You have just spent months planning and executing a renovation in Barcelona. The new kitchen is installed, the bathroom tiles are finally grouted, the walls have a fresh coat of paint. The contractors packed up and left. And now you are standing in your apartment looking at a construction site covered in a fine layer of white dust, cement smears on the floor, paint splatter on the windows, and debris in every corner. You cannot move in like this. Regular cleaning products and a household vacuum are not going to cut it.

Post-construction cleaning in Barcelona is a specialised service that requires industrial equipment, specific chemical products, and a team that knows the difference between plaster dust and cement residue (because they require completely different removal techniques). This is not something you should attempt yourself. Construction dust contains silica particles that are harmful to breathe, cement residue bonds to surfaces and becomes harder to remove with every passing day, and using the wrong product on the wrong surface can cause permanent damage to your new finishes.

Barcelona has a thriving renovation culture. The city is full of beautiful but aging apartments, particularly in Eixample, Ciutat Vella, Gracia, and Sants, where expats and locals alike buy older properties and do a reforma integral (full renovation). If you are reading this page, you have probably just been through that process. Our team has cleaned after hundreds of renovations across Barcelona, from complete gut-and-rebuild jobs in modernist Eixample flats to bathroom-and-kitchen updates in Poblenou lofts. We know exactly what to expect and how to handle it.

What post-construction cleaning includes

A proper post-construction clean typically happens in two to three passes. The first pass removes the bulk of debris and heavy dust. The second pass addresses surfaces, fixtures, and details. A third pass (for larger or more intensive renovations) focuses on fine dust removal and final polishing. Here is what we cover:

Dust removal (the biggest challenge)

  • Construction dust is not normal dust. Plaster, cement, and drywall dust is ultra-fine and gets everywhere: inside closed cabinets, behind radiators, inside electrical outlets, on top of door frames, inside light fixtures, in every crack and crevice. Our HEPA-filter industrial vacuums capture particles down to 0.3 microns, preventing the dust from simply being redistributed into the air.
  • Multi-pass approach: We vacuum all surfaces first (floors, walls, ceilings, fixtures), then wet-wipe every surface, then vacuum and mop again after the residual dust has settled. This is why post-construction cleaning takes significantly longer than a standard deep clean.
  • Air quality: After we finish, the air in your apartment should be noticeably cleaner. If you have had windows closed during the renovation, the first proper clean also helps flush out volatile organic compounds (VOCs) from new paint, adhesives, and sealants.

Cement, grout, and mortar residue

  • Floor cleaning: Dried cement and grout haze on tiles is one of the most common post-renovation issues. We use pH-specific cleaning agents matched to your floor type. For ceramic and porcelain tiles, a mild acid-based cleaner dissolves cement residue safely. For natural stone (marble, limestone) and hydraulic mosaic tiles common in Barcelona, we use alkaline or pH-neutral products to avoid etching the surface.
  • Wall and surface residue: Cement splashes on painted walls, grout smears on new tiles, and adhesive residue from protective tape are all carefully removed without damaging the finish underneath.
  • Bathroom fixtures: New bathroom installations often leave a film of grout dust and silicone residue on taps, shower screens, toilets, and sinks. We clean and polish every fixture until it looks as the manufacturer intended.

Paint splatter and adhesive removal

  • Windows and glass: Painters rarely manage to keep windows perfectly clean. We remove paint spots from glass using appropriate solvents and razor blade scrapers (on glass only, never on coated or tinted surfaces). We also clean adhesive residue left by masking tape and protective film.
  • Door frames and hardware: Paint drips on door handles, hinges, and electrical switch plates are carefully removed.
  • Flooring: Paint drops on hard floors are treated with solvents appropriate to the floor material and paint type. We test in an inconspicuous area first.

Fixtures and fittings

  • Kitchen: New kitchens come with protective plastic film, stickers, and packing residue. We remove all of this, clean inside every cabinet and drawer, and polish all surfaces and appliances so they are ready to use.
  • Bathrooms: Sanitaryware cleaned, taps descaled if water has been running during construction, shower enclosures polished, mirrors cleaned.
  • Built-in wardrobes: Interior shelves wiped clean of construction dust. Rails and fittings polished.
  • Electrical fittings: Switch plates, plug sockets, and light fixtures cleaned of dust and paint marks.

Balconies, terraces, and common areas

  • Outdoor spaces: Balconies accumulate significant construction debris. We sweep, scrub, and mop balcony floors, clean railings, and remove any cement or paint from outdoor surfaces.
  • Building common areas: If your renovation has affected the communal staircase (which it almost certainly has in a Barcelona apartment building), we clean the areas impacted by your works. This keeps your neighbours happy and avoids complaints to the comunitat de propietaris (homeowners' association).

