Routine Cleaning Services
Recurring cleaning contracts are the core of what Frisco Brothers does. Most clients are on weekly or bi-weekly schedules, with daily and one-time options available.
Office cleaning services covers trash removal, restroom sanitation, surface disinfection, floor care, and break room cleaning on daily, weekly, bi-weekly, or one-time schedules. Each contract is scoped to the facility during a free walk-through so the quote reflects actual conditions. For a full breakdown of what a commercial office cleaning contract includes and how to choose a schedule, see our office cleaning services page. Frisco businesses can also find local client examples and Frisco-specific scheduling detail on the office cleaning in Frisco page.
Day porter services places a Frisco Brothers crew member on-site during business hours to handle cleaning tasks as they come up: restroom checks, lobby touchups, spill response, and high-traffic area maintenance. Medical offices, gyms, daycares, and any facility where a single nightly clean cannot keep pace with foot traffic commonly add this service. For scope and contract structure, see our day porter services page.
Restroom supply restocking (paper towels, toilet paper, hand soap, and feminine products) is available as a contract add-on for clients already on a recurring cleaning schedule.
For Plano and McKinney businesses in the roster, dedicated coverage details are on the office cleaning in Plano and office cleaning in McKinney pages.
Floor and Carpet Care
The crew handles the full range of hard floor and carpet maintenance. Floor technician Erik Larsson brings 30+ years of specialized experience to this work and operates the truck-mounted extraction system used on both commercial and residential accounts.
Floor stripping and waxing covers VCT and hard floor maintenance: stripping old finish, applying new protective coats, and buffing to a commercial standard. The floor stripping and waxing page covers the full process, coat counts, drying times, and how to schedule around business hours. For Frisco office buildings specifically, see floor cleaning in Frisco.
Carpet cleaning uses the truck-mounted extraction system for deep commercial carpet cleaning. Both commercial and residential carpet extraction are available. The carpet cleaning page covers extraction methods, residential service, and how the truck-mounted system differs from portable units.
Tile and grout restoration clears grout line buildup and surface staining in commercial restrooms, kitchens, and common areas. Scope and scheduling are on the tile and grout restoration page.
Concrete sealing and polishing is available for warehouse floors and hard-surface commercial areas. Details on warehouse and industrial applications are on the concrete sealing and polishing page.
Window Cleaning
Mark and Sandra’s team cleans commercial and residential windows using the same commercial-grade crew and equipment for both types of work.
Commercial window washing covers office buildings and storefronts of all sizes on recurring or one-time schedules. The commercial window washing page covers building types, scheduling options, and what multi-story service involves. Frisco-specific building service is detailed on the window cleaning in Frisco page.
Residential window washing is available to homeowners in the service area using the same commercial-grade approach. Scope and availability are on the residential window washing page.
Specialty and Move Services
These services are available as standalone contracts or as add-ons to an existing recurring cleaning agreement.
Move-in and move-out cleaning covers commercial and residential transitions. New construction activity in Celina, Aubrey, and Savannah generates frequent requests in the northern part of the service area. The move-in and move-out cleaning page covers residential and commercial transitions, including new-construction final cleans.
Upholstery and office chair cleaning is a contract add-on for offices, daycares, and medical waiting rooms with fabric seating. Scope is on the upholstery and office chair cleaning page.
Eco-friendly cleaning is available on any contract at no additional charge and is the standard approach on accounts that serve children, medical patients, or other chemical-sensitive environments. The eco-friendly cleaning page covers the products used and the environments where green cleaning options apply by default.
Warehouse and industrial cleaning covers high-square-footage commercial facilities, including active manufacturing environments. The Simpson Strong-Tie manufacturing facility, served at 750,000+ square feet for 23 years, is the scale reference for this work. Warehouse and industrial cleaning scope, crew sizing, and large-account details are on the dedicated page.
