Professional Cleaning After Construction and Renovations
What Gets Left Behind After a Renovation
When a renovation finishes, the space is not ready to use. There is a layer of fine dust that gets into every corner, paint residue on windows and frames, cement splatters on floors and adhesive tape residue on baseboards.
There are also silicone remnants on window joints and a general build-up of construction dirt that regular household cleaning cannot handle.
A Specialist Job
Post-construction cleaning is not about mopping the floor. It requires specific products for each type of surface, professional tools (scrapers, industrial vacuums, steam cleaners), knowledge of materials and the patience to make multiple passes until the fine dust stops reappearing.
Barcelona, a City in Permanent Renovation
Flats in the Eixample are renovated to restore original hydraulic tile floors and open up spaces that were divided into small rooms for decades. In Gràcia and El Born, old buildings are rehabilitated floor by floor.
In Poblenou, industrial warehouses are converted into lofts and offices. Each type of renovation leaves a different kind of dirt, and our team has experience with all of them.

The 6 Phases of Our Post-Construction Cleaning
Phase 1: Debris and coarse waste removal
We remove all construction waste, packaging and leftover materials. Sweeping and collection of rubble, plaster chunks, wood offcuts and other debris. The space is cleared for the following phases.
Phase 2: Dust elimination
The most important phase. Construction dust is ultra-fine and resettles after the first pass. We make several passes: first dry vacuuming of surfaces, shelves, inside cupboards, top of door frames, inside wardrobes, skirting boards, behind radiators. Then wet cleaning to capture remaining particles. We clean inside every cupboard and drawer because construction dust penetrates closed doors.
Phase 3: Surface cleaning
We go over walls to remove the dust film. Cleaning of all surfaces (worktops, shelves, window sills). Bathroom fixtures descaled and polished. Kitchen appliances cleaned inside and out, even if they are new, because they accumulate dust during the build.
Phase 4: Windows and glass
Removal of paint splatters, adhesive residue, sticker marks and cement splatters on windows, mirrors and glass surfaces. We use professional scraping tools and solvents that remove residue without scratching the glass.
Phase 5: Floor treatment
Floor cleaning according to the material: ceramic tile, hydraulic tile (common in Barcelona's historic flats), parquet, marble or polished concrete. Cleaning of grout with cement and plaster residue. Removal of protective film from new tiles where applicable.
Phase 6: Final inspection and touch-up
We go through every room checking for anything that may have been missed, residual dust, marks on glass. Final photographs for delivery documentation. The property is handed over ready to use, photograph or list.


The Process: From Finished Build to Liveable Space
1. Initial Assessment
We visit the space once the construction is finished (or when it is a few days away). We photograph every area, identify the floor and wall materials, and pinpoint the zones with the heaviest build-up of dirt. With this information, we prepare the quote and plan the team and products needed.
2. Debris and Waste Removal
We remove leftover building materials, packaging, protective plastics, masking tape and any waste the builders have left. If there is rubble requiring a skip, we coordinate with the owner or the construction company.
3. First Pass: Dust and Coarse Residue
We vacuum with industrial equipment all surfaces, starting from ceilings and walls downward. We remove paint, cement and plaster stains from windows, frames, floors and fixtures with professional scrapers and specific products. We mop floors with products suited to the material.
4. Second Pass: Fine Cleaning
Fine plaster and sanding dust resettles after the first pass. The second cleaning covers all surfaces again: worktops, shelves, door frames, skirting boards, inside cupboards, appliances, fixtures and windows.
This is the phase where you see the difference between a professional clean and an improvised one.
5. Bathrooms and Kitchen
Full disinfection of fixtures, taps, shower tray or bathtub, toilet and sink. In the kitchen: worktop, sink, hob, inside and outside of new appliances (which come with stickers, plastics and dust). Cleaning of new tile grout that still has grouting residue.
6. Final Review and Handover
We go through every room checking that no residue remains in corners, window frames, inside drawers or behind doors. If anything is not perfect, we fix it before signing off on the job. We send photos of the result to the owner or the construction company.

Frequently Asked Questions About Post-Construction Cleaning in Barcelona
It depends on the scope of the work. A bathroom or kitchen renovation usually takes one full-day pass. A complete renovation of an 80 m² flat needs at least two passes: the first to remove the thick layer of dust, debris and material residue, and the second for fine cleaning of surfaces, windows and details. Jobs with heavy plaster dust or sanded walls may need a third pass because the fine dust resettles after the first cleaning.
A standard 70-90 m² flat with a full renovation typically requires 1 to 2 working days (depending on the number of passes needed). A partial renovation (one bathroom, one kitchen) can be completed in half a day. Large-scale builds or entire buildings may require several days with an expanded team.
Yes. Barcelona has many buildings with original hydraulic tile floors, marble and natural stone. Our team knows these materials and uses pH-neutral products that clean without causing damage. For parquet and hardwood, we dry immediately to prevent moisture from swelling the wood. We always test products on a small area before applying them to the full surface.
Yes. We use professional scrapers, material-specific solvents and techniques that remove residue without damaging the surface. Paint splashes on windows, cement splatters on floors, silicone stains on window frames, adhesive tape residue on baseboards. Each material gets its own treatment.
Yes. We collaborate with construction firms, architecture studios and developers who need to hand over spaces ready for use or sale. We adapt to your project delivery deadlines and can schedule the cleaning for the day after the build is completed.
Fine plaster and sanding dust tends to resettle after the first cleaning. That is why full renovations need at least two passes. In the first, we remove most of the dust and coarse debris. In the second, we deep-clean all surfaces once the fine dust has settled. If needed, we do a third pass until the space is spotless.
The price depends on the size of the space, the type of construction and the level of dirt. There is no standard price because every job is different. We visit the space once the work is finished (or close to finishing), assess the work needed and send a detailed quote within 48 hours. No obligation.
Yes. Cleaning of windows, window frames and shutters is included in the standard post-construction cleaning service. We remove paint residue, adhesive tape, plaster dust and cement splatters. Windows are cleaned on the inside. If the construction affected the exterior (facade painting, for example), we also clean them on the outside for accessible floors.
Contact us via WhatsApp at 613 888 538 or through the form on this page. Ideally, get in touch a few days before the construction ends so we can schedule the assessment visit and have everything ready to clean as soon as the builders finish. The sooner we come in, the sooner you can use the space.
Yes. In addition to flats and homes, we clean commercial spaces, offices, restaurants and any space that has been renovated. Commercial builds often have tight delivery deadlines and we adapt so you can open or resume operations as soon as possible.