Post-construction cleaning prices in Barcelona

Our pricing is based on the size of the property and the extent of the renovation work. Here are our standard rates:

Property size Full renovation (reforma integral) Partial renovation Estimated time
Up to 50m² 600-750€ 350-500€ 1-1.5 days
50-80m² 750-1,000€ 450-650€ 1.5-2 days
80-120m² 960-1,500€ 600-900€ 2-3 days
120m²+ From 1,500€ From 900€ 2-4 days

VAT included in all prices. "Full renovation" means all rooms were affected (walls taken down, new flooring, new kitchen and bathrooms). "Partial renovation" means work was limited to specific rooms (typically kitchen and bathroom) with the rest of the apartment largely unaffected.

What affects the final price

  • Type of renovation: A full reforma integral generates far more dust and debris than a bathroom refit. The former requires 2-3 passes over multiple days; the latter might be done in a single day.
  • Type of surfaces: Hydraulic mosaic tiles, marble, and natural stone require specialised products and more careful handling than standard ceramic tiles. New hardwood floors need specific post-installation cleaning.
  • Windows and glazing: If the renovation included window replacement, cleaning new windows (removing stickers, protective film, adhesive residue) adds time. Large windows or floor-to-ceiling glass walls in modern buildings are particularly time-consuming.
  • Debris left behind: Ideally, your contractor removes all construction rubble and large debris before we arrive. If significant rubble remains, we can arrange removal but this is quoted separately.
  • Building access: Fifth-floor walk-ups in the Gothic Quarter or El Raval mean our team carries all equipment upstairs. This does not change the price but we factor it into scheduling.

Every post-construction clean gets a personalised quote. Send us a few photos of the current state and tell us what work was done, and we will have a detailed estimate back to you within 2 hours.

Renovating in Barcelona: what expats should know about the clean-up

If you are an expat who has recently bought or rented an apartment in Barcelona and decided to renovate, you have probably already navigated the maze of building permits (llicencia d'obres), approval from your comunitat de propietaris, and finding a reliable contractor. The renovation itself is stressful enough. The clean-up afterwards should not be.

Why Barcelona renovations are particularly messy

Most Barcelona apartments are in buildings constructed between 1860 and 1960. When contractors open up walls in an Eixample flat, they encounter layers of history: original brick walls, lime mortar, old electrical conduits, sometimes even remnants of previous renovations from decades past. Demolishing a wall in a 120-year-old building generates a type of dust (fine lime and plite particles) that is different from modern drywall dust and requires specific cleaning approaches. The dust is finer, more persistent, and gets into places you would never imagine.

Common renovation types in Barcelona

  • Reforma integral: A complete renovation of the entire apartment. Walls come down, new electrical and plumbing throughout, new kitchen and bathrooms, new flooring, everything repainted. This is the most common type of renovation for expats buying older apartments. It generates the most construction mess and requires the most thorough post-construction clean.
  • Kitchen and bathroom renovation: The second most common type. Even though the work is limited to one or two rooms, the dust and debris spread throughout the apartment through doorways and ventilation.
  • Painting and cosmetic updates: Repainting, new flooring, updated fixtures. Less dust but still leaves paint splatter, adhesive residue, and fine particles that need professional removal.

Dealing with your community of neighbours

Barcelona apartment buildings are managed by a comunitat de propietaris. Renovation works almost always affect common areas: dust in the stairwell, debris near the entrance, noise complaints. As part of our post-construction cleaning service, we can clean the communal areas affected by your renovation. This is not just a courtesy. Many communities in Barcelona will charge you for cleaning common areas if you do not handle it yourself. Having your cleaning team take care of it pre-emptively avoids conflict and additional costs.

Timing your clean-up

Do not wait weeks after the renovation to book the clean. Cement residue hardens further over time and becomes exponentially harder to remove. Paint splatter dries and bonds to surfaces. Dust settles into grout lines and becomes embedded. The sooner you clean after the builders leave, the easier (and cheaper) the job is. We recommend booking us for 24-48 hours after the last construction work is completed.

Why you need professional post-construction cleaning

Some people consider doing the post-renovation clean themselves to save money. Here is why that is almost always a mistake:

Health hazards

Construction dust is not household dust. It contains silica particles (from plaster, concrete, and morite), chemical residues from adhesives and sealants, and potentially lead or asbestos fibres in older Barcelona buildings (pre-1980s construction). Breathing this dust without proper respiratory protection causes real health problems. Our team uses PPE (personal protective equipment) and HEPA-filter vacuums that capture these particles instead of blowing them around the room, which is exactly what a household vacuum does.

