Detailed Post-Construction Cleaning Services in Greater Boston
A construction or renovation project is an exciting investment, but once the builders leave, the job isn’t truly finished. The site is often left with a thick layer of fine dust, stray debris, and smudges that standard janitorial services are not equipped to handle. This final, crucial step requires a specialized, detail-oriented approach to transform the site from a work zone into a pristine, move-in-ready space.
McGarr Service Corporation is the premier choice for post-construction cleaning in the Greater Boston area. We partner with general contractors, property managers, and business owners to provide the meticulous final clean that makes your new space shine.


Why a Specialized Construction Clean-Up is Critical
This is not just a cleaning service; it’s the final phase of your project, ensuring a successful handover.
Ensure Health and Safety
Construction dust can contain fine particulates, silica, and other materials that are hazardous to breathe. Our crews use proper PPE and filtration vacuums (HEPA) to capture and remove this dust, ensuring safe air quality for the first occupants.
Prepare for Final Inspections
We ensure the space is spotless and meets the cleanliness standards required to pass final inspections from owners, tenants, or municipal authorities.
Showcase the Quality of Work
A professionally cleaned site allows the quality craftsmanship of the architects, designers, and builders to be fully appreciated. It’s the finishing touch that highlights the true value of the project.
Save Time and Hassle
Our experienced team has the right tools, products, and processes to clean the site efficiently and correctly the first time, preventing delays in occupancy.
The McGarr Process: Our Multi-Phase Approach to Perfection
A true post-construction clean is a systematic, top-to-bottom process that leaves no surface untouched.
Phase 1: The Rough Clean
After all construction debris is removed, we perform an initial pass to remove all remaining small debris, stickers, and plastic coverings. This includes a preliminary sweep and vacuum of all surfaces.
Phase 2: The Detail Clean
This is the most intensive phase. We work from the top of the room down, meticulously cleaning every surface.
- Dusting and wiping all ceilings, light fixtures, ductwork, and pipes.
- Cleaning the insides of all cabinets, closets, and drawers.
- Washing interior windows, sills, and tracks.
- Cleaning and disinfecting kitchens and restrooms, including all fixtures and appliances.
- Wiping down all walls, baseboards, doors, and frames.
- A deep vacuum and/or scrub of all flooring.
Phase 3: The Final Touch-Up Clean
Just before the space is handed over, we perform a final pass to remove any dust that has settled. We polish all surfaces, vacuum carpets one last time, and ensure the space is absolutely perfect and ready for move-in.
