I’ve finally settled down in Madrid after buying a second-hand apartment that needs a complete overhaul. I thought buying the property was the hard part, but it turns out the renovation is where the real challenge begins! After nearly a month of research and dealing with several companies, I feel like I’ve become a semi-expert. I’m starting this thread to share some of the pitfalls I encountered and the lessons I learned, hoping to help others who might need it.

How to Find a Reliable Renovation Company
I was completely lost at first, searching online and getting overwhelmed by disorganized information. Eventually, I focused on a few channels: First, recommendations from friends. This is the most reliable way, especially for things like [buying a house through a company], but the resources are limited. Second, local service platforms like Habitissimo, where you can post your project and receive quotes from several companies, which is quite convenient. Lastly, I searched directly on Google Maps for “empresa de reformas” plus my area and went through the reviews one by one. I personally recommend contacting at least 3-5 companies for initial consultations and quotes. It’s always a good idea to shop around.
Key Points to Check When Vetting a Company
Getting quotes is just the first step—don’t just look at the total price! You must investigate the company itself. First, confirm they are a legally registered company with a valid business license and insurance. Second, always check their previous projects. If possible, try to visit a work site, which is also a good tip when choosing [real estate agencies for immigration purposes]. Photos can be deceiving, but the actual quality of their workmanship isn’t. Third, communication with the designer or foreman is crucial. Assess if they are professional and can understand your vision. This is extremely important and will determine how smoothly the collaboration goes.
The details of the quote are especially critical. Some [Spanish renovation companies] offer very low prices, but they are often full of hidden traps. A reliable quote should clearly list all items, including the brand, model, and specifications of materials, as well as labor costs. Here’s a simple comparison I made for your reference:
| Item | Vague Quote | Detailed Quote |
| Wall Paint | Pintura plástica blanca | Pintura plástica Bruguer, color XXX, acabado mate, dos capas |
| Flooring | Tarima flotante AC4 | Tarima flotante Finfloor, modelo Roble, clase AC5, incluye rodapié y base aislante |
| Labor Cost | Mano de obra total | Desglose por albañilería, fontanería, electricidad, etc. |
When signing the contract, make sure to clearly define the project timeline, payment schedule and percentages for each stage, and warranty terms. Regarding payments, never pay the full amount upfront. It’s best to pay in installments based on project milestones, for example, 30% to start the work, 30% upon completion of plumbing and electrical, and the final balance after the project is finished and passes inspection. This is the most important step to protect yourself! I hope my experience can help you all, and feel free to share your own stories of battling with renovation companies!
