Post-Construction Cleaning near you

On a real project the cleaning happens more than once, and quoting one visit for the whole thing is the single most common reason a post-construction clean disappoints. Each pass has a different purpose and a different tool set.

House dust is mostly soft. Construction dust includes hard mineral particles, and a cloth dragged across a new window, a glass shower panel or a stainless appliance can turn a cleaning pass into a scratching pass. That is why the sequence for a final clean is lift first, wipe second: HEPA vacuum everything, then wet-wipe with fresh water and clean cloths changed often, rather than pushing the same slurry around.

The volume also defeats ordinary equipment. Drywall dust clogs a domestic vacuum filter quickly and then blows the finest fraction back into the room, which is the reason the house seems dustier after cleaning than before. Joint compound residue on floors turns milky when it is wet-mopped and has to be removed rather than diluted. And a great deal of the dust is in places nobody thinks of as surfaces: the top edge of every door, the inside of every light fixture, the tracks of new windows, the interior of new cabinets, and the return grille of the HVAC system.

EPA's broader point about indoor air applies here too. It says the usually most effective way to improve indoor air quality is to eliminate individual sources of pollution or to reduce their emissions, and that for activities that generate high levels of pollutants, ventilation efforts should be maximized during those times. A post-construction clean is exactly such an activity, and it is also happening in a house full of new materials that are still off-gassing, so open windows and run exhaust fans throughout.

The rule attaches to the firm being paid to disturb the paint, not to the crew that comes afterward with buckets. EPA states that in general, anyone paid to perform work that disturbs paint in housing and child-occupied facilities built before 1978 must be certified in lead-safe work practices, and that the rule generally does not apply to homeowners doing projects in their own pre-1978 homes, although it does reach homeowners who rent the property out, operate a childcare center there, or buy and renovate homes for profit. EPA also notes that some jurisdictions run their own authorized programs instead of the federal one.

There is a size threshold. EPA interprets minor repair and maintenance activities as those that disrupt less than 6 square feet of painted surface per room for interior activities, or 20 square feet or less of painted surface for exterior activities, provided that none of the prohibited or restricted work practices are used and the work does not involve window replacement or demolition of painted surface areas. EPA adds that window replacement of any size is a renovation regardless of the area involved, and that jobs other than emergency renovations performed in the same room within the same 30 days must be considered the same job when deciding whether the work is minor repair and maintenance.

What this means when you hire post-construction cleaners is straightforward. Ask your contractor for the firm's certification and confirm that the required cleanup and verification procedure were completed as part of the renovation, before general cleaners are brought in. Hiring a cleaning company afterward does not make an uncertified renovation compliant and does not substitute for the rule's verification step. EPA's own lead-safe cleaning guidance describes the methods involved: mop uncarpeted floors thoroughly, clean walls with a HEPA vacuum or a damp cloth, thoroughly vacuum all remaining surfaces and objects, including furniture and fixtures, with a HEPA vacuum, and then wipe down all surfaces with wet disposable cleaning cloths until the cloths are clean. If you want independent proof, EPA notes you can hire a certified lead dust sampling technician, lead-based paint inspector or lead-based paint risk assessor to perform post-renovation dust-lead testing to confirm the work area is clean.

Cutting or grinding concrete, tile, brick, stone, mortar and some engineered products produces respirable crystalline silica, and OSHA's construction standard for it sets housekeeping rules that read like a specification for how a post-construction clean should be done. The standard applies to all occupational exposures to respirable crystalline silica in construction work, except where employee exposure will remain below 25 micrograms per cubic meter of air as an eight-hour time-weighted average under any foreseeable conditions.

Its two housekeeping provisions are the ones a homeowner can actually watch for. The employer shall not allow dry sweeping or dry brushing where such activity could contribute to employee exposure to respirable crystalline silica unless wet sweeping, HEPA-filtered vacuuming or other methods that minimize the likelihood of exposure are not feasible. And the employer shall not allow compressed air to be used to clean clothing or surfaces where such activity could contribute to exposure, unless it is used together with a ventilation system that effectively captures the dust or no alternative method is feasible. A crew that arrives with a push broom and a leaf blower for a house full of tile-cutting dust is not equipped for the job, whatever the price.

The chemical side is covered by the federal hazard communication standard, which applies to any chemical known to be present in the workplace in such a manner that employees may be exposed under normal conditions of use or in a foreseeable emergency, and requires labeled containers, accessible safety data sheets and employee training. Post-construction work often involves stronger products than household cleaning, including grout haze removers and adhesive solvents, so this is a fair thing to ask about before anyone opens a bottle inside your finished house.

The complaint after almost every renovation is that the dust returned. Usually it did not return, it was never fully removed: it is resting in the duct runs, in the return plenum and on the blower wheel, and every heating or cooling cycle re-seeds the house. Change the HVAC filter at the end of the project and again a few weeks later, and expect the second one to look worse than you think it should.

That is different from having the ducts professionally cleaned, which is a decision worth making on evidence rather than on reflex. EPA does not recommend that air ducts be cleaned routinely, but only as needed, and says duct cleaning has never been shown to actually prevent health problems, while listing ducts clogged with excessive amounts of dust and debris where particles are actually released into the home among the situations that warrant it. A major renovation with unprotected returns can produce exactly that situation, so ask to see inside a duct before agreeing, and note EPA's point that no chemical biocides are currently registered for use in internally insulated air duct systems and that routine use of duct sealants is not recommended.

Ventilation finishes the job. New cabinets, paint, adhesives, flooring and caulk are all still emitting, and EPA's guidance is to always ventilate and follow manufacturers' instructions when using products or appliances that may release pollutants into the indoor air, and to open windows and doors or run an air conditioner with the vent control open when weather permits. Keeping indoor humidity between 30 and 50 percent, which EPA recommends, also matters more than usual while construction moisture is still leaving the building.

This is priced on dust volume and finish sensitivity rather than on room count. What moves a quote is how much of the house was in the work zone and whether it was contained, how many passes are being quoted, the quantity of new glass and whether label and splatter removal is included, the floor types and whether grout haze or a curing wood finish is involved, the number of new cabinets and drawers to be cleaned inside, how much debris removal and hauling is in scope, and whether the crew brings HEPA vacuums and enough clean water and cloths to do the job by lifting rather than smearing. Ask explicitly whether the price covers one visit or the rough, final and touch-up sequence.

LokalMatch handles the introduction. You describe the project once, what was built or renovated, which rooms were affected, which trades have finished, what the new finishes are and whether you need one pass or several, and cleaning companies in your area that take this work receive the request. Those interested get in touch. Pros pay for the requests they receive, and using LokalMatch costs homeowners nothing. LokalMatch does not perform cleaning or construction, does not set prices, and does not vet, rank or recommend any company, so confirming insurance, the number of visits included and your contractor's own lead certification where the home predates 1978 stays with you.
