4. Apply primer or base sealant
A primer or base sealant layer is applied to improve adhesion and enhance the waterproofing effect of subsequent products. This process is especially important for work on specific façade areas or partial basements (between 1,200 € and 1,800 €) where maximum protection is needed.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Area to be waterproofed
The total area in square meters is the primary factor that determines the budget. The larger the surface, the more material and labor time required.
Type of area and location
Areas with greater water exposure (terraces, balconies, basements) require more robust treatments than other areas. Accessibility and height also influence the final cost.
Previous condition of the surface
If the area has cracks, active leaks, or previous damage, additional repairs will be necessary before applying the waterproofing material, increasing the budget.
Waterproofing system and material chosen
There are different options: liquid membranes, asphalt strips, waterproof paints, or polyurethane systems. Each option has different costs and durability.

Partial Home Waterproofing Cost and Price Guide
Partial waterproofing services for homes or commercial properties.
Partial waterproofing work includes evaluation of the affected area, cleaning and surface preparation, application of waterproofing membranes or specific products, and necessary finishing. The cost will depend mainly on the extent of the area to be treated, the type of product used, and the complexity of access. In Spain, prices for this type of service range from 300 € to 2,500 € depending on the characteristics of the job.
It is important to correctly diagnose the source of moisture before applying any treatment. An experienced professional will assess whether the solution requires only surface waterproofing or if intervention in structural elements is necessary. Regular prevention and maintenance of these areas can prevent major and costly future problems, such as structural damage or mold growth.
Partial waterproofing for residential properties or commercial spaces in Spain typically ranges from €800 to €3,500, depending on the scope of work and affected area. This service addresses localized moisture issues without requiring a complete structural waterproofing overhaul, making it an economical solution for homeowners and business operators dealing with specific problem areas. The price can vary significantly based on factors such as the size of the affected zone, the type of waterproofing material used, and the complexity of application. Understanding the cost structure helps property owners budget appropriately and avoid unexpected expenses during the renovation process.
When requesting quotes for partial waterproofing services, it's essential to get detailed estimates from multiple professionals to ensure competitive pricing and quality workmanship. A professional quote should clearly outline the materials to be used, labor costs, timeline for completion, and any warranty or guarantee on the work performed. The price per square meter typically ranges from €40 to €150, with variations based on accessibility, existing damage assessment, and the specific waterproofing technique required. Regional differences across Spain can also influence final pricing, so obtaining local quotes provides the most accurate cost estimates for your particular location.
Investing in professional partial waterproofing prevents costly water damage repairs down the line and protects your property's structural integrity. Rather than attempting DIY solutions, hiring a qualified professional ensures proper application and long-lasting results. When comparing quotes, don't base your decision solely on the lowest price; consider the professional's experience, materials quality, and offered guarantees. A slightly higher investment upfront often results in superior protection and greater peace of mind, making it worthwhile to select experienced professionals who stand behind their work with solid warranties.

Frequently Asked Questions
How long does a partial waterproofing last?
Durability depends on the type of material used and the conditions of the area. Basic waterproofing with waterproofing paint typically lasts 2-3 years. Medium-quality liquid membranes last 5-7 years, while premium systems with geotextile can reach 10 years or more. Regular maintenance and annual inspections significantly extend the useful life of the treatment.
Is it necessary to vacate the property during the work?
It is not essential in most cases of partial waterproofing, as these are minor works. However, it is recommended to vacate the specific area to be treated to facilitate the work and avoid problems with vapors or chemical products. If it is a small bathroom or kitchen, the work can be completed in just a few hours. For larger areas such as basements or terraces, it is ideal to have full access for 2-4 days.
What is the difference between partial and complete waterproofing?
Partial waterproofing treats only areas with specific problems, such as a balcony, terrace, or bathroom, and is much more economical. Complete waterproofing addresses the entire property or structure, including roofs, facades, and foundations, with a significantly higher cost (from 5,000 € onwards). For localized problems, partial waterproofing is the most efficient and cost-effective solution.
Can I apply waterproofing myself?
Some waterproofing products are designed for DIY application, such as simple waterproofing paints. However, for a lasting and professional result, it is recommended to hire a specialist. Professionals correctly assess the causes of moisture, properly prepare surfaces, apply uniform coats, and guarantee the work. Poor DIY application can result in recurring problems in the short term, being more costly in the long run.
How do I know if my property needs waterproofing?
Main signs include moisture stains on walls or ceilings, visible mold or fungi, musty odor, paint peeling, or leaks during rain. There may also be white efflorescence on surfaces. If you observe any of these symptoms in specific areas such as basements, balconies, or bathrooms, it is recommended to request a free professional evaluation. A specialist will diagnose whether you need waterproofing and what type is most appropriate.