Surface damage from wrong products

Using the wrong cleaning product on the wrong surface can cause irreversible damage to your brand-new finishes. Acidic products on marble floors etch the surface permanently. Bleach on hydraulic tiles destroys the pigments. Abrasive cleaners on stainless steel appliances leave scratch marks. Acetone on certain types of plastic or laminate causes discolouration. We know which product works on which surface because we do this every week. The cost of replacing a damaged surface is always far higher than the cost of professional cleaning.

Time and effort

A post-construction clean of an 80m² apartment takes a professional team of 2-3 people approximately 12-16 hours of work spread over 1-2 days. Doing it yourself, without industrial equipment, would take significantly longer and produce worse results. Most people who attempt it end up calling us anyway after spending an entire weekend and still finding dust in every corner.

Results that match your investment

You have invested thousands (often tens of thousands) of euros in your renovation. A professional post-construction clean ensures your finished apartment looks as good as it should. Every surface gleaming, every fixture polished, every trace of construction work gone. This is particularly important if you are renovating a property for rental (Airbnb or long-term). The first photos you take of the apartment will define its earning potential, and those photos need to show a flawless space.

Post-renovation cleaning across Barcelona

We clean after renovations in every neighbourhood of Barcelona. These are the areas where we handle the most post-construction jobs:

  • Eixample (Dreta, Esquerra, Sagrada Familia, Sant Antoni) — The neighbourhood with the highest volume of apartment renovations in Barcelona. Modernist buildings from the 1890s-1920s with high ceilings, ornate details, and original hydraulic tile floors that need expert care during cleaning.
  • Ciutat Vella (Barri Gotic, El Born, El Raval) — The oldest buildings in Barcelona. Renovations here often uncover unexpected structural elements. Narrow staircases with no lift mean our team carries all equipment by hand, but we are very used to it.
  • Gracia (Vila de Gracia, Camp d'en Grassot) — Popular with expats and young professionals buying their first Barcelona apartment. Many small to medium renovations in 60-80m² flats.
  • Poblenou and 22@ — Former industrial area with loft conversions and modern new-builds. Post-construction cleaning here often involves large open-plan spaces and floor-to-ceiling windows.
  • Sarria-Sant Gervasi — Larger properties including houses and duplexes. Premium renovations with high-end materials that require particularly careful cleaning.
  • Sants-Montjuic (Poble-sec, Sants) — Growing area for apartment purchases and renovations. Good value properties with increasing renovation activity.

We also cover the metropolitan area including L'Hospitalet, Badalona, Sant Cugat, and Castelldefels. If your renovation is outside central Barcelona, contact us to confirm availability and pricing.

Frequently Asked Questions

We can start as soon as the builders have finished and removed their tools and materials. Ideally, we recommend waiting 24-48 hours after the last coat of paint has been applied so it has time to cure fully. If your contractor is still finishing small touch-ups, we can work around them, but the most efficient approach is to come in once all construction work is genuinely complete. We coordinate directly with your contractor if needed to find the right timing.

Post-construction cleaning requires industrial-grade equipment that goes far beyond a regular mop and bucket. We use HEPA-filter vacuum cleaners that capture fine construction dust (plaster, cement, and silica particles), professional floor scrubbing machines for removing dried mortar and grout haze, steam cleaners for stubborn residues, and specialised scraping tools for paint and adhesive removal on glass and tiles. All of this equipment is brought by our team — you do not need to provide anything.

Yes, but it requires careful technique. Barcelona’s hydraulic mosaic tiles (mosaics hidraulics) are porous and sensitive to acidic products, so we never use standard cement removers on them. We use pH-neutral solutions and manual scraping with plastic blades to avoid scratching the surface. For paint splatter on tiles, we use appropriate solvents depending on the paint type (water-based vs oil-based). If the tiles have been heavily affected, we may recommend a professional tile restoration specialist after our cleaning.

Our standard rate is 12-15€ per square metre, depending on the scope of the renovation. For a typical 80m² apartment that has undergone a full renovation (reforma integral), expect a total cost of approximately 960-1,200€. A partial renovation (bathroom and kitchen only, for example) in the same size apartment might cost 500-700€ because less of the living space is affected. We provide a precise quote after you describe the work that was done and ideally share a few photos of the current state.

Absolutely. Windows are one of the most affected areas during a renovation. We clean all interior and accessible exterior glass, removing paint spots, adhesive residue from protective tape, plaster dust, and cement splashes. Window frames and tracks are vacuumed and scrubbed clean. Balconies are swept, mopped, and degreased if necessary. If your renovation included new windows, we also remove manufacturer stickers and protective film residue.
