The owner and the manager are named on each certificate, and a copy is available on request.
Zones and tasks sit on one page. When a tenant asks what the building pays for, the answer is that page.
The same background-checked crew returns. A supervisor inspects on a schedule. The visit note is in before the lobby opens.
Modular is certified by the Massachusetts Supplier Diversity Office. That helps owners and tenants that spend state funds meet their vendor rules.
Crews are Green Seal trained. Low-odor products are available so an early tenant does not smell the night work.
Each program has its own service page. Each one can sit on the building invoice.
A busy lobby usually needs a person on site by day. Restrooms get checked. Conference rooms reset between meetings. Spills are handled while tenants are in. The porter reports to the property manager.
Lobby and corridor floors take the whole building. 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. Strip and wax is scheduled on a weekend so Monday opens on a dry floor. Hard surfaces only. No wood refinishing and no concrete polishing.
Office carpet shows the path to the kitchen before the quiet edges look dirty. Hot-water extraction hits entries and wear lanes. Low-moisture work holds the rest. Both are timed so carpet is dry before doors open.
A new suite ends in dust. Modular cleans it after the trades leave and before move-in. Entrance glass can be added so the first tour reads clean. The project is quoted on its own. The monthly building scope does not change.
Five steps from the first walk to a zone review.
Common areas, a sample suite on each floor, the dock, and where crews park. About an hour, during business hours, with the manager or the engineer.
Building lines and tenant lines on one quote. Nights per zone are listed. Day porter hours are listed only if you want them.
A certificate names the owner and the manager. Fobs and alarms are set per floor. Crew names are on the security log before night one.
Each visit closes with a sign-off. A supervisor inspects on a schedule. Unusual items reach you before the building opens.
When occupancy shifts, nights move. Seasonal carpet and entry-floor work is booked before it becomes a complaint.
Office building cleaning is priced per building after a walkthrough, not from a posted rate card. Modular Concepts quotes the building scope and each tenant scope as separate lines, 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 manager or the engineer. Common areas, a sample suite on each floor, the dock, and where crews park. Every zone gets its own line on the quote.
Each part of the office building is its own zone, so the owner and each tenant see only their own space on the quote.
Nights per week are set zone by zone. Busy common areas run more nights than a hybrid suite, and a day porter is priced by the hour.
The task list follows the zone. Restrooms and lobbies carry the longest lists. A corridor is vacuum, spot, and trash.
Areas, frequency and tasks become lines. The building scope and each tenant scope stay apart, so the owner never carries a tenant's cost.
Steps advance on their own. Tap a hex to hold it.
Bring the current task list to the walk. Modular prices the same zones so the two quotes line up row by row.
Modular Concepts cleans office buildings from a two-story professional address to a multi-tenant office park, across Massachusetts, Connecticut, and Rhode Island. The scope follows the building, and a portfolio can keep one contact for every address.
Along I-495 and Route 9 in Massachusetts, and the Hartford office market in Connecticut. Each building keeps its own lobby and restroom scope. The park keeps one contact.
Common-area scope for the owner: lobby, corridors, elevators, stairwells, shared restrooms. Suite scope per tenant, priced apart on the same quote.
One occupant and one scope, every floor on the building lines. A cafeteria hood can be added on a licensed visit.
Law, accounting, insurance, and engineering firms sharing one address. The landlord carries the corridor and the shared restrooms. Each firm carries its own suite.
Office floors stay on this page. Clinical suites follow the medical program, with their own scope and their own line.
Several buildings, one contact, one certificate per address. Nights can differ per building and still sit on one quote.
Ground-floor retail storefronts are outside this scope. A restaurant tenant can add licensed kitchen hood cleaning. Dining rooms and restaurant restrooms stay with that tenant's vendor. The tenant suite clean itself is on the office cleaning page.
These are real Google reviews from office customers Modular Concepts serves, quoted as written. Ask us for property manager references on a building like yours.
“Modular does the cleaning of our office and also the common areas of the commercial building we occupy in Marlborough for over 5 years, and throughout this entire time, we've experienced consistent high-quality services. Modular never asked us to sign a contract.”
“They understand what's needed and expected, and create a simple, direct, and cost effective plan that delivers exactly that. No contracts, no hassle. I strongly recommend Modular Concepts to any company looking for office cleaning, commercial cleaning, janitorial services, and related services such as strip and wax and carpet washing.”
“From the daily regular corporate office cleanings to specialized requests such as cleaning out the refrigerator, cleaning carpets, waxing floors, etc...every job is done to 100% satisfaction. I especially love that the owner will periodically stop in to make sure you are happy with the services provided.”
These are building-level questions. Suite-level questions for a tenant are answered on the office cleaning page.
Office building cleaning includes the building scope and the tenant scope, written and priced apart. The building scope is the lobby, elevators, corridors, stairwells, shared restrooms, and the dock, billed to the building. The tenant scope is each suite, its break room, and any private restroom, billed to that tenant or rolled into the building invoice. Day porter hours, floor and carpet programs, and window cleaning are add-on lines.
Yes, Modular can clean the common areas only. Many buildings start there: lobby, corridors, elevators, stairwells, and shared restrooms on a nightly schedule. Tenants can add suite service on the same night, priced apart, so the owner does not carry a tenant's cost. When a tenant signs on later, its line joins the same quote and the same crew.
Office building cleaning is priced per building after a walkthrough, with the building scope and each tenant scope as separate monthly lines. The areas in scope, how often each one is cleaned, and the task list for each visit set the number. Day porter hours are their own line. There is no long-term contract. Bring your current task list to the walkthrough so the two quotes line up row by row.
Yes, each address gets its own certificate of insurance naming the owner and the manager. 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.
Crews handle fobs and alarms by a written procedure for each floor. Names go on the building security log before the first visit. Fob and alarm steps are written per floor and kept with the assigned crew, so codes do not pass between crews. The space is secured on exit.
A missed area goes to the manager's one Modular contact, and the note reaches operations the same business day. A lobby or restroom miss is corrected sooner. Supervisor checks on a schedule catch many misses before a tenant does. Each visit closes with a sign-off the manager can read the next morning.
A day porter is worth it when the lobby or the shared restrooms stay busy all day. The night crew cannot reset them while tenants are in. The porter handles daytime resets, restroom checks, and conference rooms between meetings. The night crew does the heavier work. Porter hours are their own line, so you can add or drop them as traffic changes.
Yes, Modular cleans office buildings in Connecticut and Rhode Island as well as Massachusetts. Headquarters are in Marlborough, Massachusetts. Crews also cover the Hartford and Providence office markets, each building with its own certificate. A multi-state portfolio can keep one contact and one quote, with nights set per building.
